본 발명은 슬러지 방지형 제수밸브 및 시트부를 형성시키는 방법에 관한 것으로, 보다 상세하게는 원통디스크와 접촉되어 수밀되는 밸브본체의 시트부가 다른 부품의 삽입없이 밸브본체 그 자체가 직접가공되어 형성되고, 원통디스크의 표면에 패킹제가 코팅되어, 내구성과 수밀성이 향상된 슬러지 방지형 제수밸브와, 벨브본체의 시트부를 본체 하부의 축수를 가공할 때 동시에 가공함으로써 별도의 패킹링시트관이 불필요한 제수밸브의 시트부를 형성시키는 방법에 관한 것이다.The present invention relates to a method for forming a sludge-resistant distillation valve and a seat portion, and more particularly, the seat portion of the valve body which is contacted with the cylindrical disk to be watertight, is formed by directly processing the valve body itself without inserting other components. The sludge preventive valve is coated on the surface of the cylindrical disk to improve durability and watertightness, and the valve body seat is processed at the same time as the shaft part of the lower part of the main body is processed. A method of forming a part.

슬러지 방지형 제수밸브는 지하에 매설된 상수도관에 설치되어 상수도물의 공급과 차단을 하는 데 사용되는 밸브로서, 원통디스크가 회전되면서 물의 공급과 차단을 할 수 있게 함과 동시에, 밸브본체의 하부에 오목한 부분이 없는 구조가 가능하여 모래, 흙, 자갈 등 각종 이물질의 침적을 방지함으로써 완벽한 지수가 되도록 한 것이다.The sludge prevention type water valve is installed in the water supply pipe buried underground, and is used to shut off and supply the tap water.It allows the cylinder disk to rotate to supply and shut off the water and at the bottom of the valve body. It is possible to have a structure without concave parts, so as to prevent the deposition of various foreign substances such as sand, soil, gravel, and so on, so that it is a perfect index.

즉, 일반적인 제수밸브는 밸브본체의 내저면에 디스크의 회전축을 지지하는 오목한 요홈부가 형성하게 되어 있는데, 상수도물은 정수와 여과과정을 거쳤다 하더라도 자갈, 흙, 모래 등이 소량 포함되어 있으므로 이러한 이물질이 상기 오목한 요홈부에 침전되어 일정기간이 지나면 강한 수류에도 불구하고 흘러가지 않고 침적되게 된다. 따라서, 요홈부에 침적된 이물질에 의해 디스크시트와 밸브본체 시트의 밀착상태가 좋지 못하여 수밀성이 불량하게 되어 수도물의 막대한 유실을 주게 되었다.In other words, the general water valve is to form a concave groove for supporting the rotating shaft of the disk on the inner bottom surface of the valve body. Even though the tap water is purified and filtered, a small amount of gravel, soil, sand, etc. It is settled in the concave groove, and after a certain period of time, it is deposited without flowing despite the strong water flow. Therefore, due to the foreign matter deposited in the groove portion, the close contact between the disk seat and the valve body seat is not good, the water tightness is poor, which leads to a huge loss of tap water.

상기와 같은 문제점을 해소하고자, 디스크를 원통형으로 한 것이 개발되었는 데, 유입구와 유출구를 양측에 형성시킨 밸브본체에 수직샤프트를 수밀되게 축설시켜 이에 원통디스크를 고정 설치한 구조이다.In order to solve the above problems, the disc has been developed in a cylindrical shape, it is a structure in which the vertical shaft is condensed tightly to the valve body formed on both sides of the inlet and outlet to fix the cylindrical disk.

상기의 원통디스크는 밸브본체의 내경에 대응하는 통수공이 양측에 대향되게 형성되어 관로를 0~90°회전 범위내에서 개방하는 형상이고, 저면 중심에는 회전축이 형성되어 밸브본체의 오목한 축수부에 형성된 관형의 축수에 회전가능하게 설치된 구조이다.The cylindrical disk has a shape in which a through hole corresponding to the inner diameter of the valve body is formed opposite to both sides to open the conduit within a range of 0 to 90 ° rotation, and a rotating shaft is formed at the bottom center to form a concave shaft portion of the valve body. It is a structure rotatably installed in the tubular shaft.

