It will be appreciated that in practical use of the solenoid valve, the medium can flow through the outlet port 14 and out of the outlet channel 13 after entering the valve chamber 11 from the inlet channel 12.
The sealing member 30 is used for opening and closing the liquid outlet 14, thereby realizing the basic switching function of the electromagnetic valve. The sealing member 30 includes a sealing portion 31 located inside the valve cavity 11, and the sealing portion 31 is aligned with the liquid outlet port 14, for example, the liquid outlet port 14 may be a flow channel formed inside the valve cavity 11 and in a vertical state, and the sealing portion 31 is disposed on top of the liquid outlet port 14 to seal the liquid outlet port 14.
The electromagnetic assembly 40 is fixedly mounted to the valve body 10 through the mounting plate 20, so that the electromagnetic valve structure is more compact, and the electromagnetic assembly 40 is used for driving the sealing portion 31 to reciprocate to open or close the liquid outlet port 14 through the sealing portion 31, for example, the electromagnetic assembly 40 may be an assembly capable of driving the sealing portion 31 to move through cooperation of electromagnetic force and elastic force, and specific structure of the electromagnetic assembly 40 will be described below.
On this basis, in order to achieve a more rapid and convenient fixed mounting of the solenoid assembly 40 to the valve body 10 by the mounting plate 20, some embodiments of the present application further improve the manner of connection between the valve body 10 and the mounting plate 20.
Specifically, please refer to fig. 4 to 6, wherein fig. 4 shows a schematic structural diagram of an exemplary valve body 10 according to the present application, fig. 5 shows a schematic structural diagram of an exemplary mounting plate 20 according to the present application, and fig. 6 shows a partially enlarged view of the solenoid valve in a sectional state.
As shown in fig. 4, in order to facilitate the installation and fixation of the installation plate 20, the valve body 10 is further provided with an annular installation opening 15 and at least one limiting portion 16, the installation opening 15 is communicated with the valve cavity 11, the installation opening 15 is provided with a first bearing step 17, the limiting portion 16 extends along the circumferential direction of the installation opening 15, for example, the limiting portion 16 may be an arc structure extending along the circumferential direction of the installation opening 15, and the limiting portion 16 is disposed opposite to the first bearing step 17, so that a limiting clamping groove 18 is formed between the single limiting portion 16 and the first bearing step 17.
As shown in fig. 5, the mounting plate 20 may include a main body 21 and a mounting portion 22, where the electromagnetic assembly 40 is connected to the main body 21, the mounting portion 22 is disposed at the bottom of the main body 21, and the mounting portion 22 can be inserted into the mounting opening 15 of the valve body 10, and the outer wall of the mounting portion 22 is further provided with a clamping portion 23 corresponding to the limiting clamping groove 18 one by one, for example, the clamping portion 23 may also have an arc structure extending along the circumferential direction of the mounting opening 15. Meanwhile, in order to improve the reliability of the mounting plate 20 after being mounted and fixed, a plurality of limiting portions 16 may be sequentially disposed at intervals along the circumferential direction of the mounting opening 15 so as to form a plurality of limiting clamping grooves 18, for example, fig. 4 shows the valve body 10 provided with two limiting portions 16 so as to form two limiting clamping grooves 18, and at this time, two clamping portions 23 disposed on the outer wall of the mounting portion 22 correspond to each other.

When the mounting portion 22 is inserted into the mounting opening 15, the clamping portion 23 is carried on the first carrying step 17, and since the freedom of the mounting plate 20 in the horizontal direction is not constrained, the mounting plate 20 can rotate in the horizontal plane relative to the valve body 10 around the axis of the mounting opening 15, so that the mounting plate 20 can be switched between the locking position and the releasing position, and when the mounting plate 20 rotates by a certain angle and is in the locking position, the clamping portion 23 on the mounting portion 22 is just clamped into the corresponding limiting clamping groove 18, at this time, as shown in fig. 6, the freedom of the mounting plate 20 in the vertical direction can be effectively limited under the limiting action of the limiting clamping groove 18, and then the mounting and fixing of the mounting plate 20 are realized.
On the contrary, when the mounting plate 20 needs to be disassembled, the mounting plate 20 only needs to be reversely rotated to enable the clamping part 23 to withdraw from the corresponding limiting clamping groove 18, at this time, the mounting plate 20 is in the release position, and then the mounting plate 20 can be taken out from the mounting port 15 of the valve body 10, so that the operation is simple and convenient.
