본 고안은 관내를 흐르는 액체의 흐름을 개폐시키는 밸브에 역류를 방지하기위한 역류방지밸브체를 설치하여서된 밸브의 역류방지장치에 관한 것이다.The present invention relates to a non-return valve of the valve by installing a non-return valve for preventing the reverse flow in the valve for opening and closing the flow of liquid flowing through the pipe.

종래의 밸브는 도2에 도시한 바와같이 밸브보디(100)의 중간부에 형성한 칸막이(200)에 유출구멍(300)을 형성하여 상기의 유출구멍(300)을 밸브봉(400)에 고정한 밸브체(500)로 개폐시키게된 구조로 구성된 것이므로 칸막이(200)의 구석에는 찌꺼기등의 이물질이 쌓이게 될 뿐만 아니라 입구로 유입되는 액체는 유출구멍(300)을 90°로 돌아 출구로 배출케됨으로 흐름에 많은 저항이 걸리게 되어 수압이 하강되는 문제가 있고 고장시에는 메인밸브(MAIN VALVE)를 개폐시켜야하는 불편이 있음과 아울러 액체를 이송중 발생되는 역류는 전혀 방지할 수 없는 문제가 따르게 되었다.In the conventional valve, as shown in FIG. 2, the outlet hole 300 is formed in the partition 200 formed in the middle of the valve body 100 to fix the outlet hole 300 to the valve rod 400.

도1은 본 고안의 단면도로서1 is a cross-sectional view of the present invention

도1에 도시된 바와같이As shown in FIG.

밸브보디(1)의 삽입관(2)으로 구멍(5A)을 형성한 볼밸브체(5)를 삽입하여 볼밸브체(5)의 일부는 밸브보디(1)의 안치곡면(3)에 접촉시키고 볼밸브체(5)의 상부에는 밸브봉홀더(6)와 밸브봉(7)을 삽입하여 사각으로 형성된 밸브봉(7)의 단부는 볼밸브체(5)의 사각홈(5B)에 끼우고 패킹(8)과 캡(9)으로 고정하여 볼밸브체(5)를 회전시켜 통로(1')를 개폐시킬 수 있도록하고 밸브보디(1)와 일체로 하우징(4)을 형성하여 개구부는 덮개(10)로 개폐시킬 수 있도록하고 내부에는 역류방지밸브체(11)를 핀(12)으로 회전자유롭게 설치하여서된 것을 특징으로 한 것이다.A ball valve body 5 having a hole 5A is inserted into the insertion pipe 2 of the valve body 1 so that a part of the ball valve body 5 contacts the settle curved surface 3 of the valve body 1. The valve rod holder 6 and the valve rod 7 are inserted into the upper portion of the ball valve body 5 so that the end of the valve rod 7 formed in a square shape is fitted into the square groove 5B of the ball valve body 5. The packing 8 and the cap 9 so as to rotate the ball valve body 5 to open and close the passage 1 ', and the housing 4 is integrally formed with the valve body 1 so that the opening is Can be opened and closed by the cover 10 and the inside is characterized in that the non-return valve 11 is installed freely by the pin (12).

이와같이된 본 고안은 핸들과 밸브봉(7)에 의하여 볼밸브체(5)를 회전시켜 밸브보디(1)의 통로(1')를 개폐시키게되는 것으로서 볼밸브체(5)의 구멍(5A)를 통로(1')와 일치시키게되면 통로(1')와 구멍(5A)은 일직선으로 된다. 이에따라 액체는 직선으로 흐르게됨으로 이송저항이 많이 걸리지 않게되어 이송수압이 하강되는 일이 없게 되고 액체의 흐름은 원활하게 이루어지게 됨과 동시에 찌꺼기등의 이물질이 통로(1')에 쌓이는 것이 방지된다. 또한 볼밸브체(5)가 개방되어 액체가 도1의 실선화살표방향으로 흐를때에는 역류방지밸브체(11)는 액체의 이송수압에 의하여 도1의 점선표시와 같이 핀(12)을 축점으로하여 회전되어 들리게 되며 이상태에서 출구측에 점선화살표방향으로 역류가발생시에는 역류방지밸브체(11)는 도1의 점선화살표방향으로 하강되어 닫히게 된다. 이에따라 출구측에서 입구측으로 통로(1')를 통하여 역류되는 것이 방지된다.The present invention, as described above, rotates the ball valve body 5 by the handle and the valve rod 7 to open and close the passage 1 'of the valve body 1, and the hole 5A of the ball valve body 5 is provided. Is matched with the passage 1 ', the passage 1' and the hole 5A are straight. Accordingly, the liquid flows in a straight line so that the transfer resistance is not taken much so that the transfer hydraulic pressure is not lowered and the liquid flows smoothly and foreign matters such as debris are prevented from accumulating in the passage 1 '. In addition, when the ball valve body 5 is opened so that the liquid flows in the solid arrow direction of FIG. 1, the non-return valve body 11 has the pin 12 as the axial point as indicated by the dotted line in FIG. In this state, when the reverse flow occurs in the dotted arrow direction on the outlet side, the non-return valve body 11 is lowered and closed in the dotted arrow direction of FIG. This prevents backflow through the passage 1 'from the outlet side to the inlet side.

볼밸브체(5)로 통로(1')를 밀폐시켜 액체가 이동되지 않을시에는 역류방지밸브(11)는 자체의 무게에 의하여 하강되어 닫힌 상태로 유지된다. 그리고 본 고안의 구조는 도면에 도시된 것에 한정되는 것이 아니고 요지를 벗어나지않는 범위내에서 변화시킬 수 있다.When the liquid is not moved by sealing the passage 1 'with the ball valve body 5, the non-return valve 11 is lowered by its weight and kept in a closed state. And the structure of the present invention is not limited to that shown in the drawings and can be changed within the scope without departing from the gist.

이와같은 본 고안은 볼밸브체(5)로 구성하여 개방된 상태에서는 밸브보디(1)의 통로(1')와 볼밸브체(5)의 구멍(5A)이 일직선으로 되게 하였으므로 액체의 이송저항이 많이 걸리지않게되어 액체의 이송이 원활하게 이루어지게 됨과 아울러 통로(1')에 찌꺼기등의 이물질이 쌓이는 것이 방지되고 역류가 발생시에는 하우징(4)에 설치한 역류방지밸브체(11)에 의하여 역류를 방지할 수 있는 효과가 있다.The present invention is composed of the ball valve body (5) in the open state the passage (1 ') of the valve body 1 and the hole (5A) of the ball valve body 5 in a straight line, so the transfer resistance of the liquid This prevents the liquid from flowing smoothly and prevents the accumulation of debris, such as debris, in the passage 1 ', and prevents the accumulation of debris by the non-return valve body 11 installed in the housing 4 when backflow occurs. It is effective to prevent backflow.
