본 고안은 나이프게이트 밸브에 관한 것으로서, 보다 상세하게는 스템이 밸브 내부에 내장되고 본네트패킹과 바디패킹으로 형성된 이중 패킹으로 밸브의 기밀성과 설치공사비를 절감시킬 수 있도록 하는 나이프게이트 밸브에 관한 것이다.The present invention relates to a knifegate valve, and more particularly, to a knifegate valve that allows the stem to be embedded in the valve and the double packing formed of the bonnet packing and the body packing to reduce the airtightness and installation cost of the valve.

일반적으로 나이프게이트 밸브는 제지의 고농도 펄프, 상하수도의 슬러지, 쓰레기 이송관로 등 고농도 물질과 고형물을 이송하는 배관을 차단하는데 사용된다.In general, the knife gate valve is used to block the pipe for transporting high concentrations of materials and solids, such as high concentration pulp of paper, sludge of water and sewage, waste transport pipe.

특히 쓰레기자동집하시설은 아파트와 같이 공동주택의 쓰레기 투입구에 모인 쓰레기를 이송관로 통해 쓰레기집하장에 이송 처리하는 시스템으로, 상기 이송관로에는 흡입 송풍기로 쓰레기를 흡입하여 이송한다.In particular, the automatic waste collection facility is a system for transporting waste collected in a garbage inlet of a multi-unit house, such as an apartment, to a waste storage site through a transport pipe, and the waste pipe is sucked and transported by a suction blower.

종래에는 도1의 도a와 같이 나이프게이트 밸브(1)가 스템(4)의 상승으로 디스크(5)가 개폐되는 바깥나사식으로 디스크(5)가 100％ 열리면 전동개폐기(A) 상부로 스템(4)이 도출된다. 도b는 밸브가 닫힌 상태이다.Conventionally, as shown in FIG. 1A, the knife gate valve 1 is an external screw type in which the disk 5 is opened and closed by raising the stem 4, and when the disk 5 is opened 100%, the stem opens to the top of the electric switch A. FIG. (4) is derived. B is the valve closed state.

이는 스템(4)이 전동기개폐기(A) 상부로 도출되는 만큼 밸브 전체 길이가 크지고 밸브가 설치되는 수송관로의 공동구 높이가 비례적으로 크지므로 공사비가 높아지며, 장방형의 그랜드패킹(13)이 마모되면 밸브 몸체로 누기가 발생되는 문제점이 있다.As the stem 4 is led to the upper portion of the motor switch A, the overall length of the valve is increased and the height of the cavity of the transport pipe in which the valve is installed is increased proportionally, resulting in high construction cost and wear of the rectangular grand packing 13. There is a problem that the leakage occurs in the valve body.

여기에 실용신안등록 20-0427388의 전동 나이프게이트 밸브가 고안되었으나 이 또한 스템이 본네트 상부에 노출되어 도1 의 문제점을 해결 할 수 있는 근본적인 방안이 될 수 없었다.The electric knife gate valve of Utility Model Registration 20-0427388 was designed, but this could not be a fundamental solution to solve the problem of FIG.

본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 인출한 것으로서, 스템이 밸브 내부에 내장되고 본네트패킹과 바디패킹으로 형성된 이중패킹으로 밸브의 기밀성을 높이는 나이프게이트 밸브를 제공하는데 목적이 있다.The present invention is drawn out to solve the problems described above, it is an object to provide a knife-gate valve to increase the airtightness of the valve by the double packing of the stem is built in the valve and formed of the bonnet packing and body packing.

상기한 목적을 달성하기 위해 본 고안은 밸브 바디와 본네트가 결합되고 바디플랜지 상부에 스템가이드 요홈을 형성하고 디스크 상부 중심 일측에 결합한 슬리브에 스템을 삽입하여 바디플랜지 상부 스템가이드 요홈에 스템을 삽입 고정하고, 상기 스템 상부와 전동개폐기를 결합 디스크를 승하강 시키는 나이프게이트 밸브에 있어서,In order to achieve the above object, the present invention combines the valve body and the bonnet, forms a stem guide groove in the upper part of the body flange, inserts the stem into the sleeve coupled to one side of the disc upper center, and inserts the stem into the body flange upper stem guide groove. In the knife gate valve for raising and lowering the coupling disc and the stem top and the electric switch,

스템을 본네트패킹실에 삽입하여 본네트패킹으로 실링하고 밸브 바디 상부에는 장방형의 패킹실을 형성하여 디스크를 삽입 하여 바디패킹으로 실링하는 이중 패킹을 형성한 나이프게이트 밸브를 제공한다.The stem is inserted into the bone net packing chamber to seal with the bone net packing, and a rectangular packing chamber is formed on the valve body to provide a knife-gate valve having a double packing to insert the disc and seal the body packing.

