Abstract
The utility model discloses a plastic socket and spigot joint for drain pipes, which is characterized in that the plastic socket and spigot joint includes a tubular main body, wherein the diameters of openings at two ends of the main body are different, and the end with the smaller diameter is a welding end; an annular sealing gasket is arranged inside the main body; and the sealing gasket and pipe ends inserted into the two ends of the main body form end surface sealing. The utility model has benefits that the joint is easy to manufacture; for plastic drain pipes, the plastic socket and spigot joint can be directly welded and mounted at one end of one plastic drain pipe in a factory, and another plastic drain pipe just needs to be inserted into the plastic socket and spigot joint during the assembly in a building site, therefore, the connecting parts of the two drain pipes form end surface sealing connection with the annular sealing gasket, the whole assembly process is simple and efficient, the connection has good sealing effect and the joint can serve for a long time.
Description
Technical field
The utility model relates to municipal drainage pipe field, especially for the waste pipe plastics bell and spigot joint that connects waste pipe.
Background technique
Mostly existing plastic drain-pipe is when connecting to connect by thermal shrinkable sleeve or Electric thermal smelting belt, such Placement need be provided with heating plant at the construction field (site), the problem of leaking appears in operation inconvenience in the work progress, and after long-time use the, heat-shrink tube joint easily.
For this reason, people have proposed a kind of mode of the embedded annular expansion waterstop of sleeve pipe that adopts as the bell and spigot joint of waste pipe plastics.Though the bell and spigot joint of this waste pipe plastics is easy for installation, sealing effect is bad, and when inner pipe water pressure increased, the water capacity easily spilt from the contacting point between annular expansion waterstop and the tube outer wall.
The model utility content
The purpose of this utility model is: provide a kind of waste pipe plastics bell and spigot joint easy to connect, good sealing effect of using at the deficiencies in the prior art.
The technical solution of the utility model is: the bell and spigot joint of a kind of waste pipe plastics, it is characterized in that: the main body that comprises tubulose, the diameter difference of main body both ends open, wherein the end that diameter is little is a welding ends, in body interior a Gask-O-Seal is arranged, sealing gasket forms end face seal with the tube end that is inserted by the main body two ends.
Supplementary technology scheme of the present utility model is as follows: preferably, described body interior has a step, and Gask-O-Seal and step are adjacent, and the Gask-O-Seal outer is fitted in the main body inboard.
Preferably, in the inboard large diameter end inboard of main body annular protrusion is arranged.
Preferably, annular expansion waterstop is installed between annular protrusion.
Preferably, described main body is the body that there is the ring seal space tube wall inside.
The beneficial effects of the utility model are: joint is easily made; For plastic drain-pipe, the plastics bell and spigot joint can be in factory directly welded and installed at an end of plastic drain-pipe, only another plastic drain-pipe need be inserted the plastics bell and spigot joint when assembling in the building site gets final product, the attachment portion of two waste pipes forms end face seal with Gask-O-Seal and is connected, whole assembling process is simply efficient, and the joint good sealing effect, long service life.
Description of drawings
The utility model will illustrate that wherein: Fig. 1 is the sectional view of the utility model waste pipe plastics bell and spigot joint specific embodiment by example and with reference to the mode of accompanying drawing; Fig. 2 is the schematic representation of waste pipe plastics shown in Figure 1 bell and spigot joint when connecting waste pipe.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model 1, as shown in Figure 1, the bell and spigot joint of a kind of waste pipe plastics, the main body 1 that comprises tubulose, the diameter difference of main body 1 both ends open, wherein the end that diameter is little is a welding ends, in body interior a Gask-O-Seal 4 is arranged, there is a step main body 1 inside, and Gask-O-Seal and step are adjacent, and Gask-O-Seal 4 outers are fitted in the main body inboard.Sealing gasket 4 forms end face seal with the tube end that is inserted by main body 1 two ends.
In order to increase the sealing between the pipe, can annular expansion waterstop 5 be installed, as shown in Figure 2 between annular protrusion annular protrusion 3 being arranged in the inboard large diameter end inboard of main body.
For intensity and the weight reduction of strengthening bell and spigot joint, described bell and spigot joint main body 1 is the body that there is ring seal space 2 tube wall inside.
As shown in Figure 2, two plastic tubes connect by bell and spigot joint, and one of them plastic tube is welded on the welding ends of bell and spigot joint, and the end of another plastic tube contacts with sealing gasket and forms end face seal.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (5)
1. waste pipe plastics bell and spigot joint, it is characterized in that: comprise the main body of tubulose, the diameter difference of main body both ends open, wherein the end that diameter is little is a welding ends, in body interior a Gask-O-Seal is arranged, sealing gasket forms end face seal with the tube end that is inserted by the main body two ends.
