Problems solved by technology

[0003] The existing four-way ball valves all drive the valve stem to rotate by turning the handle, and then realize the function of adjusting the flow direction of the medium, but the angle of adjustment is not easy to control, and water leakage is prone to occur, and in normal operation, misoperation often occurs , because the inside of the four-way ball valve cannot be seen, the valve stem may be reversed and the device may be damaged, so we propose a four-way ball valve operating mechanism that can avoid misoperation to solve the above-mentioned problems

Abstract

The invention belongs to the field of four-way ball valves, particularly relates to a four-way ball valve operating mechanism capable of avoiding misoperation, and provides the following scheme aiming at the problems that when an existing four-way ball valve works normally, misoperation often occurs, a valve rod is reversely rotated and a device is damaged due to the fact that the situation in the four-way ball valve cannot be seen. The valve comprises a valve body and two semi-cylindrical shells, a valve rod is arranged in the valve body, the top of the valve rod extends to the position above the valve body, the four side faces of the valve body are fixedly connected with communicating connecting pipes, and one end of each connecting pipe is fixedly connected with a flange. The connecting rod can only move clockwise along the first vertical groove, the first transverse groove, the second vertical groove and the second transverse groove in sequence and cannot move reversely, so that misoperation is avoided, the semi-cylindrical shell can be disassembled easily through the fixing assembly, and maintenance and replacement of the semi-cylindrical shell are facilitated.

Description

technical field [0001] The invention relates to the technical field of four-way ball valves, in particular to a four-way ball valve operating mechanism capable of avoiding misoperation. Background technique [0002] The "LL" type four-way ball valve only needs to operate the wrench or the actuator to turn the ball 90 degrees, and can switch the flow direction of the two media at the same time, which is convenient and fast, and realizes the effect of one valve with multiple functions. [0003] The existing four-way ball valves all drive the valve stem to rotate by turning the handle, and then realize the function of adjusting the flow direction of the medium, but the angle of adjustment is not easy to control, and water leakage is prone to occur, and in normal operation, misoperation often occurs , because the inside of the four-way ball valve cannot be seen, the valve stem may be reversed and the device may be damaged, so we propose a four-way ball valve operating mechanism ...
