The basic principle of direct gas pressure regulator is what direct gas pressure regulator is a very important one in gas pressure regulator. It is important to consist of two parts: pilot and main valve. The function of this gas pressure regulator Very compact and very delicate to use, [What is the basic principle of direct gas pressure regulator?] Direct gas pressure regulator is a very important type in gas pressure regulator. It is important to have two pilots and main valves. Most of the components, this gas pressure regulator is very compact and has a very delicate use. What is the root of the direct gas pressure regulator?
In the process of organizing the launch, adjust the pilot to control the spring, so that the pilot valve port is open, P1 passes this valve port to save the pressure drop and becomes the load pressure P3. P3 acts on the large membrane, and the main spring is tightened through the ejector bullet. The main valve port is opened, and the output airflow acts on the large membrane and the pilot membrane to close the main valve port and the pilot valve port.
Adjust the pilot to control the spring, adjust the P2 to the set value. In this environment, the force of the P2 and the main spring on the large membrane and the force of the P3 effect are in equilibrium, and the P2 and the pilot control The force of the spring on the pilot film is also in equilibrium. The airflow flowing into the pilot by P1 is the same as the airflow flowing out of the pilot by the pilot. The pilot valve port and the main valve port must be open. P2 is very stable.
When the load increases and P2 decreases, the balance will be seriously damaged. The opening of the pilot valve port and the main valve port will become larger, the flow will become larger, and the P2 will rise to the set value. The gas pressure regulator will be in a balanced state again. At the moment when the pressure of the vulgar is rising, its pressure regulation process is reversed.
