Description
Technical Field
The utility model relates to a hemisphere valve part field, specific saying is a hemisphere valve disk seat convenient to maintenance.
Background
The eccentric half ball valve is a novel ball valve type, and has certain advantages unique to the structure of the eccentric half ball valve, such as no friction on the switch, difficult abrasion on the seal and small opening and closing torque. This reduces the size of the actuator to be fitted. And a multi-rotation electric actuating mechanism is matched, so that the adjustment and the tight cutting of the medium can be realized. The device is widely applicable to working conditions of strict cutting requirements such as petroleum, chemical engineering, urban water supply and drainage and the like. The eccentric half-ball valve has the characteristic of large torque, and the characteristic condition determines the severity of the abrasion of the ball valve, particularly the hard sealing eccentric half-ball valve. The damaged part is mainly contacted with the sealing part, the maintenance method is basically to repair or replace the sealing part, the cost is higher, and the movable part is designed to be more convenient for maintenance.
Therefore, it is necessary to design a hemisphere valve seat which is convenient to maintain.
Disclosure of Invention
The utility model discloses broken through the difficult problem of prior art, designed a hemisphere valve disk seat convenient to maintenance.
In order to achieve the purpose, the utility model discloses a hemisphere valve seat convenient to maintenance, including the hemispheroid, the spherical crown, sealing pressure plate, the disk seat body, holding screw, a spring, a side edge cover of hemispheroid is equipped with the disk seat body, be equipped with spherical crown and sealing pressure plate between disk seat body and the hemispheroid, the spherical crown is fixed with the hemispheroid, sealing pressure plate covers outside the spherical crown, the valve body internal surface is equipped with annular holding screw recess, holding screw passes the disk seat body and blocks in holding screw recess, be equipped with the spring between the outside of disk seat body and the valve body, the lower extreme of hemispheroid adopts lower valve shaft to be connected with the bottom of valve body, adopt the valve shaft to connect between the upper end of hemispheroid and the valve gap at valve body top.
The springs are evenly distributed between the outer side of the valve seat and the valve body.
The spring is a high-tension spring.
A sealing gasket is arranged between the spherical crown and the sealing pressure plate.
The sealing gasket is a flexible gasket.
An O-shaped ring is arranged between the valve seat body and the valve body.
Compared with the prior art, the utility model adopts the eccentric crankshaft, utilizes the eccentric principle of wedging, and drives the hemisphere to rotate through the transmission mechanism, the cambered surface of the spherical crown is gradually compressed along the cambered surface of the valve seat, thereby achieving the purpose of closing; the valve seat is installed from the inner cavity of the valve body in an upper installation mode, the valve seat is limited in a ring groove which is processed in advance by a fastening screw, and meanwhile, floating allowance is reserved; the spring that the circumference distributes is equipped with on the disk seat right side, guarantees that the disk seat reliably floats.
