Abstract

PURPOSE: A check valve for a small size hot-water boiler is provided to prevent noises by operating four elliptical opening valves of a silicon rubber valve in the opening/closing of the valve. CONSTITUTION: A circular diaphragm(10) has a rectangular center hole(11), and four through holes(12) punched at regular intervals between the center and the edge. A silicon rubber valve(20) includes four elliptical valves(22) corresponding to the four through holes, and is press-fitted into the rectangular hole by a cone-shaped locking projection(23). A rectangular shaft(21) between the silicon rubber valve and the cone-shaped locking protrusion is inserted in the rectangular hole of the circular diaphragm in order to prevent noises.

소음을 방지한 소형 온수보일러용 역지변 {Check valve for small size hot-water boiler for preventing noise}Check valve for small size hot-water boiler for preventing noise}

본 발명은 히터원통관에 의한 온수의 열팽창을 이용하여 온수를 순환시키는 난방장치에서 온수의 열팽창으로 빈번하게 전후로 작동하는 역지변의 밸브 개폐작동으로 발생하는 소음을 방지 할수 있는 소음을 방지한 소형 온수보일러용 역지변에 관한 것이다.The present invention is a small hot water preventing noise that can prevent the noise generated by the valve opening and closing operation of the reverse valve frequently operating back and forth by the thermal expansion of the hot water in the heating device for circulating the hot water using the thermal expansion of the hot water by the heater cylinder tube It relates to reverse displacement for boilers.

물탱크의 물을 히터원통관의 히터열로 온수의 열팽창을 이용하여 온수를 순환시키는 난방장치에서 급팽창하는 온수가 물탱크 쪽으로 역류 할수 없도록 히터원통관의 입구에 역지변을 부설하였으나 온수의 열팽창으로 빈번하게 작동하는 역지변의 밸브 전후 개폐작동으로 소리가 과다하게 소음으로 작용하여 문제점이 되었다.In the heating device that circulates the hot water by using the thermal expansion of the hot water by using the thermal expansion of the hot water by the heater heat of the heater cylinder tube, a reverse valve is installed at the inlet of the heater cylinder tube so that the hot water that expands rapidly cannot flow back to the water tank. As a result of the frequent opening and closing operation of the valve, which is frequently operated, the sound acts excessively as a noise, which is a problem.

히터원통관의 히터열에 의한 온수의 열팽창 압력으로 개폐작동하는 역지변의 개폐밸브를 지금까지는 역지변의 개폐밸브가 전체적으로 전후 작동하여 개폐작동을 하므로서 개폐소음이 발생하므로 역지변의 개폐밸브를 부분적인 작은 동작으로 소음을 최소로 줄이는 방법이 필요하였다.The reverse valve on / off valve that opens and closes by the thermal expansion pressure of hot water by the heater heat of the heater tube until now has been opened and closed by operating the valve back and forth as a whole. A small action required a way to minimize noise.

Conical locking projections in the center opposite to the curved direction of the thin silicon rubber valve 20 formed to bend the four elliptical opening and closing sides 22 outwards corresponding to the four through holes 12 of the round circular plate 10. As the 23, the tip 24 is inserted into the rectangular through hole 11 at the center of the curved circular plate 10, and the conical locking protrusion 23 is press-fitted into the square through hole 11. Square shaft (21) between the rubber valve 20 is to be fitted in the rectangular through-hole 11 of the curved circular plate 10 Four elliptical opening and closing sides 22 of the thin silicone rubber valve 20 when the thermal expansion of the hot water due to the heater heat of the heater cylinder tube is the expansion pressure of the curved circular plate 10 in the middle of the cylindrical body 1 Close the four through-holes 12 in close contact to prevent hot water from flowing back to the water tank, and when the pressure inside the heater cylinder drops after the hot water flows out of the heater tube through the heat expansion to the heating pipe, the water connected to the opposite side of the reverse valve is reversed. The water in the tank pushes the four elliptical opening and closing sides 22 of the thin silicon rubber valve 20 to the opposite side through the four through holes 12 of the curved circular plate 10 in the middle of the cylindrical body 1. Thin silicon coupled to the central axis of the curved circular plate 12 in the middle of the cylinder body 1 by opening and closing the water in the water tank 3 to flow into the heater cylinder tube. Four ovals with rubber valve (20) outward The opening and closing while pyebyeon 22 before and after the operation, so that it is possible to prevent the switching noise of the valve.

그리고 원통체(1) 내부 중간의 만곡진 원형격판(10)과 이에 밀접되는 두께가 얇은 실리콘 고무밸브(20)를 같은 방향으로 만곡지게 형성시키므로서 만곡진 원형격판(10)의 4개 통공(12)에 두께가 얇은 실리콘 고무밸브(20)의 4개 타원형 개폐변(22)이 만곡면으로 밀접되어 전후 작동으로 개폐가 되므로 개폐작동을 보다 확실하게 할수 있고 또한 원통체(1) 내부 중간의 만곡진 원형격판(10)의 중심 사각통공(11)에 끼워지는 실리콘 고무밸브(20)와 원추형돌기(23)를 중심 사각축(21)으로 결합시키므로서 만곡진 원형격판(10)의 4개 통공(12)과 중심축으로 결합하는 실리콘 고무밸브(20)의 4개 타원형 개폐변(22)이 개폐작동 중 중심축이 일부 회전되어 4개 통공(12)에 4개 타원형 개폐변(22)이 이탈되는 것을 방지하였다.The four circular holes of the curved circular plate 10 are formed by forming the curved circular plate 10 in the middle of the cylindrical body 1 and the thin silicon rubber valve 20 in close contact therewith to be curved in the same direction. The four elliptical open / close sides 22 of the thin silicone rubber valve 20 are close to the curved surface to be opened and closed by the forward and backward operation, thereby making the opening and closing operation more reliably and also in the middle of the cylindrical body 1. Four of the curved circular plate 10 by combining the silicone rubber valve 20 and the conical projection 23 fitted into the central square hole 11 of the curved circular plate 10 by the central square shaft 21. Four oval opening and closing sides 22 of the silicone rubber valve 20 coupled to the through hole 12 and the central axis is partially rotated during the opening and closing operation, the four oval opening and closing sides 22 in the four through holes 12 This prevented the deviation.
