Description

Technical Field

[0001] The utility model belongs to the technical field of manual valves, and particularly relates to an anti-misoperation device applicable to handle-type valves. Background Art

[0002] Valves are mechanical devices widely used in industries such as energy, chemical engineering, and equipment manufacturing. They are used to control parameters such as the pressure, flow rate, and flow direction of flowing fluid media, and are the most basic components in pipeline systems. The operating mechanisms of valves are mainly divided into handwheel type, handle type, gear type, and sprocket type, etc. The handle-type operating mechanism is a common valve operating mechanism, with a relatively simple structure, generally consisting of a rod-shaped object and a grip. The operating torque of the handle is small, and it is applicable to valves with a small diameter.

[0003] In the oil, gas, and water systems of various industries, there are some handle-type valves that need to be kept fully open or fully closed. During daily maintenance and repair of the pipeline system, these fully open or fully closed handle-type valves may be accidentally touched, resulting in misoperation of the valves, which in turn affects the safe and stable operation of each system and each device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-misoperation device applicable to handle-type valves to overcome the defects of the prior art. The device has a simple structure and is easy to install. By covering it on the handle-type valve, the valve in the fully open position or the fully closed position can be locked to avoid affecting the safety of each system and each device due to accidental touch during daily maintenance of the pipeline. There is no need to operate or modify the valve, and it can be installed without damage, and the installation process does not affect the normal operation of the system and the valve.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] An anti-misoperation device applicable to handle-type valves includes an anti-misoperation device body covered on the handle-type valve. An installation groove is opened at the bottom of the anti-misoperation device body. Open-position handle locking grooves are opened on two opposite first side walls of the anti-misoperation device body, and a closed-position handle locking groove is opened on a second side wall between the two first side walls.

[0007] Wherein, the open-position handle locking groove includes an avoidance section for the pipeline to pass through and a locking section above the avoidance section. The open-position handle locking groove and the closed-position handle locking groove are both communicated with the installation groove. The bottom of the locking section contacts the top of the valve body of the handle-type valve. The widths of the locking section and the closed-position handle locking groove are the same as the width of the handle of the handle-type valve.

[0008] In one embodiment, an observation hole is further provided at the top of the anti-misoperation device body. Through this embodiment, it is convenient for the operator to observe the position of the handle 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, and a locking member that contacts the valve body of the handle-type valve is arranged therein. Through this embodiment, that is, a locking member that contacts the valve body is provided on the third side wall, so that the second side wall and the locking member jointly clamp the handle-type valve body, improving the stability of the anti-misoperation device body covering the handle-type valve body.

[0010] In one embodiment, the locking member is a locking screw, and the locking screw is threadedly connected to the locking hole. Through this embodiment, that is, by using the method of threadedly connecting the locking screw to the locking hole, it is convenient to tighten or loosen the locking screw, facilitating the fastening or removal of the anti-misoperation device.

[0011] In one embodiment, the sides of the second side wall and the third side wall that are close to each other are both in contact with the valve body of the handle-type valve. Through this embodiment, since the valve is arranged on a continuous straight pipeline and its handle is perpendicular to the extension direction of the straight pipeline when it is in the fully closed position, that is, among the four side walls forming the installation groove, two opposite first side walls are for the straight pipeline to pass through and lock the handle in the fully open position, and the second side wall between the two first side walls locks the handle in the fully closed position. Then, by using the method that the last third side wall in the installation groove contacts the valve body, the anti-misoperation device body is limited, and the second side wall provides auxiliary limitation. Even if it is accidentally touched by an external force, the anti-misoperation device body can be prevented from deflecting, and further the handle can be prevented from rotating.

[0012] In one embodiment, the widths of the second side wall and the third side wall are the same as the width of the valve body of the handle-type valve. Through this embodiment, the anti-misoperation device body covering 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 maintenance staff during daily maintenance from colliding with the anti-misoperation device body, and improving the operation safety of the staff.

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

[0014] The beneficial effects of the present utility model are as follows:

[0015] (1) It has a simple structure and is easy to install. By covering it on the handle-type valve, the valve in the fully open position or the fully closed position can be locked, avoiding affecting the safety of each system and each device due to accidental contact during the daily maintenance of the pipeline. There is no need to operate or modify the valve, and it can achieve lossless installation without affecting the normal operation of the system and the valve.

[0016] (2) It is in full contact with the side wall of the valve body of the handle-type valve without protruding from the valve body, avoiding bumps between the daily inspection staff and the edge of the anti-misoperation device, and can provide sufficient limiting strength for itself to avoid deflection and driving the handle when there is accidental contact.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present invention will be further described below in conjunction with the drawings.

