상기 차단챔버(200)는 전기적 제어에 의하여 구동되는 전자변(210)을 통해 유입도관(100)에서 차압챔버(300)로 유체의 흐름을 온·오프 제어하는 공간인 것이다. 상기 차단챔버(200)의 전자변(210)은 솔레노이드 방식으로 외부의 신호에 따라 솔레노이드(220)에 의하여 플런저(230)의 왕복운동으로 다이어프램(240)을 작동시켜 유체의 흐름을 차단하거나 개방한다.The blocking chamber 200 is a space for controlling the flow of fluid from the inlet conduit 100 to the differential pressure chamber 300 through the electromagnetic valve 210 driven by electrical control. The solenoid 210 of the blocking chamber 200 operates the diaphragm 240 in a reciprocating motion of the plunger 230 by the solenoid 220 according to an external signal in a solenoid manner to block or open the flow of fluid.

또한 유량조절밸브(310)는 차단챔버(200)를 거쳐 차압챔버(300)로 유입되는 유체를 압력조절 다이아프램(315)과 압력조절스프링(330) 및 밸브샤프트(340)와 리턴스프링(341)의 상호작용에 의하여 유체의 압력과 압력조절스프링(330)의 탄성력이 평형을 이루도록 조절하여 배출구(도면 미도시)로 토출되는 유체의 압력을 일정하게 제어할 수 있게 한다.In addition, the flow control valve 310 receives the fluid flowing into the differential pressure chamber 300 via the shutoff chamber 200, the pressure control diaphragm 315 and the pressure control spring 330, the valve shaft 340 and the return spring 341. By the interaction of the) and the pressure of the fluid and the elastic force of the pressure control spring 330 is adjusted to achieve an equilibrium to control the pressure of the fluid discharged to the outlet (not shown).

상기 밸브샤프트(340)는 리턴스프링(341)과 상기 리턴스프링(341)의 전단부에 연결된 샤프트(342)와 상기 샤프트(342)의 전단부에 형성되어 유체를 배출구로 배출시키는 밸브시트(343)로 이루어짐을 특징으로 한다. The valve shaft 340 is formed on a shaft 342 connected to a return spring 341 and a front end of the return spring 341 and a front end of the shaft 342 to discharge the fluid to an outlet. It is characterized by consisting of.

또한 기존의 밸브샤프트가 디스크와 와셔와 너트로 고정이 되어 있는 반면에 도 4a에서 보는 바와 같이 본 발명에 따른 디스크(320)는 상기 디스크(320)와 상기 밸브샤프트(340)가 결합되는 부분에 상기 밸브샤프트(340)의 전단부 지름 크기 이상의 결합 홈(325)을 형성하여, 상기 도 4b에서 보는 바와 같이 상기 디스크(320)의 하단면과 상기 밸브샤프트(340)의 전단부와 결합을 상기 결합 홈(325)을 이용하여 결합하는 것으로 와셔와 너트를 사용하여 별도로 결합하지 않아도 결합상태를 유지하는 것을 특징으로 한다.In addition, while the existing valve shaft is fixed with a disk, washer and nut, as shown in FIG. 4a, the disk 320 according to the present invention is connected to the portion where the disk 320 and the valve shaft 340 are coupled. A coupling groove 325 having a diameter greater than or equal to the diameter of the front end of the valve shaft 340 is formed, and as shown in FIG. 4B, the bottom surface of the disk 320 and the front end of the valve shaft 340 are coupled to each other. By using the coupling groove 325, it is characterized in that the coupling state is maintained even without separately using the washer and nut.

그러므로 종래의 정유량 제어 밸브는 차압챔버(300)를 형성하고 있는 몸체부와 밸브샤프트(340)의 안내부가 별도로 분리되어 조립되어 있었으나 본 발명에 따 른 정유량 제어 밸브의 밸브샤프트(340)의 안내부(344)는 분리되어 있지 않고 차압챔버(300)의 몸체와 일체형으로 이루어지는 것을 특징으로 한다.Therefore, the conventional hydrostatic flow control valve has been assembled separately from the body portion forming the differential pressure chamber 300 and the guide portion of the valve shaft 340, but the valve shaft 340 of the hydrostatic flow control valve according to the present invention. The guide part 344 is not separated and is formed integrally with the body of the differential pressure chamber 300.

