Abstract

PURPOSE: A proportional control valve is provided to improve accuracy of proportional control by mechanically controlling total flow amount discharged into plural outflow passages. CONSTITUTION: A proportional control valve comprises a valve body(1), a main valve(2), and plural flow control valves. The valve body discharges fluids flowed through an inflow passage(8) to a main outflow passage through plural flow control outflow passages. The main valve is fixed at the front side of the valve body. The main valve opens and shuts a valve seat(8-1) formed at the inlet portion of the inflow passage depending on the conduction state of a coil(21), with using a poppet(25) of a plunger(23). The flow control valves are fixed at the rear side of the valve body. The flow control valves are selectively controlled to open and shut each inlet of the flow control outflow passage, with using the poppet of the plunger depending on the conduction state of the coil. The total flow amount can be controlled by properly controlling the stroke of the plunger and the diameter of the flow control outflow passage through a mechanical control, and therefore accurate control is performed.

Description

비례제어밸브{PROPORTIONAL CONTROL VALVE}Proportional Control Valve {PROPORTIONAL CONTROL VALVE}

본 발명은 비례제어밸브에 관한 것으로, 더욱 상세하게는 하나의 밸브몸체에한 개의 유입로와 다수의 유출로를 설치하고, 다수의 유출로을 유출되는 총유량을 기계적으로 다단계 제어할 수 있는 비례제어밸브에 관한 것이다.The present invention relates to a proportional control valve, and more particularly, to install one inflow path and a plurality of outflow paths in one valve body, and proportionally control the mechanical multi-step control of the total flow rate flowing out of the plurality of outflow paths. It is about a valve.

일반적으로, 솔레노이드를 이용한 비례제어밸브는 일정한 전원을 코일에 공급하는 것이 아니라 코일에 공급되는 전원의 크기를 제어함으로써 가동철심에 유도되는 전자력의 크기를 제어하게 되고, 이로써 스풀의 이동거리를 제어할 수 있는 밸브를 말한다.In general, the proportional control valve using a solenoid controls the magnitude of the electromagnetic force induced by the moving core by controlling the magnitude of the power supplied to the coil instead of supplying a constant power to the coil, thereby controlling the moving distance of the spool. Says a valve that can.

그러나, 이러한 비례제어밸브는 코일에 공급되는 전원크기에 따라 스풀의 이동거리를 정확한 제어하기 위해서 가동철심의 마찰저항, 압축스프링의 탄성력, 코일의 정렬권선 등 각 부품의 정밀도가 요구된다.However, such proportional control valves require the precision of each component, such as frictional resistance of the moving core, elastic force of the compression spring, and winding winding of the coil, in order to accurately control the moving distance of the spool according to the size of the power supplied to the coil.

더욱이, 비례제어밸브는 각 부품의 정밀도가 확보되었다 하더라도 전자기적인 노이즈나 전압의 불규칙한 입력, 온도에 의한 저항의 증가 등으로 제어조건이 변화될 수 있고, 그 대량생산이 어려울 뿐만 아니라 가격도 고가이다.Moreover, even if the accuracy of each part is secured, the proportional control valve can change the control conditions due to electromagnetic noise, irregular input of voltage, and increase in resistance due to temperature, and its mass production is difficult and expensive. .

결국, 종래의 비례제어솔레노이드밸브는 전자적인 제어에 의해 공급유량을 제어하는 방식으로, 유량제어에 영향을 주는 내외적인 변수를 가공공정에 반영하여야 하기 때문에 여러가지 문제를 초래하게 된다.As a result, the conventional proportional control solenoid valve causes various problems because the internal and external variables affecting the flow control must be reflected in the processing process in a manner of controlling the supply flow rate by electronic control.

본 발명은 하나의 밸브몸체에 한 개의 유입로와 다수의 유출로를 설치하고, 스트로크를 달리하는 밸브를 이용하여 각 유출로의 입구측에 설치된 동일직경의 밸브시트(8-1)를 선택적으로 개폐하거나 동일한 스트로크를 갖는 밸브를 이용하여 각각 다른 직경으로 만들어지는 밸브시트(8-1)를 선택적으로 개폐함으로써 다수의 유출로로 유출되는 총유량을 기계적으로 다단계 제어하여 비례제어의 정밀도를 향상시킨 비례제어밸브를 제공함에 그 목적이 있다.According to the present invention, one inlet passage and a plurality of outlet passages are provided in one valve body, and valve seats 8-1 having the same diameter are installed selectively at the inlet side of each outlet passage using a valve having a different stroke. By selectively opening and closing the valve seat 8-1 made of different diameters by using a valve having the same stroke, the total flow rate flowing out of the multiple outflow paths is mechanically multi-stage controlled to improve the accuracy of the proportional control. The purpose is to provide a proportional control valve.

