进口三偏心软密封蝶阀美国阿卡迪亚品牌

进口三偏心软密封蝶阀Product Description:

The upper sealing plate and the lower sealing ring of the butterfly shaft are integrally connected with the valve body, and the upper sealing plate and the lower sealing ring of the butterfly shaft are respectively connected with the valve body through the sealing plate of the butterfly shaft and the lower sealing ring, The sealing ring of the valve body is pressed on the valve body through the pressure ring, and an adjusting device for adjusting the sealing ring of the valve body is arranged on the body ring adjusting plate. Small friction coefficient and small on-off valve torque.

进口三偏心软密封蝶阀characteristic:

]The three eccentric hard sealing butterfly valve in the form of wire seal is metal elastic ring to metal rigid ring. Relying on the interference of the sealing pair, the metal elastic sealing ring is bonded with the metal rigid ring to produce elastic deformation, achieve the sealing specific pressure and realize sealing. Due to the need to ensure the axial bearing strength, the metal elastic ring needs a certain thickness, and the smaller the diameter, the stronger the radial rigidity of the metal elastic ring and the more difficult it is to deform, resulting in a large torque of the on-off valve.

进口三偏心软密封蝶阀Principle:

The three eccentric soft sealing butterfly valve comprises an upper valve shaft, a lower valve shaft, a pin, a butterfly plate, a valve body sealing ring, a pressure ring and a body ring adjusting plate of the valve body. The butterfly plate is connected with the upper valve shaft and the lower valve shaft through several pins and installed in the valve body. The butterfly plate is provided with a butterfly plate sealing ring integral with the butterfly plate. The sealing surface of the butterfly plate sealing ring adopts the form of surfacing. As shown in Figure 3, the sealing surface of the butterfly plate adopts a three eccentric structure, The body ring adjusting plate is connected to the valve body, and the sealing ring of the valve body is pressed on the valve body through the pressure ring, and the body ring adjusting plate is provided with an adjusting device for adjusting the sealing ring of the valve body.
