Description

A saddle type combined connector

Technical Field

The utility model relates to the technical field of pipe fittings, and more specifically to a saddle-shaped combined connector.

Background technique

Tee fittings usually consist of a main pipe and two branch pipes to achieve the function of diversion or confluence in the pipeline system. Its structural design needs to consider the smoothness of fluid flow and the tightness of the connection. The material selection of tee fittings needs to be compatible with other pipes in the pipeline system and be able to withstand the pressure, temperature and medium requirements under working conditions. The manufacturing process of tee fittings usually includes forging, casting or welding, etc., and attention should be paid to process performance and manufacturing accuracy to ensure the quality and reliability of the connection. Since there is a certain area change between the branch pipe and the main pipe of the tee fitting, the resistance of the fluid will increase, causing energy loss. There may be a risk of leakage at the connection of the tee fitting, especially under high pressure or high temperature environment. In order to solve this problem, the sealing of the connection point can be increased, and sealing gaskets or other sealing materials can be used to ensure the reliability of the connection. Compared with other conventional pipeline connection devices, the manufacturing cost of tee fittings is higher. This is mainly due to its special structure and manufacturing requirements. When the tee fitting is loaded, it may cause uneven force distribution, especially at the connection between the branch pipe and the main pipe.

As the country pays more and more attention to the construction of high-standard farmland, agricultural water supply and drainage pipelines are widely used by farmers, and a lot of pipe fittings are also needed. At present, there are some common problems with the related pipe fittings on the market.
