Gapless Wafer Type Knife Gate Valve

Product Introduction

Gapless clamping knife gate valve is mainly assembled by the valve body, gate, screw rod, drive device, rubber ring, etc. When the valve is opened, the valve channel is lined with two high wear-resistant rubber ring, due to the unique expansion force of rubber and the front and rear flange sealing pressure difference, so that the valve sealing surface is closely combined to form a whole channel, no accumulation of sediment in the valve body when the fluid passes. When the valve is closed, using the elasticity of the rubber ring, the valve plate is inserted between the two rubber rings to cut off the fluid and increase the compression of the valve so that the sealing force between the gate and the rubber ring increases, that is, to maintain the seal of the gate and does not affect the opening and closing of the gate. Compared with the ordinary knife gate valve has more wear-resistant, will not be blocked by particles and other advantages, plus wear-resistant rubber ring can be replaced individually to a greater extent to improve the use cycle, as long as proper maintenance can be achieved "unlimited use".

Gapless clamping knife gate valve is widely used in the surrounding environment is relatively harsh, the valve cut off the medium for a variety of slurry, solid particles containing fluid and corrosive materials. Among them, air control, electric control more convenient to achieve the long-distance operation, reduce and avoid the way of contamination of the operator, and rapid switching, to achieve the automation of system operation provides convenient conditions.
