Problems solved by technology
Conventional valve products generally only have a single performance. In a pipeline system, when multi-functional control is required, multiple types of products must be installed, which increases the cost of use and reduces production efficiency.
[0003] The existing ball valve will have friction between the ball and the sealing ring of the valve seat during the whole operation of opening and closing, resulting in poor sealing and short service life

The invention discloses a multifunctional friction-free fixed short ball valve and an operating method thereof. The multifunctional friction-free fixed short ball valve comprises a valve seat and a turbine box, wherein pressing rings are respectively arranged on the left and right ends of the valve seat, elastic components are arranged on the inner sides of the pressing rings, and switching disengagement positioners are respectively arranged on the upper and lower ends of a square sphere. When the ball valve is opened, the turbine box rotates anticlockwise so as to drive an upper valve rod, the square sphere, a lower valve rod and the switching disengagement positioners from 0 degrees to 90 degrees to be fully open; when the ball valve is closed, the turbine box rotates anticlockwise so as to drive the upper valve rod, the square sphere, the lower valve rod and the switching disengagement positioners from 90 degrees to 0 degrees to be fully closed; in the processes of opening and closing, both sides moves on the valve seat so as to disengage from the sphere under the action of the concave-convex curved surfaces of the switching disengagement positioners and the elastic components. The multifunctional friction-free fixed short ball valve has the advantages of no friction of the whole process, good sealing performance, long service life and convenience in use, media can enter from any end of the valve, and the multifunctional friction-free fixed short ball valve can be installed in any direction.
Description
technical field [0001] The invention relates to a multifunctional non-friction fixed short ball valve and an application method thereof, belonging to the technical field of ball valves. Background technique [0002] Ball valve products are in the actual use and production process of the pipeline system. There are quite a few product types in a pipeline system. The performance of the valve and the reliability of the production process play an important role, which has a relatively large impact on the production cost and production time of the enterprise. big impact. Conventional valve products generally only have a single performance. In a pipeline system, when multi-functional control is required, multiple types of products must be installed, which increases the cost of use and reduces production efficiency. [0003] The existing ball valve has friction between the ball and the sealing ring of the valve seat during the whole operation of opening and closing, resulting in po...
