How to adjust liquid pressure?
Thread Content
In the polysilicon industry, can the pressure of chlorosilane liquids be controlled using control valves? How can the pressure of liquid chlorosilane be reduced from 0.6 MPa to 0.2 MPa? As far as I remember, control valves can only adjust the flow rate or the pressure of gas
During the learning phase, just a few brief remarks for reference: it’s possible to change the diameter, or add a throttling mechanism; in essence, regulation is achieved by adjusting the flow rate, haha.
I’m not familiar with this liquid; its properties are unclear, so I’m just guessing. For a control valve, one that is used to regulate pressure should be chosen, with the pressure after the valve as the target. It’s simply a matter of adjusting it either up or down; what’s important is to select the right type of valve. In extreme cases, when the valve is fully closed, the pressure difference before and after the valve exceeds 4 bar (of course, this depends on the pressure at the end point)
