Adjust the pneumatic valve, mainly in the line of control medium flow rate, pressure, temperature, etc. ;
Safety pneumatic valve, protects the piping or equipment, pressure relief effect.
What is the similarities and differences between the two?
Start with these two kinds of pneumatic valve working principle to get to know.
security pneumatic valve
in use process, the system pressure is too large, security pneumatic valve will jump. Pressure regulating pneumatic valve can be set pressure value, when the pressure is higher than this value, pneumatic valve opens, below this value, the pneumatic valve is closed. If we see it that way, adjust the pneumatic valve pneumatic valve can be used as a security. What is the difference in performance?
security pneumatic valve is used to protect piping or equipment. Pressure is very high, pressure is released. Voltage regulation is to maintain stability of the downstream pressure pneumatic valve, mainly in order to guarantee the stability of the downstream flow.
all in all, the security of pneumatic valve is to keep the pneumatic valve before the pressure stability, adjust pneumatic valve is used to maintain the pressure stability of pneumatic valves, of course, both are not interchangeable.
self-reliance type pressure regulating pneumatic valve
security work based on the system pressure pneumatic valve will automatically open and close. In general, the equipment installed in a closed system or pipe to ensure the safety of the system. When the pressure inside the equipment or pipeline exceeds safety pneumatic valve set pressure, automatic open pressure, to ensure the equipment and piping within the medium pressure in the set pressure, protection equipment and pipelines to prevent accidents. Adjust the pneumatic valve for regulating the flow of medium, pressure and liquid level. According to the adjusting part of the signal, the automatic control of pneumatic valve open, realize the adjustment of the medium flow rate, pressure, liquid level. In general, safety the pneumatic valve opens in the accident situation. After the opening, in theory the need for physical verification, and regulator is on, can adjust the flow or pressure in normal circumstances. Pneumatic valve -
security Set up a pressure point, a high pressure, and immediately jump.
pressure pneumatic - valve adjustment Set up a pressure point, the upstream pressure is higher than that of a, it maintain the downstream pressure is usually open!
security pneumatic valve is a kind of safety design for single equipment or pipe. When the pressure is too high, it will automatically jump to open, will work pressure returned to normal value. Protection at the same time, to prevent the equipment damage due to stress or accident. As the name implies, regulators play a regulatory role. It as a regulator to control the process parameters. The purpose of which is stable or adjusting control some certain temperature, pressure, flow rate or level in the upstream or downstream.
security pneumatic valve is commonly used in pressure vessel, belongs to the safety accessories. They must be strict inspection. If the security pneumatic valve can not adjust itself, must be adjusted for inspection.
