Description
Technical Field
The utility model relates to the technical field of valves, in particular to a one-piece ball valve based on pressure balance.
Background
The ball valve, the opening and closing piece is driven by the valve rod and rotates around the axis of the ball valve. The device can also be used for regulating and controlling fluid, wherein the hard seal V-shaped ball valve has strong shearing force between the V-shaped ball core and the metal valve seat of the hard alloy for surfacing, and is particularly suitable for mediums containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the flow direction switching of the medium on the pipeline, and simultaneously can close any channel to connect the other two channels. Ball valves are used in pipelines mainly to cut off, distribute and change the flow direction of a medium, and can be tightly closed only by rotating the ball valve by 90 degrees and small rotating moment. The ball valve is most suitable for being used as a switch and a cut-off valve.
The existing ball valve sealing ring is fixed and disposable, water leakage occurs when the ball valve sealing ring is worn slightly, and the ball valve sealing ring is difficult to maintain and replace, so that the whole ball valve is scrapped; when the current ball valve is in a pipe with less water flow, the water flow only applies acting force to the lower half part of the opening and closing part when the water flow can not fully fill the diversion channel in the opening and closing part, so that the stress born by the valve body is concentrated on the lower half part of the opening and closing part, the lower half part of the sealing ring connected with the opening and closing part is more rubbed by the opening and closing part, and the sealing ring is easy to be severely worn for a long time, so that the local tightness of the sealing ring is reduced, and the service performance of the ball valve is affected.
