Abstract

The utility model discloses a differential pressure type dry type alarm valve. The differential pressure type dry type alarm valve comprises a valve body, a connecting bolt, a water supply side O-shaped sealing ring, a system side O-shaped sealing ring, a valve seat, a valve clack assembly, an anti-reset mechanism, a valve cover, bolts and a valve clack shaft, wherein the valve seat is provided with an internal sealing surface and an external sealing surface; the axle center of the external sealing surface and the axle center of the internal sealing surface are different; the distance between the external sealing surface and the valve clack is longer than that between the internal sealing surface and the valve clack; the valve seat is connected with the valve body through the bolts; a valve cover sealing pad is arranged between the valve body and the valve cover; the water supply side O-shaped sealing ring and the system side O-shaped sealing ring are arranged at the joint of the valve seat and the valve body; and the system side O-shaped sealing ring and the central axis of the valve body flange are eccentric. Compared with the prior art, the utility model has the advantages of compact structure, good sealing effect and simpleness in processing.

Description

Differential pressure type dry type alarm valve
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of differential pressure type dry type alarm valve that is used on the fire-fighting system.
Background technology
The dry type alarm valve is a kind of by-pass valve control in the automatic sprinkler system.It is to fill with Compressed Gas at its outlet side, the check valve that when air pressure is lower than certain certain value, can make water flow into water injection system automatically and report to the police.Existing dry type alarm valve is owing to the gap, junction of valve seat and valve body, and the water of water supply side and system side tends to leak into remote alarm interface, influences the use of alarm valve.In addition, valve seat in the existing dry type alarm valve and valve body syndeton are comparatively complicated, and the processing assembling is also comparatively complicated.
The utility model content
The utility model is in order to solve above-mentioned deficiency, a kind of differential pressure type dry type alarm valve to be provided.
The above-mentioned purpose of the utility model realizes through following technical scheme: a kind of differential pressure type dry type alarm valve; Comprise valve body, connecting bolt, water supply side O RunddichtringO, system side O RunddichtringO, valve seat, flap sub-assembly, anti-resetting-mechanism, valve gap, bolt, flap axle; Said valve seat has inside and outside two sealing surfaces; Different axle center with inner sealing surface of external seal face and interior sealing are far away apart from the flap axle; Said valve seat is connected with a plurality of bolts with valve body; Be provided with the valve bonnet seal pad between said valve body and the valve gap, it is characterized in that: the junction of said valve seat and valve body is provided with water supply side O RunddichtringO and system side O RunddichtringO, and said system side O closed type circle and valve flange axis are eccentric.
The utility model advantage compared with prior art is: be provided with water supply side O RunddichtringO and system side O RunddichtringO in the junction of said valve seat and valve body; Make the water of water supply side and system side can't leak into remote alarm interface; And said system side O closed type circle and valve flange axis are eccentric; The utility model compact conformation, good sealing effect, and processing is simple.
[ Description of drawings]
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1-valve body; 2-connecting bolt; 3-water supply side O RunddichtringO; 4-system side O RunddichtringO; 5-valve seat; 6-flap sub-assembly; 7-anti-resetting-mechanism; 8-valve gap; 9-bolt; 10-flap axle; 11-remote alarm interface.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed:
As shown in Figure 1; A kind of differential pressure type dry type alarm valve; Comprise valve body 1, connecting bolt 2, water supply side O RunddichtringO 3, system side O RunddichtringO 4, valve seat 5, flap sub-assembly 6, anti-resetting-mechanism 7, valve gap 8, bolt 9, flap axle 10; Said valve seat 5 has inside and outside two sealing surfaces; Different axle center with inner sealing surface of external seal face and interior sealing are far away apart from flap axle 10, and said valve seat 5 is connected with a plurality of bolts of valve body 1 usefulness, is provided with valve bonnet seal pad (not shown) between said valve body 1 and the valve gap 8; It is characterized in that: the junction of said valve seat 5 and valve body 1 is provided with water supply side O RunddichtringO 3 makes the water of water supply side and system side can't leak into remote alarm interface 11 with system side O RunddichtringO 4, and said system side O RunddichtringO 4 is eccentric with valve body 1 flange axis.
