Abstract
The utility model discloses a full-function JZ-7 type brake testing bed which pertains to the technical field of tests and detection of locomotive valves, and mainly solves the problem that the existing JZ-7 type brake testing bed can not conduct single-valve tests or comprehensive tests on cut control valves or double linking valves. The full-function JZ-7 type brake testing bed is mainly characterized in that a cut control valve seat and a double linking valve seat are additionally arranged on the basis of the existing JZ-7 type brake testing bed which comprises a brake valve seat, an air relay valve seat, a relay valve seat, a blast interceptor valve seat, a main valve seat, an auxiliary valve seat, an emergency calve seat and a power system, wherein the cut control valve seat is connected with the main valve seat, the auxiliary valve seat, the emergency valve seat, a dust filter and a blast cylinder respectively through blast pipes and electric control valves; and the double linking valve seat is connected with the brake valve seat, the blast interceptor valve seat, the relay valve seat and the air relay valve seat respectively through blast pipes and electric control valves. Therefore, the testing condition of a brake system of a locomotive additionally provided with the cut control valve or the double linking valve can be imitated more objectively. The full-function JZ-7 type brake testing bed is characterized by being simple, easy and practical, and is mainly used for inspection tests of the locomotive provided with a JZ-7 brake system.
Description
Technical field
The utility model belongs to the test of locomotive valve class, detection technique field.Be specifically related to a kind of full function brake experimental bench.
Background technology
Traditional JZ-7 brake experimental bench can only satisfy locomotive JZ-7 brake system JZ-7 type brake valve (from valve and single valve), F-7 distribution valve (comprising main valve, secondary valve, emergency vent valve), air relay valve, 104 relay valves, always the wind intercepter valve (IV) is done single valve test and compbined test.Brake experimental bench by stand, be fixed on braking valve seat on the stand, main valve seat, auxiliary-seat, emergency vent valve seat, air servo valve seat, relaying valve seat, total wind blocking valve seat, the power system that constitutes by total reservoir and high-pressure valve, and be connected total reservoir and braking valve seat, distribute valve seat, airduct, electrically-controlled valve and reservoir between air servo valve seat, relaying valve seat, total wind blocking valve seat, effect valve seat, main valve seat, auxiliary-seat and the urgent valve seat.In addition, adopt and to cut control valve testing table and do and cut the test of control valve single valve, adopt JZ-7 double-heading valve testing table to do the test of double-heading valve single valve.Because all valves of existing locomotive JZ-7 brake system need to do the single valve test at three different testing tables, and can not finish all the single valve experiment works of JZ-7 type brake system with a testing table, existence can not do all valve members one compbined test, can not simulate Full Vehicle System work and can not reflect the deficiency of each valve member matching property.
Summary of the invention
The purpose of this utility model is exactly that a kind of simple in structure, global function locomotive brake gear testing table that can satisfy all valves of JZ-7 type brake system test needs on a testing table is provided at above-mentioned weak point.
Technical solution of the present utility model is: a kind of global function JZ-7 type brake experimental bench, comprise stand, be fixed on the braking valve seat on the stand, air servo valve seat, the relaying valve seat, total wind blocking valve seat, main valve seat, auxiliary-seat and urgent valve seat, the power system that constitutes by total reservoir and dust filter, and be connected total reservoir and brake valve seat, main valve seat, auxiliary-seat, air servo valve seat, the relaying valve seat, airduct between total wind blocking valve seat and the urgent valve seat, electrically-controlled valve and reservoir is characterized in that: comprise that also being fixed on cutting on the stand controls valve seat and double-heading valve seat; Wherein, cutting the control valve seat is connected with main valve seat, auxiliary-seat, urgent valve seat, dust filter and total reservoir respectively by airduct, electrically-controlled valve; The double-heading valve seat is connected with braking valve seat, total wind blocking valve seat, relaying valve seat, air servo valve seat respectively by airduct, electrically-controlled valve.
The utility model is cut control valve seat and double-heading valve seat owing to being equipped with on existing locomotive brake gear testing table, and will cut the control valve seat and pass through airduct, electrically-controlled valve respectively with main valve seat, auxiliary-seat, urgent valve seat, dust filter is connected with total reservoir, the double-heading valve seat is passed through airduct, electrically-controlled valve respectively with the braking valve seat, total wind blocking valve seat, the relaying valve seat, air servo valve seat connects, like this, the utility model locomotive brake gear testing table not only keeps satisfying to locomotive JZ-7 brake system JZ-7 type brake valve (from valve and single valve), the F-7 distribution valve, the air relay valve, 104 relay valves are done single valve test and compbined test, and can also satisfy locomotive JZ-7 brake system is cut the control valve, the JZ-7 double-heading valve is done the single valve test, and can do compbined test to all valve members, carry out pipeline control, simulate Full Vehicle System work and each valve member matching property of reflection, finish all JZ-7 type brake system tests.The utlity model has characteristics simple in structure, as on a testing table, to satisfy all valve test needs of JZ-7 type brake system.The utility model is mainly used in all valves of JZ-7 type brake system is carried out single valve test and compbined test.
