Abstract
Disclosed is a seal ring, which belongs to the PE same-floor drainage pipeline system technology field. The seal ring is composed of a seal ring main body, and is characterized in that seal teeth are arranged in the inner ring of the seal ring main body in matched way, and friction teeth are arranged in the outer ring of the seal ring main body in matched way. The seal ring can provide a reliable and convenient connecting technology between the pipes and the expansion joints in the PE same-floor drainage pipeline system, and can perfectly solve the problem that the reliability is poor and the water leakage happens easily in traditional seal ring, and the service life of the seal ring can be prolonged.
Description
Technical field
The utility model belongs to the technical field of seal ring, is specifically related to realize in a kind of co-layer draining pipe-line system the seal ring that tubing is connected with the expansion slip joint.
Background technique
In recent years, along with the progressively raising of people's living standard, the co-layer draining pipe-line system new technology that is widely used in Europe some heavy constructions application that also takes the lead in having obtained at home is as airport, theater and some high-grade buildings.Because the successful Application of co-layer draining pipe-line system new technology in these heavy constructions is developed same floor wastewater discharge technique and popularization widely.In the co-layer draining pipe-line system, tubing and expansion slip joint all are the Placements that adopts the conventional seals circle at present, though certain effect is arranged, reliability is relatively poor, leak easily, and working life are short.
The model utility content
At the above-mentioned problems in the prior art, the utility model purpose is to provide a kind of technological scheme of seal ring.
Described a kind of seal ring comprises the seal ring main body, it is characterized in that the inner ring of seal ring main body is equipped with the sealing tooth, and the outer ring of seal ring main body is equipped with friction teeth.
Described a kind of seal ring is characterized in that described sealing tooth is two trapezoid shapeds.
Described a kind of seal ring is characterized in that described friction teeth is four tang shapes.
Described a kind of seal ring is characterized in that described seal ring main body, friction teeth and sealing tooth are one-body molded.
Above-mentioned a kind of seal ring provides in the co-layer draining pipe-line system between the tubing and expansion slip joint reliably, interconnection technique easily, the problem of well solved conventional seals circle poor reliability, leaking easily, and prolonged working life of seal ring.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross section structure schematic representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
A kind of seal ring comprises seal ring main body 1, and the inner ring of seal ring main body 1 is equipped with the sealing tooth 3 of two trapezoid shapeds, and the outer ring of seal ring main body 1 is equipped with the friction teeth 2 of four tang shapes, and seal ring main body 1, friction teeth 2 and sealing tooth 3 are one-body molded.
When connecting tubing and expansion slip joint, earlier seal ring main body 1 to be put in the expansion slip joint, the forward (FWD) that then tubing interted has in the expansion slip joint of seal ring main body 1 fixing getting final product.
