Description

Integral side-mounted ball valve

Technical Field

The utility model relates to a ball valve, especially a whole side dress formula ball valve.

Background

The ball valve is a main and mature valve, and is widely applied to the aspects of aerospace, petrochemical industry, long-distance pipelines, light industrial foods, buildings and the like.

The prior art has adopted whole side-mounted formula floating ball structure, and the spheroid is installed in the valve body, is provided with upper reaches disk seat and low reaches disk seat respectively in passageway import and passageway exit, and upper reaches disk seat and low reaches disk seat form sealed vice with the spheroid cooperation, and the upper reaches disk seat is provided with O shape circle and forms sealedly with the valve body, and the upper reaches disk seat is provided with the spring behind one's back and provides the pretightning force, is provided with spacing ring I before the low reaches disk seat, is provided with spacing ring II behind the low reaches disk seat, is provided with cushion and double-.

By adopting the small-caliber ball valve (DN is less than or equal to 50) with the structure, the assembly difficulty of the valve is greatly increased, and the arm width of a person is generally more than 50mm, so that an assembler can not extend a hand into the valve body for assembly and adjustment, and the assembly efficiency is lower. Meanwhile, the valve rod is not provided with a bearing, when the valve is in a closed position, the valve rod is pressed upwards by medium pressure, and the pressure between the plane of the valve rod and the plane of the connecting sleeve is increased. When the valve needs to be opened, at the moment of opening the valve, in addition to the friction force between the ball body and the valve seat surface, the friction force between the valve rod plane and the connecting sleeve plane also causes the opening moment of the valve to be increased, and the opening and the closing are hard.

SUMMERY OF THE UTILITY MODEL

In order to overcome the prior art problem, the utility model provides an integral side-mounted ball valve.

The technical scheme of the utility model, a whole side dress formula ball valve, which comprises a valve body, be equipped with the recess in the valve body, four ring-opening are equipped with in the recess, the snap ring is equipped with in the four ring-opening, be equipped with the fender circle groove on the four ring-opening, the fender circle inslot is equipped with double-deck for the hole retaining ring, be equipped with the shaft hole on the valve body, the adapter sleeve is equipped with in the shaft hole, the adapter sleeve is equipped with the valve rod, the valve body in be equipped with.

Further, the valve component comprises a clamping ring, the clamping ring connects the ball body, the valve seat II, the supporting seat and the valve seat I into a whole, a groove is formed in the upper end of the ball body, and a connecting block is arranged in the groove.

Furthermore, the sealing rings embedded on the valve seat I and the valve seat II form sealing with the ball body.

Furthermore, an O-shaped ring II and a check ring are embedded on the valve seat I, an O-shaped ring IV is embedded on the supporting seat, an O-shaped ring I is embedded on the connecting sleeve, and the O-shaped ring I, the O-shaped ring II and the O-shaped ring IV form sealing with the valve body.

Furthermore, an O-shaped ring III embedded on the valve seat II and the supporting seat form sealing.

Further, a spring is arranged between the valve seat II and the supporting seat.

Furthermore, a needle bearing is arranged between the connecting sleeve and the valve body.

The beneficial effects of the utility model are that, in wholly packing into the valve body with the valve subassembly, can effectively guarantee the sealing performance of valve, can reduce the assembly degree of difficulty of valve, improve the assembly efficiency of valve again.

The needle roller bearing is arranged between the connecting sleeve and the valve body, sliding friction is converted into rolling friction, the moment when the valve is opened can be effectively reduced, and the valve is easy to open and close.