[0026] The present invention provides an anti-misoperation device applicable to a handle 200 - type valve, as Figures 1 to 3As shown in the figure, it includes an anti-misoperation device body 1 covering a handle 200-type valve. An installation groove 2 is provided at the bottom of the anti-misoperation device body 1. Locking grooves for the handle 200 are provided on two opposite first side walls 3 of the anti-misoperation device body 1, and a locking groove for the handle 200 in the closed position is provided on a second side wall 5 between the two first side walls 3.

[0027] Among them, the locking groove for the handle 200 in the open position includes an avoidance section 401 for the pipeline 300 to pass through and a locking section 402 above the avoidance section 401. The locking groove for the handle 200 in the open position and the locking groove for the handle 200 in the closed position are both communicated with the installation groove 2. The bottom of the locking section 402 contacts the top of the valve body 100 of the handle 200-type valve. The widths of the locking section 402 and the locking groove for the handle 200 in the closed position are the same as the width of the handle 200 of the handle 200-type valve.

[0028] It should be noted that the anti-misoperation device provided in this embodiment has a simple structure and is easy to install. Covering it on the handle 200-type valve can lock the valve in the fully open position or the fully closed position. As Figure 2 shown in the figure, when the handle 200-type valve is in the fully open position, or as Figure 3 shown in the figure, when the handle 200-type valve is in the fully closed position, the two opposite first side walls 3 of it can be installed on the handle 200-type valve along the extension direction of the pipeline 300. The avoidance section 401 on the first side wall 3 allows the pipeline 300 to pass through. The locking section 402 and the locking groove for the handle 200 in the closed position on the second side wall 5 are both used to limit the handle 200, avoiding affecting the safety of each system and each device due to accidental touch during the daily maintenance of the pipeline. There is no need to operate or modify the valve, and it can achieve lossless installation and the installation process does not affect the normal operation of the system and the valve.

[0029] Furthermore, an observation hole 7 is also provided at the top of the anti-misoperation device body 1, which is convenient for the operator to observe the position of the handle 200 of the handle 200-type valve.

[0030] Specifically, a locking hole 9 is provided on a third side wall 8 opposite to the second side wall 5, and a locking member in contact with the valve body 100 of the handle 200-type valve is arranged therein, so that the second side wall 5 and the locking member jointly clamp the handle 200-type valve body 100, improving the stability of the anti-misoperation device body 1 covering the handle 200-type valve body 100. The locking member is a locking screw 10, and the locking screw 10 is threadedly connected to the locking hole 9. That is, by using the method of threading the locking screw 10 into the locking hole 9, it is convenient to tighten or loosen the locking screw 10, facilitating the fastening or removal of the anti-misoperation device.

[0031] In one embodiment, the sides of the second side wall 5 and the third side wall 8 close to each other are both in contact with the valve body 100 of the handle 200-type valve.

[0032] It should be noted that since the valve is arranged on the continuous straight pipeline 300, and when it is in the fully closed position, the handle 200 is perpendicular to the extension direction of the straight pipeline 300. That is, among the four side walls forming the installation groove 2, two opposite first side walls 3 allow the straight pipeline 300 to pass through and lock the handle 200 in the fully open position, and the second side wall 5 between the two first side walls 3 locks the handle 200 in the fully closed position. Then, by the way that the last third side wall 8 in the installation groove 2 contacts the valve body 100, the anti-misoperation device body 1 is limited, and the second side wall 5 provides auxiliary limitation. Even if it is accidentally touched by an external force, the anti-misoperation device body 1 can be prevented from deflecting, thereby avoiding driving the handle 200 to rotate. It can cooperate with the locking screw 10 to lock the anti-misoperation device body 1 on the handle 200 type valve;

[0033] Furthermore, the widths of the second side wall 5 and the third side wall 8 are the same as the width of the valve body 100 of the handle 200 type valve, and the length of the avoidance section 401 is the same as the height of the valve body 100 of the handle 200 type valve;

[0034] It should be noted that in this embodiment, as Figure 2 and Figure 3 shown, both show the process diagrams of the installation of the anti-misoperation device. After the actual installation is completed, the anti-misoperation device body 1 covering the handle 200 type valve is flush with the valve body 100, avoiding the second side wall 5 and the third side wall 8 protruding from the valve body 100 in the horizontal direction. At the same time, when the bottom of the locking section 402 contacts the valve body 100, the bottom of the installation groove 2 is flush with the bottom of the valve body 100. That is, it prevents the daily maintenance staff from bumping into the anti-misoperation device body 1, improves the operation safety of the staff, and while saving materials, ensures that the installation groove 2 has a sufficient contact area with the valve body 100, provides sufficient limiting strength for the anti-misoperation device body 1, and at the same time can avoid adding too much load to the handle 200 type valve;
