[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves are needed in gas and liquid delivery pipelines. In life, gas tanks are mostly controlled by ball valves. The ball valves are directly controlled by the handle when in use, which is easy to cause accidents due to accidental touch or loose closure during use. Therefore, a new type of high-safety self-locking valve is designed to change the above technical defects. Utility Model Content
[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a high-safety self-locking valve, which is intended to solve the technical problem that the ball valve in the prior art is directly controlled by the handle when in use, which is easy to cause accidental touch or poor closure during use, leading to accidents.

[0005] When using the valve of the present technical solution, the pinching piece is pinched to slide the movable piece and the latch toward the folding piece, the latch slides and separates from the locking piece, the pinching piece and the folding piece are brought close to compress the spring, the folding piece is grasped to drive the valve handle to rotate, and when the valve handle is rotated to the opening slot to be closed, the pinching piece is released and the pinching piece is pushed to move the movable piece and the latch toward the locking piece under the action of the spring elastic force, the latch slides and inserts into the opening slot to fix the movable piece and the valve handle, the movable piece slides and slides with the fluorescent words displayed on its surface so that the words on its surface overlap with the visible hole and leak out, prompting the user that the valve is closed and fixed, and the valve handle is rotated to the closed position. When the closing slot is opened, release the pinch piece and the spring force pushes the pinch piece to move with the moving piece and the pin toward the locking piece. The pin slides and inserts into the opening slot to fix the moving piece and the valve handle. Due to the different depths of the closed slot and the open slot, the moving piece moves a different distance toward the locking piece. At this time, the surface of the moving piece displays fluorescent words, and the open words on its surface overlap and leak out from the visible hole, prompting the user to open and fix the valve, so as to warn and self-lock the valve handle when it is switched, avoiding the technical problem that the traditional ball valve directly controls the handle during use, which is prone to accidental touch or lax closure during use, leading to accidents.
[0006] Preferably, the outer sleeve of the spring is provided with a rubber sleeve, and the two ends of the rubber sleeve are respectively fixedly connected to the outer surfaces of the pinching piece and the folding piece. By setting the rubber sleeve, the spring is protected and the spring is prevented from being damaged by external factors.
[0007] Furthermore, the outer surface of the pinching piece is provided with anti-skid patterns. The anti-skid patterns are provided to increase the friction of the pinching piece surface and avoid the problem of hand slipping during operation by the user.
[0008] Furthermore, a limit hole is provided on the outer surface of the moving piece, a limit rod is slidably installed inside the limit hole, and the left end of the limit rod is fixedly connected to the outer surface of the valve handle. By setting the limit rod and the limit hole, the moving piece is limited, and the stability of the moving piece is increased.
[0009] Furthermore, the closed card slot and the open card slot are in a trumpet shape. By setting the closed card slot and the open card slot in a trumpet shape, the opening width of the closed card slot and the open card slot is increased, which facilitates the insertion of the latch into the closed card slot and the open card slot.
[0010] The utility model pinches the pinching piece to slide the moving piece and the latch toward the folding piece, the latch slides and separates from the locking piece, the pinching piece and the folding piece are brought close to compress the spring, the folding piece is grasped to drive the valve handle to rotate, and when the valve handle is rotated to the opening slot to close, the pinching piece is released and the pinching piece is pushed to move the moving piece and the latch toward the locking piece under the action of the spring elastic force, the latch slides and inserts into the opening slot to fix the moving piece and the valve handle, the moving piece slides and slides with the fluorescent words displayed on its surface so that the words on its surface overlap with the visual hole and leak out, prompting the user that the valve is closed and fixed, and the valve handle is rotated to the closed slot When opening, release the pinch piece and under the action of the spring force, push the pinch piece with the moving piece and the pin to move toward the locking piece. The pin slides and inserts into the opening slot to fix the moving piece and the valve handle. Due to the different depths of the closed slot and the open slot, the moving piece moves a different distance toward the locking piece. At this time, the surface of the moving piece displays fluorescent words, and the open words on its surface overlap and leak out from the visible hole, prompting the user to open and fix the valve, so as to realize warning and self-locking when the valve handle is switched, avoiding the technical problem that the traditional ball valve directly controls the handle when in use, which is easy to cause accidental touch or lax closure during use, leading to accidents.
