AI Technical Summary
During long-term service, the sealing pressure of existing plug valves can change due to wear, fluctuations in medium pressure, or temperature changes. This change cannot be adjusted online, leading to a decline in sealing performance and affecting pipeline operating efficiency and valve lifespan.
The valve adopts a frictionless adjustable sealing plug valve structure. Through the combination of adjusting ring, adjusting gear, adjusting rod and locking components, the axial movement of the plug and valve seat and the online adjustment of the sealing pressure can be realized, avoiding contact friction between the plug and valve seat.
It reduces operating torque, extends valve life, and allows adjustment of sealing pressure without shutting down the machine, ensuring stable sealing performance.
