Line system for fluids having volatile components

A line system (1) for fluids having volatile components, which comprises at least one fluid line (2,3,4), each having a separate inlet (10) and outlet (11), the fluid lines (2,3,4) being enclosed by a first line wall (12) and extending jointly over a section (A) of the line system (1) close-fitting to one another, but being separated from one another at least by the first line wall (12) over the entire length of the fluid lines (2,3,4). The line system (1) is implemented as a plastic hollow profile at least over the section (A) and comprises a further fluid line (8), which is enclosed by a second line wall (13), and comprises one or more line chambers (8″,8′″), which are at least partially separated from one another by support webs (7), whose totality at least essentially encloses the fluid lines (2,3,4). In addition, the first and second line walls (12,13) and the support webs (7) of the plastic hollow profile being implemented from the same polymer material. The line system (1) according to the present invention is characterized in that the further fluid line (8) is implemented as a scavenging line (8) having scavenging chambers (8″,8′″) and is connected to a scavenging device, which is implemented for flushing or suctioning the scavenging line (8) and therefore for conveying away and collecting permeates originating from the fluid lines.

Rapid brake and relieve device and method of parking brake cylinder of fireless loopback locomotive

The invention discloses a rapid brake and relieve device and method of a parking brake cylinder of a fireless loopback locomotive. The parking brake cylinder 10 is connected with one end of a reverse valve 4 through a cock 5 of the parking brake cylinder 10. The other two ends of the reverse valve 4 are connected with a brake 9 and the end a of a bidirectional solenoid valve 3 respectively. The end p of the bidirectional solenoid valve 3 is connected with an air storage cylinder 2 and is further connected with a check valve 1 of a main air cylinder 8. A train pipe 7 is connected with the end p of the bidirectional solenoid valve 3 through a check valve 6 of the train pipe 7. The method includes the step of parking braking, wherein a parking braking action button of a fireless locomotive cab is operated, a port a of the bidirectional solenoid valve 3 is controlled to be communicated with a port 0, compressed air of the parking brake cylinder 10 is exhausted to the atmosphere, and then the parking brake cylinder 10 is at the action state; the step of fireless loopback, wherein the train pipe 7 is communicated with the fireless locomotive, a parking braking relieve button of the fireless locomotive cab is operated, a port p of the bidirectional solenoid valve 3 is controlled to be communicated with the port a, sustained pressure of the train pipe 7 is injected into the parking brake cylinder 10, and then the parking brake cylinder is relieved.
