Imported liquefied gas shut-off valve-American Buhrer brandAs a control medium cut-off opening and closing device. Product use: This globe valve uses elastic V-shaped polytetrafluoroethylene or DQ rubber as the dynamic sealing packing, and is initially sealed by a packing cover/stainless steel spring. The sealing performance of the packing is enhanced with the increase of medium pressure, that is, it has self sealing performance and does not require manual maintenance. Different from other valves, it is suitable for most high and medium pressure gas transmission pipelines, mixing stations, storage and distribution stations, and other occasions.
Imported liquefied gas shut-off valvePrinciple and structure:
1. When the handwheel rotates clockwise, the valve stem moves downward and the valve disc descends to seal the sealing surface, cutting off the passage When reversed, it opens and the valve stem is raised to the highest point for sealing.
2. This valve has added an upper seal When the valve is in the open state, it has a two-layer sealing effect together with the packing and has a certain protective effect on the packing.
3. This valve uses nylon products as the sealing surface, and the packing is soft formed packing. The upper seal is also made of soft material, and the sealing performance is good.
