At.
Above-mentioned damping fluid can be the fluid media (medium)s such as water, hydraulic oil.
The course of work of the present invention:
1) closing course.The first tracheae 405 for being connected to the first driving chamber 402 connects standard atmospheric pressure, while with second
The second tracheae 406 that driving chamber 403 is connected to connects negative pressure of vacuum, drives since the atmospheric pressure in the first driving chamber 402 is greater than second
Atmospheric pressure in dynamic chamber 403, and since the circumference outer sealing of driving diaphragm is fixed on the side wall of vacuum driving room, so driving
The outer of dynamic diaphragm is fixed, and center overcomes the elastic resistance of reset spring 404 and moves down；The top of connecting rod 6 and driving
It is fixedly connected at the center of diaphragm, therefore connecting rod is moved down by the promotion of driving diaphragm, and the bottom end due to connecting rod 6 and piston diaphragm 2
Bottom be fixedly connected, so connecting rod 6 pushes the bottom of piston diaphragm 2 to move down, until the bottom wall of piston diaphragm 2 is adjacent to valve
The spherical wall surface 103 of 1 bottom of body and reach stress balance；Before the bottom of piston diaphragm 2 moves down, it is filled in damping cavity 8
Damping fluid, since the volume of damping cavity 8 increases, forms negative pressure during the bottom of piston diaphragm 2 moves down in damping cavity 8,
First check valve 302 is forced to be connected because of pressure difference, and the damping fluid in damping liquid chamber 301 is flowed into through the first check valve 302 to be hindered
It is piston diaphragm 2 by valve in Buddhist nun's chamber 8, and suffered flow resistance when damping fluid flows into damping cavity 8 from damping liquid chamber 301
The first outlet 101 and first entrance 102 of body 1 cut off buffer damping power suffered when closing.
2) opening process.With closing course on the contrary, the first tracheae 405 connection vacuum being connected to the first driving chamber 402 is negative
Pressure, while the second tracheae 406 being connected to the second driving chamber 403 connects standard atmospheric pressure, the outer of driving diaphragm 401 is fixed not
Dynamic, center moves up under the action of pressure difference in the elastic force of reset spring 404 and vacuum driving room；Connecting rod 6 is with piston
The bottom of diaphragm 2 moves up, and the curvature of cylinder side wall 201 increases, and the volume in damping cavity 8 reduces, therefore in damping cavity 8
Damping fluid overcomes second one-way valve 303 and flows back into damping liquid chamber 301, and similarly, damping fluid is back to damping fluid by damping cavity 8
Suffered flow resistance during room 301 is piston diaphragm 2 by the first outlet 101 and first entrance 102 of valve body 1
Suffered buffer damping power when conducting.
3) decompression process.When vacuum generator breaks down, the first tracheae 405 and the second tracheae 406 are turned on atmosphere
Pressure, the first driving chamber 402 is identical with the pressure of the second driving chamber 403 at this time, and diaphragm 401 no matter is driven to be located at vacuum driving room
Top or bottom, driving diaphragm 401 shift to the middle position of vacuum driving room under the action of reset spring 404, when
Driving diaphragm 401 is when being moved to the middle position of vacuum driving room, and driving diaphragm itself is approximately at nature, and piston every
The bottom of film 2 is then moved at the position contour with the axis of the first outlet 101, and first outlet 101 and first enters at this time
Mouth 102 is in half-open position, does not influence the conducting of valve body 1 when vacuum generator breaks down.
The present invention fills damping fluid, to make in the contraction of piston diaphragm by setting damping system in piston diaphragm
It moves or expands the process moved down by the effect of fluid damping, prevent the intense impact for causing piston diaphragm under vacuum action,
The service life that piston diaphragm can thus be extended, improves the reliability of vacuum diaphragm valve.
Above-described embodiment is the description of the invention, is not limitation of the invention, after any pair of simple transformation of the present invention
Scheme all belong to the scope of protection of the present invention.
