AI Technical Summary

Technical Problem

During use of the existing flow and pressure regulating valve, water flow directly acts on the ring seat, causing wear and affecting the sealing effect, and the guide component is impacted, affecting the sealing and pressure regulating effects.

Method used

A flow and pressure regulating valve is designed, including a valve frame, a valve assembly, a power device, an energy dissipation assembly and an adjustment assembly. The kinetic energy of the flowing medium is consumed by the energy dissipation assembly, and the flow area is adjusted by the cooperation of the No. 2 threaded guide and the valve frame. Combined with the extrusion seal of the sealing cover, the key components are protected.

Benefits of technology

It reduces the impact of the flowing medium on the sealing cover, prolongs the service life of the sealing cover, stabilizes the water flow velocity, reduces cavitation, and ensures the sealing effect and reliability of the flow and pressure regulating valve.

Abstract

The application discloses a flow-regulating and pressure-regulating valve and a regulating mode thereof, and relates to the technical field of flow-regulating and pressure-regulating valves.The flow-regulating and pressure-regulating valve comprises a valve frame, the inside of the valve frame is fixedly connected with a placing frame, a valve assembly for controlling the medium flow area is installed between the valve frame and the placing frame, and a power device for controlling the valve assembly is installed in the inside of the placing frame.The cooperation between the second threaded flow guide and the valve frame can realize the energy consumption of the second threaded flow guide to the flowing medium based on the rotation of the second threaded flow guide, meanwhile, the first sealing cover and the second sealing cover can realize the closing of the flow-regulating and pressure-regulating valve, the impact of the flowing medium on the first sealing cover and the second sealing cover is reduced through the energy consumption of the flowing medium, the abrasion of the first sealing cover and the second sealing cover is reduced, meanwhile, the first sealing cover is stored in the protection cylinder through the adjusting assembly, and the protection of the first sealing cover is realized.
