Problems solved by technology
[0003] Since the pressure reducing valves currently on the market are not specially designed for direct-connected heating systems, some performance parameters are not completely suitable for heating systems
Therefore, it is directly used for decompression on the heating system, not only the shutdown function is not ideal, but also the exhaust function is missing.
In addition, they all have the disadvantages of complex structure, troublesome production, spring fatigue, rubber wear on the circulation surface, and high price. Especially when the system stops running, electric valves must be set to shut off. Not only frequent actions are easy to damage, but also sudden power failures occur. Shutdown unreliable fatal flaw
However, although the water tankless direct-connected heating system of high-rise buildings has effectively overcome the shortcomings of the above-mentioned pressure relief valves such as "shutoff, decompression, and exhaust", it belongs to an open system after all, and cannot be used for design because it is connected to the atmosphere. On heating systems with deaeration

Embodiment Construction
[0011] see figure 1 , The directly connected heating system of a high-rise building has a booster pump 1 and its control system, a check valve 3 and a radiator 6 in the high area, and a blocker 4 is set on the return water pipeline 7 in the high area. The booster pump and its control system are used to send the heating medium to the radiator in the high area. 8 is the radiator in the low zone.
[0012] see figure 2 , the blocker is pot-shaped, with water inlet pipe 9 and water outlet 16 arranged on the pot, the lower part of the water inlet pipe is provided with a decompression port 21, the upper end of the connecting rod 23 is fixed with a small piston 22, the lower end of the connecting rod is fixed with a large piston 17, and the small piston In the water inlet cavity, it is the disc of the decompression port, and the large piston is arranged in the large piston cavity 15. The lower part of the large piston cavity is connected with the high-pressure driving water pipe 2,...

The invention relates to a high-building direct heating system, which can solve the problems of present system that needs decreasing the dynamic and static pressures via depressurize valve and electromagnetic valve. The invention comprises: using a pressurize pump and a control system to pressurize the water of lower area of hot water heating system, via check valve to be fed to the high area to discharge heat; and the back water is depressurized via stop device; the front end of check valve via high-pressure driving tube is connected to the stop device of high-area back water tube. The invention can reduce the device, simplify the stop device and improve the system reliability.
Description
technical field [0001] The invention relates to a direct-connected heating system for high-rise buildings, which provides heat for high-rise buildings and low-rise buildings at the same time. Background technique [0002] The method of heating high-rise buildings and low-rise buildings at the same time is to provide a boiler for the high-rise buildings or to isolate the heat exchanger from the low-level system. The former has a large initial investment and high operating costs, while the latter must have a steam or high-temperature water heat source to be economical and reasonable. The most economical method is to use the low-temperature water heat source system in the original low-level area for direct connection heating, such as the direct connection heating system without water tank in high-rise buildings and the pressure reducing valve method that have appeared in recent years. [0003] Since the pressure reducing valves currently on the market are not specially designe...
