Detailed description of the invention
Implement to illustrate to the present invention below in conjunction with accompanying drawing.
As it is shown in figure 1, be barrier film valve closing schematic diagram.Air pressure barrier film valve includes valve body 1 and valve gap 5, and valve body 1 is provided with inlet 2 and liquid outlet 3, and valve body 1 is provided with valve gap 5, valve gap 5 and valve body 1 joint and arranges the band through hole flange of correspondence, and is connected by screw fixing.The inner chamber of valve body 1 is provided with the diaphragm 6 that rubber is made, diaphragm 6 arranges the through hole of corresponding bonnet flange, and is fixed between diaphragm 6 and valve body 1.The outward flange of diaphragm 6 is connected the air-pressure chamber 7 forming sealing with the sidewall of body cavity, connects the electromagnetic valve 8 being arranged on valve gap 5 at air-pressure chamber 7, and electromagnetic valve 8 can connect high pressure tank.When air-pressure chamber 7 is full of gases at high pressure, diaphragm 6 moves downward, and the profile size of diaphragm 6 matches with the intracavity bottom of valve body 1, makes diaphragm 6 in the state being close to valve body 1 intracavity bottom.
For preferably improving sealing effectiveness, the intracavity bottom of valve body 1 is provided with dividing plate 4, and when air-pressure chamber 7 is full of gases at high pressure, diaphragm 6 moves downward, and on dividing plate 4, profile mates with diaphragm 6 profile size.
As another technical scheme improving sealing effectiveness, projection or groove it is provided with bottom diaphragm 6, being provided with groove or projection bottom valve body 1, when air-pressure chamber 7 is full of gases at high pressure, the groove or the projection that arrange bottom projection bottom described diaphragm 6 or groove and valve body 1 match.Here projection or groove are so that can seal more closely bottom diaphragm 6 and valve body 1, prevent valve body 1 from leaking.
In above-mentioned, electromagnetic valve 8 be provided with inlet channel and exhaust passage, inlet channel and exhaust passage and connect with air-pressure chamber 7 respectively.Electromagnetic valve 8 can more preferably realize inflating air-pressure chamber 7 and aerofluxus automatization, meets production line automation and produces needs.So arranging one or more selection that both can realize valve road, this spline structure is compacter, and cost is lower, is suitable for multi-path choice needs.
In above-mentioned, valve body 1 is provided with air gauge, and described barometric measurement end stretches into air-pressure chamber 7.Air gauge can monitor the pressure in air-pressure chamber in real time, thus monitors valve opening and closing or sealing state.
Here, utilize pressurization and the decompression of gases at high pressure in air-pressure chamber 7, promote diaphragm 6 motion to realize the Guan Bi of valve and the purpose opened.When being full of gases at high pressure in air-pressure chamber 7, owing to gas pressure promotes diaphragm to move downward, diaphragm 6 fits tightly bottom valve body 1, thus closes valve.
As in figure 2 it is shown, be barrier film valve opening schematic diagram.When air-pressure chamber 7 inner high voltage gas is by exhaust passage aerofluxus, pressure reduces rapidly, and in valve body 1, fluid is due to pressure itself upwards jack-up diaphragm 6, and diaphragm 6 separates bottom valve body 1, thus realizes fluid flowing.
Here providing a kind of improvement project, i.e. valve body 1 is three-way structure, wherein has in a path and is provided with described diaphragm 6.It is of course also possible to be arranged on two or three paths to be provided with described diaphragm 6, forming blanket gas pressure chamber between diaphragm 6 and valve body 1, air-pressure chamber 7 connects the electromagnetic valve 8 on valve body 1 simultaneously.Here electromagnetic valve 8 can be banked direction control valves, is so capable of multiple air-pressure chamber superchargings or the control of decompression, thus realizes the closure or openness to valve body difference path.
