Abstract
The utility model discloses a sealing ring of polyethylene double-wall bellows; wherein, the section of the sealing ring is designed into a front and back tracks jointly sealing; a bulge which is like the dorsal fin of fish is arranged at the upper side of the utility model; a bulge, the left side of which is basin-shaped and the right side of which is nail-shape, is arranged at the lower side. The utility model has the advantages of increasing the sealing length, and taking the effects of preventing overturning and strengthening the sealing.
Description
Affiliated technical field
The utility model relates to a kind of seal for pipe joints figure, the seal ring that particularly a kind of polyethylene double-wall corrugated pipe uses.
Background technique
Polyethylene (PE) double-wall corrugated pipe is a kind of plastic construction wall pipe, is mainly used in blowdown, draining field, and the connection of this tubing generally adopts the flexible seal ring socket joint to connect.And that the CONCENTRIC REDUCER of import equipment connects seal groove is very shallow, add the softer construction earthing of polythene material after pipe deforming big, upset and seepy question often appear inserting in the seal ring that matches with it, this has become the bottleneck that the restriction bellows is applied.
The model utility content
The technical problems to be solved in the utility model provides a kind of seal ring of polyethylene double-wall corrugated pipe of energy reliable sealing socket joint Placement.
The technological scheme that its technical problem that solves the utility model adopts is: the conjuncted sealing of two pass before and after the seal ring Cross section Design is become, the projection of establishing twice such as fish dorsal fin up, below then be the projection that a left side as basin shape basis are right as follow closely shape.
The beneficial effects of the utility model are: after being designed to the conjuncted sealing of two pass, the whole seal length of pipeline obtains increasing, and during when pipeline connects the φ angle deviation is arranged and at the pipeline compressive deformation, sealing effect is highly desirable.In addition, be designed to conjuncted after, two seal grooves check and balance, and play the effect that prevents to overturn and strengthen sealing effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model sectional structure schematic representation;
Fig. 2 is the utility model partial structurtes schematic representation in connecting use.
1. seal rings among the figure, 2. double-wall corrugated pipe, 3. double-wall corrugated pipe.
Embodiment
As shown in Figure 1, the utility model becomes the conjuncted sealing of front and back two pass with the Cross section Design of seal ring (1), the projection of establishing twice such as fish dorsal fin up, and a left side is high right low; Below then be the projection that a left side as basin shape basis are right as follow closely shape.
As shown in Figure 2, the utility model at polyethylene double-wall corrugated pipe (2) with during polyethylene double-wall corrugated pipe (3) socket joint is connected, the twice of top such as the projection of fish dorsal fin are extruded distortion and are close to tube wall, and a left side, below is then distinguished in the respective grooves of firm insertion bellows as the projection of the right side, basin shape basis as nail shape.Adopt above structure, the conjuncted seal length that both increased of two seal grooves, two seal grooves check and balance and have strengthened the fastness of seal ring (1) in wave groove, play the effect that prevents to overturn and strengthen sealing effect.
Claims (2)
1. polyethylene double-wall corrugated pipe seal ring is characterized in that: the conjuncted sealing of two pass before and after the seal ring Cross section Design becomes, the projection of establishing twice such as fish dorsal fin up, below then be the projection that a left side as basin shape basis are right as follow closely shape.
2. polyethylene double-wall corrugated pipe seal ring according to claim 1 is characterized in that: the projection of twice such as fish dorsal fin is established in described top, for left high right low.
