[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] Reference Figures 1-8 A self-holding low-power solenoid valve includes a lower valve body 1, with an inlet 24 at the bottom of one end of the lower valve body 1, allowing gas to enter through the inlet 24 and achieve heat dissipation through gas circulation. A middle valve body 6 is fixed to the top of the lower valve body 1, and a side end cap 17 is fixed to one end of the middle valve body 6, so that the middle valve body 6 can be closed to the side through the side end cap 17. An upper valve body 10 is fixed to the top of the middle valve body 6, and an electromagnet end cap 13 is provided inside the top of the upper valve body 10 for closing the top of the upper valve body 10. The lower valve body 1 has a valve seat through hole 23 inside, and the position of the valve seat through hole 23 overlaps with the axis of the lower valve body 1. The bottom of the valve seat through hole 23 is connected to the inlet 24, so that the gas in the inlet 24 can enter the valve seat through hole 23 and flow inside. The lower valve body 1 has a valve cavity 20 inside and at the top of the valve seat through hole 23, so that the diameter of the valve cavity 20 is larger than the diameter of the valve seat through hole 23, and the valve cavity 20 is connected to the valve seat through hole 23, so that the gas in the valve seat through hole 23 can enter the valve cavity 20. The other end of the lower valve body 1 has an outlet 2 inside and at the top of the inlet 24, and the outlet 2 is connected to the valve cavity 20, so that the gas inside the valve seat through hole 23 can enter the outlet 2 and be discharged through the valve cavity 20. The air circulation is achieved by the air intake of the inlet 24 and the air exhaust of the outlet 2. A valve seat 22 is fixed inside the valve cavity 20 and on the outer side of the top of the valve seat through hole 23, so that sealing and positioning can be achieved through the contact of the sealing packing 21 with the valve seat 22. A valve core 4 is slidably connected inside the valve cavity 20. The valve core 4 has a T-shaped cross section. A sealing packing 21 is fixed at the bottom of the valve core 4 and at the position corresponding to the valve seat through hole 23, so that the descent of the valve core 4 can close the top of the valve seat through hole 23 through the sealing packing 21. A sealing ring 5 is provided inside the top of the outer side of the valve core 4, so that the sealing effect of the valve core 4 can be increased by adjusting the valve core 4 inside the valve cavity 20. A first spring 3 is sleeved on the outer side of the valve core 4, and the bottom of the first spring 3 is fixed to the lower valve body 1, so that when the valve core 4 is squeezed and moved downward, it drives the first spring 3 to compress. Preferably, a valve core connection hole 41 is provided inside the top of the valve core 4, so that it can cooperate with the card seat 7 through the valve core connection hole 41. A valve core boss 43 is fixed on the outside of the valve core 4 and at the bottom of the sealing ring 5. A sealing ring groove 42 is formed on the outside of the valve core 4 and at the top of the valve core boss 43. The sealing ring 5 and the valve core 4 are fixed through the sealing ring groove 42, so that the position of the sealing ring 5 can be positioned and the sealing ring 5 can be prevented from falling off when the valve core 4 moves up and down inside the valve cavity 20.
[0022] The middle valve body 6 has a central through hole 61 inside, which allows the retainer 7 to be raised and lowered within the central through hole 61. A tenon cavity 62 is provided inside one side of the middle valve body 6. The middle valve body 6 has a first tenon through hole 63 and a second tenon through hole 64 arranged sequentially from top to bottom inside the middle valve body 6. These holes are used to connect the central through hole 61 and the tenon cavity 62, so that the Y-shaped tenon 19 can be adjusted in position within the first tenon through hole 63 and the second tenon through hole 64 by moving within the tenon cavity 62. A Y-shaped tenon 19 is installed inside the tenon cavity 62. The Y-shaped tenon 19 includes a first tenon 191 and a second tenon 192. The first tenon 191 is slidably connected to the side end cover 17 and to the first tenon through hole 63, so that the movement of the first tenon 191 can extend out of the side end cover 17. A second spring 18 is sleeved on the outside of the first tenon 191, so that when the first tenon 191 extends out of the side end cover 17, it can drive the second spring 18 to compress, and the movement of the first tenon 191 is limited by the position of the second spring 18 by the second tenon 192. The bottom of the first tenon 191 is fixed with the second tenon 192, and the second tenon 192 is slidably connected to the second tenon through hole 64, so that the first tenon 191 inside the first tenon through hole 63 and the second tenon 192 inside the second tenon through hole 64 can drive the Y-shaped tenon 19 to move synchronously. A retaining seat 7 is slidably connected inside the central through hole 61 of the valve body. The retaining seat 7 includes a retaining seat sliding shaft 71, a retaining seat boss 72, a retaining seat inclined platform 74, and a retaining seat connecting boss 75. The retaining seat boss 72 is fixed to the outside of the retaining seat sliding shaft 71. The retaining seat inclined platform 74 is fixed to the outside of the retaining