J11B ammonia stop valve with internal thread,ammonia stop valve with internal thread

J11B Internal thread ammonia globe Valve Product introduction:

The high pressure chamber is connected to the cylinder, and the low pressure chamber is the gas outlet and leads to the service system. The high pressure gauge indicates the pressure of the gas stored in the cylinder. The outlet pressure of the low pressure gauge can be controlled by the adjusting screw.

When in use, first open the cylinder main switch, and then clockwise turn the pressure adjusting screw of the low pressure gauge, so that it compresses the main spring and drives the film, spring pad and ejector rod to open the valve. The imported high pressure gas enters the low pressure chamber after throttling and decompression from the high pressure chamber, and leads to the working system through the outlet. Turn the adjusting screw to change the height of the valve opening, so as to adjust the passage of high pressure gas and achieve the required pressure value.

They are equipped with a safety valve, which is a device to protect the opening of the ammonia pressure reducing valve and make it safe to use, and is also a signal device for the failure of the ammonia gas pressure reducing valve. If the valve gasket, valve damage or due to other reasons, resulting in the outlet pressure to rise and exceed a certain allowable value, the safety valve will automatically open the exhaust.

Product working principle:

The sealing surface adopts babbitt alloy, tetrafluoroides, nylon, etc. Long service life. It is installed in the equipment or pipeline of the refrigeration system to connect and cut off the flow channel of the refrigerant, and can naturally achieve chemical treatment performance under the environment of temperature difference fluctuation during use.

It is suitable for opening and closing of ammonia, ammonia liquid medium pipelines and liquefied gas pipelines with temperature of -40~+150 degrees Celsius. It is mainly used in freezing, refrigeration, chemical industry, petroleum, food, smelting, liquefied gas and other units.

J11B internal thread ammonia globe valve design features:

one The middle flange is of square structure, and the valve stem is connected by an interbar.

2. The sealing surface of the valve body is shaped like a ball and is sealed in line with the valve foot.

3. The sealing surface adopts babbitt alloy, which has good sealing performance and long service life.

It is suitable for opening and closing of ammonia, ammonia liquid medium pipelines and liquefied gas pipelines with temperature of -40~+150 degrees Celsius. It is mainly used in freezing, refrigeration, chemical industry, petroleum, food, smelting, liquefied gas and other units.
