Abstract
Provided is a drilling-accompanying measuring instrument housing circuit sealing cover, comprising a sealing cover body (4), wherein the bottom of the sealing cover body (4) is provided with a radial O-shaped sealing ring (2) in the circumferential direction; the lower portion of the sealing cover body (4) is provided with an axial O-shaped sealing ring (3) in the circumferential direction; the edge of the sealing cover body (4) is provided with a loop of chamfers (1) at the angle of 1.5 times 45 degrees; and an O-shaped sealing ring is arranged at the chamber. The drilling-accompanying measuring instrument housing circuit seal cover integrates the axial sealing and the radial sealing, with the radial-axial sealing being added, thereby substantially improving the sealing capability of the instrument, enhancing the stability of the instrument, and prolonging the service lifetime of the instrument.
Description
Technical field
[0001] the utility model relates in the oil drilling field a kind of with boring sealing device, particularly a kind of measurement while-drilling instrument housing circuit sealing lid.
Background technology
The utility model relates in the oil drilling field a kind of with boring sealing device, particularly a kind of measurement while-drilling instrument housing circuit sealing lid.
Summary of the invention
In order to solve the problem that exists in the background technology; The utility model provides a kind of measurement while-drilling instrument housing circuit sealing lid; This measurement while-drilling instrument housing circuit sealing lid has merged axial seal and radial seal, and has added the footpath shaft seal, has increased the sealability of instrument greatly; Improve the stability of instrument, prolonged the useful life of instrument.
The technical scheme of the utility model is: this measurement while-drilling instrument housing circuit sealing lid comprises cap body; The cap body bottom surface is along upwards being provided with radially " O " shape sealing ring week; The cap body bottom is along upwards being provided with axially " O " shape sealing ring week; The cap body edge is processed with the chamfering of 1.5 * 45 ° on a circle, and the chamfering place is provided with " O " sealing ring.
The utlity model has following beneficial effect: the utility model overcome the simple axial seal of circuit board seal cover or the shortcoming of radial seal; Axial seal and radial seal have been merged; And added the footpath shaft seal, prevent to lose efficacy owing to the single sealing ring that vibration, high temperature, high pressure cause.Increase the sealability of instrument greatly, improved the stability of instrument, prolonged the useful life of instrument.
Description of drawings:
Accompanying drawing 1 is the structure cutaway view of the utility model.
Among the figure 1, chamfering; 2, radially " O " shape sealing ring; 3, axial " O " shape sealing ring; 4, cap body.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; This measurement while-drilling instrument housing circuit sealing lid comprises cap body 4; Described cap body 4 bottom surfaces are along upwards being provided with radially " O " shape sealing ring 2 week, and radially " O " shape sealing ring 2 guarantees radial seal, and cap body 4 bottoms are along upwards being provided with axially " O " shape sealing ring 3 week; Axially " O " shape sealing ring 3 guarantees axial seal; Cap body 4 edges are processed with the chamfering 1 of 1.5 * 45 ° on a circle, and the chamfering place is provided with " O " sealing ring and guarantees radial and axial sealing simultaneously, guarantees the sealing at Instrument shell circuit board and line place.
During use, after radially " O " shape sealing ring 2 places with axial " O " shape sealing ring 3, coat silicone grease lubricating grease; After chamfering 1 prescription shape sealing ring is coated silicone grease lubricating grease, put into the edge of respective housings seal groove.Housing seal groove place puts into seal cover, tightens four screws and gets final product.
