Slab gate valve features
1. This series of products adopts a new type of floating sealing structure, which is suitable for oil, natural gas and other pipelines with a pressure of not more than 15.0MPa and a temperature of -29 to 121 °C. It is used as a control medium for opening and closing and adjusting devices. It has an appropriate material selection, strict testing, light operation, strong anti-corrosion, wear-resistance and erosion resistance. It is an ideal new equipment in the petroleum industry. Second, structural characteristics and working principle 1. It adopts floating valve seat, two-way opening and closing, reliable sealing and flexible opening and closing. 2. The gates are provided with guide strips for precise guiding, while the sealing surfaces are spray-welded with hard alloys and resistant to erosion. 3. The valve body has high bearing capacity, and the passage is straight-through. When fully open, it is similar to the straight pipe of the ram and the flow resistance is small. The valve stem adopts composite packing and multiple sealing, which makes the sealing reliable and the friction is small. 4. When closing the valve, turn the handwheel clockwise and move the ram down to the bottom. Due to the pressure of the medium, push the inlet end seal seat toward the ram direction to form a larger sealing pressure, thus forming the first seal. . At the same time, the shutter is pressed against the outlet end seal seat to form a double seal. 5. Due to the double seal, the consumables can be replaced without affecting the work of the pipeline. This is an important feature of our products in preference to similar products at home and abroad. 6. When the shutter is opened, the handwheel is rotated counterclockwise, the gate is moved, and the diversion hole is penetrated with the passage hole. As the gate rises, the through hole gradually increases. When the limit position is reached, the flow guiding hole and the channel hole coincide with each other, and are fully opened at this time.
