There is certain interval in the minor diameter part of block, forms the groove for accommodating sealing ring between dividing, described sealing ring is fixed in groove.
First flange is by the radially inside inside of sidewall and around the inwall projection of a week.
Further, the end of the path part of described matrix is provided with for second flange spacing to sealing ring, described
The inner side of the first flange is provided with for the third lip spacing to sealing ring, the outer ledge of described muscle leaf and sealing ring casting die
Lateral wall flushes.
Further, the outside of described third lip is in the most gradually indent of sealing ring casting die.
Further, the mid portion of the miner diameter end end face of described matrix is provided with round table-like projection.
Further, the medial wall of described pilot hole is provided with radially inner and cincture inwall first projection of a week,
The round second projection of muscle leaf side it is provided with at the inside edge of described first projection.
Further, the material of described spool main body is nylon, and the material of described sealing ring casting die is rustless steel.
Compared with the prior art, valve core of the electromagnetic valve described in the utility model solve light material electromagnetic valve essence lack
Fall into, while reducing electromagnetic valve weight, ensure that intensity so that light material electromagnetic valve can be widely used, especially at electricity
Magnet valve needs to hang skyborne fire-fighting domain and can be widely popularized.

Detailed description of the invention
As shown in Figures 1 to 7, a kind of valve core of the electromagnetic valve, including spool main body 1, sealing ring 2 and sealing ring casting die 3；Described
Spool main body 1 includes the matrix 11 of boss-shaped, the newel 12 being fixed on matrix 11 bigger diameter end end face and is fixed on newel
On 12 and the most radial muscle leaf 13, the centre of described spool main body 1 is provided with pilot hole 14；Described sealing ring casting die
3 sidewalls 31 including cylindrical annular and be arranged on the first flange 32 inside described sidewall 31, described sidewall 31 and matrix 11
Large diameter portion is interfixed by screw thread, and the minor diameter part of described first flange 32 and matrix 11 exists certain interval, shape between dividing
Becoming the groove 4 for accommodating sealing ring 2, described sealing ring 2 is fixed in groove 4, and described muscle leaf 13 is rectangular paddle structure, institute
The lateral wall of the outer ledge and sealing ring casting die 3 of stating muscle leaf 13 flushes.First flange 32 be by sidewall 31 radially inside to
In and around the inwall projection of a week.
The end of the path part of described matrix 11 is provided with for second flange 15 spacing to sealing ring 2, and described first
The inner side of flange 32 is provided with for the third lip 33 spacing to sealing ring 2.Second flange 15 and third lip 33 reduce institute
State the opening of groove 4, make sealing ring 2 now be positioned at groove 4, and make the one side of sealing ring 2 pass through the opening of groove 4 towards outward
Side, is used for sealing, and the thickness of the second flange 15 and third lip 33 is less, while realization is spacing to sealing ring, does not affects
Sealing effectiveness.
The outside of described third lip 33, in the most gradually indent of sealing ring casting die 3, makes the 3rd
Edge's thickness of flange 33, less than the thickness with the first flange 32 junction, forms chamfering structure.
The mid portion of the miner diameter end end face of described matrix 11 is provided with round table-like protruding 16, and pilot hole 14 runs through spool main body
1, so pilot hole page 14 is through round table-like protruding 16.
The medial wall of described pilot hole 14 is provided with radially inner and around inwall first projection 17 of a week, and described the
Second projection 18 rounded of muscle leaf 13 side, the described first protruding 17 Hes it are provided with at the inside edge of one projection 17
Second protruding 18 for coordinating with valve rod, it is achieved seals.
The material of described spool main body 1 is nylon, and the material of described sealing ring casting die 3 is rustless steel, the spool master of nylon
Body 1 reduces the weight that spool is overall, and stainless sealing ring casting die 3 ensure that the intensity that spool is overall, the setting of muscle leaf 13,
Reduce further the weight of spool.
As shown in Fig. 8 to Figure 10, the valve core of the electromagnetic valve described in the present embodiment is installed in valve gap 5 under enforcement state,
Under electromagnetic valve opening, spool is almost overall all in the inside of valve gap 5, and during closed electromagnetic valve, spool is at valve rod
Active force under to the external movement of valve gap 5, be pressed on primary valve realization seal；During electromagnetic valve is opened, valve rod moves
Make, stop pressing spool, then the medium within valve gap 5 flow to primary valve by pilot hole 14, and spool is in the pressure of the medium flowed into
Move to valve gap 5 inside under power effect, make electromagnetic valve open.
Embodiment described above is only to be described the preferred embodiment of the present invention, the not model to the present invention
