이에 따라 본 출원인은 특허출원 2006-22452호(2006.03.10출원)로 복합기능을 갖는 밸브결합체를 출원한바 있으며 상기의 출원에서는 도 1 내지 도 2에 도시된 것과 같이 밸브결합체에 유체가 유입되는 유입도관(31)내에는 코일스프링(32)과 샤프트(33) 및 오링(34)에 의하여 유입되는 유체의 역류를 방지하면서 유량을 조절할 수 있는 유량조절밸브(35)가 내장되고, 유량조절밸브(35)는 메인보디(36)내의 압력이 유입도관(31)내의 압력보다 높을경우라도 코일스프링(32)에 의하여 샤프트(33)가 상승하면서 유로를 폐쇄함에 따라 유체가 역류되는 것을 방지할 수 있으며 샤프트(33)내에 형성된 유입공(37)에 의하여 유입되는 유량을 일정하게 유지할 수 있게 구성되어 있으며, 유량조절밸브(35)를 거쳐 메인보디(36)내에 유입되는 유체는 외부제어에 의하여 조작되는 솔레노이드(38)와 솔레노이드(38)와 연결된 플렌저(39)에 결합된 다이아프렘(40)에 의하여 유체의 유입을 개폐하는 개폐밸브(41)를 거쳐 유출구(42)방향으로 유체를 배출하며 유출구(42)에서 유출되는 유체가 설정압력이상일 경우 유출구(42)의 일측에 구비된 안전밸브(43)에 의하여 일정압력이상의 유체는 드레인 되게 구성되어 있으며, 또한 안전밸브(43)는 안전밸브의 하단에 구비된 핸들(44)의 조작에 의하여 안전밸브의 스프링(45)탄성을 조절하여 설정압력을 임의로 변경하는 것이 가능하게 구성되어 있다.Accordingly, the present applicant has applied for a valve assembly having a complex function as a patent application 2006-22452 (filed on March 10, 2006), and in the above application, the fluid is introduced into the valve assembly as shown in FIGS. 1 to 2. The conduit 31 has a flow control valve 35 for adjusting the flow rate while preventing the backflow of the fluid flowing by the coil spring 32, the shaft 33 and the O-ring 34, the flow control valve ( 35 may prevent the fluid from flowing backward as the shaft 33 closes the flow path by the coil spring 32 even when the pressure in the main body 36 is higher than the pressure in the inlet conduit 31. It is configured to maintain a constant flow rate introduced by the inlet hole 37 formed in the shaft 33, the fluid flowing into the main body 36 through the flow control valve 35 is operated by an external control Soleno The fluid is discharged in the direction of the outlet port 42 through the opening / closing valve 41 which opens and closes the inflow of the fluid by the diaphragm 40 coupled to the flange 38 connected to the rod 38 and the solenoid 38. When the fluid flowing out of the 42 is greater than or equal to the set pressure, the fluid having a predetermined pressure or more is drained by the safety valve 43 provided at one side of the outlet 42, and the safety valve 43 is the lower end of the safety valve. It is configured to be able to arbitrarily change the set pressure by adjusting the spring 45 elasticity of the safety valve by the operation of the handle 44 provided in the.

그러나 상기와 같은 구성은 유입되는 유체의 압력에 의하여 신축하는 코일스프링(32)이 내장되는 내장부를 형성하는 공간인 유입도관(31)과 샤프트(33)사이를 오링(34)에 의하여 상·하로 밀폐한 형태로 되어 있어 유체의 압력에 의하여 압축될시 코일스프링(32)의 반발력에 더하여 내장부의 공기압축에 의한 압력이 작용하 고, 유체의 압력이 저하되어 코일스프링(32)의 탄력에 의하여 샤프트(33)를 상승시켜야 할 경우에는 내장부의 체적이 확장됨에 따른 진공부압이 발생하여 코일스프링(32)의 탄력을 감소시키므로서, 결과적으로 유량조절밸브에 의한 정밀한 유량제어를 어렵게 하면서 유량조절의 응답속도를 지연시킨다는 문제점이 있었다.However, the configuration as described above is up and down by the O-ring 34 between the inlet conduit 31 and the shaft 33, which is a space forming a built-in portion in which the coil spring 32 is expanded and contracted by the pressure of the incoming fluid. When it is compressed by the pressure of the fluid, in addition to the repulsive force of the coil spring 32, the pressure by the air compression of the built-in portion acts, the pressure of the fluid is lowered by the elasticity of the coil spring 32 When the shaft 33 needs to be raised, a vacuum negative pressure is generated as the volume of the built-in portion expands, thereby reducing the elasticity of the coil spring 32. As a result, it is difficult to precisely control the flow rate by the flow regulating valve. There was a problem of delaying the response speed.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 코일스프링이 내장되는 내장부에 공기압축에 의한 압력이나 체적확장에 의한 진공부압이 발생하는 것을 방지할 수 있게 하는 구성을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a configuration that prevents the occurrence of pressure caused by air compression or vacuum negative pressure due to volume expansion, which is devised to solve the above problems. do.

