Abstract
The utility model provides an antitheft valve structure which is reasonable in structural design, is easy to disassemble and assemble, and is good in antitheft effect. The structure comprises a valve body, and a valve cover in a flange structure. The valve cover is fixedly installed with the valve body through a connecting flange. A protective cover is disposed above the valve cover. The inner wall of the protective cover is attached to an installation bolt of the connecting flange, and two sides of the protective cover cover a side part of the connecting flange. A threaded connection part of the valve body is in cooperation connection with a special-shaped nut which is provided with a raised heat part. The special-shaped nut is sleeved by a cover body which is provided with a central hole. The special-shaped nut passes through the central hole and extends out of the cover body, and is provided with a clamping ring in a sleeved manner. The bottom of the cover body covers the upper surface of the protective cover in a pressing manner. The structure also comprises a sleeve wrench which is matched with the shape of the special-shaped nut.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of valve for guarding against theft structure.
Background technique
At present, the delivery lines such as combustion gas, heating power, oil dispose a large amount of valves, pipeline valve is along the line because the shortage of supervision often occurs by pirate of the open and steals the phenomenon of closing, especially be arranged on valve on oil extraction in oil field device because working environment many places are in field, easily lose without parts such as the valves of anti-theft feature, may cause equipment operation exception to cause work safety accident, also can cause any property loss because of stolen.
Conventional valve for guarding against theft structure adopts the nonstandard bolt of simple designs substantially, coordinate special spanner dismounting, although valve for guarding against theft structure has prevented the generation of pirate of the open valve phenomenon to a certain extent in this, but valve attachment portion does not add protective housing, the connecting bolt extracting tool comparison of nonstandard form is easy, meanwhile, the adpting flange of valve body and valve gap junction point only adopts conventional bolt arrangement, the danger that also exists valve to be opened by adpting flange place.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of reasonable in design, easy disassembling, and the valve for guarding against theft structure of good anti-theft effect.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of valve for guarding against theft structure, comprise the valve gap of valve body and flange arrangement, described valve gap is installed fixing by adpting flange and valve body, valve gap top is also provided with protecting cover, construction bolt laminating and the both sides of protecting cover inwall and adpting flange cover adpting flange sidepiece, the threaded joints of valve body and an abnormity nut are connected, abnormity nut is provided with protruding head, abnormity nut is arranged with cover body outward, cover body is provided with center hole, abnormity nut stretches out outside cover body through center hole and is set with snap ring, cover body bottom is overlaid on protecting cover upper surface, described valve for guarding against theft structure also comprises a socket wrench matching with abnormity nut nose shape.
As the further restriction of the technical program, described protecting cover is fixed by embedded screw and valve gap.
The beneficial effects of the utility model are according to known to the narration of such scheme:
Adopt the valve for guarding against theft of said structure, by the design of cover body, abnormity nut and the socket wrench that coordinates with abnormity nut, make valve be difficult to utilize conventional instrument to disassemble, effectively prevent potential safety hazard and property loss that valve pirate of the open causes; And this valve for guarding against theft structure is also designed with the protecting cover of capping valve gap and valve body junction point, make the clamping bolt of junction point adpting flange can, because of being exposed to danger outer and that easily dismantled, not strengthen the anti-theft effect of valve.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's valve mechanism schematic diagram;
Fig. 2 is the utility model embodiment's Wrench head structural representation;
In figure, be labeled as:
1, valve body; 2, valve gap; 3, protecting cover; 4, abnormity nut; 5, cover body; 6, snap ring; 7, screw; 8, construction bolt; 9, socket wrench working part; 10, special impression.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
As shown in drawings, the valve for guarding against theft structure that the present embodiment provides, comprise the valve gap 2 of valve body 1 and flange arrangement, described valve gap 2 is installed fixing by adpting flange and valve body 1, valve gap 2 tops are also provided with protecting cover 3, the construction bolt 8 of protecting cover 3 inwalls and adpting flange is fitted and both sides cover adpting flange sidepiece, the threaded joints of valve body 1 and an abnormity nut 4 are connected, abnormity nut 4 is provided with protruding head, the outer cover body 5 that is arranged with of abnormity nut 4, cover body 5 is provided with center hole, abnormity nut 4 stretches out outside cover body 5 through center hole and is set with snap ring 6, cover body 5 bottoms are overlaid on protecting cover 3 upper surfaces, described valve for guarding against theft structure also comprises a socket wrench matching with abnormity nut 4 nose shapes, socket wrench working part 9 is provided with special impression 10.
In the present embodiment, described protecting cover 3 is fixing with valve gap 2 by embedded screw 7.
The valve for guarding against theft of said structure, by the design of cover body 5, abnormity nut 4 and the socket wrench that coordinates with abnormity nut 4, makes valve be difficult to utilize conventional instrument to disassemble, and effectively prevents potential safety hazard and property loss that valve pirate of the open causes; And this valve for guarding against theft structure is also designed with the protecting cover 3 of capping valve gap 2 and valve body 1 junction point, make the clamping bolt of junction point adpting flange can, because of not being exposed to danger outer and that easily dismantled, not strengthen the anti-theft effect of valve.
In the above-described embodiments, preferred embodiments of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations.At this, should illustrate, any change of making under inventive concept of the present utility model all will fall in protection domain of the present utility model.
