Abstract
The utility model relates to a safe energy-saving electric pneumatic valve for a locomotive, in particular to a safe energy-saving electric pneumatic valve for a 24V locomotive. The safe energy-saving electric pneumatic valve is obtained by improving the conventional electric pneumatic valve, namely the direct-current rated voltage of the electric pneumatic valve is 24V, and the winding number of an electromagnetic coil of the electric pneumatic valve is only 3,300 and is 10,000 lower than that of the common electric pneumatic valve; the diameter of the electromagnetic coil is changed from 0.23 millimeter to 0.43 millimeter; the weight of the electromagnetic coil is only 75 percent of the original weight; a movable iron core is machined into a 45-degree conical structure, so that the intensity of magnetic field is improved, the overall size of the electric pneumatic valve is reduced, the performance is improved, the using performance of the electric pneumatic valve under different voltages is met, and the using range of the electric pneumatic valve is enlarged; and because the winding number of the electromagnetic coil is lower than that of the common electric pneumatic valve, the manufacturing cost of related parts is greatly reduced, and the electric pneumatic valve has obvious economic benefits.
Description
Technical field
The utility model relates to a kind of locomotive and uses the safety and energy-saving electric pneumatic valve, and particularly the 24V locomotive is used the safety and energy-saving electric pneumatic valve, and it is that railway electric locomotive (comprising city rail, subway) is gone up major control parts in the air-path control system.
Background technique
The common voltage rating of using in the existing electric locomotive of electric pneumatic valve is 110V, but along with the development, particularly city trailer car of electric locomotive cause and the manufacturing of underground railway track locomotive, its low voltage control system is constantly development also; Original 110V electric pneumatic valve can not satisfy the demand of city trailer car and the development of underground railway track locomotive.The number of turns of the electromagnetic coil in original 110V electric pneumatic valve is many, and the electric pneumatic valve overall dimensions is big, and manufacture cost is also high.
Summary of the invention
The purpose of the utility model is to the problems referred to above; The locomotive that provides a kind of and reduced the electric pneumatic valve overall dimensions, reduces manufacture cost is used the safety and energy-saving electric pneumatic valve; Thereby under the prerequisite that guarantees the electric pneumatic valve control performance, satisfy the demand of city trailer car and underground railway track locomotive development.
The technological scheme of the utility model: a kind of locomotive is used the safety and energy-saving electric pneumatic valve; Comprise dust-proof cover, yoke tube, moving iron core, copper tube, electromagnetic coil, static iron core, core bar, screw, spring pad, wire board, metal seat valve, valve rod, stopper, O shape circle, recovery springs, lower valve, go up valve and rubber pad; The number of turns that it is characterized in that described electromagnetic coil is 3300 circles; The line of this electromagnetic coil directly is 0.43 mm, and moving iron core is 45 degree cone structures.
The utility model is on the basis of existing electric pneumatic valve, to improve, and promptly the dc rated voltage of electric pneumatic valve is 24V, and the number of turns of its electromagnetic coil has only 3300 circles, has lacked 10000 multiturns than the number of turns of common electric pneumatic valve; 0.43 mm is changed into by 0.23 mm in the line footpath of electromagnetic coil; The weight of its electromagnetic coil 5 has only 75% of original weight; Moving iron core is processed into 45 degree cone structures, strengthens magnetic intensity, has reduced the electric pneumatic valve overall dimensions, improved performance, has satisfied the usability that different electric is depressed electric pneumatic valve, has enlarged the using scope of electric pneumatic valve; Because the number of turns of electromagnetic coil lacks than the number of turns of common electric pneumatic valve, has practiced thrift the manufacture cost of associated components in a large number, has tangible economic benefit.
Description of drawings
Accompanying drawing is the structural representation (dead electricity normally off) of the utility model;
Among the figure: the 1-dust-proof cover, 2-yoke tube, 3-moves iron core, 4-copper tube, 5-electromagnetic coil, 6-static iron core; The 7-core bar, 8-screw, 9-spring pad, 10-wire board, 11-metal seat valve, 12-valve rod; The 13-stopper, 14-O shape circle, 15-recovery springs, 16-lower valve, the last valve of 17-, 18-rubber pad.
Embodiment
Referring to accompanying drawing; A kind of locomotive is used the safety and energy-saving electric pneumatic valve; Comprise dust-proof cover 1, yoke tube 2, moving iron core 3, copper tube 4, electromagnetic coil 5, static iron core 6, core bar 7, screw 8, spring pad 9, wire board 10, metal seat valve 11, valve rod 12, stopper 13, O shape circle 14, recovery springs 15, lower valve 16, go up valve 17 and rubber pad 18; The number of turns that it is characterized in that described electromagnetic coil 5 is 3300 circles; The line of this electromagnetic coil 5 directly is 0.43 mm, and moving iron core 3 is 45 degree cone structures.
Shown position is that the safety and energy-saving electric pneumatic valve is in the dead electricity normally off, and this moment, recovery springs 15 was in compressive state, makes the lower valve 16 and the valve port of metal seat valve 11 keep good sealing.When the safety and energy-saving electric pneumatic valve get electric after; The electromagnetic force that electromagnetic coil 5 produces promotes moving iron core 3 and moves down; Thereby promotion core bar 7, last valve 17, valve rod 12, lower valve 16 move down; And then open lower valve 16, and closing the stem travel (δ A) of closing valve 17, pressurized gas carry out work through the actuator that the lower valve of opening 16 gets into control section.Work as powered-down, then go up valve 17 close port under the effect of recovery springs 15, stop air inlet, actuator then quits work.
The utility model is used the safety and energy-saving electric pneumatic valve for the 24V locomotive, and difference from prior art is main is that the number of turns of electromagnetic coil 5 has only 3300 circles, has lacked 10000 multiturns than the number of turns of common electric pneumatic valve; 0.43 mm is changed into by 0.23 mm in the line footpath of electromagnetic coil; The weight of its electromagnetic coil 5 has only 75% of original weight; Moving iron core 3 is processed into 45 degree cone structures, strengthens magnetic intensity.
