Helical fissure pipe rubber ring
Technical field
The present invention relates to the pipe fittings field, especially relate to a kind of helical fissure pipe rubber ring.
Background technique
The outer wall form of existing buried pollution discharge pipeline is varied, as the helical fissure pipe of a kind of outer wall around the spiral steel bar, perhaps other outer walls have the bellows of spiral lines, when bellows insert being connected pipe box, utilize when connecting pipe box a plurality of bellowss being coupled together, the way of cement injection is adopted in bellows and the sealing that is connected pipe box usually, though reached the effect of sealing, but the cement injection complicated operation is not quick detachable, time-consuming.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of helical fissure pipe rubber ring is provided, when the helical fissure pipe is connected with the connecting tube cover, both are well sealed, and easy installation and removal is simple.
The technical solution adopted for the present invention to solve the technical problems is: a kind of helical fissure pipe rubber ring, be used for the helical fissure pipe and be connected being tightly connected of pipe box, the inwall of rubber ring has one or more the thread groove that matches with the spiral lines of helical fissure pipe outer wall, and the maximum diameter of rubber ring outer ring adapts with the internal diameter that is connected pipe box.The rubber ring material can adopt General Purpose Rubber or meet the swollen cushion rubber that rises of water.
Further, the outer ring of described rubber ring has the guiding conical surface.
The invention has the beneficial effects as follows: inwall of the present invention has the thread groove that the spiral lines with helical fissure pipe outer wall matches, and the maximum diameter of outer ring adapts with the internal diameter that is connected pipe box.The helical fissure pipe at first puts rubber ring, because the rubber ring inwall has the thread groove that matches with the spiral lines, therefore, rubber ring and helical fissure pipe can be good at being tightly connected, the rubber ring outer ring be connected pipe box and adapt, therefore, rubber ring be connected pipe box and also can well be tightly connected.And, utilize rubber ring to be connected and sealed, on the one hand fabricating cost is lower, on the other hand, mounts and dismounts all more conveniently, and the repair and replacement of helical fissure pipe are also convenient.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention;

Fig. 3 is first embodiment's of invention a use schematic representation;
Fig. 4 is the sectional drawing of second embodiment when using of invention;
Fig. 5 is second embodiment's of invention a use schematic representation;
Wherein: 1. helical fissure pipe 2. connects pipe box, 3. rubber ring, 4. thread groove.
Embodiment
Helical fissure pipe rubber ring as shown in Figure 1, have and be used for the rubber ring 3 that helical fissure pipe 1 and connecting tube 2 are tightly connected, helical fissure pipe 1 outer wall has the spiral lines, rubber ring 3 inner rings are inserted in helical fissure pipe 1 outer ring, the inwall of rubber ring 3 has the thread groove 4 that matches with the spiral lines of helical fissure pipe 1 outer wall, and the maximum diameter of rubber ring 3 outer rings adapts with the internal diameter that is connected pipe box 2.
Rubber ring 3 outer rings have the guiding conical surface, and its cross section is taper, and the helical fissure pipe 1 easier insertion that puts rubber ring 3 connects pipe box 2.
Shown in Figure 3 as Fig. 2, first embodiment of the present invention, the spiral pipeline of helical fissure pipe 1 outer wall is rarer, and rubber ring 3 inwalls have a thread groove 4 that matches with the spiral lines of helical fissure pipe 1 outer wall.The notch of thread groove 4 embeds the part that spiral pipeline epirelief rises, and the projection of thread groove 4 sides matches with the groove of spiral pipeline, makes helical fissure pipe 1 and rubber ring 3 be tightly connected.
Shown in Figure 5 as Fig. 4, second embodiment of the present invention, the spiral pipeline of helical fissure pipe 1 outer wall is closeer, and rubber ring 3 inwalls have two thread grooves 4 that match with the spiral lines of helical fissure pipe 1 outer wall.The notch of thread groove 4 embeds the part that spiral pipeline epirelief rises, and the projection of thread groove 4 sides matches with the groove of spiral pipeline, makes helical fissure pipe 1 and rubber ring 3 be tightly connected.
To sum up, helical fissure pipe 1 puts rubber ring 3 earlier, and rubber ring 3 is tightly connected with helical fissure pipe 1, and helical fissure pipe 1 inserts together with rubber ring 3 and connects pipe boxes 2, rubber ring 3 be connected pipe box 2 and be tightly connected.Utilize rubber ring 3 to be connected and sealed, on the one hand fabricating cost is lower, on the other hand, mounts and dismounts all more conveniently, and the repair and replacement of helical fissure pipe 1 are also convenient.
