Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
See shown in Fig. 1-2, single spool magnetic valve, comprising: solenoid valve body 1, is installed on the piston component 2 of solenoid valve body 1 inside, and is arranged at the electromagnetic coil assembly outside solenoid valve body 1.
The inner cavity 10 that forms of described solenoid valve body 1, the upper end of solenoid valve body 1 is formed with a junction 8, between connecting portion 8 and solenoid valve body 1, seal by seal washer 81, piston component 2 is installed in cavity 10, in solenoid valve body 1, be provided with inlet pipeline 11 and outlet conduit, inlet pipeline 11 is communicated with outlet conduit; Outlet conduit comprises: the first body 12 and the second body 13, the first bodys 12 and the second body 13 distribute up and down in cavity 10 two ends. Particularly, inlet pipeline 11 and the first body 12 take shape on connecting portion 8, and inlet pipeline 11 has one section of body parallel, that stretch out connecting portion 8 with the first body 12, are convenient to and outside equipment connection. Described electromagnetic coil assembly comprises: iron core, coil groups 6 and metallic support 7, and iron core is connected with piston component 2, and coil groups 6 is arranged at outside solenoid valve body 1, and metallic support 7 covers at outside coil groups 6. Piston component 2 movement under the magneticaction of electromagnetic coil assembly is carried out shutoff to the beginning of the first body 12 or the second body 13, and the lower end of solenoid valve body 1 is provided with the first member 3 for the second body sealing or drainage corresponding to the second body 13 places.
Embodiment mono-:
As shown in Figure 3, described piston component 2 comprises: be installed on piston rod 21 and back-moving spring 22 in cavity 10, back-moving spring 22 one end are supported on the end of piston rod 21, and the other end is supported on the top of the first member 3; The upper and lower side of piston rod 21 is provided with sealed core 23 corresponding to the beginning of the first body 12 and the second body 13. Between the inwall of piston rod 21 and cavity 10, be formed with passage 14, between inlet pipeline 11, the first body 12 and the second body 13, be communicated with by passage 14.
The first described member 3 is sealing steel core; The first member 3 has the main body 31 in solenoid valve body of being installed on 1 and stretches out the extension 32 outside solenoid valve body 1, the first member 3 is from bottom to top installed in cavity 1O and is positioned at the end of solenoid valve body 1, and main body 31 is sheathed on the second body 13 ends to carry out shutoff. Between first member 3 its main bodys 31 and cavity 10 inwalls, be provided with seal washer, between extension 32 and solenoid valve body 1, be provided with seal washer 5.
Under original state, piston rod 21 moves under the elastic force effect of back-moving spring 22, makes the upper end of piston rod 21 be supported on the beginning of the first body 12, and by sealed core 23, the first body 12 is sealed to setting. When inlet pipeline 11 feed liquor, because the first body 12 is sealed, the first body 12 cannot circulate, and liquid stream flows to the second body 13 along passage 14, but due to the sealed steel core sealing of the second body 13, also cannot discharge from the second body 13. In the time that electromagnetic coil assembly comes into operation, the elastic force that electromagnetic coil assembly generation magnetic field makes piston rod 21 overcome back-moving spring 22 moves down, and make the beginning of low end bearing and second body 13 of piston rod 21, now, the first body 12 is opened, and liquid flows out from the first body 12, when electromagnetic coil assembly quits work, piston rod 21 moves under the restoring force effect of back-moving spring 22, and again the first body 12 is sealed. So, by the magneticaction of electromagnetic coil assembly, piston rod 21 circulations are moved up and down.
Embodiment bis-:
As shown in Figure 4, described piston component 2 comprises: be installed on piston rod 21 and back-moving spring 22 in cavity 10, back-moving spring 22 one end are supported on the end of piston rod 21, and the other end is supported on the top of the first member 3; The upper and lower side of piston rod 21 is provided with sealed core 23 corresponding to the beginning of the first body 12 and the second body 13. Between the inwall of piston rod 21 and cavity 10, be formed with passage 14, between inlet pipeline 11, the first body 12 and the second body 13, be communicated with by passage 14.
The first described member 3 is drainage tube; The first member 3 has the main body 33 in solenoid valve body of being installed on 1 and stretches out the extension 34 outside solenoid valve body 1, on extension 34, offer the passage 15 connecting with the second body 13, between first member 3 its main bodys 33 and cavity 10 inwalls, be provided with seal washer, between extension 34 and solenoid valve body 1, be also provided with seal washer 5.
Under original state, piston rod 21 moves under the elastic force effect of back-moving spring 22, makes the upper end of piston rod 21 be supported on the beginning of the first body 12, and by sealed core 23, the first body 12 is sealed to setting. when inlet pipeline 11 feed liquor, because the first body 12 is sealed, the first body 12 cannot row be located liquid, and liquid runs down passage 14 flows to the second body 13, outwards flows out successively through the second body 13 and passage 15. in the time that electromagnetic coil assembly comes into operation, the elastic force that electromagnetic coil assembly generation magnetic field makes piston rod 21 overcome back-moving spring 22 moves down, and make the beginning of low end bearing and second body 13 of piston rod 21, now, the second body 13 is sealed, and the first body 12 is opened, liquid flows out from the first body 12, when electromagnetic coil assembly quits work, piston rod 21 moves under the restoring force effect of back-moving spring 22, and again the first body 12 is sealed, liquid pumps from the second body 13, so by the magneticaction of electromagnetic coil assembly, piston rod 21 circulations are moved up and down, to realize the two-way circulation at intermittence of the first body 12 and the second body 13 above-below directions.
Certainly, the foregoing is only specific embodiment of the utility model, be not to limit the utility model practical range, all according to equivalence variation or modification that described in the utility model claim, structure, feature and principle are done, all should be included in the utility model claim.
