Patent number: 10801656Abstract: A pressure reducing valve may include a valve body, a connecting tube, and a pressure-reducing member. The valve body is a three-way intercommunicated valve body which respectively forms into a water inlet end, a water outlet end, and a pressure-reducing tube. The connecting tube is connected to an extending section thereof, and at least a first annular groove is formed at an outer periphery of the extending section for disposing an O-ring thereon. An annular surface formed between the connecting tube and the extending section is faced to the extending section. The pressure-reducing member is hollow and has a closed end and an open end, and a buffer block is installed therein. The open end is abutted against the annular surface of the extending section, and a coupled portion between the open end and the annular surface is welded together to form a welding portion therebetween.Type: GrantFiled: December 4, 2018Date of Patent: October 13, 2020Inventor: Hung-Lin Lai

Publication number: 20200025297Abstract: A water control valve may comprise a main body, a valve core, a sealing unit and a handle. The main body has a valve chamber to accommodate the valve core, and a first tube portion and a second tube portion are respectively extended from two sides of the valve chamber. The main body has a protruding portion formed at an outer periphery thereof, and a first through hole is adapted to vertically penetrate through the protruding portion to communicate with the valve chamber. The sealing unit is formed integrally to have a connecting portion, and a flexible sealer is formed at the outer periphery of the connecting portion. In present invention, the weight of the water control valve is reduced and the sealing unit can be easily pressed into the first through hole, to limit the position of the valve core and achieve the sealing effect.Type: ApplicationFiled: July 17, 2018Publication date: January 23, 2020Applicant: WEN SHENG FU CO., LTD.Inventor: Hung-Lin LAI

Patent number: 7802590Abstract: 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.Type: GrantFiled: March 16, 2007Date of Patent: September 28, 2010Assignee: Wen Shen Fu Co., Ltd.Inventor: Hung-Lin Lai
