Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the electromagnetic oscillation pump 10 of the utility model embodiment, comprises valve body 11, Decompression valves, suction valve, the first spring 12, plunger 13, second spring 14, sleeve 15, first iron ring 16, cushion rubber 17, second iron ring 18, coil overmold 19, fixing frame 20 and fixed cover 21.One end of sleeve 15 is provided with water intake 151.One end of valve body 11 is provided with water outlet 111.Valve body 11 is provided with center hole.Plunger 13 comprises the plug 131 being inserted into this center hole.
Compressing member 22 is provided with between valve body 11 and sleeve 15.Compressing member 22 is set on the plug 131 of plunger 13.Seal ring is provided with between the end face of compressing member 22 and the end face of valve body 11.Plug 131 from the center hole of seal ring through and with seal ring interference fit.First spring 12 is pressed on compressing member 22 towards on the end face of plunger 13.Alternatively, between the end face of compressing member 22 and valve body 11, seal ring is not set.
The periphery of the end of the free end of plug 131 is provided with circumferential hoop connected in star.Sealing 23 is mounted with in annular groove.Annular groove can be formed spacing to Sealing 23, when Sealing 23 synchronously moves in company with plug 131 in the center hole of valve body 11, annular groove can provide thrust to Sealing 23, ensures that Sealing 23 can not cannot play the effect in compression seal space 99 along moving axially of plug 131.Plug 131 is inserted in the center hole of valve body 11, and Sealing 23 contacts with the hole wall of the center hole of valve body 11.
The center bore inner wall of valve body 11 is provided with annular flange flange 112, the first spool 24 seated connection of Decompression valves is in annular flange flange 112, and annular flange flange 112 plays the effect of valve seat.The top of the first spool 24 is arranged in hole that annular flange flange 112 formed and does not cross this hole and extend into seal space 99, thus the first spool 24 can not come in contact with the second spool 25 all the time, therefore avoid sticking together between the first spool 24 and the second spool 25 phenomenon.Second spool 25 seated connection of suction valve is at the top of plug 131, and plug 131 plays the effect of valve seat.Be spaced a distance between second spool 25 of suction valve and annular flange flange 112, thus the second spool 25 of the first spool 24 of Decompression valves and suction valve toward each other and interval arrange.
As shown in Figure 1 and Figure 2, Decompression valves, valve body 11, suction valve, plug 131 and Sealing 23 form a seal space 99.Sealing space 99 belongs to a part for valve body 11 center hole.Under the effect of the magnetic force produced at coil overmold 19 when plunger 13, Sealing 23 synchronously can move back and forth with plug 131 volume changing seal space 99 in the center hole of valve body 11.Preferably, Sealing 23 is O RunddichtringO.
In intermediate links such as long-term transport, storages, between the second spool 25 of the first spool 24 of Decompression valves and annular flange flange 112, suction valve and plug 131, likely there is pinning phenomenon.
After coil overmold 19 is energized, plunger 13 back and forth can shake motion in sleeve 15.When plug 131 moves towards Decompression valves, plug 131 and Sealing 23 compression seal space 99, the volume of seal space 99 sharply reduces, material (such as air or water) in seal space 99 is compressed, thus the pressure of seal space 99 sharply raises, and then the pressure that the first spool 24 of Decompression valves is subject to becomes large.The pressure be subject to towards the surface of seal space 99 when the first spool 24 of Decompression valves is greater than the atmospheric pressure acted on the first spool 24, and the pressure difference that the first spool 24 is subject to is when being greater than the Adhesion force between the first spool 24 and annular flange flange, first spool 24 can depart from tacky state with annular flange flange 112, thus Decompression valves is opened.After first spool 24 of Decompression valves is opened, the material of seal space 99 is discharged, and the pressure of seal space 99 diminishes.
After Decompression valves is opened, plug 131 and Sealing 23 start to move from the position of the first spool 24 near Decompression valves toward the first spool 24 direction away from Decompression valves.Plug 131 and Sealing 23 are away from the movement process of Decompression valves, and the first spool 24 reset seat of Decompression valves is connected in annular flange flange to form sealing.Seal space 99 starts sharply to increase, and the material (such as air or air and water) in seal space 99 expands, and the pressure of seal space 99 sharply reduces.The pressure that second spool 25 of suction valve is subject to towards the first surface of seal space 99 is less than the atmospheric pressure acted on the second surface relative with first surface, and when the pressure difference that the second spool 25 of suction valve is subject to is greater than the Adhesion force between the second spool 25 and plug 131, second spool 25 of suction valve departs from tacky state with plug 131, and suction valve is opened.
To move and after Decompression valves and suction valve all being opened, electromagnetic oscillation pump 10 enters normal working when plug 131 and Sealing 23 back and forth shake in the center hole of valve body 11.Plunger 13 to-and-fro motion can suck water from water intake 151, then opens suction valve and be pushed in seal space 99 by water, and then opens Decompression valves and water released seal space 99 and discharges from the water outlet 111 of valve body 11.Like this, the object exporting high-pressure liquid (such as water) is reached by the to-and-fro motion of plunger 13.
The electromagnetic oscillation pump 10 of the utility model embodiment, relative to prior art, Sealing 23 to be arranged on plug 131 and with plug 131 synchronously to-and-fro motion in the center hole of valve body 11, thus change the volume of seal space 99 to a greater degree.When plug 131 displacement distance is shorter, the volume-variation amount of seal space 99 is also larger, thus the pressure that the second spool 25 of the first spool 24 of Decompression valves and suction valve is subject to is larger, more easily departing from tacky state, ensureing that electromagnetic oscillation pump 10 still can successfully enter normal working state through transporting for a long time, after the link such as storage.
The electromagnetic oscillation pump 10 of the utility model embodiment, relative to prior art, owing to being the pressure that the second spool 25 of the first spool 24 or suction valve that change Decompression valves by the mass volume change of seal space 99 is subject to, do not occur directly to contact between first spool 24 of Decompression valves and the second spool 25 of suction valve, thus the first spool 24 of Decompression valves requires low with the relative position of the second spool 25 of suction valve, therefore the electromagnetic oscillation pump 10 of the utility model embodiment can not cause losing efficacy because the first spool 24 of Decompression valves and the relative position of the second spool 25 of suction valve are inaccurate, ensure that the validity of electromagnetic oscillation pump 10 better, reduce the maintenance rate of electromagnetic oscillation pump 10, greatly save cost.Form gap between first spool 24 of Decompression valves and the second spool 25 of suction valve and do not occur all the time directly to contact, can not there is frictional loss in the first spool 24 of Decompression valves and the second spool 25 of suction valve, extend working life each other.
Although be described the utility model with reference to preferred embodiment, when not departing from scope of the present utility model, various improvement can be carried out to it and parts wherein can be replaced with equivalent.Especially, only otherwise there is structural hazard, the every technical characteristics mentioned in each embodiment all can combine in any way.The utility model is not limited to specific embodiment disclosed in literary composition, but comprises all technological schemes fallen in the scope of claim.
