Description
[technical field]
The present invention relates to machinery valve field, specifically a kind of novel manual diaphragm valve.
[background technology]
Diaphragm valve is the block valve of a kind of specific form, and its outstanding feature is that diaphragm is lower body inner chamber
Separate with upper valve cap inner chamber, not only ensure that the pure of working media, make to be positioned at above diaphragm simultaneously
The parts such as valve gap, valve rod and flap, not by dielectric corrosion, eliminate packing seal structure, and will not produce Jie
Matter leaks outside.Using the diaphragm that soft material is made, sealing is preferable.The closedown of diaphragm valve and unlatching are logical
Crossing and control what diaphragm up and down motion realized, therefore its life-span depends on the fatigue performance of diaphragm.
Seeing Fig. 1, at present, diaphragm valve structure mainly has valve body, valve gap, handwheel, valve rod, spool, barrier film
Sheet, handwheel is connected with valve rod by hand wheel nut, has the top that externally threaded valve rod raises up with valve gap
Screwed hole connect, stem bottom is connected with spool, and connection diaphragm on spool, valve body and valve gap pass through spiral shell
Tethering and connect, its operation principle is: when pressure medium enters Valve controlling chamber, by controlling hand wheel rotating, and band
Ovable valve stem rotates, thus drives diaphragm to move up and down, and can control the opening and closing of valve.
China's patent CN201420715153.X discloses a kind of simple in construction, diaphragm valve easy to assembly, but
It is owing to valve rod uses snap fit with spool, causes metal friction to produce ferrum pin, cause and diaphragm is damaged
Wound, reduces diaphragm service life, it is understood that there may be false stroke phenomenon, causes performance accuracy poor.And barrier film
Sheet and valve body sealing surface fail well to fit, and sealing property is not strong, the intake channel of valve body and exit passageway
Interior existence circulation dead angle.
[summary of the invention]
It is an object of the invention to solve the deficiencies in the prior art, it is provided that a kind of novel manual diaphragm valve, solve
Diaphragm valve in use valve rod and spool generation metal friction, produce ferrum pin, reduces diaphragm and uses
Life-span, and there is false stroke phenomenon, cause the problems such as performance accuracy difference.
To achieve these goals, a kind of novel manual diaphragm valve of design, include valve body, valve gap, spacing
Nut, handwheel, valve rod, spool, thrust ball bearing and diaphragm, described handwheel passes through handwheel screw and valve
Bar connects, and described valve rod is connected with the screwed hole of stop nut, and the screw thread at the top raised up with valve gap
Hole connects, and described spool uses screw to be connected with diaphragm, and described valve body is connected with valve gap by bolt, and it is special
Levy and be that described valve rod lower end and spool coupling part use two thrust ball bearings to be supported fixing, be positioned at
The thrust ball bearing of spool upper end, is axially positioned with spool upper surface by the shaft shoulder of valve rod, and valve closes
When closing, the thrust ball bearing work of spool upper end, it is positioned at the thrust ball bearing of valve core opening groove location, passes through
Valve core opening groove upper surface axially positions with the jump ring installed on valve rod, during valve opening, and valve core opening
The thrust ball bearing work of groove location.
Use arc transition at neighbouring spool active tunnel wall on described valve body, make diaphragm and valve seal
Preferably fit in face.
Described valve body is provided with at intake channel and exit passageway, described intake channel and exit passageway upper side corners
Surface blending, improves the circulation of medium.
The intake channel of described valve body and exit passageway intermediate projections plane, described convex plane and described barrier film
The sealed muscle of sheet lower surface matches, and constitutes conducting and the closedown of diaphragm valve.
The present invention compared with the existing technology, has an advantage in that:
1., by using thrust ball bearing to be supported fixing to valve rod and spool, change traditional card in succession
Connect mode so that valve rod and spool are not at the job state that rubs, it is to avoid ferrum pin produces, and improves barrier film
The physical life of sheet, and eliminate false stroke phenomenon, improve the performance accuracy of valve；
2. use arc transition at neighbouring spool active tunnel wall on valve body, make diaphragm and valve body sealing surface
Preferably laminating so that it is sealing property strengthens；
3. surface blending at the intake channel of valve body and exit passageway upper side corners, improves the circulation of medium,
Avoid circulation dead angle to exist.
