一、 Main overview of j44b ammonia angle stop valve:

The sealing surface of j44b ammonia angle stop valve adopts Babbitt alloy, tetrafluoroethylene, nylon, etc. Long service life. It is installed on the equipment or pipeline of the refrigeration system to connect and cut off the flow channel of the refrigerant. In the process of use, it can naturally achieve the chemical treatment performance in the environment of temperature difference changes. It is suitable for the opening and closing of ammonia and ammonia liquid medium pipelines and liquefied gas pipelines with a temperature of -40~+150 ℃. It is mainly applicable to freezing, refrigeration, chemical industry, petroleum, food, smelting, liquefied gas and other units.

二、 J44b ammonia angle stop valve product features:

1. The through flange is of square structure, and the valve rod is connected by an intermediate rod.

2. The sealing face of the valve body adopts a convex ball shape, which is sealed in line with the valve foot.

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

三、 Working principle of j44b ammonia angle stop valve:

The opening and closing part of j44b ammonia angle stop valve is a plug-shaped disc, the sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid. The movement form of the valve rod includes lifting rod type (the valve rod is lifted and the handwheel is not lifted), and lifting rotating rod type (the handwheel rotates and lifts with the valve rod, and the nut is set on the valve body). The stop valve is only applicable to full open and full close, and adjustment and throttling are not allowed.