그리고 밸브본체의 유입구와 유출구의 각각의 내부에는 선단에 패킹링이 원통디스크의 외벽면에 밀착되도록 설치된 패킹링시트관이 삽입되어, 원통디스크가 회전할 때 패킹링과 접면되면서 회전되어 수밀이 유지되는 구조를 가진다.And the inside of each of the inlet and outlet of the valve body is inserted into the packing ring seat tube is installed so that the packing ring is in close contact with the outer wall surface of the cylindrical disk, rotates while contacting the packing ring when the cylindrical disk rotates to maintain watertightness It has a structure.

그러나 상기와 같은 구조에 있어서는, 패킹링이 패킹링시트관의 선단 주연부에 좁은 면적으로 접착되거나 삽입되어 있으므로, 밸브의 잦은 작동에 의해 마모가 촉진되거나 떨어져 나가는 문제점이 발생하게 된다. 그리고, 수밀을 위해 별도의 패킹링시트관을 제조하여야 하고, 이를 삽입하기 위하여 유입구와 유출구의 내면을 가공하여야 하며, 페킹링의 형상을 위해 별도로 성형하여 제조하여야 하는 제조상의 많은 문제점들이 있게 된다.However, in the structure as described above, since the packing ring is bonded or inserted into a narrow area around the distal end of the packing ring sheet tube, frequent problems with the valve may cause abrasion to occur or to fall off. Then, a separate packing ring sheet tube must be manufactured for watertightness, and the inner surfaces of the inlet and outlet ports must be processed to insert the same, and there are many manufacturing problems to be manufactured by separately forming the shape of the peking ring.

본 발명의 목적은 상기와 같은 종래의 문제점을 해소하기 위하여, 패킹링시트관을 대신하는 시트부를 밸브본체에 일체로 형성시키고, 원통디스크의 외면에 패킹제를 코팅하여, 종래의 페킹링이 선단에 부착된 패킹링시트관이 불필요하게 됨으 로써, 제조상의 잇점은 물론이고, 수밀성 및 내구성이 향상된 원통디스크로 개폐되는 슬러지 방지형 제수밸브를 제공함에 있다. 그리고 밸브본체의 시트부를 간단하게 형성시키기 위한 방법을 제공함에 있다.An object of the present invention is to solve the conventional problems as described above, by forming the seat portion in place of the packing ring seat tube integrally to the valve body, and coating the packing agent on the outer surface of the cylindrical disk, the conventional peking ring tip Since there is no need for the packing ring seat attached to the tube, as well as manufacturing advantages, to provide a sludge-proof type water valve that opens and closes the cylindrical disk with improved watertightness and durability. And it provides a method for simply forming the seat portion of the valve body.

본 발명에 의한 슬러지 방지형 제수밸브는 유입구(1)와 유출구(2)가 양측에 형성되고 상부에 설치공(3)이 형성되며 저면에 형성된 오목한 축수부(4)에 관형의 축수(5)가 형성된 밸브본체(6); 상기 설치공(3)을 폐구시키고 수직샤프트(7)를 수직으로 축지하는 샤프트지지판(8); 상기 수직샤프트(7)의 하단부에 고정되어 밸브본체(6)의 내부에서 회전되고, 밸브본체(6)의 내경에 대응하는 통수공(9)이 양측에 대향되게 형성되며, 저면 중심에 회전축(10)이 형성되어 밸브본체(6)의 축수(5)에 회전가능하게 삽입되어 지지된 원통디스크(11);를 포함하여 구성된 제수밸브에 있어서, 상기 원통디스크(11)의 표면에는 패킹제(12)가 코팅되고; 상기 유입구(1)와 유출구(2)는 밸브본체(6)의 내측에 돌출되게 형성되어, 유입구(1)와 유출구(2)의 밸브본체(6)의 내측으로 돌출된 단부의 주연부에는 원통디스크(11)와 수밀되게 접촉되는 시트부(13)가 형성됨에 특징이 있다.Anti-sludge distillation valve according to the present invention, the inlet (1) and the outlet (2) is formed on both sides, the installation hole (3) is formed on the upper side of the tubular bearing (5) in the concave bearing portion (4) formed on the bottom The valve body 6 is formed; A shaft support plate 8 which closes the installation hole 3 and vertically holds the vertical shaft 7; Is fixed to the lower end of the vertical shaft (7) is rotated inside the valve body (6), the through hole (9) corresponding to the inner diameter of the valve body (6) is formed opposite to both sides, the rotating shaft ( 10. A dilution valve configured to include a cylindrical disk 11 rotatably inserted into and supported by the shaft 5 of the valve body 6, wherein the surface of the cylindrical disk 11 includes a packing agent ( 12) is coated; The inlet 1 and the outlet 2 are formed to protrude inside the valve body 6, the cylindrical disk at the periphery of the end protruding inside the valve body 6 of the inlet 1 and outlet 2 It is characterized in that the sheet portion 13 in close contact with (11) is formed.

