Abstract

The utility model discloses a seal ring which is characterized in that the seal ring comprises a tubular body (8), wherein a raised step (81) is arranged at one end of the tubular body (8), and a plurality of raised rings (82) are arranged on the tubular body (8). The seal ring has simple structure and good sealing effects and can be effectively used for sealing the pipe fittings in the high temperature and high pressure environment.

Description

A kind of seal ring
Technical field
The utility model relates to a kind of seal ring, especially for the seal ring of solar water heater pipe fitting sealing.
Background technique
Common pipe fitting connects, and needs a seal ring with the enhanced leaktightness effect usually.But present employed seal ring mostly is a simple rubber ring greatly, and for common water pipe, sealability is enough.But as the Sealing of solar water heater, owing to characteristics such as high temperature and pressure in the pipe are bigger, common seal ring can not reach required sealing effect.
The model utility content
The purpose of this utility model is, a kind of seal ring is provided.It simple in structure, and good sealing effect can be effective to the pipe fitting sealing of high temperature and hyperbaric environment.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of seal ring is characterized in that: comprise tubular body, an end is provided with the step of projection on the tubular body, also is provided with a plurality of raised rings on the tubular body.
In the aforesaid seal ring, described raised ring is located at the outer surface of tubular body.
In the aforesaid seal ring, described raised ring is located at the internal surface of tubular body.
Compared with prior art, the utility model can be when pipe fitting connects by on the tubular body of seal ring raised ring being set, the effect of banding is provided repeatedly, sealing effect is with respect to common smooth seal ring better effects if, and under high temperature and high pressure environment, still keeps good sealability.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment 1: a kind of seal ring, as shown in Figure 1, comprise tubular body 8, and an end is provided with the step 81 of projection on the tubular body 8, also is provided with a plurality of raised rings 82 on the tubular body 8.Described raised ring 82 is located at the outer surface of tubular body 8.Inducing in pipe 4 and being connected of heat-exchange tube 2 of separated type solar water heater, as shown in Figure 3, seal ring of the present utility model is inserted induce pipe 4 earlier, offset with inducing pipe 4 mouths of pipe until projection step 81, insert heat-exchange tube 2 again.
Embodiment 2: a kind of seal ring, as shown in Figure 2, comprise tubular body 8, and an end is provided with the step 81 of projection on the tubular body 8, also is provided with a plurality of raised rings 82 on the tubular body 8.Described raised ring 82 is located at the internal surface of tubular body 8.Inducing in pipe 4 and being connected of heat-exchange tube 2 of separated type solar water heater, as shown in Figure 4, seal ring of the present utility model is inserted induce pipe 4 earlier, offset with inducing pipe 4 mouths of pipe until projection step 81, insert heat-exchange tube 2 again.
