Description
본 고안은 세라믹 디스크형 앵글밸브에 관한 것으로, 보다 상세히는 유체 흐름의 차폐를 신속하게 함은 물론 보다 향상된 기밀성 및 내구성을 갖도록 함으로써 밸브의 개폐가 보다 완벽하게 이루어지도록 함과 아울러 제품의 신뢰성을 향상시킬 수 있도록 구성된 세라믹 디스크형 앵글밸브에 관한 것이다.The present invention relates to a ceramic disk-type angle valve, and more particularly, to facilitate the closing and closing of the fluid flow, as well as to improve the airtightness and durability, and to open and close the valve more fully and to improve the reliability of the product. It relates to a ceramic disc-shaped angle valve configured to be able to.
일반적으로, 앵글밸브는 공급받는 유체의 흐름을 90°전환시키기 위하여 급수측 배관과 토출측 배관 사이에 설치되며, 내부에는 유체의 흐름을 차폐하는 개폐장치가 구비되어 있다.In general, the angle valve is installed between the water supply side pipe and the discharge side pipe in order to switch the flow of the supplied fluid by 90 °, and is provided with an opening and closing device for shielding the flow of the fluid therein.
이와 같은 종래의 앵글밸브(10)는 도 1에 도시한 바와 같이 유입구(11a)와 배출구(11b)가 수직 수평으로 직교되어 연통되도록 형성된 밸브몸체(11)의 내부에 상기 유입구(11a)및 배출구(11b)와 연통되면서 상측 개구된 쳄버(11c)가 형성되고, 상기 유입구(11a)와 연통되는 쳄버(11c)의 바닥면에는 디스크시트(11d)가 형성되며, 상기 밸브몸체(11)의 상면에는 밸브커버(12)가 쳄버(11c)를 밀폐하도록 결합되고, 상기 밸브커버(12)에는 상단부에 핸들(13)을 갖는 밸브샤프트(14)가 상기 유입구(11a)와 일직선상에 놓이도록 수직으로 배치되며, 상기 밸브샤프트(14)의 하측 외주연과 밸브몸체(11)의 쳄버(11c) 내주연에는 각각 상호 치합되는 이송수나사부(14a)와 가이드암나사부(11e)가 형성되어 상기 핸들(13)에 의해 밸브샤프트(14)가 회전되면서 승강되도록 형성되고, 상기 밸브샤프트(14)의 하단부에는 상기 디스크시트(11d)에 안착되면서 유입구(11a)를 개폐하는 개폐디스크(15)가 결합되며, 상기 밸브샤프트(14)와 밸브커버(12)와 밸브몸체(11)사이에는 유체가 외부로 누수 되지 않도록 패킹(16)이 결합되고, 상기 개폐디스크(15)의 저면에 역시 유체의 누수를 방지하는 밀폐댐퍼(17)가 결합되어 구성된다.As shown in FIG. 1, the conventional angle valve 10 has the inlet port 11a and the outlet port inside the valve body 11 formed such that the inlet port 11a and the outlet port 11b communicate perpendicularly and horizontally. An upper opening chamber 11c communicating with 11b is formed, and a disk seat 11d is formed on the bottom surface of the chamber 11c communicating with the inlet 11a, and the upper surface of the valve body 11 is formed. The valve cover 12 is coupled to seal the chamber 11c, and the valve cover 12 is vertically disposed so that the valve shaft 14 having the handle 13 at the upper end thereof is aligned with the inlet port 11a. Disposed on the lower outer periphery of the valve shaft 14 and the inner periphery of the chamber 11c of the valve body 11, respectively, a feed water screw portion 14a and a guide female screw portion 11e are formed to be engaged with each other. The valve shaft 14 is formed to be elevated while being rotated by the 13, and the valve shaft Opening and closing disk 15 for opening and closing the inlet port (11a) is coupled to the lower end of the disk seat (11d), between the valve shaft 14 and the valve cover 12 and the valve body (11) The packing 16 is coupled to prevent the fluid from leaking to the outside, and a closed damper 17 is also coupled to the bottom of the opening / closing disc 15 to prevent the leakage of the fluid.
