(1) The Gate Valve adjusts the exhaust pressure and back pressure of the valve and must implement a Universal Valve opening test. Therefore, it is only possible after large-capacity testing equipment or the Relief Valve is installed in a protective device. Different valve adjustment methods.
The structure has a valve disc holder and a seat adjustment ring. The second is to adjust the valve seat ring. To loosen the adjustment ring screw from the exposed screw-like pin tool, you can drag the adjustment ring teeth to turn the adjustment ring left or right.
(2) When the adjustment ring moves counterclockwise to the left and reaches a high position, the pressure will be reduced and returned. On the contrary, when the adjustment ring is rotated clockwise, the exhaust pressure decreases to the right position and the back pressure must increase. Every adjustment, adjustment: the rotation range should not be too large.
The rear adjustment screw should be opened so that the adjustment ring groove between the two teeth can prevent the adjustment ring from rotating without radial pressure at the end of the adjustment. For safety reasons, before touching the adjustment ring, the opening pressure of the intake pressure Gate Valve should be appropriately reduced to prevent the adjustment valve from suddenly opening and causing an accident.
(3) The structure and adjustment of the upper and lower rings of the Gate Valve are relatively complicated. The adjustment ring that sits on the CD channel adjusts the size of the ring when the ring size changes, opening the disc chamber to an early degree of pressure accumulation. When adjusting the elevated seat of the ring, increasing levels of pressure build-up reduce the opening phase of the proportional valve, reaching sudden severe opening very quickly.
Therefore, adding a seat adjustment ring can reduce the outlet pressure. It should be noted that the seat adjustment ring should not be increased too close to CD. Therefore, seal leakage may cause the valve to suddenly open prematurely, but because the pressure of the media is not enough to set the Universal Valve in the open position and immediately close the Universal Valve, the seat is mainly used to reduce the Universal Valve adjustment: round, open stage and adjust the pressure, but There are also effects of pressure to repay.
Changing the provision of the CD at the bottom of the mobile media link reflects the turning point, and converts the force size to adjust the back pressure. As the adjustment ring rises, it reduces the flow intensity and therefore the backflow pressure. On the contrary, when the adjustment ring is lower, the back pressure decreases. The adjustment ring, of course, changes the return pressure, and at the same time, it will also affect the exhaust pressure, that is to say, the pressure of the adjustment ring rises and reduces the exhaust pressure to a very low level, but its effect is not obvious compared to the return pressure adjustment ring.
