Abstract
The utility model discloses a sealing strip for sealing a wellhole pipe and a well base on a plastic inspection well, and aims at providing a sealing strip which is reasonable in design and good in sealing performance and is used for sealing the wellhole pipe and the well base on the plastic inspection well. The sealing strip is composed of an annular sealing strip body. The sealing strip body extends upwards along the center axis of the annular sealing strip body to form a cylinder. The outer surface of the sealing strip body is at least provided with two saw-toothed protruding ribs heightened gradually, and the distance between the protruding ribs is at least 0.5 cm. One end of the sealing strip body is provided with a check ring which is connected with the sealing strip body into a whole. The sealing strip has the advantages of being simple in structure, reasonable in design, convenient to use and the like.
Description
Technical field
The utility model has related to a kind of weather strip for sealed well bobbin and well seat.
Background technology
Wellbore tubular and well seat are generally plastic material formation at present, wellbore tubular with well seat when being connected, the weather strip using generally is common on the market annular sealing strip, sealing bar is used designedly owing to not aiming at when wellbore tubular is connected with well seat, make to exist that design is unreasonable, sealing is poor and the shortcoming such as leakage.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the weather strip for sealed well bobbin and well seat is provided on a kind of plastic inspection well of reasonable in design, good airproof performance.
In order to achieve the above object, on the designed a kind of plastic inspection well of the utility model, for the weather strip of sealed well bobbin and well seat, it consists of annular weatherstrip body, and extends upward to cylinder along the central axis of this annular sealing strip body; External surface in weatherstrip body is at least provided with two jagged raised ribs of increasing gradually, and the spacing between raised ribs and raised ribs is at least 0.5cm, in one end of weatherstrip body, is also provided with back-up ring, and back-up ring and weatherstrip body link into an integrated entity.
As preferably, the height that raised ribs is increased is gradually 0.5～1mm.
As preferably, the spacing between raised ribs and raised ribs is 0.5～1cm.
As preferably, the width of back-up ring is 0.5～1.5cm.
According on above-described a kind of plastic inspection well for the weather strip of sealed well bobbin and well seat, in use, the one end that is provided with back-up ring is close on the cushion cap of well seat, and the jagged raised ribs of increasing is gradually close to the tube connector inwall of well seat on the weather strip external surface of annular, the sealing function when then playing wellbore tubular and be connected with well seat by sealing bar.Therefore, it has the features such as simple in structure, reasonable in design and easy to use.
