Description

파이로트식 솔레노이드 밸브의 숨구멍 막힘 방지장치{omitted}Preventing pore clogging of pilot solenoid valves

본 발명은 파이로트식(간접식) 솔레노이드 밸브에 관한 것으로, 이물질에 의하여 솔레노이드 밸브 내부에 설치된 다이아프램(7)의 숨구멍(5)이 막혀서, 솔레노이드 밸브가 오동작 하는 것을 방지하는 것과 동시에, 유체가 원활하게 통과하도록 구성하는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pilot (indirect) solenoid valve, wherein the pores (5) of the diaphragm (7) provided inside the solenoid valve are clogged by foreign matter, thereby preventing the solenoid valve from malfunctioning, and at the same time the fluid It is configured to pass smoothly.

도 1에 도시한 파이로트식 솔레노이드밸브에 대하여 살펴보면, 솔레노이드 밸브의 내부에 설치되어 있는 플런저(6)는 솔레노이드 코일(1)에 전자기력이 발생하면 동 자기력에 의하여 상승할 수 있도록 구성되며, 스프링(10)에 의하여 아래로 탄성 지지되어 있다. 그리고 다이아프램(7)은 유체입출구가 평면으로 만나는 밸브 체임버 상부에 설치되어, 그것을 통하여 내부의 유체 흐름을 단속하게 된다.Referring to the pilot solenoid valve shown in Figure 1, the plunger 6 is installed inside the solenoid valve is configured to rise by the dynamic magnetic force when the electromagnetic force generated in the solenoid coil (1), the spring ( 10) is elastically supported downward. And the diaphragm 7 is installed in the upper part of the valve chamber where the fluid inlet and outlet meet in a plane, it is to interrupt the fluid flow therein.

위 솔레노이드코일(1)에 전원이 인가되어 플런저(6)가 상승하게 되면, 플런저(6)에 의하여 막혀있던 다이아프램(7)의 센터 구멍(3)이 열리게 되어 다이아프램(7)) 상부의 공간에 차있던 유체가 다이아프램의 센터 구멍(3)을 통하여 빠지게 되면서 다이아프램 숨구멍(5)을 통하여 공급되는 유체에 의해서, 유체압력과 똑같은 압력으로 유지되던 다이아프램 상부 공간의 유체압력이 떨어지게 된다.When power is applied to the upper solenoid coil 1 and the plunger 6 rises, the center hole 3 of the diaphragm 7 blocked by the plunger 6 opens to open the upper portion of the diaphragm 7. As the fluid filled in the space is released through the center hole 3 of the diaphragm, the fluid pressure in the upper diaphragm space maintained at the same pressure as the fluid pressure is dropped by the fluid supplied through the diaphragm pore 5. .

이로 인하여 다이아프램(7) 상부 공간 압력보다 솔레노이드 밸브의 유입구에 서 가해지는 다이아프램(7) 하부의 유체압력이 높아지게 되므로 이 유체의 압력에 의하여 다이아프램(7)이 상부로 들려 져서 유체가 입구에서 출구로 흐를 수 있게 된다.As a result, the fluid pressure of the lower part of the diaphragm 7 applied at the inlet of the solenoid valve is higher than the diaphragm 7 upper space pressure. Therefore, the diaphragm 7 is lifted upward by the pressure of the fluid, and the fluid is introduced. To the exit.

그리고 솔레노이드 코일(1)에 전원이 차단되면 스프링(10)의 장력에 의하여 상기 플런저(6)가 아래로 이동하게 되어, 플런저 하단부가 다이아프램의 센터구멍(3)을 막게 되면, 다이아프램의 숨구멍(5)을 통하여 다이아프램의 상부 공간으로 유체가 공급되면서 다이아프램(7) 상부와 하부의 유체압력이 동일하게 되어 유체의 흐름이 차단되는 것이다.When the power supply to the solenoid coil 1 is cut off, the plunger 6 moves downward due to the tension of the spring 10. When the lower part of the plunger obstructs the center hole 3 of the diaphragm, the pores of the diaphragm As the fluid is supplied to the upper space of the diaphragm through (5), the fluid pressure of the upper and lower parts of the diaphragm 7 becomes the same, thereby blocking the flow of the fluid.

이러한 구조를 가지는 공지의 파이로트식 솔레노이드 밸브는 다이아프램(7)에 설치되는 2개의 구멍(3),(5) 중에서 하나만 막혀도 밸브로서의 기능을 잃어버리게 되므로 위 2개의 구멍들 보다 작은 구멍을 구비한 필터를 유체 입구에 설치하게 된다.The known pilot solenoid valve having such a structure loses its function as a valve even if only one of the two holes (3) and (5) installed in the diaphragm (7) loses its function as a smaller hole than the above two holes. The provided filter is installed at the fluid inlet.

그러나 유체입구에 필터를 설치하게 되면, 필터의 저항으로 인하여 유량이 감소하게 되는 것은 물론이고, 다이아프램의 숨구멍(5) 직경보다 더 작은 구멍들을 구비한 미세필터를 설치하여야 하는데, 이 필터에 이물질이 축적되면 아예 유체가 통과하지 못하는 수도 있다.However, when the filter is installed at the fluid inlet, the flow rate decreases due to the resistance of the filter, and a micro filter having holes smaller than the diameter of the diaphragm pore 5 should be installed. If this builds up, fluid may not pass at all.

