Abstract

[목적][purpose]

급탕기의 급수계 밸브유니트의 배수를 효율좋게 할 수 있도록 한다.So that the drainage of the water supply system valve unit of the water heater can be made efficient.

[구성][Configuration]

밸브케이싱(50)내의 스톱밸브용 밸브실(51a)을 구획하는 밸브시트(510)에 형성한 밸브구멍(51b)을 폐색하는 다이어프램밸브(511)를 배수시에 다이어프램(511a)의 탄성복원력에 의하여 개방되도록 구성한다.The diaphragm valve 511 for closing the valve hole 51b formed in the valve seat 510 for partitioning the valve chamber 51a for the stop valve in the valve casing 50 is connected to the elastic restoring force of the diaphragm 511a .

Claims (1)

급탕기의 열교환실로의 통수를 제어하는 급수계 밸브유니트에 설치되는 스톱밸브로서, 벨브케이싱내의 스톱밸브용 밸브실을 구획하는 밸브시트와, 밸브시트에 형성한 밸브구멍을 개폐하는 다이어프램밸브와, 밸브실에 대하여 다이어프램밸브에 의하여 간막이되는 배압실에 수납되며 스프링에 의해서 다이어프램밸브측으로 탄지되는 바이패스밸브를 구비하고, 다이어프램밸브에 밸브실과 배압실을 연통시키는 오리피스구멍과 배압실을 밸브구멍에 연통시키는 바이패스구멍을 형성하여, 통상시에는 바이패스구멍을 바이패스밸브로 폐색하고, 외부조작에 의하여 바이패스밸브를 스프링에 저항하여 후퇴시켰을 때에 바이패스구멍이 개방되도록 한 것에 있어서, 상기 다이어프램밸브는, 수압 및 바이패스밸브의 스프링 힘이 작용하지 않는 자유상태에서는 밸브구멍을 개방하는 배압실측의 밸브개방위치로 다이어프램밸브를 구성하는 다이어프램의 탄성복원력에 의하여 변위되도록 구성한 것을 특징으로 하는 급탕기 스톱밸브.A stop valve provided in a water supply system valve unit for controlling the flow of water into a heat exchange chamber of a hot water heater, comprising: a valve seat defining a valve chamber for a stop valve in a valve casing; a diaphragm valve for opening / closing a valve hole formed in the valve seat; The diaphragm valve includes an orifice hole communicating the valve chamber and the back pressure chamber, and a back pressure chamber communicating with the valve hole. The diaphragm valve includes a diaphragm valve and a diaphragm valve. A bypass hole is formed so that the bypass hole is normally closed by a bypass valve and the bypass hole is opened when the bypass valve is retracted against the spring by an external operation, , A free state in which the spring force of the water pressure and the bypass valve does not act Standing in the hot water heater, it characterized in that the stop valve is configured to be displaced by the elastic restoring force of the diaphragm constituting the diaphragm valve with the valve opening of the back pressure chamber side to open the valve hole location. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
