Innovative pneumatic lug butterfly valve, domestic high-quality product The pneumatic fluorine lined butterfly valve and anti-corrosion fluorine lined butterfly valve adopt the combination of two halves of valve body, and the valve seat and valve body lining are integrated. When the valve is working, only the full plastic valve seat and the plastic lined butterfly plate are in contact with the medium, and the product can withstand the corrosion of any medium except molten alkali metal and element fluorine. Among them, D71F46 valve rod and butterfly plate (forged) are integrated, and the surface is evenly coated with a layer of FEP. The inner surface of the valve body channel is smooth, the fluid resistance is small, the CV value is high, the flow capacity is strong, and the torque is moderate. The four stage sealing structure is adopted, and the temperature resistant and anti-aging SI rubber elastic gasket valve seat is equipped outside the sealing surface, completely achieving zero leakage of the medium.
The information of non-metallic compensator determines its use
The non-metallic contraction joint can compensate the axial, transverse and angular directions, has no thrust, simplified support design, corrosion resistance, high temperature resistance, noise elimination and vibration reduction, and is especially suitable for hot air pipes and soot pipes.
Main data used for non-metallic contraction joints:
Fluorocarbon tape is made of high-quality tetrafluoroethylene, glass fiber cloth, stainless steel wire mesh and other thermal composite materials. It has strong sealing property and can be used under the pressure of 700KPa. The long-term operating temperature is 250 ℃, and the short-term operating temperature can reach 300 ℃.
Tetrafluoro film sealing layer, high temperature resistance and corrosion resistance.
Teflon sealing layer, high temperature resistance, corrosion resistance, good flexibility.
Silicone tape is made of alkali free glass fiber cloth, silicone rubber, stainless steel wire mesh and other thermal composite materials. It has strong sealing ability, pressure bearing ability, high operating temperature, long-term temperature can be used below 200 ℃, operating pressure is 300KPa, short-term 16 hours can accept 250 ℃, and has good temperature resistance. Silicone tape cannot be used in places containing sulfur dioxide smoke and water vapor.
The non-metallic shrink joint literally means that the main body material is composed of fabric or other non-metallic materials.
