Ammonia shut-off valve is often used in oxygen, nitrogen, hydrogen, argon and other gases. This type of gas is usually stored in a dedicated high-pressure gas. During use, the ammonia gas passes a shut-off valve to reduce the gas pressure to the range required by the experiment, and then through the fine adjustment of other control valves, the gas from the gas stove solenoid valve manufacturer is input into the use system. The commonly used pressure reducing valve is a stop valve for ammonia, abbreviated as a valve for ammonia. The following is an explanation of the working principle of the shut-off valve for ammonia:
Working principle of ammonia shut-off valve:
The high-pressure chamber of the ammonia valve is connected to the steel cylinder, and the low-pressure chamber is the gas outlet, leading to the use system. The value of the pressure gauge is the pressure of the gas stored in the cylinder. The outlet pressure of the pressure gauge can be controlled by adjusting the screw.
During use, first turn on the main switch of the cylinder, and then turn the pressure adjustment screw of the low pressure gauge clockwise to open the valve by compressing the main spring and driving the membrane, spring pad and ejector rod. After the input high pressure gas is reduced by throttling, it enters the low pressure chamber through the high pressure chamber, and then enters the working system through the outlet. Rotate the adjusting screw to change the opening height of the valve, thereby adjusting the passing rate of high-pressure gas to reach the pressure value required by the pilot diaphragm solenoid valve.
The ammonia valve is equipped with a safety valve. The device can protect the ammonia pressure reducing valve and make it safe to use, and it is also a signal device for the failure of the ammonia pressure reducing valve. If the valve is damaged or due to
For other reasons, the outlet pressure automatically rises. When it exceeds a certain allowable value, the safety valve automatically opens to exhaust.
