J44B flange Angle ammonia stop valve, flange Angle ammonia stop valve,stop valve

J44B Flange Angle ammonia globe valve Product introduction:

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.

Ammonia, ammonia liquid medium pipeline and liquefied gas pipeline for opening and closing function. Applicable media: liquid, gas, ammonia, nitrogen, hydrogen; Applicable temperature: -40℃-150℃ is mainly suitable for freezing, refrigeration, chemical industry, petroleum, food, smelting, liquefied gas and other units.

Product working principle:

The opening and closing part is a plug shaped valve disc, the sealing surface is plane or cone, and the valve disc moves in a straight line along the center line of the fluid. The movement of the valve stem has a lifting rod type (the valve stem is lifted, the handwheel is not lifted), and a lifting rotary rod type (the handwheel is rotated with the valve stem, and the nut is located on the valve body). The globe valve is only suitable for full opening and full closing, and is not allowed to be adjusted and throttled.

How it works:

one The high pressure chamber of the ammonia valve 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.

2. 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.

3. Ammonia stop valves are equipped with safety valves. It is a device to protect the ammonia gas 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.

J44B flange Angle ammonia globe valve design features:

1) The middle flange is a 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 sealed with the valve foot in line.

3) The sealing surface adopts babbitt alloy, good sealing performance and long service life
