[0046] Preferably, the overall structure of the upper end cover 321 and the lower end cover 322 is an outer hexagonal shape and an inner circular shape, and the outer hexagonal shape facilitates the disassembly and assembly of the end covers;

[0047] It should be noted that the present invention is a hollow tubular structure with thin sides and thick middle, and the material is ductile iron, and the process is casting process.

The first boss 21, the second boss 22 and the upper end cover 321 and the lower end cover 322 adopt double sealing of thread sealing and O-ring. Thread sealant can be applied when thread sealing.

[0056] Corrosion resistance: integral electrophoresis is adopted, and since relatively large first bosses 21 and second bosses 22 are provided above and below, it can be ensured that no liquid is accumulated and the bottom is not exposed during electrophoresis.

[0057] Cleanliness: The main factor affecting cleanliness is the electrophoresis pre-treatment. The structure is a hollow tube, and the casting process is difficult. The surface roughness of traditional sand core casting is large, and it is also prone to casting defects. Therefore, this plan recommends the use of more advanced processes such as soluble cores, which can be cleaned during coring and ensure the roughness of the inner wall.
