Compared with the traditional bell and spigot, the shape of the spigot of the bell and spigot pipeline is optimized, the section shape of the rubber ring is changed, the torsional deformation of the rubber ring is avoided, the airtightness is good, and the condition of water leakage is effectively prevented.
Description
Technical Field
The utility model belongs to the municipal works field, in particular to socket pipe socket connection structure.
Background
In present municipal works, socket joint pipeline construction often adopts the rubber circle to place in bell and spigot department and is assisted with cement mortar and touch the area and close water antiseep, but still the condition that the percolating water can appear after socket joint pipeline construction accomplishes sometimes. This situation often occurs because the rubber ring fails to fill the socket gap of the socket pipe. Because the cross section of the existing rubber ring is circular, torsion often occurs in the installation process, twisting deformation can occur in the insertion process of the bell and spigot, a gap is generated, and the bell mouth of the bell and spigot pipeline cannot be well sealed.
Disclosure of Invention
The invention aims to overcome the defects of the background technology and provide a socket connection structure of a socket pipeline.
The invention is realized by the following technical scheme: a spigot and socket connecting structure of a spigot and socket pipeline is characterized in that a first reducing port and a second reducing port are arranged at a spigot of the spigot and socket pipeline, and the diameter of the second reducing port is smaller than that of the first reducing port; the rubber ring is arranged at the second reducing port, and the maximum thickness of the rubber ring is larger than the height difference between the first reducing port and the second reducing port.
Preferably, the cross section of the rubber ring is a right triangle.
Preferably, the angle of the rubber ring towards the bell mouth direction of the socket pipeline is 15-30 degrees.
The invention has the beneficial effects that:
compared with the traditional bell and spigot joint, the invention optimizes the shape of the spigot joint of the bell and spigot pipeline, changes the section shape of the rubber ring, avoids the occurrence of torsional deformation of the rubber ring, has good tightness and effectively prevents the condition of water leakage.

In the figure, 1 is used for inserting a pipeline, 2 is used for a first reducing port, 3 is used for a second reducing port, and 4 is used for a rubber ring.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The structure of the spigot and socket pipe 1 is shown in figure 3, the spigot is designed as a reducing mouth, and the reducing mouth at the spigot is smaller than the diameter of the spigot and socket pipe 1. The invention improves the socket of the prior socket pipeline 1, and the bell mouth structure of the socket pipeline 1 is not changed. The invention designs the spigot of the prior spigot-and-socket pipeline 1 into two reducing ports, namely a first reducing port 2 and a second reducing port 3, wherein the diameter of the first reducing port 2 is the same as that of the prior spigot-and-socket pipeline 1, and the diameter of the second reducing port 3 is smaller than that of the first reducing port 2.
The rubber ring 4 is also improved in the structure of the existing rubber ring 4 at the socket, the section of the rubber ring 4 is designed to be wedge-shaped, the rubber ring 4 is sleeved at the second reducing port 3, and the maximum thickness of the rubber ring 4 is larger than the height difference between the first reducing port 2 and the second reducing port 3.
In order to prevent the rubber ring 4 from twisting to the maximum extent during socket joint, the cross section of the rubber ring 4 is preferably a right triangle, and the right end is located at the junction of the first reducing port 2 and the second reducing port 3 during installation.
In order to make the rubber ring 4 contact with the bell mouth of the socket pipe 1 better to fill the gap, the inclined angle of the rubber ring 4 towards the bell mouth of the socket pipe 1 is preferably between 15 and 30 degrees. The smaller the angle of the inclined plane is, the better the inclined plane can be filled into a gap between the socket and the socket.
During construction, the rubber ring 4 is sleeved on the position of the second reducing port 3 of the spigot, the right-angle end of the rubber ring 4 is tightly attached to the inner edge of the second reducing port 3, then the spigot is taken up and inserted into the bell mouth for butt joint, the bell mouth jacks the rubber ring 4 towards the opposite direction of installation of the spigot-and-socket pipeline 1 along with the insertion of the spigot in the plugging process, and because the step exists between the second reducing port 3 and the first reducing port 2, the rubber ring 4 cannot move along the jacking direction but can extend and deform towards the jacking direction to be filled into a gap. On the other hand is right angled triangle because of 4 cross-sections of rubber circle, 4 whole unable productions of rubber circle twist reverse in the installation, so the bellmouth can firmly crowd rubber circle 4, the right angle end of rubber circle 4 warp left and extends into the gap of kneck in, the right-hand member of rubber circle 4 stretches into in the gap of kneck, the at utmost has reduced the gap between 1 socket of socket pipe way and the bellmouth, can not produce also that rubber circle 4 warp the gap that produces because of rubbing, the effectual condition that prevents the percolating water. The above is for ease of understanding that the left or right is left or right on figure 1.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
