Description
Technical field
The utility model is related to gas spray valve technical field, more particularly to a kind of Electromagnetic Control valve element is opened and closed
Gas spray valve.
Background technology
Chinese invention patent CN105042177B discloses a kind of gas spray valve with buffer gear, Chinese invention patent
CN104197027B also discloses that a kind of monoblock type double valve gas spray valve and its assembly method, its disclosed gas spray valve
In, electromagnetic coil structure is located at the side of moving armature, has a disadvantage that：
1) in order to improve electromagnetic force, leakage field is reduced, coil can not be far from moving armature, normally only with a very thin epoxy
Glue separates the space of coil and moving armature, and coil is in close to UNICOM with inner chamber, if what is be full of in magnetic valve is combustible gas
Body, then have certain potential safety hazard.
2) after armature adhesive, electromagnetic force is larger, but with the motion of valve element, quickly, therefore magnetic gap increase, electromagnetic force decays
The stroke for designing valve element can not be too big, influences the raising of valve flow.
Utility model content
For more than prior art not enough, the gas spray valve put in a kind of magnetic valve of the utility model offer, to solve
Certainly the fuel gas in valve easily contacts the technical problem that there is potential safety hazard with magnet coil, the gas spray valve spool stroke
Greatly, valve flow can be improved.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of gas spray valve put in magnetic valve,
Including：Valve seat and valve pocket are provided with the front valve shell and rear valve body being fixed together, the front valve shell；Valve element, the valve
Core includes valve rod, valve block and the valve tail that order is set, and the valve block is adapted with the valve seat, and the valve stem slides are installed on institute
State in the mounting hole of valve pocket；Moving armature, static gag bit and magnet coil, the moving armature are fixed on the valve tail, the static gag bit
The rear valve body is fixed on, the rear valve body is sealedly connected with end cap, the magnet coil and is placed in the rear valve body and described
In end cap, be provided with magnetism-isolating loop in the endoporus of the magnet coil, two end faces of the magnetism-isolating loop be posted by respectively it is described after
The side wall of valve body and the inner side end formation flat seal of the end cap, centre bore of the moving armature through the end cap stretch into institute
The endoporus of magnetism-isolating loop is stated, the static gag bit stretches into the endoporus of the magnetism-isolating loop from the other end.
Wherein, the magnetism-isolating loop every magnetic metal material by constituting.
Wherein, return spring is provided with sheathed spring sleeve in the endoporus of the static gag bit, the spring spool, it is described
The end of valve tail leans the return spring.
After adopting the above technical scheme, having the technical effect that acquired by the utility model：
1) due to being placed in magnet coil in rear valve body and end cap, the surrounding of magnet coil is by rear valve body, end cap and every magnetic
Ring is surrounded, and magnet coil is completely separated by magnetism-isolating loop, rear valve body and end cap with gassiness body cavity, safe.
2) compared with known technology, moving armature increases with spool stroke, and electromagnetic force decay is relatively fewer, therefore, is ensureing
Under conditions of electromagnetic force is constant, bigger spool stroke can be allowed, valve flow is improved.
Brief description of the drawings
Fig. 1 is the structure sectional view of the utility model embodiment；
Fig. 2 is electromagnet and known magnet coil side electromagnetism iron electromagnet curve control figure in Fig. 1；
In figure, 1- front valve shells, 2- rear valve bodies, 3- end caps, 4- valve elements, 5- valve seats, 6- valve pockets, 7- magnet coils, the dynamic ranks of 8-
Iron, 9- magnetism-isolating loops, 10- static gag bits, 11- spring spools, 12- return springs, t- magnetic gaps.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, the gas spray valve put in a kind of magnetic valve, front valve shell 1 and rear valve body 2 are fixed together,
Valve seat 5 and valve pocket 6 are provided with the front valve shell 1, valve element 4 includes valve rod, valve block and valve tail, valve block and the valve seat that order is set
5 are adapted, and valve stem slides are installed in the mounting hole of valve pocket 6.The moving armature 8 of electromagnet is fixed on valve tail, and static gag bit 10 is fixed
Return spring 12 is provided with the sheathed spring sleeve 11 in rear valve body 2, the endoporus of static gag bit 10, spring spool 11, valve tail
End leans return spring 12.
Rear valve body 2 is connected with end cap 3, between the two provided with sealing ring, and rear valve body 2 and end cap 3 are placed in magnet coil 7
It is interior, " in put " be with " side " comparatively.Magnetism-isolating loop 9 is provided with the endoporus of magnet coil 7, magnetism-isolating loop 9 is by every magnetic gold
Belong to material to constitute, two end faces of magnetism-isolating loop 9 are posted by the side wall of rear valve body 2 and the inner side end formation plane of end cap 3 respectively
Sealing, so, the surrounding of magnet coil is just surrounded by rear valve body 2, end cap 3 and magnetism-isolating loop 9, makes magnet coil 7 with being full of
The body cavity of gas (being also likely to be fuel gas) is isolated entirely from, and eliminates potential safety hazard.Installed for the ease of part, after
Valve body 2 is configured to Split type structure.
Centre bore of the moving armature 8 through end cap 3 stretches into the endoporus of magnetism-isolating loop 9, and static gag bit 10 stretches into magnetism-isolating loop 9 from the other end
Endoporus, two end faces are relative, and magnetic gap t is left in centre, and magnetic gap t is the stroke of valve element 4.Fig. 2 shows what is mentioned in background technology
The electromagnetism curve control figure of electromagnet in the magnetic valve and the above embodiments of the present application of known features, from figure 2 it can be seen that with
Known technology is compared, and moving armature increases with spool stroke in the present embodiment, and electromagnetic force decay is relatively fewer, therefore, is ensureing electricity
Under conditions of magnetic force is constant, bigger spool stroke can be allowed, valve flow is improved.
