Figures 2-5 The upper end of the connecting pipe 310 is inserted into the positioning pipe 110, and the outer wall of the upper end of the connecting pipe 310 is in interference fit with the inner wall of the positioning pipe 110, and anaerobic glue is coated between the connecting pipe 310 and the positioning pipe 110.

[0035] The outer wall of the lower end of the connecting pipe 310 is adapted to the inner wall of the valve body 200, and a gap is reserved between the outer wall of the lower end of the connecting pipe 310 and the inner wall of the valve body 200; in some embodiments, the lower end of the connecting pipe 310 is inserted into the valve body 200, thereby realizing the connection between the connecting pipe 310 and the valve body 200, or the upper end of the connecting pipe 310 is inserted into the positioning pipe 110, and the lower end of the connecting pipe 310 is inserted into the valve body 200, thereby limiting the connecting pipe 310.

[0036] The valve body 200 is the shell of a conventional ball valve, and the connecting pipe 310 is used as the bonnet of the ball valve, thereby avoiding the connecting pipe 310 from falling off from the positioning pipe 110, and as another solution, the valve body 200 can be used as the mounting seat of the ball valve.

[0040] It should be noted that the collector body and the distributor body 100 are used together and are called a sub-collector, the structure of the collector body is the same as that of the distributor body 100, and the difference between the two is that the distributor body 100 is used to distribute heating water to the heating branch pipe, and the collector body is used to collect the backflow water of the heating branch pipe. It is only a name defined according to the different use positions; that is, the valve body 200 is also welded on the collector body, and the valve body 200 and the collector are also sealed by the sealing element 300; thus, the structure of the collector body will not be described again.

[0041] The working principle of the utility model is as follows:

[0042] After the valve body 200 is welded with the distributor body 100, the welding portion 400 serves as the first sealing between the valve body 200 and the distributor body 100, the upper end of the connecting pipe 310 and the positioning pipe 110 are coated with anaerobic glue, the upper end of the connecting pipe 310 is pressed into the positioning pipe 110, and the installation of the connecting pipe 310 is realized. At this time, the sealing ring one 321 seals the gap between the connecting pipe 310 and the positioning pipe 110, the sealing ring two 330 seals the gap between the connecting pipe 310 and the valve body 200, and the medium in the positioning pipe 110 and the valve body 200 cannot contact and corrode the inner side of the welding portion 400. In other words, the sealing element 300 serves as the second sealing between the distributor body 100 and the valve body 200, and the distributor body 100 has two layers of sealing. Even if the welding portion 400 is corroded due to the use environment, the welding portion 400 will not leak, and the sealing performance is more stable.

[0043] In addition, the groove one 311 limits the sealing ring one 321, the groove two 312 limits the sealing ring two 330, the connecting pipe 310, the sealing ring one 321, and the sealing ring two 330 are equivalent to an integral component, and the connecting pipe 310 can be directly installed in the positioning pipe 110 before or after welding, without affecting the normal welding of the valve body 200 and the distributor body 100, and is convenient to install and disassemble. Example two:

[0044] The difference between example two and example one is that: Figure 7As shown, the sealing part one 320 is an outer thread 322 arranged on the outer wall of the connecting pipe 310, and the positioning pipe 110 is internally provided with an inner thread 111 matched with the outer thread 322, after the outer thread 322 is connected with the inner thread 111, the gap of the positioning pipe 110 to the welding part 400 is sealed, and the outer thread 322 and the inner thread 111 are also coated with anaerobic adhesive, so as to further improve the air tightness between the outer thread 322 and the inner thread 111, and at the same time, the corrosion resistance of the outer thread 322 and the inner thread 111 can be improved.

[0045] The connecting pipe 310 is internally provided with a hexagonal through hole 313, by inserting a tool into the hexagonal through hole 313, the connecting pipe 310 can be easily rotated, so that the upper end of the connecting pipe 310 is screwed into or out of the inner thread 111, and the connecting pipe 310 and the positioning pipe 110 are assembled or disassembled.

[0046] As shown, Figure 8 As another scheme, the sealing ring two 330 is directly arranged at the connection between the water distributor main body 100 and the valve body 200, that is, the sealing ring two 330 is tightly arranged on the connecting pipe 310, the valve body 200 and the water distributor main body 100 at the same time, so as to seal the inner side of the welding part 400 from the inside of the valve body 200, and the welding part 400 will not be in contact with the medium in the water distributor main body 100.
