Furthermore, a manhole 5.14 is fixed at the top of the first cylinder 6.2 or the second cylinder 6.3 and is used for a maintainer to go in and out of the tank body. The traditional railway light oil tank car loads and unloads media through a manhole, so the manhole is always kept in an open state in the loading and unloading process, and medium steam escapes into the air to pollute the environment. The manhole 5.14 of the embodiment is only used for the access of the maintenance personnel to the tank body, and is closed at the rest of time.
Taking the following loading and unloading process as an example, the inclined seat valve joint 5.5 is connected with a loading and unloading oil pipe of the ground facility storage tank, the steam return pipeline joint 5.7 is connected with an air pipeline of the ground facility storage tank, pushing pressure is provided by an air compressor, light oil medium and air (possibly containing light oil medium steam) circularly flow to realize loading and unloading, all accessories in the whole process are kept closed, the medium steam cannot escape, and the medium steam is recovered and kept in the steam return pipeline 5.6 or the tank body after being liquefied and cannot leak.
The bottom valve 5.1, the inclined seat valve 5.4 and the joints thereof, the steam return pipeline joint 5.7, the loading and unloading valve 5.13, the vent valve 5.11 and the manhole 5.14 of the embodiment all belong to the fittings for manually operating opening and closing outside the tank, and are not easy to open or close due to non-human factors, thereby further ensuring the safety of the tank body.
Example two:
the embodiment provides a railway tank car, as shown in fig. 1, the railway tank car comprises a railway tank car body according to the first embodiment, and further comprises a bogie 2, a parking brake device 3 and an air brake device 4, wherein the bogies 2 are mounted at the bottoms of two ends of an underframe assembly 1, and the parking brake device 3 and the air brake device 4 are respectively mounted at the bottom of the underframe assembly 1 through a hanging seat and are located below a first cylinder 6.2 or a second cylinder 6.3.
The coupler buffer device 8 is arranged on the outer side of an end beam of the underframe assembly 1 through a bolt; the walking board assembly 9 is divided into a top walking board, an end walking board and an escalator, the butt joint surfaces of two cylinders of the tank body assembly 6 are superposed with the transverse central surface of the underframe assembly 1, appropriate spaces are reserved for the two ends of the underframe assembly 1, the end walking board of the walking board assembly 9 is welded, and the longitudinal space of the underframe assembly 1 is fully utilized.
And the outer side of one end and the outer side of the top of the tank body assembly 6 are welded with supporting legs for mounting a top walking board and an escalator. This embodiment sets up two signboard assemblies 10, and is central symmetry and arranges, welds in the longitudinal support plate 7.1 outside of jar body support assembly 7 through the landing leg, and the lateral surface spraying of signboard assembly 10 or paste vehicle relevant information, like car number, dead weight, load etc..
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
