Novel valve seat of single-valve-seat bidirectional sealing track ball valve

Abstract

The invention discloses a novel valve seat of a single-valve-seat bidirectional sealing track ball valve. The novel valve seat comprises a body mechanism, a first driving mechanism and a second driving mechanism. The body mechanism comprises a valve body, a ball body, a through hole, a valve rod, a first gear, a base, a reinforcing column, a sealing gasket and a rubber ring, the through hole is formed in the ball body, the valve rod is connected to the top of the ball body, the first gear is arranged in a sound insulation cover, and an air inlet is formed in the right side wall of an air storage box. According to the novel valve seat of the single-valve-seat bidirectional sealing track ball valve, a motor is arranged, when a first driving mechanism breaks down, workers can control a hydraulic cylinder to push the motor and a connecting block to be clamped upwards in a connecting housing, and therefore a second transmission shaft and a second gear can rotate under the action of the motor, then the rotating second gear can be used for pushing the first gear to drive the ball body to rotate so that opening and closing of a device can be achieved, and the internal structure of the device can be optimized conveniently.

Description

technical field [0001] The invention relates to the technical field of a single-seat bi-directional sealing track ball valve, in particular to a novel valve seat of a single-seat bi-directional sealing track ball valve. Background technique [0002] Single seat refers to a valve with only one valve body and valve core, while the two-way sealing orbital ball valve is a kind of orbital ball valve, while orbital ball valve and gate valve belong to the same type of valve, the difference is that its closing part is a ball, the ball Rotate around the centerline of the valve body to achieve opening and closing of the valve. The two-way sealed orbital ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The existing single-seat two-way sealed orbital ball valve is prone to the phenomenon that the center of the ball is adhered and blocked by pollutants during use. Then it is easy to affect its normal work. On the other hand, m...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a new valve seat of a single-seat bidirectional sealing orbital ball valve to solve the problem that the center of the sphere is easily attached by pollutants during use of the single-seat bidirectional sealing orbital ball valve proposed in the above-mentioned background technology. The phenomenon of clogging will easily affect its normal work. On the other hand, most of the existing single-seat two-way sealed orbital ball valves only have one driving mechanism. When the driving mechanism fails, it is inconvenient to open and close the device.
