Abstract
The utility model relates to a locomotive parking and braking safety cutoff device, which comprises a two-way solenoid valve, a two-way comparison valve, a main air pressure switch and a cutoff electric control valve, wherein the air inlet of the two-way solenoid valve is connected with a main air pipe, the air outlet of the two-way solenoid valve is connected to the two-way comparison valve through a pipeline, the air outlet of the two-way comparison valve is connected with a parking pipe, the main air pressure switch is arranged on a connecting pipeline between the two-way solenoid valve and the two-way comparison valve, the air inlet of the cutoff electronic control valve is connected with a braking cylinder pipe, the air outlet of the cutoff electronic control valve is connected to the two-way comparison valve through a pipeline, and the main air pressure switch controls the cutoff electronic valve to be powered-on or powered-off. Therefore, the locomotive parking and braking safety cutoff device can automatically control the connection and disconnection of the braking cylinder pipelines in the parking and braking device, and prevents the pressure of the braking cylinder from having abnormal changes to threaten the safety of driving.
Description
Technical field
The utility model relates to the railway rolling stock brake control system, refers to a kind of device that is used for controlling machine car spring accumulation of energy stopping brake especially, is specifically related to a kind of locomotive parking brake safety cutoff.
Background technology
Domestic railway locomotive substantially all is equipped with the spring energy-storage stop device at present, for avoiding locomotive at glancing impact, air brake and parking brake produce stack makes locomotive brake force excessive, cause that brake equipment or associated components damage, this parking brake device is provided with the two-way relatively valve that is used for more total wind pressure and brake-cylinder pressure size, as shown in Figure 1, and be provided with bidirectional electromagnetic valve and state and show pressure switch, blocking plug door and park parts such as pipe.Yet, since two-way relatively valve be prone to collaborate, gas leak phenomenon, thereby cause brake-cylinder pressure to change not having under the control, threaten traffic safety.
Summary of the invention
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, a kind of locomotive parking brake safety cutoff is provided, this device can be controlled the break-make of brake cylinder pipeline in the parking brake device automatically, avoid brake-cylinder pressure under the nothing control, to change, threaten traffic safety.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of locomotive parking brake safety cutoff comprises bidirectional electromagnetic valve, reaches two-way relatively valve; The ventilation inlet of this bidirectional electromagnetic valve is connected with blast main, and air outlet is connected to two-way relatively valve by pipeline; The air extractor duct of two-way relatively valve with park pipe and be connected, be characterized in: this device also comprises total wind pressure switch, reaches and interdict electrically-controlled valve, this total wind pressure switch is installed on bidirectional electromagnetic valve and the two-way connecting line that compares between the valve; The ventilation inlet of this blocking electrically-controlled valve is connected with the braking earthen pipe, and air outlet is connected to this two-way relatively valve by pipeline; Electric and the dead electricity that gets of electrically-controlled valve is interdicted in this total wind pressure switch control.
Described blocking electrically-controlled valve is for often opening electrically-controlled valve.The pressure of described total wind pressure switch is set to 5bar.
Compared with prior art, the utility model has the advantages that: this device can be controlled the break-make of brake cylinder pipeline in the parking brake device automatically, make locomotive under running state, effectively avoid because the two-way relatively fault of valve causes the pressurized air of brake cylinder pipeline to leak; Effectively avoid fault owing to two-way relatively valve to cause the pressurized air of the pressurized air on blast main road and brake cylinder pipeline to gang up the brake-cylinder pressure that causes and under no control state, change, improved the safe reliability of locomotive parking brake device.
Description of drawings:
Fig. 1 is the control scheme drawing of known parking brake device.
Fig. 2 is a parking brake safety cutoff control scheme drawing of the present utility model.
The specific embodiment:
Referring to Fig. 2, the utility model is a locomotive parking brake safety cutoff, this device comprises bidirectional electromagnetic valve 1, two-way relatively valve 2, total wind pressure switch 3, blocking electrically-controlled valve 4 etc., the ventilation inlet of bidirectional electromagnetic valve 1 is connected with blast main, air outlet is connected to two-way relatively valve 2 by pipeline, on bidirectional electromagnetic valve 1 and the two-way connecting line that compares between the valve 2, total wind pressure switch 3 is installed, the ventilation inlet of blocking electrically-controlled valve 4 is connected with the braking earthen pipe, air outlet is connected to two-way relatively valve 2 by pipeline, the air extractor duct of two-way relatively valve 2 connects parks pipe, and blocking plug 5 is installed on two-way relatively valve 2 and the pipeline of parking between the pipe, state pressure switch 6 and state pressure switch 7.
Wherein, blocking electrically-controlled valve 4 is for often opening electrically-controlled valve, and the pressure of total wind pressure switch 3 is set to 5bar.Electric and the dead electricity that gets of electrically-controlled valve 4 is interdicted in one road open contact control of total wind pressure switch 3.When the compressed air pressure at total wind pressure switch 3 places during less than 5bar, blocking electrically-controlled valve 4 be a power failure state, and blocking electrically-controlled valve 4 is communicated with the air flue between brake pipings and the two-way comparison valve 2; When the compressed air pressure at total wind pressure switch 3 places during more than or equal to 5bar, the blocking electrically-controlled valve 4 be electricity condition, blocking electrically-controlled valve 4 disconnects, close brake cylinder pipeline and the two-way relatively air flue between the valve 2, at this moment, the pressurized air in the blast main enters and parks pipe through two-way relatively valve 2, blocking plug door 5.
