The utility model has the advantages of simple structure, the valve body inner chamber matees with the structure of outer cylinder bushing, interior cylinder liner, piston head, thrust head, push rod and spring, and the installation of being convenient for has improved assembly efficiency, and is with low costs, easily realizes, is suitable for popularization and application.

Description

Downhole safety valve body
Technical field
The utility model relates to storm valve technical field, refers to a kind of downhole safety valve body especially.
Background technique
Due to the generally application of CNG technology, constantly increase using compressed natural gas (CNG) as the high pressure gas filling station of supply, CNG well for storage also enters the visual field of people.And in the manufacturing operation process of reality, underground high-voltage gas storage well is often found following several problem: parts Problems existing such as the potential safety hazard that burn into side leakage, shaft bottom end socket exist and technological deficiency, drainage device exists in the well of shaft bottom potential safety hazard and control heads.And the high-pressure gas storage well major part in CNG gas station is built in the intensive city of Crowds Distribute, rock gas, once reveal and be gathered in surrounding environment, will become the major hidden danger of serious accident, and may lead to irremediable having a strong impact on.Therefore need a kind of storm valve of well for storage of high pressure gas, valve body is one of requisite structure of safety valve.
Model utility content
The utility model proposes a kind of downhole safety valve body of novel structure.
The technical solution of the utility model is achieved in that a kind of downhole safety valve body, comprise valve body body, described valve body is a hollow cylinder, one end of described valve body is one-body molded annular protrusion, the depressed part of a hollow is also provided with in described valve body, one end of described depressed part is connected with projection, and the other end connects " convex " shape circular cylindrical cavity logical in, and the bottom of described " convex " shape circular cylindrical cavity makes the inner chamber bottom it form a circular groove to in-flanges.
Wherein, described projection extends to body cavity, and described protruding inner side has groove.
Particularly, described depressed part is a ring bodies, and the cross section of described depressed part is arcuation.
Further, the described outer wall of " convex " shape circular cylindrical cavity and the spacing of valve interior wall are 2 ~ 8 centimetres.
Further, the sidewall of described valve body has through hole.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, the structure matching of body cavity and outer cylinder sheath, inner cylinder liner, piston head, thrust head, push rod and spring, be convenient to install, improve efficiency of assembling, cost is low, be easy to realize, be suitable for applying.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is that the utility model partly cuts open structural representation;
Fig. 2 is the plane structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1 and Fig. 2, a kind of downhole safety valve body, comprise valve body body, described valve body is a hollow cylinder 1, one end of described valve body is one-body molded annular protrusion 2, is also provided with the depressed part 3 of a hollow in described valve body, and one end of described depressed part 3 is connected with protruding 2, the other end connects " convex " shape circular cylindrical cavity 4 logical in, and the bottom of described " convex " shape circular cylindrical cavity 4 makes the inner chamber bottom it form a circular groove 6 to in-flanges 7.Structure of the present utility model is simple, the structure matching of body cavity and outer cylinder sheath, inner cylinder liner, piston head, thrust head, push rod and spring, is convenient to install, and improve efficiency of assembling, cost is low, is easy to realize, is suitable for applying.
Wherein, described protruding 2 extend to body cavity, and depressed part 3 is connected to the bottom of protruding 2 extension parts, makes to there is a determining deviation between depressed part 3 and valve interior wall, prevents mutual wearing and tearing, make safety valve radiating effect better simultaneously.And having groove 8 inside described protruding 2, the setting of groove 8 is convenient to be connected with the fin on outer cylinder sheath, plays the effect of cooperation.
Particularly, described depressed part 3 is a ring bodies, and the cross section of described depressed part 3 is arcuation, and the top of outer cylinder sheath is placed in depressed part 3, makes body cavity space compacter, installs more convenient.
The described outer wall of " convex " shape circular cylindrical cavity 4 and the spacing of valve interior wall are 5 centimetres, and good heat dissipation effect in the process of work, valve inner part is coordinated more, attractive in appearance.
The sidewall of described valve body has through hole 5, for being exhausted to valve inner.
The utility model when mounted, first outer cylinder sheath is installed in valve body sunken inside portion 3, inner cylinder liner and piston head are installed again, thrust head is installed in the lower end of piston head, in ball bottom thrust head, push rod is installed, bottom push rod runs through down " convex " shape circular cylindrical cavity 4, mounting spring in described circular groove 6, on the flange 7 caved inward bottom spring housing is connected on down " convex " shape circular cylindrical cavity 4.Assembling is simple, and novel structure is with low cost.Described depressed part 3, " convex " shape circular cylindrical cavity 4 that falls are all coaxial with valve body, stable after assembling.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
