Detailed description of the invention
Please refer to shown in Fig. 1 and Fig. 2, it has demonstrated preferred embodiment concrete of the utility modelStructure, includes valve body 10, valve seat 21, flap 22, delayer 23, pressure switch 24 and waterPower alarm bell 25.
This valve body 10 has the intake antrum 11 and the water chamber 12 that communicate with each other, and this valve seat 21 is arranged at water outletIn chamber 12, this flap 22 is positioned at water chamber 12 and is pressed against on valve seat 21, is arranged with close on flap 22Big envelope 26, sealing cover 26 wraps the outer peripheral edges of flap 22, and sealing shroud 26 bottom centre pass through pressing plate27 installations are fixing, and in the present embodiment, described pressing plate 27 is fixed on the bottom surface of flap 22 by screw 28Center.
The tail end that this intake antrum 11 is connected with the first pipeline 29, the first pipelines 29 is connected with the first Pressure gauge30, this first Pressure gauge 30 is for showing pressure of supply water, and this water chamber 12 is connected with second pipe 31 HesThe 3rd pipeline 32, the tail end of this second pipe 31 is connected with the second Pressure gauge 33, second pipe 31 andBetween one pipeline 29, be connected with on compensation check-valves 34, the three pipelines 32 and be provided with draining valve 35, shouldOn valve seat 21, be connected with and on the 4th pipeline 36, the four pipelines 36, be disposed with pet valve 37, controlValve 38 and and filter 39, aforementioned the 3rd pipeline 32 joint test valves 37, this delayer 23 connects the 4thThe tail end of pipeline 36, this pressure switch 24 and warning water system 25 are all connected the output of delayer 23.
And, on described second pipe 31, be also provided with automatic regulator 40, as shown in Figure 2, this is automaticAdjuster 40 is by governor body 41, left side O RunddichtringO 42, piston 43, spring 44, right side ORunddichtringO 45, choke block 46 and joint 47 form.
