본 고안은 유체가 수직으로 흐르는 관(Pipe)에 유니온조인트와, 첵밸브가 일체로 설치되여, 관의 이음과 유체의 역류를 방지하도록한 유니온조인트(union joint)겸용 첵밸브(check valve)에 관한 것이다.The present invention has a union joint and a check valve integrally installed in a pipe in which the fluid flows vertically, and a check valve for a union joint for preventing the joint of the pipe and the back flow of the fluid. It is about.

일반적으로 종래에는 수직으로 설치되는 관(Pipe)에 유니온조인트와 첵밸브를 서로 분리하여 체결 사용하였던바, 이는 첵밸브의 기능인 유체의 역류방지 역할을 정확하게 수행하지 못할 뿐만 아니라, 역류방지 기능을 수행한다 하더라도 유입구와 배출구의 압력차가 미세할 경우 상기 역류방지기능을 제대로 수행한다 하더라도 유입구와 배출구의 압력차가 미세할 경우에 특히 상기 역류방지기능을 제대로 수행하지 못하는 문제점이 있으며, 또한 상기 첵밸브를 설치하기 위해서는 향상 유니온조인트가 필요하게 되므로, 작업공정이 많을 뿐만 아니라, 그 작업효율도 떨어짐은 물론 보수에도 어려운 문제점이 있었다.In general, the union joint and the check valve are separately connected to and used in a vertically installed pipe, which does not accurately perform the role of preventing the backflow of the fluid, which is a function of the check valve, and also prevents the backflow function. Even if the pressure difference between the inlet and the outlet is fine, even if the reverse flow prevention function is properly performed, there is a problem in that the reverse flow prevention function is not properly performed especially when the pressure difference between the inlet and the outlet is minute, and the valve is installed. In order to do so, an improved union joint is required, which not only has a large number of work steps, but also reduces the work efficiency and has a difficult problem in repair.

본 고안은 상기와 같은 제반문제점을 해소하기 위하여 인출된 것으로 그 목적은 수직으로 설치되는 관(Pipe)에 유니온조인트와 첵밸브의 겸용으로 된 것을 결합시켜 주므로서 보수작업의 용이와 설치작업이 용이하여 작업효율을 높일수 있도록 함을 제공하는 것이다.The present invention is drawn out to solve the above problems. The purpose of this is to combine the union joint and the check valve with a pipe that is installed vertically so that the maintenance work is easy and the installation work is easy. To increase the work efficiency.

본 고안은 상기와 같은 목적으로 달성하기 위해 첨부된 도면에 따라 구체적으로, 설명하면 다음과 같다.The present invention will be described in detail according to the accompanying drawings to achieve the above object.

유입관(1)에 연결되는 유입구(2)와 배출관(3)에 연결되는 배출구(4)를 유니온조인트(5)로서 결합하여 연결하는 유니온조인트(6)에 있어서, 상기 유입구(2)는 일측으로, 플랜지(21)가 형성되고, 이 플랜지(21)의 일면에 재치부(22)와 밸브시이트(23)를 동일 평면상에 설치하되 그 사이에 환턱(24)을 돌설시키며, 이 환턱(24)에 홈(25)을 요설한다.In the union joint 6 which connects and connects the inlet port 2 connected to the inlet pipe 1 and the outlet port 4 connected to the outlet pipe 3 as a union joint 5, the inlet port 2 is one side. Thus, a flange 21 is formed, and the mounting portion 22 and the valve seat 23 are provided on one surface of the flange 21 on the same plane, and the recess 24 is protruded therebetween. The groove 25 is provided in 24.

또한 밸브체(7)는 상기 밸브사이트(23)를 열고 닫을 수 있게 보강편(71)이 일체로된 원형밸브(72)을 형성하고, 이 원형밸브(72)에 동심원상으로 환형의 고정부(73)를 형성시키되, 상기 원형밸브(72)와 환형의 고정부(73) 사이에 탄성체(74)로 연결구성한다.In addition, the valve element 7 forms a circular valve 72 in which a reinforcing piece 71 is integrally formed so as to open and close the valve site 23, and the circular valve 72 has a concentric annular fixed portion. A 73 is formed, and the circular valve 72 and the annular fixing portion 73 are connected to each other by an elastic body 74.

