1. The opening and closing direction of the resilient seat seal gate valve shall be closed clockwise.
2. Because the pneumatic valve in the pipe network is often opened and closed manually, the number of opening and closing revolutions should not be too much, even the large-diameter valve should also be within 200-600 revolutions.
3. In order to facilitate the opening and closing operation of one person, the maximum opening and closing torque should be 240N-m under the condition of pipe pressure.
4. The opening and closing operating end of the resilient seat seal gate valve shall be square tenon, with standardized size and facing the ground, so that people can operate directly from the ground. Valves with discs are not suitable for underground pipe networks.
5. Display panel for opening and closing degree of resilient seat seal gate valve
① The scale line of the opening and closing degree of the resilient seat sealing gate valve shall be cast on the gearbox cover or the shell of the display panel after the direction change, all of which shall face the ground, and the scale line shall be painted with fluorescent powder to show eye-catching;
② The material of indicator dial needle can be made of stainless steel plate under good management, otherwise it is painted steel plate, and aluminum sheet is not allowed to be used;
③ The indicator dial needle is eye-catching and firmly fixed. Once the opening and closing adjustment is accurate, it should be locked with rivets.
6. If the resilient seat seal gate valve is buried deep and the distance between the operating mechanism and the display panel from the ground is ≥ 1.5m, an extension rod facility shall be provided and fixed firmly so that people can observe and operate from the ground. In other words, the valve opening and closing operation in the pipe network is not suitable for downhole operation.
