Antifreeze type straight air pipe siphon tube solar water heaters
With the same pipe freezing problems, but the operation more difficult, the device reliability is also problematic, difficult to wide range of applications. Based on experience and experimental results, within a certain range of antifreeze tried several new methods: 1. Works on the hot water running in the main pipe section to install the rubber tube transformation. 2. Large-scale water projects in the pipeline lowest additional solenoid valves, pipe temperature ≤ l ℃, automatically open the drain, and turns off automatically to ensure the pipeline does not bear the frozen block. 3. Collective works polystyrene tubes commonly used in insulation, pipe and tube can be inserted between the Amoy combined with slots to improve the management interface of the insulation effect. 4. Are trying to install the product in the home with additional circulation pump, temperature ≤ l ℃ in the pipeline, the use of the pump to warm water in the tank of cold water pipe replacement, completely solve the freezing problem. (Continued from page 63) freezing in the winter season, after each time the full, open the valve 4, the empty product pipeline contractors, when compared with anti-cracking water, close the valve 3 and 4, open the valve I and 2, the first section of pipe filled with water, AB, AB section of the formation of the siphon pressure head, and then open the valve 3, to rely on siphon effect, the water tank from the spray nozzle. This device has the advantage of solar water heater in winter to prevent cracking of pipeline problems, saving insulation materials, simplifying the construction process r. Drawback is to ensure that every water user in the end, will the water emptying AB segment, once forgotten, is likely to pipe cracking, and block the overflow pipe freezing problems still exist; Another disadvantage When in the water,uggs sale, AB water-filled section is difficult to estimate when asked, at least satisfied segment AB, can not form a siphon pressure head, as much water from the overflow pipe in the overflow, resulting in waste. To solve the above problem, the valve 1 and valve 4 to set the solenoid valve, contact to the overflow port C Department, located in A at a level probe, water, the water a place full of A, the indicator light, indicating that the siphon pressure head has been formed, as shown in Figure 3. To do: When the tank when the water runs out, the electromagnetic valve 6 open, solenoid valve 7 is closed in Sheung Shui, water tank full of Figure 3, the Tian door 6 closed, the valve 7 to open, and set the working hours of the valve 7, to ensure adequate emptying of the AB section of water pipe siphon antifreeze c application methods, and with a solenoid valve, vacuum tube solar water heater in winter to solve the problem of easy cracking,uggs online, reduce maintenance,ugg italia, allowing users to use more convenient and reliable. lj down z, I siphon antifreeze type straight air pipe, device, rL 』? 'Mountain Academy of the late Provincial Energy Research Institute Chiang Peng Wang Shuqing Ma Shengliang Hongwu Wang Zhenbin vacuum tube solar water heaters as an economic, convenient, energy saving, safety products, by love of urban and rural residents, but in the north, the winter prone to cracking problems have prevented the tube solar water heater vacuum magnetron sputtering to further promote the glass tube Higher Education asked the city to resolve more than 18 ~ C r A solar water heater freeze protection areas problem. But solar water heater pipe in the water is still, and small heat capacity, so the existing conventional pipe insulation material to meet the winter without a l0 r the following areas of Tuen demand water heater pipes freeze, now without any thermal insulation material is introduced, relying on siphon Principles of water, automatic emptying of the new water pipe vacuum tube solar water heaters. Current conventional solar water heater installed as shown in Figure l. Sheung Shui,mbt calzature, the valve 12 to open, cold water enters the water heater tank to the overflow pipe. Close the valve I, 2. Water, close the valve I, open the valve 2,3, Yan door by adjusting the water nozzle 2 and l and the optimum temperature of the water by the disadvantage of such an installation, AB section of the pipeline in the outdoor installation of insulation, always full of water, once the temperature dropped, ranging from picking block, while in the cracking. But better in the winter sunshine, the temperature is below a 522, thermal expansion of water in the tank, overflow from the overflow pipe, overflow pipe dripping water in the process of Jibei frozen, causing the overflow pipe freeze plugging, affecting water heater normal use. New siphon solar water heater antifreeze shown in Figure 2. lL a Figure I Figure 2 cents in Figure l, t, based on the valve 3 at the Canadian side of the road before A, the valve installed on the road next to 4, B at the installation of a one-way inlet check valve 5, pipeline from the tank into the upper part, the El to the bottom of the tank,tory burch shoes, AB section of the pipeline without insulation. Sheung Shui, close the valve 3,4, open the valve 12, to the overflow pipe of the water, close the valve 1,2. (Turn page 57) 63
