Although in some cases the flow can be changed by changing the pressure parameters, the self-acting pressure regulating valve can only regulate the pressure, and the flow of the device is not the function of the self-acting pressure regulator. There are two types of self-acting pressure regulators: front valve regulation and rear valve regulation. They can only regulate the pressure in front of and behind the valve. That is to say, regardless of what the rear valve is, the front valve type will not cause pressure fluctuations, and the valve remains unchanged. Stabilize the pressure in front of the valve; the valve type is only behind the valve, not in front of the valve.<\/p>\n\n\n\n
Self-actuating pressure regulating valve example analysis<\/p>\n\n\n\n
1. Self-regulating pressure control valve adjustment point<\/p>\n\n\n\n
1\u3001The flow Z of certain types of self-supporting valves is low. The valve fails to regulate when the valve quantity is less than a certain value.<\/p>\n\n\n\n
2\u3001The regulating mechanism includes some types of discrete command valves, which cannot be adjusted to death. (At this time, it can be seen that the valve stem does not change or does not change with the pressure fluctuation);<\/p>\n\n\n\n
3\u3001The control valve itself leaks too much. (At this time, the valve is usually in a fully closed position).<\/p>\n\n\n\n
What is the use of a self-actuated pressure regulating valve?<\/p>\n\n\n\n
2. Operation under steam conditions:<\/p>\n\n\n\n
1. Tighten the screws on the filler port.<\/p>\n\n\n\n
2\u3001Slowly open the front and rear shut-off valves of the control valve<\/p>\n\n\n\n
3. Adjust the pressure scale and observe the pressure to indicate that the value has reached the desired level.<\/p>\n\n\n\n
4\u3001Remove the screw from the service port of the condenser.<\/p>\n\n\n\n
5\u3001Loosen the actuator bleeder plug<\/p>\n\n\n\n
6\u3001Connect the pressure head to the oil fill port until the exhaust hole flows out.<\/p>\n\n\n\n
7\u3001Tighten the exhaust plug, continue to fill with water until the water overflows from the inlet.<\/p>\n\n\n\n
Three, operation at room temperature with gases or low viscosity liquids:<\/p>\n\n\n\n
1\u3001Slowly open the shut-off valve before and after the valve;<\/p>\n\n\n\n
2\u3001Loosen the exhaust plug until gas or liquid overflows from the actuator.<\/p>\n\n\n\n
3\u3001Then tighten the exhaust plug again and the regulator can work. The required pressure value can be obtained by adjusting the regulating plate. When adjusting, pay attention to the pressure indication value. Move slowly, and the valve stem should not rotate.<\/p>\n","protected":false},"excerpt":{"rendered":"
