Abstract
The utility model mainly relates to a plastic pipeline bidirectional bayonet jointing apparatus, which mainly comprises a bayonet sleeve which is used to connect two plastic conduits, annular grooves which are opened on the both ends of the bayonet sleeve, elastic sealing rings which are installed in the annular grooves and a baffle plate which is fixed on and connected with the centre part of the bayonet sleeve. Because the sealing rings on the both ends are elastic sealing rings, the plastic conduits can be inserted and connected from the both ends of the bayonet sleeve. A limit stop is used to control the position to the conduits on the both ends. The annular grooves can be opened in the inner side of the bayonet sleeve, and the baffle plate is fixedly connected to the inner side wall of the bayonet sleeve. The annular grooves also can be opened on the outer side of the bayonet sleeve, and the baffle plate can be fixedly connected to the outer side wall of the bayonet sleeve. The elastic sealing rings can adopt hollow circular rubber sealing rings of multitooth rubber sealing rings. The utility model has the advantages of the bidirectional bayonet jointing, convenient operation of connecting plastics underground drainage pipeline, reliable sealing, and can eliminate the inner stress caused by the thermal expansion.
Description
Technical field
The utility model relates to a kind of assembling pipe joint, the two-way socket joint connection set of especially a kind of plastic pipe.
Background technique
Because corrosion-resistant, in light weight, the advantages such as the life-span is long, the smooth non-scaling of tube wall of plastic pipe in recent years, are buried ground draining and blow-off line with heavy-caliber plastic pipe replacement steel pipe and cement pipe conduct in the domestic city construction, effect is remarkable.
The kind of present domestic plastic tube is more, the Placement of tubing also is variation, except that enlarging type tubing adopts the connection of socket joint elastic packing, the connection of non-enlarging type tubing adopts electric smelting, heat-contraction sleeve, rubber ring to add stainless steel Hough modes such as (clips) mostly, and these Placement operations are comparatively complicated.
Summary of the invention
The utility model will solve the shortcoming of existing plastic tube connection set complicated operation, provide a kind of can two-way socket joint, the two-way socket joint connection set of easy construction and reliable sealing plastic pipe.
The technological scheme that its technical problem that solves the utility model adopts.The two-way socket joint connection set of this plastic pipe comprises that mainly one is used to connect the cover of accepting of two plastic pipes, and these two ends of accepting cover have annular groove, and this annular groove is built-in with elastic seal ring; The middle part of accepting cover is fixedly connected with baffle plate.Because the seal ring at two ends is elastic seal rings, plastic pipe can insert from the two ends of accepting cover and connect.Block is used to control the location to the two ends pipeline.
The two-way socket joint connection set of plastic pipe provided by the utility model, described annular groove can be opened in the inboard of accepting cover, and baffle plate is fixedly connected on the madial wall of accepting cover.Annular groove also can be opened in the outside of accepting cover, and baffle plate is fixedly connected on the outer side wall of accepting cover.Elastic seal ring can adopt the round rubber seal ring or the multiple tooth shape rubber seal of hollow, and such seal ring has more elasticity, helps pipeline and inserts.
The effect that the utility model is useful is: the utility model can two-way socket joint, connects the easy construction of plastic underground drainage pipe, and sealing is reliable, can also eliminate the internal stress that plastic pipe is caused by thermal expansion.

Fig. 2 is the utility model embodiment 2 a structural representation;
Fig. 3 is the structural representation of embodiment 1 hollow circular rubber seal cross section;
Among the figure: the 1-plastic pipe, 2-accepts cover, 2-1-annular groove, 3-seal ring, 4-block
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Embodiment 1: as shown in Figure 1, present embodiment comprise one be used to connect two plastic pipes 1 accept cover 2, the socket joint cover adopts stainless steel sleeve.This is accepted on the madial wall at cover 2 two ends and has annular groove 2-1, and this annular groove 2-1 is built-in with elastic seal ring 3, and elastic seal ring 3 adopts the round rubber seal ring of hollows, accepts on the middle part madial wall of cover 2 and is welded with a circle baffle plate 4.Adopt this structure, present embodiment constitutes the two-way socket joint connection set of outer socket joint plastic pipe, and sealing surface is suitable for when pipeline external surface is smooth at the outer wall of tubing.
Embodiment 2: embodiment 2 is with embodiment 1 difference: annular groove 2-1 opens on the outer side wall of accepting cover 2, and elastic seal ring 3 adopts multiple tooth shape rubber seal also to be arranged in the annular groove 2-1, accepts on the middle part outer side wall of cover 2 and is welded with a circle baffle plate 4.Adopt this structure, the two-way socket joint connection set of socket joint plastic pipe in present embodiment constitutes, sealing surface are suitable for when plastic pipe 1 outer surface is rough at the inwall of tubing.
During use, the plastic pipe 1 that need are connected gets final product from accepting the insertion of cover 2 two ends respectively, and is simple to operate.Block 4 gives two plastic pipes 1 spacing.Elastic seal ring 3 can prevent the leaked water in the plastic pipe 1.
