Description
본 고안은 유체 이송용 배관라인에 설치되어 1차측으로 부터 소정압력으로 공급되는 유체를 요구되는 압력으로 감압시킨후 2차측으로 방출하는 감압밸브에 관한 것으로, 더욱 상세하게는 감압밸브를 구성하는 메인방향밸브에 장착되는 감압 파일럿(Pilot)밸브의 일측에 형성된 공기유통구멍에 공기유통관의 하단부를 결합하고 상단부는 침수수위보다 높은 곳에 위치되도록 수직으로 길게 연결설치하여서, 침수시에도 공기유통관을 통해 감압파일럿밸브내부로 물이 침투하지 못하도록 함으로써, 감압파일럿밸브내부에 구비되는 압력조절용 스프링이 녹슬거나 부식되는 것을 완벽하게 방지하여 셋팅된 압력이 전혀 변동됨이 없도록 함은 물론 사용수명을 장구하게 하여 유지,보수가 편리하도록 한 감압밸브에 관한 것이다.The present invention relates to a pressure reducing valve installed in a fluid transfer pipe line for decompressing a fluid supplied from a primary side at a predetermined pressure to a required pressure and then discharging it to a secondary side. The lower end of the air distribution pipe is coupled to the air flow hole formed on one side of the pressure reducing pilot valve mounted on the directional valve, and the upper end is vertically connected so as to be positioned above the flooding level. By preventing water from penetrating into the pilot valve, the pressure regulating spring provided inside the pressure reducing pilot valve is completely prevented from rusting or corroding, so that the set pressure is not changed at all and the service life is maintained. The present invention relates to a pressure reducing valve for easy maintenance.
일반적으로 유체 이송용 배관라인에 설치되는 감압밸브는 첨부도면 도1에 도시된 바와같이 배관라인(1)에 직접설치되는 다이아프램(Diaphragm)식 메인방향밸브(10)와,In general, the pressure reducing valve installed in the fluid transfer pipe line includes a diaphragm type main directional valve 10 installed directly on the pipe line 1 as shown in FIG.
상기 메인방향밸브(10)에 장착되며 조절압력범위에 따라 압력조절볼트(21)의 작동에 의해 압축되는 스프링(22)의 압력에 의해 2차 압력을 조절하는 역시 다이아프램식 감압파일럿(Pilot)밸브(20)와,The diaphragm pressure reducing pilot (Pilot) is also mounted on the main directional valve 10 and controls the secondary pressure by the pressure of the spring 22 compressed by the operation of the pressure adjusting bolt 21 according to the adjustment pressure range. With the valve 20,
상기 메인방향밸브(10)에 감압파일럿밸브(20)를 다양한 방법으로 연결설치하며 개폐속도를 조절하는 닫침속도(Close Speed)콘트롤밸브(31) 및 열림속도(OpenSpeed)콘트롤밸브(32)로 이루어져,The pressure reducing pilot valve 20 is installed and connected to the main direction valve 10 in various ways, and is composed of a close speed control valve 31 and an open speed control valve 32 to control the opening and closing speed. ,
2차측압력을 조절할때에는 출구측밸브(3)를 닫고 입구측밸브(2)를 열어둔 상태에서 감압파일럿밸브(20)의 캡(Cap)(25)을 열고 로크너트(Lock Nut)(24)를 푼다음 2차측압력계(5)를 보면서 압력조절볼트(21)를 좌측 또는 우측방향으로 돌려서 스프링(22)을 가압함으로써 압력을 조절하도록 구성된다.When adjusting the secondary pressure, open the cap (25) of the pressure reducing pilot valve (20) with the outlet valve (3) closed and the inlet valve (2) open, and lock nut (24). The pressure is adjusted by pressing the spring 22 by turning the pressure adjusting bolt 21 in the left or right direction while releasing the pressure gauge while watching the secondary pressure gauge 5.
이와같은 감압밸브(100)는 셋팅(Setting)하여 두면 자동으로 작동하여 수위조절, 감압, 릴리이프, 차압유지 기능을 하게 되는 것이다.Such a pressure reducing valve 100 is set (Setting) to automatically operate to maintain the water level control, pressure reduction, relief, differential pressure.
미설명 부호 (4)는 1차측압력계이다.Reference numeral 4 is a primary pressure gauge.
그런데 이와같은 종래의 감압밸브(100)는 상기 감압파일럿밸브(20)의 측면에 공기유통구멍(20a)이 대기와 접촉되도록 일체로 형성되어있는바,However, such a conventional pressure reducing valve 100 is integrally formed such that the air flow hole 20a is in contact with the atmosphere on the side of the pressure reducing pilot valve 20.
