Mechanical valve locking device with dual-protection function

Abstract

The invention discloses a mechanical valve locking device with a dual-protection function. The mechanical valve locking device comprises a magnetic unlocking sleeve, a valve rod, an openable-closable open-ended cavity, a limiting clamp spring and a valve cover, wherein the openable-closable open-ended cavity is arranged above the valve cover; the valve rod is movably connected to the bottom of the openable-closable open-ended cavity; a clamp spring groove is embedded in the inner lower part of the valve cover; the limiting clamp spring is mounted inside the clamp spring groove; the valve rod is arranged inside the limiting clamp spring in a penetrating manner; a ring-shaped limiting table is mounted above the clamp spring groove; two limiting clamp tables are symmetrically arranged above the outer part of the valve cover; a plurality of locking hole grooves are symmetrically arranged at the outer circumferential part of the valve rod; locking holes are arranged at the positions, corresponding to both limiting clamp tables, on the inner side of the valve rod; two locking steel magnets are symmetrically arranged between the locking holes and the locking hole grooves correspondingly; reset elastic parts are symmetrically arranged between the locking steel magnets and the locking holes; and unlocking steel magnets are mounted between the magnetic unlocking sleeve and the locking holes. The mechanical valve locking device disclosed by the invention has an effective anti-theft function; the application scope is relatively broad; the flexibility is high; and the economic and social benefits are extremely high.

Description

technical field [0001] The invention relates to the field of mechanical valves, in particular to a double-protection mechanical valve locking device. Background technique [0002] In the existing magnetic locking valves, usually in order to meet the needs of mass production, the magnetic locking mechanism and the unlocking mechanism of the magnetic key are generally designed as a common structure, that is, they are all located on the 90-degree end wall between the upper bonnet and the bonnet. There are upper and lower lock holes corresponding to each other on the body, and a lower magnetic steel is installed between the lower lock hole and the upper lock hole, and then there is an unlocking lock at the position corresponding to the magnetic key and the upper lock hole on the upper valve cover. The upper magnetic steel, this kind of magnetic lock valve magnetic key has strong versatility, and the opening and closing protection performance is weak. During use, people can open ...

[0002] In the existing magnetic locking valves, usually in order to meet the needs of mass production, the magnetic locking mechanism and the unlocking mechanism of the magnetic key are generally designed as a common structure, that is, they are all located on the 90-degree end wall between the upper bonnet and the bonnet. There are upper and lower lock holes corresponding to each other on the body, and a lower magnetic steel is installed between the lower lock hole and the upper lock hole, and then there is an unlocking lock at the position corresponding to the magnetic key and the upper lock hole on the upper valve cover. The upper magnetic steel, this kind of magnetic lock valve magnetic key has strong versatility, and the opening and closing protection performance is weak. During use, people can open and close it as long as they have any magnetic key, so as to realize illegal opening. For the purpose, the anti-theft protection function is not in place, and it cannot really guarantee that the opening and closing of the special person is managed, and it cannot completely restrict the illegal opening of others, which is inconvenient for the management of public utilities and community properties. Therefore, it is necessary to develop a valve that can completely restrict the opening and closing of the valve. Magnetic valve locks that can also meet the needs of mass production