이와같이 된 본 발명은 원통디스크(11)의 회전에 의하여 상수의 흐름이 제어되는데, 원통디스크(11)의 통수공(9)과, 밸브본체(6)의 유입구(1)와 유출구(2)의 상대적인 위치에 의하여 이루어 진다. 원통디스크(11)의 회전은 상부에 연결된 수직샤프트(7)와, 하부에 형성된 회전축(10)을 중심으로 이루어지고, 회전의 원활화 를 위하여 필요개소에 베어링이 설치됨은 통상의 기술과 같다. 즉 상수의 흐름 제어는 원통디스크(11)의 통수공(9)이 밸브본체(6)의 내부 관로와 연통되는 정도에 따라 물의 통과량을 제어하게 되어 이루어 진다.In the present invention as described above, the constant flow is controlled by the rotation of the cylindrical disk 11, the through hole (9) of the cylindrical disk 11, the inlet (1) and the outlet (2) of the valve body (6) By relative position. The rotation of the cylindrical disk 11 is made about the vertical shaft 7 connected to the upper portion, and the rotating shaft 10 formed on the lower portion, and the bearing is installed in the necessary place for smooth rotation, as in the conventional art. That is, the flow control of the constant is made by controlling the passage amount of water according to the degree of communication of the water passage 9 of the cylindrical disk 11 with the internal conduit of the valve body 6.

원통디스크(11)는 회전하면서 시트부(13)와 수밀이 이루어져야 하는데, 본 발명에서는 시트부(13)를 가공하여 형성되고, 원통디스크(11)의 표면에는 패킹제(12)가 코팅되어 있다.The cylindrical disk 11 should be made of watertight with the sheet portion 13 while rotating, in the present invention is formed by processing the sheet portion 13, the packing agent 12 is coated on the surface of the cylindrical disk 11 .

종래의 경우 시트부(13)를 형성시키는 별도의 구조물인 패킹링시트관이 밸브본체(6)의 유입구(1)와 유출구(2)에 삽입되고, 밸브본체(6)의 내부에 돌출된 패킹링시트관의 주연부에 패킹링이 부착된 구조로 되어 있었다. 따라서 종래의 경우 패킹링이 밸브의 작동에 의해 떨어지는 내구성의 문제가 있었다.In the conventional case, a packing ring seat tube, which is a separate structure for forming the seat part 13, is inserted into the inlet 1 and the outlet 2 of the valve body 6, and the packing protrudes inside the valve body 6. The packing ring was attached to the periphery of the ring seat tube. Therefore, in the conventional case, there was a problem of durability that the packing ring is dropped by the operation of the valve.

그러나 본 발명은 주연부에 패킹링을 부착하는 구조가 아니라, 유입구(1)와 유출구(2)의 밸브본체(6) 내부의 돌출 단부를 매끈하게 가공하여 시트부(13)를 형성시킨 구조이다. 따라서 돌출되게 부착되어 떨어지기 쉬웠던 종래 패킹링의 단점을 극복할 수 있게 된다.However, the present invention is not a structure in which a packing ring is attached to the periphery, but a structure in which the protruding end of the inside of the valve body 6 of the inlet 1 and the outlet 2 is smoothly processed to form the seat 13. Therefore, it is possible to overcome the disadvantages of the conventional packing ring, which is protrudingly attached and easy to fall off.

