Description

Technical Field

[0001] The invention belongs to the technical field of manual valves, and in particular relates to an anti-misoperation device suitable for handle-type valves. Background Art

[0002] A valve is a mechanical device widely used in the energy, chemical and equipment manufacturing industries. It is used to control the pressure, flow rate and flow direction of the flowing fluid medium. It is the most basic component in the pipeline system. The valve operating mechanism is mainly divided into handwheel type, handle type, gear type and sprocket type. The handle type operating mechanism is a common valve operating mechanism with a relatively simple structure. It is generally composed of a rod-shaped object and a handle. The operating torque of the handle is small and is suitable for valves with smaller diameters.

[0003] For example, in the oil, gas and water systems of various industries, there are some handle valves that need to be kept normally open or normally closed. During daily maintenance and inspection of the pipeline system, these normally open or normally closed handle valves may be accidentally touched, causing the valves to malfunction, thereby affecting the safe and stable operation of various systems and equipment. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide an anti-misoperation device suitable for handle-type valves. The device has a simple structure and is easy to install. By setting the cover on the handle-type valve, the valve in the fully open position or the fully closed position can be locked, thereby preventing the safety of various systems and equipment from being affected by accidental contact during daily maintenance of the pipeline. There is no need to operate or modify the valve, and non-destructive installation can be achieved, and the installation process does not affect the normal operation of the system and the valve.

[0005] The object of the present invention is achieved through the following technical solutions:

[0006] An anti-malfunction device suitable for a handle type valve comprises an anti-malfunction device body which is covered on the handle type valve, a mounting groove is provided at the bottom of the anti-malfunction device body, an open handle locking groove is provided on two opposite first side walls of the anti-malfunction device body, and a closed handle locking groove is provided on a second side wall located between the two first side walls;

[0007] Among them, the open handle locking groove includes an avoidance section for the pipeline to pass through and a locking section located above the avoidance section, the open handle locking groove and the closed handle locking groove are both connected to the mounting groove, the bottom of the locking section contacts the top of the valve body of the handle-type valve, and the width of the locking section and the closed handle locking groove is consistent with the handle width of the handle-type valve.

[0008] In one embodiment, an observation hole is also provided on the top of the anti-maloperation device body. Through this embodiment, it is convenient for an operator to observe the handle position of the handle-type valve.

[0009] In one embodiment, a locking hole is provided on the third side wall opposite to the second side wall, in which a locking member contacting the valve body of the handle-type valve is provided. Through this embodiment, that is, a locking member contacting the valve body is provided on the third side wall, the second side wall and the locking member jointly clamp the handle-type valve body, thereby improving the stability of the anti-misoperation device main cover on the handle-type valve body.

Through this embodiment, that is, the locking screw is threadedly connected to the locking hole, it is convenient to tighten or loosen the locking screw, thereby facilitating the tightening or removal of the anti-maloperation device.

[0011] In one embodiment, the second side wall and the third side wall, which are close to each other, are in contact with the valve body of the handle-type valve. According to this embodiment, since the valve is arranged on a continuous straight pipe and when it is in the fully closed position, the handle is perpendicular to the extension direction of the straight pipe, that is, among the four side walls constituting the mounting groove, two opposite first side walls are used for the straight pipe to pass through and to lock the handle in the fully open position, and the second side wall between the two first side walls is used to lock the handle in the fully closed position. The last third side wall in the mounting groove is in contact with the valve body to limit the anti-malfunction device body, and the second side wall is used for auxiliary limiting. Even under accidental contact with external force, the anti-malfunction device body can be prevented from deflecting, thereby preventing the handle from rotating.

[0012] In one embodiment, the width of the second side wall and the third side wall is consistent with the width of the valve body of the handle-type valve. Through this embodiment, the anti-maloperation device body covered on the handle-type valve is flush with the valve body, avoiding the second side wall and the third side wall protruding from the valve body in the horizontal direction, preventing the staff performing daily maintenance from colliding with the anti-maloperation device body, and improving the working safety of the staff.

[0013] In one embodiment, the length of the avoidance section is consistent with the valve body height of the handle-type valve. Through this embodiment, when the bottom of the locking section contacts the valve body, the bottom of the mounting groove remains flush with the bottom of the valve body, that is, while saving materials, it is ensured that the mounting groove has a sufficient contact area with the valve body, thereby providing sufficient limiting strength for the anti-maloperation device body.

[0014] The beneficial effects of the present invention are:

[0015] (1) The structure is simple and easy to install. By placing the cover on the handle-type valve, the valve can be locked in the fully open or fully closed position, avoiding accidental contact during routine maintenance of the pipeline, which may affect the safety of various systems and equipment.
