Valve industry is one of the important basic industries of the national economy. It not only provides people with light industrial valve products for daily use and medical use that are indispensable in daily life, but also provides various valve manufacturing equipment or valve parts for heavy industries and emerging industries such as mining, transportation, construction, machinery, electronics, etc.
It can be seen that the valve industry has a wide range of products, and the backward industry is very broad. According to the connection mode, it can be divided into three types: loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into single sphere, double sphere, curved sphere, etc. The tubular valve part is composed of inner and outer rubber, cord fabric and steel ring, which is formed by vulcanization and then loosely combined with metal flange or parallel joint. This product can reduce vibration and noise, and can compensate for thermal expansion and cold contraction caused by temperature changes. It is widely used in various pipeline systems.