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

도 2은 본 고안에 의한 나이프게이트 밸브(1)에 전동개폐기(A)를 결합한 부분정단면도 도a 및 측단면도 도b 이고, 종래의 기술구성과 동일부재는 이해를 돕기 위해 동일부호를 사용하여 본 고안의 구성을 설명하기로 한다.Figure 2 is a partial cross-sectional view a and side cross-sectional view of the electric switch (A) coupled to the knife gate valve (1) according to the present invention, and the same cross-sectional view of Figure b, the same members as in the prior art using the same reference numerals to help understanding. The configuration of the present invention will be described.

도 2와 같이 본 고안은 밸브 바디(2)와 본네트(3)가 결합되고 디스크(5)가 승하강 되면서 유로실(20)을 개폐하는 통상의 나이프게이트 밸브(1)에 있어서, 바디플랜지(6) 상부에 스템가이드 요홈(7)을 형성하여 디스크(5) 상부 중심 일측에 결합한 슬리브(8)에 스템(4)을 삽입하여 바디플랜지(6) 상부 스템가이드 요홈(7)에 스템(4)을 삽입 고정하고 상기 스템(4) 상부를 전동개폐기(A)와 결합하여 디스크(5)를 승하강 시키게 된다.As shown in FIG. 2, in the conventional knife gate valve 1 which opens and closes the passage chamber 20 while the valve body 2 and the bonnet 3 are coupled and the disk 5 is moved up and down, the body flange ( 6) The stem 4 is formed in the upper stem guide groove 7 of the body flange 6 by inserting the stem 4 into the sleeve 8 coupled to one side of the upper center of the disk 5 by forming the stem guide groove 7 at the top. ) Is fixed and the upper portion of the stem (4) is combined with the electric switch (A) to raise and lower the disk (5).

상기 스템(4)은 본네트패킹실(9)에 삽입 본네트패킹(10)으로 실링하고 밸브 바디(2) 상부에 장방형의 패킹실(11)을 형성하여 디스크(5)를 삽입 하고 바디패킹(12)으로 실링하는 이중패킹수단을 제공한다.The stem 4 is inserted into the bone net packing chamber 9 and sealed with the bone net packing 10, and a rectangular packing chamber 11 is formed on the valve body 2 to insert the disc 5 and the body packing 12. It provides a double packing means for sealing with).

상기 스템내장형 개폐수단을 통해 스템(4)의 회전에 의하여 디스크(5)가 승하강 유로실(20)을 개폐되도록 형성한다.The disk 5 is formed to open and close the elevating flow path chamber 20 by the rotation of the stem 4 through the stem built-in opening and closing means.

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

도 2의 도a와 같이 전동개폐기(A) 구동에 의해 스템이(4)이 제자리에서 회전하여 스템(4)에 연결된 슬리브(8)가 스템(4) 나사선을 따라 승강되고 스템(4)이 전동개폐기(A) 상부로 돌출 상승되지 않으므로 스템(4) 스토르크 만큼 전동 나이프게이트 밸브(1) 전체 길이가 짧아지므로 수송관로의 공동구 높이 및 일반 배관 천고가 낮은 곳에도 밸브 설치를 할 수 있다As shown in FIG. 2A, the stem 4 is rotated in place by driving the electric switch A so that the sleeve 8 connected to the stem 4 is elevated along the stem 4 thread and the stem 4 is moved. Since the total length of the electric knife gate valve (1) is shorter as much as the stem (4) torque, the valve can be installed even in the place where the height of the cavity of the pipeline and the height of the general pipe are low.

또한 밸브 바디(2)의 바디패킹(12)으로 쓰레기등의 고형물이 본네트(3)로 유입되는 것을 차단하여 디스크(5)의 상하 개페작동을 원활하게 하며 본네트패킹(10)에 의하여 누기를 완전하게 방지하게 되는 이중패킹 기능을 하게 된다.In addition, the body packing 12 of the valve body 2 blocks solids, such as waste, from entering the bonnet 3, thereby smoothly opening and closing the disk 5, and completely removing the leakage by the bonnet packing 10. The double packing function is prevented.

도a는 나이프게이트 밸브(1)의 디스크(5)가 50％ 정도 열린 상태를 나타낸 것이며, 미 설면된 부호(13)은 본네트 패킹그랜드이다.FIG. A shows a state where the disk 5 of the knife gate valve 1 is opened by about 50%, and an unspecified reference numeral 13 is a bonnet packing grand.

이상과 같이 본 고안에 의하면, 스템이 밸브 내부에 내장되고 본네트패킹과 바디패킹으로 형성된 이중 패킹으로 밸브의 기밀성을 높이며 설치공사비를 절감시킬 수 있도록 하여 쓰레기자동집하시설을 운영 효율을 극대화 할 수 있는 경제적인 나이프게이트 밸브를 제공하는 것이다.As described above, according to the present invention, the stem is built in the valve and the double packing formed by the bonnet packing and the body packing can increase the airtightness of the valve and reduce the installation cost, thereby maximizing the operation efficiency of the automatic garbage collection facility. It is to provide an economical knife gate valve.
