Description

A kind of air brake valve for locomotive and using method
Technical field
The present invention relates to the braking technology field, be specifically related to a kind of air brake valve for locomotive.
Background technology
Electropneumatic brake is locomotive braking system a kind of braking model commonly used, DK-1 type locomotive electro-pneumatic brake with China's the seventies in last century development is an example, because of its have the decompression amount accurately, fill advantages such as wind is fast, the brake activation valve bar handle is flexible, noise emission is little, be widely used in the brake system of locomotive at present.
In the locomotive electro-pneumatic brake, air brake valve is its core component.Air brake valve has the two kinds of operating modes in electric room and air position, in electric room, controls braking, pressurize and the alleviation of locomotive separately by the pressure of control action chamber, and this moment, air brake valve played the effect of " little lock "; In the air position, can control braking, pressurize and the alleviation of full train by the pressure of control equalizing reservoir, this moment, air brake valve played the effect of " big lock ".In above-mentioned operating mode, air brake valve has four representative type control positioies, puts in order to be followed successively by by conter clockwise and alleviates position, driving position, neutral position and retarder location.
As shown in Figure 1, be the scheme drawing of the air brake valve in the DK-1 type locomotive electro-pneumatic brake under the prior art.Air brake valve shown in Figure 1 comprise valve body 1 and with valve body bonded assembly cam case 2, in the lower end of cam case, exhaust valve 4 is installed also.
Handgrip axle 101 is installed in cam case 2, handgrip axle 101 is hollow square axle structure, the top of handgrip axle 101 passes cam case and is connected with handle bracket 102, and also location and installation has push rod 103 at handgrip axle 101 centers, is equipped with on the handle bracket 102 and push rod bonded assembly handgrip 102a.The outer cover of the handgrip shaft portion in cam case 2 is equipped with positioning cam 104 and operating cam 105, and described positioning cam 104 is installed in the upside of described operating cam 105.Conversion plunger (not shown), position ram 114, effect plunger 115 are installed in valve body 1; Described conversion plunger can switch between different operating modes by the control air brake activation valve, and described effect plunger 115 is by described operating cam 105 controls, and described position ram 114 is by described positioning cam 104 controls.
For the signal with positioning cam passes to computing machine, the interlocking switch group also is installed in cam case, described interlocking switch group comprises two micro-switchs being controlled by positioning cam and conversion plunger respectively, micro-switch 104a by positioning cam 104 controls can give computing machine with the electric signal transmission of positioning cam, and the micro-switch of being controlled by the conversion plunger (120a) can pass to computing machine with the mode of operation of rotary column plug.
In above-mentioned air brake valve, by rotating described handgrip 102a, can drive 101 rotations of handle bracket 102 control handgrip axles, thereby the positioning cam and the operating cam that drive on the handgrip axle are controlled position ram and effect plunger, to realize that air brake valve is in the switching of alleviating between position, retarder location, neutral position and four control positioies of driving position.When air brake valve is in control position in above-mentioned four control positioies, can give computing machine with the electric signal transmission of positioning cam by the micro-switch of positioning cam control.
Development along with the Heavy-Haul Railway transportation, need control slave locomotive and the run-in synchronism of master control locomotive that whole train is worked smoothly, promptly need slave locomotive action and each control position of master control locomotive be consistent, the action of slave locomotive is generally controlled by the wireless synchronization control system.In existing air brake valve, owing to have only micro-switch of positioning cam control, therefore in four control positioies of air brake valve, can only produce two electric signal at most and pass to the wireless synchronization control system, therefore the wireless synchronization control system of controlling slave locomotive can only receive the working signal of two control positioies of master control locomotive in fact at most, and can not receive the working signal of two other control position of master control locomotive, therefore can not realize the synchronization action of slave locomotive and master control locomotive.
