Claims

[Scope of Claim for Utility Model Registration] (1) In a metered water stop faucet equipped with a valve body seated on a valve seat in a valve body having an inlet and an outlet, a valve body installation chamber isolated from both the inflow port and the outflow port; an activation opening drilled in the valve body so as to communicate the valve body installation chamber and the outflow port; a starter valve that can be seated from the valve body installation chamber side to close the opening; an elastic body that biases the starter valve in the seating direction; a small hole that communicates the valve body installation chamber and the inlet; a cleaning pin loosely inserted into the small hole, the cleaning pin having a diameter of a portion inserted into the small hole when the valve body is seated than a diameter of a portion inserted into the small hole when the valve is opened. A quantitative water stop valve with a water hammer reduction structure characterized by a large volume. (2) In a metering stop valve equipped with a disc-shaped valve element, one side of which is seated on an annular valve seat within a valve body having an inlet and an outlet, the flow is controlled by the valve element seated on the valve seat. A valve body installation chamber that is isolated from both the inlet and the outlet; an activation opening drilled in the valve body so as to communicate the valve body installation chamber and the outlet; and a valve in the valve body. A starter valve that can be seated from the body installation chamber side to close the opening; an elastic body that urges the starter valve in the seating direction; and a small hole that communicates the valve body installation chamber and the inlet. , the side peripheral surface of the valve body is in slidable contact with the inner surface of the valve body installation chamber, and the inside surface of the valve body installation chamber has one side and the other side of the valve body when the valve body is not seated. A quantitative water stop valve with a water hammer reduction structure in which a groove is formed to communicate with the water hammer. (3) In a metering stop valve equipped with a disc-shaped valve element, one side of which is seated on an annular valve seat within a valve body having an inlet and an outlet, the flow is controlled by the valve element seated on the valve seat. a valve body installation chamber isolated from both the inlet and the outlet; an activation opening bored in the valve body so as to communicate the valve body installation chamber and the outlet; and a valve in the valve body. A starter valve that can be seated from the body installation chamber side to close the opening; an elastic body that urges the starter valve in the seating direction; and a small hole that communicates the valve body installation chamber and the inlet. , and a metering stop having a water hammer reduction structure, wherein the valve body installation chamber is expanded so that when the valve body is not seated, it goes around the side peripheral surface of the valve body and communicates between one side and the other side. Water faucet.
