Novel lock valve

Abstract

The invention provides a novel lock valve and belongs to the technical field of valve manufacturing. The novel lock valve solves the problems of inconvenient use, short service life and the like of the conventional lock valves and comprises a valve body, a valve rod, a valve core and a handle, wherein an inner end of the valve rod is positioned in the valve body and is connected with the valve core; an upper part of the valve body is provided with an upper port which is communicated with the inner chamber of the valve body; a cylindric clamp base is connected with the inside of the upper port; the outer end of the valve rod is positioned in a chamber between the clamp base and the valve body; a blocking piece which is partially extended out of a side part of the clamp base is arranged on the clamp base; a positioning notch is formed on the inner side of the upper port of the valve body; the blocking piece is embedded in the positioning notch; a magnetic mechanism is arranged between the clamp base and the handle; and when the handle is arranged on the clamp base, the blocking piece can be driven out of the positioning notch under the action of the magnetic mechanism. The novel lock valve has the advantages of convenient use, high safety, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of valve manufacturing and relates to a valve, in particular to a novel valve with a lock. Background technique [0002] Valves with locking devices are widely used in water management industry, landscaping department, property management department and HVAC industry. For example, Chinese patent literature discloses a lock valve and its opener [application number: 200420067420.3; authorized announcement number: CN2716605Y]. valve. Although the structures of other valves with locks are different, most of them also adopt mechanical lock bodies like the above-mentioned patents, which need to be opened with a special key. Although this method is relatively safe and reliable, when a large number of valves with locks are installed, because the special keys corresponding to each valve cannot be used universally, it is inconvenient for the custodian to carry all the special keys, and it is necessary to check the s...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned lock valve can use magnetism to complete the opening and closing of the valve, it is inconvenient to make the position of the magnet in the key differ from the position of the magnetic pin by 90 degrees.

When in use, it is necessary to turn the handle position to confirm that the magnetic pin is retracted into the nest to open the valve. The opening is not direct, and the valve cannot be opened and locked immediately. It cannot be supported by the spring and sinks into the nest, the valve cannot be closed, and the service life is short
