Description

Technical Field

[0001] The utility model relates to the technical field of rainwater and sewage pipe networks, in particular to a fixed joint of a rainwater and sewage pipe network. Background Art

[0002] The rainwater and sewage pipe network is a pipe structure composed of several pipes, usually set underground, used to circulate rainwater and transport it to a designated location. However, the length of the pipe is limited, so every two pipes need to be connected and fixed by a fixed joint;

[0003] However, the existing fixed joints of rainwater and sewage pipe networks have the problem of poor connection tightness. The connection strength between the pipe network pipes and the fixed joints is poor, which is prone to risks such as leakage and detachment. In addition, the traditional fixed joints will increase the water flow resistance between the two pipes, thereby affecting the water flow speed and reducing the drainage efficiency.

[0004] To this end, the present application provides a fixed joint for a rainwater and sewage pipe network. Utility Model Content

[0005] The purpose of the utility model is to provide a fixed joint for a rainwater and sewage pipe network, which can effectively solve the problem of poor connection tightness of the fixed joints of the rainwater and sewage pipe network. The connection strength between the pipe network pipe and the fixed joint is poor, and it is easy to have risks such as leakage and detachment. Moreover, the traditional fixed joint will increase the water flow resistance between the two pipes, thereby affecting the water flow speed and reducing the drainage efficiency.

[0006] The utility model is achieved through the following measures:

[0007] A rainwater and sewage pipe network fixed joint, characterized in that it comprises a first fixed joint and a second fixed joint, the first fixed joint and the second fixed joint are both fixedly mounted with a connection plate on their exteriors, and the connection plate is evenly provided with a plurality of mounting holes along the circumference, one end of the first fixed joint is provided with a sub-head, and one end of the second fixed joint is provided with a female head matched with the sub-head;

[0008] The periphery of the first fixing joint and the second fixing joint is provided with a locking structure, and the locking structure includes a flange and a cone sleeve, the cone sleeve is fixedly connected to one side of the flange, and the flange is provided with a plurality of mounting holes 2 that match the mounting holes 1.

[0009] The specific features of the utility model also include:

[0010] The outer center positions of the first fixing joint and the second fixing joint are both set in a conical shape, and the taper of the conical portion of the first fixing joint and the second fixing joint is the same as the taper of the cone sleeve. The conical portion of the first fixing joint and the second fixing joint can cooperate with the cone sleeve. When the cone sleeve is installed and fixed, it can cooperate with the cone portion to squeeze the pipe of the rainwater and sewage pipe network, so that the pipe installation strength is higher;

[0011] During installation, bolts are passed through the first and second mounting holes on both sides for fixed installation.

[0012] Spiral blades are installed on the inner sides of the first fixing joint and the second fixing joint. The spiral blades can form vortices in the water flow process, thereby improving the water flow efficiency.

[0013] The inner wall of the cone sleeve is provided with two groups of grooves, and first rubber rings are placed inside the two groups of grooves. The two groups of the first rubber rings can play a role in squeezing the pipes outside the first fixed joint and the second fixed joint, thereby improving the connection strength between the pipes and the first fixed joint and the second fixed joint.

[0014] An annular groove is provided on one end surface of the sub-head, a second rubber ring is placed inside the annular groove, and the annular groove cooperates with the second rubber ring. After installation, the second rubber ring can be deformed under pressure, thereby improving the sealing performance.

[0015] An encryption groove is provided at the center of the female head, and the encryption groove is adaptively matched with the sub-head. The sub-head is inserted into the interior of the female head, which can effectively improve the connection sealing between the first fixing joint and the second fixing joint.

[0016] The beneficial effects of the utility model are:

[0017] By setting a cone sleeve in conjunction with a flange, a cone portion is set on the outside of the first fixed section and the second fixed section, and the taper is kept the same as that of the cone sleeve. During installation, by reducing the distance between the flange and the connecting plate, the cone sleeve can squeeze the external pipe outside the first fixed section and the second fixed section, effectively increasing the connection strength between the rainwater and sewage pipe network pipes and the first fixed section and the second fixed section.

[0018] By arranging the sub-head and the female head in cooperation with the second rubber ring, the first fixing joint and the second fixing joint are plug-connected through the sub-head and the female head, which can effectively improve the connection sealing and reduce leakage.

[0019] By providing the spiral blades, when the water flows through the first fixed section and the second fixed section, the spiral blades can play a guiding role, so that the water flows in a spiral manner, thereby forming a vortex and improving the water flow efficiency.
