进一步地，电磁截止阀还包括第二弹性件71，第二弹性件71设置在定铁芯20和动铁芯50之间，第二弹性件71的一端与定铁芯20连接，第二弹性件71的另一端与动铁芯50连接且位于第四孔段21内。如此设置，在运行时，第二弹性件71的弹力可作用在动铁芯50上，以使动铁芯50处于打开阀口102的位置，从而能够实现开阀功能。其中，第二弹性件71具体为复位弹簧，如此设置不仅生产成本低，同时结构简单、重量轻，从而有利于实现装置的轻量化。Further, the electromagnetic stop valve also includes a second elastic member 71. The second elastic member 71 is disposed between the fixed iron core 20 and the moving iron core 50. One end of the second elastic member 71 is connected to the fixed iron core 20. The second elastic member 71 is connected to the fixed iron core 20. The other end of the member 71 is connected to the moving iron core 50 and is located in the fourth hole section 21 . With this arrangement, during operation, the elastic force of the second elastic member 71 can act on the moving iron core 50 so that the moving iron core 50 is in a position to open the valve port 102, thereby realizing the valve opening function. Among them, the second elastic member 71 is specifically a return spring. Such an arrangement not only has low production cost, but also has a simple structure and light weight, which is beneficial to achieving lightweighting of the device.

具体地，电磁截止阀还包括第三密封件72，第三密封件72围设在阀芯60的第二段62的靠近阀口102的外周，第三密封件72可与阀体10内壁配合以密封阀口102。通过设置上述结构，第三密封件72能够对阀口102进行封堵，以实现阀芯60的第二端的和阀口102的连接处的径向密封，如此能够有效地降低装置的内漏，从而提高了装置的密封效果。Specifically, the solenoid stop valve also includes a third seal 72 , which is located around the outer periphery of the second section 62 of the valve core 60 close to the valve port 102 . The third seal 72 can cooperate with the inner wall of the valve body 10 To seal the valve port 102. By arranging the above structure, the third seal 72 can block the valve port 102 to achieve radial sealing at the connection between the second end of the valve core 60 and the valve port 102, which can effectively reduce the internal leakage of the device. Thereby improving the sealing effect of the device.

在本实施例中，阀芯60的第二段62的外周上环形设置有凹槽，第三密封件72设置在环形凹槽内，通过设置上述结构，能够使第三密封件72的安装和拆卸更为简便，同时上述结构也便于加工，从而进一步降低了装置的生产成本。另外，由于阀口102采用该种径向密封设置可以更好地实现阀芯60上下受力面积相同，减小阀芯60上下压力差，从而更容易实现阀芯60两端的压力平衡，减小开阀阻力。In this embodiment, an annular groove is provided on the outer circumference of the second section 62 of the valve core 60, and the third sealing member 72 is disposed in the annular groove. By arranging the above structure, the installation and installation of the third sealing member 72 can be achieved. Disassembly is easier, and the above structure is also easy to process, thereby further reducing the production cost of the device. In addition, since the valve port 102 adopts this kind of radial sealing arrangement, the upper and lower force-bearing areas of the valve core 60 can be better realized to be the same, and the pressure difference between the upper and lower parts of the valve core 60 can be reduced, thereby making it easier to achieve pressure balance at both ends of the valve core 60 and reducing the Valve opening resistance.

