Description

펌프의 실링수 공급밸브 {SEALING WATER SUPPLY VALVE OF PUMP}Sealing water supply valve of pump {SEALING WATER SUPPLY VALVE OF PUMP}

본 발명은 펌프의 실링수 공급밸브에 관한 것으로, 특히 펌프를 기동하기 전에 실링수 공급을 위해 정전기력을 통해 실링수 보조밸브를 개방하고 그런 후에 충분히 펌프의 만수작업이 종료되면서 펌프를 가동시켜 펌프의 수압으로 실링수 주밸브를 개방할 수 있도록 한다.The present invention relates to a sealing water supply valve of a pump, and in particular, to open the sealing water auxiliary valve through the electrostatic force for supplying the sealing water before starting the pump, and then operate the pump while the pump is fully filled. Allow the water pressure to open the sealing water main valve.

통상적으로, 펌프, 예컨대 취수펌프가 가동하여 유체 수송을 가능하게 하려면 우선 흡수면보다 높은 곳에 위치하여 있는 취수펌프 내부에 유체가 채워져야 한다. 이를 위해서, 진공펌프를 가동하여 취수펌프 내부의 공기를 충분히 흡입하여 진공상태를 유지시켜 대기압에 의하여 한강 흡수정의 물이 펌프의 중심까지 밀려올라오게 된다. 펌프 내부가 유체로 채우는 만수작업으로, 펌프가 가동되어 펌프 케이싱 내부의 회전차가 회전을 시작하여 유체 수송이 가능해진다. Typically, a fluid, such as a water intake pump, must first be filled inside a water intake pump located above the absorbing surface in order to enable fluid transport. To this end, the vacuum pump is operated to sufficiently suck the air inside the intake pump to maintain a vacuum state so that the water of the Han River absorption well is pushed up to the center of the pump by atmospheric pressure. In a full water operation in which the inside of the pump is filled with fluid, the pump is operated so that the rotation difference inside the pump casing starts to rotate and fluid transport is possible.

만수작업은 취수펌프에서 진공펌프에 연결된 진공배관과 솔레노이드밸브를 통해 수행된다. 구체적으로, 취수펌프 가동스위치가 켜지면, 우선적으로 진공펌프 가 가동되고 그런 다음에 솔레노이드밸브가 개방되어 공기를 흡입한다. 펌프 케이싱 내부는 대기압에 의하여 유체가 채워지게 되고, 이와 같이 유체가 채워지면 만수감지기가 이를 감지하여 취수펌프를 가동시킨다. 펌프가 가동되면서, 진공변이 폐쇄되고 그런 다음에 진공펌프가 꺼지게 되며, 펌프 내부에 적당한 압력이 형성되면 토출밸브가 개방되어 취수펌프의 가동이 완료된다.The filling operation is carried out by means of a solenoid valve and a vacuum pipe connected to the vacuum pump in the intake pump. Specifically, when the intake pump operation switch is turned on, the vacuum pump is first operated, and then the solenoid valve is opened to suck in air. The inside of the pump casing is filled with fluid by atmospheric pressure, and when the fluid is filled in this way, the water level sensor detects this and starts the intake pump. As the pump is operated, the vacuum valve is closed and then the vacuum pump is turned off. When a suitable pressure is formed inside the pump, the discharge valve is opened to complete the operation of the intake pump.

특히, 그랜드 패킹은 펌프축이 케이싱을 관통하는 부분의 스터핑 박스 내에 설치되어 펌프 가동중 외부공기가 펌프 임펠러의 흡입구로 흡입되는 것을 차단할 뿐만 아니라 액이 외부로 누출되는 것을 방지한다. 하지만, 축과 패킹 사이에 상대운동이 존재하기 때문에 마찰과 마모에 의한 열이 발생되는 문제점을 갖는바, 이러한 열을 냉각하기 위해서 패킹의 내·외부 중간에 랜턴 링을 삽입하고 이곳에 외부로부터 실링수를 주입하여 패킹의 냉각과 윤활 및 밀봉작용을 도모할 수 있다.In particular, the gland packing is installed in the stuffing box of the portion where the pump shaft penetrates the casing, which not only prevents external air from being sucked into the inlet of the pump impeller while the pump is running, but also prevents liquid from leaking to the outside. However, there is a problem that heat is generated by friction and abrasion because there is a relative motion between the shaft and the packing.In order to cool this heat, a lantern ring is inserted between the inside and the outside of the packing, and the outside is sealed here. Water can be injected to achieve cooling, lubrication and sealing of the packing.

