Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an anti-theft valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves and regulating valves. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems.

[0003] According to the patent with announcement number CN219549722U, an anti-theft valve is proposed. The anti-theft valve has a plum blossom-shaped valve handle. When the valve handle needs to be rotated, a special sleeve ring is required to rotate. At the same time, when the sleeve ring is sleeved on the valve handle, the second push block is inserted into the clearance groove. The second push block pushes the extrusion block to move downward, and the extrusion block squeezes the first push block to move to both sides. The first push block pushes the limit block into the sliding cavity. When the sleeve ring contacts the bottom of the clearance groove, the first push block just pushes the limit block to the intersection between the valve stem and the valve body. Only then can the valve handle be rotated, thereby achieving the effect of preventing the valve body from being opened privately.

[0004] However, the anti-theft valve can be operated by simply removing the plum blossom-shaped valve handle, which does not prevent unauthorized personnel from opening and closing the valve without authorization and does not meet the user's needs. Therefore, an anti-theft valve is proposed to solve the above problem. Utility Model Content

The limiting block 204 prevents the limiting tooth ring 203 from escaping from the first shell 201. A cover plate 205 is rotatably installed on the top of the first shell 201.

[0024] Specifically, the valve body 1 is protected by the first shell 201 and the second shell 202. When operating the valve body 1, the second shell 202 is opened to operate the valve body 1. The limit block 204 prevents the limit tooth ring 203 from escaping from the first shell 201. The two limit tooth rings 203 fix the first shell 201 and the second shell 202 to prevent unauthorized personnel from opening and closing the valve without authorization, thereby meeting the use needs of users.

[0025] In this embodiment, the locking mechanism 3 includes a worm lock core 301, one end of the worm lock core 301 passes through and extends to the outside of the first shell 201, a lock core hole is opened at one end of the worm lock core 301, a mounting seat is fixedly installed on the inner bottom wall of the first shell 201, a synchronization rod 302 is rotatably installed inside the mounting seat, a worm wheel 303 is fixedly installed on the outer surface of the synchronization rod 302, the outer surface of the worm wheel 303 is meshed with the outer surface of the worm lock core 301, and the worm lock core 301 drives the synchronization rod 302 to rotate through the worm wheel 303.

The outer surface of the synchronization rod 302 is fixedly installed with two first bevel gears 304. The outer surfaces of the two first bevel gears 304 are respectively meshed with the outer surfaces of the two second bevel gears 306. The synchronization rod 302 drives the two second bevel gears 306 and the two rotating rods 305 to rotate through the two first bevel gears 304.

[0027] Among them, the outer surfaces of the two rotating rods 305 are fixedly installed with synchronous gears 307, and the outer surfaces of the two synchronous gears 307 are respectively engaged with the opposite sides of the two limiting gear rings 203.

[0028] Specifically, the cover plate 205 is opened, and the worm lock core 301 is rotated with a key that matches the lock core hole, so that the worm lock core 301 drives the synchronization rod 302 to rotate through the worm wheel 303, and the synchronization rod 302 drives the two second bevel gears 306 and the two rotating rods 305 to rotate through the two first bevel gears 304, and the two rotating rods 305 drive the two limiting tooth rings 203 to retract into the first shell 201 through the two synchronization gears 307, so that the valve cannot be easily opened or operated in the closed state, thereby improving the anti-theft performance of the valve.

[0029] The working principle of the above embodiment is:

[0030] The valve body 1 is protected by the first shell 201 and the second shell 202. When operating the valve body 1, the cover plate 205 is opened, and the worm lock core 301 is rotated with a key that matches the lock core hole, so that the worm lock core 301 drives the synchronization rod 302 to rotate through the worm wheel 303, and the synchronization rod 302 drives the two second bevel gears 306 and the two rotating rods 305 to rotate through the two first bevel gears 304. The two rotating rods 305 drive the two limiting toothed rings 203 to retract into the first shell 201 through the two synchronous gears 307, and the second shell 202 is opened to operate the valve body 1. The limiting block 204 prevents the limiting toothed ring 203 from escaping from the first shell 201. At the same time, due to the self-locking of the worm lock core 301 and the worm wheel 303, the limiting toothed ring 203 cannot be operated from the outside.
