Description
Technical field
The utility model is related to valve fields, stop integral valve more particularly to a kind of valve.
Background technology
Valve stops an integral valve part and is flowed in itself and automatic open and close flap by medium, another for preventing medium from flowing backwards
Part is made of butterfly valve, it is a kind of automatic valve and the valve of one, main function are to prevent medium from flowing backwards, preventing manually
Pump and drive motor reversion and vessel media are released, also known as non-return valve, check valve, reflux valve and counterbalance valve, non-return
The auxiliary system that valve can also be used to be raised above system pressure to pressure therein is provided on the pipeline of supply, while butterfly valve is used
In switch pipeline, facilitate maintenance operation.
Utility model content
It is good that the purpose of this utility model is to provide a kind of simple in structure, reasonable design, easy for installation and backflow effect
Valve stops integral valve.
The technical solution of the utility model is as follows：A kind of valve stops integral valve, described including butterfly valve body and check valve body
Butterfly valve body above have a handle, one end is connected with flange, and the other end is connected with check valve body, check valve body it is another
End is connected with flange, is provided with a circle valve seat on water inlet end inner valve body wall in check valve body, is hinged with right over valve seat
One circular valve plate, is hinged with a chain immediately below valve seat, and the other end of circular valve plate lower part and chain is hinged.
It is improved as one of which, the flange, what is connect with butterfly valve body one end is loose flange, with check-valves valve
Body connection is mounting flange；Loose flange stops the integral installation and use of integral valve convenient for valve.
Preferred as one of which, the length of the chain is the 1/2-2/3 of check-valves depth；In this way, during water inlet, can prevent
Only the valve plate in check-valves is contacted with another inner wall of check-valves, influences flow.
Preferably, the circular valve plate diameter is long compared with valve seat bore；
More preferably, a circle sealing rubber ring is pasted on the contact surface of the circular valve plate and valve seat；Valve plate is compared with valve seat
Adhesive seal circle on interior path length and contact surface helps that during valve plate reflux fluid stopping sealing fluid stopping effect can be functioned well as.
Compared with prior art, the beneficial effects of the utility model are：The valve stop integral valve reasonable design, it is simple in structure,
Easy for installation and fluid stopping effect is good, while has sealing rubber ring to protect valve plate, valve plate mechanical damage, safety when being avoided that fluid stopping
Higher.

Specific embodiment
The utility model is further illustrated in the following with reference to the drawings and specific embodiments.
As shown in attached drawing 1-4, a kind of valve stops integral valve, including butterfly valve body 1 and check valve body 2,1 top of butterfly valve body
There is handle 3, one end is connected with loose flange 4, and loose flange stops the integral installation and use of integral valve convenient for valve, and the other end connects
Check valve body 2 is connected to, the other end of check valve body is connected with mounting flange 5, the valve on the inside of water inlet end in check valve body
A circle valve seat 6 is provided on body wall, 6 surface of valve seat is hinged, and there are one circular valve plates 7, and 7 diameter of circular valve plate is compared with 6 internal diameter of valve seat
It is long, circular valve plate 7 be pasted with a circle sealing rubber ring 8 on the contact surface of valve seat 6, contribute to valve plate flow back fluid stopping when can be very well
Ground plays sealing fluid stopping effect, and a chain 9 is hinged with immediately below valve seat 6, and 7 lower part of circular valve plate and the other end of chain 9 are cut with scissors
It connects；The length of chain is the 1/2-2/3 of check-valves depth, in this way, during water inlet, can prevent valve plate in check-valves and check-valves
Another inner wall contact, influences flow.
When specifically used, for example, valve stop integral valve for desk-top water supplying pump system when, valve stops integral valve and passes through flanged joint
Into water system, when flow enters system, the valve plate in check-valves is opened under water impact, and under the action of chain, valve plate begins
Eventually in half opened condition, another inner wall that will not directly contradict check-valves prevents flow, so as to which flow parallel flows, when having
When flow flows back, under hydraulic pressure effect, valve plate voluntarily close by return, due to having the buffering of sealing rubber ring and sealing function, valve
Plate will not directly hit check-valves inner wall, avoid mechanical damage, while sealing effect might as well.
It is good that the valve stops integral valve reasonable design, simple in structure, easy for installation and fluid stopping effect, while has sealing rubber ring guarantor
Protect valve plate, valve plate mechanical damage when being avoided that fluid stopping, safety higher.
Above-mentioned technical proposal only embodies the preferred embodiment of the utility model, it is impossible to be interpreted as to the utility model standard
Perhaps the limitation of range, all modification and improvement made according to the utility model, belongs to scope of protection of the utility model.
