A kind of throttle orifice plate apparatus provided by the invention, it comprises shell and is located at the interior orifice plate with through hole of shell, described orifice plate can endwisely slip with respect to described shell, in the shell of these orifice plate both sides, be respectively equipped with elastic telescopic parts and spool, described elastic telescopic parts one end is connected with orifice plate, and the other end is fixedlyed connected with shell; Described spool is fixedlyed connected with described shell, is used for regulating the flow that fluid flows through described through hole when described orifice plate slides with respect to described shell.
Preferred as technique scheme, described spool comprise with the coaxial spool body of described through hole and are located at this spool body near the valve core head of described orifice plate one end that this valve core head can insert in the described through hole.
Preferred as technique scheme, the side of described valve core head is the conical surface, the conical surface that the part or all of internal face of described through hole is complementary for the side with described valve core head.
Preferred as technique scheme, diameter was little in the middle of the two ends diameter of described through hole was big.
Preferred as technique scheme, described spool also comprises is located at described spool body away from the base of described orifice plate one end, and described spool is fixedlyed connected with described shell by this base, is provided with the fluid passage at this base.
Preferred as technique scheme, described spool comprises the spool body and is located at this spool body near the valve core head of orifice plate one end that the area of this valve core head end face is greater than the cross-sectional area of described through hole.
Preferred as technique scheme also comprises block, and this block is fixed in described orifice plate in the described shell of a side of described elastic telescopic parts.
Preferred as technique scheme, described elastic telescopic parts are spring.
Preferred as technique scheme also comprises annular base plate, and described elastic telescopic parts are fixedlyed connected with described shell by described annular base plate away from an end of orifice plate.
The air-conditioning unit adopts throttle orifice plate apparatus provided by the invention, when its standard condition oepration at full load, because there is pressure reduction in the orifice plate both sides, controls the initial opening of orifice plate through hole by the decrement of elastic telescopic parts, can guarantee specified throttling demand.Under variable working condition, variable load operation, when load reduced, condensing pressure reduced or evaporating pressure raises, and the pressure reduction of orifice plate both sides reduces, and orifice plate is toward spool one side shifting, and orifice size reduces, and flow reduces, thereby satisfies the requirement of little load.When load rises, condensing pressure reduces or evaporating pressure raises, the pressure reduction of orifice plate both sides raises, and orifice plate is toward elastic telescopic parts one side shifting, and orifice size increases, flow increases, satisfy the requirement of big load, this shows, throttle orifice plate apparatus provided by the invention can be regulated flow automatically according to the variation of system pressure, realized under different operating modes, different load, guaranteeing to be complementary to liquid supply rate and the evaporation load of evaporimeter, thereby guaranteed performance and the regulating power of unit.
Compared with prior art, advantage of the present invention is: throttle orifice plate apparatus provided by the invention, can regulate flow automatically according to the variation of system pressure before and after the orifice plate, make under different operating modes, different load, to guarantee to be complementary to liquid supply rate and the evaporation load of evaporimeter, improved performance and the regulating power of unit.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated:
Embodiment 1
As shown in Figure 1, throttle orifice plate apparatus mainly is made of shell 7, orifice plate 4, spool 2 and spring 5, and wherein, shell 7 is cylindric, and orifice plate 4 is located in the shell 7, and with shell 7 matched in clearance, so orifice plate 4 can endwisely slip with respect to shell 7.Be provided with the through hole 4a that passes through for fluid at the middle part of orifice plate 4, the internal face of this through hole 4a is the conical surface.Preferably, the big middle diameter of the two ends diameter of through hole 4a is little.
In the shell 7 of a side of spring 5, be provided with block 3 at orifice plate 4.When block 3 contacts with orifice plate 4, there is the gap between valve core head 2b and the through hole 4a, guarantee that by block 3 start process aperture plate 4 has certain initial opening.
The operation principle of above-described embodiment is: the air-conditioning unit is when the standard condition oepration at full load, and there is pressure reduction in orifice plate 4 both sides, controls the initial opening of orifice plate 4 through hole 4a by the decrement of spring 5, can guarantee specified throttling demand.Under variable working condition, variable load operation, when load reduced, condensing pressure reduced or evaporating pressure raises, and the pressure reduction of orifice plate 4 both sides reduces, orifice plate 4 side shifting of turning left, and orifice size reduces, and flow reduces, and satisfies the requirement of little load.When load rose, condensing pressure reduced or evaporating pressure raises, the rising of orifice plate 4 both sides, and orifice plate 4 movement of turning right, orifice size increases, and flow increases, and satisfies the requirement of big load.This shows, the throttle orifice plate apparatus of present embodiment can be according to the variation of system pressure and is regulated flow automatically, realized under different operating modes, different load, guaranteeing to be complementary to liquid supply rate and the evaporation load of evaporimeter, thereby guaranteed performance and the regulating power of unit.
As shown in Figure 2, as different from Example 1, the area of the valve core head 2b end face of present embodiment is greater than the cross-sectional area of through hole 4a, like this, when orifice plate 4 endwisely slips with respect to valve core head 2b along with the variation of system pressure, also can regulate the fluid flow size through through hole 4a, thereby reach the purpose of automatic adjusting flow.
In sum, the core of throttle orifice plate apparatus of the present invention is: orifice plate 4 slides with respect to valve core head 2b along with the variation of system pressure, and then regulates fluid by valve core head 2b and flow through the flow of through hole 4a, thereby reaches the purpose of automatic adjusting flow.Therefore, valve core head 2b and through hole 4a can also be other structures except the described structure of above-described embodiment, and this will become apparent to those skilled in the art that again and repeats no more.
Be specific embodiments of the invention only below, do not limit protection scope of the present invention with this; Any replacement and the improvement done on the basis of not violating the present invention's design all belong to protection scope of the present invention.
