Description
Technical field
The utility model relates to a kind of hydraulic tongs pipeline leakproof special joint.
Background technique
In current underground work, in oil discharge pipe's operation, hydraulic tongs pipe joint leakage of oil situation is more outstanding, current hanging joint mainly seals by seal ring, shortcoming is easy leakage, life-span casual labourer needs frequently to change seal ring in doing, effect is also bad, cause the very large wasting of resources, also result in the pollution on ground simultaneously.The loss of oil plant can cause the increase of construction cost in addition.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic tongs pipeline leakproof special joint, thoroughly can eliminate pipe joint and leak oil condition, reduce construction cost, prevent ground pollution.
The purpose of this utility model realizes like this, a kind of hydraulic tongs pipeline leakproof special joint, comprise pin and box sub, in pin and box sub, Self-sealing valve is set respectively, the matching surface that both pin and box subs contact is respectively the coned face of male-female engagement, the coned face of male-female engagement forms sealing surface, the periphery wall of tool joint pin arranges outside thread, one annular shoulder block is set in the middle part of the periphery wall of female joint, the outer sliding fiting sleeve of female joint is filled with a connecting filament clasp, the internal thread that the inwall of connecting filament clasp is arranged is connected with the outside thread that tool joint pin outer wall is arranged, the lower end of connecting filament clasp is positioned at below described annular shoulder block.
When the utility model uses, realize seal action by the male-female engagement conical surface of pin and box sub, sealing effect spy is good, leak tight connecting filament clasp once just passable, thoroughly can eliminate pipe joint and leak oil condition, reduce construction cost, prevent ground pollution, long service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view;
Fig. 2 is that the master of the another kind of embodiment of the utility model looks cross-sectional view.
Embodiment
A kind of hydraulic tongs pipeline leakproof special joint, as shown in Figure 1, comprise tool joint pin 4 and female joint, Self-sealing valve 1 is set in pin and box sub respectively, the matching surface that both pin and box subs contact is respectively the coned face 2 of male-female engagement, 3, the coned face 2 of male-female engagement, 3 form sealing surface, the periphery wall of tool joint pin 4 arranges outside thread, one annular shoulder block 6 is set in the middle part of the periphery wall of female joint, the outer sliding fiting sleeve of female joint is filled with a connecting filament clasp 5, the internal thread that the inwall of connecting filament clasp 5 is arranged is connected with the outside thread that tool joint pin 4 outer wall is arranged, the lower end of connecting filament clasp 5 is positioned at below described annular shoulder block 6.Improve as one of the present utility model, the coned face 2,3 of described male-female engagement can swap round position, the coned face 2 of indent can be arranged in female joint, and the coned face 3 of evagination can be arranged in tool joint pin 4, and use and sealing effect are the same.This kind of distressed structure also should fall within protection domain of the present utility model.Same, as shown in Figure 2, the position of connecting filament clasp 5 also can be arranged in tool joint pin 4, and this kind of distressed structure also should fall within protection domain of the present utility model.