당해분야의 숙련자들에게는 이미 널리 주지되어 있듯이, 패킹의 냉각과 윤활 및 밀봉작용을 위하여, 실링수가 효과적으로 공급되어야 한다. 종래의 실링수 공급밸브는 상시 개방되어 있어, 펌프의 휴지 중에도 불필요하게 실링수를 공급하고 있어, 실링수의 낭비와 전력에너지의 손실을 초래하고 있다. 취수펌프가 휴지상태에 있을 때의 일반적인 실링수의 배출상황을 고려하면, 펌프 외부로 배출되어 육안으로 관찰할 수 있는 누수는 드레인 배관을 타고 배수 집수정으로 흐르며 수시로 배수펌프를 가동하여 펌프장 밖으로 배출시켜야 하는 한편, 펌프 내부에서의 실링수 누수는 랜턴 링 안쪽으로 펌프 흡입케이싱으로 흘러, 흡입관을 타고 다시 한강 흡수정으로 역류하게 되는데, 이러한 배관 내부의 누수는 외관적으로 눈에 보이지 않 아, 누수되는 실링수가 많은 경우에도 누수 방지에 적절한 대처가 어려운 게 현실이다. 이와 같이 실링수의 누수를 근본적으로 차단하여 에너지 절약 및 예산절약을 기해야할 것이다.As is well known to those skilled in the art, for cooling, lubricating and sealing the packing, the sealing water must be supplied effectively. The conventional sealing water supply valve is always open and supplies the sealing water unnecessarily even when the pump is stopped, resulting in waste of the sealing water and loss of power energy. Considering the general discharge condition of the sealing water when the intake pump is at rest, leaks that can be observed outside the pump and visible to the naked eye flow through the drain pipe to the drainage basin and are often discharged out of the pump station by operating the drain pump. On the other hand, the sealing water leak inside the pump flows into the pump suction casing inside the lantern ring, which flows back to the Han River absorption well through the suction pipe, which is not visible in appearance. Even in the case of a large number of sealing seals, it is difficult to properly cope with leakage. As such, the leakage of sealing water should be fundamentally blocked to save energy and save budget.

본 발명은 전술된 다수의 단점들을 해결하기 위해 창출된 것이다.The present invention has been created to solve many of the disadvantages described above.

특히, 본 발명은 펌프가 휴지상태에서는 실링수의 공급밸브가 자동으로 폐쇄되어 실링수의 공급을 원천적으로 차단하는 반면에, 펌프를 가동하면 실링수의 공급밸브가 수압과 전자기력에 의해서 자동으로 개방되어 실링수를 공급할 수 있도록 되어 있는 것을 특징으로 한다.Particularly, in the present invention, while the pump is at rest, the supply valve of the sealing water is automatically closed to block the supply of the sealing water, whereas when the pump is operated, the supply valve of the sealing water is automatically opened by hydraulic pressure and electromagnetic force. It is characterized in that the sealing water can be supplied.

본 발명은 실링수의 공급을 자동으로 제어할 수 있어 실링수를 이루는 수돗물의 누수를 차단하여 수돗물 절약 및 예산절감효과를 야기할 것이다.The present invention can automatically control the supply of the sealing water to block the leakage of the tap water forming the sealing water will cause tap water saving and budget saving effect.

