Description
Technical field
This is novel to be relevant grease to be imported the grease compressor (Grease gun) of other machines, device, the pressure-relief valve structure of especially relevant electronic or pneumatic grease compressor.
Background technique
Various patents with grease compressor of decompression mechanism are arranged, and for example U. S. Patent 5,779, and 105,4,219,131,4,063,618,4,062,425 etc.Above-mentioned each U. S. Patent does not disclose grease compressor when pressure release, grease can be drained the structure in the oil return fat tube.Grease compressor if grease is discharged the grease compressor outside, will be wasted grease, and can pollute user and environment when pressure release.
Quiet consult shown in Figure 1.No. the 242941st, Taiwan patent announcement discloses a kind of structure-improved at electronic injection grease gun, and its main feature is in the nearly outlet port of the compression pipe 31 of the loam cake 3 of oil tube 2, is provided with a releasing pressure automatically mouth 32.Be provided with a spheroid 33 in the pressure relief opening 32, spheroid 33 bottoms are withstood by a spring 34.The effect of a pressure relief opening 32 thus can be drained the butter of excess pressure in the oil returning tube 2, guarantees grease gun 1 unlikely damage.
Above-mentioned Taiwan patent discloses the pressure relief of grease gun, though butter can be drained in the oil returning tube, but the force value of its pressure release is fixed, the user can't look actual the force value that behaviour in service is adjusted pressure release, when the pressure of surpass setting when needs could be filled with butter, because when surpassing the force value of setting, butter promptly can be drained in the oil returning tube, can't fill with butter, and cause the inconvenience in the use.
The model utility content
For improving the pressure-relief valve structure of known grease compressor, can not adjust the shortcoming of the force value of pressure release, and propose originally novel.
The main purpose that this is novel is providing a kind of pressure-relief valve structure of grease compressor, and the user can optionally adjust the force value size of pressure release.
Another purpose that this is novel is providing a kind of pressure-relief valve structure of grease compressor, and the user can conveniently adjust the force value of pressure release, makes grease compressor have value widely.
The pressure-relief valve structure of a kind of grease compressor of the utility model is characterized in that, comprises that a body has compression pipe, first, pipeline, and second pipeline, the 3rd pipeline reach in order to the opening in conjunction with the grease tube; This compression pipe has the opening that a pressure relief opening and is communicated to this body exterior; The inside socket one of this compression pipe can move back and forth the piston of position; This pressure relief opening is near the opening of this compression pipe; The two ends of this first pipeline are communicated with this compression pipe respectively and this is in order to the opening in conjunction with the grease tube; One end of this second pipeline communicates with this pressure relief opening, and the other end is another opening that is communicated to this body exterior; Socket one spheroid, an elastic element and the screw rod that is spirally connected in this second pipeline; One end of this elastic element of front end ejection of this screw rod, this spheroid of the other end ejection of this elastic element is so that this spheroid has the strength of keeping this pressure relief opening of sealing; The 3rd pipe ends is communicated with this second pipeline respectively and this is in order to the opening in conjunction with the grease tube; Stretch into length in this second pipeline utilize to adjust this screw rod, adjust the decrement of this elastic element, to control the pressure that this spheroid seals this pressure relief opening.
Wherein the tail end of this screw rod stretches out the opening outside of this second pipeline.
Description of drawings
Other purposes, effect that this is novel see also drawings and Examples, be described in detail as follows, wherein:
Fig. 1 is the schematic representation of the pressure-relief valve structure of known grease compressor.
Fig. 2 is the pressure-relief valve structure embodiment's of this new oil rifle a schematic representation.
Fig. 3 is the pressure-relief valve structure schematic representation during pressure release not of this new oil rifle.
Schematic representation when Fig. 4 is the pressure-relief valve structure pressure release of this new oil rifle.
Fig. 5 is another embodiment's of pressure-relief valve structure of this new oil rifle a schematic representation.
Embodiment
See also shown in Fig. 2,3,5.The pressure-relief valve structure embodiment of this new oil rifle comprises that a body 10 has compression pipe 11, first pipeline 12, second pipeline 13, the 3rd pipeline 141 and in conjunction with the opening 15 of grease tube 20.Compression pipe 11 has the opening 112 that a pressure relief opening 111 and is communicated to body 10 outsides.Compression pipe 111 inner sockets one can move back and forth the piston 16 of position.Pressure relief opening 111 is near opening 112.The two ends of first pipeline 12 are communicated with compression pipe 11 and opening 15 respectively.One end of second pipeline 13 communicates with the pressure relief opening 111 of compression pipe 11, and the other end is another opening 134 that is communicated to body 10 outsides.Socket one spheroid 131, an elastic element 132 and the screw rod 133 that is spirally connected in second pipeline 13, the tail end of screw rod 133 stretches out opening 134 outsides of second pipeline 13, and perhaps the tail end of screw rod 15 as shown in Figure 5 is in opening 134.One end of the front end ejection elastic element 132 of screw rod 133, the other end ejection spheroid 131 of elastic element 132 has spheroid 131 and keeps the strength of sealing pressure relief opening 111.The 3rd pipeline 14 two ends are communicated with second pipeline 13 and opening 15 respectively.
The opening 15 of present embodiment body 10 is in conjunction with the opening 21 of grease tube 20.When piston 16 when move on the left side of circle shown in 2, the greases in the grease tube 20 can enter compression pipe 11 through first pipeline 12.When piston 16 is mobile toward the right shown in Figure 3, can promote the grease discharge aperture 112 in the compression pipe 11.
See also shown in Figure 4.When grease is filled with, in the time of can't be again with grease discharge aperture 112, when the pressure of grease seals the pressure of pressure relief openings 111 greater than spheroid 131 near the pressure relief opening 111, grease promptly can be via pressure relief opening 111 pushing spheroids 13, overcome elastic element 132 and bestow the elastic force of spheroid 131, make spheroid 131 no longer seal pressure relief opening 111, grease also is back in the grease pipe 20 via the 3rd pipeline 14, and can not damage grease compressor.
The user can utilize the whole screw rod 133 of screwdriver or hand adjustment to stretch into length in second pipeline 13, adjust the decrement of elastic element 132, with the different pressure of control spheroid 131 sealing pressure relief opening 111, to be fit to the pressure demand of various oiling fat, make grease compressor have value widely.And the tail end of screw rod 133 stretches out the outside of body 10, and the user utilizes the tail end of screw rod 133 can adjust the pressure of pressure release easily.
The above record only for utilizing the embodiment of this new technique content, anyly is familiar with modification, the variation that this operator uses the utility model to do, and all belongs to the claim of this novel opinion, and is not limited to the content that embodiment discloses.
