Description
Valve for guarding against theft is mainly used in a kind of anti-theft device that working mediums such as gas, liquid flow in pilot line or the equipment.
The daily valve that is used for pipeline or equipment, its control section are to expose outside, and be stolen easily, dangerous under unattended situation.
The purpose of this utility model is that the control section of valve is exposed to the outer hidden repacking of carrying out, and reaches antitheft purpose.
The utility model is achieved in that it mainly is that assembling one Theft-proof stopper and bottom valve with lock is connected as a single entity.After promptly upper half part handwheel of valve being removed, above the valve gap of valve, assemble a Theft-proof stopper with lock, the square head on valve screw mandrel top is sealed with Theft-proof stopper, screw mandrel is locked in the inside, valve can't open and close under the situation of no private key like this, reach antitheft purpose, when valve need open and close, must after opening Theft-proof stopper, private key just can carry out operation element with special movable special sleeve spanner.
Great advantage of the present utility model is a good anti-theft effect, has removed handwheel, installs Theft-proof stopper and special sleeve spanner additional, and production safety is secure.
Advance an explanation below in conjunction with accompanying drawing:
Fig. 1 is the valve for guarding against theft structural representation, and Fig. 2 is the special sleeve spanner structural representation.
Accompanying drawing is explained:
1, valve body, 2, valve gap, 3, go out the packing material, 4, the sealing plug, 5, screw mandrel top square toes, 6, wire lever, 7, nut, 8, leading screw, 9, flashboard, 10, valve port, 11, valve cover screw 12, locating stud, 13, the lock pin groove, 14, the plug lid, 15, lock core, 16, pellet shot from a slingshot, 17, spring, 18, the lock core rotating shaft, 19, lock pin, 20, plectrum, 21, plug, 22, key, 23, locating slot, 24, the plug outer wall, 25, extension lever, 26, interior square hole, 27, the extension lever hole, 28, socket wrench.
As shown in Figure 1, below stuffing box packing (3), be original valve mechanism, here just needn't repeated description, more than filler (3) for improving the theft-prevention structure part, the Theft-proof stopper assembly has a plug locating stud (12) to be used to locate plug (21) by the lower end of plug outer wall (24).At the corresponding plug outer wall of plug locating stud (12) is lock pin groove (13), and its effect is a link pin (19) when plug when stretching out, and pins plug.Plug lid (14) is installed in plug outer wall upper end, can be rainproof, dust etc.There is positioning hole (13) the plug below with the locating stud corresponding section of plug outer wall.When plug was transferred, the positioning hole of plug was meshed with the locating stud of plug outer wall, plays the role of positioning.Common anti-theft door lock cylinder (15) is equipped with in the centre of plug, and lock core rotating shaft (18) below in the middle of the lock core connects plectrum (20), and the plectrum below connects link pin (13).When link pin stretches out, insert in the lock pin groove of plug outer wall, play pin and decide the plug effect.During switch valve, be equipped with the socket wrench specially adapted for it wrench in addition, the socket wrench specially adapted for it wrench assembly of Fig. 2 mainly is made of inner sleeve (28) and extension lever (25), interior square socket top (26) is with interior square hole structure, can be by constituting more than three square holes, when the needs starting gate, interior square socket is enclosed within flashboard leading screw top square toes (5) use just can.Several shapes such as extension lever (25) can the side of making, circle, extension lever (25) is to insert afterburning hole (27) to use.
When installing and using this valve for guarding against theft, plug is located by plug locating stud (12) after entering plug outer wall (24) inner chamber, key (22), lock core rotating shaft (18) drives plectrum (20), plectrum (20) drivening rod lock pin (19) stretches out and inserts lock pin groove (13), transfer to the key plug locked, otherwise the connecting rod lock pin withdraws from the lock pin groove, plug can take out.During switch valve, behind the taking-up plug special-purpose leading screw box spanner is enclosed within on the square toes of flashboard leading screw top, can carries out the switch valve operation.
