Second, subject to structural constraints The structure is not adapted to the following diameter DN200 valves, because the overall structure of the valve plate is too thick, large flow resistance.
Third, due to the principle of triple eccentric structure, the seal between the sealing surface of the valve plate and the valve seat is to press the valve plate against the valve seat by the torque of the transmission device. In the normal flow state, the higher the medium pressure, the tighter the seal extrusion. When the medium of the flow passage is reversed, the seal begins to leak when the positive pressure between the valve plate and the valve seat is smaller than the pressure of the medium as the pressure of the medium increases.
ABS or PC Electroplating Production Line
The plastic plating production line is widely used in industries as car decorative parts, mobile phone decorative parts and logo signs. With the enlargement of the application of engineering plastics, plastic plating are expanding the using scope, mainly for the ABS, PC electroplating processing.
In the development process of automobiles and motorcycles pursuing lightweight and luxurious beauty, plastic electroplating has played a vital role. From door handles, car trademarks, nameplates, car interiors, reflectors, dial decorations to operating rod heads, steering wheel decorations, high-end wheel shell covers, grilles, decorative strips, etc., a large number of plastic electroplated products are used. Not only are automotive decorative parts, there are also a large number of plastic electroplated products on motorcycles and bicycles.
