What is DIN3352 F4 resilient seated gate valve
DIN3352 F4 resilient seated gate valve adopts an integral flange-to-clamping device, and the sealing ring is made of hard alloy. The gate and sealing ring can be opened and closed without clearance. It has great shearing and cleaning functions. It is used for heavy media, and The bevel gear assists in cooperation to achieve a light opening and closing effect. Opening and closing of modern pipelines for mining, tailings, papermaking, sewage treatment, petroleum, food, etc.
The tooth shape of DIN3352 F4 resilient seated gate valve is arc-shaped, and is generally cone-shaped, resembling an umbrella shape, so it is also called bevel gear. Umbrella wheel has high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high carrying capacity, stable transmission, reliable work, compact structure, energy saving and material saving, space saving, wear resistance, long life and low noise.
DIN3352 F4 resilient seated gate valve is designed with screw drive and double-plane bearing, which greatly reduces the transmission friction and makes the valve opening lighter and smoother.
When the DIN3352 F4 resilient seated gate valve gate is in the closed position, the valve stem is pressed against the valve seat and the sealing ring by mechanical pressure. When the handwheel is rotated counterclockwise, the valve stem drives the gate to move upward, and the gate moves away from the seal. Ring, the valve stem continues to lift the gate (at the same time to restore the elastic fatigue state of the sealing ring).
When DIN3352 F4 resilient seated gate valve is turned off, turn the handwheel clockwise, the valve stem begins to fall, and the gate begins to fall. Continue to turn the handwheel. The valve stem pushes the gate down and pushes the gate to the closed position. When turning again, the gate has completely covered the passage at this time, and the gate is pushed to the closed position by the upper corner of the other side and the upper slide on the lower slope. At this time, the gate has completely covered the passage, and the gate is affected by the other side. The upper sliding block on the upper corner and the lower slope and the sliding block on the lower slope are pressed down on the ram, so that the ram continues to move downward when it is closed, so that the ram completely covers the upper part on the other side of the ram. When the sliding block and the lower sliding block are closed, turn the handwheel clockwise and the DIN3352 F4 resilient seated gate valve starts to move downwards.
