    Abstract: A pipe adapter may comprise a main body, an O-ring, a conical ring, an engaging ring, a control unit and a locating, tube, and a front opening formed at a front end of the main body which is configured to receive a pipe. Since the conical ring, engaging ring and locating tube are coupled in sequence instead of covering one by one such that there is no need to enlarge a diameter of the front opening of the main body for receiving the above components thereby lowering the manufacturing cost.

    Abstract: A switch valve includes a valve seat, a valve body, a ceramic plate unit, a control shaft, and a control handle. Thus, the ceramic plate unit is rotatable in the valve body to open or close the water flow so that the valve body will not rub the valve seat constantly to prevent the valve body and the valve seat from being worn out due to the friction, thereby enhancing the lifetime of the switch valve. In addition, the ceramic plate unit has a wear resisting function to prevent a gap from being formed between the ceramic plate unit and the valve body during a long-term utilization, so that the ceramic plate unit has a leakproof function, thereby enhancing the working efficiency of the switch valve.

    Abstract translation: 开关阀包括阀座，阀体，陶瓷板单元，控制轴和控制手柄。 因此，陶瓷板单元可以在阀体中旋转以打开或关闭水流，使得阀体不会不断地摩擦阀座以防止阀体和阀座由于摩擦而磨损，从而 提高开关阀的使用寿命。 此外，陶瓷板单元具有耐磨功能，以防止在长期使用期间在陶瓷板单元和阀体之间形成间隙，使得陶瓷板单元具有防漏功能，从而增强了加工 切换阀的效率。

    Abstract: A structure is designed to switch the flow of fluid in a fluid conveying system. The structure includes two fluid-discharging pipes connected one to end, a valve slot formed at the juncture of the two fluid-discharging pipes, a fluid-admitting pipe fastened to the valve slot, and a ball valve rotatably disposed in the valve slot such that the ball valve can be turned by a valve knob to control the flow of fluid into the two fluid-discharging pipes from the fluid-admitting pipe.
