Gate and butterfly valves are used to switch and regulate flow in pipelines. Of course, Shanghai Shanghai mega valve valve manufacturer in the butterfly valve supporting process is also a method and gate valve. According to the function and use of gate valve and butterfly valve, the flow resistance of gate valve is small and the sealing performance is good. Because the gate valve valve plate is perpendicular to the medium flow, if the gate valve is not switched in place, the medium on the valve plate will make the valve plate vibration, easy to damage the gate valve seal.

A butterfly valve, also known as the beat valve, is a simple structure of the regulator, that is, can be used to control the opening and closing of low pressure pipeline medium. Butterfly valve is a closing component flip or butterfly plate, it rotates around the valve shaft to achieve the valve opening and closing. Valves can be used to control the flow of air, water, steam, all kinds of corrosive media, mud, oil, liquid metal and radioactive media. The pipe mainly plays the role of cutting and throttling. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its axis in the valve body to achieve the purpose of opening and closing or adjusting. The disc is driven by the stem. If rotated 90 degrees, you can open and close once. The flow rate of the medium can be controlled by changing the deflection Angle of the disc.

The butterfly valve is used in the pipeline conveying corrosive and non-corrosive fluid medium in the kiln engineering system, such as gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting power generation, environmental protection, building water supply and drainage, etc. A series of valves for regulating and cutting off the flow of media. The gate valve is the gate plate of the opening and closing member. The direction of the motion of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be completely closed.

On-off, not suitable for the change of ram parameters, generally 5, medium temperature is not high 2° 52 '. In order to make up for the deviation of sealing surface Angle, the technology is improved. These gates are called elastic gates.