상기 유입도관(100)의 일측 단부에 설치된 체크밸브(120)는 메쉬망으로 이루어진 메쉬 스트레이너(110)를 유입도관(100)에 설치하여 외부에서 유입되는 유체의 불순물을 제거한 후 상기 체크밸브(120)의 조립구멍(122)에 삽입된 밸브스플(125)의 개폐를 통해 유체의 흐름을 제어하고, 유체의 역류를 방지할 수 있도록 구성된다. The check valve 120 installed at one end of the inlet conduit 100 has a mesh strainer 110 formed of a mesh network in the inlet conduit 100 to remove impurities from the fluid introduced from the outside, and then the check valve 120. It is configured to control the flow of the fluid through the opening and closing of the valve spring (125) inserted into the assembling hole (122), and prevent the back flow of the fluid.

상기와 같이 구성된 본 발명에 따른 복합기능을 갖는 정유량 제어 밸브 중 체크밸브(120)를 도 5 내지 도 6을 참조하여 상세히 살펴보면 다음과 같다.The check valve 120 of the constant flow control valve having a combined function according to the present invention configured as described above will be described in detail with reference to FIGS. 5 to 6.

상기 도 5a에서 보는 바와 같이 상기 체크밸브(120)는 상기 유입도관(100)에 내장하는 체크밸브(120)의 개폐수단인 밸브스플(125)의 지지수단을 하우징의 내부에 일체로 형성, 십자형 지지대(121)에 의해 중앙부에 위치하는 조립구멍(122)에 탄성력이 있는 고무 재질의 패킹으로 되어 있는 밸브스플(125)을 결합하는 구조로 되어 있으며, 상기 도 5b는 상기 유입도관(100)을 아래서 본 저면도이며, 상기 도 5c는 상기 유입도관(100)을 위에서 본 평면도로 상기 도 5b 내지 도 5c에 도시된 바와 같이 상기 십자형 지지대(121)의 중앙에 위치하는 조립구멍(122)에 밸브스플(125)을 삽입하여 고정되는 것을 특징으로 한다. As shown in FIG. 5A, the check valve 120 is integrally formed with a support means of the valve spur 125 that is an opening / closing means of the check valve 120 embedded in the inlet conduit 100. By the support 121, the assembly hole 122 is located in the center portion of the structure is coupled to the valve spool 125 is made of a rubber rubber packing, the Figure 5b is the inlet conduit 100 The bottom view is a bottom view, and FIG. 5C is a plan view of the inlet conduit 100 from above. As shown in FIGS. 5B to 5C, a valve is provided at an assembly hole 122 positioned at the center of the cross support 121. It is characterized by being fixed by inserting the spool (125).

이와 같은 구조의 체크밸브(120)는 상기 도 6a에서 보는 바와 같이 십자형 지지대(121) 사이에 생긴 유입공을 통해 유체가 유입되면 조립구멍(122)에 삽입된 밸브스플(125)이 유체의 압력으로 인하여 유체의 흐르는 방향으로 접혀지게 되어 상기 유체가 유입도관(100)을 거쳐 차압챔버(200)로 이동할 수 있는 것이다. 반대로 유체가 역류될 경우 상기 도 6b에서 보는 바와 같이 밸브스플(125)은 상기 조립구멍(122)의 십자형 지지대(121)로 인하여 유체의 역류하는 방향으로 접히지 않으므로 유체의 흐름을 막아 상기 유입도관(100)으로 유체가 역류되는 것을 방지할 수 있다.As shown in FIG. 6A, when the fluid flows through the inflow hole formed between the cross support members 121, the valve valve 125 inserted into the assembly hole 122 is pressurized by the pressure of the fluid. Due to this is to be folded in the flow direction of the fluid is to move the fluid through the inlet conduit 100 to the differential pressure chamber 200. On the contrary, when the fluid flows backward, as shown in FIG. 6B, the valve spline 125 does not fold in the direction in which the fluid flows back due to the cross-shaped support 121 of the assembly hole 122, thereby preventing the flow of the fluid to prevent the inflow conduit ( 100) can prevent the back flow of the fluid.
