Problems solved by technology

However, the flow area is also equal to the difference between the area of ​​the sealing surface and the area of ​​the small diameter in the middle of the valve core. Under the same flow pressure control, the force condition of the pressure regulating spring is not substantially different from that of the general direct-acting hydraulic pressure relief valve. , also not suitable for high pressure and large flow water hydraulic control system
And when the central damping hole is blocked, the damping chamber forms a local high pressure, the valve core cannot return, the overflow valve fails, and the anti-pollution ability is poor

Abstract

The invention discloses a slide damping type water hydraulic overflow valve for high-pressure and high-flow systems. The slide damping type water hydraulic overflow valve comprises a valve (1), a valve seat (2), a damping ring (3), a main valve spool (4), a damping spring (5), a damper (6), a damping valve plate (7), a spring push rod (8), an upper end cover (9), an adjusting screw (10) and a main spring (12). A water inlet (1-1), a water outlet (1-2) and an end cover mounting hole are formed in the valve (1), and circular steps are arranged at the inner bottom of the valve (1). The slide damping type water hydraulic overflow valve has the advantages that the main valve spool is subjected to differential pressure control and has extremely small movement hydraulic force effective action areas, the main spring is simple in design and manufacture under the condition of equivalent pressure and flow control, the main valve spool and the valve seat are sealed by flat plate valve structures, and accordingly the slide damping type water hydraulic overflow valve is applicable to the high-pressure and high-flow water hydraulic transmission and control systems.

Description

technical field [0001] The invention relates to the field of overflow valves, in particular to a sliding damping water hydraulic overflow valve used in high-pressure and large-flow systems. Background technique [0002] At present, in recent years, the water hydraulic transmission and control technology that directly uses water (filtered natural water, including seawater and fresh water) instead of mineral oil as the working medium has made breakthrough progress, and in a wide range of engineering applications, compared with Traditional oil-hydraulic transmission has proved to have outstanding advantages such as environmental protection, cleanliness, high efficiency, convenient use and maintenance, and low operating cost. Water hydraulic transmission and control technology has been widely used in high-pressure water atomization, seawater desalination, high-pressure water cleaning, stage drive and control, submersible buoyancy adjustment system, marine engineering and other t...
