The specific embodiment
Accompanying drawing has provided an embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.
From accompanying drawing 1 as can be seen, the utility model is that a kind of air valve plate of controlling block of bow collector of electric locomotive comprises two gas circuits, by air filtration valve 1, rise bow one-way throttle valve 2, accurate voltage regulating valve 3, safety valve 4, fall bow one-way throttle valve 5 and form a gas circuit by two-way joint therebetween, form another gas circuit by the gas circuit dispense font at air-pressure gauge 6, detection port 7, double jump transformation power switch 8 places by flexible insulated hose.Enter described air filtration valve 1 through the nipple bent piece of described air filtration valve left end earlier by locomotive compressed and supplied air, after pressurized air is injected described air filtration valve 1, filter disc rotates under gas pressure, because the influence of centnifugal force, airborne moisture, impurity are thrown to the valve wall and flow down along the valve wall, thereby the liquid capacity that can find out accumulation by transparent liquid level display is in time drained, and enters two-way joint after the pressure gas of process rotating disk filters once more through 5 μ m filter cores.Pressurized air through double filtration is bent one-way throttle valve 2 through entering described liter behind the two-way joint, when gas circuit flows to when falling arciform attitude, be that pressure gas is when flowing from right to left, realization free flow that described liter bends in the middle of the pressure regulating valve and the avris path all can flow, can not influence and fall the bow airshed, not fall the bow time thereby do not influence.When gas circuit flowed to the arciform attitude of liter, when promptly pressurized air flowed from left to right, avris stopped up, and by the circulation of the gap on the filter core limit, realize throttling by the spinning in and out may command flow of knob, thereby realization rose the adjustment of bow time.Pressurized air through described liter bow one-way throttle valve 2 enters second two-way joint, enter described accurate voltage regulating valve 3 through the pressurized air of described liter bow one-way throttle valve 2 after through second two-way joint, set an occurrence by the knob compression spring in advance, when air pressure during greater than setting value, red diaphragm is by jack-up, middle aperture loses heart, by normal drain port exhaust to atmosphere; When air pressure during smaller or equal to setting value, aperture is by the piston dieback in the middle of the red diaphragm, and pressurized air does not leak.Described accurate voltage regulating valve band air-pressure gauge, what air-pressure gauge showed is through the gas circuit air pressure behind the accurate voltage regulating, pressurized air through described accurate voltage regulating valve 3 enters the 3rd two-way joint, pressurized air after described accurate voltage regulating valve 3 pressure regulation enters described safety valve 4 place gas circuit dispense font after through the 3rd two-way joint, the knob of described safety valve 4 puts on pressure on the seal ring by spring, the big I of pressure is set by knob compression spring length, when air pressure just often, seal ring and disappointing port closed contact; When air pressure during greater than spring pressure, seal ring is by jack-up, and gas circuit is led to atmosphere, thereby realizes overvoltage protection.Pressurized air through described safety valve 4 place gas circuit dispense font enters the 4th two-way joint, enter the described bow one-way throttle valve 5 that falls through the pressurized air of described safety valve 4 place gas circuit dispense font after through the 4th two-way joint, pressurized air enters gas channel of pantograph by flexible insulated hose after through the described nipple bent piece that falls bow one-way throttle valve the right.
The flexible insulated hose that connects out from gas channel of pantograph is connected to the gas circuit dispense font of air valve plate right-hand member, and described air-pressure gauge 7, detection port 6, pressure switch 8 all are installed on the gas circuit dispense font.The atmospheric gas pressure that described air-pressure gauge 7 shows in the gas circuit dispense font can detect and regulate after described detection port 6 is backed down gas atmosphere in the gas circuit dispense font.Described pressure switch 8 air cavitys connect the gas circuit dispense font, and electric interfaces connects the locomotive control circuit by the electric wire of band protecting sleeve.The piston below of pressure switch is subjected to action of the spring; the top is subjected to air pressure; when air pressure changes near setting value; the contact changes; thereby give the electromagnetic valve electric signal to realize lifting bow process monitoring and to fall the bow protection automatically by circuit; the trip point of pressure switch has nothing in common with each other in lifting bow process, can change as requested.
