Abstract

A device for sealing a valve is provided to prevent leakage with only one gasket without an o-ring or a packing by using elastic seat ring to secure airtightness. A device for sealing a valve includes a valve body, a disk(20), and a seat ring. The valve body includes a flow passage, a main body(11) and a retainer(12). The main body has a retainer receiving groove(11a). The retainer is inserted into the retainer receiving groove. The main body allows a seat ring assembly to be easily assembled by inserting the retainer into the retainer receiving groove in a condition that the seat ring is inserted. The seat ring includes a coupling part(31) and an elastic supporting part. The coupling part is inserted into a seat ring coupling groove(12a) for elastically transforming the elastic supporting part. The elastic supporting part is elongated on a front end of the coupling part as a cantilever- type. The disk applies an external force to the seat part and transforms the seat part.

도 2 내지 도 5를 참조하면, 본 발명의 일실시예에 따른 밸브의 실링장치는, 유로(13)를 구비한 밸브몸체와, 상기 밸브몸체의 유로(13)를 개폐하는 디스크(20) 및, 상기 디스크(20)와 접촉하여 탄성변형하는 시트링(30)을 포함한다.2 to 5, the sealing device of the valve according to an embodiment of the present invention, the valve body having a flow path 13, the disk 20 for opening and closing the flow path 13 of the valve body and And a seat ring 30 elastically deformed in contact with the disk 20.

상기 밸브몸체는 리테이너 수용홈(11a)을 구비한 본체부(11)와, 상기 리테이너 수용홈(11a)에 삽입되는 리테이너(12)로 구성된다.The valve body is composed of a main body portion 11 having a retainer receiving groove 11a and a retainer 12 inserted into the retainer receiving groove 11a.

상기 본체부(11)는 상기 시트링(30)이 삽입된 상태에서 리테이너(12)를 리테이너 수용홈(11a)에 삽입함으로써 시트링(30)의 조립을 용이하게 한다.The main body 11 facilitates the assembly of the seat ring 30 by inserting the retainer 12 into the retainer receiving groove 11a in the state in which the seat ring 30 is inserted.

상기 리테이너(12)는 일측에 시트링 결합홈(12a)을 구비하고, 타측에 시트링 지지홈(12b)을 구비하고 있다.The retainer 12 has a seating coupling groove 12a on one side and a seating support groove 12b on the other side.

상기 시트링(30)은 상기 시트링 결합홈(12a)에 삽입되는 결합부(31)와, 상기 결합부(31)의 선단에 외팔보 형상으로 연장되어 형성되는 탄성지지부를 포함한다.The seat ring 30 includes a coupling part 31 inserted into the seat ring coupling groove 12a and an elastic support part extending in a cantilever shape at the tip of the coupling part 31.

상기 결합부(31)는 상기 시트링 결합홈(12a)에 삽입되어 고정됨으로써 탄성지지부가 탄성변형되도록 한다.The coupling part 31 is inserted into and fixed to the seating coupling groove 12a so that the elastic support part is elastically deformed.

상기 탄성지지부는 상기 결합부(31)의 선단에 절곡되어 형성된 연장부(32) 와, 상기 연장부(32)의 선단에 절곡되어 형성된 시트부(33) 및, 상기 시트부(33)의 선단에 절곡되어 형성된 자유단부(34)로 구성된다.The elastic support is an extension portion 32 formed by bending at the tip of the coupling portion 31, a sheet portion 33 formed by bending at the tip of the extension portion 32, and a tip of the sheet portion 33. It is composed of a free end portion 34 is bent to.

상기 연장부(32)와 시트부(33) 및 자유단부(34)는 전체적으로 'U'자형을 이루며 상기 결합부(31)의 선단에서부터 연속하여 형성되어 있다.The extension part 32, the seat part 33, and the free end part 34 form a 'U' shape as a whole and are continuously formed from the front end of the coupling part 31.

상기 연장부(32)는 외측에 요홈부(32a)가 함입되어 형성되어 있다.The extension portion 32 is formed by recessed in the groove portion (32a) on the outside.

상기 시트부(33)는 외측에 상기 디스크(20)와 접촉하는 시트면(33a)이 형성되어 있다.The sheet portion 33 is provided with a sheet surface 33a that contacts the disk 20 on the outside thereof.

상기 자유단부(34)는 선단이 상기 리테이너(12)의 시트링 지지홈(12b)에 삽입되어 지지된다.The free end portion 34 is supported by the front end is inserted into the seating support groove (12b) of the retainer (12).

상기 탄성지지부는 상기 디스크(20)와 접촉시 탄성변형한다. 즉, 도 5에 도시된 바와 같이, 상기 시트부(33)의 시트면(33a)에 디스크(20)와 접촉하여 압력이 가해지게 되면 시트면(33a)이 대략 0.5mm 정도 함입되면서 변형되고, 이와 동시에 상기 연장부(32)와 자유단부(34)가 휨모멘트를 받아 변형된다. 이때 발생하는 변형은 모두 탄성변형으로 디스크(20)를 시트면(33a)으로부터 후퇴시키게 되면 탄성지지부는 원래의 형상으로 복원된다.The elastic support portion elastically deforms when contacted with the disk 20. That is, as shown in FIG. 5, when the pressure is applied to the seat surface 33a of the seat portion 33 in contact with the disk 20, the seat surface 33a is deformed while being embedded by about 0.5 mm, At the same time, the extension part 32 and the free end part 34 are deformed under the bending moment. In this case, all of the deformations generated are elastic deformations, and when the disk 20 is retracted from the seat surface 33a, the elastic support portion is restored to its original shape.

