valves are connected in a variety of ways

As an indispensable control element in fluid piping systems, valves are connected in a variety of ways:

1. Flange connection

Valves are connected to pipes by matching flanges and bolted fasteners for high temperature, high pressure and large diameter piping systems.

2. Threaded connection

The use of internal and external threads to close the valve and the pipeline, mainly suitable for small diameter, low pressure pipeline system.

3. Weld the connection

The valve is welded directly to the pipe through the welding process, which is suitable for scenarios requiring high sealing and permanent connection.

4. Socket connection

One end of the valve is a socket, the other end is a jack, by inserting and sealing to connect, often used in plastic piping systems.

5. Clamp connection: there are clamping devices on both sides of the valve, and the valve is fixed on the pipeline through the clamping device, which is suitable for quick installation and disassembly.

6. Bushing connection: bushing connection is usually used for plastic pipe system, through the special bushing tool and bushing to achieve the connection of pipe and valve. This connection method has the characteristics of simple installation and convenient disassembly.

7. Bond connection

Adhesive connection is mainly used in some non-metal pipe systems, such as PVC, PE and other pipes. The pipe is bonded to the valve by using a special adhesive to form a permanent connection.

8. Clamp connection

Commonly known as trench connection, this is a quick connection method that requires only two bolts and is suitable for low-pressure valves that are often removed. The connection pipe fittings include two categories of products: (1) The pipe fittings that play the role of connection sealing have rigid joints, flexible joints, mechanical tees and grooved flanges; The pipe fittings that play the role of connecting the transition are elbows, three-way, four-way, reducing pipes, blind plates, etc
