The cost of the flange gate valve is more expensive than ordinary valves, so when using valves, most manufacturers still use traditional valves, but in fact, the flange valve is not imagined under the overall use of the flange valve. The cost does not imagine the cost. It is so high. Many people think that the electric valve is expensive and the cost of use is high. In fact, if the overall calculation, the traditional valve must be added with many accessories and pipeline installation, the price does not dominate, but it must bear more maintenance costs. As far as the product itself is concerned, because the electric valve has easy assembly, low failure rate, and the advantages of the industry's automation needs, it is a cost -effective choice. Because the general traditional pneumatic valve is used, it is inevitable that there must be piping, solenoid valve, and compressor to achieve, and the electric valve is driven by a motor, which is easy to install and save. the costing payment. In addition, open and closer by motor -driven mode

When it comes to the flange gate valve, I believe that many people do not understand. In fact, the structure of the flank valve is relatively complicated, and sometimes it will encounter problems. The following editors will share the problems encountered by the special structure of the flange valve. I. The flanging valve due to the principle of the three eccentric structures. The seal between the cover of the valve board and the valve seat is to press the valve plate to the valve seat by the torque of the transmission device. When the state of the positive flow, the higher the medium pressure, the tighter the sealing. When the outflow of the runway is upside down, when the unit positive pressure between the valve board and the valve seat is less than the medium pressure, the seal begins to leak. Second, because the multi -layer software and hard stack sealing ring is fixed on the valve board, when the valve board is often opened, the medium forms a positive flush on its cover. After the soft seal band in the metal slice is washed up, the sealing performance directly affects the sealing performance. 3. Limit the structural conditions. This structure is not adapted to the valve below DN200, because the overall structure of the valve board
