Press in the oil lifter device of said structure composition, when loading,, supply with pressure oil lift 3 by filter 8 and pipeline 9 from the power fluid of oil pressure pump 2 outputs with cage 6 rising operations, make the piston elongation of pressure oil lift 3, carry with irritating cage 6 risings thereby this is taken advantage of.Carry with irritating cage 6 when descending operation and take advantage of,,, return in the oil pressure power plant 1, make the piston retraction of pressure oil lift 3 thus, descend and cause to take advantage of to carry with irritating cage 6 then by the filter 8 in the hydraulic silencer in the power fluid of pressure oil lift 3 internal flows at this.At this moment, impurities and dust etc. in the power fluid turn back in the process of oil pressure power plant at power fluid, are filter 8 and block, and are removed.
Above-mentioned setting is the filter 8 that adopts in the hydraulic silencer 5, makes from the impurity of pressure oil lift 3 and dust etc., can not return to fall back in the oil pressure power plant 1.
For above-mentioned prior oil pressure noise silencer, because it is bigger than the diameter of pipeline opening that filter is made into, it installation or unload process, must split the part of hydraulic silencer, like this, just existed to make it all adopt welded structure, so that make simple in structure and the problem of leakage of oil does not take place.
The present invention's purpose is to address the above problem, and provides a kind of only adopting under the welded situation, also is easy to change the hydraulic silencer of filter.
Hydraulic silencer of the present invention, get welded structure simultaneously making its integral body, allow and be contained in its in-to-in filter and be made for the size little than the bore of pipeline opening in the hydraulic silencer, and one flange is set in the one end, and this filter is inserted from the pipeline opening of hydraulic silencer, and in pipeline opening and be connected between the conduit of this pipeline opening,, this filter is fixed by the flange of clamping.Remove this, between the inwall of the fore-end of filter and hydraulic silencer, be provided with spring,, make this filter can revolt flowing of power fluid by the effect of this spring, pressing is to the pipeline that links to each other with this pipeline opening, thereby prevented that this filter from extensional taking place simultaneously collecting dust etc.
Hydraulic silencer of the present invention, be to become under the condition of external diameter less than the bore of pipeline opening will being loaded on its in-to-in filter design, insert from this pipeline opening, simultaneously by being located at the flange of its end, make it to be clamped between this pipeline opening and the pipeline, owing to such reason, just need be as situation in the past, its part is become by bolted structure, so that when changing filter, this being unloaded just by bolted part can be carried out the loading and unloading of filter, thereby just improved operating efficiency greatly.And because integral body has all been taked welded structure, simplified structure and made, also made low price.Also owing between the front end of the inwall of hydraulic silencer and filter, be provided with stage clip, can prevent the filter distortion that when the collection dust, stretches.
The contrast accompanying drawing illustrates one embodiment of the invention below.In Fig. 1,10 is the cylinder-like part that constitutes filter 8 and flange is at one end arranged, and 11 for being welded to the mesh members on the cylinder- like part 10, and 12 for being positioned on the stage clip on this mesh members.20 for being connected to pipeline on the pipeline opening 7, and 21 for being connected to the pipeline on the pipeline opening 9, and 22 and 23 are respectively pipeline 20 and 21 is connected to joint on pipeline opening 7 and 9.
In the hydraulic silencer of said structure, filter 8 is inserted in the hydraulic silencer 5 from pipeline opening 7, by the flange that is located at cylinder-like part 10 1 ends, is clamped between pipeline opening 7 and the pipeline 20, and is maintained by joint 22.By stage clip 12, this filter 8 is pressed constantly be attached on the pipeline 20 simultaneously.Like this, the compressed oil from pressure oil lift 3 returns promptly from pipeline opening 9, by hydraulic silencer 5 in-to-in mesh members 11, and flows out from pipeline opening 7.At this moment, from the impurity and the dust of pipeline opening 9, because the effect of mesh members 11 is prevented from flowing to pipeline opening 7 one sides.Thereby, because pipeline opening has been arranged, just carry out the installation and removal of filter easily, and whole hydraulic silencer 5 just can be pressed the welded structure manufacturing.
Should be understood that, though top only be just filter 8 to be installed to the explanation that pipeline opening 7 one sides are done, even this filter 8 is assemblied in a side of pipeline opening 9, also can obtain identical effect.
