This butterfly valve system absorbs and digests foreign technology and adopts three-dimensional eccentric multi-layer metal seal structure. It is the best device for adjusting the flow rate and cutting off fluid on pipelines with metal temperature less than or equal to 550C, such as metallurgy, power, petrochemical and water supply and drainage. Features 1. The butterfly plate sealing ring is a soft and hard layered laminated metal sheet.
Turbine groove signal butterfly valve has fast, easy, safe, reliable installation, is not limited by the installation site, is convenient for the maintenance of pipes and valves, has vibration isolation and sound insulation, and overcomes the pipe connection to different shafts and produces imitation. To solve thermal expansion and contraction caused by temperature difference; reliable sealing performance
S30, S31 wafer type butterfly valve high-strength through the valve stem design has easy disassembly, reducing the misalignment of the servo and the valve stem. Primary and secondary seals: This type of seal completely isolates the fluid medium from the valve body and stem. The main seal is a pre-pressed compression cast by the machined and hand polished valve plate shoulder and valve seat.
Because the butterfly valve of this product adopts the three-dimensional eccentric principle design, the spatial trajectory of the sealing surfaces is idealized, and the sealing surfaces have no friction, no interference, and the sealing materials are properly selected, so that the sealing and corrosion resistance of the butterfly valve , High temperature resistance and abrasion resistance have been reliable. Its main features are
The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body, thereby achieving the purpose of opening and closing or adjusting. The butterfly valve is fully open to fully closed, which is usually less than 90 °. The butterfly valve and the butterfly rod itself do not have the self-locking ability. For the positioning of the butterfly plate, a worm reducer must be installed on the valve rod. Using worm reducer,
Second, the main characteristics of PTFE sealed flange butterfly valve 1. Novel design, reasonable, unique structure, light weight, rapid opening and closing. 2. The operating torque is small, the operation is convenient, and the effort is dexterous. 3. It can be installed in any position and convenient for maintenance. 4. The seals can be replaced, and the sealing performance is reliable to achieve zero leakage in two-way seals. 5.Sealing material
Butterfly valve (English: butterfly valve) refers to a valve whose disc (valve or disc) is a disk that rotates around the valve shaft to achieve opening and closing. It mainly cuts and throttles the pipeline. The butterfly valve opening and closing element is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve opening or closing or adjustment.