본 고안의 또 다른 목적은 유량조절밸브에 내장되는 코일스프링의 탄성계수를 정확하게 설계할 수 있게 하고 밸브의 응답속도를 향상하여 유량을 정밀하게 제어할 수 있게 하는 것이다.Another object of the present invention is to enable precise design of the elastic modulus of the coil spring embedded in the flow control valve and to improve the response speed of the valve to precisely control the flow rate.

상기한 목적을 위한 본 고안 '복합기능을 갖는 밸브결합체의 유량조절밸브 응답속도 향상을 위한 구조'는 유량조절밸브의 구성에 있어서, 유입되는 유체의 압력에 반응하여 신축하는 코일스프링이 내장되는 내장부에 공기압축에 의한 압력이나 체적팽창에 의한 진공부압이 발생하지 않도록 내장부가 형성되는 유입도관에 내장부와 외부가 연통되는 에어벤트를 형성하여 외부의 공기와 내장부의 공기가 서로 소통될 수 있게 함으로서 내장부의 공기압을 대기압과 동일하게 유지할 수 있게 한 다.The present invention for the above purpose 'construction for improving the response speed of the flow control valve of the valve assembly having a composite function' in the configuration of the flow control valve, the built-in coil spring that expands and contracts in response to the pressure of the incoming fluid In order to prevent the pressure caused by air compression or vacuum negative pressure due to volume expansion, the air inlet and the outside communicate with each other in the inlet conduit where the internal part is formed so that the external air and the air in the internal part can communicate with each other. This allows the air pressure in the interior to be maintained at the same atmospheric pressure.

이하에서 본 고안의 바람직한 실시예에 대하여 첨부한 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 고안 '복합기능을 갖는 밸브결합체의 유량조절밸브 응답속도향상을 위한 구조'의 단면도이다.3 is a cross-sectional view of the present invention 'structure for improving the flow rate control valve response speed of the valve assembly having a composite function'.

본 고안의 상세한 설명에 앞서 본 고안의 특징적인 구성과 관련이 없는 공지된 구성과 기능에 대하여는 상세한 설명을 생략하거나 간략하게 하여 본 고안의 요지를 더욱 명확하게 하기로 하며, 본 고안의 도면기호 중 종래구성인 도 1 내지 도 2와 동일한 부분의 것은 종래기호와 동일하게 표기하기로 한다.Prior to the detailed description of the present invention for the known configurations and functions that are not related to the characteristic configuration of the present invention to omit or simplify the detailed description to make the subject matter of the present invention more clear, The same parts as in the prior art configuration of Figures 1 to 2 will be described the same as the conventional symbols.

도 3에 도시된 바와 같이 본 고안은 유량조절밸브(35)와 개폐밸브(41) 및 안전밸브(43)를 일체화한 밸브결합체로서 그 일측에는 유입도관(31)내에 코일스프링(32)과 샤프트(33) 및 오링(34)에 의하여 유입되는 유체의 역류를 방지하면서 유량을 일정하게 유지할 수 있게 하는 유량조절밸브(35)가 형성되어 있다.As shown in FIG. 3, the present invention is a valve assembly integrating a flow control valve 35, an on-off valve 41, and a safety valve 43, and at one side thereof, a coil spring 32 and a shaft in an inlet conduit 31. A flow regulating valve 35 is provided to keep the flow rate constant while preventing the back flow of the fluid introduced by the 33 and the O-rings 34.

