Problems solved by technology
The connection between the handle and the valve stem of the existing ball valve is not firm, the handle cannot drive the valve stem to rotate, which affects the normal use of the ball valve, and it is inevitable that the handle will accidentally touch the handle, causing the handle to drive the spherical valve core through the valve stem Rotate, so that the ball valve can not operate normally, for this reason, we propose an external ball valve handle fixed limit device

An externally connected ball valve handle fixing and limiting device disclosed by the present invention includes a ball valve body and a handle body. The upper end of the ball valve body is provided with a square platform, and the top of the valve stem extends through the top of the square platform, and is connected with The cross connecting rod integrally formed with it, the bottom end of the handle body is provided with a connecting cylinder sleeved on the top of the valve stem, the cross connecting rod is stuck in the cross card slot on the top end of the handle body, the end of the handle body Two sets of bolts go through the connecting cylinder and are screwed to the ring seat. A limit mechanism is provided in the L-shaped groove at the front of the square table. Several sets of snap-in slots arranged equidistantly. The connection and fixation between the handle body and the valve stem of the present invention is relatively firm and stable; the valve stem and the handle body are fixed and limited by the limiting mechanism, the operation is simple and convenient, and the phenomenon of misoperation of the ball valve through the handle is effectively avoided.
Description
Technical field [0001] The present invention relates to the field of ball valve handle fixing limit device, particularly to an external type ball valve handle fixing limit device. Background [0002] Ball valve came out in the 1950s, ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small torque can be closed tightly, ball valve is most suitable for switching, shutting off valve use. The connection between the handle of the existing ball valve and the stem is not strong, and the stem cannot be driven by the handle to rotate, affecting the normal use of the ball valve, and it is inevitable that the handle will accidentally touch the handle, resulting in the handle driving the ball spool through the valve stem, so that the ball valve cannot operate normally, for this reason, we propose an external ball valve handle fixed limit device.
