Abstract
The utility model provides a pipeline leaking point shutoff instrument, relates to pipeline rehabilitation instrument technical field, and including support, thread bush and bolt, the thread bush welds in the round hole of support upper surface, and the bolt passes through screw thread and threaded sleeves connected, and the support is down the U -shaped, and the afterbody processing of bolt has the circular cone. The utility model discloses the operation can also be pressed in area under the occurrence attitude incessantly to effective shutoff leak source not only, does not influence the normal clear of production, has reduced cost of maintenance, the thread bush adopts stainless steel material to make, makes the utility model discloses can not guarantee the internal screw thread integrity because of using for a long time or placing and the corrosion, messenger's instrument can repetitious usage, with the tapering setting between 14 to 12, the minimum set up the keenness of having guaranteed the circular cone, make the operation more laborsaving, the maximum value set up the intensity of having guaranteed the circular cone, make its pointed end can not break.
Description
Technical field:
The utility model relates to pipeline rehabilitation technical field of tools, refers in particular to a kind of Pipeline Leakage Point capping tools.
Background technique:
Pipeline uses to certain time limit, can because the reasons such as corrosion produce leakage point.Often adopt the method for directly welding to carry out leak stopping operation in conventional art, when adopting in this way, must manifold pressure be eliminated, namely must stop production.Loss can be brought to production.In addition, this method be difficult to ensure shutoff quality.
Summary of the invention:
The purpose of this utility model is to provide a kind of Pipeline Leakage Point capping tools, also fully ensures leak stopping quality with the pressure sealing realized in not stopping production situation.
The purpose of this utility model realizes as follows: a kind of Pipeline Leakage Point capping tools, comprise support, thread bush and bolt, support is inverted U-shaped, and thread bush is welded in the circular hole of rack upper surface, bolt is connected with thread bush by screw thread, and the afterbody of bolt is processed with circular cone.The range of taper of described circular cone is 1/4 to 1/2.
Bolt in such scheme is outer-hexagonal bolt.Described thread bush is made up of stainless steel material.
The beneficial effects of the utility model are: 1, the utility model not only can effective shutoff leak source, can also be with press operation, do not affect normally carrying out of production, reduce maintenance cost under not end-of-life state; 2, thread bush adopts stainless steel material to make, and makes the utility model can not the corrosion because of Long-Time Service or placement, ensure that the integrity of internal thread, instrument can repeatedly be used; 3, be arranged between 1/4 to 1/2 by tapering, the setting of minimum value ensure that the acuteness of circular cone, makes operation more laborsaving; The setting of maximum value ensure that the intensity of circular cone, and its tip can not be fractureed.
Accompanying drawing illustrates:
Fig. 1 is plan view of the present utility model;
Fig. 2 is the left view of Fig. 1.
In figure: 1-circular cone; 2-support; 3-thread bush; 4-bolt.
Embodiment:
With reference to accompanying drawing, the utility model comprises support 2, thread bush 3 and bolt 4, and support 2 is in inverted U-shaped, and thread bush 3 is welded in the circular hole of support 2 upper surface, and bolt 4 is connected with thread bush 3 by screw thread, and the afterbody of bolt 4 is processed with circular cone 1.Described bolt 4 is outer-hexagonal bolt.Described thread bush 3 is made up of stainless steel material.The range of taper of described circular cone 1 is 1/2 to 1/4.
Using method of the present utility model is:
During use, after leak source is aimed at the tip of circular cone 1 on bolt 4, the both wings of support 2 are welded on pipeline, then make it press to leak source with spanner swivel bolt 4, under very large pressure effect, the conical surface of circular cone 1 can be fitted completely with leak source edge, realizes preliminary shutoff; After preliminary shutoff, the gap that circular cone 1 contacts with leak source is welded, realizes final shutoff.After shutoff, bolt 4 and support 2 are cut, when next time uses, only need change bolt 4.
The utility model not only can effective shutoff leak source, can also be with press operation, do not affect normally carrying out of production, reduce maintenance cost under not end-of-life state.Thread bush 3 adopts stainless steel material to make, and makes the utility model can not the corrosion because of Long-Time Service or placement, ensure that the integrity of internal thread, instrument can repeatedly be used; Be arranged on by tapering between 1/4 to 1/2, the setting of minimum value ensure that the acuteness of circular cone 1, makes operation more laborsaving; The setting of maximum value ensure that the intensity of circular cone 1, and its tip can not be fractureed.
