Description
본 고안은 흡기용 체크밸브와 배기용 체크밸브를 일체로 구성한 것을 기압급수설비의 보기탱크 등에 설치하여 사용되는 단일체로된 흡 배기용 체크밸브에 관한 것이다.The present invention relates to a monolithic intake and exhaust check valve that is used by installing an intake check valve and an exhaust check valve integrally with a bogie tank of a pneumatic water supply facility.
종래의 일반적인 기압설비는 보기탱크 상부에 흡기와 배기용 두종류의 체크밸브를 각각 설치하므로서 그 설치가 복잡해질 뿐 아니라 보기탱크의 흡입과정 중 흡기밸브를 통하여 외부공기를 흡입하는 과정 중 다시 배기밸브를 통하여 공기와 물을 기압수조에 공급하여 공기와 물을 보충하게 되어 있다.Conventional air pressure equipment is equipped with two types of check valves for intake and exhaust, respectively, on the upper part of the bogie tank, which not only makes the installation complicated, but also exhausts the valve during the intake of outside air through the intake valve during the intake process of the bogie tank. The air and water are supplied to the pressure tank through the air and water to supplement.
이와 같은 방안은 맨 먼저 위 체크밸브의 높은 정밀도와 높은 밀봉성, 그리고 신뢰성이 요구된다. 만약 그렇지 않으면 보기(補氣)효율에 중대한 영향을 끼쳐 그 효력이 없어지기까지 한다. 그러치만 현재 위와 같은 요구에 부합하여 통용되는 체크밸브를 제작하기에는 매우 힘들다.This approach first requires high precision, high sealability and reliability of the top check valve. Otherwise, it will have a significant impact on viewing efficiency and even lose its effectiveness. However, it is very difficult to manufacture a check valve that is commonly used to meet the above requirements.
그 다음 배기밸브를 거쳐 공기와 물을 보충하는 방안은 수격작용, 물때와 물의 부폐가 발생하기 쉬워 밸브의 수명을 단축시키는 문제점이 있었다.Then, the method of replenishing air and water through the exhaust valve has a problem of shortening the life of the valve is easy to occur water hammer, scale and water.
본 고안은 종래의 여러가지 문제점들을 해결하기 위하여 흡기용 체크밸브와 배기용 체크밸브를 조합시켜 일체화시킨 단일체로된 흡 배기용 체크밸브를 구성하여 기압수조의 상부에 수평으로 설치하고, 아크릴관을 이용하여 수직으로 기압수조 하부의 분사식 보기탱크까지 직접 연결시키게 되면 보기효율이 높아지고 수격작용, 물때와 물의 부폐현상을 방지할 수 있어 그 수명을 연장시키는 동시에 기압수조의 수위 지시장치 등을 없앨 수 있다.In order to solve various problems in the related art, the present invention constitutes a unitary intake and exhaust check valve integrated by combining an intake check valve and an exhaust check valve, and is installed horizontally on an upper portion of the pneumatic water tank, using an acrylic tube. By connecting directly to the spray bogie tank in the lower part of the pneumatic tank vertically, the bogie efficiency is increased and water hammering action can be prevented, which can prevent the decay of scale and water, thereby prolonging its life and eliminating the water level indicator of the pneumatic water tank.

Is formed, the right pipe connector (b) is connected to the upper pressure tank in the horizontal direction through the welding connector (13). Then, the acrylic plate (YB) is inserted into the lower end connector (c) and fixed by using the connection nut 16 to be sealed, and then connected to the injection viewing tank (PBQ) below the air pressure tank (QS) in the sealing direction.
