Description

Anti-leakage ball valve

Technical Field

The utility model relates to a ball valve field, in particular to prevent ball valve of leakage.

Background

The ball valve is a valve in which an opening and closing member (a ball body) is driven by a valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline. The ball valve is divided into: pneumatic ball valves, electric ball valves, manual ball valves. The ball valves are classified according to functions: bypass valve: the ball valve is opened normally in still water, so a bypass valve is arranged to firstly carry out flat pressing, namely, two sides are filled with water; air valve: when water is filled, the air is removed and the float bowl is automatically closed; when water is drained, air is supplemented, and the buoy descends automatically; a pressure release valve: when the valve is opened and closed, pressure water between the valve and the sealing cover is discharged so as to avoid abrasion of the sealing cover; a blowdown valve: and discharging sewage at the lower part in the ball shell. When the ball valve is used, the pipeline and the valve are required to be confirmed to be washed; the operation of the valve is completed by driving the valve rod to rotate according to the input signal of the actuating mechanism: when the valve rotates for 1/4 circles (90 degrees) in the forward direction, the valve is closed, and when the valve rotates for 1/4 circles (90 degrees) in the reverse direction, the valve is opened; when the direction of the actuating mechanism indicates that the arrow is parallel to the pipeline, the ball valve is in an open state; when the indication arrow is vertical to the pipeline, the ball valve is in a closed state.

The sealing ring arranged at the joint of the ball valve and the pipeline is easy to deform and harden in the use process of the existing ball valve, and a gap can exist between the deformed and hardened sealing ring and the flange plate arranged on the pipeline, so that the joint of the ball valve and the pipeline is easy to leak finally.
