Abstract
The stifled oily component of one kind, stifled plug cock and seal receptacle comprising mechanical connection, seal receptacle is arranged on stifled plug cock bottom, and stifled plug cock and seal receptacle are all disposed within the oil filler point of cylinder body, and stifled plug cock is threadedly coupled with oil filler point, and seal receptacle contacts sealing with oil filler point.In the stifled oily component that the utility model is provided, stifled plug cock screw thread is not involved in sealing function, only serves and screws, can reduce the difficulty of screw thread process, seal with elastometic washer is substituted using metal hard-sealing between seal receptacle and cylinder body oil filler point simultaneously, sealing ring is significantly reduced and damages the failure risk brought.
Description
Technical field
The utility model is related to a kind of for petroleum drilling and mining jarring tool and the stifled oily component of shock absorbing tool.
Background technology
Petroleum drilling and mining in the cylinder body of jarring tool and shock absorbing tool with hydraulic oil is equipped with, to meet oiling requirement, in cylinder
Oil filler point is all provided with body, needs to use stifled plug cock to block oily plug-hole after the completion of oiling, to ensure cylinder interior
Hydraulic oil can not be leaked to outside cylinder body.
Each jarring both at home and abroad and shock absorbing tool manufactory mainly realize the closure of hydraulic oil using following two schemes at present：
The first scheme：As shown in figure 1, oil is stifled plus rubber ring realizes function, stifled oil is set at the oil filler point of cylinder body 1 '
Plug 2 ', blocks up on plug cock 2 ' and sets rubber ring 3 ' to realize sealing；
Second scheme：As shown in Fig. 2 thread seal realizes function, in cylinder body 1 ' ' oil filler point at stifled plug cock is set
2 ' ', block up plug cock 2 ' ' with oil filler point by seal screw thread realize sealing.
Rubber ring in the first scheme is easily damaged when installing or using causes disabler, in second scheme
Processing sealing screw thread is needed on stifled plug cock, and seals screw thread not easy processing, once processing, which goes wrong, easily causes disabler.
The content of the invention
The utility model provides a kind of stifled oily component, reduces the difficulty of screw thread process, while reducing sealing ring damage
The failure risk brought.
In order to achieve the above object, the utility model provides a kind of stifled oily component, comprising：The stifled plug cock and close mechanically connected
Seat is sealed, seal receptacle is arranged on stifled plug cock bottom, stifled plug cock and seal receptacle are all disposed within the oil filler point of cylinder body, block up plug cock and oiling
Hole is threadedly coupled, and seal receptacle contacts sealing with oil filler point.
Described seal receptacle and stifled plug cock riveting.
Described stifled plug cock and seal receptacle all use metal material.
Described stifled plug cock has external screw thread, and described oil filler point has internal thread, and stifled plug cock passes through external screw thread and oiling
The internal thread of hole inwall realizes threaded connection.
Described seal receptacle has a male cone (strobilus masculinus), has inner conical surface at the ledge structure of described oil filler point, seal receptacle passes through
Male cone (strobilus masculinus) is realized with the inner conical surface of oil filler point contacts sealing.
The gradient of described male cone (strobilus masculinus) and the gradient of the inner conical surface of oil filler point ledge structure match, and realize seal receptacle
The complete gluing, sealing of the inner conical surface of male cone (strobilus masculinus) and oil filler point.
In the stifled oily component that the utility model is provided, stifled plug cock screw thread is not involved in sealing function, only serves and screws, can be with
The difficulty of screw thread process is reduced, while substituting seal with elastometic washer using metal hard-sealing between seal receptacle and cylinder body oil filler point, is shown
Write and reduce the failure risk that sealing ring damage is brought.
Brief description of the drawings
Fig. 1 is the schematic diagram of the first hydraulic oil closure mode in background technology.
Fig. 2 is the schematic diagram of second of hydraulic oil closure mode in background technology.
Fig. 3 is a kind of structural representation for stifled oily component that the utility model is provided.
Embodiment
Preferred embodiment of the present utility model is illustrated below according to Fig. 3.
As shown in figure 3, the utility model provides a kind of stifled oily component, comprising：The stifled plug cock 2 and seal receptacle 3 mechanically connected,
Seal receptacle 3 is arranged in the stifled bottom of plug cock 2, the present embodiment, seal receptacle 3 and the riveting of stifled plug cock 2, blocks up plug cock 2 and seal receptacle 3
It is all disposed within the oil filler point 11 of cylinder body 1, blocks up plug cock 2 and seal receptacle 3 and all use metal material, blocking up plug cock 2 has external screw thread, blocks up
Plug cock 2 realizes and is threadedly coupled that seal receptacle 3 has male cone (strobilus masculinus) 301, the outer cone by external screw thread with the internal thread of the inwall of oil filler point 11
The gradient in face 301 and the gradient of the inner conical surface 101 of the ledge structure of oil filler point 11 match, it is possible to achieve outside seal receptacle 3
The complete gluing, sealing of inner conical surface 101 of the conical surface 301 and oil filler point 11.
As shown in figure 3, when installing, the screw-internal thread fit of the external screw thread of plug cock 2 and the oil filler point 11 of cylinder body 1 is blocked up, by stifled oil
Plug 2 is screwed to the direction of arrow, and stifled plug cock 2 drives seal receptacle 3 to be compressed to the direction of arrow, makes the male cone (strobilus masculinus) of seal receptacle 3 and oil filler point 11
Inner conical surface compress, realize sealing function.
In the stifled oily component that the utility model is provided, stifled plug cock screw thread is not involved in sealing function, only serves and screws, can be with
The difficulty of screw thread process is reduced, while substituting seal with elastometic washer using metal hard-sealing between seal receptacle and cylinder body oil filler point, is shown
Write and reduce the failure risk that sealing ring damage is brought.
Although content of the present utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as to limitation of the present utility model.After those skilled in the art have read the above, for
A variety of modifications and substitutions of the present utility model all will be apparent.Therefore, protection domain of the present utility model should be by appended
Claim limit.
