In a word, pneumatic butterfly valve is a kind of pneumatic valve commonly used at present. It has a high frequency of use in industries such as industrial, chemical and metallurgical industries. There are many types of pneumatic butterfly valves, and the most appropriate valve type can be selected according to actual needs.

Factors leading to damage of high-pressure hose
High pressure hose has been widely used in all walks of life, but sometimes it is found that the high-pressure hose is damaged. Next, we will analyze the cause of high-pressure hose fracture and better use. Quality cause: uneven hose wall thickness, poor quality; The steel wire is too tight, too loose, or the steel layer is too little
The rubber tube is deformed greatly, and the outer layer is poorly sealed, leading to steel wire corrosion; The inner layer is poorly sealed, high pressure oil is easy to enter the steel layer, and the bonding force between the bonding layer and the steel wire is insufficient, which reduces the bearing capacity of the hose, and finally leads to the bursting of the thin part of the pipe wall; During the assembly process of rubber hose and joint, the number of buckles and speed of buckles of rubber hose are not appropriate, which leads to premature failure of rubber hose in the application process
In addition, improper connector design and poor processing quality will cause damage to the inner rubber. If the connector information is improperly selected, it is easy to deform during the buckle process, thus affecting the buckle quality and shortening the hose life
Improper use: frequent and severe pressure shocks, high-pressure hose bursts, and oil temperature is too high. When construction machinery is working, the hydraulic system heats up the oil due to power loss. The higher the oil temperature, the easier the rubber aging, the lower the strength and sealing performance, hose bursts, and the rubber hose selection device is unreasonable, and the high-pressure rubber hose breaks from time to time due to friction
