вафли клапан-бабочка

wafer Butterfly Valve Three eccentricity metal butterfly valve seal is the introduction of the German MAK company to develop a new generation of technology products butterfly. Product performance have been ashamed at the leading domestic level, widely used in metallurgy, petroleum, chemical, electricity, municipal construction and other industries to make cut-off channels or adjust the volume with medium. The product mainly has the following characteristics: 1, short size, small size, light weight, portable operation. 2, the use of axle structure, butterfly plate for the truss structure, butterfly plate high strength, large area off the flow, small flow resistance, energy saving. 3, the unique design of the eccentric angle: the butterfly valve in the traditional structure of the double eccentric configuration based on the unique design of the eccentric angle, make full use of the cam effect, in order to achieve the valve open, the valve seat and seals from the transient, in 90-degree tour completely eliminate the friction and wear. 4, flexible metal to metal seal: welding butterfly valve seat surface temperature, corrosion resistant alloy materials, T-shaped ring seal ring from both sides of the multi-layer film composed of stainless steel. In addition to the role of torque, the flexible ring and the metal of the contact angle between the seat slightly blocking the Lease, the occurrence of soft ring action and radial compression, the valve seat 360-degree uniform seal around the pressure, thereby torque using the smallest to achieve the most stringent off. The choice of stainless steel butterfly valve sealing surface acid steel production, with a corrosion-resistant, high temperature, long service life characteristics.
