At the same time, the pipe 2 is heightened from four directions by four bolts 4, which can also ensure its stability. The thermal insulation layer 34 filled inside the mounting ring 3 is specifically made of an aluminum silicate wool material. Aluminum silicate wool is an inorganic material that is non-flammable and corrosion-resistant, and has good thermal insulation effect and certain sound insulation effect. By filling the thermal insulation layer 34 inside the mounting ring 3, the thermal insulation performance of the fluid can be effectively improved to prevent the fluid from freezing due to excessively low temperature. At the same time, it can also reduce the impact of flow noise on the outside to a certain extent.

At this time, the pipe 2 is inserted into the inside of the valve pipe 11, and the first threaded hole 113 on the bottom surface of the mounting groove 111 coincides with the position of the second threaded hole 32 on the upper surface of the limit block 31. Then, the bolt 4 can be threaded through the first threaded hole 113 and threadedly inserted into The inside of the second threaded hole 32 can quickly and conveniently complete the installation and fixation between the pipeline 2 and the valve tube 11. After the installation is completed, the sealing ring 33 is close to the front end of the valve tube 11, which can further ensure the sealing of the connection between the valve tube 11 and the pipeline 2. By filling the thermal insulation layer 34 in the mounting ring 3, the thermal insulation layer 34 is specifically made of an aluminum silicate wool material.
