Abstract
The utility model relates to the sealed ring of a plain-end pipe for a sewer pipeline, composed of a sealed outer ring, an interface sealed cushion integrally connected with the sealed outer ring, and a minor sealed ring cushion integrally connected with the interface sealed cushion. The sealed ring is made of elastic material, such as rubber, or rubber plastic, etc. The utility model has the advantages of reliable seal, convenient construction, low cost, etc., and the bent interface of a pipeline is difficult to leak.
Description
The utility model relates to a kind of sewer pipe sealing ring.
Adopt flat mouthful of pipe to lay the sewer pipe interface at present and all adopt pitch prill and malthoid sealing.Sealant is generally five layers, and wherein the two-layer pitch prill coating of malthoid is alternately arranged for three layers, and sealant external application concrete for making waterproofing course is reinforced.This encapsulating method and structure be cost height, long construction period not only, and engineering quantity is big, labour intensity is big and the reliability of sealing is difficult for guaranteeing.Especially change and sink or drum when protruding when the pipeline ground is subjected to external force effect or geological hydrology condition, pipeline bends, generation extruding and stretching action and sealant and tube wall stripping channel are leaked between sealant and tube wall.Because there are above-mentioned weak point in existing encapsulating method and hermetically-sealed construction, so more and more incompatibility instructions for use.
It is low that the purpose of this utility model provides a kind of cost, and the pipe joint seal construction is easy and simple to handle, and the cycle is short, flat mouthful of seal of tube circle of reliable sealing sewer pipe.
Flat mouthful of seal of tube circle of sewer pipe by sealed outer ring, with the whole sealing joint pad that is connected of sealed outer ring, the sealing ring pad of paying that is connected with sealing joint padding body constitutes, and sealed outer ring, sealing joint pad, pays the manufacturing of sealing ring pad employing elastomeric material integral body.
When flat mouthful of seal of tube circle of sewer pipe was used for flat mouthful of interface tube sealing of sewer pipe, sealed outer ring and two pipeline section pipe outside wall surface were closely pasted and are touched, thereby the sealing joint pad, paid a sealing ring pad and be positioned between two pipeline section end faces and touch with the end face subsides pipe joint is sealed.
The further improvement of flat mouthful of seal of tube circle of sewer pipe is that the interior collar extension place of sealing joint pad of sealing ring has the sealing joint structure, a kind of structure of sealing joint structure is that collar extension has the whole sealing inner ring that connects in the sealing joint pad, and sealing inner ring wall and tube chamber wall closely pasted and touch when sealing was used.
The another kind of structure of the sealing joint structure at collar extension place is that interior collar extension has the bivalve formula that is connected with sealing joint padding body to seal lobe while still alive in the sealing joint pad, separately compressing subsides under pressure with manifold pressure rising sealing flap valve when sealing is used touches on the tube chamber wall, thereby the sealing function at enhanced tube pipeline joint place has improved the sealing reliability of interface antiseep.
Further the improving that sewer pipe is put down mouthful seal of tube circle is with pair sealing ring pad corresponding position the hugging that adapts with pair sealing ring pad shape to be arranged on sealing joint pad pad face, the adapter back is in following pair of sealing ring pad hugging of pipe end face extruding and sealing joint pad and the subsides of two pipe end faces are touched, pay sealing ring pad and under elastic reaction, compress and contact, thereby further strengthened sealing function with the pipe end face.
Flat mouthful of seal of tube coil structures of sewer pipe is simple, easy to manufacture, and seal construction is easy and simple to handle, thereby short construction period, and cost is low, and is few with material, can reduce the seal construction expense significantly.Use sealing ring carry out the pipe joint sealing can be simultaneously with the gap sealing of the easy generation seepage at pipe joint place, thereby sealing is reliable.Sealing ring adopts elastomeric material to make, and pipeline bends, sealing ring elastic deformation thereupon, thereby still can keep good sealing state, and pipeline is difficult to be leaked.
Accompanying drawing is embodiment of the present utility model, further specifies the utility model below in conjunction with embodiment.
Fig. 1 is flat mouthful of seal of tube circle cross-section structure of sewer pipe.
Fig. 2 has whole flat mouthful of seal of tube circle cross-section structure of sewer pipe that connects the sealing inner ring.
Fig. 3 has the whole cross-section structure that connects the flat mouthful of seal of tube circle of sewer pipe of sealing flap valve.；
Flat mouthful of seal of tube circle of sewer pipe is ring shape, adopts rubber, rubber and plastic one elastic-like material to make, and its section as shown in the figure.
Flat mouthful of seal of tube circle of sewer pipe is made of sealed outer ring (1), the sealing joint pad (2) that is connected with sealed outer ring integral body and pair sealing ring pad (3) that is connected with sealing joint padding body, (4), when being used for seal for pipe joints, make corresponding hugging on the pipeline section end face, make and pay in the sealing ring pad embedding hugging.As shown in Figure 2, by sealed outer ring (5), sealing joint pad (6), pay in the sealing joint pad of the sealing ring that sealing ring pad (7) and (9) integral body connects and composes collar extension place integral body and be connected with and seal inner ring (8).Sealing inner ring and tube chamber wall closely paste and touch when connecing the deferent sealing joint.
For the sealing instructions for use of the sewer pipe that adapts to different tube diameters, sealing ring can be made into the sealing ring of cross section structure as shown in Figure 3.As shown in Figure 3, be connected with the sealing flap valve that is made of the flap valve that separates (14) and (15) by collar extension place integral body in the sealing joint pad of sealed outer ring (10), sealing joint pad (11), pair sealing ring that sealing ring (12) and (17) integral body is formed by connecting, on the sealing joint pad pad face and pair sealing ring pad corresponding position has and pays a hugging (13) and the hugging (16) that sealing ring pad adapts to.Pipe joint two pipe end faces pasted with the sealing joint pad and touch when sealing was used, and paid a sealing ring pad and were pressed in the hugging, and pair sealing ring pad compresses to contact with the pipe end face under the elastic force effect and makes the pipe joint good seal.When in the pipeline pressure being arranged, two flap valves separately closely paste to touch to both sides and make pipe joint be difficult for leaking on two tube section ends tube chamber walls under the effect of pipe internal pressure.
Claims (4)
1, flat mouthful of seal of tube circle of a kind of sewer pipe, it is characterized in that being made of sealed outer ring, the sealing joint pad that is connected with sealed outer ring integral body, a pair sealing ring pad that is connected with sealing joint padding body, sealed outer ring, sealing joint pad, pair sealing ring pad adopt the whole manufacturing of elastomeric material.
2, by flat mouthful of seal of tube circle of the described sewer pipe of claim 1, it is characterized in that collar extension has the whole sealing inner ring that connects in the said sealing joint pad.
