Operation principle：
As shown in figure 8, when electromagnetic coil 19 is powered, 12 suction moment of magnet increases, and the first armature 11 is inhaled, together
When, the first armature 11 drives the first mandril 20 and the second mandril 21 that auxiliary valve core 24 is pushed to move downward, by the upper end of auxiliary valve core 24
It opens, lower end is closed.
At this point, right end high pressure gas is ended by the lower end of auxiliary valve core 24 so that in the cavity of main valve plug 6 and auxiliary valve core 24
High pressure gas enters the upper end of auxiliary valve core 24 by the through-hole 2703 on supporting disk 8, is discharged using the outlet of valve seat 1.
Simultaneously as the upper end of main valve plug 6 is low-pressure gas, lower end is high pressure gas, and pressure difference overcomes the first spring 7
Elastic force pushes main valve plug 6 open upwards, i.e., main valve plug 6 is opened, and gas passes through.
As shown in figure 9, when electromagnetic coil 19 powers off, due to the negater circuit of electromagnetic coil 19, electromagnet 12 generates row
Repulsion pushes the first armature 11 open upwards.At this point, second spring 25 pushes auxiliary valve core 24 open upwards, 24 upper end of auxiliary valve core is closed,
It opens 24 lower end of auxiliary valve core.High pressure gas enters the upper end cavity of main valve plug, about 6 main valve plug by 24 lower end of auxiliary valve core simultaneously
Pressure difference pushes down on main valve plug 6, and main valve plug 6 is closed.
When electromagnet is not powered, third spring 14 is open-top by the first armature 11 and the second armature 13.At this point, the first armature 11
With at a distance from magnet 12 be more than the distance between the first mandril 20 and the second mandril 21.
When the solenoid is energized, the second armature 13 just starts that the elastic force of third spring 14 is overcome to move downward, the first mandril
20 also and then move downward.When the first mandril 20 and the second mandril 21 contact, the second armature 13 overcomes the first spring 7, second
Spring 25 and 24 cavity gas pressure of auxiliary valve core push auxiliary valve core 24 to move downward, and so that 24 lower end of auxiliary valve core is closed, upper end is beaten
It opens.
According to dynamic balance relation, the presence of third spring 14 can make second spring 25 be changed to the smaller spring of rigidity, i.e.,
For auxiliary valve core 24 when being turned on and off, second spring 25 reduces the active force of auxiliary valve core 24.According to seal pressure condition, into one
Step can be such that the bore dia in second seal 26 increases, that is, so that the flow area of pilot section is increased, shorten main valve plug 6
Response time more rapidly opens main valve plug 6.
