Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in figure 1, a kind of decompression type groove wet alarm valve, including the valve body 1 of valve pocket is provided with, set at the top of valve pocket
System pipe network connector 11 is equipped with, the bottom of valve pocket is provided with water supply network connector 12, and valve pocket inner transverse is provided with flap,
Valve pocket is divided into uuper valve chamber and lower valve chamber by flap, and the outside of the valve body 1 is provided with bypass duct 13 and compensation pipeline 14, institute
State bypass duct 13 to be provided with upper cavity pressure table 131 and connect with the uuper valve chamber, the compensation pipeline 14 is provided with water supply pressure
Power table 141 and connected with the lower valve chamber.When source pressure fluctuates or impacts, bypass duct 13 and compensation pipeline 14 can
Flap top hydraulic pressure is more than its underpart hydraulic pressure, even if system pipe network pressure is more than water supply network pressure, therefore can effectively prevent
False alarm is formed because water pressure fluctuations open flap.Shower nozzle is acted when fire occurs, sprays water and causes the water of system pipes net side
Drops, and the throttling action of bypass duct 13 and compensation pipeline 14 can not make system pipe network lateral pressure and feed pipe net side immediately
Flap is just opened and to the shower nozzle continuous water supply having turned on, implements fire extinguishing by pressure balance, this pressure differential.

Connected with the outlet conduit 15.
When fire alarm occurs, the pressure of wet alarm valve system pipes net side declines, and in the presence of pressure difference, flap is opened automatically
Open, the water of feed pipe net side flows into system pipes net side and enters moisturizing to system pipe network, and whole pipe network is in automatic sprinkling fire-extinguishing state.
Meanwhile few part water flows to delayer 171 and alarm bell by the aperture on the seat ring inside valve body 1, in certain pressure and flow
In the case of, alarm bell sends alarm sound, and pressure signal is converted into electric signal by pressure switch 172, starts fire pump and auxiliary
Help fire-extinguishing apparatus to carry out moisturizing fire extinguishing, reach the purpose of automatic sprinkling fire-extinguishing and alarm.Delayer 171 be one have water inlet and
There is water inlet the cylindrical shape tank of delivery port, lower end, are communicated with outlet conduit 15, and there is delivery port upper end, connect alarm bell.By
Wave phenomenon be present in the watering pressure of system, flap can be made moment unlatching occur, current are by groove and aperture on seat ring
Delayer 171 is initially entered, because the time of source pressure fluctuation is very short, flap will soon automatically reset (closing), so
Into the water very little of delayer 171, water can be collected by delayer 171, and by the delivery port of alarm pipeline 17 bottom
Outflow, this buffer time effect of delayer 171, avoids water flow pressure fluctuation and causes the false alarm of warning water system 173.
The filter that outlet conduit 15 is set can filter to the water for flowing into pipeline 17 of alarming, and avoid sediment from entering, block pipeline,
Cause to fail and alarm, influence to rescue speed.
The outside of valve body 1 is set respectively close to the system pipe network connector 11 and the position of water supply network connector 12
Connection groove 2 is equipped with, the connection groove 2 in a ring, and connects the place section of groove 2 and the axis perpendicular of the valve body 1,
Matching jointing clip is provided with the connection groove 2.System pipe network connector 11 is used to connect with the pipe network of system side
Connect, water supply network connector 12 is used to be connected with the pipe network of water supply side, system pipe network connector 11 and water supply network connector 12
The mouth of pipe outside set ring-shaped groove, between the mouth of pipe and the mouth of pipe can by jointing clip realize connect, it is convenient to disassembly.
As shown in Fig. 2 the jointing clip includes the two clip semi-ring shells 31 that split left and right is set, the jointing clip
Inwall both sides are respectively arranged with the embedded snap ring 32 coordinated in the connection groove 2 up and down, set inside the jointing clip
It is equipped with packing ring 33, the outer wall of the packing ring 33 and the inwall snug fit of the jointing clip, above and below the inwall of the packing ring 33
