The stop valve that can prevent aqueous reflux after valve of regulation piping flow.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of stop valve, including valve body,
Bonnet, shut-off valve assemblies, check valve assembly, test valve module, joint, O-ring, nut and clip；It is provided with the valve body
Water inlet, delivery port, test valve connecting hole and stop valve valve pocket；The bonnet is threaded on valve body, valve body and bonnet it
Between sealed by O-ring, be provided with check valve assembly in the cavity of the valve body and bonnet composition, valve be threaded with bonnet
Cap, clip is provided between bonnet and bonnet；The valve inleting water mouth is threaded with joint, passes through O between joint and valve body
Type circle seals, and is threaded with nut on joint, clip is provided between nut and joint；The shut-off valve assemblies are placed in valve
On the stop valve valve pocket of body, the shut-off valve assemblies include stop valve body, valve rod, O-ring, handwheel, alignment pin, the cut-off
Valve body is threaded on valve body, and the threaded stem is connected on stop valve body, and a handwheel is provided with the valve rod,
By positioning finger setting between handwheel and stop valve body, a conical surface is provided with the valve rod, it is corresponding, it is provided with valve body
One inclined-plane, the inclined-plane on the conical surface and valve body on valve rod partner sealing pair, the gap between regulating valve stem and valve body, can be with
Control has uninterrupted by valve；The test valve connecting hole is arranged between valve inleting water mouth and stop valve valve pocket, is tested
Test valve module is installed, testing can be with direct mounting gauge on valve module, can be to valve inleting water mouth on valve connecting hole
Pressure is detected.
The utility model uses the integrated design of stop valve, check-valves, and compared with prior art, its advantage is its structure
Simply, stop valve can play a part of adjusting piping flow, and check-valves can prevent aqueous reflux, pressure can be connected on valve body
Table, the pressure in pipeline can be monitored in real time, the both ends of valve are connected with clip and nut, are connected simply, safeguard with pipeline
It is convenient.
