Product Parameters
★ GB flange ball valve structure features:
1, manual floating ball valve switch indication
The ball, stem and handle are the moving parts of the valve and are an assembly unit. The head of the stem adopts a flat square structure. It is easy to tell from the position of the handle whether the valve is in the open or closed position. When the handle or stem square is parallel to the pipe axis, the valve is in the open position; When the handle or stem square is perpendicular to the pipe axis, the valve is in the closed position.
2, national standard flange ball valve in order to prevent misoperation of the valve, Ruitong valve factory in the design of the ball valve with a lock-hole positioning plate to meet the user's process requirements, in the valve fully open or fully closed position can lock the valve.
3, national standard flanged ball valve stem anti-fly structure
When the medium passes through the valve, the pressure in the body cavity may push the stem out. To prevent this from happening, a boss structure is provided at the lower part of the stem. In this way, even if the fire, the packing, the thrust bearing is burned or other reasons caused by the packing damage, the medium pressure in the valve body will make the valve stem convex and the valve body seal close contact to prevent a large number of media from the damaged packing part of the leak.
4, national standard flange ball valve anti-static device
When the valve is operated, electrostatic charges are generated and accumulate in the ball line due to friction between the ball and non-metallic materials such as polytetrafluoroethylene. In order to prevent electrostatic sparks, the anti-static device is set on the valve, and the generated static electricity is exported (please contact the company's salesman for details).
5, national standard flanged ball valve fire structureRuitong Valve Co., Ltd. production of the national standard flange ball valve seat with a unique structure, when the fire, non-metal sealing surface material burned, the metal ring use the spring of the spring to push the seat and the ball seal, thereby preventing the spread of fire and media outflow. (Fire resistant structural design in accordance with API607, JB/T6899 and BS755)
6, the middle flange of the GB flange ball valve has no external leakage structure
The connection between the valve body and the left body is sealed by the cushion piece. In order to prevent the leakage of the seal caused by fire, high temperature or vibration, the valve body is specially designed to contact with the metal of the left body to form a stop flange to ensure that there is no leakage.
7, national standard flange ball valve automatic pressure relief structure
When the medium trapped in the valve cavity changes due to the pressure of the pipeline system or the temperature of the medium, resulting in an abnormal increase in the pressure of the cavity, the medium can rely on its own thrust to push the valve seat and automatically relieve pressure, thereby ensuring the safety of the valve.
