Abstract
A kind of vent plug formula valve is equipped with the valve body of air bag, the air bag at least two including inner cavity, and each balloon ends are equipped with adapter tube, and adapter tube is equipped with minor valve；Each adapter tube stretches out outer take over medium of valve body and is connected to.The utility model replaces common metal material with the stronger rubber prepared material of wear-resisting, corrosion-resistant, elastic force, and structure design is simple, when valve needs to close, controlling medium can enter in airbag chamber, and when control pressure medium is greater than pipe fluid pressure in airbag chamber, air bag dilatancy is fitted closely with pipeline, blocking is tight, and fluid cannot pass through valve；When valve opening, without control medium in airbag chamber, the air bag of rubber material expands rapidly under the action of own resilient and Fluid pressure, makes unimpeded in pipeline, and fluid can flow through vent plug formula valve.
Description
Technical field
The utility model belongs to deforms the valve that fluid is truncated using air bag under the pressure of control medium, and in particular to
A kind of vent plug formula valve.
Background technique
The utility model relates to a kind of vent plug formula valve, it is related specifically to deform under the pressure of control medium using air bag
The vent plug formula valve that fluid is truncated avoids common metal valve from damaging because getting rusty or let out caused by being blocked by granular material
Leakage problem；In addition the utility model is related to the vent plug formula valve being used alternatingly using double-side gas bags, routine use side air bag
Expansion is for shutting off, and when the air bag is because of long-time expansion, recovery, generation material fatigue damage can be used another when causing explosion
Side air bag shuts off, and provides the design for replacing damaged air bag, extends minor valve service life.
Utility model content
The utility model provides a kind of vent plug formula valve, solves the made of metal valve that largely uses at present and easily gets rusty and leads
Cause gas in pipelines or liquid leakage or because the impurity in fluid blocks leakage problem caused by valve, also solves common gas
Capsule valve because balloon rupture can not normal use the problem of:
The utility model is achieved through the following technical solutions:
A kind of vent plug formula valve is equipped with the valve body of air bag, the air bag at least two, each air bag two including inner cavity
End is equipped with adapter tube, and adapter tube is equipped with minor valve；Each adapter tube stretches out outer take over medium of valve body and is connected to.
The air bag is detachably connected with adapter tube.
The air bag is made of rubber.
The utility model has the beneficial effects that the utility model is replaced with the stronger rubber prepared material of wear-resisting, corrosion-resistant, elastic force
Common metal material, and structure design is simple, when valve needs to close, control medium can enter (institute here in airbag chamber
The control medium said can be liquid and be also possible to gas), and control pressure medium is greater than pipe fluid pressure in airbag chamber
When, air bag dilatancy is fitted closely with pipeline, and blocking is tight, and fluid cannot pass through valve；When valve opening, airbag chamber
Interior without control medium, the air bag of rubber material is expanded rapidly under the action of own resilient and Fluid pressure, is made smooth in pipeline
Logical, fluid can flow through vent plug formula valve.Valve open and close repeatedly, if the one of air bag of rubber material is because for a long time
Expansion, expansion, be also easy to produce material fatigue damage, cause to burst, can enable another air bag, guarantee valve normal use, prolong
Life of valve is grown.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: 1 valve body；2 pipelines；3 bolts；4 adapter tubes；5 media adapter tube；6 minor valves；7, air bag.
Specific embodiment
Referring to Fig. 1, a kind of vent plug formula valve, the valve body 1 including inner cavity equipped with air bag 7, the air bag 7 at least two,
Each 7 both ends of the air bag are equipped with adapter tube 4, and adapter tube 4 is equipped with minor valve 6；Each adapter tube 4 stretches out outside valve body 1 and medium adapter tube 5
Connection.
The air bag 7 is detachably connected with adapter tube 4, is connected particular by bolt 3, is conveniently replaceable air bag, the row of being also convenient for
Medium in air bag out.
Valve body 1 is arranged on pipeline 2, when vent plug formula valve needs to close, only opens one of balloon ends
Minor valve 6, control medium enter the air bag cavity by control adapter tube, and the intracorporal control pressure medium of chamber is greater than in pipeline 1
Fluid pressure promotes the dilatancy under the effect of the pressure of air bag 7, until be bonded completely with 1 inner wall of valve body, 7 liang of air bag at this time
The pipeline 2 on side is unable to connection, and fluid can not play the role of shutting off by minor valve.Pressure of the air bag 7 in control medium at this time
To play the role of down that pipeline is fully sealed, repeatedly expand, restore for a long time, air bag easily forms fatigue damage, causes to burst,
The normal use for influencing vent plug formula valve, opens the minor valve 6 of another balloon ends at this time, then can be with an air bag wherein
It is enabled when damaged, in the state that minor valve is closed, air bag, and the air bag more renewed is taken out by disassembly nut, the process is not
Influence the normal use of vent plug formula minor valve.When vent plug formula minor valve needs to open, medium input, air bag cavity are not controlled
With atmosphere, Fluid pressure is greater than the pressure in airbag chamber, and air bag is in deflated state, stream under the pressure effect of fluid
Body can pass through vent plug formula valve.
