Description

C-shaped forced sealing ball valve

Technical Field

The utility model relates to a ball valve technical field, in particular to sealed ball valve is forced to C type.

Background

A ball valve is a valve in which an opening and closing part (a ball body) is driven by a valve rod and rotates around the axis of the ball valve. The ball valve has the biggest characteristic that a ball body channel and a valve body flow passage form a section of pipeline after the ball valve is completely opened, and the pipeline is the valve with the minimum flow resistance.

Meanwhile, particle impurities in a medium are easily mixed between the valve seat and the ball body in the closing process of the valve, so that the sealing performance is damaged. Due to the complex structure of the ball valve, the material cost is high, the replacement cost is high after the sealing performance of the valve does not meet the requirement, and due to the difficulty in repairing, a large amount of manufacturing raw materials are scrapped, and the waste of metal resources is serious.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an aim at: the utility model provides a C type forced seal ball valve to solve the above-mentioned technical problem that exists among the prior art.

According to the above-mentioned purpose, the basic technical scheme of the utility model is: the utility model provides a ball valve is forced to sealed to C type, includes the valve body, the valve body in be equipped with sealed core, its characterized in that: the sealing core is C-shaped spherical, the valve body is internally provided with a flow guide pipe, the flow guide pipe extends into the sealing core, and the opening and closing of the fluid in the flow guide pipe are realized through uniform stress of the contact of the sealing surfaces of the valve body and the sealing core.

Furthermore, the lower end of the sealing core is arranged on a lower supporting plate in the valve body through a supporting shaft, and a valve seat is arranged between the lower supporting plate and the sealing core.

Furthermore, valve body upper portion be equipped with the valve gap, sealed core through the movable installation of drive shaft in the valve gap, sealed core and valve gap between be equipped with the backup pad.

More specifically, the upper end of the driving shaft is connected with a driving device, and the driving device is installed on the valve cover.

Furthermore, the honeycomb duct on be equipped with the detachable and conveniently change the joint of honeycomb duct.

Furthermore, the honeycomb duct is an extrusion-resistant flexible elastic hose.

Compared with the prior art, the utility model discloses an advantage and beneficial effect:

1. the utility model discloses in order to avoid the fluid medium to get into the valve pocket inside, through making special C type spheroid, install the honeycomb duct additional simultaneously in the valve body and extend to the spheroid inside, form sealedly with the spheroid inside, make the spheroid inside with outside simultaneously sealed, avoided in opening and closing the process medium to get into the valve pocket inside, also avoided the medium to contact sealed face, thereby avoided the medium to get into the possibility in the valve pocket inside, the medium flow direction does not pass through the valve pocket in opening and closing the process, also avoided opening and closing the washing away of medium torrent to the sphere in-process, prolonged the valve life;

2. the product of the utility model can realize the quick online disassembly, maintenance and replacement of the sealing pair without special tooling through the special structural design, (the valve seat can be disassembled only by opening the valve seat by special tooling which cannot be realized by other top-mounted ball valve designs on the market at present), the sealing element can be quickly overhauled or replaced online after the valve seal is damaged, the utilization rate of valve body materials is increased, and raw material resources are saved;

3. the utility model discloses the product is through inside and outside double containment design, and the even atress of the inside and outside sealed face contact of in-process is opened to the valve, has reduced the moment of torsion, has reduced sealed face wearing and tearing.
