Description
Technical field
The utility model relates to a kind of liquid distributor proportional valve, especially to the valve of micro liquid accurate quantification.
Background technology
At present, because the restriction of process technology and the material property and the market demand, particularly liquid body distributing box and proportional valve demand chamber molding technology thereof condition restriction, atomizing cone proportional valve commonly used quantitatively is generally 30 μ l～200 μ l, but in some special purposes, because liquid distributor and proportional valve addition, interpolation precision influence bigger to product quality, need to adopt the liquid distributor proportional valve below the quantitative volume 20 μ l of hydrojet, and existing proportional valve is owing to be subjected to structural limitations, all out of reach requirements.In existing national sector standard, there is not hydrojet quantitatively less than the liquid distributor proportional valve of 30 μ l yet, there is not manufacturing enterprise produce to give birth to make hydrojet quantitatively less than the liquid distributor proportional valve of 30 μ l yet.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, provide a kind of addition little, add the precision height, quantitatively less than the micro liquid distributing box proportional valve of 15 μ l, to satisfy specific demand.
The purpose of this utility model is achieved by the following technical solution.
A kind of liquid distributor proportional valve, mainly comprise actuator, be positioned at actuator below and with the contacted valve rod of actuator, be set in the outer valve body of valve rod, be arranged at body cavity and be positioned at the valve rod below retracing spring, be connected in valve body bottom and the pipette that communicates with body cavity, be set in valve body hypomere and the outer liquid bottle of pipette, it is round table-like that described valve body is that inner chamber and profile are gradually little from top to bottom step; The epimere of valve rod is inner cylinder with vertical spill cavity, hypomere is that gradually little from top to bottom step is round table-like, outside the first order of external diameter maximum and next-door neighbour's second stage column body segment, all offer annular groove, in each annular groove, all be fitted with the O RunddichtringO and cooperate with valve seal; Spill cavity is communicated with actuator inner chamber and body cavity respectively by the side overflow hole of top end opening and bottom, and the annular groove of first order column body segment is led in the side overflow hole.
The utility model also is fitted with bottle cap on liquid bottle, bottle cap is placed on the valve body epimere by the circle hole sleeve on the capping, and the actuator cover is placed on the bottle cap.The end junction that screws at bottle cap and valve body is provided with packing seal.On the sidewall of valve body, offer the through hole that connects wall thickness.
The utility model structure has broken through traditional proportional valve D-M (Determiner-Measure) construction, and addition is little, interpolation precision height.Especially the O RunddichtringO D-M (Determiner-Measure) construction that is adopted can realize being accurate to the micro quantitative determination of 5-15 μ l.The utility model is simple in structure, and is easy to use.
Below in conjunction with Figure of description, the utility model is elaborated.

The specific embodiment
As shown in the figure, the utility model mainly comprise actuator 1, be positioned at actuator below and with the contacted valve rod 2 of actuator, slidably be set in the outer valve body 5 of valve rod, be arranged at body cavity and be positioned at the valve rod below retracing spring 6, be connected in the valve body bottom and the pipette 8 that communicates with body cavity, be set in valve body hypomere and the outer liquid bottle 7 of pipette.Described valve body 5 is round table-like for inner chamber and profile are gradually little from top to bottom step, offers the through hole 13 that connects wall thickness on the sidewall of valve body as shown in Figure 5, is used for the air pressure of balance cock inside and outside.Valve rod 2 as shown in Figure 3, Figure 4, epimere is inner cylinder with vertical spill cavity 9, hypomere is that gradually little from top to bottom step is round table-like, outside the first order of external diameter maximum and next-door neighbour's second stage column body segment, all offer annular groove, in each annular groove, all be fitted with O RunddichtringO 11,12 and cooperate with valve seal; Spill cavity 9 is communicated with actuator inner chamber and body cavity respectively by the side overflow hole 10 of top end opening and bottom, and the annular groove of first order column body segment is led in side overflow hole 10.Also can be equipped with bottle cap on liquid bottle 7, bottle cap 4 is placed on the valve body epimere by the circle hole sleeve on the capping, and actuator 1 cover is placed on the bottle cap, and valve rod 2 passes with actuator 1 from the liquid distributor bottle cap and is connected.The end junction that screws at bottle cap and valve body is provided with packing seal 3.On actuator 1, can offer an inner chamber 14, the open communication on intracavity bottom and valve rod spill cavity 9 tops, the object that needs can be added feed liquid for example cigarette props up and inserts in the inner chamber 14.
When actuator was not subjected to the external force effect to be in not pressured state, as shown in Figure 1, overflow weir 10 was blocked by O RunddichtringO 11.Retracing spring 6 one ends press on valve rod 2 lower ends, and the other end is pressed in valve body 5 outlet inwalls, forms being linked of valve rod 2 and actuator 1.The line of centers of actuator 1, valve rod 2, valve body 5, bottle cap 4 is positioned on the axis, makes the power transmission of valve rod more even.When actuator 1 is subjected to the external force effect and is in pressured state, as shown in Figure 2, valve rod 2 overcomes action of reset spring power and presses downward to, when valve rod 2 was depressed into valve body 5 bottoms, valve body 5 bottoms were by 12 sealings of O RunddichtringO, and the liquid quilt that is in the valve body 5 is quantitative, O RunddichtringO 11 is dug slightly at this moment, liquid enters spill cavity 9 by overflow weir 10, and is ejected into the object that inserts the actuator inner chamber 14 from the opening on spill cavity 9 tops, for example the cigarette termination of propping up.When the external force that is applied to actuator 1 was removed, retracing spring was upspring, and valve rod 2 and actuator 1 reset thereupon, and O RunddichtringO 11 is got back to original position, and overflow weir 10 is blocked by O RunddichtringO 11, and the sealing of valve body 5 bottoms is simultaneously removed, and liquid reenters in the valve body 5.
The spouting liquid of this proportional valve is less than 15 μ l, and the hydrojet precision can reach ± 2 μ l.
