구동방식으로는 핸들로 조작하는 수동식과 자동식으로는 전동기가 부착된 전동식, 에어실린더가 부착된 공압식으로 구분된다.The driving method is divided into manual operation with handle and automatic operation with electric motor and pneumatic with air cylinder.

종래의 공압식 나이프게이트밸브는 도 1a와 같이 통상적으로 요크(3) 상부 플랜지(4)에 에어실린더(5)를 결합하여 사용하였으나, 맨홀 안이나 천고가 높지 않은 곳에는 밸브 전체 길이가 길어 사용하지 못하고, 도 1b와 실용신안등록번호 20-0377773, 20-0276804에 도시된 바와 같이 바디(2) 양측면에 에어실린더(5),(5")를 결합하여 밸브 전체 길이를 줄인 공압식 나이프게이트밸브(1)를 사용하였다.Conventional pneumatic knife gate valve is used by combining the air cylinder (5) to the yoke (3) upper flange (4), as shown in Figure 1a, but the length of the valve is not used in the manhole or where the ceiling is not high. 1B and Utility Model Registration Nos. 20-0377773 and 20-0276804, pneumatic knife gate valves which reduce the overall length of the valve by combining the air cylinders 5 and 5 " 1) was used.

그러나 도 1b의 공압식 나이프게이트밸브(1)는 바디(2) 양측면에 2개의 에어실린더(5),(5")와 여기에 수반되는 에어배관(10), 솔레노이드밸브(11), 압력게이지(12), 에어휠터(13) 등의 부속품이 각각 2개가 필요하여 제조원가가 상승하고, 중앙제어실의 판넬과 솔레노이드밸브(11)에 연결되는 에어배관 등 시설비가 2배로 소요되며, 좌우측 에어실린더(5),(5")에 수반 되는 부품중 1개만 고장이 발생하여도 밸브작동이 되지 않는 문제점이 있다.However, the pneumatic knife gate valve 1 of FIG. 1B has two air cylinders 5, 5 "on both sides of the body 2, the accompanying air piping 10, a solenoid valve 11, and a pressure gauge ( 12) and two accessories such as the air filter 13 are required to increase the manufacturing cost, and the facility cost such as the air piping connected to the panel of the central control room and the solenoid valve 11 is doubled, and the left and right air cylinders (5) ), (5 ") has a problem that the valve does not operate even if only one of the parts involved.

본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 인출한 것으로서, 나이프게이트밸브 바디 플랜지 상부 일측면 중앙에 에어실린더를 결합하여 제조원가 및 시설비를 절감하고 작동을 원활히 할 수 있는 공압식 나이프게이트 밸브를 제공하는데 목적이 있다.The present invention is drawn to solve the problems as described above, by providing an air cylinder in the center of the upper side of the knife gate valve body flange to provide a pneumatic knife gate valve that can reduce the manufacturing cost and facility costs and facilitate operation. There is a purpose.

상기한 목적을 달성하기 위해 본 고안은 바디와 커버가 결합되고 밸브몸체 내부의 밸브대에 결합된 디스크가 승하강 되면서 유로실을 개폐하는 통상의 나이프게이트 밸브에 있어서, 바디 플랜지 일측면 중앙에 에어실린더를 결합 형성하고, 상기 에어실린더 로더 상부와 밸브대 상부에 연결대을 삽입하여 너트로 결합 형성한다. 상기 에어실린더는 상부와 하부에 ㄱ자형 요철을 취부하여 바디 일측면 중앙에 결합 형성되도록 구성한 것을 특징으로 하는 공압식 나이프게이트밸브를 제공한다.In order to achieve the above object, the present invention is a conventional knife gate valve for opening and closing the flow path chamber while the disk coupled to the body and the cover coupled to the valve seat inside the valve body is raised and lowered, the air in the center of one side of the body flange The cylinder is coupled to form, and the connecting rod is inserted into the upper portion of the air cylinder loader and the valve stem to form a coupling with a nut. The air cylinder provides a pneumatic knife gate valve, characterized in that it is configured to be coupled to the center of one side of the body by mounting the L-shaped unevenness on the top and bottom.