이는 반드시 물과 접촉이 되지 않도록 하여야 하는데 그 이유는 상기 공기유통구멍(20a)을 통해 물이 들어갈 경우에는 2차측압력을 셋팅하는데 사용되는 스프링(22)이 녹슬거나 부식되어 셋팅된 압력이 변동됨으로써 오동작이 일어나거나 감압밸브(100)로서의 제기능을 못하게 되는 것은 물론이고 이로인해 관내의 이상압력으로 인한 워터햄머의 발생은 물론 배관을 파손하고 또한 감압밸브(100) 출구쪽 기계의 수명을 단축시키는 등 밸브차체는 물론 이와 연관된 배관 및 주변기계 전체의 사용수명을 현저하게 단축시키게 되기 때문이다.This must be done so that it does not come into contact with water because the spring 22 used to set the secondary pressure when the water enters through the air flow hole 20a is rusted or corroded and the set pressure is changed. This will not only cause malfunctions or impair the proper function as the pressure reducing valve 100, but also cause water hammers due to abnormal pressure in the pipes, as well as damage the piping and shorten the life of the machine at the outlet of the pressure reducing valve 100. This is because the service life of the valve body as well as the pipes and peripherals associated with it are significantly reduced.
따라서, 종래의 감압밸브(100)는 셋팅압력을 유지하는지 수시로 점검을 하여야 하므로 유지,보수 또한 매우 힘이 드는 등의 여러가지 문제점이 발생하였다.Therefore, the conventional pressure reducing valve 100 has to be checked from time to time to maintain the set pressure, so a variety of problems, such as maintenance, maintenance is also very difficult.
본 고안은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 메인방향밸브에 장착되는 감압 파일럿(Pilot)밸브의 일측에 형성된 공기유통구멍에 공기유통관의 하단부를 결합하고 상단부는 침수수위보다 높은 곳에 위치되도록 수직으로 길게 연결설치하여서, 침수시에도 공기유통관을 통해 감압파일럿밸브내부로 물이 침투하지 못하도록 함으로써,The present invention has been made in view of the above-mentioned conventional problems, the lower end of the air flow pipe coupled to the air flow hole formed on one side of the pressure reducing pilot (Pilot) valve mounted to the main directional valve and the upper end is higher than the submerged water level It is installed vertically long so as to be located in the place, and prevents water from penetrating into the decompression pilot valve through the air distribution pipe even when flooded,
침수시에도 공기유통관을 통해 감압 파일럿밸브내부로 물이 침투하지 못하도록 구성한 고품질 고품격의 감압밸브를 제공함으로써, 감압 파일럿밸브내부에 구비되는 압력조절용 스프링이 녹슬거나 부식되는 것을 완벽하게 방지하여 셋팅된 압력이 전혀 변동됨이 없도록 함은 물론 사용수명을 장구하게 하여 유지,보수가 편리하도록 함에 그 목적을 둔 것이다.By providing a high-quality high-quality pressure reducing valve configured to prevent water from penetrating into the pressure-reducing pilot valve through an air distribution pipe even when flooding, the pressure set by completely preventing the pressure regulating spring provided inside the pressure-reducing pilot valve from rusting or corrosion. Its purpose is to make sure that there is no change at all, as well as to make the service life long and convenient for maintenance.

상기와 같은 목적을 달성하기 위한 본 고안은 첨부도면 도2 내지 도3b에 도시된 바와같이 배관라인(1)에 직접설치되는 다이아프램(Diaphragm)식 메인방향밸브(10)와,The present invention for achieving the above object is a diaphragm (Diaphragm) type main directional valve 10 is installed directly on the piping line (1), as shown in the accompanying drawings 2 to 3b,
상기 메인방향밸브(10)에 장착되며 조절압력범위에 따라 압력조절볼트(21)의 작동에 의해 압축되는 스프링(22)의 압력에 의해 2차 압력을 조절하는 역시 다이아프램식 감압파일럿(Pilot)밸브(20)와,The diaphragm pressure reducing pilot (Pilot) is also mounted on the main directional valve 10 and controls the secondary pressure by the pressure of the spring 22 compressed by the operation of the pressure adjusting bolt 21 according to the adjustment pressure range. With the valve 20,
상기 메인방향밸브(10)에 감압파일럿밸브(20)를 다양한 방법으로 연결설치하며 개폐속도를 조절하는 닫침속도(Close Speed)콘트롤밸브(31) 및 열림속도(Open Speed)콘트롤밸브(32)로 이루어져, 1차측으로 부터 소정압력으로 공급되는 유체를요구되는 압력으로 감압시킨후 2차측으로 방출하는 감압밸브(100)에 있어서,The pressure reducing pilot valve 20 is installed and connected to the main direction valve 10 in various ways, and a closing speed control valve 31 and an open speed control valve 32 for adjusting the opening and closing speed. In the pressure-reducing valve 100 for reducing the fluid supplied from the primary side at a predetermined pressure to the required pressure and then discharged to the secondary side,
상기 메인방향밸브(10)에 장착되는 감압파일럿밸브(20)의 일측에 형성된 공기유통구멍(20a)에 공기유통관(300)의 하단부를 결합하고 상단부는 침수수위보다 높은 곳에 위치되도록 수직으로 길게 연결설치하여서, 침수시에도 공기유통관(300)을 통해 감압파일럿밸브(20) 내부로 물이 침투하지 못하도록 구성한 것이다.The lower end of the air distribution pipe 300 is coupled to the air flow hole 20a formed at one side of the pressure reducing pilot valve 20 mounted on the main direction valve 10, and the upper end is vertically connected to be located at a position higher than the submerged water level. By installing it, it is configured to prevent water from penetrating into the decompression pilot valve 20 through the air distribution pipe 300 even during immersion.