상기한 목적을 달성하기 위하여 본 발명은 를 제공한다.In order to achieve the above object, the present invention provides a.

도면을 참조하여 본 발명을 설명한다.The present invention will be described with reference to the drawings.

도1은 본 발명에 따른 비례제어밸브를 나타내는 평면도이고, 도2는 도1의 B-B 단면도이며, 도3은 도1의 A-A 단면도이고, 도4는 본 발명에 따른 비례제어밸브의 제1실시예를 나타내는 작동상태도이며, 도5는 본 발명에 따른 비례제어밸브의 제2실시예를 나타내는 작동상태도이다.1 is a plan view showing a proportional control valve according to the present invention, FIG. 2 is a sectional view taken along line BB of FIG. 1, FIG. 3 is a sectional view taken along line AA of FIG. 1, and FIG. 4 is a first embodiment of the proportional control valve according to the present invention. 5 is an operating state diagram showing a second embodiment of a proportional control valve according to the present invention.

본 발명에 따른 비례제어밸브에 있어 밸브몸체(1)에는 그 내측중앙에 유입로(8)가 형성되어 있고, 이 내측하부에 메인유출로(10)가 설치되어 있으며, 유입로와 메인유출로가 다수의 유량제어유출로(9)에 의해 연결되도록 형성되어 있다.In the proportional control valve according to the present invention, the valve body 1 has an inflow path 8 formed at the inner center thereof, and the main outflow path 10 is installed at the lower part of the inner side thereof. Is formed to be connected by a plurality of flow control outlets (9).

이때, 유입로(8)의 입구측에 위치하도록 밸브몸체(1)에 고정 설치되는 메인밸브(2)는 유입로의 입구측에 마련된 밸브시트(8-1)()을 개폐하도록 설치되어 있다.At this time, the main valve 2 fixed to the valve body 1 so as to be located at the inlet side of the inlet passage 8 is provided to open and close the valve seat 8-1 () provided at the inlet side of the inlet passage. .

다시 말하면, 메인밸브(2)는 코일(21)에 공급되는 전원을 차단하게 되면 압축스프링(24)의 탄성력에 의해 플런저(23)가 전진되면서 포펫(25)이 밸브시트(8-1)를 차단하게 되고, 코일(21)에 전원을 공급하게 되면 플런저(23)가 후진되면서 포펫(25)이 밸브시트(8-1)를 열게 되는 구조이다.In other words, when the main valve 2 cuts off the power supplied to the coil 21, the plunger 23 is advanced by the elastic force of the compression spring 24, and the poppet 25 opens the valve seat 8-1. When the power is supplied to the coil 21, the plunger 23 is reversed and the poppet 25 opens the valve seat 8-1.

그리고, 유입로(8)로 유입되는 유체는 각 유량제어유출로(9)를 통해 메인유출로(10)로 배출하게 되는데, 이 유체의 공급과정에서 다수의 유량제어밸브(2-1)는각 유량제어유출로(9)의 입구에 설치되어 유량제어유출로로 유입되는 유량을 제어하도록 설치되어 있다.In addition, the fluid flowing into the inflow path 8 is discharged to the main outflow path 10 through each flow control outlet path 9, and in the process of supplying the fluid, the plurality of flow control valves 2-1 are each It is provided at the inlet of the flow control outlet 9 to control the flow rate flowing into the flow control outlet.

즉, 유량제어밸브(2-1)는 상시닫힘형 솔레노이드밸브로서, 코일(3)에 공급되는 전원을 차단하게 되면 압축스프링(11)의 탄성력에 의해 플런저(5)가 전진되면서 포펫(6)이 각 유량제어유출로(9)의 각 입구를 선택적으로 완전 차단하게 되고, 코일(3)에 전원을 공급하게 되면 플런저(5)가 설정스트로크(a)만큼 후진되면서 포펫(6)이 유량제어유출로의 각 입구를 선택적으로 열게 되는 구조이다.That is, the flow control valve 2-1 is a normally closed solenoid valve, and when the power supply to the coil 3 is cut off, the plunger 5 is advanced by the elastic force of the compression spring 11 and the poppet 6 is moved. Each inlet of each flow control outlet 9 is selectively shut off completely. When power is supplied to the coil 3, the plunger 5 moves backward by the set stroke a, and the poppet 6 controls the flow. It is a structure that selectively opens each inlet of the outflow passage.

