(other are excellent so that the pressure signal in the chamber C that crosses is conveyed to pressure gauge 5 by first preferable layout scheme as an example below
Select placement scheme its principle identical with this) illustrate the operation principle of knob pressure regulator valve of the present invention：
For introduce it is convenient for the sake of, it is assumed herein that fluid working substance be gas working medium (other fluid working substance principles are identical with this,
No longer describe in detail), the epigyny device such as the compressor pump head 15 or gas tank 16 that come from pressure regulator valve that the chamber A that now becomes a mandarin receives
Gas working medium, the outflow lumen B of the high pressure conditions of (referring to Figure 13) are then to the slave device such as pneumatic tool, nailing of pressure regulator valve
Rifle, spray gun for paint, air nozzle etc. are supplied；For different use objects, can in advance using turn knobs 6 obtain different precessions or
Strategy is screwed out to obtain the effect of setting pressure in different modulating outflow lumen B, wherein Fig. 9 show gas in setting outflow lumen B
The situation of power pressure and the pressure state for being allowed to be in higher, for convenience of describing, it is assumed that the relief piston 9 shown in Fig. 9 is
Plummet be laid out and pressure regulation core body 8 in upper, relief piston 9 under, in addition in the present case assume rotation set 7 spiral structure 7a be dextrorotation
Screw thread is constructed, that is, it obtains the downward i.e. so-called precession of moving displacement or cry feeding, revolves counterclockwise when turning clockwise
It obtains the i.e. so-called back-out of upward moving displacement or recalls and moves back when turning；It should be noted that the spiral shell of rotation set of the invention 7
Rotation construction 7a can also construct for left hand thread, now to obtain think precession effect must then go counterclockwise driving rotation set 7；In figure
In the middle of situation shown in 9, the slave device of pressure regulator valve not yet enables or is in the state of break-off, and now operating personnel press
According to default modulated pressure rotationally clockwise knob 6 with order about rotation set 7 make further precession action, it is necessary to modulation
Pressure is more high, and rotation set 7 needs more precession more；Generally by the position of the selected precession of knob 7 of the modulated pressure numerical value demarcated in advance
Put, and gas pressure, pressure spring 10 in the cross-sectional area of the modulated pressure demarcated and relief piston 9, outflow lumen B is firm
Degree coefficient (being also stiffness factor) and drift etc. are closely related, therefore required modulated pressure must in advance design and calculate and want
Demarcate in advance and the good corresponding numerical value of correspondence is matched on pressure gauge 5, so that staff selects and operates；With rotation set 7
Precession its pass through to be pressed against face D contact and push pressure regulation core body 8 dynamics it is bigger, in other words compressed by pressure regulation core body 8 and adjusted
Pressing spring 10 and the acting force of the spring that is allowed to act on relief piston 9 further increases, and finally cause the acting force of the spring
Upper top active force more than same purpose in relief piston 9 (pushes up active force for the gas working medium in the C of chamber that crosses acts on pressure regulation on this
Gas load on piston 9 acts on the summation of the contact force on relief piston 9 with balance valve core 2, and friction is neglected herein
Power), then relief piston 9 is forced to move down and drive balance valve core 2 also to follow simultaneously to move down, and as a result the envelope of balance valve core 2 breaks stream
The situation of interface channel 4 is broken between chamber A and the chamber C that crosses, then the company that the gases at high pressure working medium piggybacking in the A of chamber that becomes a mandarin is opened
Connect road 4 and enter and cross in the C of chamber and be further supplemented in outflow lumen B (referring to 9), it is noted that the slave device of pressure regulator valve
Not yet enable or be in the state of break-off, these cavitys such as the chamber C that now crosses, outflow lumen B, air pressure sensing passage 12 and
Gas pressure in passage is of substantially equal and their numerical value is slightly lower than the gas pressure numerical value become a mandarin in chamber and (covers because of connection
Caused by there are certain throttle effect at passage 4), in be accompanied by gases at high pressure working medium constantly from the chamber A that becomes a mandarin fill into
Cross chamber C (also meaning to be added into outflow lumen B), then the gas pressure in the C of chamber that crosses also rises immediately, then acts on pressure regulation
Gas load on piston 9 will also rise therewith, when the gas load and balance valve core 2 are acted on relief piston 9
When contact force sum acts on the acting force of the spring on relief piston 9 more than pressure spring 10, at this moment relief piston 9 again quilt
Lifting and upper shifting simultaneously ultimately result in balance valve core 2 and seal connection breaking passage 4 again, are thus developed to the reaching setting shown in Figure 10 and adjust
The situation of pressing pressure, the equilibrium state that now relief piston 9 is obtained is to be determined by knob 6 and the default modulated pressure value of rotation set 7,
And the precession degree that rotation set 7 is selected is echoed, under state shown in Figure 10, the slave device of pressure regulator valve is not yet enabled or is in
Gas pressure in these cavitys such as the state of break-off, the chamber C that now crosses, outflow lumen B, air pressure sensing passage 12 or passage
It is equal；When consuming the gas working medium in outflow lumen B without breaking in working order at the slave device of pressure regulator valve (referring to Figure 11),
Now the gas pressure in outflow lumen B will decline, and what is mutually echoed therewith is that the upper top active force for raising relief piston 9 diminishes,
When active force is pushed up less than default modulated pressure on this, the suppressing action of pressure spring 10 is in the spring effect on relief piston 9
Power is opened up gets the upper hand, and when acting force of the spring is more than the upper top active force for acting on relief piston 9 is above pushed away, relief piston 9 is again
Moved down and pushed up out balance valve core 2 and be again turned on interface channel 4, the then above-mentioned action to outflow lumen B tonifying Qi again will again

Stream chamber B) in gas working medium escape to leaking from pressure release passage 9a and final via the bleed passage 17 being opened on pressure regulation core body 8
External environment is escaped into, with leaking for gas working medium, the gas pressure crossed in chamber C and outflow lumen B is also rapid therewith to be declined,
The pressure spring 10 then set up pushes the acting force of the spring of relief piston 9 and finally defeats the gas load crossed in the C of chamber,
Then relief piston 9 can be moved down and finally so that the pressure release passage 9a on relief piston 9 is balanced valve element 2 and seals disconnected again again, this
When via pressure release passage 9a the stopping that leaking, the pressure of the gas working medium in chamber C (including outflow lumen B) that then crosses reaches institute
The modulated pressure of setting is simultaneously balanced herein；If pressure regulator valve bottom instrument is started working and is disappeared at position shown in Figure 12 instantly
Gas working medium in consumption outflow lumen B, the then gas pressure in the C of chamber that crosses can further decline again, and until upper top active force (is handed over
The gas load that gas working medium is acted on relief piston 9 in remittance chamber C acts on connecing on relief piston 9 with balance valve core 2
The summation of touch) acting force of the spring that pushes relief piston 9 less than pressure spring 10 (notes the acting force of the spring and the institute of knob 6
The modulated pressure of setting is related), then relief piston 9 is forced to move down and drive balance valve core 2 also to follow simultaneously to move down and the company of opening
Road 4 is connected, then similar with above situation, chamber A will be recurred once again to the tonifying Qi action of outflow lumen B and process from becoming a mandarin
(not shown), the result is that the gas pressure of outflow lumen B can be maintained in predetermined relatively low working pressure range.