如图3至图5所示，本申请实施例三提供了一种电磁截止阀，其包括阀体10、定铁芯20和动铁芯组件30，动铁芯组件30包括动铁芯50和阀芯60。其中，阀体10具有容纳腔101和阀口102，阀口102设置在阀体10的一端并与容纳腔101连通。定铁芯20设置在容纳腔101内，且与阀口102相对设置。动铁芯50可移动地设置在容纳腔101内，动铁芯50的第一端与定铁芯20磁力配合，动铁芯50的第二端朝向阀口102设置。阀芯60位于容纳腔101内，且阀芯60可移动地设置在动铁芯50的第二端，阀芯60用于开启或者封堵阀口102，当动铁芯50向远离阀口102移动的过程中，阀芯60具有静止状态和随动铁芯50同步移动的运动状态。其中，动铁芯50具有沿阀口102至定铁芯20的方向设置的初始位置、配合位置和吸附位置，当动铁芯50处于初始位置时，阀芯60处于静止状态，当动铁芯50移动至配合位置后，阀芯60与动铁芯50同步移动，直至动铁芯50移动至吸附位置。As shown in Figures 3 to 5, the third embodiment of the present application provides an electromagnetic stop valve, which includes a valve body 10, a fixed iron core 20 and a moving iron core assembly 30. The moving iron core assembly 30 includes a moving iron core 50 and Spool 60. The valve body 10 has a receiving cavity 101 and a valve port 102. The valve port 102 is provided at one end of the valve body 10 and communicates with the receiving cavity 101. The stator core 20 is disposed in the accommodation cavity 101 and is disposed opposite to the valve port 102 . The moving iron core 50 is movably arranged in the accommodation cavity 101 . The first end of the moving iron core 50 is magnetically matched with the fixed iron core 20 , and the second end of the moving iron core 50 is arranged toward the valve port 102 . The valve core 60 is located in the accommodation cavity 101, and the valve core 60 is movably disposed at the second end of the moving iron core 50. The valve core 60 is used to open or block the valve port 102. When the moving iron core 50 moves away from the valve port 102 During the movement, the valve core 60 has a static state and a moving state in which the follower core 50 moves synchronously. Among them, the moving iron core 50 has an initial position, a matching position and an adsorption position set along the direction from the valve port 102 to the fixed iron core 20. When the moving iron core 50 is in the initial position, the valve core 60 is in a stationary state. When the moving iron core After 50 moves to the matching position, the valve core 60 and the moving iron core 50 move synchronously until the moving iron core 50 moves to the adsorption position.

应用本申请的技术方案，开阀时，在动铁芯50由初始位置移动至配合位置的过程中，阀芯60保持静止，且此时动铁芯50不需要克服阀芯60受到的压差力，直至动铁芯50带动阀芯60同步移动时，才需要克服阀芯60的压差力。具体地，开阀时，动铁芯50在电磁力的作用下向靠近定铁芯20的方向移动，当动铁芯50移动至配合位置后，动铁芯50带动阀芯60同步向靠近定铁芯20的方向移动，直至动铁芯50移动至吸附位置，阀芯60完全打开阀口102。 由于动铁芯50与定铁芯20之间的电磁力与二者之间的间距呈指数变化的关系，动铁芯50与定铁芯20之间的间距越小，二者之间的磁力越大。因此，动铁芯50处于配合位置处的磁力远大于动铁芯50处于初始位置处的磁力。传统的技术方案中，阀芯60始终与动铁芯50同步移动，因此，在开阀时，动铁芯50在初始位置时就需要克服阀芯60的压差力，但是在初始位置时，动铁芯50与定铁芯20之间的电磁力较小，因此，传统技术方案中的开阀难度较大。与传统的技术方案相比，本方案的设置，能够增加驱动阀芯60移动时刻的电磁力，提升了开阀的顺畅性。并且，本方案通过阀芯60直接控制阀口102的开启以及闭合，结构简单。Applying the technical solution of this application, when the valve is opened, the valve core 60 remains stationary during the movement of the moving iron core 50 from the initial position to the matching position, and at this time, the moving iron core 50 does not need to overcome the pressure difference experienced by the valve core 60 It is not until the moving iron core 50 drives the valve core 60 to move synchronously that the pressure difference force of the valve core 60 needs to be overcome. Specifically, when the valve is opened, the moving iron core 50 moves toward the fixed iron core 20 under the action of electromagnetic force. When the moving iron core 50 moves to the mating position, the moving iron core 50 drives the valve core 60 to move closer to the fixed iron core 20 synchronously. The direction of the iron core 20 moves until the moving iron core 50 moves to the adsorption position and the valve core 60 completely opens the valve port 102. Since the electromagnetic force between the moving iron core 50 and the fixed iron core 20 has an exponential relationship with the distance between them, the smaller the distance between the moving iron core 50 and the fixed iron core 20 , the greater the magnetic force between them. The bigger. Therefore, the magnetic force of the moving iron core 50 in the mated position is much greater than the magnetic force of the moving iron core 50 in the initial position. In the traditional technical solution, the valve core 60 always moves synchronously with the moving iron core 50. Therefore, when the valve is opened, the moving iron core 50 needs to overcome the pressure difference force of the valve core 60 in the initial position. However, in the initial position, The electromagnetic force between the moving iron core 50 and the fixed iron core 20 is small, so it is difficult to open the valve in the traditional technical solution. Compared with the traditional technical solution, the setting of this solution can increase the electromagnetic force driving the movement of the valve core 60 and improve the smoothness of valve opening. Moreover, this solution directly controls the opening and closing of the valve port 102 through the valve core 60, and has a simple structure.

