Abstract
The utility model aims to provide a combined type sewer pipe with excellent leak resistance and convenient installation and use. The purpose of the combined type sewer pipe is realized as follows: the combined type sewer pipe comprises a plastic pipe main body, an outer sealing ring and an inner sealing ring, wherein an annular groove is arranged at the inner side of one end of the plastic pipe main body, the outer sealing ring is clipped in the annular groove, and the inner sealing ring is arranged at the inner side of the outer sealing ring. The plastic pipe main body is linear or curved. The combined type sewer pipe has the advantages of simple structure, convenient construction, saved man hour, saved cost, no bonding at the connector and good sealing performance.
Description
Technical field
The utility model relates to a kind of constructional materials, is exactly a kind of combined sewer pipe specifically.
Technical background
At present, the plastic pipe on the building material market, the specification difference, purposes is different.The outdoor water drainage plastics pipe of high building row rainwater, the indoor sewer pipe etc. of being used for, its basic structure is similar, most of serial connection mode that adopts, the sealed against leakage of joint is a key issue, the way that solves is to use fluid sealant bonding at blank area at present.This connected mode not only is difficult to guarantee good seal, and often because bonding not firm and leak, and construction wastes time and energy, and influences the raising of efficiency of construction.Owing to use expensive bonding agent, therefore strengthened estimated cost.
Summary of the invention
The combined sewer pipe that provides a kind of leak resistance good, easy to install is provided the purpose of this utility model.
The purpose of this utility model is achieved in that it is made up of plastic pipe main body 1, exterior seal ring 3 and inner seal ring 2.The inboard of plastic pipe main body 1 one ends is provided with cannelure 4, and exterior seal ring 3 is stuck in 4 li of cannelures, and inner seal ring 2 is arranged on exterior seal ring 3 inboards.Plastic pipe main body 1 can be a linear pattern, also can be shaped form.
A kind of combined sewer pipe of the utility model, simple in structure, man-hour is saved in easy construction, saves cost, and the joint need not be bonding, good seal performance.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of combined sewer pipe of the utility model, it is made up of plastic pipe main body 1, exterior seal ring 3 and inner seal ring 2.The inboard of plastic pipe main body 1 one ends is provided with cannelure 4, and exterior seal ring 3 is stuck in 4 li of cannelures, and inner seal ring 2 is arranged on exterior seal ring 3 inboards.Plastic pipe main body 1 can be a linear pattern, also can be shaped form.A kind of combined sewer pipe of the utility model, its manufacturing process have guaranteed that the tight fit of plastic pipe main body 1, leakproof connect, and when two sections pipes connect, need only the front end that the leading portion pipe is inserted the back segment pipe, can guarantee closely cooperating of two pipes.Because the effect of sealing ring can be accomplished to fit together perfectly no seepage and no leakage.This installation mode, simple, removed making the trouble that sticks with glue from.
