Clamp Type Worm Gear Transmission Elastic Hard Seal Butterfly Valve
Product Introduction
Product Introduction And Application Of Clamp Type Worm Gear Transmission Elastic Hard Seal Butterfly Valve
This Butterfly Valve Adopts A "U" - Shaped Stainless Steel Sealing Ring, Which Is A Precision Elastic Sealing Ring That Contacts The Polished Butterfly Plate With A Three-dimensional Eccentric Sealing Area. The Organic Combination Of The Two Has Resulted In High-performance Technical Parameters Such As High Temperature Resistance, High Pressure Resistance, And Low Temperature Resistance. Therefore, It Is Widely Used In Pipelines For Corrosive Media Such As Metallurgy, Electricity, Petroleum, Chemical, Air, Gas, Combustible Gases, And Water Supply And Drainage With Medium Temperatures ≤ 550 ℃, As A Device For Regulating Flow And Cutting Off Fluids.
Characteristics Of Clamp Type Worm Gear Transmission Elastic Hard Seal Butterfly Valve
1. The Butterfly Valve Has A Simple, Compact Structure, Light Weight, Easy Installation And Disassembly, And Convenient Maintenance;
2. This Butterfly Valve Adopts A Stainless Steel "U" - Shaped Sealing Ring, Which Has A Certain Degree Of Elasticity And Can Withstand High And Low Temperatures.Under The CircumstancesIt Has Sealing Properties With The Butterfly Plate;
3. The Three-dimensional Eccentricity Of This Butterfly Valve. After Rigorous Calculation, The "U" - Shaped Sealing Ring Has Almost No Friction With The Butterfly Plate, Has A Long Service Life, And Has The Function Of Tightening As It Is Closed.
4. The Sealing Surface Of The Butterfly Plate Is Made Of Welded Cobalt Based Hard Alloy, Which Is Wear-resistant And Has A Long Service Life;
5. This Butterfly Valve Has A Unique Structure, And The "switch" Can Be Completed By Simply Rotating The Valve Stem 90 °. It Is Flexible, Convenient, Labor-saving, And Not Affected By The High Or Low Pressure Of The Medium, With Reliable Sealing Performance;
6. High Temperature Resistance, Low Temperature Resistance, And Corrosion Resistance.
