Characteristic:

Sanitary manual butterfly valve not only has the advantages of simple structure, small volume, light weight, low material consumption, small installation size, small driving torque, simple and rapid operation, but also has good flow regulation function and closing sealing characteristics.

Advantage:

1. The opening and closing parts of sanitary manual quick installation butterfly valve rotate about 90 ° to open,

close and regulate the fluid channel.

2. When it is fully opened, it has small flow resistance. When it is opened between about 15 ° and 70 ° it can also carry out sensitive flow control. Therefore, butterfly valve is widely used in the field of large diameter regulation;

3. The movement of the valve plate of the sanitary manual quick installation butterfly valve has wiping property, so the welding butterfly valve can be used for the medium with suspended fixed particles, and can also be used for the powdery

and granular medium according to the strength of the seal.

Product Description: butterfly valve is a kind of valve which uses round butterfly plate as the opening and closing part and rotates with the stem to open, close and adjust the fluid channel. The butterfly plate of butterfly valve is installed in the diameter direction of pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, with the rotation angle between 0 ° and 90 ° and when it rotates to 90 ° the valve is fully open.

FQA:

1.What kind of inspection does the valve have before delivery?

The material composition, internal and external leakage test pressure, appearance inspection, painting standard and pressure standard of the valve are the testing items.

2.What types of threaded connections are commonly used?

(1) Ordinary screw Bai pattern: the tooth shape is triangle, which is used to connect or fasten parts. Ordinary thread can be divided into coarse thread and fine thread according to pitch. Fine thread has higher connection strength.

(2) Transmission thread: the tooth shape is trapezoid, rectangle, saw and triangle. It can transmit axial power.

(3) Sealing thread: used for sealing connection, mainly pipe thread, taper thread and taper pipe thread.

3.What kind of inspection does the valve have before delivery?

The material composition, internal and external leakage test pressure, appearance inspection, painting standard and pressure

standard of the valve are the testing items.
