Air pressure reducing valve

When the air pressure relief valve, YK43F compressed air pressure relief valve is out of the factory, the adjusting spring is in the uncompressed state, when the main valve and the valve are closed, the adjusting screw is rotated in clockwise direction, the adjusting spring is compressed, the diaphragm is moved to the top of the valve, the medium is entered above the piston by the a hole, and the piston is under the action of medium pressure. The lower movement drives the main valve to leave the main valve seat, so that the medium flows to the valve and the C hole enters the diaphragm at the same time. When the pressure exceeds the adjustment pressure, the diaphragm moves to the compression adjustment spring. The valve is moved to the closed direction, which reduces the medium above the piston and the pressure drops, and the main valve is in the main valve spring. When the force is pushed up and up, the gap between the main valve and the main valve seat decreases, the flow of the medium decreases and the pressure of the valve descends to the new balance. On the other hand, when the pressure of the valve is lower than the adjusting pressure, the gap between the main valve and the main valve seat increases and the flow of the medium increases to the new balance after the valve pressure increases. This product is mainly used in this product. Gas pipeline, such as gas, air, nitrogen, oxygen, hydrogen, liquefied petroleum gas, natural gas and other gases.
