Abstract
The utility model relates to a locking device for a valve. The locking device is mainly composed of a dust-proof block, a spring, a magnetic iron, a steel ball and an inner core of a lock nut which are fixed together. An inner slot of a valve neck of a valve body is clamped through positioning action of the steel ball, and a valve rod is made not to optionally twist; consequently, the purpose that the valve is locked is achieved. The locking device can prevent a locked valve from being optionally opened by people, and the locked valve can be opened and closed only by using a specific special tool. The utility model has the advantages of convenient and durable locking and unlocking operation, safe locking, etc., the utility model is provided with no damaged part, and the utility model can be repeatedly locked for many times.
Description
The utility model relates to the new locking device of a kind of valve, is the valve locking device of a kind of novel heating (water) usefulness that designed to the inexorable trend of market economy conversion by planned economy at heating (water), especially is fit to locking and often opens or normal closed gate.
The purpose of this utility model is to overcome existing technical deficiency and a kind of new locking device is provided, this device can lock the valve of setting, in heating (water) system, adopt this locking device, can be heating (water) management work a strong safeguard is provided, can effectively stop heating (water), solve the problem of heating charging difficulty the defaulting subscriber.
The utility model above-mentioned purpose can realize by the lock-in techniques measure.
A kind of valve locking device, this locking device can be installed in the valve body valve neck, it is characterized in that said locking device, block valve body valve neck inside groove by design at the inner steel ball of device, and reach the purpose of Locked valve, during unlatching, make the magnet groove that goes out of lock by magnetic force, and the rotation opener, make steel ball break away from valve neck inside groove and to enter into inner core recessed, thereby realize the open and close of valve.
Valve locking device structure provided by the utility model is simple, and Locked valve, locked secure reliably, conveniently can prevent people's opening/shutting valve at random effectively preferably.And when opening locking device once more, need not be damaged, there is not damaged components, can all reuse, repeatedly locking and unlatching.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a plan view of the present utility model.
Among the figure: 1 lock nut shell, 2 locking slot, 3 is dustproof stifled, 4 springs, 5 inner cores are recessed, 6 magnet, 7 lock nut inner cores, 8 steel balls, 9 valve neck inside grooves, 10 valve necks, 11 lockholes.
All kinds of valves are as long as add a circular arc type groove on valve body, valve neck, it is valve neck inside groove, can use this device, structural drawing when accompanying drawing 1 is Locked valve, this locking device is made up of multiple metal or non-metallic member, and this locking device is made up of dustproof stifled, the magnet that is fixed together, lock nut shell, lock nut inner core, spring.
During locking opener is aimed at lockhole, depress dustproof stifled, by magnetic attraction magnet, make the magnet groove that goes out of lock, rotate the lock nut inner core with opener, rotate to an angle, make steel ball be retracted into by the lock nut shell that inner core is recessed puts into the valve neck with lock nut, rotate back to original position, magnet is inserted in the locking slot, and inner core and shell can not be relatively rotated, and by the lock nut inner core steel ball is headed into valve neck inside groove and block valve body, extract opener dustproof stifled use to move by elastic force set back realization valve locking-valve.
During unlatching, with opener depress dustproof stifled after, rotate opener, and drive inner core and rotate to an angle, it is recessed to make steel ball return inner core, pulls up opener and takes lock nut out of, realizes valve opening.
The inner characteristic of this locking device is by the steel ball positioning action, blocks valve body valve neck, thereby realizes locking states, and reaches the purpose of opening/shutting valve by magnetic force and elastic force effect.And when opening this locking device, locking device need not destroyedly can all reuse, repeatedly locking and Open valve.
Claims (2)
- The locking device of 1 one kinds of valves, this device is made up of the magnet that is fixed together, steel ball, lock nut inner core, dustproof blocking up with spring, it is characterized in that magnet and steel ball are connected on the lock nut inner core with different azimuth, for dustproof stifled, dustproof blocking up has spring between the lock nut inner core.
- 2 locking devices according to claim 1 is characterized in that magnet is positioned at lock nut inner core inboard; Steel ball is positioned at the lock nut inner core outside.
