After liquid enters accumulation of energy annular groove by decompression throttle orifice, the work of the liquid retained in the effect and accumulation of energy annular groove due to accumulation of energy
With under the liquid medium buffer function that the high-speed liquid medium flowed into from outside retains in accumulation of energy annular groove, flow velocity will be quick
It reduces, the liquid medium retained in accumulation of energy annular groove by high-speed liquid when being impacted, liquid the rushing high-speed liquid that retains
Energy absorption is hit, and reduces the impact energy of high-speed liquid, also will just reduce be transferred to rushing on annulus wall and pressure reducing disc in this way
Power is hit, the impact energy for receiving pressure relief assembly is substantially reduced, and it reduces high-speed liquid and washes away to the destruction inside pressure reducing disc, thus
It prolongs its service life.
2, the pressure reducing disc of the pressure relief assembly of the utility model is due to using fastening up and down to dress mode, the energy after assembling
Guaranteeing enough reduction of speed annular channels, the decompression throttle orifice of punching press can use uneven distribution mode on each annulus wall, as long as
Guarantee enough decompression areas at different levels.
3, the utility model solves the cavitation damage of regulating valve, mainly by the way of multi-step pressure reduction, in multi-step pressure reduction
Every level-one all consume part energy so that the inlet pressure of next stage is relatively low, reduce the pressure difference of next stage, pressure is extensive
It is multiple to reduce, the intensity of cavitation is reduced, and design accumulation of energy annular groove in every level-one relief outlet, accumulation of energy annular groove can make flow rate of liquid
It quickly reduces, forms opposite static pressure field, slow down the direct impact between each pressure reduction stage, can effectively improve the anti-of pressure relief assembly
Fatigue capability.
4, the processing and forming of lower-cost accurate heat stamping and shaping can be used in the utility model, changes original
Galvano-cautery, electric carving carve contour cost processing technology, greatly reduce the production cost of regulating valve.And the assembling letter of the utility model
Just, the manufacturing cost of regulating valve is significantly reduced.
