Accompanying drawing illustrates: 10, valve body; 20, spool; 21, iron-clad; 22, magnetic conduction core; 23, magnet; 24, coil; 25, iron core; 31, sealing block; 32, metal cirque; 40, valve gap; 41, salient point; 42, valve.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
A kind of New Type Proportional valve as Figure 1-3, comprises valve body 10, valve gap 40, spool 20 and magnet 23, valve gap 40 offers valve 42, and gas is entered by this valve 42; In addition, this valve body 10 has an inner chamber, spool 20 activity be arranged in this inner chamber, magnet 23 is then fixed in this inner chamber, and when being energized, magnet 23 and spool 20 interact, thus make spool 20 reciprocating relative to magnet 23, reach the effect of closed valve 42 in reciprocatory movement by spool 20, thus control the flow of gas, play regulating and controlling effect.
Concrete, above-mentioned spool 20 comprises sealing block 31 and coil block, and coil block is fixedly connected with above-mentioned sealing block 31, and on sealing block 31, be fixed with a metal cirque 32; So, when coil block is energized, coil block can produce a magnetic field contrary with magnet 23 magnetic pole, and under the effect in this magnetic field, this coil block can produce mutual repulsive force with magnet 23, when input current is enough large, this repulsive force is greater than the attraction force of magnet 23 pairs of metal cirques 32, and now, this repulsive force promotes the sealing block 31 be fixed on coil block and moves towards near valve 42 direction, in the process of constantly movement, valve 42 is closed by sealing block 31 gradually; And when input current reduces gradually, the attraction force of magnet 23 pairs of metal cirques 32 can be greater than the repulsive force produced between coil block and magnet 23, like this, metal cirque 32 can drive sealing block 31 towards the movement away from valve 42 direction, thus opens valve 42.So, under different input currents, sealing block 31 can make axially reciprocating in valve body 10, to play the effect of opening valve 42 or closed valve 42, thus reaches the effect controlling throughput.Compared to used spring of the prior art, the utility model adopts metal cirque 32 to carry out the aperture of control valve with the interaction of magnet 23, reduces the unstability brought when using spring, makes product performance more stable.
Preferably, coil block comprises iron core 25 and is set around the coil 24 of iron core 25 outer surface, this coil 24 is directly set around the outer surface of iron core 25, compared to before by coil 24 and roll separate machined, fixed by the mode of a glue, this processing mode is easier, can cut down finished cost.Further, the upper end of above-mentioned iron core 25 protrudes from coil 24 and forms lug boss, above-mentioned sealing block 31 is fixed on the outer surface of lug boss, and this structure effectively can save the space in valve body 10, reduces valve body 10 volume.
Preferably, lug boss is provided with buckle, the upper-end surface of buckle and coil 24 forms position-limit mechanism, and when being energized, this position-limit mechanism can prevent coil 24 and iron core 25 from departing from, and causes the forfeiture of magnetic core, improves the stability of product.
Preferably, the inwall of valve gap 40 is provided with multiple salient point 41, the plurality of salient point 41 is around the central axis circle distribution of valve 42, like this when closed valve 42, sealing block 31 can contact prior to salient point 41, make sealing block 31 and valve gap 40 inwall have certain interval, only when magnetic force is enough large, valve 42 could be closed by sealing block 31 completely; And when opening valve 42, this salient point 41 and the effect also playing a gas bleeder valve that coordinates of sealing block 31, be convenient to the aperture adjustment of valve.
Preferably, pin is provided with in valve body 10, pin is by being electrically connected with coil block in the movable incoming end being plugged in coil 24, so, when spool 20 moves, the length bearing of trend along latch that spool 20 just can be fixed is movable, prevents spool 20 from rocking in reciprocatory movement, makes electromagnetic effect more stable.
Preferably, in above-mentioned inner chamber, arrange one for the iron-clad 21 of receipt of wire coil assembly and magnet 23, the setting of this iron-clad 21 strengthens spool 20 and the magnetic of magnet 23, avoids leakage field; Further, above-mentioned magnet 23 comprises magnetite and is socketed on the magnetic conduction core 22 of magnetite outer surface, and the bottom of magnetic conduction core 22 abuts with the diapire of iron-clad 21, and the magnetic Circuit Design adopting magnetite to add magnetic conduction core 22 effectively can improve the magnetic circuit efficiency of product, reduce product energy consumption, enhance product performance.In the present embodiment, because of magnetite stable performance, be conducive to the stability strengthening whole product, therefore magnet 23 preferably adopts magnetite; In other cases, above-mentioned magnet 23 also can adopt another electromagnet contrary with above-mentioned coil block magnetic or the magnetic magnet 23 of other tools.
To one skilled in the art, according to technological scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
