Abstract
A kind of Railway passenger train brake alarm valve, comprises main piston, criss-cross pull bar, stage clip, handle, throttling plug, valve body, extension spring, main piston is provided with rubber seal and valve body constitutes primary valve; Main piston and criss-cross pull bar are rigidly connected, and the two is equipped with intercommunicating pore, and criss-cross pull bar is in the guide groove of valve body, can slide up and down along guide groove; Establish stage clip above criss-cross pull bar, handle is fixed on valve body, can rotate around the axis, and handle adopts sliding pair to be connected with between criss-cross pull bar, and throttling plug is arranged on the exhaust outlet of valve body, and extension spring connects handle and valve body.The piston structure with intercommunicating pore that the present invention adopts and the structure by changing different size throttling plug change air draft latus rectum, can according to the speed air draft of demand, thus only trigger other service braking of a specific order, can alleviate at any time can play simultaneously and inform that driver has the effect of emergency situation, meet the operating needs of passenger train.
Description
Technical field
The invention belongs to passenger train braking technology field, relate to a kind of brake alarm valve.
Background technology
In the railway carriage passenger compartment of China, maneuverable position is provided with emergency brake valve, this valve is connected on the train pipe of control train braking, after bus attendant operation, the air of train pipe is emptying by big orifice exhaust outlet valve being fixed specification, triggers train emergency braking.
Emergency brake valve on existing passenger train, owing to being arranged on maneuverable position in guest room, has the risk of passenger's maloperation, thus causes train non-normal stop, affects normal operation.Because emergency brake valve uses rear train to stop rapidly, this action cannot be ignored or alleviate, and train operator cannot adopt an effective measure and avoid train to rest in some special sectors affecting salvage work as bridge, tunnel etc., makes salvage work may be difficult to launch.If also have compartment in passenger train operation process to be in an emergency (as fire etc.), process of must stopping immediately.If but driver can not get the information in the very first time, just brake operating cannot be taked immediately, thus cause the emergency situation occurred in compartment not process in time, have endless trouble.
Summary of the invention
The object of this invention is to provide a kind of brake alarm valve, according to the speed air draft of demand, thus only can trigger other service braking of a specific order, can alleviate at any time can play simultaneously and inform that driver has the effect of emergency situation, meet the operating needs of passenger train.
For achieving the above object, the invention provides a kind of Railway passenger train brake alarm valve, it is characterized in that: comprise main piston, criss-cross pull bar, stage clip, handle, throttling plug, valve body, extension spring, main piston is provided with rubber seal and valve body constitutes primary valve; Main piston and criss-cross pull bar are rigidly connected, and the two is equipped with intercommunicating pore, and criss-cross pull bar is in the guide groove of valve body, can slide up and down along guide groove; Establish stage clip above criss-cross pull bar, handle is fixed on valve body, can rotate around the axis, and handle adopts sliding pair to be connected with between criss-cross pull bar, and throttling plug is arranged on the exhaust outlet of valve body, and extension spring connects handle and valve body.
The piston structure with intercommunicating pore that the present invention adopts and the structure by changing different size throttling plug change air draft latus rectum, when not pulling handle, under the elastic force effect of stage clip, criss-cross pull bar and main piston are pressed on valve body, rubber seal on main piston and valve body are fitted closely, close primary valve, have blocked the path of ventilation inlet to exhaust outlet, air in train pipe cannot be discharged from here, and brake alarm valve is in non-mode of operation.When pulling handle, handle upwards mentions criss-cross pull bar, and open primary valve, the air of train pipe, through ventilation inlet, primary valve, is discharged from throttling plug.According to the speed air draft of demand, thus only can trigger other service braking of a specific order, can alleviate at any time can play simultaneously and inform that driver has the effect of emergency situation, meet the operating needs of passenger train.Because the throttling plug exhaust outlet chosen is all less, the speed of air draft is lower, is not enough to trigger emergency braking, therefore train will produce other service braking effect of a specific order according to exhaust outlet size.And when needing the brake action cancelling train, can unclamp handle at any time, shake hands to reset under the effect of extension spring, primary valve is closed again by said process, make train pipe stop air draft, train braking is alleviated, and brake action is cancelled.
Accompanying drawing explanation
Fig. 1 is lateral plan of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the birds-eye view of Fig. 2.
Detailed description of the invention
With reference to Fig. 1,2, embodiment of the present invention comprises main piston 4, criss-cross pull bar 3, stage clip 10, handle 1, throttling plug 5, valve body 6, extension spring 2, is provided with rubber seal 8, constitutes primary valve with valve body 6 as on the main piston 4 of core functional components; Main piston and criss-cross pull bar 3 are rigidly connected, and can move thereupon, and the two is equipped with intercommunicating pore 9, prevent main piston 4 and criss-cross pull bar about 3 mineralization pressure poor, affect normal function.Criss-cross pull bar is in the guide groove of valve body 6, can slide up and down along guide groove; O-ring seals 11 is installed between this guide groove and criss-cross pull bar, leaks out when avoiding criss-cross pull bar to slide; Establish stage clip 10 above criss-cross pull bar, criss-cross pull bar and main piston can closely be pressed on valve body by its elastic force, and primary valve is closed.Handle 1 is fixed on valve body by a rotating shaft, and can rotate around the axis, adopt sliding pair to be connected between its with criss-cross pull bar, after pulling handle, under the effect of sliding pair, criss-cross pull bar can upward movement.Throttling plug is divided into different size according to the size of exhaust outlet on it, is arranged on the exhaust outlet of valve body by screw thread, can dismounting and change.After installing throttling plug, the air draft ability of path only depends on the size of exhaust outlet on this plug, can be reached the requirement of the different ventilation velocity of brake alarm valve by the throttling plug changing different size.Extension spring 7 connects handle and valve body, for providing restoring force for handle, can automatically reset.
During use, throttling plug instrument screws in valve body.After brake alarm valve installs, ventilation inlet 7 is connected on train pipe.When not pulling handle, under the elastic force effect of stage clip, criss-cross pull bar and main piston are pressed on valve body, rubber seal on main piston and valve body are fitted closely, close primary valve, blocked the path of ventilation inlet to exhaust outlet, the air in train pipe cannot be discharged from here, and brake alarm valve is in non-mode of operation.When pulling handle, handle upwards mentions criss-cross pull bar, and open primary valve, the air of train pipe, through ventilation inlet, primary valve, is discharged from throttling plug.Because the throttling plug exhaust outlet chosen is all less, the speed of air draft is lower, is not enough to trigger emergency braking, therefore train will produce other service braking effect of a specific order according to exhaust outlet size.And when needing the brake action cancelling train, can unclamp handle at any time, shake hands to reset under the effect of extension spring, primary valve is closed again by said process, make train pipe stop air draft, train braking is alleviated, and brake action is cancelled.
