본 고안은 첵크밸브에 관한 것으로, 특히 첵크밸브의 변체를 탄성적으로 지지하는 자동작동 스프링의 구조를 개선하여서 관로내에서 유체의 역류를 방지하는 변체가 안정되게 작동되도록 한 신규한 형태의 첵크밸브에 관한 것이다.The present invention relates to a check valve, in particular, a novel type of check valve in which a valve for preventing backflow of fluid in a pipeline is stably operated by improving the structure of an auto-operating spring that elastically supports the valve of the check valve. It is about.

일반적으로 첵크밸브는 변체를 회동시켜서 밸브를 개폐시키는 것으로, 유체를 일방향으로만 흐르게하며 유체의 역류를 방지한다.In general, the check valve is to open and close the valve by rotating the deformable body, to flow the fluid in only one direction and to prevent the back flow of the fluid.

그리고 밸브가 설치된 관로내의 양면에 작용하는 압력에 의하여 변체가 자동적으로 작동하게 되어있고, 변체가 안정되게 여닫을 수 있도록 탄성적으로 작동되는 자동작동스프링이 설치되어서 관로내의 압력차와 함께 변체의 작동을 보조한다.The valve is automatically operated by the pressure applied to both sides of the pipeline where the valve is installed, and the auto-operating spring is installed elastically so that the valve can be opened and closed stably. Assist.

종래기술에 의한 이러한 형태의 자동작동스프링들은 단순히 한방향으로만 권취된 스프링들을 설치하여서 이 스프링의 지지단부에 의하여 변체를 작동시키도록 되어있거나, 이와같은 구조로 된 스프링을 2개를 동시에 설치하여서 변체의 작동을 돕도록 되어있다.This type of automatic actuated springs according to the prior art is designed to actuate the deformable body by the supporting end of the spring simply by installing the springs wound in only one direction, or by installing two springs having the same structure at the same time. Is designed to help the operation.

이러한 형태의 스프링들은 변체의 여닫음에 감응할 수 있도록 작동되고 있으나, 예컨대 관로내의 유체의 압력이 균일하지 못하고 일방향으로 편중되게 작용할 경우에는 변체는 여닫음에 있어서 비틀림 응력이 작용하여 원활하지 못하다. 그러므로 변체는 관로내의 압력에 보다 정확히 작동될 수 없을 뿐만아니라 변체와 기밀을 유지하는 밀페링을 파손시키는 경우가 발생하고, 나아가서 첵크밸브의 수병을 단축하는 결과를 초래한다.The springs of this type are operated to respond to the opening and closing of the deformable body. For example, when the pressure of the fluid in the conduit is not uniform and acts in one direction, the deformable body is not smooth due to the torsional stress. Therefore, the deformed body can not be operated more accurately at the pressure in the pipe line, but also the case of breaking the sealing ring, which maintains the deformed body and the airtightness, can result in the shortening of the check valve.

따라서 본 고안의 목적은 상기한 바와같은 단점을 해결하기 위하여 개발된 것으로써, 본 고안의 첵크밸브는 체크밸브의 변체를 지탱시키는 자동작동 스프링의 구조를 특수하게 개선하여서 상기한 바와 같은 비틀림응력에 보다 효과적으로 대치하면서 안정되게 작동될 수 있는 신규한 형태의 첵크밸브를 제공하는데 있다.Therefore, the object of the present invention was developed to solve the above disadvantages, the check valve of the present invention to improve the structure of the self-actuating spring to support the deformation of the check valve to the torsional stress as described above It is to provide a novel type of check valve that can be operated more effectively and to replace more effectively.

이하 본 고안의 구성 및 작용효과를 첨부한 도면을 참고로 양호한 실시예를 상술하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1, 2도에서, 부호 1은 첵크밸브를 표시하고, 부호 2는 밸브 본체, 부호 3은 변체를 표시하며, 상기 밸브본체(2)에 변체(3)가 밸브축(5)을 축기점으로 힌지결합 되어있다.In Figs. 1 and 2, reference numeral 1 denotes a check valve, reference numeral 2 denotes a valve body, and reference numeral 3 denotes a variant, and a variant 3 on the valve body 2 causes the valve shaft 5 to be a shaft point. Hinged together.

그리고 상기 변체(3)는 밸브축(5)을 기점으로 작동되는 자동작동스프링(4)에 의하여 탄력적으로 지지되어있고, 밸브본체(2)에는 밀페링(10)을 삽입하여서 변체(3)와의 누수를 차단하도록 되어있다.And the deformable body (3) is elastically supported by an automatic actuated spring (4) actuated from the valve shaft (5), the valve body (2) by inserting a milling ring (10) with the deformable body (3) To prevent leakage.

본 고안의 특징적인 요부구성은 변체(3)를 지탱시키는 자동작동스프링(4)에 있다. 본 고안의 자동작동스프링(4)은 밸브축(5)에 결합되고, 서로 반대 방향으로 권회된 권취부(9a,9b)와, 이 권취부에서 변체로 연장설치된 텐션부(7)와, 이 텐션부의 끝단에 설치된 접지부(8)로 구성되어 있다.A key feature of the present invention lies in the self-acting spring 4 which holds the deformable body 3. The self-acting spring 4 of the present invention is coupled to the valve shaft 5, and wound portions 9a and 9b wound in opposite directions, a tension portion 7 extending from the winding portion to a deformed body, and It consists of the ground part 8 provided in the edge part of a tension part.

본 고안의 자동작동스프링(4)은 상기한 권취부(9a,9b)에 의하여 밸브축을 기점으로 자동작동스프링(4)의 탄성력을 양쪽에서 동일하게 유지하므로 변체(3)가 관로내의 압력에 의한 비틀림응력에 보다 효과적으로 대처한다.The automatic actuated spring 4 of the present invention maintains the elastic force of the automatic actuated spring 4 on both sides of the valve shaft by the windings 9a and 9b, so that the deformable body 3 is caused by the pressure in the pipeline. Copes with torsional stress more effectively

그리고, 텐션부(7)와 접지부(8)에 의하여 자동작동스프링(4)이 변체(3)의 중앙부 보다 넓은 부위에 안정되게 접지하여서 변체(3)를 항상 닫힘상태를 지탱시킨다.Then, by the tension part 7 and the grounding part 8, the automatic operation spring 4 stably grounds to a wider area than the central part of the deformable body 3 so that the deformable body 3 is always held in a closed state.

이와같이 구성된 본 고안의 첵크밸브는 밸브본체(2)에 작동되는 변체(3)의 작동을 자동작동스프링(4)에 의하여 보다 정확하게 안정되게 유지시키는 한편, 관로내의 압력차로 인하여서 첵크밸브의 변체(3)에 가해지는 비틀림응력에 자동작동스프링(4)이 효과적으로 대처하여서 첵크밸브의 작동 신뢰성을 향상시키고, 나아가서 첵크밸브의 수명을 연장시키는 등의 제반 특, 장점이 있다.The shank valve of the present invention configured as described above more accurately and stably maintains the operation of the transformer 3 acting on the valve body 2 by the automatic operation spring, while the valve of the shank valve due to the pressure difference in the pipeline ( The automatic actuating spring 4 effectively copes with the torsional stress applied to 3), thereby improving the operation reliability of the check valve and further extending the life of the check valve.
