Abstract
The utility model discloses a rubber seal ring for steel strip tube socket and spigot joint. The rubber seal ring comprises a body. Two or more than two seal rings extend in the same direction on the outer wall of the body, and a gap exists between the adjacent seal rings. According to the rubber seal ring disclosed by the utility model, the seal rings are arranged, the gap exists between the adjacent seal rings, and during the process of inserting the socket of a steel strip tube into a spigot, space for the seal rings to deform is given by the gaps, therefore, the seal rings can largely deform. After installation is finished, the seal rings are tightly contacted with the inner wall of the socket under the proper elastic action of the seal rings. Moreover, a plurality of seal rings are arranged, thus, a multi-layer seal action can be performed, therefore, a very good seal action can be performed by the rubber seal ring disclosed by the utility model.
Description
Technical field
The utility model relates to rubber seal, especially for the rubber seal in the steel band pipe socket joint linkage structure.
Background technique
The steel band pipe mainly is applied in blowdown, the draining, and the steel band pipe mainly comprises steel band reinforced polyethylene spiral ripple pipe and buries the ground steel and mould compound winding waste pipe.Tradition connects the mode of steel band pipe through the realization of hot melt band, though this structure can realize the connection of steel band pipe; Since the steel band pipe generally be embedded in underground; Very inconvenient at underground winding hot melt band, and, in case the immersion of water is arranged; Even the steel band pipe has been connected, its sealability is also bad.For this reason, occurred the linkage structure of spigot and socket type now, both the end at the steel band pipe connected the bellmouth joint, and the other end connects the socket joint; And on the outer surface of socket joint, overlap an O RunddichtringO, during installation, the socket joint is inserted in the bellmouth joint; And through the sealing of O RunddichtringO, though this structure has been brought convenience to installation; Because the amount of elastic deformation of O RunddichtringO is little, therefore, the poor performance of sealing.
Summary of the invention
For solving the technical problem of poor sealing performance, the utility model provides a kind of steel band pipe socket joint to connect and has used rubber seal.
The technological scheme that solves the problems of the technologies described above is: steel band pipe socket joint connects and to comprise body with rubber seal, on the outer wall of body to the seal ring that is extended with on the same direction more than two, have the gap between the adjacent seals ring.
As specializing, the cross section of seal ring is a triangle.
As improvement, body and seal ring are structure as a whole.
The beneficial effect of the utility model is: owing to be provided with seal ring; And have the gap between the adjacent seals ring, be inserted in the bellmouth process at the socket of steel band pipe, the gap has given the space of sealing ring deformation; Therefore; Bigger amount of deformation can take place in seal ring, after installation, seal ring is closely contacted with the bellmouth inwall; In addition,, like this, can play multi-layer sealed effect, therefore, adopt the rubber seal of the utility model structure can play good seal action owing to be provided with a plurality of seal rings.Because seal ring has adopted leg-of-mutton cross section, therefore, in forming process, is convenient in demoulding.Because body and seal ring are structure as a whole, therefore, the intensity of whole seal ring is high, when moulding, also can once accomplish, thereby improve work efficiency.
Description of drawings
Fig. 1 is that steel band pipe socket joint connects the stereogram with rubber seal.
Fig. 2 is that steel band pipe socket joint connects the sectional view with rubber seal.
Fig. 3 is the enlarged view of A.
Fig. 4 is installed to the sectional view on the steel band pipe socket joint linkage structure for rubber seal.
Fig. 5 is the enlarged view of B.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further elaborated.
To shown in Figure 3, steel band pipe socket joint connects with rubber seal and comprises body 1 and seal ring 2 like Fig. 1.Seal ring 2 is made up of plural, is formed with gap 3 between the adjacent seals ring, and all seal rings are to same direction diagonally extending vertically.As shown in Figure 3, the cross section of seal ring is a triangle, certainly, also can be other shape.In order to improve the intensity of rubber seal, and make the rubber seal can once-through, body 1 and seal ring 2 are designed to integrative-structure.
Like Fig. 4 and shown in Figure 5, in use, earlier rubber seal is enclosed within on the socket 4, then socket 4 is inserted in the bellmouth 5 together with rubber seal.
As shown in Figure 5; Owing to be provided with sealing ring 2; And there is gap 3 between the adjacent seals ring; Socket 4 at the steel band pipe is inserted in bellmouth 5 processes; The gap has given the space of sealing ring 2 distortion, and therefore, bigger deflection can take place sealing ring; After installation, sealing ring is closely contacted with the bellmouth inwall; In addition,, like this, can play multi-layer sealed effect, therefore, adopt the rubber seal of the utility model structure can play good sealing function owing to be provided with a plurality of sealing rings.
Claims (3)
1. steel band pipe socket joint connects and to use rubber seal, it is characterized in that: comprise body, on the outer wall of body to the seal ring that is extended with on the same direction more than two, have the gap between the adjacent seals ring.
2. steel band pipe socket joint according to claim 1 connects uses rubber seal, and it is characterized in that: the cross section of seal ring is a triangle.
3. steel band pipe socket joint according to claim 1 and 2 connects uses rubber seal, and it is characterized in that: body and seal ring are structure as a whole.
