The opening and closing part of manual butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating.
The butterfly plate of the manual butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc butterfly plate rotates around the axis, the rotation angle is between 0 and 90 and when the rotation angle is between 0 and 90 the valve is fully open. The butterfly valve is simple in structure, small in volume and light in weight, and consists of only a few parts. The valve can be switched on and off quickly only by rotating 90 degrees. The operation is simple and the valve has good fluid control characteristics.
The butterfly valve is a simple regulating valve, which is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body has a cylindrical shape with a short axial length and a built-in disc. The butterfly valve has the advantages of flexible operation and labor saving, and can be selected by manual, electric, pneumatic, hydraulic, and convenient installation, and is well received by everyone. I believe that many people don’t know much about the specifications and models of butterfly valves. Let’s take a look at the specifications and models of butterfly valves.
Butterfly valve advantages
It is convenient, quick, labor-saving, and has low fluid resistance. It can be operated frequently.
The butterfly valve model indicates that the sequence code is generally: butterfly valve type code, butterfly valve transmission mode, butterfly valve connection form, butterfly valve structure form, butterfly valve sealing surface material or lining material, butterfly valve nominal pressure, butterfly valve body material, which is the most basic arrangement mode D341X. -16C. The above is a brief introduction to the specification and model of the butterfly valve. It can be known from the above that the butterfly valve has a wide application range. The butterfly valve is widely used not only in general industries such as petroleum, gas, chemical, water treatment, but also for cooling of thermal power stations. water system. When installing the butterfly valve, you should pay attention to the valve flap to stop at the closed position. The opening position should be determined according to the rotation angle of the butterfly plate. The butterfly valve with the bypass valve should open the bypass valve before opening. I hope that the introduction of these butterfly valve specifications and models can help everyone.
