Embodiment 1
[0040] see figure 1 , figure 2 with image 3 .
[0041] A method for manufacturing a pipe joint mainly includes the following steps:
[0042] Step 1: Use a rubber extruder to make cylindrical rubber ring 1 and vulcanize it with a vulcanizer;
[0043] The internal structure of the rubber ring 1 is centerline symmetrical. The center of the rubber ring 1 has a trapezoidal positioning block 11 protruding inward. The trapezoidal bottom edge of the positioning block 11 extends along the inner wall of the rubber ring 1 to form a straight The section 12 then extends to the outer wall and both ends of the rubber ring 1, and then extends along the inner wall of the rubber ring 1 to form a sealing lip side wall 13. The sealing lip side wall 13 is provided with a center line toward the center of the rubber ring 1. 5 and the sealing lips 14, 15, 16 extending in the direction of the axis of the rubber ring 1. The sealing lip 16 at the end of the rubber ring 1 has a funnel-shaped inclined surfac...

Abstract
The invention discloses a pipe-joint manufacturing method and a pipe joint. The method comprises the following steps: 1, a rubber ring (1) is manufactured and vulcanized, wherein the inside of the rubber ring (1) is provided with a positioning block (11), a straight section (12), sealing lips (14, 15 and 16) and an inclined plane (17), and the rubber ring (1) is provided with a center line (5) towards the rubber ring (1) and a dovetail groove (19) of which two ends are in a dovetail-groove shape; 2, the rubber ring (1) is arranged on a die and coated with adhesive; 3, glass fiber soaked in epoxy resin is wound on the rubber ring to form a glass-fiber wound layer (2); 4, chopped felt continues to be wound on the rubber ring; 5, the surface of polyester is wound in a layer of felt and then is cut off, so as to form the pipe joint; 6, the pipe joint is heated and solidified for one hour at a temperature between 40 and 90 DEG C; and 7, demolding is performed so as to finish manufacturing the pipe joint. The invention provides the pipe-joint manufacturing method which can not suffer from the trouble that the diameter increase of one end of a pipeline for manufacturing a pipeline linking causes the increase of pipeline manufacturing difficulty, the difficulty in transportation and installation and the increase of manufacturing cost, can manufacture, transport and install the pipe joint very easily, realizes pipeline connection, and reduces engineering cost.
Description
Technical field [0001] The invention relates to an improvement of an urban underground pipeline structure in municipal construction, in particular to an improvement of an urban underground pipeline pipe joint structure. Background technique [0002] At present, in municipal construction, urban underground pipelines, including the supply of drinking tap water, the discharge of domestic sewage and rainwater, and the supply and discharge of clean reclaimed water and seawater, generally use large pipelines. Said pipeline adopts steel pipe, cast iron pipe, plastic pipe, concrete pipe or glass steel pipe. For the connection between the pipe and the pipe, the diameter of one end of the pipe is enlarged to make a pipe sleeve that can be sleeved on another pipe. The pipe is inserted into the end with the pipe sleeve, and the inside of the pipe sleeve is inserted Set a sealing ring between the pipes. It is very difficult to manufacture such pipes with pipe sleeves, difficult to handle an...
