    摘要： A high-pressure gas cylinder valve for vehicle includes a valve seat. The valve seat is provided with a gas charging runner and a gas supplying runner. A check valve (401) is connected in series onto the gas charging runner, and the check valve and a solenoid valve (601) are connected in series sequentially onto the gas supplying runner in a gas flow direction. A portion of the gas supplying runner located downstream of the solenoid valve (601) is jointly connected to a portion of the gas charging runner adjacent to a gas inlet end and supplies gas to outside through a gas inlet of the gas charging runner when the gas supplying runner supplies gas. The gas cylinder valve further includes a flow-blocking buffer structure, and the flow-blocking buffer structure is connected in series onto the gas supplying runner and is located downstream of the solenoid valve (601) and upstream of an intersection of the gas supplying runner and the gas charging runner. Through arrangement of the flow-blocking buffer structure, when the gas is charged into the gas cylinder through the gas charging runner, the high-pressure gas flowing into the gas supplying runner is blocked by the flow-blocking buffer structure. The solenoid valve (601) is prevented from being impacted by the high-pressure gas, the solenoid valve (601) is therefore prevented from being damaged, and the reliability and safety of the gas cylinder valve are improved.

    摘要： A filtration system is disclosed, which comprises a filtration-element within a filtration chamber, and a valving device located exteriorly to the filtration chamber, for reversing the direction of fluid-flow through the filtration-element for backwashing. The valving device thus functions as a common valve for handling both filtration and backwash. The common valve is based on a linearly-movable plug located inside a valve housing which is communicable with the filtration chamber, with a source of fluid to be filtered, and with evacuation port for backwash fluid, through three respective openings in the valve housing, and is characterized by an uninterrupted bend-free flow-channel extending at least from exteriorly to an inlet opening of the valve housing, to the body of the filtration-element whenever the common valve is in a filtration mode of operation.

    摘要： The present invention discloses a five-way valve, wherein the five-way valve comprises a valve body provided with a water inlet, a first water outlet, a second water outlet, a third water outlet and a pressure relief opening which are communicated with an interior of the valve body successively from top to bottom; a movable element assembly and a sealing ring assembly which are respectively configured to control the opening and closing of each water outlet are provided inside the valve body; and the sealing ring assembly is fixedly mounted on the movable element assembly, and a bottom end of the movable element assembly is abutted against an inner side of a bottom end of the valve body by elastic elements. With regard to the five-way valve in the present invention, two chambers are formed in the valve body by the arrangement of the movable elements, and by different water flow pressures in the valve body, the introduction of pressure into two piston chambers can be controlled at different time; and the pressures in the two chambers can be relieved successively from a same outlet after the water feed and pressure supply is stopped. The five-way valve can be used to replace the electromagnetic valve, and it can control the successive flowing of water into or out of the two water outlets and also the communication between all water inlets and outlets. The five-way valve is simple in structure, low in manufacturing cost and more convenient for application and popularization.
