Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, it is further elaborated below in conjunction with the drawings and Examples valve rotor structure to the present invention and electromagnetic valve.Should be appreciated that specific embodiment described herein is only for explaining the present invention, is not intended to limit the present invention.
Seeing figures.1.and.2, the valve rotor structure of one embodiment of the invention includes needle sleeve 1, annular metal sheet 2 and axial limiting part 3, and the upper end of needle sleeve 1 is provided with bulge loop 11 and annular projection portion 12, and annular projection portion 12 is placed in the upside of bulge loop 11.Annular metal sheet 2 is set in annular projection portion 12, the peripheral shape in annular projection portion 12 is suitable with endoporus 21 shape of annular metal sheet, for preventing annular projection portion 12 and annular metal sheet 2 from relatively rotating, that is annular projection portion 12 is when being placed in the endoporus 21 of annular metal sheet, annular projection portion 12 and annular metal sheet 2 cannot relatively rotate.One end (for lower end in figure) of axial limiting part 3 is embedded in the endoporus 121 in annular projection portion, thus by annular metal sheet 2 axial restraint.The peripheral shape in annular projection portion 12 is suitable with endoporus 21 shape of annular metal sheet, it is ensured that needle and the good axiality of Magnet, it is achieved that accurate assembly.The assembling of valve rotor structure, without spot-welding technology, decreases assembly process, it is to avoid the generation of Magnet high temperature demagnetization.
The endoporus 21 of annular metal sheet is polygonal hole or track type hole, is certainly alternatively hole in irregular shape, and annular metal sheet 2 is preferably iron plate.The lower end of needle sleeve 1 is provided with external screw thread 14.
As a kind of embodiment, axial limiting part 3 is two sections of cylinders being connected, respectively first paragraph cylinder 31 and second segment cylinder 32, and first paragraph cylinder 31 and second segment cylinder 32 are coaxial, and the diameter of first paragraph cylinder 31 is less than the diameter of second segment cylinder 32.The fit system of the endoporus 121 in axial limiting part 3 and annular projection portion is interference fit.First paragraph cylinder 31 is for coordinating with the endoporus 121 in annular projection portion, and second segment cylinder 32 is used for stopping that ring-type sheet metal 2 moves axially along first paragraph cylinder 31.
As a kind of embodiment, valve rotor structure also includes grab 33, and grab 33 is arranged on second segment cylinder 32, and annular metal sheet 2 arranges pilot hole 22, grab 33 runs through pilot hole 22, bulge loop 11 is provided with and keeps away bit space 13 for what grab 33 kept away position.
Preferably, pilot hole 22 is scallop hole, and the cross section of grab 33 is fan-shaped, and grab 33 is suitable with described scallop hole, keeps away bit space 13 and keeps away bit space for sector.The setting of pilot hole 22, furthermore achieved that accurate assembly, improves efficiency of assembling.
Further, grab 33 is connected on bulge loop 11, more improves the fastness that annular metal sheet 2 is fixing.
The invention still further relates to an electromagnetic valve, as shown in Figure 2, wherein, the annular sheet metal 2 of valve rotor structure is nested in the inside of the Magnet 4 of electromagnetic valve, and Magnet 4 is tubular, and the inner and outer wall of Magnet 4 is cylinder, Magnet 4 and annular sheet metal 2 can integrated injection moldings, the annular projection portion 12 of needle sleeve 1 is loaded in the endoporus 21 of annular metal sheet, assemble from lower to upper, thus needle sleeve 1 is assemblied in annular metal sheet 2；Again needle 5 is loaded in needle sleeve 1 from the upper end of the endoporus 121 in annular projection portion, finally by axial limiting part 3 by holding device press-in needle sleeve 2, axial limiting part 3 and needle sleeve 2 interference fit, not only ensure that needle 5 is compacted, axial limiting part 3 is also not easy to loosen simultaneously, pilot hole 22 aligns with fan-shaped bit space 13 of keeping away, and has following 2 effects: occur when (1) avoids assembling axial locating part 3 that fan-shaped bit space 13 of keeping away is blocked by the upper surface of the bulge loop 11 of needle sleeve；(2) ensure that needle 5 and the good axiality of Magnet 4.Whole assembling process is provided without spot-welding technology, it is achieved that accurate assembly, and needle sleeve 1 in turn ensure that needle 5 and Magnet 4 have good axiality requirement simultaneously.
The valve rotor structure of above example and electromagnetic valve, it is not necessary to spot-welding technology, decrease assembly process, it is to avoid the generation of Magnet high temperature demagnetization.Pilot hole and the valve needle cover barrel structure of guide effect are set, it is ensured that needle and the good axiality of Magnet, it is achieved that accurate assembly.Rotor position limiting structure directly holds out against the needle in needle sleeve simultaneously, further increases the stability of needle.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