如图3和图4所示，初始位置至配合位置之间的间距为H1，初始位置至吸附位置之间的间距为H，2％H≤H-H1≤20％H。在对动铁芯50和阀芯60进行加工时会有加工误差，并且，对动铁芯50和阀芯60进行装配时会有装配误差，当H-H1≤2％H时，可能存在实际工况中H1大于H的情况，进而可能出现无法开阀的情况。当H-H1≥20％H时，当动铁芯50移动至配合位置后，动铁芯50与定铁芯20之间的间隙过大，可能会影响开阀效果。因此，本申请将H-H1设置在上述范围内，能够进一步提升开阀过程的顺畅性。可选地，H-H1＝2％H、H-H1＝5％H、H-H1＝6％H、H-H1＝8％H、H-H1＝10％H、H-H1＝15％H或者H-H1＝20％H，本方案中，H-H1＝5％H。As shown in Figures 3 and 4, the distance between the initial position and the fitting position is H1, and the distance between the initial position and the adsorption position is H, 2%H≤H-H1≤20%H. There will be processing errors when processing the moving iron core 50 and the valve core 60, and there will be assembly errors when assembling the moving iron core 50 and the valve core 60. When H-H1≤2%H, there may be actual If H1 is greater than H under working conditions, the valve may not be able to open. When H-H1≥20%H, when the moving iron core 50 moves to the matching position, the gap between the moving iron core 50 and the fixed iron core 20 is too large, which may affect the valve opening effect. Therefore, this application sets H-H1 within the above range, which can further improve the smoothness of the valve opening process. Alternatively, H-H1=2%H, H-H1=5%H, H-H1=6%H, H-H1=8%H, H-H1=10%H, H-H1=15% H or H-H1=20%H. In this plan, H-H1=5%H.

如图3和图5所示，阀芯60具有穿设孔，动铁芯50的第二端可移动地穿设在穿设孔内，阀芯60与动铁芯50之间设置有限位结构，限位结构用于限制动铁芯50与阀芯60之间的相对位移量。具体地，开阀时，在电磁力的作用下，动铁芯50向靠近定铁芯20的方向移动，直至动铁芯50移动至配合位置，此时限位结构作用在动铁芯50与阀芯60之间，使得阀芯60随动铁芯50同步移动。上述设置，其结构简单。并且将动铁芯50的第二端穿设在穿设孔内，当阀芯60处于封堵阀口的状态时，能够尽可能地降低动铁芯50和阀芯60的整体的高度，进而能够保证电磁截止阀的紧凑性，使得电磁截止阀实现小型化。As shown in Figures 3 and 5, the valve core 60 has a through hole, the second end of the moving iron core 50 is movably installed in the through hole, and a limiting structure is provided between the valve core 60 and the moving iron core 50. , the limiting structure is used to limit the relative displacement between the moving iron core 50 and the valve core 60 . Specifically, when the valve is opened, under the action of electromagnetic force, the moving iron core 50 moves in a direction close to the fixed iron core 20 until the moving iron core 50 moves to the matching position. At this time, the limiting structure acts on the moving iron core 50 and the valve. between the cores 60, so that the valve core 60 moves synchronously with the iron core 50. The above arrangement has a simple structure. And the second end of the moving iron core 50 is inserted into the penetration hole. When the valve core 60 is in the state of blocking the valve port, the overall height of the moving iron core 50 and the valve core 60 can be reduced as much as possible, and then the overall height of the moving iron core 50 and the valve core 60 can be reduced. It can ensure the compactness of the electromagnetic stop valve and achieve miniaturization of the electromagnetic stop valve.

