Description
Technical field
The utility model belongs to valve field, is related to a kind of throttling one-way valve.
Background technology
Hydraulic control one-way valve is often applied in pressurize, pressure release, is locked in loop.Due in pressure maintaining period in system, because pressure is big,
Fluid compression, pipe expansion, element occur elastic deformation etc. can storing energy, in pressure release, kidney amount discharges suddenly, and
When reversal valve is from middle position to left position, because hydraulic cylinder upper cavity pressure is larger, cavity pressure is now descended to raise, unloading valve is several with main valve
Open simultaneously, the pressure oil of epicoele is discharged into oil return line by hydraulic control one-way valve suddenly.Because the two reasons are deposited simultaneously
And pressure release is too fast after making pressurize, produce impact shock and noise, we are improved such hydraulic circuit for this.Due to
It is too fast that high-pressure high-flow hydraulic control one-way valve result in pressure release, increases impact, adds a choke valve in the loop for this, so as to
Hydraulic control one-way valve unloading valve is first opened, then open main valve again, because choke valve has enough flow-control scopes, can protect
Stable minimum discharge is demonstrate,proved, easy to adjust, leakage is small, and temperature and pressure is also small to influenceing.
The valve class that check valve and choke valve be combined with each other is referred to as throttling one-way valve at present, now in hydraulic system