이상 본 발명의 설명에 의하면, 본 발명에 따른 펌프의 실링수 공급밸브는 전자기력과 수압을 통해 공급밸브를 개방하고 펌프의 휴지 시에는 공급밸브를 폐쇄하여 실링수의 공급을 효과적으로 제어할 수 있도록 제공된다.According to the description of the present invention, the sealing water supply valve of the pump according to the present invention is provided to open the supply valve through the electromagnetic force and water pressure and to close the supply valve when the pump is stopped to effectively control the supply of the sealing water. do.

또한, 본 발명의 실링수 공급밸브를 통해 불필요하게 펌프에 실링수를 공급하지 않게 되어 실링수(수돗물)의 누수를 근본적으로 제거하여 예산절감을 실현할 수 있다.In addition, through the sealing water supply valve of the present invention, the sealing water is not unnecessarily supplied to the pump, thereby fundamentally eliminating leakage of the sealing water (tap water), thereby realizing budget savings.

본 발명의 실링수 공급밸브는 전술되었듯이 실링수의 공급을 제어할 수 있어 실링수 누수로 인해 펌프 외부로 실링수가 누출되지 않아 종래에 펌프 외부로 누출된 실링수를 펌프실 밖으로 배출하기 위한 별도의 수고를 요구하지 않게 된다.As described above, the sealing water supply valve of the present invention can control the supply of the sealing water so that the sealing water does not leak to the outside of the pump due to the leakage of the sealing water. No effort is required.

이제, 본 발명에 따른 펌프의 실링수 공급밸브는 첨부도면을 참조로 하여 더욱 상세하게 설명한다.Now, the sealing water supply valve of the pump according to the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 실링수 공급밸브를 구비한 펌프의 개략도이다.1 is a schematic diagram of a pump having a sealing water supply valve.

본 발명에 따른 실링수 공급밸브(1)는 수압을 통해 주밸브(도 2 참조)를 개방할 수 있도록 펌프(100) 본체에 부착된 수압배관(101)과 정수배관(102) 사이에 위치된다. The sealing water supply valve 1 according to the present invention is located between the hydraulic pressure pipe 101 and the purified water pipe 102 attached to the main body of the pump 100 so as to open the main valve (see FIG. 2) through hydraulic pressure.

또한, 실링수 공급밸브(1)는 실링수 공급을 위해 일차적으로 전원을 통해 보조밸브(도 2 참조)를 개방하도록 설계되어 있으므로 소정의 전원을 요구한다. 이를 위해서, 진공배관(103)에 설치된 솔레노이드 밸브(104)로 유도된 전원이 실링수 공급밸브(1)용 전원으로 동시에 사용할 수 있게 배선한다. 선택가능하기로, 실링수 공급밸브(1)용 전원은 다양한 방법으로 동원될 수 있음을 미리 밝혀둔다. 이러한 배선과정은 본 발명의 명료한 이해를 위해서 그리고 당해분야의 숙련자들에게는 이미 널리 알려진 주지된 기술로 상세한 설명은 배제하도록 한다.In addition, since the sealing water supply valve 1 is designed to open the auxiliary valve (see FIG. 2) through the power supply primarily for sealing water supply, a predetermined power supply is required. To this end, the power guided to the solenoid valve 104 provided in the vacuum pipe 103 is wired so that it can be used simultaneously as the power supply for the sealing water supply valve 1. Selectively, it is noted that the power source for the sealing water supply valve 1 can be mobilized in various ways. This wiring process is to be omitted for the sake of clarity of understanding of the present invention and the well-known techniques already well known to those skilled in the art.

실링수 공급밸브(1)는 전술된 바와 같이 보조밸브가 개방되어 소정의 실링수가 펌프 내부로 유입되고 완전히 만수되면 펌프(100)를 가동한다. 펌프(100)의 가동으로, 수압이 형성되어 수압배관(101)을 따라 유도된 물이 주밸브를 밀어붙여 실링수를 정상 공급시킬 수 있도록 한다. As described above, the sealing water supply valve 1 operates the pump 100 when the auxiliary valve is opened so that the predetermined sealing water flows into the pump and is completely filled. By the operation of the pump 100, water pressure is formed so that the water guided along the water pressure pipe 101 pushes the main valve so that the sealing water can be normally supplied.