如图4和图5所示，穿设孔包括沿定铁芯20至阀口102的方向阶梯设置的第一穿设孔601和第二穿设孔602，第二穿设孔602的直径大于第一穿设孔601的直径，第一穿设孔601与第二穿设孔602之间形成阶梯面，动铁芯50的第二端具有限位部501，限位部501与阶梯面限位配合，当动铁芯50处于初始位置时，限位部501与阶梯面之间具有间隔，当动铁芯50处于配合位置时，限位部501与阶梯面抵接，动铁芯50通过限位部501与阶梯面配合以带动阀芯60移动。本方案中，限位部501与阶梯面形成限位结构。具体在开阀时，动铁芯50向靠近定铁芯20的方向移动，动铁芯50在由初始位置移动至配合位置的过程中，阀芯60处于静止状态，当动铁芯50移动至配合位置时，限位部501与阶梯面抵接，动铁芯50继续向靠近定铁芯20的方向移动，并且，动铁芯50受到的电磁力足以克服动铁芯50的重力、阀芯60的重力以及阀芯60所受的压差力，此时，动铁芯50带动阀芯60向靠近定铁芯20的方向移动，直至动铁芯50移动至吸附位置。具体地，限位部501的靠近阶梯面的一端的端面与阶梯面之间的间距与动铁芯50的初始位置至配合位置之间的间距相等。如此设置，能够通过限位部501的靠近阶梯面的一端的端面与阶梯面之间的间距反映初始位置至配合位置之间的间距， 当需要调整初始位置至配合位置之间的间距时，通过调整限位部501的靠近阶梯面的一端的端面与阶梯面之间的间距即可，进而能够保证方案的适应性。As shown in FIGS. 4 and 5 , the through holes include a first through hole 601 and a second through hole 602 arranged in steps along the direction from the stator core 20 to the valve port 102 . The diameter of the second through hole 602 is larger than The diameter of the first through hole 601 is a stepped surface formed between the first through hole 601 and the second through hole 602. The second end of the moving iron core 50 has a limiting portion 501, and the limiting portion 501 is limited to the stepped surface. When the moving iron core 50 is in the initial position, there is a gap between the limiting part 501 and the stepped surface. When the moving iron core 50 is in the matching position, the limiting part 501 is in contact with the stepped surface, and the moving iron core 50 passes through The limiting portion 501 cooperates with the stepped surface to drive the valve core 60 to move. In this solution, the limiting part 501 and the stepped surface form a limiting structure. Specifically, when the valve is opened, the moving iron core 50 moves in a direction close to the fixed iron core 20. When the moving iron core 50 moves from the initial position to the matching position, the valve core 60 is in a stationary state. When the moving iron core 50 moves to When in the matching position, the limiting portion 501 is in contact with the step surface, and the moving iron core 50 continues to move in the direction closer to the fixed iron core 20 , and the electromagnetic force received by the moving iron core 50 is enough to overcome the gravity of the moving iron core 50 and the valve core. At this time, the movable iron core 50 drives the spool 60 to move closer to the fixed iron core 20 until the movable iron core 50 moves to the adsorption position. Specifically, the distance between the end surface of the limiting portion 501 close to the step surface and the step surface is equal to the distance between the initial position and the mating position of the moving iron core 50 . With this arrangement, the distance between the initial position and the mating position can be reflected by the distance between the end surface of the stopper 501 close to the step surface and the step surface. When it is necessary to adjust the distance between the initial position and the mating position, the distance between the end surface of the limiting portion 501 close to the step surface and the step surface can be adjusted, thereby ensuring the adaptability of the solution.

