Abstract
The utility model discloses a pressure indicator, which comprises a casing and a valve. The casing and the valve are fixed through screws, and a valve end cover is arranged at the upper end of the valve. The pressure indicator is characterized in that a view window is arranged on the casing, a pressure device arranged in the valve consists of a piston rod and a piston, a movable colored plate is integrally arranged at the upper end of the piston rod, and a spring is arranged on the pressure device. The pressure indicator has the advantages that when a worker looks into the view window for checking, the pressure of a locomotive is normal if only one color is displayed on the movable colored plate of the pressure indicator, and the pressure of the locomotive is insufficient if two different colors are displayed on the movable colored plate of the pressure indicator. Since the locomotive requires sufficient pressure for enough braking force, a driver can be reminded of potential faults of the locomotive when the pressure of the locomotive is insufficient, faults can be timely checked out and the locomotive can be timely maintained by the worker, and accident rate is decreased.
Description
Technical field
The utility model relates to a kind of pressure indicator.
Background technology
Rolling stock now can't foresee when running into locomotive problem is arranged in the process of moving in advance, and so just have a lot of accidents and produce, gently then by the time maintenance is investigated at the station again, heavy then threat to life safety in the process of moving.
Summary of the invention
The utility model technical matters to be solved provides a kind of pressure indicator that when vehicle has fault, can warn.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of pressure indicator, comprise shell and valve body, and described shell and described valve body pass through screw retention; Described valve body upper end is provided with valve body end cap; It is characterized in that described shell is provided with form, be provided with pressure apparatus in the described valve body, described pressure apparatus is made up of piston rod and piston; Described piston rod upper end has been wholely set mobile colour table, and described pressure apparatus is provided with spring;
Described spring upper end is connected with described valve body end cap, and the lower end is connected with described piston;
Be provided with the piston envelope between described piston and the described valve body,
Described mobile colour table is provided with two kinds of colors.
Compared with prior art, the utility model has the advantages that when the staff checks through form, if the mobile colour table on the pressure indicator only shows a kind of color; Explain that locomotive pressure is normal,, explain that locomotive pressure is not enough if the mobile colour table on the pressure indicator shows two kinds of different colours; And locomotive must have enough pressure that enough braking forces just can be arranged; Since locomotive pressure is not enough, so just can watchful driver, locomotive possibly be out of order; The staff can investigate and maintenance failure timely, has reduced the incidence of accident.
Description of drawings
Fig. 1 is the structural representation of the utility model;
The title of above accompanying drawing and sequence number: 1, shell, 2, valve body, 3, valve body end cap, 4, piston, 5, piston rod, 6, form, 7, move colour table, 8, spring, 9, the piston envelope, 10, screw.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Case study on implementation: a kind of pressure indicator, comprise shell 1 and valve body 2, shell 1 is fixing through screw 10 with valve body 2; Valve body 2 upper ends are provided with valve body end cap 3, and shell 1 is provided with form 6, are provided with pressure apparatus in the valve body 2; Pressure apparatus is made up of piston rod 5 and piston 4, and piston rod 5 upper ends have been wholely set mobile colour table 7, moves colour table 7 and is provided with two kinds of colors; Pressure apparatus is provided with spring 8; Spring 8 upper ends are connected with valve body end cap 3, and the lower end is connected with piston 4, are provided with piston envelope 8 between piston 4 and the valve body 2;
When pressurized air gets in the valve body 2 by admission port, up push up behind piston 4 pressurizeds always, promote piston rod 5 and also up push up always; When piston rod 5 pushes up the valve body end cap 3 of top, when seeing through form 6, if move on the colour table 7 independent a kind of color has appearred; Explain that the locomotive upward pressure is normal; Two kinds of different colours having occurred if move on the colour table 7, explained that the locomotive upward pressure is not enough, possibly be that fault has appearred in locomotive.
