Screen pack 521 is for being filtered to injection pressure oil in control port 210, preventing pressure influence the application's
Performance.
Here is the specific work process of the application：
When the application is in close, main valve plug 520 is crushed on the first valve seat 200 due to the spring force of second spring 510
Step on so that oil inlet 220 and oil return opening 230 cannot be mutually communicated, and guide valve core 420 is by the first spring 410
The side of the second valve seat 300 is pressed on, so as to ensure that the cut-off between oil inlet 220 and oil return opening 230.
When the application is opened, fluid can be entered into second spring chamber 500 by oil inlet 220, and controls the oil to lead to
Control port 210 is crossed to be flowed into the damping hole of main valve plug 520, so that whole second spring chamber 500 is full of, when pressure oil continues to note
Fashionable, in the damping hole that pressure oil can be entered on the second valve seat 300, then pressure oil can be acted on guide valve core 420, until
The pressure of control port 210 more than the first spring 410 support elastic force when, at this moment pressure oil will promote guide valve core 420 along
First spring 410 is moved to the direction of adjusting rod 430, and at this moment, the fluid in second spring chamber 500 can be by the second valve seat 300
Aperture, be flowed into the first spring cavity 400, and flowed out by oil return opening 230, until stopping injection control in control port 210
Liquefaction.
Cause the misoperation of the application to prevent oil inlet 220 and oil return opening 230 from communicating, on the second valve seat 300
Sealing ring 301 is also equipped with, while in order to avoid the excessive leakage of oil return opening 230, leading between the valve seat 200 of main valve plug 520 and first
The conical surface is crossed to be sealed.
In addition, if oil return opening 230 have by pressure pressure then can be due to oil return opening 230 it is completely enclosed without influence sequence valve
Closing performance, if any larger by pressure pressure, the application is also provided with aperture 521 on main valve plug 520, and aperture 521 can be by pressure
Cause inside main valve plug 520, by this pressure balance.Simultaneously because the presence of aperture 521, can discharge pressure oil rapidly, make suitable
Sequence valve quick closedown.
