Abstract
The utility model relates to a numerically controlled electromagnetic valve set used for controlling fluid flow rate. The utility model is composed of electromagnetic valves, control holes, a switch tube, etc. A movable magnetic head is arranged on each electromagnetic valve, each movable magnetic head is corresponding to one control hole, and effective areas of each control hole is consistent with the position value of a binary digit represented by the control hole. A computer or a digital integrated circuit can be used for controlling fluid flow rate, which is simple, accurate and reliable for controlling. The utility model is suitable for all occasions needing controlling the fluid flow rate, and the utility model is eapecially suitable for gas water heaters, automobile oil piping systems, hydraulic systems, gas and oil generator systems, etc.
Description
The numerical control electromagnetic valve group belongs to a kind of control valve of controlling fluid flow.
Present oscillatory type solenoid valve is the make-and-break time flow of control flows body recently by control valve, and its pulsation is big, and noise is also big.Control the proportion expression solenoid valve of fluid flow by the size of control valve opening, though can overcome these shortcomings, because the linearity of magnetic material is bad, thereby the control difficulty is big, and validity is poor.
The purpose of this utility model is to provide a kind of several chambeies electromagnetic valve group that can directly realize accurate, stable, reliable and good linearity with the binary number fluid flow.
The utility model is made up of single solenoid valve, control hole, switching tube etc., it is characterized in that: a moving magnetic head is all arranged on each single solenoid valve of a.; B. each moving magnetic head is all corresponding to a control hole.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing 1 is a schematic representation of the present utility model.
In the accompanying drawings, [1] is electromagnetic valve group, and it is by single solenoid valve A, B, C ... Deng being fine into jointly.A moving magnetic head [3] is all arranged on each single solenoid valve.Each moving magnetic head [3] all corresponding a control hole [4].Moving magnetic head [3] is mainly used in closes or breakdown control hole [4].Control hole [4] is done on the dividing plate between import [2] and the outlet [5].The area of each control hole [4] perforate is consistent with the place value of the binary number of its representative.For example, the control hole [4] that the moving magnetic head [3] on the single solenoid valve A is corresponding is represented first of binary number, and the area of its perforate is 1 * 2
0=1; The control hole [4] that moving magnetic head [3] on the single solenoid valve B is corresponding is represented second of binary number, and the area of its perforate just is 1 * 2
1=2; The control hole [4] that moving magnetic head [3] on the single solenoid valve C is corresponding is represented the 3rd of binary number, and the area of its perforate just is 1 * 2
2=4.In electromagnetic valve group [1], single solenoid valve can also be more more, the pairing control hole of the Electrical heads of the single solenoid valve of after this each, and the binary digit of its representative and perforated area all can the rest may be inferred.Electromagnetic valve group [1] is linked to each other with the binary system control circuit, and the break-make that makes single solenoid valve is consistent with the Binary Zero of its representative or 1, and the actual internal area of the fluid that electromagnetic valve group [1] is controlled is exactly the binary numeral of a change.Under certain pressure, the Fluid Volume that passes through from import [2] to outlet [5] is then consistent with binary numeral.Suppose that the pairing control hole of single solenoid valve A is open-minded, the pairing control hole of solenoid valve B.C is closed, and represents binary number 001, and at this moment, the flow of fluid is exactly the product of the area of pressure and 1 representative; Suppose that again the pairing control hole of solenoid valve A.B closes, the pairing control hole of solenoid valve C is open-minded, represents binary number 100, and at this moment the flow of fluid is exactly the product of the area of pressure and 4 representatives; Suppose that the more pairing control hole of solenoid valve A.B.C is all open-minded, represent binary number 111, at this moment flow should be the product of the area of pressure and 7 representatives.Solenoid valve single in the electromagnetic valve group [1] is many more, and the control number is just big more.The variable of the electromagnetic valve group control of for example being made up of five single solenoid valves is 32, and the variable that the electromagnetic valve group of being made up of six single solenoid valves is controlled is 64.The control of switching tube [6] extremely directly (or through buffer circuit) links to each other with computer or digital integrated electronic circuit, can constitute good fluid control mode.
The utility model can directly be controlled the flow of fluid with computer or digital integrated electronic circuit, control is simple, accurate, reliable, be applicable to that all need control the occasion of fluid flow, be specially adapted to gas water-heater, automotive oil system, gentle, the fry dried food ingredients electric system of hydraulic system.
Claims (2)
1. numerical control electromagnetic valve group, by single solenoid valve, control hole, compositions such as switching tube is characterized in that:
A. on each single solenoid valve a moving magnetic head is arranged all;
B. each moving magnetic head is all corresponding to a control hole.