본체(1)에 형성된 흡기실(A)내에 흡기밸브의 덮개(2)와 스프링(3), 흡기개폐문(4)을 차례로 설치한 다음 흡기밸브덮개(2) 상부의 중심구멍(6a) 상부에 형성된 수개의 공기 흡입구(a)의 내측에 필터(7)를 설치하고, 캡(8)을 덮어 흡기부분을 구성하였다. 여기에 흡기개폐문(4)의 상단은 고무 0-링(5)을 씌운 원추형 개폐문이 되고 그 하단 안내봉(4a)은 흡기밸브 덮개(2)의 중심구멍(2a)에 삽입하여 상하로 움직이게하며, 스프링(3)의 약간 탄성(대략 개폐문자체의 무게보다는 그 탄력이 크다.)에 의해 위로 닫힌 상태가 된다.In the intake chamber (A) formed in the main body (1), the cover (2) of the intake valve, the spring (3), and the intake opening / closing door (4) are installed in this order, and then in the upper part of the center hole (6a) above the intake valve cover (2). The filter 7 was provided inside the several formed air intake openings a, and the cap 8 was covered and the intake part was comprised. Here, the upper end of the intake opening / closing door 4 becomes a conical opening door covered with a rubber 0-ring 5, and the lower guide rod 4a is inserted into the center hole 2a of the intake valve cover 2 to move up and down. , The spring 3 is closed up slightly by elasticity (approximately more elastic than the weight of the opening and closing character).
그리고 본체(1)의 배기실(B)내에는 칼날형 밸브시이트(14)와 배기개폐문(11)을 설치한 다음 배기실(B) 상부 암나사구멍(B1)에 배기 밸브덮개(10)를 나사조립시켜 배기부분을 구성하였다. 여기에서 배기개폐문(11)의 하부는 보울트(15)를 이용해 고정시킨 고무패킹(12)이 설치되어 있고 상기 안내봉(11a)의 양측에는 2개의 통기홈(11b)이 있으며, 이 안내봉(11a)을 배기 밸브덮개(10)의 중심공(10a)에 삽입시켜 상하로 움직이게 하며, 평상시에는 배기개폐문(11)의 무게에 의해 칼날형 밸브시이트(14)를 아래로 닫는다. 그리고 밸브덮개(10)의 중심구멍(10a) 상부 암나사부에 보울트(9)를 나사조립시켜 상부에서의 기체 유실을 방지한다. 여기에서 이 보울트(9)대신에 전기접점 압력계(도면에 도시되지 않았음)를 설치하면 기압수조(QS)의 압력을 뚜렷이 볼 수 있어, 압력을 제어할 수 있으며, 이곳에 스로틀밸브 도면에 도시되지 않았음)를 설치하면 스로틀밸브를 통하여 기압수조(QS)에 공기를 채우거나 방출작용을 할 수 있다.Then, the blade valve seat 14 and the exhaust opening and closing door 11 are installed in the exhaust chamber B of the main body 1, and then the exhaust valve cover 10 is screwed into the upper female threaded hole B1 of the exhaust chamber B.

If not installed, the air can be filled or discharged through the throttle valve to the air pressure tank (QS).
다음은 도 3와 결합하여 본 고안의 작동을 설명하면 다음과 같다.Next, the operation of the present invention in combination with FIG. 3 will be described.