그러나, 이와 같은 종래의 앵글밸브(10)는 유체를 차단하기 위해 밸브샤프트(14)을 회전시켜 개폐디스크(15)를 하강시킬 경우, 상기 밸브몸체(11)의 유입구(11a)로 유입되는 유체의 압력이 개폐디스크(15)의 저면에 직접 작용하기 때문에 밸브샤프트(14)의 핸들(13)을 돌려 개폐디스크(15)를 디스크시트(11d)에 밀착시킴으로써 유체의 흐름을 차단하는 동작에 무리가 따르게 되는 문제점이 있었다.However, such a conventional angle valve 10, when the valve shaft 14 is rotated to lower the opening and closing disk 15 to block the fluid, the fluid flowing into the inlet (11a) of the valve body 11 Since the pressure of acts directly on the bottom of the opening / closing disk 15, the handle 13 of the valve shaft 14 is turned to bring the opening / closing disk 15 into close contact with the disk seat 11d. There was a problem to follow.
또한, 종래의 앵글밸브(10)는 개폐디스크(15)를 디스크시트(11d)에 밀착시켜 밀폐할 경우 상기 개폐디스크(15)와 결합된 밸브샤프트(14)을 여러번 회전시켜 개폐디스크(15)를 하강시켜야 함으로 시간이 오래 걸려 급한 상황에서 유체의 흐름을 신속하게 차단하지 못하는 문제점이 있었다.In addition, the conventional angle valve 10 rotates the valve shaft 14 coupled with the open / close disk 15 several times when the open / close disk 15 is in close contact with the disk seat 11d to open / close the disk 15. Since it has to take a long time there was a problem that can not block the flow of the fluid quickly in an emergency situation.
또한, 종래의 앵글밸브(10)는 고온 및 고압의 유체가 흐르는 관로 상에 설치될 경우 고온의 열에 의해 디스크시트(11d)에 결합된 밀폐댐퍼(17)나 상기 밸브커버(12)와 밸브샤프트(14)의 결합면 사이에 내재된 패킹(16) 등이 과열되면서 변형되며, 특히 밸브샤프트(14)를 회전시켜 개폐디스크(15)를 승강 시킬 경우 상기 밸브커버(12)와 밸브샤프트(14) 사이에 내재된 패킹(16)이 열에 의해 변형됨과 아울러 상기 밸브커버(12)와 밸브샤프트(14)의 마찰력에 의해 비틀림이 발생되면서 찢어지게 됨으로 상기 부위로 유체가 누수되어 밸브로써의 기능을 상실하게되는 문제점이 있었다.In addition, the conventional angle valve 10 is a closed damper 17 or the valve cover 12 and the valve shaft coupled to the disk seat 11d by a high temperature heat when installed on a pipeline through which high temperature and high pressure fluid flows. The packing 16 and the like, which are inherent between the engaging surfaces of the 14, are deformed while being overheated. The inner packing 16 is deformed by heat and the torsion occurs due to the friction between the valve cover 12 and the valve shaft 14. There was a problem of being lost.
본 고안은 상기한 바와 같은 문제점에 착안하여 제안된 것으로, 그 목적은 보다 향상된 기밀성 및 내구성을 갖도록 함으로써 밸브의 개폐가 보다 완벽하게 이루어지고록 함과 아울러 제품의 신뢰성을 향상시킴은 물론 유체흐름의 차폐가 신속하게 이루어질 수 있도록 구성된 세라믹 디스크형 앵글밸브를 제공하고자 하는 것이다.The present invention has been proposed in view of the problems described above, and its purpose is to have a more perfect airtightness and durability, thereby opening and closing the valve more perfectly, and improving the reliability of the product as well as the fluid flow It is an object of the present invention to provide a ceramic disc type angle valve configured so that shielding can be made quickly.