Therefore, the quick mounting structure provided by the application effectively simplifies the mounting and dismounting process of the mounting plate 20 by improving the connection mode between the valve body 10 and the mounting plate 20, and compared with the connection mode of connecting the mounting plate 20 and the valve body 10 by adopting threaded connection or interference connection, the mounting plate 20 is free from abnormal conditions such as thread sliding, cracking or permanent deformation after being mounted and fixed, and the reliability of the mounting plate 20 after being mounted and fixed is effectively improved, so that the actual use performance of the electromagnetic valve is improved.
In addition to this, in order to further improve the reliability of the mounting plate 20 after mounting and fixing, in some embodiments of the present application, in combination with what is shown in fig. 3, when the mounting portion 22 of the mounting plate 20 is inserted into the mounting port 15 of the valve body 10, the body portion 21 is carried on the end face of the valve body 10 at the mounting port 15. At this time, as shown in fig. 4 and 5, the body 21 is provided with a limiting through hole 24, and the end surface of the valve body 10 at the mounting opening 15 is provided with a locking hole 19 adapted to the limiting through hole 24.
At this time, the quick mounting structure may further include a locking pin (not shown in the drawings), and when the mounting plate 20 is at the locking position, the limit through hole 24 on the body portion 21 is just aligned with the locking hole 19 on the valve body 10, and then the locking pin may be inserted into the aligned limit through hole 24 and locking hole 19 to further fix the mounting plate 20 and the valve body 10.
Next, in some embodiments of the present application, with continued reference to fig. 5, a stop portion 25 may also be provided at an end of each clip portion 23, and when the mounting portion 22 is in the locked position, the stop portion 25 abuts against the corresponding limit portion 16. It can be appreciated that, by the arrangement of the stop portion 25, the operator can further determine whether the mounting plate 20 rotates in place, i.e. whether the clamping portion 23 is clamped into the corresponding limiting slot 18. Of course, in some embodiments of the present application, with continued reference to fig. 4, an observation port 110 that communicates with the mounting port 15 may be further formed on the outer wall of the valve body 10, and the observation port 110 is aligned with the limit clamping groove 18, for example, the observation port 110 may be formed on the circumferential outer wall of the valve body 10 and corresponds to the limit clamping groove 18 one by one, so that whether the clamping portion 23 is clamped into the corresponding limit clamping groove 18 may be further observed through the observation port 110.
To effect a reciprocating movement of the sealing portion 31 of the seal 30 to open or close the outlet port 14 with the electromagnetic assembly 40 fixedly mounted to the mounting plate 20. In some embodiments of the present application, as shown in fig. 5, the mounting plate 20 may further include a channel 26, and the channel 26 penetrates the body portion 21 and the mounting portion 22 sequentially along the axis of the mounting port 15, that is, when the mounting portion 22 is inserted into the mounting port 15, the channel 26, the mounting port 15 and the liquid outlet port 14 are located on the same axis.
Referring to fig. 3, 5 and 7, the electromagnetic assembly 40 may include a sleeve 41, a coil 42, a stationary core 43, a movable core 44 and an elastic member 45. One end of the sleeve 41 passes through the channel 26 and is provided with a connecting portion 411, the connecting portion 411 is annular and extends outwards along the radial direction of the sleeve 41, for example, the connecting portion 411 may be an annular ring integrally formed at the end of the sleeve 41, and one side of the connecting portion 411 facing the mounting portion 22 is provided with at least one protruding block 412, at this time, the bottom surface of the mounting portion 22 is provided with grooves 221 corresponding to the protruding blocks 412 one by one, and the protruding blocks 412 are embedded in the corresponding grooves 221, for example, the protruding blocks 412 may be protrusions formed after the part of the connecting portion 411 is bent upwards, and a plurality of protruding blocks 412 may be arranged along the circumferential direction of the connecting portion 411, for example, the protruding blocks 412 may be three. In this way, a reliable fixed connection of the sleeve 41 to the mounting plate 20 is achieved.
The coil 42 for providing electromagnetic force is wound on the outer wall of the sleeve 41, and the coil 42 can be carried on the body 21 of the mounting plate 20, meanwhile, the static iron core 43 and the moving iron core 44 are both disposed inside the sleeve 41, and the moving iron core 44 is located between the static iron core 43 and the sealing portion 31, at this time, one end of the moving iron core 44 facing the sealing portion 31 is connected with the sealing portion 31. The elastic member 45 is disposed between the movable core 44 and the stationary core 43, and two ends of the elastic member 45 are respectively connected to the movable core 44 and the stationary core 43, for example, the elastic member 45 may be a spring.
