When high drive pipe 6 internal pressures rise, adjustable column 1 upwards slides along the lumen wall of low-voltage driving pipe 5 and high drive pipe 6, the thin position that runs to the adjustable column 1 of " dumbbell " shape structure just in time is communicated with intake pipe 3 and outlet pipe 4, this pressure regulating shutdown device is opened, when high drive pipe 6 internal pressures reduce, adjustable column 1 is under the effect that opens and closes spring 10 and adjustable column 1 deadweight, in low-voltage driving pipe 5 and high drive pipe 6 tube chambers, move downward fast, and drop on the tube chamber bottom of high drive pipe 6, making intake pipe 3 and outlet pipe 4 be conditioned post 1 cuts off, simultaneously under the effect of the sealing drum 12 that is arranged at intake pipe 4 tube walls, sealing drum 12 and adjustable column 1 sidewall contact seal, thereby thoroughly the water with intake pipe 3 is conditioned post 1 partition, makes water and pressure all can not transmit to outlet pipe 4, and this pressure regulating shutdown device turn-offs.When pressure regulating shutdown device is opened, can pass through relief frame 17, adjust the discharge pressure of water pipe 4.
Working principle: as shown in Figure 9, when the high rise building heating system moves, compression pump 19 is with the water supply pressurization of the low district of indoor and outdoor hot water heating pipe network 20, deliver to tall building (high district) radiator 21 heat releases, meanwhile, utilize high service that valve member is opened automatically in pressure regulating shutdown device 22, backwater is then by pressure regulating shutdown device 22 decompressions, then, turning back to low the district in the return pipe of heating networking goes; When system stopped, pressure regulating shutdown device 22 was closed automatically, with safety check 23, high sound zone system and low sound zone system are separated, thus the partition of assurance high low area system static pressure.
Pressure regulating shutdown device 22 of the present utility model here is exactly a vitals of undertaking automatic open and close of system and pressure regulation specially.
The utility model pressure regulating shutdown device 22 is such in the concrete working principle of high rise building heating system: compression pump 19 is opened, water supply pressurization with outdoor low district hot water heating pipe network 20, after upwards delivering to radiator 21 heat releases of (high district) of tall building, enter pressure regulating shutdown device 22, turn back to then in the low district pipe network and go.Meanwhile, utilize the water pressure of high drive water pipe 24 upwards to promote adjustable column 1 in pressure regulating shutdown device 22, run to cross through hole 7 and just in time be communicated with intake pipe 3 and outlet pipe 4, this pressure regulating shutdown device is opened.
When compression pump 19 is out of service, cause adjustable column 1 rapid decline under deadweight and 10 effects of keying spring to be closed because the water pressure of high drive water pipe 24 reduces (the safety check 23 reverse high pressure waters of blocking high sound zone system) suddenly, thereby realized the automatic cut-out of high district backwater.At this moment, because intake pipe 3 has sealing drum 12, high sound zone system is high more, and water pressure is big more, and compressing seal ring 14 is tight more, can guarantee to close watertight.
As seen, the utility model utilizes the waterpower self-characteristic dexterously, utilizes the variation in pressure of safety check 23 front ends, has realized current automatic unlatching forward, turn-offs rapidly, and sealing is tight; Utilize relief frame 17 successfully to realize decompression, voltage stabilizing.Obviously, utilize the various waterpower reclosers of this basic principle manufacturing all can be widely used in the fluid piping systems such as hot water or cold water.
