Butterfly valve for transformer

Butterfly valve for power transformer is generally installed in the flange connection between oil immersed transformer and cooler, radiator, oil conservator and oil pipeline. It is used to open or close the oil circuit of transformer during vacuum oil filling and transformer operation and maintenance. It can also be used in accident or maintenance. The new type of fully sealed bevel contact is adopted, with fine processing and good sealing performance. The oil pressure at both sides is 0.5MPa and there is no leakage.

Spray painting, plastic spraying, hot dip galvanizing and electro galvanizing are adopted

Plate butterfly valve is a new generation of plate butterfly valve developed according to the characteristics of domestic and foreign products. It is the replacement product of cast iron plate butterfly valve in China. The valve body material is Q235 steel plate and stainless steel, which eliminates the leakage phenomenon caused by cast iron in the past. The fitting surface of valve body and valve plate is precisely processed by advanced CNC lathe, the leakage is very small, and the performance is better than the products in the same industry. Both ends of the butterfly valve are equipped with I-shaped seal ring, which is safe and reliable, and is equipped with special-shaped bolts. Among them, the plate butterfly valve with pipe has a section of connecting pipe that you need. Compared with the traditional butterfly valve, it reduces a leakage surface and saves a flange, which is economical and affordable.

The valve body of vacuum eccentric butterfly valve is made of Q235 steel plate and stainless steel plate, which eliminates the defects caused by casting and has no side leakage. The sealing ring on the butterfly plate adopts high-quality rubber and special technology to form a solid whole between the disc and the rubber ring, which solves the problem that the rubber ring is easy to fall off. This makes the sealing performance of butterfly valve better, no leakage. Among them, the vacuum connecting pipe butterfly valve can take a section of connecting pipe that you need. It reduces a leakage surface and saves a flange compared with the traditional butterfly valve. Both ends of the butterfly valve are equipped with I-shaped sealing ring, which is safe and reliable. The butterfly valve is equipped with special-shaped bolts.
