Abstract
The utility model discloses an electromagnetic pump iron core assembly which has the advantages of simple structure and good sealing property. The utility model comprises an iron core, wherein the center of the iron core is provided with an oil through hole. One end of the iron core is provided with a mounting hole connected with the oil through hole. A plane flexibility valve sheet is arranged in the mounting hole. The inner wall of the mounting hole is provided with a plurality of valve sheet positioning strips. An oil through groove is arranged between the outer margin of the valve sheet and the inner wall of the mounting hole. The end part of the mounting hole is provided with a clamp spring.
Description
Technical field
The utility model relates to a kind of electromagnetic pump iron core assembly.
Background technique
Electromagnetic pump iron core assembly of the prior art, as shown in Figure 3, Figure 4, comprise iron core, plastics mushroom-shaped valve plug, Returnning spring, position shelf, jump ring, described core center is provided with oil through, one end of iron core is provided with the valve mounting hole that links to each other with oil through, the locating column of plastics mushroom-shaped valve plug is enclosed within the positioning hole of position shelf, is provided with Returnning spring between plastics mushroom-shaped valve plug and the position shelf, and position shelf is fixed by jump ring.The one-way sealing of this structure electromagnetic pump iron core assembly only depends on the inwall compression fit of plastics mushroom-shaped valve plug and oil through to realize, processing request height to the plastics mushroom-shaped valve plug, because plastics mushroom-shaped valve plug easy deformation, and surface roughness is difficult for reaching seal request, and therefore the sealability of this structure electromagnetic pump iron core assembly is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electromagnetic pump iron core assembly of simple in structure, good seal performance.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of electromagnetic pump iron core assembly, comprise iron core, described core center is provided with oil through, one end of iron core is provided with the mounting hole that links to each other with oil through, is provided with the planar flexible valve block in the described mounting hole, and the mounting hole inwall is provided with several valve block positioning strips, be provided with logical oily groove between the outer rim of valve block and the mounting hole inwall, the end of mounting hole is provided with jump ring.
In the technique scheme, the compression fit of described planar flexible valve block and oil through end face realizes sealing, and sealing surface is bigger, so sealability improves greatly; Compare with the electromagnetic pump iron core assembly of prior art, saved Returnning spring, position shelf, therefore simple in structure, assembling can reduce cost easily.

Embodiment
As Fig. 1, shown in Figure 2, a kind of embodiment of the utility model electromagnetic pump iron core assembly, comprise iron core 1, described iron core 1 center is provided with oil through 2, one end of iron core 1 is provided with the mounting hole 4 that links to each other with oil through 2, be provided with flat rubber valve block 3 in the described mounting hole 4, described mounting hole 4 inwalls are arranged with four valve block positioning strips 7, valve block 3 can be in the fixed position axial slippage of mounting hole 4, be provided with the logical oily groove 6 of four circular arcs between the outer rim of valve block 3 and mounting hole 4 inwalls, valve block positioning strip 7 is located at the joint of the logical oily groove 6 of adjacent two circular arcs, and the end of mounting hole 4 is provided with jump ring 5.Its working principle is: as Fig. 5, shown in Figure 6, when iron core 1 moves upward, rubber valve plate 3 is adjacent on the end face of oil through 2, realize the excellent sealing between oil pocket 8 and the flowline, can guarantee that enough oil masses are inhaled into oil pocket 8, compare with the electromagnetic pump iron core assembly of prior art, rubber valve plate 3 is bigger with the sealing surface of oil through 2 end faces, so sealability improves greatly; When iron core 1 moves downward, oil in the oil pocket 8 is compressed, the following side pressure of rubber valve plate 3 is greater than last side pressure, rubber valve plate 3 breaks away from the end face of oil through 2, in axially upwards slippage, when arriving the position of jump ring 5, jump ring 5 blocks valve block 3, the aperture of control valve block 3, the effect of four logical oily grooves 6 of circular arc are to increase logical pasta to amass, and guarantee to have enough oil masses to discharge.
