Abstract
The utility model discloses a kind of improved pilot valve filtrating equipment, in order to the oil in three oil ducts of valve body of flowing through, filter, this filtrating equipment is provided with three altogether, each filtrating equipment comprises that plug formula crosses filter core, screw thread fixing rod and plug screw, plug formula crosses the import of filter core and the oil inlet end of one of them oil duct is communicated with, plug formula is crossed filter core near being also provided with seal ring between a side of its import and valve body side opening end face, the circular radial cylinder that plug formula is crossed filter core has equally distributed some filtering hole, and filtering hole is communicated with the oil outlet end of this oil duct.The utility model has the advantages that: filtrating equipment of the present utility model respectively with three oil ducts corresponding setting one by one of valve body, when pilot valve supplies, effectively filtering is entrained in the pollutant in oil, greatly extended the working life of pilot valve, improved the reliability of pilot valve work, and simple in structure, assembly cost is low, is applicable to promoting the use of.
Description
Technical field
The utility model relates to pilot valve, is specifically related to a kind of improved pilot valve filtrating equipment being applied on large flow proportion valve.
Background technique
General large flow proportion valve, its pilot valve is not installed filter for installation, this just makes large flow proportion valve when pilot valve supplies, easily be subject to the impact of environmental pollution, the fragile pilot valve of pollutant causes malfunctioning, the functional reliability of this large flow proportion valve is reduced, cause equipment service life rate of fault high.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of simple and reasonable, reliable improved pilot valve filtrating equipment.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of improved pilot valve filtrating equipment, in order to the oil in three oil ducts of valve body of flowing through, filter, this filtrating equipment is provided with three altogether, each filtrating equipment comprises that plug formula crosses filter core, screw thread fixing rod and plug screw, the screw section of plug screw is connected with valve body side opening end-face helical, between the stepped part of plug screw and valve body side opening end face, be provided with seal ring, between the stepped part of screw thread fixing rod and plug screw endoporus, be provided with seal ring, the screw section of screw thread fixing rod is connected with plug screw inner hole thread, and cross an end in contact of filter core with plug formula, plug formula crosses the import of filter core and the oil inlet end of one of them oil duct is communicated with, plug formula is crossed filter core near being also provided with seal ring between a side of its import and valve body side opening end face, the circular radial cylinder that plug formula is crossed filter core has equally distributed some filtering hole, filtering hole is communicated with the oil outlet end of this oil duct.
Compared with prior art, the utility model has the advantages that: filtrating equipment of the present utility model is separately positioned on three oil ducts of valve body, when pilot valve supplies, effectively filtering is entrained in the pollutant in oil, greatly extended the working life of pilot valve, improved the reliability of pilot valve work, and simple in structure, assembly cost is low, be applicable to promoting the use of.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
Wherein, 1, valve body, 11, side opening, 2, seal ring, 3, oil duct, 4, plug formula crosses filter core, 41, filtering hole, 5, plug screw, 6, screw thread fixing rod.
Embodiment:
As shown in Figure 1 to Figure 2, a kind of improved pilot valve filtrating equipment, in order to the oil in 1 three oil ducts 3 of valve body of flowing through, filter, this filtrating equipment is provided with three altogether, each filtrating equipment comprises that plug formula crosses filter core 4, screw thread fixing rod 6 and plug screw 5, the screw section of plug screw 5 is connected with valve body 1 side opening 11 end-face helicals, between the stepped part of plug screw 5 and valve body 1 side opening 11 end faces, be provided with seal ring 2, between the stepped part of screw thread fixing rod 6 and plug screw 5 endoporus, be provided with seal ring 2, the screw section of screw thread fixing rod 6 is connected with plug screw 5 inner hole threads, and cross an end in contact of filter core 4 with plug formula, plug formula is crossed to filter core 4 to be fixed in side opening 11, the import that plug formula is crossed filter core 4 is communicated with the oil inlet end of one of them oil duct 3, plug formula is crossed filter core 4 near being also provided with seal ring 2 between a side of its import and valve body 1 side opening 11 end faces, the circular radial cylinder that plug formula is crossed filter core 4 has equally distributed some filtering hole 41, filtering hole 41 is communicated with the oil outlet end of this oil duct 3.
Above-mentioned three oil ducts 3 correspond respectively to oil input channel and two the work oil ducts in valve body 1, and three filtrating equipment connections corresponding to one one arrange, the pollutant being mixed with in the oil that makes to flow through in each oil duct 3 can be by effectively filtering, greatly improve the working life of pilot valve, improved the reliability of pilot valve work.
