Abstract

The utility model provides a valve with a magnetic control lock, which is composed of a valve body, a valve core, a lock seat, a lock cover, a protecting cover and a key, and the lock seat, the lock cover, the protecting cover and the key are on the valve body. When the key is arranged on the utility model, a magnetic iron column in the lock cover is sucked to be off a groove on the lock seat by a magnetic iron in the key, and the lock cover and the valve core can be interlocked to rotate to open the valve when the key is rotated; when the key is disassembled, the magnetic iron column is sucked back to the interior of the groove by the magnetic iron in the lock seat, the valve is locked, and the valve can not be unlocked through other tools. The utility model is suitable for various pipelines, such as a water supply pipeline, a heat supply pipeline, etc., and has the advantages of higher reliability and damage-resistant property.

Description

Valve with magnetic controlled lock

The utility model relates to a kind of valve, particularly a kind of valve with magnetic controlled lock.

At present, various water supply, vapour, wet goods pipe valve all are directly to open, close by the outer various rotatable handle of exposed valve body, and under unmanned guard's situation, anyone can arbitrarily use.Therefore, this usual type valve is unfavorable for energy-conservation and safety control.As the municipal central heat supply work of China in recent years, in order to be able to the purpose of branch family control, plain edition lock of mechanical connection on the handle of its house lead in valve and valve body, but exist key many, easily obscure and inconvenience is managed, and anti-destructive, reliability are relatively poor.

The purpose of this utility model provides a kind of valve with magnetic controlled lock, both has been convenient to management, has higher reliability and anti-destructive again.

The utility model is realized by following technological scheme: it includes spool and valve body, has a flange plate-like lock and stretch out the place at the spool of valve body, at least be provided with a groove in the upper-end surface of lock, blind hole inner fixing device at bottom portion of groove has magnet, and the external diameter of lock is provided with the ring wall guiding groove; Hat locking closure spiral-lock is on lock, its top inner groovy is nested in the rectangle shank at spool top, and the pin hole that is placed through the locking closure sidewall with pin is to the guiding groove of lock, and locking closure and lock are and are slidingly matched, the groove of corresponding lock is provided with through hole on locking closure, and magnetic column is housed in the through hole; Hat guard shield spiral-lock is on locking closure, and its lower edge is pressed together on the locking closure underpart, with locking closure all claddings except that the protruding handle of its rectangle; The hat key buckles on guard shield, and the protruding handle of the rectangle on the locking closure is placed through in the rectangular opening of key, corresponding to the magnetic column place device in the locking closure magnet is arranged at the top of key.

The magnetism intensity of the magnet of adorning is greater than the magnetism intensity of the magnet of adorning in lock and the locking closure in the described key.Be the opposite pole placed adjacent mutually between its each magnet.

Its working principle is: when loading onto key, break away from the lock groove owing to the powerful magnetic force of the magnet in the key upwards attracts to make it the lower end surface with the magnetic column in the locking closure, screw key can make locking closure rotate with spool, can realize Open valve; After closing, take off key, this moment, the magnetic column in the locking closure was entered in the groove on the lock its lower end by the attraction in the lock; then can't make valve core rotation without this Valve key; thereby realize the reliable protection effect, and extremely be convenient to management, reach the purpose of administration of energy conservation.And have higher reliability and an anti-destructive.

The embodiment who provides below in conjunction with accompanying drawing describes in further detail the structure of the utility model.
