Abstract
The invention discloses an O-shaped sealing ring for stainless steel pipe fittings, which is like a circular ring. At least one bump is processed on the inside-diameter surface and the outside-diameter surface along the radial position; and the O-shaped sealing ring for the stainless steel pipe fittings is made of an elastic material of polytetrafluoroethylene. According to the O-shaped sealing ring for the stainless steel pipe fittings, water leakage can be detected during pressure test, so that the shortage can be discovered in time during construction and the hidden danger can be eliminated, therefore, the O-shaped sealing ring for the stainless steel pipe fittings has the advantages of guaranteeing the reliability of construction quality.
Description
Technical field
The present invention relates to a kind of seal ring, especially a kind of stainless steel pipe is used the O RunddichtringO.
Background technique
As everyone knows, the card between the stainless steel pipe is pressed and is connected, and at first is in the U type groove of the end of stainless steel pipe, to place the O RunddichtringO; Stainless steel waterpipe is inserted in the pipe fitting again, press with the instrument card, pipe fitting and water pipe are pressed into hexagon and strong bonded by card; But the O RunddichtringO that these pipe fittings adopt is because its external diameter and inside diameter surface all are smooth-going, in work progress; Press operation if forget card; Then in the process of later stage pressure testing, short-term can not leaked in the time, but had sealing hidden danger greatly.
Summary of the invention
The problem that the present invention will solve is the deficiency that overcomes in the background technique, provides a kind of stainless steel pipe to use the O RunddichtringO, and this stainless steel pipe is used the O RunddichtringO; External diameter surface has convexity in it, in work progress, presses operation if forget card; When the later stage pressure testing, can in time find the situation of leaking.
For addressing the above problem, the present invention takes following technological scheme:
A kind of stainless steel pipe of the present invention is used the O RunddichtringO, is circular, is processed with at least one convexity respectively at inside diameter surface and external diameter surface, radially position processing of convexity, and stainless steel pipe is processed by the elastic material teflon with the O RunddichtringO.
A kind of stainless steel pipe of the present invention is used the O RunddichtringO; Because the interior external diameter surface of this O RunddichtringO has convexity, under the situation of not blocking pressure, there is the space in the contact surface between pipe fitting, O RunddichtringO, the water pipe; Can when the pressure testing operation, find the situation of leaking at once; Therefore the deficiency in can in time finding to construct is removed a hidden danger, and has the advantage that ensures reliable construction quality.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of stainless steel pipe of the present invention is used the O RunddichtringO, is circular, is processed with at least one convexity 1 respectively at inside diameter surface and external diameter surface, the radially position processing of the convexity 1 of said inside diameter surface and external diameter surface.
Stainless steel pipe is processed by the elastic material teflon with the O RunddichtringO.