seat sliding shaft 71 and located at the bottom of the retaining seat boss 72. An inclined surface is formed on the outer side of the bottom of the retaining seat inclined platform 74, which can be driven to rise by pressing the inclined surface of the retaining seat inclined platform 74. The outer side is located between the card seat boss 72 and the card seat inclined platform 74, and the card seat groove 73 is slidably connected to the second tenon 192, so that the second tenon 192 can enter the card seat groove 73 under the action of the second spring 18. The bottom of the card seat sliding shaft 71 is fixed with the card seat connecting boss 75, and the card seat connecting boss 75 is slidably connected to the valve core connecting hole 41, so that the movement of the valve core 4 can drive the card seat 7 to rise, and at the same time, the height of the valve core 4 can be limited by the card seat 7. A sliding sleeve 8 is slidably connected inside the central through hole 61 of the valve body and at the top of the card seat 7. A central hole 82 is opened inside the bottom end of the sliding sleeve 8. The central hole 82 is slidably connected to the sliding shaft 71 of the card seat, so that the sliding sleeve 8 can slide and adjust its height position at the top of the sliding shaft 71 of the card seat through the central hole 82. A sliding sleeve connecting hole 81 is opened inside the top end of the sliding sleeve 8. A connecting rod 9 is slidably connected inside the sliding sleeve connecting hole 81. The connecting rod 9 is inverted T-shaped, so that the rise of the connecting rod 9 can drive the sliding sleeve 8 to rise. A sliding sleeve inclined platform 83 is fixed on the outside of the sliding sleeve 8, so that the rise of the sliding sleeve 8 can press the first tenon 191 through the sliding sleeve inclined platform 83. An electromagnet housing 11 is fixed inside the top of the upper valve body 10. An armature 14 is provided inside the electromagnet housing 11. The bottom of the armature 14 is fixed to the connecting rod 9, so that the armature 14 can be adjusted up and down inside the electromagnet housing 11. A coil bracket 15 is fixed inside the electromagnet housing 11 and outside the armature 14, so that the armature 14 can only be adjusted up and down by the limit of the coil bracket 15. A first coil 12 is wound around the top of the outer side of the coil bracket 15, and a second coil 16 is wound around the outer side of the bottom end of the coil bracket 15. Thus, an external device can drive one of the first coil 12 or the second coil 16 to work as needed.
[0023] The self-holding low-power solenoid valve provided by this invention is used as follows: Initially, both solenoid coils are de-energized, and the solenoid valve is in the open state. Figure 1 As shown, under the action of the first spring 3, the valve core 4 lifts the connected retainer 7, making it tightly contact the sliding sleeve 8 and fixing it in the upper position; at this time, under the action of the sliding sleeve 8, the first tenon 191 of the Y-shaped retainer 19 is in the retracted position, and the second tenon 192 connected to it is also in the retracted state. The sliding sleeve 8 is connected to the armature 14 through the connecting rod 9, pushing the armature 14 to the upper position.
[0024] When the second coil 16 is energized, the armature 14 moves downward under the action of electromagnetic force, moving the sliding sleeve 8, the retainer 7, and the valve core 4 downward together; when the sealing packing 21 at one end of the valve core 4 contacts the valve seat 22, blocking the central through hole of the valve seat 22, the valve is in the closed state. Figure 2 As shown; at this time, the position of the sliding sleeve 8 is such that it is no longer in contact with the Y-shaped latch 19. The Y-shaped latch 19 extends under the action of the second spring 18, and the second tenon 192 is inserted into the groove of the card seat 7. Under the action of the second tenon 192, the card seat 7 and the valve core 4 maintain this position, and the valve is in the closed state. At this time, the first coil 12 is de-energized, and the valve can still remain in the closed state.
[0025] When the solenoid valve needs to be opened, the first coil 12 is energized. Under the action of electromagnetic force, the armature 14 will move upward; the sliding sleeve 8 connected to the armature 14 will also move upward. The sliding sleeve 8 and the retaining seat 7 are slidably connected, and the retaining seat 7 remains stationary under the action of the Y-shaped retaining tenon 19. When the sliding sleeve 8 moves upward, its inclined platform will act on the first tenon 191 of the Y-shaped retaining tenon 19, pushing it back to the retracted position. At this time, the second tenon 192 also retracts, and the retaining seat 7 loses the constraint of the second tenon 192. Under the action of the first spring 3 at the valve core 4, it moves upward together with the valve core 4. After the valve core 4 is lifted, the solenoid valve is in the open state. At this time, the first coil 12 can be de-energized, and the solenoid valve can still remain in the open state.
[0026] By repeatedly energizing and de-energizing the electromagnetic coil, the solenoid valve can be switched between open and closed states. Furthermore, the coil only needs to be energized during the solenoid valve state switching; after the switching is complete, the coil can be de-energized without affecting the valve's state, thus reducing power consumption.
