Abstract

[목적][purpose]

급탕기용 스톱밸브에 관한 것으로서, 밸브케이싱(50)내의 스톱밸브용 밸브실(51a)을 구획하는 밸브시트(510)와, 밸브시트에 대향하는 다이어프램(511a)에, 밸브시트(510)에 맞닿아서 밸브구멍(51b)을 폐색하는 밸브체부(511b)를 형성하여 된 다이어프램밸브(511)를 구비한 것에 있어서, 다이어프램밸브(511a)에 무리한 힘이 작용하지 않도록 하여 내구성을 향상시킨다.The stop valve for a hot water heater is provided with a valve seat 510 for partitioning a stop valve valve chamber 51a in the valve casing 50 and a diaphragm 511a opposed to the valve seat, The diaphragm valve 511 is provided with the valve body portion 511b that closes the valve hole 51b so as to prevent the diaphragm valve 511a from applying an excessive force to improve the durability.

[구성][Configuration]

다이어프램밸브(511)의 밸브체부(511b)에, 다이어프램밸브(511)가 완전히 개방된 상태에서도 밸브구멍(51b)에 끼워져 있는 가이드부(511c)를 형성한다. 가이드부(511c)의 외측둘레에 통수홈(511d)을 형성하여 개방시에 이통수홈(511d)을 통하여 물이 흐르도록 한다.A guide portion 511c fitted in the valve hole 51b is formed in the valve body portion 511b of the diaphragm valve 511 even when the diaphragm valve 511 is completely opened. A water passage groove 511d is formed around the outer periphery of the guide portion 511c so that water flows through the communicating groove 511d when the guide portion 511c is opened.
