detailed description
Anti collision over coil valve fp-l6 anti collision over coil valve is a two position two-way handle control valve, which is equivalent to a gas circuit switch. The handle can automatically reset to the middle position. It is mainly used for oilfield workover rigs. Service status: when the traveling block hook is lifted to a certain height, the steel wire rope touches the anti-collision ring valve. At this time, the air inlet of the anti-collision ring valve is opened, and the air source enters the anti-collision ring valve through the anti-collision valve, and then enters the right chamber of the two position five way reversing valve, pushing the two position five way reversing valve to move to the left. At this time, the gas enters the cylinder through the two position five way reversing valve, and the cylinder pushes the brake booster to drive the brake handle and brake the drum, Prevent the traveling block hook from rising and touching the crown block.
Release: when the anti-collision valve is manually operated, the gas enters the left chamber of the two position five way reversing valve. The gas in the anti-collision coil valve is emptied through the two position five way reversing valve. The gas in the left chamber of the cylinder is emptied. Under the action of the spring, the cylinder is reset. At this time, the anti-collision crown block is released
