Improvement of the hydraulic gate valve

Today, the gate valve gasification system applications in the small nitrogenous fertilizer industry is still more. The most widely used is undoubtedly the hair valve, nearly 70% of a single furnace systems are using a gate valve, a hydraulic butterfly valve is a valve into the furnace damper position. Connection is not linear gate valve in the duct valve installation corners and the hair resistance should not be generated. However, hair resistance to small? The original design of the gate valve there are two deficiencies First, the complex structure of the inner parts easy to fall off the high failure rate, high maintenance costs. The ram stroke, open the gate from 20% to 25% hanging at the valve port, not to mention up to produce resistance.air cylinder manufacturers
Improved methods:
(1) Improvement in the number of original design trim, cumbersome structure, connection and fastening methods unreasonable. Actual production due to hair gate valve the fault affecting production at the highest risk, a total of 12 pieces of the old gate valve: gate two, a spool, wedge one, up two iron coupling earrings parts, fastening bolts four, the structure is complex, demolition, installed very difficult.
The improved trim divided into six reduced by half. By the two bring their own child, mother claw clasp ram and a wedge, a wedge under composition. The four clever hook with each other, linked together as a set of. Open and close up, shrink flexible and reliable.
(2) the stem and wedge-way linking improvements, the original connection mode, the original design of the lower end of the stem of the T-shaped structure, with the upper end of the spool O-buckle slot hooked joins, the activities of the agency clearance to play, easy to fall off.pilot valves
