Abstract
The invention discloses a kind of Pneumatic brake systems punishment brake unit, socket cock including 8# electric pneumatic valve, 1#, 1# electric pneumatic valve, 2# socket cock and equalizing reservoir, two branch roads are had on the air inlet pipeline of described equalizing reservoir, it is respectively path one and path two, described 8# electric pneumatic valve and 1# socket cock and are connected in parallel on path one, and 8# electric pneumatic valve is also by induced duct external guide wind regime, described path two is connected in series 2# successively on pipeline after picking out from the air inlet pipeline of equalizing reservoir and sockets cock and 1# electric pneumatic valve.The invention has the beneficial effects as follows: two master unit electric pneumatic valves use common electric pneumatic valve, low price, simple in construction, change easily；After 8# electric pneumatic valve damages, if temporarily there is no member replacing, cock can be socketed with manually opened 1#, changing path, do not affect.
Description
Technical field
The present invention relates to diesel locomotive control system technical field, particularly a kind of Pneumatic brake systems punishment brake unit.
Background technology
The Pneumatic brake systems of diesel locomotive includes punishment braking action.The principle of punishment braking action is: during locomotive operation, in the case of driver is unwary, and corresponding warning flute can send high pitch warning.If driver does not takes appropriate measures, then punishment brake unit will play a role, and is discharged by equalizing reservoir pressure air, makes train force braking, it is ensured that runs safety.
From the point of view of the most at present, the domestic Pneumatic brake systems used by diesel locomotive, part is the 26-L brakes introduced from the U.S..Use through after a while, think that the punishment brake unit in US Air air braking system has the following disadvantages:
1, the P-2-A mechanical valve structure used is complicated, and in whole punishment brake unit, stringing is the most complicated, and the weight of whole device is the most heavier；
2, being monopolized by the other side due to technology, therefore import cost is the highest；
3, the control time of system is fixed value, it is impossible to amendment, very flexible.
Summary of the invention
The goal of the invention of the present invention is: for the problem of above-mentioned existence, after the principle of profound understanding punishment braking, independent research, it is provided that a kind of Pneumatic brake systems punishment brake unit, structure is simpler, and cost is the lowest.
The technical solution used in the present invention is such that
A kind of Pneumatic brake systems punishment brake unit, socket cock including 8# electric pneumatic valve, 1#, 1# electric pneumatic valve, 2# socket cock and equalizing reservoir, two branch roads are had on the air inlet pipeline of described equalizing reservoir, it is respectively path one and path two, described 8# electric pneumatic valve and 1# socket cock and are connected in parallel on path one, and 8# electric pneumatic valve is also by induced duct external guide wind regime, described path two is connected in series 2# successively on pipeline after picking out from the air inlet pipeline of equalizing reservoir and sockets cock and 1# electric pneumatic valve.
As preferably, described 2# sockets and also sets up a contracting for throttling between cock and 1# electric pneumatic valve and block up.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, two master unit electric pneumatic valves use common electric pneumatic valve, low price, simple in construction, change easily；
2, after 8# electric pneumatic valve damages, if temporarily there is no member replacing, cock can be socketed with manually opened 1#, changing path, do not affect；
3, contracting is stifled acts as a throttle valve, and is controlled exhaust air rate so that it is exhaust air rate is unlikely to excessive thus causes brake hard.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the present invention.
Labelling in figure: 1 is 8# electric pneumatic valve, and 2 socket cock for 1#, 3 is induced duct, and 4 is path one, and 5 is 1# electric pneumatic valve, and 6 is stifled for contracting, and 7 is path two, and 8 socket cock for 2#, and 9 is equalizing reservoir.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in detail.
Embodiment:
As shown in Figure 1, a kind of Pneumatic brake systems punishment brake unit, socket cock 2 including 8# electric pneumatic valve 1,1#, 1# electric pneumatic valve 5,2# socket cock 8 and equalizing reservoir 9, two branch roads are had on the air inlet pipeline of described equalizing reservoir 9, it is respectively path 1 and path 27, described 8# electric pneumatic valve 1 and 1# sockets cock 2 and is connected in parallel on path 1 and 8# electric pneumatic valve 1 is also by induced duct 3 external wind source, and described path 27 is connected in series 2# successively on pipeline and sockets cock 8 and 1# electric pneumatic valve 5 after picking out from the air inlet pipeline of equalizing reservoir 9.
Described 2# socket also set up between cock 8 and 1# electric pneumatic valve 5 one for throttling contracting block up 6.
The model that 8# electric pneumatic valve 1 uses is H23WT-L9-B-00, for normally open valve.The model that 1# electric pneumatic valve 5 uses is FK1BM, for normally close valve.1# electric pneumatic valve 5 electric time length, can modify by microcomputor program, i.e. need to adjust air-bled time, punish braking time and brake pressure according to user；
The action principle of the present invention: during vigilant effect, 8# electric pneumatic valve 1 obtains electric, and path 1 is just disconnected, and equalizing reservoir 9 is the most no longer filled wind.Meanwhile, 1# electric pneumatic valve obtains electric 30s, connects path 27, and the pressure air in equalizing reservoir 9 is discharged by 1# electric pneumatic valve 5, thus plays braking action.
1# sockets cock 2 and 2# and sockets cock 8 vigilant electric pneumatic valve in locomotive operation and break down, can be with manually opened 1# and close 2# and socket cock 8, the directly vigilant braking function of excision, and maintenance locomotive is properly functioning.
8# electric pneumatic valve fills comb by equalizing reservoir and is connected with brakes 15#, and in time watching out for, blocking equalizing reservoir fills the comb UNICOM to equalizing reservoir, directly equalizing reservoir is carried out air draft when 1# electric pneumatic valve is used for watching out for.Master unit electric pneumatic valve uses domestic part to replace former imported mechanical valve, low price, and after breaking down, maintenance is convenient.As electric pneumatic valve vigilant in locomotive operation breaks down, can open 1# and socket cock 2 and close 2# and socket cock 8, the directly vigilant braking function of excision, maintenance locomotive is properly functioning.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