So set up, in the initial state, sealing portion 31 seals and closes liquid outlet port 14, and elastic member 45 is in the state of natural extension, will produce electromagnetic force when coil 42 is circular telegram, and at this moment, static iron core 43 will attract movable iron core 44 under the effect of electromagnetic force to drive sealing portion 31 to move towards the direction that keeps away from liquid outlet port 14 through movable iron core 44, and then realize opening liquid outlet port 14, in this process, elastic member 45 compresses in order to prestore an elasticity. Correspondingly, when the coil 42 is de-energized, the electromagnetic force is eliminated, and at this time, the elastic member 45 releases the pre-stored elastic force to force the movable iron core 44 to drive the sealing portion 31 to move towards the direction of the liquid outlet 14, so as to reseal and close the liquid outlet 14 by using the sealing portion 31.
Furthermore, in order to achieve a reliable mounting of the seal 30 into the valve chamber 11, in some embodiments of the application, as shown in fig. 4, a second bearing step 120 is provided inside the valve chamber 11, e.g. the second bearing step 120 may be provided close to the first bearing step 17.
In conjunction with what is shown in fig. 3 and 8, the seal 30 may then further comprise a base portion 32 and a deformation portion 33, wherein the base portion 32 is carried on the second carrying step 120, and a side of the base portion 32 facing away from the second carrying step 120 abuts against the connecting portion 411 of the sleeve 41, so as to achieve reliable confinement of the base portion 32 inside the valve chamber 11 by cooperation of the second carrying step 120 and the connecting portion 411. The deformation portion 33 has deformability, for example, the deformation portion 33 may be made of polytetrafluoroethylene material, and the base portion 32 and the sealing portion 31 are connected through the deformation portion 33, and the end of the movable iron core 44 facing the sealing portion 31 sequentially passes through the base portion 32 and the deformation portion 33 and then is connected with the sealing portion 31.
So configured, when the plunger 44 reciprocates the sealing portion 31, the deformation portion 33 can adapt to the movement of the plunger 44 by its own deformation, while the base portion 32 remains stationary, since the deformation portion 33 has a deformability. Further, in some embodiments of the present application, as shown in fig. 8, the deformation portion 33 may be configured as a corrugated structure with deformation capability, so that when the movable iron core 44 drives the sealing portion 31 to move, the portion of the deformation portion 33 near the sealing portion 31 will deform first, and as the movement stroke of the sealing portion 31 increases, the portion of the deformation portion 33 away from the sealing portion 31 will gradually deform, so that the deformation amount of the whole deformation portion 33 during the movement of the sealing portion 31 can be reduced as much as possible, so that the volume change of the sealing portion 31 inside the valve cavity 11 caused by the sealing member 30 is smaller when the sealing portion 14 is opened or closed, thereby reducing the possibility of occurrence of larger pressure fluctuation of the medium inside the valve cavity 11, which is beneficial to more precisely controlling the amount of the medium flowing out from the outlet port 14.
Meanwhile, in some embodiments of the present application, as shown in fig. 6, a sealing ring 50 is further disposed between the second bearing step 120 and the base portion 32, for example, by disposing a sealing groove in the second bearing step 120 and disposing the sealing ring 50 in the sealing groove, the installation of the sealing ring 50 is further achieved, and thus reliable sealing between the base portion 32 and the second bearing step 120 is achieved, so as to avoid the medium in the valve cavity 11 from flowing out from the gap between the base portion 32 and the second bearing step 120, and improve the tightness of the valve cavity 11.
To achieve reliable retention of the stationary core 43 within the sleeve 41, in some embodiments of the application, as shown in fig. 3, the electromagnetic assembly 40 may further include a lock nut 46, with the lock nut 46 being disposed at an end of the stationary core 43 remote from the plunger 44 to lock the stationary core 43 within the sleeve 41 via the lock nut 46. For example, an external thread sleeve may be sleeved on an end of the stationary core 43 away from the movable core 44 or an external thread may be directly provided on an outer wall of the stationary core 43, so that the lock nut 46 may be connected with the stationary core 43 by means of a threaded connection.
The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
