Abstract
The utility model relates to an integral type inflation valve, including the valve body of installing the stop valve, valve body inside is equipped with the gas transmission passageway that the accessible stop valve cut off, the gas transmission passageway has the pressure detection mouth through the branch road intercommunication, on air inlet, gas outlet and the pressure detection mouth of valve body respectively integrated into one piece have pressure connection, gas -charging connection, manometer interface. The utility model discloses a changing valve body inside passage structure, providing the precondition for realizing with various joint integrated into one piece on the valve body, the inflation valve of integral type is changed into to the inflation valve that will make up the formula, can avoid producing the leak source between each joint and the valve body, improves the installation effectiveness, simplify simultaneously the overall structure of inflation valve greatly, reduced the product volume, can also reduce seal part's use, practiced thrift the cost.
Description
Technical field
This utility model belongs to valve field, is specifically related to a kind of in nuclear power station use, prevents helium
The charge valve of leakage.
Background technology
As it is shown in figure 1, charge valve of the prior art is by bite type air inlet, triplet card shell type
Joint, pressure tapping, card sleeve pipe, ferrule stop valve, bite type inflatable interface group are combined
Form, between them be threaded connection or by conical surface seal realize seal.There is volume relatively
Greatly, assembling trouble, the defect that leak source is many.
Utility model content
The purpose of this utility model is to provide a kind of integral type charge valve, can cross simplification structure, reduce
Volume, reduces leak source, improves sealing property.
For achieving the above object, this utility model be the technical scheme is that and includes installing
The valve body of stop valve, described valve inner is had to be provided with the gas distribution channel that can be cut off, institute by stop valve
State gas distribution channel and be communicated with pressure detecting mouth by branch road；The air inlet of described valve body, gas outlet and
Respectively integrally formed with inlet suction port, gas-charging connection, pressure tapping on pressure detecting mouth.
This utility model has the advantages that by changing valve body internal passage structure, for reality
Now on valve body, provide precondition by one-body molded for various terminal, knockdown charge valve is changed
Become the charge valve of integral type, it is possible to avoid producing between each joint and valve body leak source, improve and install
Efficiency；Enormously simplify the overall structure of charge valve simultaneously, reduce small product size, moreover it is possible to reduce
The use of seal member, cost-effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing charge valve；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 2, including being provided with the valve body 1 of stop valve 5, described valve body 1 is internal to be set
Having the gas distribution channel that can be cut off by stop valve 5, described gas distribution channel is communicated with pressure by branch road
Detection mouth；Respectively integrally formed with entering on the air inlet of described valve body, gas outlet and pressure detecting mouth
Gas joint 2, gas-charging connection 6, pressure tapping 3, described inlet suction port 2 by with valve body 1 transition
The air inlet pipe 21 connected and the ring flange 22 being connected with air inlet pipe 21 overhanging end form；Described fill
Gas joint 6 is by the male-pipe being connected with valve body 1 and the barb joint group connected with male-pipe
Becoming, barb joint outer wall is overhead structure, can prevent the plastics being connected during inflation with gas-charging connection 6
Flexible pipe comes off.Described pressure tapping 3 is card socket；The valve seat of described stop valve 5 is with described
Valve body 1 is threaded connection: stop valve interface 4 is internal thread hole, and valve seat is male-pipe, side
Just install, good airproof performance.
Preferably, described gas-charging connection 6 is threaded dust cap 7, described dust cap 7 outer end
Connecting and have screw, described screw passes through nut check on dust cap 7；Described screw is also by drawing
Chain 8 is connected on stop valve 5, and after taking off dust cap 7, dust cap can be hanged 7 and hang over by slide fastener 8
On the valve rod of stop valve 5, convenient placement dust cap 7, it is to avoid dust cap 7 is lost.
Three-way valve body is changed into cross valve by integral type charge valve provided by the utility model, this
Sample just can be by one-body molded on valve body 1 for four joints, it is possible to avoids between each joint and valve body 1
Produce leak source, improve installation effectiveness；Enormously simplify the overall structure of charge valve simultaneously, reduce
Small product size, moreover it is possible to reduce the use of seal member, cost-effective.