여기서, 상기 감압파일럿밸브(20)의 일측에 형성된 공기유통구멍(20a)에 공기유통관(300)을 일체형으로 결합하는 방법은 여러가지가 있으나 첨부도면 도3a와 같이 상기 공기유통구멍(20a)내연에 나사부(40)를 형성하여 나사부(40)에 연결구(50)를 나사결합한다음 연결구(50)에 공기유통관(300)을 결합하여서 연결토록 구성하거나 또는 첨부도면 도3b와 같이 상기 공기유통구멍(20a)이 구비되는 연결부(200)를 길게 돌출형성하고 이 연결부(200)에 공기유통관(300)를 결합하여서 연결토록 구성하는 것이 가장 바람직하다.Here, there are various methods of integrally coupling the air flow pipe 300 to the air flow hole 20a formed at one side of the pressure reducing pilot valve 20, but as shown in FIG. Form the threaded portion 40 to screw the connector 50 to the threaded portion 40, and then configured to connect by connecting the air flow pipe 300 to the connector 50, or as shown in Figure 3b attached to the air distribution hole 20a It is most preferable to form the connecting portion 200 is provided to protrude long and to connect the air flow pipe 300 to the connecting portion 200 to be connected.
본 고안은 첨부도면 도4에 도시한 바와같이 공기유통관(300)의 상단부에 자바라식 주름관과 같이 신축성이 있는 밀폐용기(400)를 결합하여 침수수위보다 더 많이 침수가 되었을 경우에도 공기유통관(300)을 통해 감압파일럿밸브(20)내부로 물이 침투하지 못하도록 구성할 수 도 있다.The present invention is coupled to the upper end of the air distribution pipe 300, such as bellows corrugated tube flexible stretch container 400 as shown in Figure 4, even when the water immersion more than the flooding water level 300 It may also be configured to prevent water from penetrating into the decompression pilot valve 20 through the).
본 고안은 상기와 같은 일실시예들에 의해 결코 한정되는 것이 아닌 것으로,The present invention is not limited by the one embodiment as described above,
상기 밀폐용기(400)의 경우 용기자체에 신축성이 있도록 구성하여 압력의 변동에 따라 신축되면서 공기압의 변동에 대응하도록 동작하는 밀폐용기(400)라면 모두 포함된다 할 것이며, 공기유통관(300)의 선단부에 밀폐용기(400)를 결합할 경우에는 공기유통관(300)의 길이를 짧게 형성하여도 무방하다할 것이다.In the case of the airtight container 400, all the airtight vessels 300 will be included if the airtight container 300 is configured to be elastic so that the container itself operates to respond to changes in air pressure while being stretched according to pressure fluctuations. When the airtight container 300 is coupled to the air flow pipe 300 may be formed to have a short length.
즉, 본 고안의 단순한 변경 내지는 치환한 것이라면 모두 본 고안의 기술범주내에 속한다 할 것이다.In other words, any simple modification or replacement of the present invention will fall within the technical scope of the present invention.
상기와 같은 본 고안의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention as described above are as follows.