이때, 다수의 유량제어밸브(2-1)는 각각 코일(3)에 전원이 공급되었을 때 코어(4)측으로 후진되는 플런저(5)의 스트로크(a)를 달리 설정하여 포펫(6)에 의한 유량제어유출로(9)의 열림정도를 각각 다르게 함으로써 유량제어유출로의 입구로 유출되는 유량을 제한하게 된다.At this time, the plurality of flow control valve (2-1) is set by the poppet (6) by differently setting the stroke (a) of the plunger (5) which is reversed to the core (4) side when the power is supplied to the coil (3), respectively By varying the opening degree of the flow control outlet 9, the flow rate flowing out to the inlet of the flow control outlet is limited.

또한, 유량제어유출로(9)의 직경을 각각 다르게 형성하거나 모두 동일하게 형성하여 포펫(6)에 의해 선택적으로 개방되는 유량제어유출로의 입구로 유출되는 유량을 제어할 수 있게 된다.In addition, it is possible to control the flow rate flowing out to the inlet of the flow control outlet flow path is selectively opened by the poppet (6) by forming the diameter of the flow control flow path (9) differently or all the same.

이하, 각 실시예를 통해 본 발명의 비례제어밸브를 더욱 상세히 설명하기로 한다.Hereinafter, the proportional control valve of the present invention through each embodiment will be described in more detail.

먼저, 본 발명에 따른 비례제어밸브의 제1실시예를 살펴보면, 도4에 도시한 바와 같이 유량제어유출로(9)의 직경을 모두 동일하게 형성하는 동시에 플런저(5)의 스트로크(a)를 달리 설정한 후, 유량제어밸브(2-1)를 각각 선택적으로 제어함으로써 각 유량제어유출로를 통해 메인유출로(10)로 유출되는 총유량을 다단계적으로 정밀하게 제어할 수 있게 된다.First, referring to the first embodiment of the proportional control valve according to the present invention, as shown in Fig. 4, the diameters of the flow control outlet 9 are all the same, and at the same time, the stroke a of the plunger 5 is formed. After setting differently, by selectively controlling the flow control valve (2-1), respectively, it is possible to precisely control the total flow rate flowing out to the main outflow path (10) through each flow control outflow path.

이때, 코일(3)에 선택적으로 통전이 이루어지면 스트로크(a)를 달리하는 플런저(5)가 후진되면서 포펫(6)과 유량제어유출로(9)의 입구 간의 간격이 각각 다르고, 이에 따라 동일직경의 유량제어유출로를 통한 유출유량이 달라지게 된다.At this time, if the coil 3 is selectively energized, the distance between the poppet 6 and the inlet of the flow control outlet 9 is different while the plunger 5 having a different stroke a is reversed, and thus the same. The flow rate through the flow control outlet of the diameter is changed.

결국, 각 유량제어밸브(2-1)의 작동을 선택적으로 제어할 경우 메인유출로(10)를 통해 유출되는 총유량은 여러단계로 정밀하게 조정될 수 있게 된다.As a result, when selectively controlling the operation of each flow control valve (2-1), the total flow rate flowing out through the main outflow path 10 can be precisely adjusted in several steps.

그리고, 본 발명에 따른 비례제어밸브의 제2실시예는 도5에 도시한 바와 같이 각 플런저(5)의 스트로크(a)가 동일하도록 설정하는 대신에 유량제어유출로(9)의 직경을 각각 달리 형성함으로써 유량제어유출로를 통한 유출유량을 다르도록 한 후, 각 유량제어밸브(2-1)를 선택적으로 제어하여 상기 제1실시예와 같은 총유출유량의 다단계 제어효과를 거둘 수 있게 된다.In the second embodiment of the proportional control valve according to the present invention, instead of setting the strokes a of the plungers 5 to be the same as shown in FIG. 5, the diameters of the flow control outlet 9 are respectively set. By forming differently, the flow rate through the flow control outlet is different, and then, each flow control valve 2-1 is selectively controlled to achieve the multi-stage control effect of the total flow rate as in the first embodiment. .

그 외에도 플런저(5)의 스트로크(a)와 유량제어유출로(9)의 직경에 있어 그 상관관계를 적절히 조합할 경우 상기 제1실시예 및 제2실시예와 같은 총유출유량의 다단계 제어효과를 거둘 수 있게 된다.In addition, if the correlation between the stroke a of the plunger 5 and the diameter of the flow control outlet 9 is properly combined, the multi-stage control effect of the total flow rate as in the first and second embodiments is the same. Will be able to reap.

본 발명은 플런저의 스트로크와 유량제어유출로의 직경을 적절히 조합함으로써 총유출유량을 다단계적으로 제어할 수 있고, 그 제어방식이 기계적으로 이루어져 오작동없이 정밀하게 제어할 수 있는 효과를 제공하게 된다.The present invention can control the total flow rate in multiple stages by appropriately combining the stroke of the plunger and the diameter of the flow rate control flow passage, the control method is mechanically provided to provide an effect that can be precisely controlled without malfunction.
