Method is usurped.
What the utility model was realized in：A kind of valve pocket above Anti-theft stop valve, including valve body, valve body, it is arranged at
Valve element and action bars in valve pocket, the valve body two ends, which are respectively equipped with water inlet and delivery port, valve body, is provided with valve port, institute
The plugging block that control valve port opening and closing are movably set with valve port is stated, the valve element lower end is installed in plugging block, in the valve pocket
Wall, which is provided with the middle of baffle ring, baffle ring and plugging block, is provided with sealing ring, and the stage casing of the valve pocket madial wall is provided with internal thread, institute
The external screw thread for being provided with and being matched with the internal thread on valve element is stated, the valve element upper surface is provided with annular recess, the operation
The snap ring matched with annular recess is provided with bar.
A kind of above-mentioned Anti-theft stop valve, the plugging block is interior cylindric, the valve element lower end card for being provided with stepped hole
In stepped hole loaded on plugging block.
Bonnet is installed above a kind of above-mentioned Anti-theft stop valve, the valve pocket, bonnet madial wall is provided with internal thread, institute
The epimere for stating valve pocket lateral wall is provided with the external screw thread matched with the internal thread.
A kind of above-mentioned Anti-theft stop valve, the bonnet upper surface is provided with what is matched with the snap ring on the action bars
Annular recess.
The utility model has the following advantages that：Anti-theft stop valve of the present utility model is by installing additional with special construction
Bonnet and plugging block, can only can just be turned on and off valve by corresponding anti-theft device, effectively prevent the illegal of valve and open
Open or close, liquid in pipeline can be effectively guarded against and illegally usurped；Bonnet can stop the entrance of debris again simultaneously, make valve not
It is easily damaged, extend the service life of stop valve.Plugging block can fully ensure that the sealing of stop valve, improve stop valve
Security performance.

Embodiment
With reference to specific embodiment, the utility model will be further described.
Embodiment 1：A kind of Anti-theft stop valve, as shown in Figure 1, 2, including valve pocket 2 above valve body 1, valve body, is arranged at valve
Valve element 3 and action bars 4 in set, the two ends of valve body 1, which are respectively equipped with water inlet 5 and delivery port 6, valve body, is provided with valve port
7, it is movably set with the plugging block 8 of control valve port opening and closing at the valve port 7, plugging block drops to after extreme lower position just can be with
Valve port 7 is blocked, plugging block 8 rises then valve port unlatching, and at this moment water inlet 5 is connected with delivery port 6.The plugging block 8 sets to be interior
There is the cylindric of stepped hole 14, in stepped hole of the lower end active card of valve element 3 loaded on plugging block, when the lower end of valve element 3 is to moving up
When dynamic, plugging block 8 is driven to move up.The inwall of valve pocket 2 is provided with the middle of baffle ring 9, baffle ring and plugging block and is provided with sealing
Circle 10, plugging block 8 is during moving up and down, and sealing ring 10 can prevent the liquid at the valve port 7 of lower section from oozing out well,
Certain cushioning effect is played during plugging block is moved up and down simultaneously, it is to avoid its structural damage.The madial wall of valve pocket 2
Stage casing be provided with the external screw thread being provided with internal thread, the valve element 3 on the external screw thread matched with the internal thread, valve element 3
Cooperate and can rise with movable valve plug with the internal thread in the stage casing of the madial wall of valve pocket 2, the upper surface of valve element 3 is provided with ring-type
The snap ring 13 matched with annular recess is provided with groove 12, the action bars 4, due on the snap ring and valve element on action bars
The annular recess of end face is one-to-one relation, so as to prevent stop valve from being stolen by other people illegal open.It is preferred that,
The top of valve pocket 2 is provided with bonnet 11, and the madial wall of bonnet 11 is provided with internal thread, and the epimere of the lateral wall of valve pocket 2 is set
There is the external screw thread matched with the internal thread, the upper surface of bonnet 11 is provided with to match with the snap ring on the action bars 4
Annular recess, the annular recess is consistent with the shape of annular recess 12 of the upper surface of valve element 3, can also be opened with action bars 4,
Bonnet 11 is installed in the top of valve pocket 2, can stop the entrance of debris, make valve element 3 not easily damaged, extend the service life of stop valve.
Operation principle：
Snap ring 13 on action bars 4 is directed at annular recess 12, rotating operation bar, valve element 3 is rotated, the external screw thread on valve element
Cooperated with the internal thread in the stage casing of valve pocket madial wall, valve element rises, the plugging block 8 of valve element lower end rises therewith, works as closure
Block rises to certain position, and plugging block upper surface touches the inwall of valve pocket 2, so that plugging block stops rising, then valve element also will
Stop rising, now, stop valve valve port 7 is opened completely.Conversely, rotating backward action bars 4, then similarly valve element 3 declines, plugging block
Decline, until the lower end of plugging block 8 is tightly pressed against on valve port 7, valve port is blocked, then now valve port 7 is completely closed.
