Technical Field

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

[0002] Anti-theft gate valves are valves used to prevent theft or illegal operation, usually used in pipeline systems or equipment. They usually have special locking or sealing mechanisms to prevent non-staff from opening or closing the valve. These valves are often used in places that require additional security protection, such as oil and gas pipelines, chemical plants and other industrial facilities.

[0003] The above-mentioned and existing related technologies often have the following defects: the anti-theft gate valve needs to be opened using a specific handle when in use, and the handle needs to be taken out when not in use to prevent the anti-theft gate valve from being accidentally touched and opened. After the handle is taken out, rainwater will accumulate at the open end of the gate valve starting column, and the rainwater will penetrate into the cavity of the anti-theft gate valve, causing corrosion to the precision parts in the cavity of the anti-theft gate valve, affecting the normal use of the anti-theft gate valve.

[0004] For this reason, we propose a theft-proof gate valve. Utility Model Content
