The invention relates to a purge valve, an air drying device, a system based on pressurized air and a commercial vehicle. A purge valve (100) with an integrated safety function is suitable for an air drying device. In a purge valve, a purge valve body (102) forms a first exhaust passage (104) for connecting an inlet line (101) to an outlet line (103). A purge valve piston (108) is disposed within the purge valve body to control exhaust flow through the first exhaust passage upon receipt of a purge signal (S). The purge valve piston includes a through opening (110) configured to form a second exhaust passage (112) for connecting the inlet line to the outlet line. A valve member (114) is disposed in the through opening and is configured to control exhaust flow through the second exhaust passage (112). The valve member is configured to be actuated by the pressurized air when a pressure value in the inlet line exceeds a threshold actuation pressure.
本发明涉及一种净化阀、空气干燥装置、基于加压空气的系统和商用车辆。具有集成安全功能的净化阀(100)适用于空气干燥装置。在净化阀中,净化阀体(102)形成用于将入口管线(101)连接到出口管线(103)的第一排气通道(104)。净化阀活塞(108)布置在净化阀体内以在接收到净化信号(S)时控制通过第一排气通道的排气流。净化阀活塞包括贯通开口(110),该贯通开口(110)被构造成形成第二排气通道(112),用于将入口管线连接到出口管线。阀构件(114)布置在贯通开口中并且被构造成控制通过第二排气通道(112)的排气流。阀构件被构造成当入口管线中的压力值超过阈值促动压力时由加压空气促动。
