Ammonia with ball valve

Product description

The product description

Ammonia ball valve in the valve body material selection of corrosion resistant steel (carbon steel added corrosion resistant alloy elements), can be resistant to gas, liquid ammonia corrosion, low temperature to -40℃- +120℃.

The valve body adopts precision casting to prevent the defects of poor corrosion resistance and easy perforation of the shell. Mainly suitable for refrigeration, refrigeration, chemical, petroleum, food, smelting, liquefied gas and other units.

Working principle of ammonia ball valve:

Ammonia ball valve and faran type ball valve is the same. The opening and closing part is a sphere, which rotates 90 degrees around the axis of the valve stem to realize the purpose of opening and closing. It is mainly composed of valve body, ball, valve seat, valve stem, handle and other components. Q41B ammonia ball valve adopts cast steel two-stage flange type, which is composed of right valve body and left valve body. The left valve body is flanged tube shape and the left valve body bowl surface match, the internal is equipped with a seat sealing ring, between them a ball is clamped, the ball has a through hole, the diameter of the through hole is equal to the inner diameter of the pipe.

Ammonia ball valve product features:

1. The valve has simple structure, reliable sealing and convenient maintenance. The sealing surface and the sphere are often in a closed state, which is not easy to be eroded by the medium and is easy to operate and maintain.

2, suitable for water, solvent, acid and natural gas and other general working medium, but also suitable for bad working conditions of the medium, such as oxygen, oxygen peroxide, methane and ethylene, etc., has been widely used in various industries.

3, easy to realize fast opening and closing, cut off, distribution and change the flow of media on the pipeline.

4. Compact structure, reasonable design, smooth channel patience, small flow resistance coefficient.

The product description

(1) According to the different requirements of use, ammonia pressure reducing valve has many specifications. The high inlet pressure is mostly, and the low inlet pressure is not less than 2.5 times of the outlet pressure. There are many outlet pressure specifications, generally, and high outlet pressure is.

(2) When installing ammonia ball valves, it should be determined whether the connection specifications are consistent with the joints of the use system. Ammonia ball valve adopts hemispherical connection, by screwing the nut to make the two completely match. Therefore, both hemispheres should be kept smooth when used to ensure good airtight effect. High pressure gas can be used to remove dust before installation. When necessary, materials such as ptfe can also be used as gaskets.

(3) Ammonia ball valves should strictly contact grease to avoid fire accidents.

(4) stop working, should be the rest of the air relief valve net, and then loosen the adjusting screw to avoid long-term compression deformation of the elastic element.

(5) Ammonia ball valve should avoid impact vibration, can not contact with corrosive substances.

The usage method and precautions of these ammonia valves are basically the same as those of ammonia valves. However, it should also be noted that dedicated ammonia valves are not generally used for other gases. In order to prevent misuse, some ammonia valves and cylinders between the use of a special connection. For example, ammonia and propane both use left thread, also known as reverse thread, special attention should be paid to installation.