먼저 첨부도면 도2 내지 도3b과 같이 공기유통구멍(20a)에 공기유통관(300)을 결합하되, 공기유통관(300)의 상단부를 침수수위보다 높은 곳에 위치되도록 수직으로 길게 연결설치한 경우에는 침수시에도 침수수위보다 공기유통관(300)의 상단부가 높은곳에 위치하므로 공기유통관(300)을 통해 감압파일럿밸브(20)내부로 물이 절대로 침투하지 못하게 된다.First, the air flow pipe 300 is coupled to the air flow hole 20a as shown in FIGS. 2 to 3B, but when the upper end of the air flow pipe 300 is vertically installed to be positioned above the water immersion level, the water is flooded. Since the upper end of the air distribution pipe 300 is located higher than the flooded water level, water never penetrates into the decompression pilot valve 20 through the air distribution pipe 300.
또한, 도4와 같이 상기 공기유통관의 선단부에 자바라식 주름관과 같이 신축성이 있는 밀폐용기(400)를 결합한 경우에는 상기 밀폐용기(400)자체가 신축성이 있으므로 셋팅압력의 변동이 있거나 일차측압력의 변동이 있더라도 밀폐용기(400)자체가 신축되면서 감압파일럿밸브(20)의 스프링케이스(23) 내부의 공기가 원활하게 유통되면서 압력의 변동에 적절히 대응하므로 감압파일럿밸브(20)의 작동에는 전혀 이상이 없으면서도, 침수수위보다 더 높히 침수가 되어서 공기유통관(300)의 선단부가 물에 잠기더라도 밀폐용기(400)에 의해 공기유통관(300)의 선단이 밀폐되어 있으므로 공기유통관(300)을 통해 감압파일럿밸브(20)내부로 물이 절대로 침투하지 못하게 된다.In addition, as shown in Figure 4 when the flexible container, such as a bellows corrugated tube, is coupled to the front end of the air distribution pipe, because the airtight container 400 itself is elastic, there is a change in the setting pressure or the primary side pressure Even if there is a fluctuation, the airtight container 400 itself is expanded and contracted so that the air in the spring case 23 of the decompression pilot valve 20 flows smoothly and appropriately responds to the fluctuation of the pressure. Without this, even if the tip end of the air distribution pipe 300 is submerged higher than the immersion water level is submerged in water because the tip of the air distribution pipe 300 is sealed by the airtight container 400 to decompress through the air distribution pipe (300) Water never penetrates into the pilot valve 20.
상기와 같은 본 고안은 메인방향밸브에 장착되는 감압파일럿(Pilot)밸브의일측에 형성된 공기유통구멍에 공기유통관의 하단부를 결합하고 상단부는 침수수위보다 높은 곳에 위치되도록 수직으로 길게 연결설치하여서, 침수시에도 공기유통관을 통해 감압파일럿밸브내부로 물이 침투하지 못하도록 함으로써, 침수시에도 공기유통구멍을 통해 감압 파일럿밸브내부로 물이 침투하지 못한다.The present invention as described above is connected to the lower end of the air distribution pipe formed in one side of the pressure reducing pilot (Pilot) valve mounted on the main directional valve and the upper end is installed vertically long so as to be located above the immersion water level, flooding When the water does not penetrate into the decompression pilot valve through the air distribution pipe, the water does not penetrate into the decompression pilot valve through the air distribution hole even when inundated.
이는 상기 공기유통관의 선단부에 자바라식 주름관과 같이 신축성이 있는 밀폐용기를 결합한 경우에도 마찬가지이다.This is also the case when a flexible container, such as a bellows corrugated pipe, is coupled to the front end of the air distribution pipe.
따라서, 본 고안은 감압파일럿밸브 일측에 형성된 공기유통구멍을 통해 감압파일럿밸브내부에는 물이 전혀 침투하지 못하므로 이에 구비되어 2차측압력을 셋팅하는데 사용되는 스프링이 녹슬거나 부식될 염려가 전혀 없어서 오동작이 일어나거나 감압밸브로서의 제기능을 못하게 되는 일이 전혀 없게 된다.Therefore, the present invention does not penetrate water inside the decompression pilot valve at all through the air flow hole formed on one side of the decompression pilot valve, so there is no fear of rust or corrosion of the spring used to set the secondary pressure. This will not happen or it will not function as a pressure reducing valve at all.
또한, 워터햄머의 발생이 전혀 없고, 배관을 파손할 염려가 전혀 없으며, 감압밸브 출구쪽 기계의 수명을 단축시키는 일 또한 전혀 없어서 밸브차체는 물론 이와 연관된 배관 및 주변기계 전체의 사용수명을 장구하게 하며 유지,보수 및 관리가 매우 편리한 등의 여러가지 효과가 있는 매우 획기적인 고안이다.In addition, no water hammer is generated, there is no fear of damaging the pipes, and the life of the machine at the outlet of the pressure reducing valve is not shortened. It is a very innovative design with various effects such as very easy to maintain, repair and manage.
