The working principle of hydraulic control check butterfly pneumatic valve

hydraulic controlled check pneumatic valve is a butterfly, the swing arm heavy hammer structure, depend on the weight of the potential energy to close the pneumatic valve, but swing arm heavy hammer to take up the space is large, in the process of swinging a heavy hammer is likely to fall off, serious threat to the other equipment and personal safety. While maintaining a heavy hammer of potential energy need to keep certain pressure, hydraulic reversing pneumatic valve and hydraulic lock and the inevitable existence of leakage phenomenon, often need to pump the oil pressure to sustain heavy hammer potential energy tonic and pneumatic valve opening, so increased the operation cost, reduce the life span of the pump. According to the need, design the structure and mechanical lifting of heavy hammer hydraulic control check butterfly electromagnetic joint locking mechanism of pneumatic valve.
hydraulic controlled check butterfly pneumatic valve lift heavy hammer device by the framework, fan-shaped plate, block and tackle, hammer, steel wire rope and drives and other components of the oil cylinder ( Figure. Its feature lies in the sector plate center of rotation and swing arm with pneumatic cylinder's stem is connected, then there are fixed on the edge of the fan-shaped plate arc wire rope, wire rope at the other end of the bypass pulley block at the connection with a heavy hammer, all agencies are set up within the framework, structure is compact. When you start the pneumatic valve, device to send pneumatic hydraulic station of hydraulic pressure valve stem ( Drive the butterfly plate opening and heavy hammer ( Make the weight ascension produces potential energy. Close the pneumatic valve, will be a heavy hammer reverse potential energy transmitted to the pneumatic valve stem ( Drive disc closed.
mechanical joint electromagnetic locking mechanism is hydraulic control check adjustment of pneumatic valve, the spring return oil cylinder, wedge, set blocks, electromagnet and retractor. The device in the pneumatic valve to full open position, spring return oil cylinder feed movement, will limit block out of fan-shaped plate spacing, blocking electromagnet to absorb hook, hook on the wedge will limit block of the wedge on the hook, form the interlock. After its role is to improve the heavy hammer of potential energy locking, prevent heavy hammer to fall. Working principle of the

lift heavy hammer structure pneumatic valve opens, use the function of the oil supply lifting oil cylinder of the hydraulic pressure station, through the swing arm driven by pneumatic spare parts such as the stem drive disc to rotate counterclockwise °, achieve the goal of pneumatic valve opens. Lifting of heavy hammer structure at the same time, the action of oil cylinder force by fan-shaped plate, steel wire rope and pulley block parts will hammer vertical ascent to high, will be transformed into potential energy, the gravity of the heavy hammer to close the pneumatic valve is ready for the power. Pneumatic valve closing, first by electric control mechanical joint electromagnetic lock is unlocked, the weight of the potential energy through the wire rope and pulley block, fan-shaped plate and swing arm and the spare parts such as pneumatic valve rod drives the butterfly plate according to beforehand setting fast, go slow and slow close close program implementation.
pneumatic valve is fully open or lock when in place, spring return oil cylinder action, make the limit block extended to the lock position held fan-shaped plate spacing, formed at the beginning of mechanical lock lock. Then electromagnet to make electromagnetic force to overcome the spring force driving retractor action, hook hook set blocks on the wedge, form the electromagnetic lock. When close the pneumatic valves, solenoid, losing electricity retractor in under the action of spring force response, release to limit constraints, electromagnetic lock canceled, because of the limit block the constraints of the disappeared, spring return oil cylinder under the action of spring force impetus limit reply together, mechanical locking disappear, fan-shaped plate under the action of heavy hammer of potential energy to drive pneumatic valve stem and disc rotating together, pneumatic valve shut off. The potential energy by weight limit block mechanical lock, mechanical lock lifted by electromagnetic lock, electromagnetic lock to lift it is controlled by electromagnet electromagnetic force. As long as the electromagnet electricity, its electromagnetic lock will be brought under control and mechanical lock, ensure that the butterfly plate after open remain the state of full open ( Minimum flow resistance state, without any oil or fill pressure measures.
