Large caliber soft sealed electric butterfly valve for water discharge

Large caliber soft sealed electric butterfly valve for water dischargeValves can be used to control air, water, steam, various corrosive media, mud, and oil productswaitThe flow of various types of fluids such as media. It mainly plays a role in cutting off and throttling on pipelines. The butterfly valve opening and closing component is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve the purpose of opening, closing, or adjusting.

Butterfly valves use disc type opening and closing components to rotate back and forth90°A valve that opens, closes, or adjusts the flow rate of a medium from left to right. Butterfly valves not only have a simple structure, small size, light weight, low material consumption, small installation size, low driving torque, easy operation, and fast speed, but also have good flow regulation function and closing sealing characteristics. They are one of the fastest developing valve varieties in the past decade. Butterfly valves are widely used. The variety and quantity of its use are still expanding, and it is developing towards high temperature, high pressure, large diameter, high sealing, long service life, excellent regulating characteristics, and multi-functional one valve. Its reliability and other performance indicators have reached a high level.

When the butterfly valve is opened, it has a small flow resistance. When opened at approximately15°~70°Butterfly valves are widely used in the field of large diameter regulation due to their ability to perform sensitive flow control during intervals.

Due to the wiping nature of the butterfly valve disc movement, most butterfly valves can be used for media with suspended solid particles. Depending on the strength of the seal, it can also be used for powder and granular media.

Butterfly valves are suitable for flow regulation. Due to the significant pressure loss of butterfly valves in pipelines, which is about three times that of gate valves, when selecting butterfly valves, the impact of pressure loss on the pipeline system should be fully considered, as well as the strength of the butterfly plate to withstand the pressure of the pipeline medium when closed. In addition, it is necessary to consider the limitations of the working temperature that the elastic valve seat material can withstand at high temperatures.

The structure length and overall height of butterfly valves are relatively small, with fast opening and closing speeds and good fluid control characteristics. The structural principle of butterfly valves is suitable for making large-diameter valves. When a butterfly valve is required for controlling flow, the most important thing is to choose the correct specifications and types of butterfly valves so that they can work properly and effectively.

Usually, in throttling, regulating control, and mud media, short structural length, fast opening and closing speed, and low pressure cutoff are required(Small pressure difference)We recommend using butterfly valves. Butterfly valves can be used for channels with dual position adjustment, reduced diameter, low noise, air pockets and vaporization, small leakage to the atmosphere, and abrasive media. Under special working conditions, throttling adjustment is required, or strict sealing, severe wear, and low temperature are required(cryogenic)Under the same working conditions.
