Abstract
The utility model relates to a locking device for valve which mainly comprises a stop plate, an inner cover, an outer cover, a sliding block, a lower magnet strip and a steel ball. A valve rod of the valve body is locked due to the location of the steel ball, thereby achieving the locking of the valve. The sliding block is disengaged from the steel ball under the magnetic force of the lower magnet strip and an upper magnet strip in tool body to open the valve to realize the opening. The locking device 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 on the valve body, it is characterized in that said locking device, block valve body by the steel ball that is arranged on device inside, and reach the purpose of Locked valve, during unlatching, make on the slide blocks by magnetic force and to move, pressure spring moves upward, and slide blocks and steel ball are broken away from, be that locking device and valve rod 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 2, locking plate 3, interior cover 4, steel ball 5, overcoat 6, slide blocks 7, down magnetic stripe 8, spring 9, go up magnetic stripe 10, tool body 11, valve rod.
All kinds of valves are as long as at valve rod upper end processing one circular arc type groove, can use this locking device.Structural drawing when accompanying drawing is Locked valve, this locking device is made up of multiple metal or non-metallic member, locking device is by the locking plate 2 that is fixed together, interior cover 3, overcoat 5, slide blocks 6, following magnetic stripe 7, steel ball 4 is formed, and locking device is connected and fixed by steel ball 4 positioning actions and valve rod 11, thereby locking valve body 1 reaches the purpose of locking.During unlatching, last magnetic stripe is arranged in the opener body, the N of last magnetic stripe, the S utmost point corresponding respectively S, the N utmost point of magnetic stripe down, make on the slide blocks by magnetic force and to move, pressure spring 8 moves upward, and breaks away from steel ball to slide blocks, be that locking device and valve rod are thrown off, thereby valve body is opened and closed.
The inner characteristic of this locking device is by the steel ball positioning action, to realize the locking states of valve body, and reach the purpose of Open valve by magnetic force, 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 valve locking device, this device is formed by being fixed together interior cover, slide blocks, following magnetic stripe, overcoat and steel ball, it is characterized in that steel ball puts in being fixed on, and interior cover connects and contains the slide blocks of magnetic stripe down, is provided with spring between slide blocks and the overcoat.
2, locking device according to claim 1 is characterized in that being connected with valve rod by the steel ball positioning action, and two bodies are integrated, can not separate, thus Locked valve; During unlatching, the magnetic force by last magnetic stripe and following magnetic stripe makes slide blocks and steel ball disengaging, thus Open valve.