如图5所示，动铁芯50上设置有第三平衡通道502，第三平衡通道502的一端贯穿动铁芯50的第一端的端面设置，第三平衡通道502的另一端贯穿动铁芯50的第二端的端面设置，并与穿设孔连通设置。第三平衡通道502的设置，能够使得动铁芯50的两端的压力快速实现内平衡，减少动铁芯50移动过程中受到的阻力，提升阀芯60移动过程的顺畅性。本实施例中，第三平衡通道502的延伸方向与动铁芯50的延伸方向相同。如此设置，能够保证第三平衡通道502对气压的平衡效果。As shown in FIG. 5 , the moving iron core 50 is provided with a third balancing channel 502 . One end of the third balancing channel 502 runs through the end face of the first end of the moving iron core 50 , and the other end of the third balancing channel 502 runs through the moving iron. The end surface of the second end of the core 50 is disposed and communicates with the through hole. The provision of the third balance channel 502 can quickly achieve internal balance of the pressure at both ends of the moving iron core 50 , reduce the resistance encountered during the movement of the moving iron core 50 , and improve the smoothness of the movement of the valve core 60 . In this embodiment, the extension direction of the third balance channel 502 is the same as the extension direction of the moving iron core 50 . Such an arrangement can ensure the balancing effect of the third balancing channel 502 on the air pressure.

进一步地，动铁芯50的侧壁上设置有第二平衡孔503，第二平衡孔503靠近动铁芯50的第一端设置，且第二平衡孔503与第三平衡通道502连通。第二平衡孔503的设置，能够进一步起到平衡气压的作用，动铁芯50与容纳腔101之间的间隙与第二平衡孔503连通，以平衡阀芯60的两端的压力，保证阀芯60移动的顺畅性。本方案对第二平衡孔503的数量不做限制，本实施例中，第二平衡孔503设置有一个，且第二平衡孔503的延伸方向与动铁芯50的延伸方向垂直。Further, a second balance hole 503 is provided on the side wall of the moving iron core 50 . The second balance hole 503 is provided close to the first end of the moving iron core 50 , and the second balance hole 503 is connected with the third balance channel 502 . The setting of the second balance hole 503 can further balance the air pressure. The gap between the moving iron core 50 and the accommodation cavity 101 is connected with the second balance hole 503 to balance the pressure at both ends of the valve core 60 and ensure that the valve core 60 smoothness of movement. This solution does not limit the number of the second balancing holes 503. In this embodiment, one second balancing hole 503 is provided, and the extending direction of the second balancing hole 503 is perpendicular to the extending direction of the moving iron core 50.

如图3和图5所示，电磁截止阀还包括缓冲件91。缓冲件91设置在动铁芯50的第二端与阀芯60之间，缓冲件91的一端与阀芯60连接，缓冲件91的另一端与动铁芯50的第二端连接。本实施例中，缓冲件91为缓冲弹簧，缓冲弹簧套设在动铁芯50的第二端，缓冲弹簧的一端与动铁芯50连接，缓冲弹簧的另一端与阶梯面连接。缓冲弹簧的设置，能够在限位部501与阶梯面接触时起到缓冲的作用，减少限位部501与阶梯面接触的瞬间限位部501作用在阀芯60上的作用力，保证动铁芯50带动阀芯60移动过程的平稳性，同时，也能够减少限位部501的靠近阶梯面的一端的端面以及阶梯面受冲击力过大而发生变形的情况，以保证经过长时间的使用后，初始位置与配合位置之间的间距与出厂时的二者之间的间距尽可能地一致，保证开阀的顺畅性。As shown in FIGS. 3 and 5 , the electromagnetic stop valve also includes a buffer member 91 . The buffering member 91 is disposed between the second end of the moving iron core 50 and the valve core 60 . One end of the buffering member 91 is connected to the valve core 60 , and the other end of the buffering member 91 is connected to the second end of the moving iron core 50 . In this embodiment, the buffer member 91 is a buffer spring. The buffer spring is sleeved on the second end of the moving iron core 50 . One end of the buffer spring is connected to the moving iron core 50 , and the other end of the buffer spring is connected to the step surface. The setting of the buffer spring can play a buffering role when the limiter 501 contacts the step surface, reducing the force of the limiter 501 acting on the valve core 60 at the moment when the limiter 501 contacts the step surface, ensuring that the moving iron The core 50 drives the stability of the movement of the valve core 60. At the same time, it can also reduce the deformation of the end surface of the limiter 501 close to the step surface and the step surface due to excessive impact force, so as to ensure long-term use. Finally, the distance between the initial position and the mating position is as consistent as possible with the distance between the two at the factory to ensure smooth valve opening.

