Abstract
The utility model relates to a structural improvement of ball valve. The utility model provides a ball valve that can improve service life of ball body and valve seat sealing pad and also improve work efficiency. The utility model comprises a valve body with an inlet and an outlet, a valve seat with a sealing pad is arranged above the inlet of the valve body, the ball body is arranged between the valve seat and the valve cover. The utility model is characterized in that: a guide sleeve for the ball body is arranged between the valve seat and the valve cover.
Description
Technical field:
The utility model relates to the improvement of spherical valve structure.
Background technique:
The suction slip of diaphragm pump and discharge slip all are to rely on the spherical valve open and close and carry out work, and the per minute jig frequency is more than 42 times.But there is following shortcoming in existing spherical valve: 1, when opening of valves, spheroid produces drift under the impact that slip flows, and the bump valve body makes spheroid fragile; 2, when closing valve, the drift of spheroid makes spheroid clash into the sealing gasket of valve seat, makes sealing gasket also fragile; When 3, the spheroid in the valve body produces drift, hinder flowing of slip simultaneously, reduced the volume delivery efficiency of slip.
The model utility content:
The utility model is exactly at the problems referred to above, and is provided a kind of working life of improving spheroid, valve base sealing pad, and the spherical valve that can increase work efficiency.
For achieving the above object, the utility model adopts following technological scheme, the utility model comprise have import, the valve body of outlet, the top of valve body import is the valve seat with sealing gasket, have spheroid between valve seat and the valve gap, be provided with the guide pin bushing of spheroid between its structure outline valve seat and the valve gap.
The beneficial effects of the utility model:
1, improved the working life of spheroid:
Owing between valve seat and valve gap, be provided with the guide pin bushing of spheroid, define spheroid and only can in the guide pin bushing of spheroid, move; Avoid slip to impact, make spheroid drift bump valve body, and damaged spheroid, thereby improved the working life of spheroid;
2, improved the working life of sealing gasket:
Owing between valve seat and valve gap, be provided with the guide pin bushing of spheroid, define spheroid and only can in the guide pin bushing of spheroid, move; Avoid slip to impact, make spheroid drift bump sealing gasket, and damaged sealing gasket, thereby improved the working life of sealing gasket;
3, increase work efficiency:
Owing between valve seat and valve gap, be provided with the guide pin bushing of spheroid, define spheroid and only can in the guide pin bushing of spheroid, move; Avoid slip to impact, make the spheroid drift, thereby slip is passed through from spherical valve of the present utility model smoothly, improved the working efficiency of spherical valve of the present utility model.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of guide pin bushing;
Fig. 4 is the A-A sectional view of Fig. 3.
Embodiment:
The utility model comprise have import 1, outlet 11 valve body 2, the top of valve body 2 imports 1 is the valve seat 4 with sealing gasket 5, has spheroid 6 between valve seat 4 and the valve gap 10, is provided with the guide pin bushing 7 of spheroid 6 between valve seat 4 and the valve gap 10.
Be provided with four guide holes 12 in the side of guide pin bushing 7; So that spherical valve of the present utility model satisfies the traffic requirement of diaphragm pump.
For alleviating noise, between guide pin bushing 7 and valve gap 10, be provided with rubber cushion 8.
The top of valve gap 10 is provided with suspension ring 9; So that dismounting valve gap 10.The side of valve body 2 is provided with oil connection 3; When dismounting valve seat 4, can be oil-filled to conical valve seat 4 from oil connection 3, valve seat 4 for convenience detach.
