Abstract
The utility model discloses a grease sprayer, which comprises a nozzle, a pump body, a grease inlet interface, a gas inlet interface, a valve chamber, a piston and a spring return. The grease sprayer pump body is internally provided with a drain pressure pipe circuit which is connected with the valve chamber and a spraying pipe. The spraying pipe is communicated with the nozzle and the valve chamber. The connection part between the spraying pipe and the nozzle is provided with a stop-grease atomizing one-way valve. The connection site between the nozzle and the spraying pipe adopts the stop-grease atomizing one-way valve design. A one-way valve is arranged between the spraying pipe and the nozzle. It can stop the leakage of the grease and mingle the compressed gas and greases to overcome the grease leakage produced from nozzle when the grease is transmitting the leakage caused by the friction after long time of sliding motion between the original piston and the valve chamber and leaks on the spraying pipe circuit.
Description
Technical field
The utility model belongs to a kind of wheel-rail lubricating device, particularly a kind of grease sprayer of wheel-rail lubricating device.
Background technology
Install and use wheel-rail lubricating device shower nozzle on the locomotive at present and exist certain defective, in the use of engineering traffic unit, have following problem: the shower nozzle material is softer, and in the loading and unloading use, back damage shower nozzle and the distortion that causes sprayer body easily collide with.The general purpose O-type seal ring is adopted in slipper seal between the plunger of shower nozzle and the plunger sleeve, often because of the aging distortion of O type circle causes plunger slip clamping stagnation with wearing and tearing back and forth, has increased the friction drag when air pressure promotes plunger simultaneously.Nozzle uses copper material, and in the loading and unloading use, little because of the jet hole aperture, the collision because of jet hole often results in blockage, and the bumping curved and bump disconnected phenomenon and produce of nozzle.Injection line directly is communicated with by inclined tube road, direct piping and nozzle, and it is relatively poor that pressurized air and grease mix the back atomizing effect, lacks the device that both mix the back atomizing.The plunger sleeve of sprayer body adopts the copper alloy material, though between plunger and plunger sleeve, formed the copper steel friction pair, improved resistance to abrasion, but often cause copper plunger sleeve because of particulate matter and unclean particulate matter the pulling on plunger sleeve of grease that the valve pocket wearing and tearing bring simultaneously, greatly reduce the service life of shower nozzle.
Summary of the invention
The purpose of this utility model provides a kind of pressure gas and grease of making and obtain abundant mixed aerosol between injection line and nozzle, prevents that the nozzle place from producing the grease sprayer of oil dripping phenomenon.
For achieving the above object, solution of the present utility model is: a kind of grease sprayer, form by nozzle, the pump housing, fuel inlet fitting, inlet suction port, valve pocket, plunger and retracing spring, be provided with the row pressure pipeline in the described sprayer pump housing, described row pressure pipeline is communicated with valve pocket and injection line, described injection line is communicated with nozzle and valve pocket, and described injection line is provided with only oil atomization check valve with the nozzle place of connection.
Adopt above-mentioned grease sprayer, because adopting, nozzle and injection line junction end the oil atomization one-way valve designs, between injection line and nozzle, there is one to end the seepage grease and make pressure gas and grease obtain the check valve of abundant mixed aerosol at this, original plunger and valve pocket have been overcome after the use of sliding over a long time, can produce the gap because of wearing and tearing, after grease leaks into injection line by this gap, thereby in nozzle place generation oil dripping phenomenon.After this device is set, not only can solve such problem, but also after pressure gas and grease are mixed through short stay herein, form evenly vaporific mixing pressure gas from taper spool annular gap, and then go out by nozzle ejection.Atomizing effect improved greatly after pressurized air and grease mixed like this, and had prolonged the service life of shower nozzle.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, this grease sprayer is connected with the pump housing 2 by nozzle 1, the pump housing 2 whole CuCrMo alloy cast iron materials that adopt.The described pump housing 2 is provided with chargine line 5 and inlet suction port 7, and described chargine line 5 tops are communicated with fuel inlet fitting 6, and fuel inlet fitting 6 one ends are communicated with oil tank by pneumatic hose, and fuel inlet fitting 6 other ends are installed in chargine line 5 upper ends of the sprayer pump housing 2.Describedly be communicated with valve pocket 14 by chargine line 5 and inlet suction port 7, described valve pocket 14 is a straight-though uniform cross section cavity, be provided with plunger 8 and retracing spring 11 in the described valve pocket 14, the two ends of described valve pocket 14 are separately installed with pressure regulating screw 15 and termination plug screw 9, described plunger 8 adopts the GCr15 bearing steel, after heat treatment reaches high-wearing feature.On described plunger 8, be provided with the quantitative trapped fuel groove 17 of ring-type, have additional multiple tracks simultaneously and store the grabage shoot of unclean particulate matter, described valve pocket 14 bottoms are provided with a U type air inlet revolution pipeline 13, and described air inlet revolution pipeline 13 communicates with uniform cross section valve pocket 14 when opening valve port.Described air inlet revolution pipeline 13 bottoms are provided with a plug 12.Be provided with row pressure pipeline 3 in the described pump housing 2, described row pressure pipeline 3 is communicated with valve pocket 14 and injection line 4, and described injection line 4 is communicated with nozzle 1 and valve pocket 14, and described injection line 4 is provided with only oil atomization check valve 16 with nozzle 1 place of connection.When the body pressure of calming the anger of inlet suction port 7 was zero, trapped fuel groove 17 alignd with chargine line 5, and the plunger 8 of sprayer promptly is in oil-filled initial position.When pressure gas enters in the valve pocket 14 by inlet suction port 7, under the promotion of the body of calming the anger, pressure gas enters uniform cross section valve pocket 14 right sides through admission line, overcomes the resistance of retracing spring 11, make plunger 8 under the effect of pressure gas and retracing spring 11, reciprocating in valve pocket 14.Grease is injected in the valve pocket 14 by fuel inlet fitting 6 and chargine line 5, grease is injected into down under the effect that the body of calming the anger is arranged in the trapped fuel groove 17 that has on the plunger 8, simultaneously under the body effect of calming the anger, promote plunger 8, open air inlet revolution pipeline 13, oil-feed revolution pipeline 13 is communicated with valve pocket 14, after grease in pressure gas and the trapped fuel groove 17 mixes, under the effect that the body of calming the anger is arranged, take away grease in the trapped fuel groove 17 to injection line 4, after ending oil atomization valve 16 position greases and fully mixing with pressurized air and atomize, and overcome the pressure of the spring 19 of taper valve core, annular slot by taper valve core 18 ejects from nozzle 1, realizes the lubricating effect to the locomotive wheel wheel rim.The grease sprayer is provided with three mounting holes 10, can be by being bolted on the mounting bracket.