실링수 공급밸브(1)의 작동원리는 도 3을 통해 더욱 구체적이면서 명료하게 설명하도록 한다.The operating principle of the sealing water supply valve 1 will be described more specifically and clearly through FIG. 3.

도 2는 본 발명에 따른 실링수 공급밸브의 단면도이다.2 is a cross-sectional view of the sealing water supply valve according to the present invention.

도시된 바와 같이, 본 발명의 실링수 공급밸브(1)는 그 내부에 주밸브(10)와 보조밸브(20)를 구비하고 있다. 특히 실링수의 공급을 효과적으로 제어하기 위해, 실링수 공급밸브(1)는 수압배관(101)과 정수배관(102)의 교차점에 위치되는 것이 바람직하다. As shown, the sealing water supply valve 1 of the present invention has a main valve 10 and an auxiliary valve 20 therein. In particular, in order to effectively control the supply of the sealing water, the sealing water supply valve 1 is preferably located at the intersection of the hydraulic pipe 101 and the purified water pipe 102.

또한, 실링수 공급밸브(1)의 주밸브(10)와 보조밸브(20)는 정수배관(102)을 개폐할 수 있도록 정수배관(102)의 내부를 가로질러 배열된 차단막(30)을 구비하는바, 이 차단막(30)의 중심부는 주밸브(10)와 보조밸브(20)가 안착될 수 있게 천공되어 있다. 주밸브(10) 또는 보조밸브(20)가 차단막(30)에서 이탈되면 천공부(31;도 3 참조)를 통해 정수배관(102)의 실링수가 펌프로 유입될 수 있는 한편, 주밸브(10)와 보조밸브(20)가 차단막(30) 상으로 안착되면 정수배관(102)을 차단하게 되어 펌프 내부로 실링수(실링수가 유동 혹은 충전된 부위는 점으로 표시되어 있음, 도 3)를 공급하지 못한다.In addition, the main valve 10 and the auxiliary valve 20 of the sealing water supply valve 1 includes a blocking film 30 arranged across the inside of the purified water pipe 102 so as to open and close the purified water pipe 102. The central portion of the barrier film 30 is perforated to allow the main valve 10 and the auxiliary valve 20 to be seated. When the main valve 10 or the auxiliary valve 20 is separated from the blocking membrane 30, the sealing water of the purified water pipe 102 may flow into the pump through the perforation part 31 (see FIG. 3), and the main valve 10 and When the auxiliary valve 20 is seated on the blocking membrane 30, the water purification pipe 102 is blocked, and thus the sealing water (the portion where the sealing water is flowed or filled is indicated by a dot, FIG. 3) cannot be supplied into the pump. .

보조밸브(20)는 펌프를 구동하기 전에 휴지 상태에서 펌프 내부로 실링수를 공급하기 위해 설치된 것으로, 보조밸브(20)의 개방은 전원을 통한 전자력을 이용한다. 기술되었듯이, 솔레노이드(21)는 전자력을 통해 보조밸브(20)의 개방 및 폐쇄를 돕는데, 이를 위해서 솔레노이드(21)는 주밸브(10)와 반대쪽, 바람직하게는 수압배관(101)의 반대쪽에 위치된다.The auxiliary valve 20 is installed to supply the sealing water into the pump in the idle state before driving the pump, the opening of the auxiliary valve 20 uses the electromagnetic force through the power source. As described, the solenoid 21 assists in opening and closing the auxiliary valve 20 via electromagnetic force, for which the solenoid 21 is located opposite the main valve 10, preferably opposite the hydraulic piping 101. do.