미설명부호 41은 배출구(4)의 단부이다.Reference numeral 41 is an end of the discharge port (4).

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

즉 수직으로 설치되는 유입관(1)에 유입구(2)를, 배출관(3)에 배출구(4)를 체결시킨후, 상기 유입구(2)의 플랜지(21)에 형성시킨 재치부(22)에 밸브체(7)의 환형 고정부(73)을 재치시킴과 아울러 환턱(24)에 형성되는 홈(25)내로, 밸브체(7)의 탄성체(74)가 끼이게 함으로써 유입구(2)의 밸브시이트(23)에 원형밸브(72)가 재치된다.That is, after the inlet 2 is fastened to the inlet pipe 1 which is installed vertically, the outlet 4 is fastened to the outlet pipe 3, and then to the mounting part 22 formed in the flange 21 of the inlet 2. By mounting the annular fixing portion 73 of the valve element 7 and causing the elastic body 74 of the valve element 7 to fit into the groove 25 formed in the annulus 24, the valve of the inlet port 2 is closed. The round valve 72 is mounted on the sheet 23.

그후, 유입구(2)의 재치부(22)에 재치되어 있는 밸브체(7)의 환형고정부(73)에 배출구(4)의 탄부(41)를 일치시켜서 유니온너트(5)로 배출구(4)를 체결하면 되는 것이다.Thereafter, the bullet part 41 of the outlet port 4 is matched with the annular fixing part 73 of the valve body 7 mounted on the mounting part 22 of the inlet port 2, and the outlet port 4 is connected to the union nut 5. ) Can be tightened.

따라서, 상기와 같이 조립된후, 수직으로 설치되는 우입관(1)으로 유체가 제2b도와 같이 화살표 방향으로 유입되면, 유입구(2)측의 밸브시이트(23)를 닫고 있던 원형밸브(72)는 밸브체(7)의 환형고정부(73)와 연결되는 탄성체(74)가 휘어져 열리게 되므로 유체는 수직방향으로 상승하면서 흐르게 되는 것이다.Therefore, when the fluid flows in the direction of the arrow as shown in FIG. 2B after being assembled as described above and vertically installed, the round valve 72 closing the valve seat 23 on the inlet 2 side. Since the elastic body 74 connected to the annular fixing portion 73 of the valve body 7 is bent open, the fluid flows while rising in the vertical direction.

또한 상기와 같이 유체가 수직방향으로 흐르다가 단수가 일어나는 경우에 수직방향으로 흐르던 유체는 유입구(2)측의 압력보다 배출구(4)측의 압력이 크르로 제2a도와 같이 화살표 방향으로 역류가 이루어진다.In addition, when the fluid flows in the vertical direction as described above, and the water flows in the vertical direction, the flow of the fluid flowing in the vertical direction is greater in the direction of the arrow as shown in FIG. 2a as the pressure at the outlet 4 side is greater than the pressure at the inlet port 2 side. .

이때, 배출구(4)측으로부터 역류가 이루어지면, 유입구(2)의 밸브시이트(23)를 열고 있던 원형밸브(72)가 유체의 압력에 의해 다시 닫히게 되어, 유체의 역류를 방지시킨다.At this time, if a reverse flow is made from the outlet 4 side, the circular valve 72 which opened the valve seat 23 of the inlet 2 is closed again by the pressure of a fluid, and prevents the back flow of a fluid.

또한 상기 원형밸브(72)내에는 보강편(74)을 끼워서 일체화시킴으로서 역류되는 유체압력에 견딜 수 있게 하는 것이 바람직하다.In addition, it is preferable to insert the reinforcing piece 74 in the circular valve 72 to integrate the reinforcing piece 74 so as to be able to withstand the backflow fluid pressure.

상술한바와 같이 본 고안은 유체가 수직으로 설치되는 관(Pipe)에 첵밸브가 일체로된 유니온조인트를 간편하게 체결하여 줌으로서, 유체의 역류방지는 물론, 구조가 간단하여 작업의 간편하고 보수가 용이하므로서 사용자에게 신뢰성을 줄수 있는 유용한 고안이다.As described above, the present invention provides a quick connection of the union joint in which the 첵 valve is integrated to a pipe in which the fluid is installed vertically, and prevents backflow of the fluid. It is a useful design that can give reliability to users while being easy.
