Abstract
The utility model discloses a kind of constrained position leak stoppage device, comprise bolt, nut, compressing tablet, rubber and flat key, described bolt passes the middle part of compressing tablet and rubber, a groove is opened in an end of bolt, described flat key is provided with through hole, flat key to be plugged in groove and to be connected by through hole pin, and flat key freely can rotate along pin in groove, and the other end of bolt is threaded nut.The utility model compared with prior art, have the following advantages: reasonable in design, structure simply, easily makes, originally common clipping repair outfit and the indeterminable Lost circulation problems of cluster repair outfit, after the acting point of the utility model leak stoppage device changes, be obtained for solution, solve the problem of the process difficulty of large tank and the perforation of specific position place.
Description
Technical field
The utility model relates to oil field oil storage tank leakage stopping technology field, is specifically related to a kind of constrained position leak stoppage device.
Background technology
Oil field individual well draws the tank body of oil tank, the reasons such as corrosion in use easily cause the perforated phenomenon of local, oil tank is drawn to belong to inflammable and explosive container, the measure such as electricity, gas welding can not be taked to repair, and what the restriction due to the shape and size of tank body was conventional check card, and son waits leaking-stopping measure also cannot block leak point.Change and draw oil tank to be a complicated engineering, be difficult in the short time, so the normal production of drawing oil well can not be ensured before changing tank.Because the restriction of position causes conventional sub-blocking method of checking card cannot carry out shutoff when the concealment part such as elbow, threeway, four-way of external transport pipeline is bored a hole, well can only be stopped and change, easily cause a large amount of production losses.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, provides a kind of constrained position leak stoppage device.
Its technical scheme is: constrained position leak stoppage device, comprise bolt, nut, compressing tablet, rubber and flat key, described bolt passes the middle part of compressing tablet and rubber, a groove is opened in an end of bolt, described flat key is provided with through hole, flat key to be plugged in groove and to be connected by through hole pin, and flat key freely can rotate along pin in groove, and the other end of bolt is threaded nut.
Wherein, the width of described flat key and the equal diameters of bolt.Spring chair is provided with between described nut and compressing tablet.Described through hole is not identical to the distance at flat key two ends.Described compressing tablet is arcuate structure.
The utility model compared with prior art, have the following advantages: reasonable in design, structure simply, easily makes, originally common clipping repair outfit and the indeterminable Lost circulation problems of cluster repair outfit, after the acting point of the utility model leak stoppage device changes, be obtained for solution, solve the problem of the process difficulty of large tank and the perforation of specific position place.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of constrained position leak stoppage device, comprise bolt 1, nut 2, compressing tablet 3, rubber 4 and flat key 5, described bolt 1 passes the middle part of compressing tablet 3 and rubber 4, and open a groove 6 in an end of bolt 1, described flat key 5 is provided with through hole, flat key 5 to be plugged in groove 6 and to be connected by through hole pin 7, the diameter of through hole is greater than the diameter of pin 7, and therefore flat key 5 freely can rotate along pin 7 in groove 6, and the other end of bolt 1 is threaded nut 2.The width of described flat key 5 and the equal diameters of bolt 1.Spring chair 8 is provided with between described nut 2 and compressing tablet 3.Described through hole is not identical to the distance at flat key 5 two ends.Described compressing tablet 3 is arcuate structure.
When there is perforation in the tank body of oil tank, according to the leak stoppage device that the size Selection of site of perforation is suitable, first by flat key 5 key body and bolt 1 afterbody wedging perforation place, heavy body is not waited because lead to the hole site on flat key 5 key body defines the two ends centered by pin 7 by flat key, when bolt 1 afterbody enters site of perforation, flat key 5 deflects, on when carrying bolt 1 flat key 5 be just stuck in perforation place, a failure-free acting point is defined in perforation inner side, due to the uniform pressure of compressing tablet 3 after tightening nuts 2, by rubber 4 tightly be squeezed in leak point place, the characteristic expanded after rubber 4 pressurized makes it firmly be blocked by leak point.Originally common clipping repair outfit and the indeterminable Lost circulation problems of cluster repair outfit, be obtained for solution after the acting point of this leak stoppage device changes, and solves the problem of the process difficulty of large tank and the perforation of specific position place.
