Product description of Wafer Type Ball Valve
The valve plate of wafer ball valve and flange gate valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the valve body, the disc-shaped valve plate rotates around the axis, and the rotation angle is between 0 ° -90 °. When it rotates to 90 °, the valve is fully open. This valve is generally installed horizontally. Wafer ball valve and wafer butterfly valve are simple in structure, small in size and light in weight, and only consist of a few parts. Moreover, it can be opened and closed quickly by rotating 90 °, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the ball valve is in the fully open position, the thickness of the valve plate is the resistance of the medium flowing through the valve body, so the pressure drop generated by passing through the valve is very small, so it has good flow control characteristics. Tower 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 valve plate. Valves with metal seals generally have a longer service life than those with elastic seals, but it is difficult to achieve complete sealing. Metal seal can adapt to higher working temperature, while elastic seal has the defect of being limited by temperature. If the ball valve is required to be used as flow control, the main thing is to correctly select the size and type of the valve. The structural principle of ball valve is especially suitable for making large-diameter valves. Ball 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 stations.
Features of Wafer Type Ball Valve
① The unique eccentric design enables friction free transmission between sealing surfaces, extending the service life of the valve.
② The elastic seal is produced by torque.
③ The ingenious wedge-shaped design enables the valve to have the automatic sealing function of closing tighter and tighter, and there is compensation and zero leakage between the sealing surfaces.
④ Small size, light weight, light operation, easy installation.
⑤ Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.
⑥ The material of the replacement parts can be applied to various media and can be lined for corrosion prevention
Industrial applications of Wafer Type Ball Valve
It is used in the gas pipeline in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the electric demist series and connecting valve, the inlet and outlet of the S02 main blower, the converter regulation, the inlet and outlet of the preheater and other adjustments and the use of cut-off gas volume.
The sulfur burning, conversion and dry absorption sections used in the sulfur based sulfuric acid system are the preferred brands of valves for sulfur based sulfuric acid plants. They are considered by the majority of users as butterfly valves with good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient, flexible operation, safe and reliable use, which have been widely promoted and used.
It is also widely used as a regulating and intercepting device on the pipelines of SO2, steam, air, gas, ammonia, CO2 gas, oil products, water, salt water, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media in chemical, petrochemical, smelting, pharmaceutical, food and other industries.
