Abstract

The invention relates to a lock, in particular to a lock for a stop valve on a pipeline. The lock comprises the stop valve, a lock body, a lock handle integrated with the lock body and a lock beam, the lock body and the lock handle are respectively provided with a lock body hole and a lock handle hole which are parallel to each other, one end of the lock body is provided with a key hole, the lock beam is provided with lock beam grooves, and the lock body hole is internally embedded with movable positioning screws. The lock beam is provided with the lock beam grooves which are mechanically connected, and the lock body hole is internally embedded with the movable positioning screws which are mechanically connected. The lock has simple structure and convenient installation, the locking height of the lock beam is adjustable to be applicable to valves of different specifications, and the lock has wide application scope. The structure of multiple lock beam grooves realizes the aim that the same lockset with the lock is used in valves of different specifications, the generality is strong, and the lock beam has different locking heights, thereby realizing the aim of being used in stop valves of different specifications.

Description

Technical field: [0001] The invention relates to a lock, in particular to a lock used on a pipeline shut-off valve. Background technique: [0002] At present, the known pipeline shut-off valves usually need to be locked for safety management in places such as oil depots, oil fields, heating stations, water supply fields, gas stations, and chemical plants. The traditional lock is a chain lock. Its main defect is that the length of the chain lock is fixed, and there may be a margin when using it. It is not easy to lock, and it is easy to be picked, and its safety performance is poor. At present, the locks specially used on the stop valve generally have the problems of heavy structure, poor flexibility, complicated opening, and easy damage and prying. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned existing products, and provide a new shut-off valve lock, a kind of adjustable shut-off valve lock. [000...
