Embodiment
Below in conjunction with Figure of description, the utility model is described in more detail.As shown in Figure 1, the electromagnetism drain valve that the utility model provides, comprises valve body, spool 2, elastic member, water intake 22, water outlet 21, electromagnetic coil 9.Wherein, valve body comprises the first cylinder 11 and the second cylinder 12; The first cylinder 11 comprises that the first cylindrical shell 111 and the first capping 112, the first cappings 112 are fixed on one end of the first cylindrical shell 111 by welding or integrated mode; The second cylinder 12 comprises that the second cylindrical shell 121 and the second capping 122, the second cappings 122 are fixed on one end of the second cylindrical shell 121 by welding or integrated mode.The first cylindrical shell 111 is not fixed with one end that one end of the first capping 112 and the second cylindrical shell 121 be not fixed with the second capping 122 and 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.
Spool 2 is located at described cavity 10 inside, and spool 2 comprises that switch part 32 is near the first capping 112 by welding or integrated mode connecting valve portion 32 and electromagnetic power portion 31 successively, and can in the first cylindrical shell 111, do piston movement.
Elastic member is fixed between spool 2 and described the first capping 112; The elastic member here can have multiple design.As shown in Figure 1, elastic member is spring 41, and one end of spring 41 props up the end of spool 2, and the other end props up the first capping 112; As shown in Figure 2, spool 2 can inwardly be offered the 3rd groove 312 vertically near one end of the first capping 112, and one end of spring 41 is placed in the 3rd groove 312, and with bottom butt, the other end of spring 41 and first capping 112 butts of the 3rd groove 312.As shown in Figure 3, elastic member can also be the magnet that a pair of homopolarity is oppositely arranged, formed by the first magnet 42 and the second magnet 43, 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 first capping 112 side relative with spool 2 by the mode such as pasting or inlay, and the second magnet 43 is fixed on spool 2 one end near the first capping 112 by the mode such as pasting or inlay.
Shown in electromagnetic coil 1-3, be fixed on the second cylindrical shell 121 inside, around electromagnetic power portion 31.
As shown in Figures 1 to 3, switch part 32 comprises closure part 321 and throughput 322, and throughput 322 is between closure part 321 and electromagnetic power portion 31, and the company's part mode between throughput 322, closure part 321 and electromagnetic power portion 31 all can adopt welding or one-body molded.The shape of throughput 322 can be circle first groove 3221 of offering along the hoop of spool 2, in the time that throughput 322 moves between water intake 22 and water outlet 21, can not cut off being communicated with of water intake 22 and water outlet 21, current can be entered in cavity 10 by water intake 22, the first groove 3221 of the hoop of the throughput of flowing through 322, is discharged by water outlet 21.The shape of throughput 322 can also be as shown in Figure 4, the second penetrating groove 3222 of radially offering on spool 2, in the time that throughput 322 moves between water intake 22 and water outlet 21, can not cut off being communicated with of water intake 22 and water outlet 21, but water intake 22, water outlet 21 are connected with throughput, current are entered by water intake 22, and the throughput 322 of flowing through, is discharged by water outlet 21.
As shown in Figure 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 22 and water outlet 21, closure part 321 has cut off the connection between water intake 22 and water outlet 21 completely, and current can not flow to water outlet 21 from water intake 22.
As shown in Figure 1-2, 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 22 and water outlet 21, water intake 22 and water outlet 21 are in connected state, and current can flow to water outlet 21 through throughput 322 by water intake 22.It is pointed out that in the time that elastic member is spring 41, because spool 2 has the 3rd groove 312, in the time that spool 2 moves to the first capping 112, spring 41 is pressed in the 3rd groove 312 gradually, in the time that electromagnetic power portion 31 props up the second capping 122, just stops.Now, spring 41 is compressed in the 3rd groove 312 completely.Therefore, in this case, the outer wall of the 3rd groove 311 has also played the function of location, has effectively ensured that spool 2 can not slide excessive.
In process from closed condition to opening state, spool 2 moves in cavity 10.The described electromagnetism drain valve of the utility model, coordinate electrical switch to use together, in the time that electromagnetic coil 9 is switched on, electromagnetic power portion 31 is subject to magnetic field induction pushing switch portion and slides to the direction of the first capping 112, and then slided in closure part 321 from the direction to the first capping 112 between water intake 22 and water outlet 21,322 of throughput slide between water intake 22 and water outlet 21, and now, elastic member is in compressive state.Now, 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 be to spool 2 to the first capping 112 direction shift motion negative pressure, thereby cause spool 2 to move to the first capping 112 directions smoothly.Therefore, in the first capping 112, offer penetrating relief opening 5.
In the time that 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 second capping 122.Now, throughput 322 is from moving to the second capping 122 directions between water intake 22 and water outlet 21.Meanwhile, closure part 321 moves between water intake 22 and water outlet 21.So far, closure part 321 cuts off the connection of water intake 22 and water outlet 21, valve closes completely.
Owing to being that the connection that relies on closure part 321 to cut off completely between water intake 22 and water outlet 21 realizes throttle down, therefore, should ensure that the gap between closure part 321 and the first cylindrical shell 111 should be as much as possible little.Therefore, on the first cylindrical shell 111 inwalls, be covered with seal ring 8.
On the first valve body 11, also offer third through-hole 23, spool 2 offers breach 24, and at water intake 22 and water outlet 21, during in closed condition, third through-hole 23 and breach 24 and water outlet 21 are in connected state.This design can during in closed condition, be released the pressure of water outlet 21 1 sides at water intake 22 and water outlet 21 by third through-hole 23.
More than statement is only optimal way of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of 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.
