Abstract
A kind of stem sealing configuration of high-speed electro-magnet, comprise stem, seal ring and shell, stem realizes the sealed attachment with shell by seal ring, described seal ring is T-shaped seal ring, described T-shaped seal ring comprises the large end of Circular Plate structure and the small end of circular tube structure, described T-shaped seal ring is provided with the axial central through hole can inserting stem, and the corresponding rigging position of shell is provided with the ladder bore matched with T-shaped seal ring.The utility model sealability is reliable, and the airtight up-to-standard rate of practical application, more than 99%, is easy to processing in addition, is convenient to the advantage of assembling.
Description
Technical field
The utility model relates to the modified node method of diesel engine electric fuel-injection engine high-speed electro-magnet, the sealing configuration between especially a kind of field coil stem of diesel oil electronic fuel injection engine high-speed electro-magnet and electromagnet casing.
Background technique
Diesel electric-controlled oil spout technology has reached its maturity at home and has been promoted.High-speed electro-magnet is the pass key control performer in diesel electric-controlled injection system, directly contact because high-speed electro-magnet working surface has with high-pressure diesel in diesel engine, therefore require must have between the stem of excitation coil of electromagnet and electromagnet casing sealing and insulating property reliably.Existing high-speed electro-magnet mostly adopts O RunddichtringO to make sealing configuration, as shown in Figure 1, comprise stem 11, O RunddichtringO 12, shell 13, iron core 14 etc., its design of Sealing Structure is unreasonable, effect is poor, and in engineering manufacture, the airtight detection up-to-standard rate of electromagnet only can reach about 60%, causes electromagnet product qualified rate low, sealing reliability is low, there is leakage of oil risk in using process.
Summary of the invention
The utility model is to provide a kind of stem sealing configuration of high-speed electro-magnet, and its sealability is reliable, is easy to processing, is convenient to assembling.
The utility model adopts following technological scheme, comprise stem, seal ring and shell, stem realizes the sealed attachment with shell by seal ring, it is characterized in that: described seal ring is T-shaped seal ring, described T-shaped seal ring comprises the large end of Circular Plate structure and the small end of circular tube structure, described T-shaped seal ring is provided with the axial central through hole can inserting stem, and the corresponding rigging position of shell is provided with the ladder bore matched with T-shaped seal ring.
Its principle is: after mounting, Circular Plate is located at bottom the macropore of ladder bore in the large end of T-shaped seal ring of the present utility model, and Circular Plate axially loaded compresses, and achieves the radial seal function of seal ring; After the small end assembling of T-shaped seal ring between stem and the aperture inwall of ladder seat, seal ring small end radial force compresses, and achieves the axial seal function of seal ring.This construction increases the compression area of the sealed working face in whole sealed attachment district, twice sealing to same target can be realized, sealing reliability doubles relatively, avoids the deficiency that O RunddichtringO only can realize one-way sealing in high-speed electro-magnet sealing configuration.
The utility model adds the compression area of the sealed working face in sealed attachment district, and sealability is reliable, and the airtight up-to-standard rate of practical application, more than 99%, is easy to processing in addition, is convenient to the advantage of assembling.

In Fig. 2-4: stem 1, seal ring 2, shell 3, iron core 4, large end 6, small end 7, axial central through hole 8, ladder bore 9; In Fig. 1: stem 11, O RunddichtringO 12, shell 13, iron core 14.
Embodiment
As shown in Figures 2 to 4, a kind of embodiment of the utility model comprises stem 1, seal ring 2, shell 3, iron core 4, stem 1 realizes sealing after being assembled by seal ring 2 and shell 3, described seal ring 2 is T-shaped seal rings, T-shaped seal ring comprises the large end 6 of Circular Plate structure and the small end 7 of circular tube structure, described T-shaped seal ring is provided with the axial central through hole 8 can inserting stem 1, and the corresponding position of shell 3 is provided with the ladder bore 9 matched with T-shaped seal ring.
Its principle is: after mounting, Circular Plate is located at bottom the macropore of ladder bore 9 in the large end 6 of T-shaped seal ring of the present utility model, and Circular Plate axially loaded compresses, and achieves the radial seal function of T-shaped seal ring; After small end 7 assembling of T-shaped seal ring between stem 1 and the aperture inwall of ladder bore 9, small end 7 radial force compresses, and achieves the axial seal function of T-shaped seal ring.This construction increases the compression area of the sealed working face in whole sealed attachment district, twice sealing to same target can be realized, sealing reliability doubles relatively, avoids the deficiency that O RunddichtringO only can realize one-way sealing in high-speed electro-magnet sealing configuration.
The material if select with insulating property makes sealing circle, then can realize the insulating effect to electric conductor simultaneously.
T-shaped seal ring of the present utility model, can select fluorine rubber material that is high temperature resistant, the medium of resistance to mineral oil, adopts plastic squeeze sulfuration process shaping, to adapt to it 120 DEG C, use in 3MPa diesel oil medium.A kind of concrete preparation process, its process step is as follows: (1) selects 703 fluorine rubber as sealing ring material; (2) special plastic squeeze mould is processed by T-shaped seal ring boundary dimension; (3) plastic squeeze, the demoulding, after vulcanizing treatment, seal ring is made.
The utility model is not limited to the concrete structure of above-described embodiment, and the equivalent transformation of other homogeneous structure all falls within protection domain of the present utility model.
