Description

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 개폐밸브의 전후작동으로 개폐소음이 발생하므로 개폐밸브를 전후로 작동하도록 하는 물탱크에서 유출되는 물과 히터원통관에서 히터열로 급팽창되는 온수유출의 압력을 최소화하고 개폐밸브의 소음이 외부로 전파하지 못하도록 역지변의 외부를 에워싸서 최대한으로 차단하는 방안이 필요하였다.Opening and closing noise is generated by the forward and backward operation of the reverse valve on / off, which is opened and closed by the thermal expansion pressure of the hot water by the heater heat of the heater cylinder tube, so the water flowing out of the water tank to operate the shutoff valve back and forth and the heater cylinder tube to the heater heat It was necessary to minimize the pressure of the rapidly expanding hot water outflow and to block the outside of the reverse valve to the maximum to prevent the noise of the on-off valve from propagating to the outside.

본 발명은 역지변의 원통체 좌측외부에 좌측내통과 좌측외통을 일정한 사이공간이 형성되게 이중으로 에워싸서 물탱크의 물이 좌측외통의 내부주연과 좌측내통의 외부주연과의 사이공간을 거쳐 좌측내통의 내부주연과 역지변 원통체의 외부주연과의 사이공간을 통해 지그자그로 유통하도록 하고 원통체 우측에는 우측내통과 우측외통을 일정한 사이공간이 형성되게 이중으로 에워싸서 히터원통관의 히터열로 급팽창하는 온수를 우측외통 중앙의 내향 관연결구의 외부주연과 우측내통의 내부주연과의 사이공간을 거쳐 우측내통의 외부주연과 원통체의 내부주연과의 사이공간을 통해 지그자그로 유통하도록 하여 물탱크에서 유출되는 물과 히터원통관에서 유출되는 온수의 유통압력을 최소화하고 역지변의 원통체 외부전체를 좌측 내,외통과 우측 내,외통으로 이중으로 에워싸고 다시 내,외통사이에 형성시킨 내,외향 사이공간으로 물이 유통하도록 하는 이중물층으로 구성시켜서 역지변에서 발생하는 개폐밸브의 개폐소음을 외향으로 발산하지 못하도록 차단한 것이다.The present invention encloses the left inner cylinder and the left outer cylinder in a double space so as to form a constant interspace between the left outer cylinder and the left outer cylinder on the left outer side of the reverse side of the cylinder, and the water in the water tank passes through the space between the inner periphery of the left outer cylinder and the outer periphery of the left inner cylinder. It distributes to the zigzag through the space between the inner circumference of the inner cylinder and the outer circumference of the reverse displacement cylinder, and surrounds the right inner cylinder and the right outer cylinder on the right side of the cylinder so as to form a constant space between the heater cylinders To distribute the hot water rapidly expanding to the zigzag through the space between the outer periphery of the inward pipe connection at the center of the right outer cylinder and the inner periphery of the right inner cylinder and the space between the outer periphery of the right inner cylinder and the inner periphery of the cylindrical body. Minimize the distribution pressure of the water flowing out of the water tank and the hot water flowing out of the heater cylinder tube It is surrounded by double inner and outer cylinders, and is composed of a double layer which allows water to flow into the inner and outer spaces formed between the inner and outer cylinders, and prevents the opening and closing noise of the on / off valve generated from the reverse valve to radiate outward. will be.

역지변의 원통체 외부를 좌측 내,외통과 우측 내,외통으로 에워싸고 이 내,외통 사이에는 일정한 사이공간이 형성되게 내,외향의 이중 사이공간으로 형성시켜서 물탱크의 물과 히터원통관의 온수의 유출압력을 최소화시키고 역지변의 원통체 외부를 좌측 내,외통과 우측 내,외통으로 이중으로 에워싸고 또한 내,외향의 이중 사이공간으로 인한 이중물층으로 구성시켜서 역지변에서 발생하는 개폐소음을 외향으로 발산하지 못하도록 차단하는 것이다.The outside of the cylindrical body of the reverse side is surrounded by the inner, outer and right and outer cylinders, and the inner and outer cylinders are formed between the inner and outer cylinders so that a constant interspace is formed between the water tank of the water tank and the heater cylinder tube.
