Based on this reason an output shutoff valve that can satisfy above-mentioned requirements with flying colors has been installed.Yet these parts can not be regulated flow.For this reason, installing one can make flow keep constant, the flow control valve that not influenced by input liquid pressure.This valve can satisfy institute's requirement with flying colors.It is very important also having a bit, and promptly these two functional components should be fitted together, and liquid at utmost uncontrolledly flows out during the output shutoff valve is connected because can avoid like this.
According to our selected version, characteristics of the present invention are that the flow control valve of the influence that is not stressed has a mobile piston and a piston chamber that is subjected to the restoring force effect.Piston chamber is divided into two parts, is provided with a restriction portion between two parts.The first of piston chamber promptly on the direction of restoring force effect, has a unmodified to go into discharge orifice.Second portion has a cross section to be subjected to piston to regulate variable outlet throttling device.Adopt this design-calculated structure can obtain special stable flow rate,, and change throttle characteristics in view of the above because take such measure can reflect the ripple of pressure very sensitively in this position.
According to detailed structure of the present invention, will carry out going into head piece as restriction portion in the flow control valve of work according to pressure.In this zone, produced pressure drop thus.Like this, regulating characteristic is in the scope that more approaches delivery pressure.
According to a kind of special design form, characteristics of the present invention are that a lot of holes are arranged around the throttle chamber in the piston moving range.In piston motion direction these holes of staggering, can obtain very good flow regulating characteristic.
In order to provide restoring force, a spring has been installed to piston.In order to regulate flow afterwards obtaining desired definite numerical value, and correcting device, restoring force can be adjusted.Be provided with the screw of an adjustment spring force for this reason.
In the detailed structure provided by the present invention, also further provide the restoring force of control plunger through a temperature compensation rod.
In having according to detailed structure characteristics design-calculated flow control valve of the present invention, for example the control cock housing can be used plastics, and control plunger is made of metal.No matter be, select material all to have many good qualities like this from processing technology or from sliding capability.By adopting temperature compensation rod, compensated the het expansion of functional element under different condition, it has not only compensated because leement duration changes and altered operating characteristic, and has compensated the variation that different diameters causes operating characteristic.The material of temperature compensation rod should rule of thumb be selected.
If temperature compensation rod is contained in the mechanism of trimming screw, then structure will be simplified widely.
Press characteristics design-calculated structure example of the present invention, be described further for one by following accompanying drawing.Wherein,
The scheme drawing of Fig. 1, drinks machine mixing device,
Fig. 2, flow are constant carbonate aqueous solution output unit.
Can be selectively with different beverage concentrates and chilled CO
2The drinks machine major part that the aqueous system makes bland is that mixing channel 1(mixed process is carried out in this groove), beverage concentrate container 2(beverage concentrate enters mixing channel 1 through proportioner 3 by part from this container), and chilled CO
2This aqueous system of aqueous system holder 4(flows into mixing channel 1 through delivery valve 5 as required).Bland leaves mixing channel 1 through output hopper 6.CO in the holder
2The aqueous system is cooled off by cooling material.Cooling material is flowed through and is wrapped in conduit 7 on the holder 4.CO for delivery valve 5 outputs of flowing through in the adding container 4
2The aqueous system infeeds pure water through conduit 8 under valve system 9 controls, and under the control of valve system 12, from being full of CO
2The container 11 of gas is via conduit 10 input CO
2Gas.Resulting bland quality depends on the blending ratio of beverage concentrate and carbonate aqueous solution to a great extent.Determining of beverage concentrate consumption can be by existing, and the proportioner 3 with enough accuracy is realized.These beverage concentrates should mix mutually with the carbonate aqueous solution of respective numbers.Carbonate aqueous solution is emitted in control from holder 4 quantity is realized by delivery valve 5.The cutaway view of this delivery valve is shown in Fig. 2.Time control is undertaken by the master cock 13 of not doing expression in detail.
As shown in Figure 2, delivery valve 5 is made up of two partial function unit basically, promptly by the flow shutoff valve 14 of electromagnetic control and not the flow-controlling gate 15 of the adjusting flow of liquid body input pressure influence form.Flow shutoff valve 14 has a magnet coil 16.When the energising excitation, iron core 17 overcomes the power of spring 18 and has been carried.So a film 19 that is associated in movable core 17 lifts from valve seat.Therefore process conduit 21 can flow through shutoff valve basically by the carbonate aqueous solution of holder 4 unobstructedly.Carbonate aqueous solution flows through passage 22 and the hole on housing 23 enters in the scope of flow-controlling gate 15, and is the inflow point 24 that flows to flow-controlling gate piston chamber.Piston 25 in piston chamber is subjected to the effect of spring 26 power, promptly is pressed towards carbonate aqueous solution district's 24 the direction that becomes a mandarin.Piston end face has a metering hole 27, so the carbonate aqueous solution that has entered can arrive its second portion 28 by this hole from the first 24 of piston chamber.When flowing, on this metering hole, will produce pressure drop.
On the cylinder sleeve 30 around piston chamber's second portion 28, many holes 29 are arranged, the torus section 35 guiding delivery channels 31 on these aperture housing walls.Hole 29 is positioned within the stroke range of piston skirt.When first 24 was in high pressure conditions, it is opposite that piston is subjected to a force direction that is produced with spring 26, and the bigger pressure of numerical value.So egress hole 29 is covered manyly by piston skirt.Therefore, this position has been strengthened throttling action.If the pressure in the throttle chamber first 24 is less, then correspondingly, piston is subjected to the domination of spring 26 power that produces, and the aperture of egress hole 29 increases, and at this moment the metering function that flows through liquid has been weakened.Pass through corresponding calculated.Throttling action in delivery orifice 29 parts is directly proportional with the fluid pressure in the first of piston chamber.So constantly control the flow of carbonate aqueous solution, make it not be subjected to influence through the fluid pressure of conduit 21 input.
By corresponding time control, can determine the supply of carbonate aqueous solution very exactly.
In order to carry out in advance and with post-equalization, spring 26 can change its predetermincd tension by trimming screw 32 to flow.In this screw 32, also adorned a temperature compensation bar 33.Adorned a sleeve pipe 34 on the bar, recover spring 26 be pressed in it above, that is to say indirectly to be pressed on the valve housing.After having taked this measure, the housing of flow control valve 15, cylinder sleeve 30, piston 25 just can use the different material with different heat expansion coefficient to make with set screw 32.Repay bar 33 by means of dilatometer, different operating temperatures is not exerted an influence to the flow control valve in the system.