솔레노이드(21)는 보조밸브(20)와 피스톤(22), 제2스프링(23) 및, 전원 부(24)로 이루어진다. 피스톤(22)과 전원부(24)는 전자력 발생을 돕는 소재(코일, 자석)로 만들어지는 것이 바람직하다. 예컨대, 전원부(24)를 통해 전원이 공급되면, 피스톤(22)과 전원부(24) 사이에 전자력이 발생하여 피스톤(22)이 전원부(24)로 밀착된다. 이로 인해서, 피스톤(22)의 상단부에 연결된 보조밸브(20)가 주밸브(10)로부터 떨어지게 된다. The solenoid 21 includes an auxiliary valve 20, a piston 22, a second spring 23, and a power supply unit 24. The piston 22 and the power supply unit 24 are preferably made of a material (coil, magnet) to help generate electromagnetic force. For example, when power is supplied through the power supply unit 24, electromagnetic force is generated between the piston 22 and the power supply unit 24 so that the piston 22 is in close contact with the power supply unit 24. As a result, the auxiliary valve 20 connected to the upper end of the piston 22 is separated from the main valve 10.

보조밸브(20)가 주밸브(10)에서 떨어지게 되면, 주밸브(10) 중심에 보조밸브(20)를 수용한 구멍을 통해 실링수가 펌프로 공급될 수 있다.When the auxiliary valve 20 is separated from the main valve 10, the sealing water may be supplied to the pump through a hole in which the auxiliary valve 20 is accommodated in the center of the main valve 10.

솔레노이드(21)에 전원이 차단되면, 피스톤(22)과 전원부(24) 사이에 전자력이 제거된다. 그런 다음에 피스톤(22) 둘레를 감싸고 있던 제2스프링(23)을 매개로 하여 피스톤(22)은 원위치로 복귀되면서 보조밸브(20) 또한 피스톤(22)의 이동에 따라 주밸브(10)를 향해 이동한다.When the power supply to the solenoid 21 is cut off, the electromagnetic force is removed between the piston 22 and the power supply unit 24. Then, the piston 22 is returned to its original position through the second spring 23 that surrounds the piston 22, and the auxiliary valve 20 also moves toward the main valve 10 as the piston 22 moves. Move.

주밸브(10)의 개폐를 돕는, 실린더(11)가 주밸브(10)와 피스톤(12) 및 제1스프링(13)으로 구성된다.The cylinder 11, which assists the opening and closing of the main valve 10, consists of the main valve 10, the piston 12, and the first spring 13.

실린더(11)는 수압배관(101)과 정수배관(102)의 교차점에 위치되는 것이 바람직하며, 특히 주밸브(10)는 실린더(11)의 피스톤(12) 상단부에서 뻗어 나와 차단막(30)에 안착되어 있다. Cylinder 11 is preferably located at the intersection of the hydraulic pipe 101 and the water purification pipe 102, in particular the main valve 10 extends from the upper end of the piston 12 of the cylinder 11 and seated on the blocking film 30 It is.

도면에 도시된 바와 같이, 주밸브(10)가 차단막(30)을 관통하지 못하도록 주밸브(10)와 차단막(30)의 접합부위를 경사지게 배열하되, 주밸브(10)의 안착과 이탈을 돕기 위해 차단막(30)의 천공부(31)는 안쪽으로 테이퍼져 있는 형상으로 되어 있다. 이러한 천공부(31)의 형태에 맞춰 주밸브(10)의 가장자리를 대응형상으로 유 지토록 한다. 덧붙여서, 주밸브(10)로부터 보조밸브(20)의 안착과 이탈을 돕기 위해, 주밸브(10)와 천공부(31)의 형태와 유사하게 주밸브(10)의 중심은 안쪽으로 테이퍼져 있고 이와 대응하는 형상으로 보조밸브(20)의 가장자리를 형성한다. 바람직하기로, 주밸브(10)는 중심부가 뚫려있으며, 그 중심부는 안쪽으로 테이퍼져 있는 한편, 그 가장자리도 경사져 있어 마름모꼴형상으로 될 수 있다.As shown in the figure, the main valve 10 is arranged to be inclined at the junction of the main valve 10 and the blocking membrane 30 so as not to penetrate the blocking membrane 30, the blocking membrane (to help the seating and detachment of the main valve 10) The perforations 31 of 30 are tapered inwardly. Maintaining the edge of the main valve 10 in a corresponding shape in accordance with the shape of the perforated portion 31. In addition, similar to the shape of the main valve 10 and the perforations 31, the center of the main valve 10 is tapered inward and correspondingly to assist in the installation and detachment of the auxiliary valve 20 from the main valve 10. To form the edge of the auxiliary valve 20. Preferably, the main valve 10 is perforated in the center, the center of which is tapered inwards, while the edge thereof is also inclined, so that the main valve 10 may be rhombic.

