  • Patent number: 8403005
    Abstract: A single-levered rotary pulling tap is used in the kitchen and includes a tap body, a spraying head, a control valve set, a first flowing assembly, and a second flowing assembly used to rotate relative to the first flowing assembly at a predetermined angular range so that user can adjustably move the spraying head to a desired position based on demand, and the pulling tap is operated smoothly to prevent from wearing related parts of the single-levered rotary pulling tap, such as the first flowing assembly, the second flowing assembly, and the control valve set, prolonging service life of the single-levered rotary pulling tap.

  • Publication number: 20120138177
    Abstract: A mixer faucet includes a faucet fixed to a fixing board in a wall and a temperature control valve is connected to the temperature control valve seat. Two check valves are connected to the check valve seats of the cold and hot water paths of the faucet. An indication board is connected to the faucet and seals an installation hole in the wall. The indication board has two access holes which are located corresponding to the check valves. The check valve seats each have a reception recess and the two respective reception recesses are oriented inclinedly and outward. A water inlet is defined between each of the reception recesses and an installation recess of each of the temperature control valve seats. The faucet can be made by way of forging and machined after being forged. The maintenance to the check valves is convenient.
