Problems solved by technology

[0002] In the gas pipeline system, the general valve can only function as a switch. For some high-risk industries, valves that should not be opened may be opened due to people's negligence or bad intentions, resulting in fatal safety accidents.
In response to this situation, technical personnel have also developed many tamper-resistant ball valves, but the prior art tamper-resistant ball valves either have a cumbersome transition process between the locked state and the free switch state; Tamper effect
For example, the utility model patent No. ZL98243087.6 disclosed on the patent website of the State Intellectual Property Office discloses a technical solution for an anti-disassembly bottle valve. Convenient, but less reliable structure, easy to be disassembled

Abstract

The invention discloses an anti-dismantling ball valve. The anti-dismantling ball valve comprises a valve body, a valve core, a valve rod and a handle. The valve body is provided with a hollow protruded neck. An inner cavity of the protruded neck is communicated with an inner cavity of the valve body. The valve core is installed in the valve body. The valve rod is installed in the protruded neck. One end of the valve rod is connected with the valve core. A handle body of the handle is sleeved outside the other end of the valve rod. A magnet auto-locking mechanism is installed between the handle and the other end of the valve rod. The anti-dismantling ball valve further comprises an unlocking device, wherein the unlocking device is matched with the magnet auto-locking mechanism and is used for removing the locking of the magnet auto-locking mechanism. The anti-dismantling ball valve is simple in structure, convenient to use and effective in anti-dismantling.

Description

technical field [0001] The invention relates to the field of valves, in particular to an anti-demolition ball valve. Background technique [0002] In the gas pipeline system, the general valve can only function as a switch. For some high-risk industries, valves that should not be opened may be opened due to people's negligence or bad intentions, resulting in fatal safety accidents. In response to this situation, technical personnel have also developed many tamper-resistant ball valves, but the prior art tamper-resistant ball valves either have a cumbersome transition process between the locked state and the free switch state; Tamper effect. For example, the utility model patent No. ZL98243087.6 disclosed on the patent website of the State Intellectual Property Office discloses a technical solution for an anti-disassembly bottle valve. Convenient, but the structure is less reliable, easy to be disassembled. Contents of the invention [0003] The technical problem to be s...
