Abstract
The utility model relates to a sealing ring for a stainless-steel pipe underwater experiment, which comprises a body; the inside diameter of the body gradually reduces from the flat end at one side to the tip end at the other side; and the sealing ring for the stainless-steel pipe underwater experiment has the beneficial effects that: because the gradually-reduced diameter is adopted, the using effect and the service life of the sealing ring are greatly enhanced, the replacing times are reduced, and therefore the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to the seal ring that a kind of Stainless Steel Tube is tested usefulness under water.
Background technique
Air underwater pressure test is the bubble-tight important tests of Stainless Steel Tube, and is extremely important to the tightness of checking steel pipe.
Seal ring 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 seal ring, and seal ring wraps steel pipe and reaches sealing effect.Often test in the practical operation 3,4 times, seal ring can only not changed with regard to reaching seal request.
Summary of the invention
The utility model technical issues that need to address have provided the seal ring 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 utility model is achieved through the following technical solutions:
The utility model comprises: 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 beneficial effects of the utility model are: owing to adopt progressive diameter reduction, the using effect and the life-span of seal ring strengthen greatly, have reduced the replacing number of times, thereby have improved manufacturing efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that steel pipe inserts schematic representation of the present utility model.
Fig. 3 is the structural representation that adopts the utility model test Stainless Steel Tube.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: 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 utility model adopts a flat end to reduce gradually to most advanced and sophisticated circle road radius, (Fig. 2 when steel pipe inserts seal ring 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 seal ring, make that the efficient of the hydrostatic test is higher.
As seen from Figure 3: Stainless Steel Tube that C refers to 5 and seal ring 1 surface of contact, simultaneously under the thrust of first securing means, 3 upper push-rods 2 (among the figure: fixing device 4), A of the present utility model, B place (ring-like) is squeezed and reaches the double seal effect.Because adopt progressive diameter reduction, the using effect and the life-span of seal ring strengthen greatly, have reduced the replacing number of times, thereby have improved manufacturing efficiency.
Claims (1)
1. a Stainless Steel Tube is tested the seal ring 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.
