Abstract
The invention discloses a flexible sleeve for plain-wall pipes and relates to the field of pipeline fittings. A plurality of V-shaped grooves are formed in the middle of the flexible sleeve, a socket, a rubber ring groove and a lead-in opening are formed in each of two sides of the flexible sleeve, and the flexible sleeve body is made of a low-density polyethylene material and therefore has favorable axial expanding and bending performance. The flexible sleeve is used together with an elastic seal ring to achieve excellent sealing performance, is used for connecting large-diameter plastic drainage plain-wall pipes, is a multifunctional connecting piece, and can not only adapt to axial stretching and shrinking of plastic pipelines due to expansion caused by heat and contraction caused by cold, but also prevent the connecting parts of the pipelines from disengagement or cracks caused by irregular inclination of the pipelines due to local sinking of a foundation, thereby preventing leakage.
Description
Technical field
The present invention relates to plumbing fitting field, is the linkage of various large-bore plastics draining walled tube.
Background technology
Large-bore plastics draining walled tube at present as urban rainwater, sewage collecting and discharge main pipe and be embedded in underground, owing to usually 5 or 6 tubing being linked into an integrated entity in the current engineering construction of such tubing, the mode connecting tubing mainly adopts thermal shrinkable sleeve connection, Electric thermal smelting belt connects or clamp connection, these three kinds of connected modes all can not adapt to because the ground of support pipeline is because the soil is porous or underground water overflows and sink, cause pipeline commissioning to make connector and bodies splittable or disengaging, cause and leak so that contaminated environment.
Summary of the invention
the leakage caused that certainly falls into that the object of the invention is to solve the existing method of attachment of large-bore plastics draining walled tube causes problem of environmental pollution, for herein is provided a kind of walled tube flexible sleeve as the reliable method of attachment of large-bore plastics draining walled tube, thoroughly solve an above-mentioned difficult problem.
In order to realize above object, the present invention solves its technical barrier and is achieved through the following technical solutions.
A kind of walled tube flexible sleeve, is characterized in that: in the middle of sleeve by multiple V-type groove 4, both sides be respectively equipped with bell and spigot 1, cushion rubber groove 3 with and introducing port 2 etc. form.
described walled tube flexible sleeve is that low-density polyethylene material is made.
described walled tube flexible sleeve, it is characterized in that V-type groove 4 and cushion rubber groove 3 are 60 °, introducing port 2 is 8 ~ 12 °.
hinge structure, advantage of the present invention and beneficial effect are: the unreasonable connection solving large-bore plastics draining walled tube, stop to leak.
Accompanying drawing explanation
Fig. 1 is the sectional view of walled tube flexible sleeve.
Fig. 2 is walled tube flexible sleeve and elastic seal ring sectional arrangement drawing.
Fig. 3 is the sectional view that walled tube flexible sleeve and elastic seal ring, body are installed.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
as shown in Figure 1, the present invention includes: middle multiple V-type groove 4, both sides are respectively equipped with bell and spigot 1, cushion rubber groove 3 and and introducing port 2.
As shown in Figure 2, elastic seal ring 5 is placed in both sides of the present invention cushion rubber groove 3.
as shown in Figure 3, two sections of walled tube 6 insert both sides bell and spigot 1 through introducing port 2 respectively, because the elastic seal ring 5 in V-type groove 4 presses formation closed-loop with the outer wall of walled tube 6, stop water toward external leakage; When body one end sinks, the flexible distortion of multiple V-type grooves 4 in the middle of sleeve is tilted 0 ~ 30 ° to adapt to body, guarantees to close water under severe geological conditions respond well.
Claims (3)
1. a walled tube flexible sleeve, is characterized in that: be respectively equipped with bell and spigot 1, cushion rubber groove 3 and and introducing port 2 by multiple V-type groove 4, both sides in the middle of sleeve.
2. walled tube flexible sleeve according to claim 1, is characterized in that sleeve material is that low-density polyethylene material is made.
3. walled tube flexible sleeve according to claim 1, it is characterized in that V-type groove 4 and cushion rubber groove 3 are 60 °, introducing port 2 is 8 ~ 12 °.