펌프(100;도 1 참조)에 실링수가 완충된 후에 펌프를 가동하면, 수압배관(101)을 따라 유체(수돗물)가 이동하면서 실린더(11)의 피스톤(12)를 가압하게 되고 이 외력으로 주밸브(10)는 차단막(30)의 천공부(31)로부터 이탈되게 된다. 그런 다음에, 천공부(31)는 정수배관(102)에 있던 실링수를 원활하게 공급하기 위해 완전개방된다.When the pump is operated after the sealing water is buffered in the pump 100 (see FIG. 1), the fluid (tap water) moves along the hydraulic pipe 101 to pressurize the piston 12 of the cylinder 11, and the main valve is driven by the external force. 10 is separated from the perforations 31 of the blocking film 30. Then, the perforation part 31 is completely opened in order to supply the sealing water which was in the purified water pipe 102 smoothly.

펌프가 휴지되면, 수압배관(101)에 유체가 공급되지 않게 되므로 실린더(11)의 피스톤(12)은 제1스프링(13)을 수단으로 하여 원위치되면서 피스톤(12) 상단부에 고정된 주밸브(10)는 천공부(31)를 향해 이동하여 차단막(30)을 폐쇄하여 정수배관(102)의 실링수를 펌프 내부로 이동하지 못하게 한다.When the pump is stopped, the fluid is not supplied to the hydraulic pipe 101, so the piston 12 of the cylinder 11 is returned to its original position by means of the first spring 13 and the main valve 10 fixed to the upper end of the piston 12. ) Moves toward the perforation 31 to close the blocking membrane 30 to prevent the sealing water of the purified water pipe 102 from moving inside the pump.

도 3은 본 발명에 따른 펌프의 실링수 공급밸브의 작동순서도를 도해한 것이다. 도 2에 설명된 각 구성부재들의 작동순서를 각 단계별로 설명한다.Figure 3 illustrates the operation flowchart of the sealing water supply valve of the pump according to the present invention. The operation sequence of each of the components described in FIG. 2 will be described in each step.

도 3(a)는 펌프(도 1 참조)가 휴지상태에 있을 때를 도시한 것으로, 도시된 바와 같이 정수배관(102)은 차단막(30)과 그 중심부를 주밸브(10) 및 보조밸브(20)로써 폐쇄되어 실링수를 펌프로 유입시키지 못하도록 되어 있다.3 (a) shows when the pump (see FIG. 1) is at rest. As shown in FIG. 3, the purified water pipe 102 has a main membrane 10 and an auxiliary valve 20 connected to the blocking membrane 30 and the center thereof. It is closed to prevent the sealing water from flowing into the pump.