이하 본 고안에 의한 공압식 나이프게이트밸브를 첨부된 도면을 통해 상세하게 설명하면 다음과 같다.Hereinafter, the pneumatic knife gate valve according to the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안에 의한 나이프게이트 밸브(1)에 에어실린더(5)를 결합한 정면도로서 디스크(8)가 개방된 상태이며, 측단면는 디스크(8)가 폐쇄된 상태이고, 종래의 기술구성과 동일부재는 이해를 돕기 위해 동일부호를 사용하여 본 고안의 구성을 설명하기로 한다.2 is a front view in which the air cylinder 5 is coupled to the knife gate valve 1 according to the present invention, and the disk 8 is in an open state, and the side cross section is in a state in which the disk 8 is closed. The same member will be described the configuration of the present invention using the same reference numerals to help understanding.

도 2와 같이 본 고안은 바디(2)와 커버(6)가 결합되고 밸브몸체 내부의 밸브대(7)에 결합된 디스크(8)가 승하강 되면서 유로실(20)을 개폐하는 통상의 나이프게이트 밸브(1)에 있어서, 바디(2)의 플랜지(9) 상부 일측면 중앙에 에어실린더(5)를 부착하고, 상기 에어실린더 로더(10) 상부와 밸브대(7) 상부에 연결대(14)을 삽입하여 너트(15),(15')로 결합 형성한다.As shown in FIG. 2, the present invention is a conventional knife which opens and closes the passage chamber 20 while the disk 8 coupled to the valve seat 7 inside the valve body is coupled to the body 2 and the cover 6. In the gate valve (1), an air cylinder (5) is attached to the center of one side of the upper surface of the flange (9) of the body (2), and the connecting rod (14) on the upper part of the air cylinder loader (10) and the valve seat (7). ) Is inserted into the nut (15, 15 ') to form a coupling.

상기 에어실린더(5)는 상부와 하부에 ㄱ자형 요철(18),(18')을 취부하여 바 디(2)의 플랜지(9) 상부 일측면 중앙에 결합 형성한다.The air cylinder 5 is attached to the center of the upper side of the upper surface and the lower surface irregularities 18, (18 ') of the flange 9 of the body (2).

상기와 같이 구성된 본 고안에 의한 공압식 나이프게이트 밸브의 작용효과를 설명하면 다음과 같다.Referring to the effect of the pneumatic knife gate valve according to the present invention configured as described above are as follows.

솔레노이드밸브(11)를 작동에 의해 에어실린더(5) 하부 주입구(16)에 에어가 공급되면 에어실린더 로더(10)와 결합된 밸브대(7)가 상승하여 디스크(8)가 유로실(20) 개방하게 되며, 반대로 상부 주입구(17)에 에어가 공급하면 밸브대(7)가 하강하여 디스크(8)가 유로실(20)을 폐쇄시켜 관로를 차단하게 된다.When air is supplied to the lower inlet port 16 of the air cylinder 5 by operating the solenoid valve 11, the valve seat 7 coupled with the air cylinder loader 10 is raised to allow the disk 8 to pass through the passage chamber 20. When the air is supplied to the upper inlet 17, the valve stem 7 descends, and the disk 8 closes the passage chamber 20 to block the conduit.

그리고 에어실린더(5)가 바디(2) 플랜지(9) 상부 일측면 중앙에 바로 결합되어 밸브 전체 높이가 짧아져 맨홀 등의 천고가 낮은 곳에도 설치가 용이하게 된다.In addition, the air cylinder 5 is directly coupled to the center of one side of the upper portion of the body 2 flange 9 so that the entire height of the valve is shortened, so that it is easy to install in a place where the height of the manhole is low.

이상과 같이 본 고안에 의하면, 나이프게이트밸브 바디 플랜지 상부 일측면 중앙에 에어실린더를 결합 유로실을 개폐되도록 구성하여 맨홀 안의 천고를 줄이고 솔레노이드밸브, 압력게이지, 에어배관 등 수반되는 부속품을 절반으로 줄이는 생산원가 감소와, 공기압축기와 솔레노이드밸브와 연결되는 에어베관 등의 시설자재와 설치비 또한 반으로 줄일 수 있는 경제성과 운영 효율을 극대화 할 수 있는 공압식 나이프게이트밸브를 제공하는 것이다.As described above, according to the present invention, the air cylinder is coupled to the center of one side of the upper portion of the knife gate valve body flange to open and close the flow passage chamber, thereby reducing the height of the manhole and accompanying accessories such as solenoid valve, pressure gauge, and air pipe in half It is to provide a pneumatic knife gate valve that maximizes economic efficiency and operational efficiency, which can reduce production costs, facility materials and installation costs such as air pipes connected to air compressors and solenoid valves.
