Multi-magnetic core encryption burglarproof valve

Abstract

The invention relates to a multi-magnetic core encryption burglarproof valve, comprising a valve body, a valve cover, a valve rod penetrating out of the valve cover and used for controlling the opening / closing of the valve, and a valve blocking device, wherein valve blocking device comprises a lock cover connected with the valve rod through a lock pin. The multi-magnetic core encryption burglarproof valve is characterized in that the upper end face of the valve cover is provided with a plurality of lock pin base holes, the lock pin base holes are internally provided with nonelastic spring lock pins, the lower end face of the lock cover is provided with a positioning hole matched with the upper end face of the valve cover, the bottom face of the positioning hole is provided with a plurality of magnetic core base holes corresponding to the spring lock pins, the magnetic core base holes are internally provided with movable magnetic cores, the magnetisms of adjacent movable magnetic cores are different, and the tops of the spring lock pins extend into the magnetic core base holes. The multi-magnetic core encryption burglarproof valve not only has simple structure but also has high valve block safety performance and good burglarproof performance.

Description

technical field [0001] The invention relates to a valve, in particular to a multi-magnetic core encrypted anti-theft valve with high safety performance. Background technique [0002] At present, the common encryption valves on the market are mostly controlled by magnetic cores, but generally only one magnetic core is installed. Using the principle of magnetic poles repelling each other, the magnetic core can push the lock pin away from the locking position, and then the wrench can be turned. Since there is only one magnetic core , Just use a common magnet to be placed outside the lock cover to open the valve lock opening and closing valve, and the valve lock safety performance is poor. Contents of the invention [0003] The object of the present invention is to provide a multi-magnetic core encrypted anti-theft valve. The device not only has a simple structure, but also has high safety performance of the valve lock and good anti-theft performance. [0004] The technical s...
