Claims

[Scope of utility model registration request]

A water valve, a hot water mixing faucet body equipped with a hot water valve, and a check valve disposed in a flow path on the upstream side of the water valve,
In the hot water mixer faucet, the water valve has a structure in which the water valve opens and closes by moving the water valve body toward and away from the water valve seat from the primary side,
The check valve is formed to have an outer diameter slightly smaller than the inner diameter of the flow channel, has a valve seat hole in the center, is slidably attached to the inner wall of the flow channel, and has a secondary end surface that is attached to the inner wall of the flow channel. a valve seat member that abuts a protruding step provided in a protruding shape; and a valve seat member having an outer diameter smaller than an outer diameter of the valve seat member and larger than an inner diameter of the valve seat hole, and corresponding to the valve seat hole from the secondary side. a disc-shaped valve body that opens and closes the valve seat hole;
It is formed into a bottomed cylindrical shape having an outer diameter smaller than the inside of the valve seat hole, and its bottom wall is fixed to the primary side of the valve body, and a water passage hole is formed in the middle of the cylindrical portion and projects outward at the open end. a guide member each having a flange portion, and a guide member disposed from the flange portion of the guide member to an inner step provided on the inner circumferential surface of the valve seat member to press the valve body against the secondary side end surface of the valve seat member. a spring disposed from a locking step provided in the primary flow path of the protruding step to an outer step provided on the outer circumferential surface of the valve seat member, the spring is arranged to extend from the locking step provided in the primary flow path of the protruding step to the outer step provided on the outer peripheral surface of the valve seat member; a spring that presses against the protruding step;
A hot water mixing faucet comprising a sealing member that seals between the outer circumferential surface of the valve seat member and the inner wall of the flow path.
