3-WAY VALVE AND BOILER SYSTEM HAVING ITS 3-WAY VALVE

摘要

The present invention, the diaphragm is applied by the differential pressure on the boiler system in the structure in which the three-way valve and the three-way valve to improve the operation mechanically.; Is attached as the present invention, a boiler, a heating object, and area in which the heating pipe and the hot water piping interconnect in the boiler system comprising a plurality of pipes in the three-way valve for discharging a constant predetermined flow rate, to one side the second branch pipe is coupled with the first engaging portion, it is formed a second engaging portion that is coupled to the return pipe in the other body part and being; On one side inlet faces the circulating pump of the other outlet portion is coupled hermetically to the body portion so as to face the heating target object, of the body part and the cost of water flowing from the inlet portion between the return pipe and the heating target object the head portion having a selected flow path for supplying the selected one side of the heating water pipe and; And the bottom portion has third coupling portion coupled to an end of the body portion which faces the head portion forming a predetermined chamber between said body portion and that the first branch pipe coupled to a portion; It is disposed on at least one side of said body portion, the head portion and the bottom portion to move mechanically by the differential pressure of the water stream flowing into the first branched pipe the flow path for selectively variable by the selected flow path including variants It characterized.
