The butterfly valve is a regulating valve with a relatively simple structure, is generally mainly used for cutting off or throttling various types of fluids such as water, various corrosive media, slurry, oil, liquid metal and the like in a pipeline, and is widely applied. The traditional rubber-lined valve body adopts a cylindrical structure, the upper shaft end is sealed and cannot be replaced or adjusted, and the shaft sleeve is easy to deform under the condition of large torsion.

Disclosure of Invention

In view of the above, the invention provides a rubber-lined valve body convenient to assemble, so as to solve the problems that the upper shaft end seal of the traditional rubber-lined valve body is closed and cannot be replaced or adjusted, and a shaft sleeve is easy to deform under the condition of large torsion.

In order to achieve the above purpose, the technical scheme of the utility model is realized like this:

the utility model provides a lining rubber valve body convenient to assembly, includes valve body, axle bed, valve body both sides all are fixed with first flange, and the flange inboard sets up on the coplanar with valve body inboard, and the inboard item center of valve body extends and forms the boss, and the axle bed includes circular axle bed, octagon axle bed, and circular axle bed one end is fixed with the second flange, the one end fixed connection of the other end and octagon axle bed, and the octagon axle bed other end and valve body fixed connection all open the shaft hole that is used for installing the valve shaft on circular axle bed, octagon axle bed, the valve body, the boss.

Further, the boss includes first boss, second boss, and first boss sets up in first flange and valve body inboard, and the second boss sets up in the inboard intermediate position of first boss, all opens the shaft hole that is used for installing the valve shaft on first boss, the second boss.

Furthermore, a transition part is arranged between the first boss and the second boss, and the transition part is obliquely arranged from the first boss to the second boss.

Furthermore, a side opening corresponding to the gland is arranged on the side wall of the circular shaft seat.

Furthermore, the second flange is provided with a groove corresponding to the gland and the side port.

Furthermore, a reinforcing plate is fixed between the octagonal shaft seat and the two first flanges.

Furthermore, the external diameter of the octagonal shaft seat is smaller than that of the round shaft seat.

Compared with the prior art, the utility model discloses following advantage has:

(1) the round shaft seat and the octagonal shaft seat are matched, so that the strength of a workpiece is improved while the assembly is facilitated, the deformation of the shaft seat caused by overlarge torsion is avoided, and the service life of the valve body is prolonged.

(2) The first boss and the second boss increase the stability of the die, the smooth finish of a cast product is obviously improved, the processing flow is further simplified, and the lining rubber is not required to be directly coated during polishing.

(3) The gland can not be controlled through the side opening, and then the replacement and the adjustment can be completed under the condition that the transmission mechanism is not disassembled.

(4) Because the strength of the octagonal shaft seat is greater than that of the round shaft seat, the outer diameter of the octagonal shaft seat is smaller than that of the round shaft seat, so that the strength is ensured, the material is saved, and the cost is reduced.
