Connect and two ends are all that external screw thread connects, select in the present invention is: one end You Kuaicha one end is external screw thread type of attachment.
As shown in figure 3, the operation principle of EGR Delay Valve is:
EGR Delay Valve is made up of two position three-way valve, breather cheek valve, choke valve and air chamber.Compressed air is from air inlet 1 to valve
Supply, control signal inputs from control signal mouth 12, throttles through choke valve and flows into air chamber.When the air pressure in air chamber reaches valve
Operating pressure when, Vavle switching, delivery outlet 2 just has output.During exhaust, the gas of cylinder is discharged from exhaust outlet 3.
EGR Delay Valve is a kind of time control unit, and its startup symbol is as shown in Figure 4.It is to hold composition using vapour lock is gentle
Throttle blind capacitor breathing characteristic realizing inflating the delaying of signal, as shown in Figures 5 to 7.If the initial pressure in air chamber is
Zero, under conditions of temperature-resistant, after input step signal pressure p1, then the time dependent speed of air chamber internal pressure p2 depends on
In capacity-resistance time constant t.Because of t=rc, as long as so changing vapour lock r or gas appearance c so that it may the change of adjustment the blowing pressure p2 is fast
Rate, as shown in the curve of Fig. 7.Meanwhile, illustrated by the curve of Fig. 6, capacity-resistance time constant t is equal in the input of step signal pressure
Under, the blowing pressure p2 in air chamber changes to the time needed for the 63.2% of p1.Generally, the dynamic pressure of pneumatic latency valve selects
0.6p1 about.To adjust time delay length, as long as adjust choke valve aperture, time delay scope be usually 0～
30s, if in auxiliary chambers such as additional air storage tank, time delay can also extend.
EGR Delay Valve has normal open type and two kinds of nomal closed type, common are output and postpones to connect (nomal closed type), output postpones to disconnect
(normal open type).
As shown in Figure 8 and Figure 9, the operation principle of fast-discharge valve is:
As shown in Figure 8: compressed air flows into from air inlet 1, cylinder is arrived by the work gas port 2 of rapid escape valve, now
Exhaust outlet 3 is closed.
As shown in Figure 9: when the air pressure at air inlet 1 reduces, compressed air passes through work gas port 2 in air valve, passes through
Air inlet 1 is shut by seal, and exhaust outlet 3 is directly arranged outwardly.
Fast-discharge valve can increase single-acting and the opening speed of double-acting cylinder, and this can strengthen gas circuit to a certain extent
In each cylinder work uniformity, so that action is more coordinated, unanimously.
In the interface of described fast-discharge valve, muffler is set.Because fast-discharge valve is there is a problem in that when arranging soon, make an uproar
Signal to noise ratio is larger.According to plant requirements, muffler can be installed at fast-discharge valve interface 3 additional, reduce exhaust noise.
