Introduction to d71x-6f handle wafer type plastic butterfly valve

Plastic butterfly valve has strong corrosion resistance, wide application range, wear resistance, easy disassembly, simple and easy maintenance, applicable fluids: water, air, oil, corrosive chemical liquids, and the valve body structure adopts the center line type. Classification of plastic butterfly valves: handle type plastic butterfly valve, worm type plastic butterfly valve, pneumatic plastic butterfly valve, electric plastic butterfly valve plastic butterfly valve is used in many fields. The product performance of electric plastic butterfly valve is summarized as follows:

1. The valve body of plastic butterfly valve only needs the minimum installation space, and its working principle is simple and reliable;

2. Approximate equal percentage flow characteristics, which can be used for regulation or on-off control;

3. The valve body of plastic butterfly valve is matched with standard convex pipe flange;

4. Superior economic performance makes the butterfly valve the most widely used in the industry;

5. Plastic butterfly valve has great circulation capacity, and the pressure loss through the valve is very small;

6. Plastic butterfly valve body has a very significant economy, especially for larger diameter butterfly valves;

7. Plastic butterfly valves are especially suitable for liquids and gases with cleaner media.

Plastic butterfly valves are connected to the pipeline system in the following ways:

Butt welding connection: the outer diameter of the valve connection part is equal to the outer diameter of the pipe, and the end face of the valve connection part is welded relative to the end face of the pipe;

Socket bonding connection: the connection part of the valve is in the form of socket, which is bonded with the pipe fittings;

Electrofusion socket connection: the connecting part of the valve is in the form of socket with electric heating wire laid on the inner diameter, which is electrofusion connected with the pipe;

Socket hot melt connection: the valve connection part is in the form of socket, which is connected with the pipe by hot melt socket;

Socket bonding connection: the valve connection part is in the form of socket, which is bonded and socket connected with the pipe;

Socket rubber seal ring connection: the connecting part of the valve is in the form of socket with rubber seal ring, which is connected with the pipe by socket;

Flange connection: the connecting part of the valve is in the form of flange, which is connected with the flange on the pipe;

Threaded connection: the connecting part of the valve is in the form of thread, which is connected with the thread on the pipe or pipe fitting;

Union connection: the connecting part of the valve is in the form of union, which is connected with pipes or pipe fittings.

A valve can have different connection modes at the same time.
