Abstract
The utility model relates to a duct joint structure, particularly a sewer pipe joint structure. The utility model is composed of a pipe hoop with an internal splay and internal thread, a rubber sealing ring and a joint; both ends of the rubber sealing ring are provided with a large and a small splay, and the internal openings at both ends of the joint are provided with splays and outside thread; The utility model adopts the thread tightening and the sealing of the rubber sealing ring which is pressed by means of the foreign force. The utility model has the advantages of simple structure, convenient installation, corrosion prevention, low noise and long service life. The intensity of the noise ranges from 43 dB to 48 dB, and conforms to the Chinese standard.
Description
The utility model belongs to the syndeton of pipeline.The joint design that connects usefulness especially for sewer pipe.
It is cylinder iron to manage or the earthenware connection that existing sewer pipe connects, its interface must be tightly connected as adhesive means with cement or other, during this sewer pipe installation fee, take a lot of work, labour intensity greatly, particularly cast iron pipe is perishable, application life is short, and be difficult for sometimes pipeline connection port is obturaged, make sewage outflow easily, contaminated environment.
The utility model at above-mentioned situation designed a kind of have simple in structure, cost is low, easy for installation, the polyethylene sewer pipe joint design of characteristics such as long service life.
The utility model is achieved by following manner: a kind of polyethylene sewer pipe joint design, comprise pipe collar, rubber seal, pipe and joint, the utility model be in the termination is had, splay, the pipe collar of internal thread is enclosed within on the pipe, two ends of packing into have the rubber seal of splaying, precession two end internal orifices have splay, externally threaded joint, played easy for installation, save time, laborsaving, safe and reliable and have the polyethylene sewer pipe joint of effect such as anticorrosion, be current desirable sewer pipe product.
The utlity model has simple in structure, cost is low, characteristics such as in light weight, and be widely used in pipe and be connected with sewerage systems such as threeway with elbow, pipe with pipe, pipe.
Accompanying drawing is the utility model structural representation;
Among the figure: pipe collar 4, rubber seal 3, joint 1, pipe 2.
The utility model most preferred embodiment, as shown in the figure, a kind of polyethylene sewer pipe joint design comprises pipe collar 4, pipe 2, rubber seal 3 and joint 4.The utility model is that the pipe collar 4 that will have internal thread and splay is enclosed within on the pipe 2, and two ends of packing into have the rubber seal 3 that size is splayed, put into the two end internal orifices externally threaded joint 1 of splaying then, make rubber seal 3 splay greatly and splaying of joint 1 internal orifice matches, it is splayed for a short time and splaying of having of pipe collar 4 matches, said pipe 2, pipe collar 4 and joint 1 are to mould the type of making by injection machine, said pipe collar 4 at first is inserted on the polyethylene pipe 2, the two ends of packing into have the rubber seal 3 of splaying, joint 1 is contained on the pipe head 2, precession pipe collar 4 is tightened it then, borrow external force effect extruding make on its pipe collar 4 splay with rubber seal 3 on the comprehensive engagement of splaying for a short time, simultaneously on the rubber seal 3 splay greatly and the two ends internal orifice has the joint comprehensive engagement of splaying, reach the purpose that is fastenedly connected.
The utility model can go out large, medium and small all size series of products according to instructions for use and condition different designs, to satisfy the different requirements of using of user.
