Abstract
The utility model discloses a novel diaphragm valve, including entrance point upper part of the body, middle part cavity and the exit end lower part of the body, the middle part cavity is established between the entrance point upper part of the body and the exit end lower part of the body, zonulae occludens between middle part cavity and the entrance point upper part of the body, and leave the hole between middle part cavity and the exit end lower part of the body top, fixed mounting has the rubber diaphragm piece between the middle part cavity and the exit end lower part of the body, rubber diaphragm piece fixed mounting is in middle part cavity bottom, the fluid promotes rubber diaphragm piece and exit end lower part of the body discontinuous distribution's supporting seat contact through the middle part cavity from entrance point upper part of the body entering, the fluid is walked around the rubber diaphragm piece and is followed the supporting seat portion of being interrupted through flowing from the exit end lower part of the body, when the fluid backflows in the equipment pipeline, the fluid gets into the exit end lower part of the body and laminates fast and form effective sealed fluid that makes and flow out in can not following the entrance point upper part of the body through promoting rubber diaphragm piece and middle part cavity inner seal face.
Description
Technical field
This utility model is related to valve technology field, specially a kind of new types of diaphragm valve.
Background technology
Micro-open type barrier diaphragm check valve also known as One-way Plastic Valves, according to structure diaphragm type, spring, duck-beak type, umbrella-type can be divided into
And combined type etc., can be widely applied to automobile industry, medical industry, plant equipment, communication equipment, household electric appliances, food drink
The various fields such as material industry, existing barrier diaphragm check valve generally existing is let out less than forming effectively sealing under 10Kpa minute-pressures
Leakage phenomenon.
Utility model content
For problem above, this utility model provides a kind of new types of diaphragm valve, and by adjusting barrier diaphragm check valve pressure is opened
Power to realize minute-pressure under sealing, can be with the problem in effectively solving background technology.
For achieving the above object, this utility model provides following technical scheme：A kind of new types of diaphragm valve, including on entrance point
Body, middle part cavity and port of export lower body, the middle part cavity is located between entrance point upper body and port of export lower body, the middle part
Closely connect between cavity and entrance point upper body, and hole, the middle part are left between middle part cavity and port of export lower body top
Diaphragm of rubber piece is installed between cavity and port of export lower body, the diaphragm of rubber piece is fixedly mounted on middle part cavity bottom
Portion.
Used as a kind of preferred technical scheme of this utility model, the entrance point upper body and port of export lower body center are respectively positioned on
On same straight line.
As a kind of preferred technical scheme of this utility model, in jump between the diaphragm of rubber piece and port of export lower body
Formula is contacted.
Compared with prior art, the beneficial effects of the utility model are：The diaphragm valve, fluid enters logical from entrance point upper body
Cross middle part cavity promote diaphragm of rubber piece contact with the support base of port of export lower body Disjunct distribution, fluid bypass diaphragm of rubber piece from
Support base discontinuities pass through and flow out from port of export lower body, and when fluid backflows in equipment pipeline, fluid enters port of export lower body
By promoting diaphragm of rubber piece quickly to fit with sealing surface in center lumen body effectively sealing is formed so that fluid is from from entrance point
Flow out in upper body.
Description of the drawings
Fig. 1 is this utility model structural representation；
In figure：1- entrance points upper body；2- middle parts cavity；3- diaphragm of rubber pieces；4- port of export lower bodies；5- holes.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment, based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Embodiment：
Fig. 1 is referred to, this utility model provides a kind of technical scheme：A kind of new types of diaphragm valve, including entrance point upper body 1,
Middle part cavity 2 and port of export lower body 4, the middle part cavity 2 is located between entrance point upper body 1 and port of export lower body 4, it is described in
Closely connect between portion's cavity 2 and entrance point upper body 1, and hole 5, institute are left between middle part cavity 2 and the top of port of export lower body 4
State and be installed with diaphragm of rubber piece 3 between middle part cavity 2 and port of export lower body 4, during the diaphragm of rubber piece 3 is fixedly mounted on
The bottom of portion's cavity 2.
The entrance point upper body 1 and the center of port of export lower body 4 are respectively positioned on same straight line, the diaphragm of rubber piece 3 with
Contact in saltatory between port of export lower body 4.
The utility model has the advantage of：When fluid is advanced from entrance point to the port of export, diaphragm of rubber piece is pushed away by fluid
It is dynamic to contact with the support base of port of export lower body Disjunct distribution, fluid bypass diaphragm of rubber piece from support base discontinuities by and from going out
Mouth end lower body flows out, and when fluid flows back from the port of export to import extreme direction, diaphragm of rubber piece is by fluid forces and middle part cavity
Inner sealing surface is fitted to be formed effectively to seal and realizes check function, and by adjusting barrier diaphragm check valve Opening pressure diaphragm of rubber piece is caused
By fluid forces strength it is very small so as to realize minute-pressure under fast sealing, thus the micro-open type barrier diaphragm check valve is simultaneously
Function with minute-pressure, fast sealing.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit this utility model
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model
Protection domain within.
