Valve on the body of what specific role, why adjust the two side of the second side of a static pressure?1, adjustable relief valve above the needle valve play what role? 2, when the first side pressure 7 kilograms, the two side sets 5 kilograms, why motionless for a while, the two side also rises to 7 kilograms? 3, adjustable pressure reducing valve can reduce static pressure? 4, the first side 6 kilograms, the two side set 5 kilograms, at this time there is water in the past, the past flow will not be affected by pressure? 5, it is said that when the pressure is adjusted, the first side is larger than the two side, 2 kilograms can be understood, right?
5., there is no such argument, look at the precision of the pressure reducing valve, if it is better, only 0.01 kg of pressure difference can also be used normally
3. for gas can, for liquid effect is not good
4., in the past, flow and pressure are related, in a certain pressure conditions can pass through the maximum flow, more than the flow will not work properly, the smaller the pressure difference, the maximum flow rate is smaller
1., the general valve needle is tapered, and its cooperation is a round hole, the valve needle up and down movement to adjust the size of the hole, thereby controlling the pressure2. there is no flow in theory, the valve is closed, but you can not completely shut down, so it will lead to two side pressure rise
