Multi-channel reversing ball valve with modularized quick release mechanism

Abstract

The invention relates to the technical field of multi-channel sealing elements, in particular to a multi-channel reversing ball valve with a modular quick release mechanism, the ball valve comprising a main valve body and a pneumatic actuator. The multi-channel reversing ball valve with the modularized quick-release mechanism is formed by fixing an upper valve body and a lower valve body which are modularly designed with bolts, the installation is less limited, the external space occupied can be greatly reduced by adopting an integrated assembly mode, and the production and machining cost is reduced; a detachable middle sealing isolation transmission mechanism is fixedly connected to the interior of an external assembling sinking groove of the assembling ends of the upper valve body and the lower valve body, so that mutual blow-by during rotation of ball bodies in different intensities is avoided, and the internal sealing performance is improved; the control modes of the whole ball valve are more diversified, and the application range is wider; and an internal transmission mechanism and a sealing mechanism of the whole reversing ball valve are assembled by adopting a split structure, so that the cost for later detection and use is reduced.

Description

technical field [0001] The invention relates to the technical field of multi-channel seals, in particular to a multi-channel reversing ball valve with a modular quick release mechanism. Background technique [0002] Ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries, and occupy a pivotal position in the national economy. Ball valve and plug valve belong to the same type of valve, only its closing part is a sphere, and the sphere rotates around the centerline of the valve body to achieve opening and closing. [0003] The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to be rotated 90 degrees and a small rotational torque can be closed tightly. Ball valves are most suitable for on-off and shut-off valves. Ball valve is a new type of valve widely used. ...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an improved multi-channel reversing ball valve with a modular quick release mechanism in order to solve the problems in the above-mentioned background technology, so as to solve the problem of different channels of the current multi-channel ball valve during the rotation of the ball. Gas will cross each other between them, affecting the sealing performance, and most of them are split valve bodies. Valves with the same pressure and caliber take up a lot of space, and the casting cost is relatively high. Moreover, the balls in different valve bodies can only rotate synchronously, and cannot be controlled independently. It is also very inconvenient, and the valve bodies in different positions cannot be modularized, the installation limitations are relatively large, and the later inspection and maintenance are also very troublesome.
