High pressure flat gate valve

First, High pressure flat gate valve product brief

This series of products using a new balanced floating seal structure for pressure is not greater than 40MPa, the temperature is not higher than 120 ℃ water, oil, natural gas and other pipelines, as the control medium opening and closing device, the product design novel , The selection of appropriate, rigorous testing, light operation, with strong anti-corrosion, wear resistance, erosion resistance, the oil industry is an ideal new equipment.

Second, High pressure flat gate valve structure and working principle  
1, the use of floating seat, two-way opening and closing, sealed and reliable, flexible opening and closing.  
2, the lower part of the gate has a diversion hole, and to give precision guide, while the seal are sprayed carbide, erosion resistance.  
3, the valve body carrying capacity is high, the channel is straight-through, fully open, and the gate diversion hole through and straight tube similar flow resistance is very small. Stem with composite packing, multi-sealed, making the seal reliable, small friction.  
4, close the valve, turn the hand wheel clockwise, the gate down to the bottom, due to the role of medium pressure, the inlet side of the seal seat to push the direction of the gate. The formation of a larger seal than the pressure, thus forming the first seal. At the same time, the gate pressure to the outlet end of the seal seat, a double seal.  
5, due to the use of double seal, it can not affect the work of the pipeline more vulnerable parts. This is our product priority over similar products at home and abroad important features.  
6, open the gate, the counterclockwise rotation hand wheel, the gate shift, diversion hole and channel hole through. With the rise of the gate, through the hole gradually increased to the extreme position, the diversion hole and the channel hole coincidence, this time fully open.
