Abstract
The invention relates to a sand spray control valve for a locomotive. A valve body is connected to a mounting flange of the locomotive through a support. An air inlet and an air outlet are formed in the support. Pressure air which enters the support through the air inlet can flow to a control air inlet and a main air inlet of the valve body at the same time. The air outlet is communicated with two sand sprayers respectively through an air outlet channel. The sand spray control valve for the locomotive is characterized in that the valve body comprises an electromagnet component mounted in a coil, a packing cup, a piston, a lower valve, an upper valve and a compression spring, and further comprises a main air inlet chamber, an air outlet chamber and a phi 0.4 control air inlet. A pair of symmetric phi 1.8 air outlet holes is further formed in the valve body. The sand spray control valve for the locomotive has the advantages that the structure is simple, and the situation that a sand spray system on the locomotive does not have the self-cleaning function all the time is changed; the sand spray system can run normally for a long term, and therefore a reliable guarantee is provided for the traction and braking of the locomotive.
Description
Technical field
The present invention relates to
A kind of locomotive stucco control valve
Background technique
The stucco control valve that locomotive uses is solenoid valve, and as the control unit of sanding valve, thereby solenoid valve is just controlled simply the break-make realization stucco of air pipe line and stopped stucco.Can cause the stucco minimizing of stucco buret even sand pipe to stop up because of the deposition of sand grains after longer a period of time of sand sprayer work.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, for locomotive provides a kind of stucco control valve that possesses energising, stucco, three kinds of functions of cleaning.
Technological scheme of the present invention is---
A kind of locomotive stucco control valve, it relies on support 1 valve body 3 to be connected on the mounting flange of locomotive, offer intake grill 11 and exhaust outlet 10 in the described support 1, the pressure air that is entered by intake grill 11 can lead to control wind intake grill 12 and the main air intake intake grill 9 of valve body 3 simultaneously, this two pressure air passages intercommunication and generally all be in closed condition, exhaust outlet 10 then communicates with two sand sprayers respectively through air-out passage, it is characterized in that: the valve body 3 of this control valve comprises electromagnet assembly 2, leather cup 4, piston 5, lower valve 6, upper valve 7 and Compress Spring 8 also have main air inlet chamber 13, go out air compartment 14 and φ 0.4 control wind entrance 15; Described electromagnet assembly 2 dresses in coil, coil gets when electric, electromagnet assembly 2 moves down, and opens φ 0.4 control wind entrance 15; The inwall of valve body 3 is close in described leather cup 4 its outer rings, and after φ 0.4 control wind entrance 15 was opened, control wind can promote leather cup 4 drive pistons 5 and do axial motion; Described Compress Spring 8 between valve body 3 and upper valve 7, generally speaking, upper valve 7 can be close to valve port and closes main air inlet chamber 13 and go out 14 of air compartments under the effect of Compress Spring 8 passage; Also offer φ 1.8 exhaust vents 16 of a pair of symmetry in the described valve body 3.
The present invention is simple in structure, has changed the situation that stucco system on the locomotive never has self cleaning function.The long-term normal operation of stucco system provides reliable guarantee to traction and the braking of locomotive.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the present invention is in the closed condition schematic diagram;
Fig. 3 is that the present invention is in the stucco view;
Fig. 4 is that the present invention is in self cleaning momentary status schematic diagram;
Among the figure:The 1-support, 2-electromagnet assembly, 3-valve body, 4-leather cup, 5-piston, 6-lower valve, the upper valve of 7-, 8-Compress Spring, 9-master's air intake intake grill, 10-exhaust outlet, 11-intake grill, 12-control wind intake grill, 13-master's air inlet chamber, 14-goes out air compartment, 15-φ 0.4 control wind entrance, 16-φ 1.8 exhaust vents.
Embodiment:
Referring to Fig. 1, the present invention comprises support 1 and valve body 3, valve body 3 relies on support 1 to be connected on the mounting flange of locomotive, described support 1 itself offers with the air intake passage of intake grill 11 with the air-out passage of exhaust outlet 10, air intake passage divides main air intake passage and control wind passage, and this two passes is interconnected; And the air-out passage bifurcation is controlled two sand sprayer work simultaneously.Described valve body 3 contains dress electromagnet assembly 2, leather cup 4, piston 5, lower valve 6, upper valve 7 and Compress Spring 8 in coil.
Referring to accompanying drawing 2, at this moment coil of the present invention is in power failure state, and φ 0.4 control wind entrance 15 is closed, and upper valve 7 is close on the valve port, and main air inlet chamber 13 and the passage that goes out 14 of air compartments are closed, and the stucco control valve is in closed condition.
Referring to accompanying drawing 3, the coil of electromagnetic assembly of the present invention 2 peripheries is in to get electricity condition, φ 0.4 control wind entrance 15 is opened under electromagnetic force, pressure air slowly pushing piston 5 moves upper valve 7 is opened, so the pressure air of main air inlet chamber 13 enters out air compartment 14 by a pair of φ 1.8 exhaust vents, enter sand sprayer toward air-out passage again, realize the stucco function.
Referring to accompanying drawing 4, after stucco reaches the scheduled time, the coil losing electricity of stucco control valve, φ 0.4 control wind entrance 15 is closed, at this moment, piston 5 moves down under the effect of spring 8, in piston 5 folding processes, there is about 0.5 second time the situation that valve port is not closed and lower valve port is opened to occur, at this moment, the pressure wind of main air inlet chamber 13 enters out air compartment 14 simultaneously by a pair of Φ 1.8 exhaust vents 16 and lower valve port, the pressure wind of the unexpected enlargement discharge of this strand carries out the brute force purging to the stucco pipeline of sand sprayer, and guaranteeing does not have sand grains residual in the stucco pipeline.
Obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills are not making under the creative work prerequisite, and the every other embodiment who obtains belongs to the scope of protection of the invention.
