Abstract

The invention relates to a sealing ring for underwater experiment of a stainless steel pipe, which comprises a main body, wherein an internal diameter of the main body is gradually reduced from a flat end on one side to a pointed end on the other side. The sealing ring provided by the invention has the advantages that the use effect and service life of the sealing ring are largely enhanced because the gradually reduced diameter is adopted, the replacing frequency is reduced, and thus the production efficiency is increased.

Description

Stainless-steel tube is tested the O-ring seal of usefulness under water
Technical field
The present invention relates to a kind of O-ring seal, relate in particular to the O-ring seal that a kind of stainless-steel tube is tested usefulness under water.
Background technology
Air underwater pressure test is the bubble-tight important tests of stainless-steel tube, and is extremely important to the impermeability of checking steel pipe.
O-ring seal circle road radius one end that stainless-steel tube air underwater pressure test of the prior art is used to tip is the same, and steel pipe inserts O-ring seal, and O-ring seal wraps steel pipe and reaches sealing effectiveness.Often test in the practical operation 3,4 times, O-ring seal can only not changed with regard to reaching seal request.
Summary of the invention
The technical issues that need to address of the present invention have provided the O-ring seal that a kind of stainless-steel tube is tested usefulness under water, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: body; The internal diameter of described body by a side flush end to the most advanced and sophisticated progressive diameter reduction of opposite side.
Compared with prior art, the invention has the beneficial effects as follows: owing to adopt progressive diameter reduction, the result of use and the life-span of O-ring seal strengthen greatly, have reduced the replacing number of times, thereby have improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that steel pipe inserts synoptic diagram of the present invention.
Fig. 3 adopts the present invention to test the structural representation of stainless-steel tube.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: body 1; The internal diameter of described body 1 by a side flush end to the most advanced and sophisticated progressive diameter reduction of opposite side.
The mode that the present invention adopts a flat end to reduce gradually to most advanced and sophisticated circle road radius, (Fig. 2 when steel pipe inserts O-ring seal 1 punching press, among the figure: stainless-steel tube 5), because most advanced and sophisticated radius is less, when the effect hour circle road that is under pressure dwindles, can more seeing of steel pipe parcel is tight, guaranteed the sealing of O-ring seal, make that the efficient of the hydraulic testing is higher.
As seen from Figure 3: stainless-steel tube that C refers to 5 and O-ring seal 1 surface of contact, simultaneously under the thrust of first fastener, 3 upper push-rods 2 (among the figure: stationary installation 4), A of the present invention, B place (ring-like) is squeezed and reaches the double seal effect.Because adopt progressive diameter reduction, the result of use and the life-span of O-ring seal strengthen greatly, have reduced the replacing number of times, thereby have improved production efficiency.

Claims (1)

1. a stainless-steel tube is tested the O-ring seal of usefulness under water, comprising: body; It is characterized in that: the internal diameter of described body by a side flush end to the most advanced and sophisticated progressive diameter reduction of opposite side.
