Abstract
The invention belongs to the field of valves. A vacuum breaker valve comprises a pneumatic valve. The vacuum breaker valve is characterized in that: a pilot electromagnetic valve and two quick exhaust valves are arranged on the pneumatic valve, the interfaces (A) of the two quick exhaust valves are communicated with the pressure cavity of the pneumatic valve respectively, the interfaces (P) of the two quick exhaust valves are connected to the interface (A) of the pilot electromagnetic valve together by using a guide pipe respectively, and the pressure port of the pilot electromagnetic valve is connected with a pressure gas source. The vacuum breaker valve solves the technical problems that emission of gas in the pressure cavity of the pneumatic valve is accelerated and the valve is quickly opened within 0.4 second.
Description
Technical field:
The invention belongs to valve field, particularly about export the vacuum breaker valve of vacuum phenomenon in the nuclear power station recirculating cooling water system in order to destruction seawater circulating water pump.
Background technique:
The recirculating cooling water system of nuclear power station is in dead electricity or when barrier is stopped transport for some reason, need in time to the vapour condenser air feed, to destroy the vacuum in seawater circulating water pump outlet port, but under normal circumstances, require to close the air feed path that this leads to vapour condenser again, and general valve, for example pneumatic valve is excessive because of its pressure chamber volume, can't reach the requirement with the open valve of intracavity gas emptying in 0.4 second.
Summary of the invention:
The object of the present invention is to provide a kind of vacuum breaker valve, solve and quicken gaseous emission in the pneumatic valve pressure chamber, make the technical problem of valve fast quick-opening valve in 0.4 second.
The technological scheme that the present invention solves the problems of the technologies described above is:
A kind of vacuum breaker valve, comprise pneumatic valve, it is characterized in that: this pneumatic valve is provided with a guide electromagnetic valve and two rapid escape valves, (A) interface of these two rapid escape valves is connected with the pressure chamber of this pneumatic valve respectively, (P) interface of these two rapid escape valves is connected this guide electromagnetic valve (A) interface jointly with conduit respectively, and the pressure port of this guide electromagnetic valve is connected with pressure gas source.
The present invention makes gas circuit unblocked in order to obtain the clean gas source medium, also is provided with filtering pressure reducing valve before guide electromagnetic valve, and the suction port of this filtering pressure reducing valve is connected with pressure gas source, and its air outlet links to each other with conduit with the pressure port of guide electromagnetic valve.
When the present invention is in normal working in system, the pressed gas of source of the gas enters from the filtering pressure reducing valve suction port, after filtration decompression back by the electric guide electromagnetic valve that be open state enters the pressure chamber of pneumatic valve, throttle down by the path of rapid escape valve.When system breaks down stoppage in transit or dead electricity; the guide electromagnetic valve dead electricity is closed; cut-out pressure source of the gas flow channel; rapid escape valve is opened; pressed gas in the pneumatic valve pressure chamber discharges jointly by two rapid escape valves and guide electromagnetic valve; finish general pneumatic valve and can not in 0.4 second, open the task of valve, in time destroyed the vacuum of exit of pump when circulating water pump is shut down, avoided the requirement of system damage.And rapid escape valve, pilot solenoid valve and filtering pressure reducing valve are existing procucts, and therefore, the existing fast quick-opening valve of the present invention has again is convenient to the advantage of making and installing.
Description of drawings:
Fig. 1 is a plan view of the present invention.
Fig. 2 is that A among Fig. 1 is to view.
Fig. 3 is a schematic diagram of gas circuit of the present invention.
Embodiment:
See also illustrated in figures 1 and 2ly, the present invention comprises pneumatic valve 1, and the adpting flange 12 of these pneumatic valve 1 usefulness valve body 11 both sides is installed in the highest point of vapour condenser outer pipe in the nuclear power station recirculating cooling water system.The pressure chamber 13 of this pneumatic valve 1 is positioned at valve body 11 tops, and the shell of this pressure chamber 13 is provided with two rapid escape valves 3 and a guide electromagnetic valve 4 that is electrically connected and locks with sea water circulating pump.(A) interface of these two rapid escape valves 3 is connected with an air inlet/outlet of pressure chamber 13 respectively, and (P) interface of two rapid escape valves is connected with pilot solenoid valve (A) interface jointly with conduit respectively.
For making gas medium cleaning from pressure gas source, the present invention also is provided with filtering pressure reducing valve 2, this filtering pressure reducing valve 2 also is fixed on pressure chamber 13 shells of pneumatic valve 1, the suction port 21 of this filtering pressure reducing valve 2 links to each other with pipeline with pressure gas source, and its air outlet links to each other with pipeline with the pressure port of pilot solenoid valve 4.
When above-mentioned vacuum breaker valve gets electric proper functioning at the nuclear power station recirculating cooling water system; the air of pressure gas source enters from the suction port 21 of filtering pressure reducing valve 2; enter after the decompression after filtration the electric guide electromagnetic valve that is on state 4 backs after the pressure chamber 13 that two rapid escape valves 3 enter pneumatic valve 1 promotes the flap throttle downs; cut-out is to the path of recirculating cooling water system vapour condenser air feed; in case the recycle pump of this system hinders for some reason or dead electricity when shutting down; lose and to close be electrically connected guide electromagnetic valve 4 dead electricity of lock of recycle pump; rapid escape valve 3 is opened; pressed gas in pneumatic valve 1 pressure chamber 13 discharges jointly by two rapid escape valves 3 and guide electromagnetic valve 4; make this pneumatic valve 1 in 0.4 second, finish out valve events; open the path that this recirculating cooling water system leads to the gas condensating device air feed, to break the vacuum of circulating water pump inlet.
