A distribution valve for a sink is provided to connect many water supply pipes regardless of a space at the bottom of a sink by connecting many distribution valves simply, and a stop cock for water supply is provided to cut down on the cost and to contribute to improvement of productivity by having an absorber connection for fastening a hammer absorber integrally and to construct conveniently and safely by having an instrument holder for holding an instrument and installing a water supply pipe. A distribution valve for a sink is divided into a main valve(100) and a sub valve(200). The main valve comprises a main body(110) provided with a main flow passage(112) for fluids flowing inward, a multiple connection(114) extended at the top and a fastening groove connected with the main flow passage, a union fastener connected to the inner circumferential surface of the lower part of the main flow passage of the main body and provided with a flow passage and a support projection, and a union(120) fastened to the main body by the union fastener and provided with a limit mounted on the support projection of the union fastener and a thread, wherein a first O-ring is formed on the lower part of the union fastener to prevent a leakage of water, and a second O-ring is formed between the fastening groove of the main body and a first fastening joint of a sub body to prevent a leakage of water. The sub valve comprises a sub body(210) provided with a sub flow passage for fluids flowing inward, a first fastening joint fastened to the fastening groove of the main body, an outlet(214) fitted with a supply pipe, a second fastening joint fastened with a pipe fastener(220) to fix the supply pipe fitted to the outlet, an opening and closing device and a stopper projection(213), and a control device(230) operating together with the opening and closing device of the sub body and controlling the opening and closing device. A stop cock for water supply comprises a body including a water supply pipe connection connected with a water supply pipe, an opening and closing handle controlling the flow of fluids and an upper connection connected with a distribution valve or a tap, wherein an absorber connection is formed on the body to connect a water hammer absorber for absorbing shock caused by water pressure of fluids flowing in the water supply connection, and an instrument holder is formed on the outer circumferential surface to rotate and install the body of the stop cock to the water supply pipe. |