따라서 주택의 온수난방관 같이 녹물 등의 이물질이 포함된 물이 통과하는 곳에 필터를 장착한 솔레노이드 밸브를 장착하게 되면, 단기간 내에 난방용 온수가 통과하지 못하는 일이 발생할 수 있어 여러 가지로 어려운 문제가 발생한다.Therefore, when a solenoid valve equipped with a filter is installed in a place where water containing foreign substances such as green water flows through, such as a hot water heating tube of a house, the hot water for heating may not pass within a short period of time, causing various problems. do.

통형의 필터가 막히면 청소가 어렵고, 구조상 워터해머가 발생한다.If the cylindrical filter is clogged, it is difficult to clean, and water hammer is generated in structure.

본 발명은 위항과 같은 문제점을 해결하기 위한 것으로, 유량의 공급을 확실하게 하면서 이물질에 의하여 다이아프램의 숨구멍이 막히지 않게 하는 것이다.The present invention is to solve the above-mentioned problems, to ensure the supply of flow rate so that the pores of the diaphragm is not blocked by foreign matter.

솔레노이드 밸브의 바디 부분 중, 다이아프램(7) 숨구멍(5)의 바로 아래 위치에, 숨구멍(5)의 내경보다 외경이 작은 봉(2)을 구비하여, 숨구멍(5)으로 관통시키도록 설치하고, 솔레노이드 밸브의 유체 입구에는 필터를 설치하지 않는 방법으로 해결하는 것이다.In the body portion of the solenoid valve, a rod 2 having a smaller outer diameter than the inner diameter of the pore 5 is provided at a position just below the diaphragm 7 pore 5 so as to penetrate through the pore 5. To solve this problem, do not install a filter in the fluid inlet of the solenoid valve.

본 발명에 의하면 솔레노이드 밸브 바디의 입구에 설치하던 필터를 제거하므로 약간의 이물질이 포함된 유체라 하더라도 원활하게 통과되고, 전체의 통과 유체 중, 아주 적은 양의 압력조절용 유체가 통과하는 다이아프램의 숨구멍(5)은, 숨구멍을 관통하여 설치한 봉(2)이, 솔레노이드 밸브 다이아프램(7)의 상하개폐 작동에 의하여, 숨구멍에 침착되는 각종 이물질의 청소작용을 하게 되므로, 유체속에 포함된 이물질이 숨구멍에 부착할 여유를 주지 않게 되어 숨구멍(5)과 센터구멍(3)이 막히지 않게 되는 것이다.According to the present invention, the filter installed at the inlet of the solenoid valve body is removed, so that even a fluid containing some foreign matter passes smoothly, and a small amount of the diaphragm pores through which a very small amount of pressure regulating fluid passes. (5) is a rod (2) provided through the pores to clean the various foreign matters deposited in the pores by the opening and closing operation of the solenoid valve diaphragm (7), foreign matter contained in the fluid The pore 5 and the center hole 3 will not be blocked because the pore will not be allowed to attach to the pore.

그리고 기존방법(실용신안 20-0379895호 참조)에서 많이 발생하는 워터해머 가 현저하게 줄어드는 효과도 있다.In addition, there is a significant reduction in the number of water hammers generated by the existing method (see Utility Model 20-0379895).

공지의 솔레노이드 밸브에서는 상기한 바와 같이 다이아프램(7)에 센터 구멍(3)과, 숨구멍(5)의 2개 구멍이 있는데, 이곳을 통과하는 유체의 양은 전체 유체량에 비하여 거의 무시할 정도로 소량이라 ,다이아프램의 센터구멍(3)과 숨구멍(5)의 크기도 아주 작아서 이물질에 막히기 쉬운 단점이 있어 온수난방분배기와 같이 이물질이 많이 발생하는 곳에는 사용할 수가 없었다.In the known solenoid valve, as described above, the diaphragm 7 has two holes, a center hole 3 and a pore 5, and the amount of fluid passing through the diaphragm 7 is negligibly small compared to the total amount of fluid. The diaphragm center hole (3) and pores (5) are also very small in size, which makes it easy to be clogged by foreign matters.

이에 본 발명의 구성은 솔레노이드 밸브의 바디 부분 중, 다이아프램(7)의 숨구멍(5)의 바로 아래 위치에, 숨구멍(5)의 내경보다 외경이 작은 봉(2)을 구비하여 숨구멍(5)을 관통시키도록 설치하는 것이다.Therefore, the structure of this invention is provided in the position of the solenoid valve body just below the pore 5 of the diaphragm 7, and has the rod 2 whose outer diameter is smaller than the inner diameter of the pore 5, and has the pore 5 It is to be installed to penetrate.

이렇게 함으로서 숨구멍(5)에 관통 설치된 봉(2)과 그보다 내경이 조금 큰 숨구멍(5)의 틈새로 아주 소량의 압력조절용 유체가 공급되게 되는데, 파이로트식 솔레노이드 밸브는 개폐 작동시에 다이아프램(7)이 상하로 움직이게 되므로 숨구멍(5)도 상하로 움직이게 되어, 숨구멍(5)을 관통하여 설치된 봉(2)에 의하여 수시로 청소가 되므로 이물질에 의하여 숨구멍(5)이 막히는 사례가 거의 없게 되는 것이다.In this way, a very small amount of pressure-regulating fluid is supplied into the gap between the rod 2 installed through the pore 5 and the pore 5 having a larger inner diameter. The pilot solenoid valve is a diaphragm ( 7) is moved up and down, so the pore (5) is also moved up and down, and is often cleaned by the rod (2) installed through the pore (5), so that the pores (5) is hardly clogged by foreign matter. .