그리고 본 발명은 수밀을 위하여 시트부(13)와 접촉되는 원통디스크(11)의 표면에 패킹제(12)가 코팅되어 있어, 수밀성이 향상된다. 패킹제(12)는 종래의 패킹링과 같은 라바(rubber) 등의 재질로 코팅될 수 도 있고, 내구성과 내마모성이 뛰어난 금속성의 재질로 코팅할 수도 있으며, 수밀성과 내구성이 있는 어떠한 재질로도 가능하는 것으로 하나의 실시예에 국한되지 않는다. 본 발명에서의 일실시예로서는 도 1에 도시된 바와 같은 라바 라이닝(rubber lining)이다.In the present invention, the packing agent 12 is coated on the surface of the cylindrical disk 11 in contact with the sheet portion 13 for watertightness, thereby improving watertightness. The packing agent 12 may be coated with a material such as a rubber such as a conventional packing ring, or may be coated with a metallic material having excellent durability and abrasion resistance, and may be made of any material having watertightness and durability. It is not limited to one embodiment. One embodiment in the present invention is a rubber lining (rubber lining) as shown in FIG.

이와 같은 본 발명의 구조는 종래의 패킹링시트관의 별도 제작이 필요없고, 이의 설치를 위하여 밸브본체(6)의 유입구(1)와 유출구(2)의 가공도 불필요하게 됨으로써, 제수밸브의 제조가 용이하게 된다.Such a structure of the present invention does not require the manufacture of a conventional packing ring seat tube, and the installation of the water inlet valve 1 and outlet 2 of the valve body 6 is also unnecessary for the installation thereof. Becomes easy.

이와 같은 구조를 가진 본 발명은 통상의 방법과 같이 모든 부분이 성형 또는 가공된 후 조립되어 완성품으로 제조된다. 그러나 상기의 특유한 구조에 의하여 밸브본체(6)의 시트부(13)를 아주 용이하게 제조할 수 있게 되는데, 이는 밸브본체(6)의 내부 하측에 축수(5)를 가공할 때 상부의 설치공(3)으로 도구를 넣어 동시에 시트부(13)를 가공할 수 있기 때문이다.The present invention having such a structure is assembled into a finished product after all parts are molded or processed as in a conventional method. However, it is possible to manufacture the seat 13 of the valve body 6 very easily by the unique structure, which is the upper installation hole when machining the bearing 5 in the lower side of the valve body 6 It is because the sheet part 13 can be processed at the same time by inserting a tool into (3).

축수(5)는 원통디스크(11)의 하부에 돌출된 회전축(10)이 지지되는 부분으로서, 성형된 밸브본체(6)의 상측부 설치공(3)을 통해 가공되는 부분이다. 따라서 축수(5)를 가공하는 공구는 동시에 시트부(13)를 가공할 수 있는 것으로 하거나, 별도로 가공하는 경우 그 도구는 정확한 중심에 의한 원통디스크(11)와의 접촉을 위하여 가공된 축수(5)에 회전중심을 지지할 수 있는 도구를 사용할 수 있게 된다.The bearing 5 is a portion on which the rotating shaft 10 protruding from the lower portion of the cylindrical disk 11 is supported, and is processed through the upper installation hole 3 of the molded valve body 6. Therefore, the tool for machining the bearing 5 may be capable of machining the seat 13 at the same time, or in the case of a separate machining, the tool may be machined for contact with the cylindrical disk 11 by the correct center. A tool can be used to support the center of rotation.

이와 같은 방법은 양측에 유입구(1)와 유출구(2)가 형성되고, 가운데 상부에 설치공(3)이 형성된 밸브본체(6)의 내부에 시트부(13)를 형성시키는 방법으로서, 밸브본체(6)의 내부에 유입구(1)와 유출구(2)의 내측단부가 돌출되게 밸브본체(6)를 성형하는 단계; 밸브본체(6)의 내부 하측의 축수(5)를 가공할 때, 유입구(1)와 유출구(2)의 내측 단부 주연부를 원통디스크(11)와 수밀되는 형상으로 시트부(13)를 동시에 가공하는 단계;로 이루어진다.Such a method is a method of forming the seat portion 13 in the valve body 6 in which the inlet 1 and the outlet 2 are formed at both sides, and the installation hole 3 is formed in the upper portion thereof. Shaping the valve body 6 such that the inner ends of the inlet 1 and the outlet 2 protrude in the interior of the 6; When machining the bearing 5 on the inner lower side of the valve body 6, the seat 13 is simultaneously processed into a shape in which the inner periphery of the inlet 1 and the outlet 2 are watertight with the cylindrical disk 11. It consists of.
