Principle of self-acting pressure control valve
Automatically maintains the pressure before or after the valve at a certain value
It is still based on the principle of feedback control. A pressure tap is used to measure the pressure to be controlled (either before or after the valve), and this value is compared with the force applied by the setting spring; when they are equal, the valve is closed, while when there is a difference, the valve opens. The greater the imbalance in force, the greater the degree of opening.
Change stand to Force, and you’ll understand.
You don’t look up the principles in books or on the internet by yourself.
The opening degree of the valve is adjusted using the pressure of the medium itself, the force of the spring, and the weight of the valve core, without the need for any external force.