如图5所示，阀芯60包括由定铁芯20至阀口102的方向顺次连接的第三段611、第四段612和第五段613，其中，第三段611的外径与第五段613的外径均大于第四段612的外径，阀体10上还设置有流通孔103，流通孔103与容纳腔101连通设置，当阀芯60处于封堵阀口102的位置时，流通孔103与第四段612相对设置。如此设置，能够减少阀芯60的整体的重量，进而能够减少动铁芯50带动阀芯60移动时需要克服的阀芯60的重力，进一步提升开阀的顺畅性。并且，当阀芯60处于封堵阀口102的位置时，流通孔103与第四段612相对设置。由于第四段612的外径小于第五段613的外径并且第四段612的外径也小于第三段611的外径，如此设置，能够减小阀芯60与流体的接触面积，进而能够减少流体对阀芯60的冲击力，保证阀芯60的稳定性。并且，如此设置，能够增加阀芯60与阀体10的内壁之间的空间，进而能够保证流体的流量，提升流体流通的顺畅性。并且，第三段611和第五段613均与容纳腔101间隙配合，第四段612与阀体10的内壁之间的间隔较大，因此在开阀以及闭阀的过程中，不需要克服第四段612与阀体10的内壁之间的摩擦力，提升了开阀以及闭阀过程的顺畅性。 As shown in FIG. 5 , the valve core 60 includes a third section 611 , a fourth section 612 and a fifth section 613 that are sequentially connected from the stator core 20 to the valve port 102 . The outer diameter of the third section 611 is equal to the outer diameter of the third section 611 . The outer diameter of the fifth section 613 is larger than the outer diameter of the fourth section 612. The valve body 10 is also provided with a flow hole 103. The flow hole 103 is connected to the accommodation cavity 101. When the valve core 60 is in the position of blocking the valve port 102 , the flow hole 103 is arranged opposite to the fourth section 612 . Such an arrangement can reduce the overall weight of the valve core 60, thereby reducing the gravity of the valve core 60 that needs to be overcome when the moving iron core 50 drives the valve core 60 to move, further improving the smoothness of valve opening. Moreover, when the valve core 60 is in the position of blocking the valve port 102, the flow hole 103 is arranged opposite to the fourth section 612. Since the outer diameter of the fourth section 612 is smaller than the outer diameter of the fifth section 613 and the outer diameter of the fourth section 612 is also smaller than the outer diameter of the third section 611, such an arrangement can reduce the contact area between the valve core 60 and the fluid, thereby reducing the contact area between the valve core 60 and the fluid. The impact force of the fluid on the valve core 60 can be reduced and the stability of the valve core 60 can be ensured. Moreover, such an arrangement can increase the space between the valve core 60 and the inner wall of the valve body 10, thereby ensuring the flow rate of the fluid and improving the smoothness of the fluid circulation. Moreover, the third section 611 and the fifth section 613 both have a clearance fit with the accommodating cavity 101, and the distance between the fourth section 612 and the inner wall of the valve body 10 is relatively large. Therefore, there is no need to overcome the problem during the valve opening and closing processes.
