The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc shaped butterfly plate rotates around the axis with a rotation angle of 0 �°~90 �°. When the rotation angle reaches 90 �°, the valve is fully open.
The butterfly valve is simple in structure, small in volume and light in weight, and only consists of a few parts. Moreover, the valve can be quickly opened and closed only by rotating 90 �°, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate.
The valve with metal seal is generally longer than the valve with elastic seal, but it is difficult to achieve complete sealing. The metal seal can adapt to higher working temperature, while the elastic seal has the defect of being limited by temperature.
If the butterfly valve is required to be used for flow control, the main thing is to correctly select the size and type of the valve. The structure principle of butterfly valve is especially suitable for making large diameter valves. Butterfly valves are not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power plants.
There are two kinds of butterfly valves commonly used: wafer type butterfly valve and flange type butterfly valve. Wafer type butterfly valve uses stud bolts to connect the valve between two pipe flanges. Flange type butterfly valve has flanges on the valve, and bolts are used to connect the flanges on both ends of the valve to the pipe flanges.
1. Product Introduction
Electric ball valve compare with the same sized gate valve and globe valve, it can all-closed and all-open when it rotate 90 degree. Valve channels diameter is equal with connection pipes diameter, so the medium can flow past without any leakage. Ball valve is a very important kind of valve, and widely used in the field of petrochemical industry and long-distance transport pipes. Its closure member is a part of globe with hole, and rotate along with valve rod to achieve open and close of valve.
2. Performance Feature
1. Apply to the occasion need two-position cut off and regulating.
2. Electric ball valve can achieve the medium cut-off and circulation functions in the transport pipeline of the petroleum industry, chemical industry paper making, metallurgy, sewage treatment and oil tank truck these fields.
3. High sealing performance and flow capacity, easy to assemble and maintain, small flow resistance, reliable seal.
4. Electric valve has the advantage such as small volume, light weight, large thrust, strong function, easy to operating, high reliability, and installed servo amplifier.
5. Can flow to any position, has wide adjustable range, and it can used for high pressure and big diameter occasion and to control the medium with high viscosity, fiber and fine particle.
6. Directly mounted type, with servo amplifier installed inside. Controlling and operating by output and input 4-20mA signal and 3800VAC voltage. It has the advantage such as easy to link, compact structure, stable and reliable operation.
Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
