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

What are the uses of the flanges? Let's take a look with the French gate valve manufacturer! The opening and closing parts of the flange gate valve are the gate, and the movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be used as full and full levels, and cannot be regulated and throwing. There are two seals of the gate, and the two seals of the commonly used mode gate valve form wedge -shaped and wedge -shaped angles with valve parameters, usually 50, and 2 ° 52 'when the medium temperature is not high. The gate of the wedge valve can be made into a whole, called a rigid gate; it can also be made to produce a trace deformation gate to improve its processability and make up for the deviation of the seal angle during processing. This kind of gate is The board is called elastic gate. Pipeline flow, pressure, and temperature control of various industrial automated production. For example: power, metallurgy, petrochemical, environmental protection, energy management, fire protection system, etc. For a long time, the general gate valves used in the market generally have leakage or rust.
