Butterfly Valve Features Fine Number

     What are the problems with the use of butterfly valves? One, because the multi-layer soft and hard laminated seal ring is fixed on the valve board, when the valve plate is open, the medium has a positive scour to its sealing surface, and the soft sealing belt in the metal interlayer has been washed, which directly affects the sealing performance. II. Restricted by structural conditions the structure is not suitable for DN200 the following valves because the overall structure of the valve plate is too thick and the flow resistance is large. Third, because of the principle of butterfly valve, valve plate sealing surface and valve seat between the seal is driven by the torque of the valve plate pressure to the seat. In the positive current state, the pipe clamp valve, the lining fluorine valve, the exhaust valve medium pressure higher seal squeeze tightens. The seal begins to leak as the dielectric pressure increases when the flow medium is upstream and the unit positive pressure between the valve plate and the valve seat is less than the medium. Four, high-performance lined fluorine butterfly valve, which is characterized in that: the valve seat sealing ring by the soft T-shaped sealing ring on both sides of multi-layer stainless steel sheet composition.Butterfly Valve
    The sealing surface of the valve plate and the seat is oblique cone structure, and the temperature and corrosion resistant alloy material is surfacing on the inclined cone surface of the valve plate, and the structure of the spring and the adjusting bolt assembly on the pressing plate is fixed on the adjusting ring plate. This structure effectively compensates the tolerance zone between the sleeve and the valve body and the elastic deformation of the stem under the medium pressure, which solves the sealing problem in the process of the two-way interchange medium conveying. The use of soft T-type multi-layer stainless steel sheet to form a sealing ring, with metal hard seal and soft seal of the dual advantages, both at low temperature and high temperature conditions, have 0 leakage sealing performance. The test results show that the pressure of the sealing surface is caused by the torque of the transmission device and the effect of the medium pressure on the valve plate when the Chisheng state (the flow direction of the medium is the same as that of the butterfly plate). When the positive medium pressure increases, the sealing surface of the valve plate is squeezed more tightly and the sealing effect is better.Butterfly Valve
    When upstream, the seal between the valve plate and the valve seat is driven by the torque of the driving device to pressure the valve plate toward the seat. With the increase of the reverse medium pressure, the unit pressure between the valve plate and the seat is less than the medium pressure, the spring of the colloid grinder filter regulating ring can compensate the tight pressure of the valve plate and the seat sealing surface by the deformation energy stored after loading. Therefore, the utility model does not install a soft and hard multi-layer sealing ring on the valve plate, but is directly mounted on the valve body, and the additional regulating ring in the middle of the platen and the valve seat is an ideal two-way hard sealing method.Butterfly Valve