펌프를 가동하기 전에, 본 발명에 따른 실링수 공급밸브(1)의 보조밸브를 개 방하는 단계를 포함하되, 도 3(b)에 도시된 바와 같이 전원이 솔레노이드(21)의 전원부(24)에 전원을 공급하면 전원부(24)와 피스톤(22) 사이에 전자력이 발생하여 피스톤(22)을 전원부(24) 쪽으로 잡아당겨 피스톤(22)에 부착된 보조밸브(20)를 차단막(30)에 안착된 주밸브(10)로부터 이격시킨다. 이러한 공정을 통해, 주밸브(10)의 중심구멍을 통해 정수배관(102)의 유체(또는 실링수)가 펌프 내부로 유입될 수 있게 된다.Before starting the pump, including the step of opening the auxiliary valve of the sealing water supply valve 1 according to the present invention, the power source 24 of the solenoid 21 as shown in Figure 3 (b) When the electric power is supplied to the power supply unit 24, the electromagnetic force is generated between the power supply unit 24 and the piston 22, and the piston 22 is pulled toward the power supply unit 24 so that the auxiliary valve 20 attached to the piston 22 is connected to the blocking film 30. Spaced from the seated main valve (10). Through this process, the fluid (or sealing water) of the purified water pipe 102 may be introduced into the pump through the center hole of the main valve 10.

도 3(c)를 참조하면, 전술된 공정을 통해 펌프 내부가 실링수로 만수되면, 펌프(100;도 1 참조), 예컨대 취수펌프가 기동되면서 펌프 케이싱 내부에서 수압이 형성되면서 수압배관(101)을 따라 유체가 공급되면서 실린더(11)의 하부, 더욱 구체적으로 피스톤(12)을 밀어붙인다. 피스톤(12)이 밀쳐지면서 피스톤(12) 상부에 연결된 주밸브(10)는 차단막(30)으로부터 이미 이격된 보조밸브(20)를 향해 이동한다. 이러한 상황이 유지되므로, 보조밸브(20)의 개방을 위한 전자력이 더 이상 필요하지 않게 되므로, 솔레노이드(21)의 전원부(24)에 공급되었던 전원을 차단할 수 있다. 전원이 차단되어도, 수압으로 밀어붙여진 주밸브(10)가 보조밸브(20)를 지지할 수 있어 차단막(30)의 천공부(31)는 계속 개방상태로 놓이게 된다.Referring to FIG. 3 (c), when the inside of the pump is filled with the sealing water through the above-described process, the pump 100 (see FIG. 1), for example, the water intake pump is started while the water pressure is formed inside the pump casing. As the fluid is supplied along the bottom of the cylinder 11, more specifically, the piston 12 is pushed. As the piston 12 is pushed, the main valve 10 connected to the upper portion of the piston 12 moves toward the auxiliary valve 20 which is already separated from the blocking film 30. Since such a situation is maintained, since the electromagnetic force for opening the auxiliary valve 20 is no longer needed, power that has been supplied to the power supply unit 24 of the solenoid 21 can be cut off. Even when the power is cut off, the main valve 10 pushed by the hydraulic pressure can support the auxiliary valve 20 so that the perforated portion 31 of the cutoff membrane 30 is kept open.

펌프가 정지되면, 더 이상 수압배관(101)으로 수압이 발생하지 않게 되어 주밸브(10)를 가압할 수 없어 도 3(d)에 도시된 바와 같이 제1스프링(13)의 복원력으로 피스톤(12)을 원위치로 이동시켜 주밸브(10)는 최초 천공부(31)로 이동하게 되는 동시에, 보조밸브(20)도 전기력이 이미 제거되어 있어 제2스프링(23)의 복원력으로 주밸브(10)를 가압하게 된다. 이와 같이, 제2스프링(23)에 의해 보조밸브(20) 가 주밸브(10)를 더욱 확실하게 천공부(31)에 밀착시켜 실링수의 누수가 일어나지 않게 된다.When the pump is stopped, the hydraulic pressure is no longer generated in the hydraulic pressure pipe 101, so that the main valve 10 cannot be pressurized, and as shown in FIG. 3 (d), the piston 12 is restored by the restoring force of the first spring 13. ), The main valve 10 is moved to the first hole 31 at the same time, and the auxiliary valve 20 is already removed from the electric force to pressurize the main valve 10 by the restoring force of the second spring 23. Done. In this way, the auxiliary valve 20 makes the main valve 10 adhere to the perforation part 31 more reliably by the second spring 23, so that leakage of the sealing water does not occur.
