Description
[technical field]
The present invention relates to machinery valve field, a kind of specifically novel manual diaphragm valve.
[background technology]
Diaphragm valve is a kind of block valve of special shape, and most outstanding feature is diaphragm lower body inner cavity and top
Valve deck inner cavity separates, and not only ensure that the pure of working media, while makes to be located at valve deck, valve rod and flap above diaphragm etc.
Part by dielectric corrosion, does not eliminate packing seal structure, and will not generate medium leakage.Using diaphragm made of soft material
Piece, leakproofness are preferable.The closing of diaphragm valve moves up and down what is realized with being opened by control diaphragm, therefore its service life takes
Certainly in the fatigue performance of diaphragm.
Referring to Fig. 1, at present, diaphragm valve structure mainly has valve body, valve deck, handwheel, valve rod, spool, diaphragm, and handwheel passes through
Hand wheel nut is connect with valve rod, there is externally threaded valve rod to be connect with the threaded hole at top that valve deck raises up, stem bottom
It is connect with spool, diaphragm is connected on spool, valve body is bolted with valve deck, and operation principle is：When pressure medium into
Enter valve control chamber, by controlling hand wheel rotating, band ovable valve stem rotates, can control valve so as to which diaphragm be driven to move up and down
Opening and closing.
China patent CN201420715153.X discloses a kind of diaphragm valve simple in structure, easy to assembly, but due to
Valve rod, using snap fit, causes metal friction to generate iron pin, causes have damage to diaphragm, reduce diaphragm and use with spool
Service life, it is understood that there may be false stroke phenomenon causes performance accuracy poor.And diaphragm fails to be bonded well with valve body sealing surface,
Sealing performance is not strong, there is circulation dead angle in the intake channel and exit passageway of valve body.
[invention content]
It is an object of the invention to solve the deficiencies in the prior art, a kind of novel manual diaphragm valve is provided, solves diaphragm
With spool metal friction occurs valve for valve rod in use, generates iron pin, reduces diaphragm service life, and there is false stroke
Phenomenon leads to problems such as performance accuracy poor.
To achieve these goals, a kind of novel manual diaphragm valve is designed, includes valve body, valve deck, stop nut, hand
Wheel, valve rod, spool, thrust ball bearing and diaphragm, the handwheel are connect by handwheel screw with valve rod, the valve rod and limiting
The threaded hole connection of nut, and connect with the threaded hole at top that valve deck raises up, the spool uses screw with diaphragm
Connection, the valve body are connect by bolt with valve deck, it is characterised in that the valve rod lower end uses two with spool coupling part
Thrust ball bearing is supported fixation, the thrust ball bearing positioned at spool upper end, by the shaft shoulder of valve rod and spool upper surface into
Row axially position, when valve is closed, the thrust ball bearing work of spool upper end, positioned at the thrust ball axis of valve core opening groove location
It holds, axially position, during valve opening, valve core opening groove portion is carried out by valve core opening slot upper surface and the clamp spring on installation valve rod
The thrust ball bearing work of position.
Make diaphragm more preferable with valve body sealing surface using arc transition at neighbouring spool active tunnel wall surface on the valve body
Fitting.
The valve body is equipped with intake channel and exit passageway, curved surface mistake at the intake channel and exit passageway upper side corners
It crosses, improves the circulation of medium.
The intake channel of the valve body and exit passageway intermediate projections plane, the convex plane and the diaphragm following table
The sealed muscle in face matches, and constitutes the conducting and closing of diaphragm valve.
The present invention compared with the existing technology, the advantage is that：
1. being supported fixation to valve rod and spool by using thrust ball bearing, traditional clamping connection side is changed
Formula so that valve rod is not at friction job state with spool, avoids the generation of iron pin, improves the physical life of diaphragm, and
And false stroke phenomenon is eliminated, improve the performance accuracy of valve；
2. make diaphragm better with valve body sealing surface using arc transition at neighbouring spool active tunnel wall surface on valve body
Fitting enhances its sealing performance；
3. surface blending at the intake channel of valve body and exit passageway upper side corners, improves the circulation of medium, avoids
Circulation dead angle exists.

[specific embodiment]
The invention will be further described below in conjunction with the accompanying drawings, and the structure and principle of this novel manual diaphragm valve are special to this
It is very clearly for the people of industry.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
Presently in connection with drawings and examples, the present invention is described in more detail, and all attached drawings are simplified schematic diagram,
It only illustrates the basic structure of the present invention.
As shown in Fig. 2, a kind of novel manual diaphragm valve, including handwheel (1), valve deck (2), valve rod (3), diaphragm (4), every
Film gasket (41), valve body (5), spool (6) and thrust ball bearing (71), (72), the handwheel (1) pass through screw and valve rod (3)
Connection, handwheel (1) lower end are connect with stop nut (8) external cylindrical surface using spline, the stop nut (8) and valve rod
(3) be connected through a screw thread, by adjusting stop nut (8) valve position control bar (3) stroke, the valve rod (3) and valve deck (2) to
The threaded hole connection at the top of upper protrusion, valve rod (3) lower end uses two thrust ball bearings with spool (6) coupling part
(71), (72) are supported fixation, and the diaphragm gasket (41) is connect with diaphragm (4) by screw with core valve (6) screw,
The valve body (5) is connect by bolt with valve deck (2).
As shown in figure 3, valve rod (3) lower end and spool (6) coupling part, the thrust ball axis positioned at spool (6) upper end
(71) are held, axially position are carried out by the shaft shoulder and spool (6) upper surface of valve rod (3), when rotation hand wheel (1) closes valve, institute
