Description
Technical field
This utility model relates to field of petroleum machinery, is specifically related to a kind of high pressure VR and blocks up.
Background technology
At present, when external wellhead maintenance or replacing tubing head both sides valve, for preventing blowout and well kick, VR must be loaded onto by specific purpose tool at tubing head side outlet to block up, well fluid-tight is got lodged in well head, in order to keep in repair or change valve, after maintenance or more having changed jobs, take out VR by specific purpose tool again to block up, recover normal operating conditions.Particularly high pressure flowing well, with greater need for a kind of dependable performance, VR simple to operate blocks up, the well head that current Domestic Oil And Gas Fields uses, almost without this function, beyond once occurring, or tubing head lateral wing valve leak, it is impossible to change valve, kill-job operation can only be taked, the method not only destroys bottom pressure, is sometimes also possible to make well head scrap, adds operating cost.Especially high-pressure gas well, without subfunction, once leaks, it will occur that the serious accident that people dies ruined by well.
Summary of the invention
The purpose of this utility model is: provides a kind of easy to operate, bears the high high pressure VR of pressure and block up.
This utility model is achieved through the following technical solutions: a kind of high pressure VR blocks up, including:
Body: be sequentially formed with outer-hexagonal, external screw thread and annular groove from head end to tail end outside it, is sequentially formed with female thread chamber, spool chamber and spring cavity from head end to tail end inside it, and described female thread cavity wall is provided with female thread；
Spool: be placed in described spool chamber, its afterbody is formed with inclined-plane boss, and described spool chamber is provided with the inclined-plane corresponding with inclined-plane boss；
Spring: being placed in described spring cavity, its head end is connected to the tail end of described spool, and its tail end is fixed in described spring cavity；
Sealing ring: be placed in described annular groove.
As further preferred version, also include that seal spool pad, described seal spool pad are located on the inclined-plane of described inclined-plane boss.
As further preferred version, also including jump ring, described jump ring fixes the tail end of spring in being arranged on described spring cavity.
Compared with prior art, this utility model has the advantages that
VR of the present utility model blocks up, and simple in construction is easy to operate, and snubbing serving is fully achieved, it is achieved safe and environment-friendly, efficiently produce.
Accompanying drawing explanation
Fig. 1 is the structural representation of body of the present utility model；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figures 1 and 2, a kind of high pressure VR blocks up, including: body 1, spool 2, spring 3, sealing ring 4, seal spool pad 22 and jump ring 5.
The outside of body 1 is sequentially formed with outer-hexagonal 11, external screw thread 12 and annular groove 13 from head end to tail end, operate when outer-hexagonal 11 is used for installing, realizing being connected with tubing head by external screw thread 12, sealing ring 4 is located in annular groove 13, is formed and seal when being used for connecting between body 1 and oil pipe.
The inside of body 1 is sequentially formed with female thread chamber 14 from head end to tail end, spool chamber 15 and spring cavity 16, described female thread chamber 14 inwall is provided with female thread, the convenient VR of taking-up blocks up, spool 2 is located in spool chamber 15, the afterbody of spool 2 is formed with inclined-plane boss 21, described spool chamber 15 is provided with the inclined-plane 151 corresponding with inclined-plane boss 21, and seal spool pad 22 is set on the inclined-plane of inclined-plane boss 21, make to be formed between spool 2 and spool chamber 15 to seal, spring 5 is located in spring cavity 16, one end is connected to the afterbody of spool 2, the other end is fixed in spring cavity 16 by jump ring 5.