유량조절밸브(35)는 메인보디(36)내의 압력이 유입도관(31)내의 압력보다 높을 경우 코일스프링(32)의 탄력에 의하여 샤프트(33)가 상승하면서 유로를 폐쇄함에 따라 유체가 역류하는 것을 방지하는 체크밸브기능과 함께 샤프트(33)내에 형성된 유입공(37)에 의하여 유입되는 유량을 일정하게 유지하는 복합기능을 갖도록 구성되어 있다.When the pressure in the main body (36) is higher than the pressure in the inlet conduit (31), the flow regulating valve (35) is the fluid flows back as the shaft (33) rises by closing the flow path by the elasticity of the coil spring (32) It is configured to have a combined function of maintaining a constant flow rate inflow by the inlet hole 37 formed in the shaft 33 together with a check valve function to prevent that.

유량조절밸브(35)의 코일스프링(32)은 유체의 압력변화에 신속하게 반응하여야 할 필요가 있으나 코일스프링(32)이 내장되는 내장부(46)가 유량조절밸브(35)의 유입도관(31)과 샤프트(33) 사이의 공간에 형성되어 있고 상기 공간은 상·하가 오링(34)에 의하여 폐쇄되어 있으므로 유체의 압력에 따라 코일스프링(32)이 신축하면서 내장부(46)의 체적이 감소하거나 팽창하게 되며 이때 내장부(46)의 체적변화에 따라 압력 또는 부압이 발생하게 되어 코일스프링(32)의 탄성에 영향을 미치게 되고 이에 따라 유량조절이나 응답속도에 영향을 미치게 된다.The coil spring 32 of the flow control valve 35 needs to react quickly to the pressure change of the fluid, but the internal portion 46 in which the coil spring 32 is built is an inlet conduit of the flow control valve 35. 31 is formed in the space between the shaft 33 and the upper and lower spaces are closed by the O-ring 34, so the coil spring 32 expands and contracts according to the pressure of the fluid, and thus the volume of the internal portion 46 is reduced. This decreases or expands, and a pressure or a negative pressure is generated according to the volume change of the internal part 46, thereby affecting the elasticity of the coil spring 32 and thus affecting the flow rate control or the response speed.

따라서 유량조절밸브(35)의 코일스프링(32)이 내장되는 내장부(46)는 압력이나 부압이 발생하는 것을 방지할 수 있는 구성이 필요하며 본 고안에서는 내장부(46)가 형성되는 유입도관(31)의 일측에 내장부(46)와 외부를 연통하는 에어벤트(47)를 형성함으로서 내장부(46)의 압력이 대기압 수준으로 일정하게 유지할 수 있게 구성하였다.Therefore, the built-in part 46 in which the coil spring 32 of the flow control valve 35 is built requires a configuration that can prevent the occurrence of pressure or negative pressure. By forming an air vent 47 in communication with the interior 46 and the outside on one side of (31) was configured to maintain the pressure of the interior 46 to a constant atmospheric level.

또한 에어벤트(47)는 유입도관(31)보다 다소 돌출되게 하여 외부에서 이물질 등이 쉽게 내장부로 침투하는 것을 방지하게 하였다.In addition, the air vent 47 is slightly protruded than the inlet conduit 31 to prevent foreign matters from easily penetrating into the interior.

이상에서 설명한 바와 같이 본 고안은 간단한 구성으로 유량을 조절하고 유체의 역류를 방지하는 코일스프링이 압력이나 부압에 의하여 영향을 받는 것을 해소할 수 있게 하여 유량조절밸브가 정밀하게 유압을 제어할 수 있게 하고 밸브동작의 응답속도가 지연되는 것을 방지할 수 있게 하는 효과가 있다.As described above, the present invention makes it possible to eliminate the influence of the coil spring that regulates the flow rate and prevents the backflow of the fluid by the pressure or the negative pressure with a simple configuration, so that the flow control valve can precisely control the hydraulic pressure. And it is effective to prevent the response speed of the valve operation is delayed.
