Embodiment
Below in conjunction with Figure of description, the utility model is described in more detail.
As shown in Fig. 1-8, the electromagnetism drain valve that the utility model provides, comprise valve body, spool 2, elastic member, water intake 21, water outlet 22, electromagnetic coil 9.Wherein,
Valve body comprises the first drum shape body 11 and the second drum shape body 12; The first drum shape body 11 comprises that the first cylindrical shell 111 and the first capping 112, the first cappings 112 are fixed in an end of the first cylindrical shell 111 by welding or integrated mode; The second drum shape body 12 comprises that the second cylindrical shell 121 and the second capping 122, the second cappings 122 are fixed in an end of the second cylindrical shell 121 by welding or integrated mode.The first cylindrical shell 111 is not fixed with an end of the first capping 112 and an end that the second cylindrical shell 121 is not fixed with the second capping 122 is connected and fixed, and this means of fixation can be also welding or one-body molded.Now, the first cylindrical shell 111, the second cylindrical shell 121, the first capping 112 and the common formation cavity 10 of the second capping 122.
Between the fixing described electromagnetic power section 31 of elastic member and described the second capping 122; The elastic member here can have multiple design.As shown in Figure 1, elastic member is spring 41, and an end of spring 41 props up electromagnetic power section 31, and the other end props up the second capping 122; As shown in Figure 2, electromagnetic power section 31 can inwardly offer the 3rd groove 311 vertically near an end of the second capping 122, one end of spring 41 is placed in the 3rd groove 311, and with bottom butt, the other end of spring 41 and second capping 122 butts of the 3rd groove 311.As shown in Figure 3, elastic member can also be the magnet that a pair of homopolarity is oppositely arranged, by the first magnet 42 and the second magnet 43, formed, the first magnet 42 and the second magnet 43 are oppositely arranged, and relative face is homopolarity, the first magnet 42 is fixed on the second capping 122 side relative with electromagnetic power section 31 by the mode such as pasting or inlay, and the second magnet 43 is fixed on the end of electromagnetic power section 31 near the second cappings 122 by the mode such as pasting or inlay.
Electromagnetic coil 9 is fixed on the second cylindrical shell 121 inside, around electromagnetic power section 31.
The following different setting method according to water intake 21 and water outlet 22, illustrate that respectively the unlatching of electromagnetism drain valve, closed state change.
Embodiment 1
When water intake 21 and water outlet 22 are all opened on the first cylindrical shell 111, as shown in Figures 1 to 3, switch part 32 comprises closure part 321 and throughput 322, closure part 321 is between throughput 322 and electromagnetic power section 31, and the Placement between throughput 322, closure part 321 and electromagnetic power section 31 all can adopt welding or one-body molded.The shape of throughput 322 can be as shown in Figure 7, the hoop of throughput 322 has circle first groove 3221, when throughput 322 moves between water intake 21 and water outlet 22, can not cut off being communicated with of water intake 21 and water outlet 22, current can be entered in cavity 10 by water intake 21, the first groove 3221 of the hoop of the throughput of flowing through 322, discharged by water outlet 22.The shape of throughput 322 also can be as shown in Figure 8, penetrating the second groove 3222 radially having of throughput 322, when throughput 322 moves between water intake 21 and water outlet 22, can not cut off being communicated with of water intake 21 and water outlet 22, but water intake 21, water outlet 22 are connected with the second groove 3222, current are entered by water intake 21, and the second groove 3222 on the throughput of flowing through 322 is discharged by water outlet 22.
As shown in Fig. 1 to 5, electromagnetism drain valve described in the utility model in off position under, elastic member in the raw, now, closure part 321 is between water intake 21 and water outlet 22, closure part 321 has cut off the connection between water intake 21 and water outlet 22 fully, and current can not flow to water outlet 22 from water intake 21.It is worth mentioning that, switch part 32 also is connected with positioning rod 33 near an end of the first capping 112, and positioning rod 33 is one-body molded with spool 2.When the electromagnetism drain shut valve, positioning rod 33 props up the first capping 112, prevents because the elastic force of elastic member is excessive, causes electromagnetic power section 31 excessively to move to the first capping direction, thereby causes electromagnetic power section 31 to break away from induction areas.
As shown in Figure 6, the novel described electromagnetism drain valve of this use is under opening state, elastic member is in compressive state, now, throughput 322 is between water intake 21 and water outlet 22, water intake 21 and water outlet 22 are in connected state, and current can flow to water outlet 22 through throughput 322 by water intake 21.It is pointed out that when elastic member is spring 41, because electromagnetic power section 31 has the 3rd groove 311, when electromagnetic power section 31 moves to the second capping 122, spring 41 is pressed in the 3rd groove 311 gradually, when electromagnetic power section 31 props up the second capping 122, just stops.Now, spring 41 is compressed in the 3rd groove 311 fully.Therefore, in this case, the outer wall of the 3rd groove 311 has also played the function of location, has effectively guaranteed that spool 2 can not slide excessive.
In process from the closed condition to the opening state, spool 2 moves in cavity 10.The described electromagnetism drain valve of the utility model, coordinate electrical switch to use together, when electromagnetic coil 9 energising, electromagnetic power section 31 is subject to magnetic field induction and slides to the direction of the second capping 122, and then slided in closure part 321 from the direction to the second capping 122 between water intake 21 and water outlet 22,322 of throughput slide between water intake 21 and water outlet 22, and now, elastic member is in compressive state.Now, the electromagnetism drain valve is in opening state.In this process, because the first capping 112, closure part 321 and the first cylindrical shell 111 have formed an airtight space jointly, if there is air in this airtight space, can move the formation negative pressure to the second capping 122 directions to spool 2, thereby cause spool 2 to move to the second capping 122 directions smoothly.Therefore, offer penetrating relief opening 5 in the first capping 112.
When electromagnetic coil 9 stops switching on, magnetic field disappears, and under the thrust that spool 2 resets at elastic member, starts to slide to the direction of the first capping 112.Now, throughput 322 is from moving to the first capping 112 directions between water intake 21 and water outlet 22.Simultaneously, closure part 321 moves between water intake 21 and water outlet 22.So far, closure part 321 cuts off the connection of water intake 21 and water outlet 22, valve closes fully.
Owing to being that the connection that relies on closure part 321 to cut off fully between water intake 21 and water outlet 22 realizes throttle down, therefore, should guarantee that the gap between closure part 321 and the first cylindrical shell 111 should be as much as possible little.Therefore, be covered with seal ring 8 on the first cylindrical shell 111 inwalls.
In water intake 21 and water outlet 22, open in the first capping 112 for one, another is opened on the first cylindrical shell 111, or water intake 21 and water outlet 22 are that spool 2 can not arrange throughput 322 with implementing difference in 1 while all opening in the first capping 112.After move to the second capping 122 directions closure part 321, water intake 21 and water outlet 22 are communicated with, and now, after current enter cavity 10 by water intake 21, directly by water outlet 22, are discharged.Be that whole water inlet, drainage procedure all complete in the cavity between closure part 321 and the first capping 112, do not need to be with reeded throughput.
Other working procedure in the present embodiment are all identical with embodiment 1, repeat no more.
Above statement is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, within these also should be considered as protection domain of the present utility model.
