The invention discloses a fuel gas wall-hanging stove water outlet valve. The fuel gas wall-hanging stove water outlet valve comprises a valve body, a motor, a valve rod, a sealing ring, a spheroidal valve core, a blocking ring and a cushion ring. The spheroidal valve core is arranged in a valve core seat of the valve body. The valve rod is arranged in a valve rod hole of the valve body. One end of the valve rod is connected with a valve rod seat of the spheroidal valve core, and the other end is connected with the motor. The spheroidal valve core provided with an orthometric L-shaped channel is adopted, and the valve core seat, a first water outlet, a water inlet and a second water outlet are arranged on the base level of the valve body, according to working travel, the spheroidal valve core rotates around the origin by + / -90 degrees, and extra space is not occupied, so that the structure of the valve body is more compact and more reasonable, sealing between the spheroidal valve core and the cushion ring does not need additional external force, and can be finished only needing ensure the precision of manufacture and assembly, the fuel gas wall-hanging stove water outlet valve has the advantages that the sealing property is good, the service life is long, and leakage is not prone to happening.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a water outlet valve for a gas wall-hung boiler. Background technique [0002] With the improvement of people's living standards, homes with additional heating equipment are becoming more and more popular, thus promoting the development of gas-fired wall-hung boilers. The research on gas-fired wall-hung boilers in my country started in the 1980s. Furnace dual-purpose, to solve the application of modern living room heating and domestic hot water. The water outlet valve is an important part of the gas wall-hung boiler. The water outlet valve of the existing gas wall-hung boiler is a two-position three-way valve. Switching from heating mode to domestic hot water mode. The existing problems are: firstly, the stroke of the valve core is large during operation, which causes the external dimension of the valve body to become larger, which affects the structural design of the whole machi...
