Valve material and connection

The valve is a control component in the fluid delivery system and has functions such as cut-off, regulation, diversion, reverse flow, pressure regulation, diversion, or pressure relief. Valves used in fluid control systems, ranging from the simplest shut-off valves to various valves used in highly sophisticated automatic control systems, are quite diverse in variety and size. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. Valve and pipe connection is an important parameter. According to this classification:

1. Threaded connection: The valve body has internal thread or external thread and is connected with the thread of the pipeline.

2. Flange connection: The valve body has a flange and is connected with the pipe flange.

3. Welding connection: The valve body has a welding groove and is welded to the pipe.

4. Clamp connection: The valve body has a clamp and is connected to the pipe clamp.

5, card sleeve connection: the use of card sleeve connection with the pipeline.

6, clip connection: the bolt directly to the valve and the two ends of the pipe through the connection form.

Valve body material:

1, metal materials: valve body and other parts made of metal materials. Such as cast iron, carbon steel, alloy steel, copper alloy, aluminum alloy, lead alloy, titanium alloy, Monel alloy and so on.

2, non-metallic materials: valve body and other parts made of non-metallic materials. Such as plastics, ceramics, enamels, glass and steel.

3, metal lining: The body shape of the valve is metal, and all the main surfaces in contact with the medium are linings, such as lining rubber, lining plastic, and lining ceramic.
