Stainless steel internal wire butterfly valve

Stainless steel internal wire butterfly valve

Produced by Shanghai Hesheng Valve Manufacturing Co., LtdStainless steel internal wire butterfly valveThe butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis at an angle between 0 ° and 90 °. When it rotates to 90 °, the valve is fully open. Specially designed for industrial fields such as dairy products, food, pharmaceuticals, beer, cosmetics, etc The pipe fittings and the parts in contact with the medium are all mirror polished. The sealing ring of butterfly valve with a diameter of Ø 63.5- Ø 108 can be used in two types: ethylene propylene diene monomer (EPDM) and silicone (SI). Valves with a diameter of Ø 57 or less are EPDM stainless steel manual quick installation butterfly valves. The opening and closing parts of the butterfly valve can be rotated back and forth by about 90 ° to open, close, and regulate the fluid channel. Stainless steel manual quick release butterfly valve not only has a simple structure, small volume, light weight, and low material consumption, but also has a small installation size and small driving torque, making it easy and fast to operate. It can also have good flow regulation function and closing sealing characteristics at the same time. Stainless steel manual quick release butterfly valves have low flow resistance when opened, and can perform sensitive flow control when opened between approximately 15 ° and 70 °. Therefore, butterfly valves are widely used in the field of large-diameter regulation; The movement of the stainless steel manual quick installation butterfly valve plate is wiping, so this welded butterfly valve can be used for media with suspended fixed particles, and can also be used for powder and granular media depending on the strength of the seal

Stainless steel manual quick installation butterfly valve belongs to the medium seal butterfly valve. Its sealing principle is to ensure that the sealing surface of the valve plate has a suitable surface roughness value during processing,synthetic rubberThe valve seat iscompression moldingForm a suitable surface roughness value for the sealing surface. When the valve is closed, the outer sealing surface of the valve plate presses against the synthetic rubber valve seat through the rotation of the valve plate, causing the synthetic rubber valve seat to produce elastic deformation and elastic force as the sealing pressure to ensure the sealing of the valve.
