There are many families of radiators are equipped with temperature control valve, heating temperature control valve can achieve temperature control, so that the effect of energy savings. This adds a lot of convenience to our use of radiators. However, we still need to understand the working principle and use of the heating valve. So how do you know about the working principle of heating and temperature control valve? The following shows the working principle of the heating temperature control valve and the use and use of the heating temperature control valve with the small series for your reference. Heating thermostat valve concept Heating temperature control valve, full name heating temperature control valve, is a typical application of flow control valve in the field of temperature control. Principle: By controlling the heat exchanger, air conditioning unit or other heat, cold equipment, a hot (cold) media inlet flow, in order to control the device outlet temperature. When the load changes, adjust the flow by changing the valve opening to eliminate the effect of load fluctuations and return the temperature to the set point. First, the radiator temperature control valve works Heating thermostatic valves can be divided into: self-operated thermostatic valves and electric thermostatic valves 1, self-heating thermostatic valve The self-heating heating temperature control valve mainly consists of a valve body, a valve core, a valve seat, an adjustment sleeve (adjustment screw), a return spring and the like. When the hot water enters the valve body, the temperature of the valve element is used to automatically control the opening of the valve, close or automatically adjust the opening degree of the valve, so as to achieve the purpose of automatically controlling the return water discharge temperature. The self-operated heating temperature control valve is installed on the water return branch of each radiator of the heating system. When the temperature of the return water in the radiator reaches the designed return water temperature, the valve will open automatically and return water will pass through. When the radiator return temperature is higher than the design return temperature, the valve opening automatically becomes smaller and closes directly. In this way, even if the loops of the heating system are out of balance due to design or construction, the control function of the self-operated temperature-controlled flow control valve can also be automatically balanced. The self-operated heating air temperature control valve is provided with an adjusting sleeve (adjustment screw) for adjusting the temperature of the discharged water. When the clockwise rotation adjusts, the drainage temperature decreases, whereas the drainage temperature increases. 2, electric heating temperature control valve The electric heating temperature control valve is composed of a temperature controller, an electric actuator, and a valve (valve body). When used, the temperature controller is installed on the wall of the interior wall of the room, and the room temperature can be fully sensed. The cable is connected with the electric actuator and the electric heat driver is connected with the valve. According to the heating needs, the user sets the indoor demand temperature on the temperature controller; when the room temperature reaches the set temperature, the positive temperature coefficient thermistor in the electric actuator starts to work, and the thermal expansion device is heated to close the valve; The room temperature is lowered, the thermostat is disconnected, the actuator is cooled, the expansion device contracts, and the valve opens. As a result, on-demand control of the room temperature is achieved to save heat. Heating control valve use and use (a) uses It is used for the automatic control of the thermal energy balance of hot water heating system and equipment. Solve the problem of thermal hydraulic imbalance caused by the different lengths of pipelines between buildings in the heating system, the size of the heat dissipation area, the unequal resistance due to different pipeline structure, the different pressure difference, and the unequal heat dissipation. . According to user needs, the following control methods are available: 1. Installed in the double pipe heating system or the water return branch pipe of each group of radiators with a closed pipe and single pipe heating system, the return temperature of the radiator can be controlled, so that the radiators can reach the balance of the hydraulic and thermal power. 2. When the floor is lower than four floors, install the valve at the bottom of the backwater riser of the hot water heating system to control the return water temperature of each set of riser and maintain the hydraulic balance among the riser risers. This method is economic and convenient. 3. When the floor is higher than six floors, the valve can be installed in the middle or bottom of the backwater riser of the hot water heating system to maintain vertical heat balance. 4. When the floor is high, in addition to installing at the bottom of the backwater riser, a valve may be installed on the back floor branch of the heating radiator on the floor to provide heat balance between the layers. 5. The self-operated thermostatic valve can also be installed on the return pipe of the building's hot inlet to control the total return water temperature of the building, ensure the hydraulic balance between the buildings, and avoid the hydraulic imbalance of the heating network. 6. The valve is also suitable for installation in schools, theaters, conference rooms and other intermittent use of heating places, when there is no one, you can adjust the return temperature to the heating temperature on duty, you can make the radiator does not freeze and crack can play The role of energy saving. (B) radiator temperature control valve use Radiator temperature control valve three-way temperature control valve, two-way temperature control valve, usually at home can be used two-way, while access to the radiator pipe, while access to the radiator; according to their points of view, can be divided into 90 degrees Angle valve and straight valve; equipment, its caliber giant subdivision, can be divided into 4 points diameter, 6 points diameter, as well as 1 inch diameter; according to their operating methods, can be divided into intelligent active temperature control valve, manual temperature control valve. Then, in combination, there are many types of user-selectable thermostatic valves based on the diameter of the radiator, the method of equipment, and other conditions. Radiator specification equipment is a set of radiator devices, two temperature control valves, but currently is a set of radiator temperature control valve, a flow control valve, so only need a temperature control valve to adjust the temperature. Radiator temperature control valve has 5 scales above it, 0-5, can be properly adjusted according to their own comfort. Some users said that their radiators do not have a thermostatic valve at their base. Because radiators rarely have too hot temperatures, they cannot be used. Summary: The working principle of the heating temperature control valve, the use of heating control valve and the use of related information for everyone to introduce here, I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible. Heating
What is magnetic track lighting system ?How to use magnetic track light to achieve various lighting methods?
Lamps can be installed without tools, a variety of lamp molds can be flexibly combined to adapt to a variety of lighting methods, fashion and simple modeling, strong sense of science and technology, magnetic track lamps with these characteristics quickly occupy the market, has become the love of many owners including designers.But there are also a lot of people who only hear the name, not see the shape,wondering what is the magnetic track lamp?
What is Magnetic Track Light?
Magnetic track light is on the basis of the traditional track lamp added magnetic connection structure, in the original advantages of the track lamp, more convenient installation and production of various lamp components, easy to daily maintenance and maintenance. At the same time, because the track is low-voltage power supply,the lamp body can be removed from the drive, so the track and lamps are more compact and delicate, in the case of power permits, according to the needs and uses, arbitrarily rely on lamps and lanterns, more convenient and fast, can form a unique sense of design.
How to use magnetic track light to achieve various lighting methods?
Now the use of magnetic lamp is often used in lighting design lamps, with the right use will become a bright spot in the design, with the wrong use will form a visual disaster. So how should we use magnetic track lights to achieve general lighting, key lighting, local lighting and decorative lighting?
General Magnetic absorption lamp (basic lighting, ambient lighting)
Light fixtures mainly provide light to Spaces such as ceilings, walls, floors, curtains, etc.
Ceiling and ground belong to horizontal plane lighting, which can adopt immobile linear module (floodlight and grid).The floodlight module provides wide and uniform soft light for the environment, while the grid module is suitable for anti-glare and focusing on the tea table of the living room sofa to enrich the level of environmental lighting.
These two modules are also suitable for walls, curtains and other facades to achieve the rhythmic wall washing effect of light spots, which is similar to the effect of down lights and spotlights. It is necessary to pay attention to not mixing and matching to avoid light spots
In addition, the magnetic folding grille light is also suitable for this kind of rhythmic facade lighting, but it is worth noting that there will be a distance of about 1 meter from the ceiling,which is not suitable for large area fading and washing wall
