Electric gas butterfly valve is used in what fields, high temperature resistance

2018-07-06

Electric gas butterfly valve is a kind of gas butterfly valve, generally widely used in petroleum, gas, chemical industry, water treatment and other industries, but also used in thermal power station cooling water system, the main application of the document below 300 ℃, we can see how widely the use of this valve products! If the gas butterfly valve is required to be used as a flow control, the main thing is to correctly select the type and size of the valve. The structure principle of butterfly valve is especially suitable for making large diameter valve.

Electric gas butterfly valve opening and closing parts is a circular valve plate, which is suitable for use in a variety of pipe liquid material control, at the same time this valve has many types of size, we can choose a reasonable gas special valve according to the pipe size. Butterfly valve butterfly plate is oval, respectively connected at both ends of the valve plate, and then the valve will work when the valve plate will be connected to the center and then rotate, when the valve is fully opened with the maximum fluid throughput, this time the valve plate and the valve body frame presents a 90 degree angle.

The biggest feature of industrial electric gas butterfly valve can withstand high temperature, the valve plate sealing ring is used in the metal ring instead of the traditional rubber ring, so as to ensure the quality of the seal.

Gas butterfly valve has good fluid control characteristics. When it is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. It has elastic seal and metal seal two types of sealing. Elastic sealing valve, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate. Metal-sealed valves generally have a longer life than elastic-sealed valves, but it is difficult to seal completely. Metal seals can adapt to higher operating temperatures, and elastic seals have defects that are limited by temperature.