다시 말하면, 상기 디스크(20)에 의해 상기 시트부(33)에 외력이 가해지게 되면상기 탄성지지부의 연장부(32)와 자유단부(34)는 판스프링의 역할을 하면서 시트부(33)를 탄성변형시키게 된다.In other words, when an external force is applied to the seat portion 33 by the disk 20, the extension portion 32 and the free end portion 34 of the elastic support portion serve as a leaf spring and serve as a leaf spring. Elastic deformation.

여기서, 상기 연장부(32)의 요홈부(32a)는 결합부(31)에 대하여 탄성지지부 전체에 모멘트가 크게 작용하도록 한다.Here, the recess 32a of the extension 32 allows the moment to act largely on the entire elastic support portion with respect to the coupling portion 31.

상기 시트면(33a)은 디스크(20)와 접촉된 상태에서 탄성지지부가 탄성적으로 변형함으로써 시트면(33a)에 대하여 디스크(20)가 미끄러지지 않게 되어 미끄럼 마찰에 의해 시트면(33a)과 디스크(20)의 표면이 마모되는 것을 방지할 수 있게 된다.The seat surface 33a is elastically deformed by the elastic support portion in contact with the disk 20 so that the disk 20 does not slip with respect to the seat surface 33a, and the seat surface 33a and the disk are caused by sliding friction. It is possible to prevent the surface of 20 from being worn.

상기 본체부(11)와 리테이너(12)의 사이로 고압의 유체가 유출되는 것을 방지하기 위해 가스켓(40)이 구비된다.A gasket 40 is provided to prevent the high pressure fluid from flowing out between the main body 11 and the retainer 12.

상기 가스켓(40)은 본체부(11)의 리테이너 수용홈(11a) 일측벽에 밀착되어 구비되되, 시트링(30)의 결합부(31)가 상기 리테이너(12)의 시트링 결합홈(12a)에 삽입된 상태로 리테이너(12) 및 시트링 결합부(31)와 접촉하게 된다.The gasket 40 is provided in close contact with one side wall of the retainer receiving groove 11a of the main body portion 11, and the engaging portion 31 of the seat ring 30 has the seat ring coupling groove 12a of the retainer 12. In contact with the retainer 12 and the seat ring engaging portion 31 in the state inserted into.

즉, 도 2와 도 5에 도시된 바와 같이, 상기 가스켓(40)은 리테이너(12) 및 시트링(30) 결합부(31)와 본체부(11) 사이에 삽입되어, 리테이너(12)와 본체부(11) 사이로 유체가 유출되는 것을 차단하게 된다.That is, as shown in FIGS. 2 and 5, the gasket 40 is inserted between the retainer 12 and the seat ring 30 coupling portion 31 and the main body portion 11, thereby retaining the retainer 12. It is to block the flow of fluid between the body portion (11).

상기 가스켓(40)은 고무재질과 석면이 압축형성되어 고온에서도 내구성을 갖게 된다.The gasket 40 has a rubber material and asbestos is compressed to have durability even at high temperatures.

상기 시트링(30)은 주물이 아닌 스테인레스 스틸 소재의 봉을 절삭가공하여 제조됨으로써 탄성이 일정하게 유지된다. 따라서, 절곡 제작시 탄성이 변화되는 단점을 해소하였다.The seat ring 30 is manufactured by cutting a rod of a stainless steel material, not a casting, thereby maintaining a constant elasticity. Therefore, the disadvantage that the elasticity is changed during bending production has been eliminated.

상기한 본 발명의 상세한 설명은 첨부된 도면에 따른 바람직한 실시예를 설명한 것에 지나지 않으며, 본 발명의 범위는 이에 한정되는 것이 아니다. 본 발명 의 기술적 사상을 벗어남이 없이 다양한 형태로 변형된 것은 본 발명의 범위에 포함된다.The above detailed description of the present invention is merely illustrative of preferred embodiments according to the accompanying drawings, and the scope of the present invention is not limited thereto. Modifications in various forms without departing from the spirit of the invention are included in the scope of the invention.

이상에서 설명한 바와 같이 본 발명에 따른 밸브의 실링장치에 의하면, 탄성을 지닌 시트링을 통해 기밀도가 높아져 가스켓 하나만을 사용하더라도 오링을 비롯한 패킹 없이도 누수를 방지할 수 있고, 시트와 디스크의 마찰에 의한 마모를 최소화할 수 있으며, 시트를 지지하는 별도의 탄성수단을 구비하지 않아 구조가 간단한 효과가 있다.As described above, according to the sealing device of the valve according to the present invention, the airtightness is increased through the seat ring with elasticity, and even if only one gasket is used, leakage can be prevented without packing, including an O-ring. It is possible to minimize the wear caused by, there is no separate elastic means for supporting the sheet structure has a simple effect.