급수펌프(P)가 기동하여 급수하는 기간에는 전기가 통하여 솔레노이드밸브(DF)를 오픈(OPEN)시키고 기압수조(QS) 하부의 버터플라이밸브(D)부터 여과기(GL)사이 T자관 내의 압력수는 분사보기탱크(PBG)를 통하여 솔레노이드밸브(DF)를 향하여 분사하고 이 분사보기탱크(PBG)내의 물을 흡수하여 함께 저수조 상부까지 회류한다. 그래서 아크릴관(YB)과 단일체로된 흡 배기용 체크밸브(호흡밸브)(HX)내에는 진공이 발생하고 외부공기는 단일체로된 흡 배기용 체크밸브(HX)의 공기 흡입구(a)를 거쳐 흡기개폐문(4)를 열어 흡기실(A), 및 배기실(B) 실까지 흡수되고 다시연결관(c)과 아크릴판(YB)를 거쳐 분사보기탱크(PBG)에 가득차게 된다.During the period when the water feed pump (P) starts and feeds water, the solenoid valve (DF) is opened through electricity, and the pressure water in the T tube between the butterfly valve (D) and the filter (GL) in the lower part of the pressure water tank (QS) is opened. Is sprayed toward the solenoid valve (DF) through the injection viewing tank (PBG) and absorbs the water in the injection viewing tank (PBG) and flows back together to the top of the reservoir. Therefore, a vacuum is generated in the acrylic tube (YB) and the intake / exhaust check valve (breathing valve) (HX) in one unit, and the external air passes through the air inlet (a) of the intake / exhaust check valve (HX) in one unit. The intake opening / closing door 4 is opened to be absorbed to the intake chamber A and the exhaust chamber B, and filled in the injection viewing tank PBG via the connecting pipe c and the acrylic plate YB.
이러한 흡수과정 중 기압수조(QS)의 상부 기압은 완전하게 배기개폐문(11)을 닫음에 따라 분사보기탱크(PBQ)내의 압축공기가 역류하는 것을 방지한다.The upper air pressure of the air pressure tank QS during the absorption process prevents backflow of the compressed air in the injection viewing tank PBQ as the exhaust opening and closing door 11 is completely closed.
만약 그렇지 않으면 분사보기탱크(PBQ)의 흡기량에 중대한 영향을 미친다.If not, it has a significant influence on the air intake amount of the PBQ.
여기에서 전기가 끊어져 솔레노이드밸브(DF)가 닫치면 분사보기탱크(PBQ)에 물이 유입되어 그 내부에 흡입된 공기를 압축하여 압력이 기압수조(QS) 상부 압력까지 상승할 때 배기개폐문(11)을 열어 가압수조(QS)를 압박하여 공기를 보충하고 아크릴관(YB)내 수위가 기압수조(QS) 수위와 같아지면 상승을 멈춘다.When the solenoid valve (DF) closes when the electricity is cut off, water flows into the injection viewing tank (PBQ) and compresses the air sucked into the exhaust bore (11) when the pressure rises to the upper pressure of the pressure tank (QS). ), Pressurize the pressurized water tank (QS) to replenish the air, and stop rising when the water level in the acrylic tube (YB) is equal to the air pressure tank (QS) water level.
이러한 보기(補氣)과정 중 흡입개폐문(4)은 시종 닫힘상에 있어 분사보기탱크(PBQ) 내의 공기가 외부로 누출되는 것을 방지한다.The suction opening and closing door 4 during the bogie process prevents the air in the injection bogie tank PBQ from leaking out.
만약 그렇지 않으면 보기량에 영향을 미친다.If not, it affects the view volume.
종합적으로 상술한 본 고안은 아래와 같은 기술적인 효과를 가지고 있다.The present invention described above comprehensively has the following technical effects.
1. 고무 0-링(5)을 씌운 60도의 원추형 흡기개폐문(4)과 고무패킹(12)을 설치하고 있는 배기개폐문(11)은 각각 그 밸브시트(6)(14)를 닫고, 이러한 방안을 채택하여 개폐문의 정밀도, 밀봉성과 신뢰성을 대대적으로 높였다.1. The 60 degree conical intake opening and closing door 4 with rubber 0-ring 5 and the exhaust opening and closing door 11 with rubber packing 12 close their valve seats 6 and 14, respectively. It greatly improves the precision, sealing and reliability of the door.
이와 같이 구성된 본고안은 수 십만번의 무수한 개폐과정을 거쳐도 매우 높은 기체 밀봉성을 유지할 수 있고 보기효율 용적은 95% 이상까지 된다.In this way, this proposal can maintain a very high gas sealability after hundreds of thousands of opening and closing processes, and the viewing efficiency volume is more than 95%.
