Abstract
The utility model relates to a locking device for valve which comprises a steel ball, a spring and a lower cover. A valve cover is locked by the location of the steel ball, and the opening and closing of a control valve are achieved by taking advantage of elastic and magnetic action. The locking device can prevent the locked valve from being freely opened by people, and the locked valve must be opened and closed by a special tool. The utility model has the advantages of convenient and persistent operation, safe and reliable locking, no damage parts, and can entirely and repetitively realize a plurality of times of locking of the locking device.
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 valve body and put outward, it is characterized in that said locking device, block the valve body overcoat, and reach the purpose of Locked valve by the steel ball that is arranged on device inside, during unlatching, make down on the traveller by magnetic force and to move, pressure spring moves upward, and steel ball is shed in the downslide post channel, be that locking device and valve body overcoat are thrown off, thereby valve body is opened or closed.
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 need not be destroyed when opening locking device once more, 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.
Among the figure: 1 valve body overcoat, 2 times bodies, 3 internal channel, 4 steel balls, 5 outer channel, 6 switch knobs, traveller on 7,8 upper sleeve bodies, 9 upper springs, magnetic stripe on 10,11 lower springs, 12 times magnetic stripes, 13 times travellers.
All kinds of valves are as long as the set upper side processes a circular arc type groove outside valve body, can use this device, structural drawing when the accompanying drawing frenulum has opener to be upper sleeve body and Locked valve, this locking device is made up of multiple metal or non-metallic member, and locking device is made up of with lower spring 11 following body of being formed 2 and the valve body overcoat that has outer channel internal channel 3, steel ball 4, following magnetic stripe 12; Switch work upper sleeve body 8 is made up of with last magnetic stripe 10 switch knob 6, last traveller 7, upper spring 9.
This locking device is to inhale principle mutually by upper and lower magnetic stripe heteropole after utilizing upper and lower body to contact with each other to produce magnetic force, steel ball enters in the internal channel, this moment, gliding mass can freely enter the valve body overcoat down, upwards the pushing switch handle makes traveller away from following body, magnetic force reduces, by the effect of lower spring elastic force traveller is moved downward, thereby steel ball breaks away from internal channel and contacts with outer channel, realize the valve locking states.
Upper and lower body is in contact with one another during unlatching, and the effect of the magnetic force that produces by upper and lower magnetic stripe makes steel ball break away from outer channel and enters into internal channel, and body moves upward Open valve thereby upper sleeve body drives down.
The inner characteristic of this locking device is, make steel ball enter into outer channel by the elastic force effect, thereby utilize the steel ball positioning action to realize the locking states of valve, and make steel ball enter into internal channel by magnetic force, reach the purpose of Open valve, and when opening this locking device, locking device need not be destroyed, can all reuse, repeatedly locking and Open valve.
Claims (2)
1, a kind of novel locking device of valve is made up of lower spring, following traveller and steel ball body, it is characterized in that said locking device blocks the valve body overcoat by steel ball, by the steel ball positioning action, two bodies is integrated, can not separate, thus Locked valve.
2, locking device according to claim 1 is characterized in that down traveller, steel ball form to descend body with lower spring, is provided with down magnetic stripe in the following traveller, and its outward edge is provided with internal channel, and steel ball can upper and lowerly slide inside and outside groove.
