본 고안은 첵크밸브에 관한 것으로, 특해 상단부에 장방형의 작동봉을 갖는 플레이트를 장방형작동홈에 단순히 삽입시켜 회동자재되도록 하여서 관로상에 설치된 상태에서 유체의 역류를 방지하는 플레이트가 안정되게 작동되도록 한 신규한 형태의 첵크밸브에 관한 것이다.The present invention relates to a check valve, and in particular, a plate having a rectangular actuating rod at the upper end thereof is simply inserted into a rectangular actuating groove so as to be rotated so that a plate that prevents a backflow of fluid in a state where it is installed on a pipeline is operated stably. A novel type of check valve.

일반적으로 첵크밸브는 플레이트를 회동시켜서 밸브를 개폐시키는 것으로, 유체를 일방향으로만 흐르게 하며 유체의 역류를 방지하는 작용을 한다.In general, the check valve is to open and close the valve by rotating the plate, the fluid flows in only one direction and serves to prevent the back flow of the fluid.

또한 첵크밸브가 설치된 관로내의 양면에 작용하는 압력에 의하여 플레이트가 자동적으로 작동하게 되어있고, 플레이트가 안정되게 여닫을 수 있도록 탄성적으로 작동되는 자동작동스프링이 설치되어서 관로내의 압력차와 함께 플레이트의 신속한 작동을 보조한다.In addition, the plate is automatically operated by the pressure acting on both sides of the pipeline where the check valve is installed, and the auto-operating spring is installed elastically so that the plate can be opened and closed stably. Assist in operation.

종래기술에 의한 이러한 형태의 첵크밸브들은 단순히 한방향으로만 권취된 이들 자동작동스프링에 의하여 플레이트가 작동되도록 되어있으므로 구성부품의 숫자가 증가하여 불필요한 여러가지 조립공정을 필요로 한다. 또한 밸브본체에 자동작동스프링을 갖는 플레이트를 밸브봉으로 조립고정하므로 적어도 3번의 조립공정이 필요하고, 이에 따라서 생산비의 상승을 가져온다.These types of shank valves according to the prior art are designed to be operated by these automatic actuated springs which are simply wound in only one direction, thus increasing the number of components and requiring various unnecessary assembly processes. In addition, at least three assembly steps are required because the valve body is fixed to the valve body with a self-actuating spring as a valve rod, thereby increasing the production cost.

따라서 본 고안의 목적은 상기한 바와같은 단점을 해결하기 위하여 개발된 것으로써, 본 고안의 첵크밸브는 위와 같은 여러번의 조립공정이 불필요하고, 자동작동스프링을 설치하지 않고서도 종래기술과 동일한 효과의 첵크밸브의 본래의 기능을 수행할 수 있도록 한 신규한 형태의 첵크밸브를 제공하는데 본 고안의 그 목적이 있다.Therefore, the object of the present invention was developed to solve the above-mentioned disadvantages, the check valve of the present invention does not require a number of assembly processes as described above, and has the same effect as the prior art without installing an automatic operation spring. It is an object of the present invention to provide a novel type of check valve that enables the check valve to perform its original function.

본 고안의 다른목적은 장방형작동홈을 구비한 밸브본체와, 상기 밸브본체의 장방형작동홈에 삽입되어 작동되는 장방형의 작동봉을 구비한 플레이트로 구성된 지극히 간단한 구조의 첵크밸브를 제공하는데 본 고안의 그 목적이 있다.Another object of the present invention is to provide a check valve having a very simple structure consisting of a plate having a valve body having a rectangular operation groove, and a plate having a rectangular operation rod inserted into the rectangular operation groove of the valve body. The purpose is.

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.

제1도 내지 제 3도에서, 부호1은 첵크밸브를 표시하고, 부호2는 밸브본체, 부호3은 플레이트를 표시하며, 이 플레이트(3)는 상기한 밸브본체(2)에 힌지결합되어서 회동자재된다.1 to 3, reference numeral 1 denotes a check valve, reference numeral 2 denotes a valve body, and reference numeral 3 a plate, and the plate 3 is hinged to the valve body 2 and rotated. Material.

상기한 밸브본체(2)의 상단부에는 장방형작동홈(4)을 형성하되, 이 장방형작동홈(4)은 제3도에 도시한 바와같이 상방으로 α각 만큼 경사지게 형성하여서 후술하는 플레이트(3)가 삽입되어 작동시에 플레이트가 장방형작동홈에서 자연적으로 이탈되는 것을 방지하도록 하였다.A rectangular operation groove 4 is formed at the upper end of the valve body 2, and the rectangular operation groove 4 is inclined upward by α angle as shown in FIG. Is inserted to prevent the plate from deviating naturally from the rectangular working groove during operation.

한편, 상기한 장방형작동홈에 삽입되어 회동자재되는 플레이트(3)는 좌우 양단부에 작동봉(5)을 구성하고, 중앙부에는 플레이트(3)의 열림시에 과도한 열림을 방지하는 열림방지턱(6)을 일체로 구성하여서 된 것이다.On the other hand, the plate (3) inserted into the rectangular operating groove is rotated to constitute an operating rod (5) at both left and right ends, the opening prevention jaw (6) to prevent excessive opening at the opening of the plate (3) in the center portion It is made up of a unit.

이와 같이 구성된 본 고안의 첵크밸브는 플레이트(3)가양단부의 작동봉(5)에 의하여 밸브본체(2)의 장방형작동홈(4)에 삽입된 상태에서 자동작동스프링이 없어도 첵크밸브의 본래의 기능을 훌륭히 수행한다.The shank valve of the present invention configured as described above has the original shape of the shank valve even when there is no automatic operation spring in the state where the plate 3 is inserted into the rectangular operation groove 4 of the valve body 2 by the operation rod 5 at both ends. It does a great job.

그리고 플레이트(3)는 밸브본체(2)에 α각만큼 상향으로 경사지게 형성된 장방형작동홈(4)에 의하여 빠지지 않고 안정되게 회동작동되며, 열림방지턱(6)에 의하여 플레이트의 작동시에 과도한 열림이 방지되고, 인위적인 힘을 가하지 않는한 플레이트가 장방형작동홈(4)의 내부에서 빠져나오지는 않는다.And the plate 3 is rotated stably without falling out by the rectangular operation groove 4 formed to be inclined upward by α angle in the valve body 2, the excessive opening during the operation of the plate by the opening preventing jaw (6) The plate does not escape from the inside of the rectangular actuation groove 4 unless it is prevented and artificially applied.

밸브본체(2)에는 밀폐링(7)을 삽입하였기 때문에 플레이트(3)나 연결플랜지(도시안됨)와 체결시에 누수를 차단한다.Since the sealing ring 7 is inserted into the valve body 2, the water is blocked when the plate 3 or the connecting flange (not shown) is engaged.

본 고안의 첵크밸브는 단순히 플레이트(3)를 밸브본체(2)의 장방형작동홈(4)에 집어 넣으면 조립이 완성되므로 지극히 간단한 조립과, 자동작동스프링이 불필요하므로 구성부품갯수를 줄여서 생산원가를 혁신적으로 절감시킬 수 있는 제반 특,장점이 있다.The check valve of the present invention is simply assembled by inserting the plate (3) into the rectangular operation groove (4) of the valve body (2), so the assembly is extremely simple and the automatic operation spring is unnecessary, so the production cost can be reduced by reducing the number of components. There are many special features and advantages that can be innovatively reduced.
