Strong R & D and production of Germany valve hydraulic fan-shaped blind plate valve, also known as fluid dynamic fan-shaped glasses valve, mainly by the left body, right body, screw, ram, seals, levers, hydraulic cylinders and other parts, and by the base, the support columns to form a rigid structure. The valve has a clamp to release the cylinder and flap cylinder clamp, release the cylinder through the lever and screw screw driver left, the right body to complete release the clamping action, the flap cylinder drive gate to complete switch actions. The rubber ring insert clamp the gate, with a high temperature, sealing performance, the replacement of a convenient, long life characteristics. Hydraulic blind plate valve can be a single remote control can also be networked remote control, manual operation of the valve itself, the device can also be used under normal circumstances. 

 Structural characteristics of 
 1, fan-shaped structure, opening and closing valves for <90 ° of rotation, opening and closing rapidly since the operating flexibility. 2, the screw by force clamping structure, self-locking, sealing Vice does not automatically release the cause of media leaks. 3, an increase of water-cooling the valve, the maximum temperature ≤ 450 ° C, especially suitable for dry dust removal and cooling system. 4, with a variety of drive mode to choose from, pneumatic, hydraulic, electric computer program control. 5, the leakage rate: compliance of GB/T13927.

 Operating methods and precautions 
 1 Use a wrench to turn counter-clockwise rotating three connection screws, so that the separation of the body and the gate and have a balanced, the right amount of clearance (16mm). Rotation gate to confirm the working position, the reverse rotating connection screw, so that the gate and the valve body in close contact to achieve the purpose of absolutely sealed. 2, the rubber seals may not be the body of adhesion or the occurrence of hard friction to prevent damage to rubber seals, damage the valve performance. 3, fan-shaped blind plate valve open valve, around the valve body is released, the media want to leak out, to ensure safety, when it is closed, turn off the gas butterfly valve in the glasses in front of the valve, please use the draft and the other to ensure security measures, and recommended that the valve plate can not stand, just in case-made member of injury.