2. 단일체로된 흡 배기용 체크밸브(호흡밸브)(HX)를 기압수조(QS)의 상부까지 수평으로 설치하므로서 거의 물과 접촉이 없기 때문에 수격작용, 물 때 및 물의 부패 등의 현상이 발생하지 않아 단일체로된 흡 배기용 체크밸브(호흡밸브)(HX)의 사용 수명을 대폭적으로 연장 시켰다.2. Since a single intake and exhaust check valve (breathing valve) (HX) is installed horizontally up to the top of the pressure water tank (QS), there is almost no contact with water, causing water hammering, water and water decay. As a result, the service life of the unitary intake and exhaust check valve (breathing valve) (HX) has been greatly extended.
3. 종래의 흡기개폐문(4)은 물론이고 배기개폐문(11)은 비록 그 역지 밀봉성이 높으나 기체 흐름의 순향 밀봉성이 거의 없다. 그래서 이 단일체로된 흡 배기용 체크밸브(호흡밸브)(HX)를 채택하면 아래와 같은 두가지의 효과가 발생한다.3. The exhaust opening and closing door 11, as well as the conventional intake opening and closing door 4, have high reverse sealing properties but little forward sealing of gas flow. Therefore, when this unit is adopted as a single intake and exhaust check valve (breathing valve) (HX), the following two effects occur.
1) 기압수조(QS) 압력과 급수펌프(P)의 출구압력이 완전히 평형상태에 있을 때에도 계속적으로 상술한 보기과정을 실시하여 이 두 개 압력차에 어떠한 제한도 받지 않는다.1) Even when the pressure of the water pressure tank (QS) and the outlet pressure of the water supply pump (P) are completely at equilibrium, the above-described examples are continuously carried out so that there are no restrictions on the two pressure differences.
2) 공기보충이 정지할 때, 아크릴관(YB) 내에 상승한 최고 수위는 기압수조(QS)수위와 같고 이관은 기압수조(QS)의 수위지시기와 같은 역할을 하기 때문에 별도의 전용 수위지시계를 설치할 필요가 없다.2) When the air replenishment stops, the highest water level raised in the acrylic tube (YB) is the same as the water tank (QS) level, and this pipe acts as the water level indicator of the water tank (QS). no need.
3) 배기개폐문(11)의 안내봉(11a)의 양측에 형성된 통기홈(11b)에 의하여 이 배기개폐문(11)의 정밀도를 높일 뿐만 아니라 보울트(9)을 설치한 곳에 전기접점 압력계를 설치하면 기압수조(QS)의 기압을 뚜렷이 볼 수 있어 제어할 수도 있으며, 스로틀밸브를 설치하면 이 밸브를 통하여 기압수조(QS)에 공기를 채우거나 방출할 수 있다.3) The ventilation openings 11b formed on both sides of the guide rod 11a of the exhaust opening and closing door 11 not only increase the accuracy of the exhaust opening and closing door 11, but also install an electric contact pressure gauge at the place where the bolt 9 is installed. The pressure of the water pressure tank (QS) can be clearly seen and controlled. If a throttle valve is installed, the air can be filled or discharged through the water pressure tank (QS).
위의 상황을 종합해 보면 본 고안은 정밀성이 있고 밀봉성이 높으며, 기압수조(QS) 상부와 수평으로 설치하여 수격작용, 물때와 물의 부폐 현상을 방지하며, 이로 인하여 사용수명을 연장시켰으며, 그 하부의 아크릴관(YB)은 기압수조(QS)의 수위 지시기의 역할을 하는 등의 장점이 있어 모든 중력보기방식에 통용될 수 있다.In summary, the present invention has high precision and high sealability, and is installed horizontally with the upper part of the air pressure tank (QS) to prevent water hammer, scale and water decay, thereby extending the service life. The lower acrylic tube (YB) has the advantage of acting as a water level indicator of the water pressure tank (QS), and can be used in all gravity viewing methods.
