Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, and specifically relates to a combined electromagnetic valve. Background Technology

[0002] Solenoid valves, as an indispensable key device in the field of industrial automation, are actuators that use electromagnetic effects to achieve fluid control. They are widely used in various fluid control systems such as hydraulics and pneumatics, and can accurately adjust the direction, flow rate, speed and other parameters of the medium. They can be combined with different circuits to achieve diverse control objectives and play an important role in many scenarios such as industrial production and daily life. Currently, solenoid valves can be used in combination.

[0003] For example, Chinese patent CN222783089U discloses an easily detachable and assembleable combined solenoid valve, including a base, a valve body on the surface of the base, a power connection socket on one side of the valve body, and a mounting frame on the bottom of the base; a mounting mechanism on the bottom side of the mounting frame, a limit mechanism inside the mounting frame, and mounting holes on the inner surface of the mounting frame; the mounting mechanism includes a housing, a fixing seat, and a slot, the housing is fixedly installed with the mounting frame, the fixing seat is fixedly installed with the base, and a slot is formed on one side surface of the fixing seat.

[0004] The base of the aforementioned combined solenoid valve can be easily disassembled and assembled, thus enabling the combined solenoid valve to achieve an easy disassembly and assembly effect. However, this device still has some defects that need to be improved. The connection between the base and the mounting frame is achieved by using a spring, a retainer, and a slot. Although this can meet basic disassembly and assembly requirements, it has poor stability under actual complex working conditions. When the solenoid valve is running, the pressure fluctuation of the internal fluid will generate periodic impact forces. The spring is prone to fatigue deformation under frequent stress, which leads to a decrease in the clamping force between the retainer and the slot. In addition, in a vibrating working environment, a small relative displacement will also occur between the retainer and the slot. The continuous accumulation of this displacement can easily cause the connection to loosen. Therefore, improvements are needed. Utility Model Content

[0022] Example

[0023] refer to Figures 1 to 5The combined solenoid valve described in this embodiment includes a base 3, a valve body 1 at the top of the base 3 (multiple valve bodies 1 are provided), a power connector 2 fixedly connected to one side of the valve body 1, a mounting frame 4 fitted to the bottom of the base 3, and docking blocks 6 fixedly connected to both sides of the bottom of the base 3. A docking frame 5 fixedly connected to both sides of the bottom of the mounting frame 4, with one side of the docking block 6 movably connected inside the docking frame 5. A first positioning mechanism 7 is provided between the docking block 6 and the docking frame 5. A disc 11 is fixedly connected to one side, and a second positioning mechanism 8 is provided on one side of the disc 11 near the first positioning mechanism 7. First, the base 3 is placed above the mounting frame 4, so that the mating blocks 6 on both sides of the bottom end of the base 3 are aligned with the mating frames 5 on both sides of the bottom end of the mounting frame 4. The base 3 is slowly lowered, and the mating blocks 6 are gradually inserted into the mating frames 5 to complete the positioning and fitting of the base 3 and the mounting frame 4. Multiple valve bodies 1 are fixedly installed on the top of the base 3, and then the power connector 2 is fixedly connected to one side of the valve body 1 to complete the installation layout of the main components of the combined solenoid valve.

[0024] refer to Figure 2 and Figure 4 The first positioning mechanism 7 includes a first positioning groove 71, which is formed inside the docking block 6. A first positioning block 72 is inserted into the first positioning groove 71. A first slider 73 is fixedly connected to one side of the first positioning block 72. First sliding grooves 75 are formed on both sides of the bottom end of the mounting frame 4. The first slider 73 is slidably connected inside the first sliding groove 75. A first lead screw 74 is rotatably connected inside the first sliding groove 75. A first torsion block 78 is fixedly connected to one side of the first lead screw 74. The first slider 73 is threaded onto the first lead screw 74. The second positioning mechanism 8 is located on one side of the first torsion block 78. By setting the first positioning mechanism 7, when… After the docking block 6 is inserted into the docking frame 5, the first torsion block 78 is rotated, which drives the first lead screw 74 to rotate in the first slide groove 75. Since the first slider 73 is threadedly connected to the first lead screw 74, the rotation of the first lead screw 74 causes the first slider 73 to slide along the first slide groove 75, thereby driving the first positioning block 72 to move. The first positioning block 72 gradually inserts into the first positioning groove 71 inside the docking block 6 until the first positioning block 72 is completely embedded in the first positioning groove 71, thus achieving a firm lock between the base 3 and the mounting frame 4. Compared with the traditional connection method, it can provide a stronger connection and fastening force, effectively resisting the impact force generated by the internal fluid pressure fluctuation and external vibration during the operation of the solenoid valve, and preventing loosening between the base 3 and the mounting frame 4.

[0025] refer to Figure 5The first slide groove 75 has limit grooves 76 on both sides inside. The limit grooves 76 are slidably connected to the inside of the limit blocks 77. One side of the limit blocks 77 is fixedly connected to one side of the first slider 73. By setting the limit grooves 76 and the limit blocks 77, the first slider 73 is effectively prevented from deviating or getting stuck during movement, and is also used to limit the sliding position of the first slider 73.

[0026] refer to Figure 3 The second positioning mechanism 8 includes a fixing block 81, which is fixedly connected to one side of the first torsion block 78. A second sliding groove 82 is formed inside the fixing block 81, and a second slider 83 is slidably connected inside the second sliding groove 82. A second positioning block 84 is fixedly connected to one side of the second slider 83. A second positioning groove 86 is formed on one side of the disc 11, and one side of the second positioning block 84 is movably connected to the second positioning groove 86. A second lead screw 85 is rotatably connected to one side of the second sliding groove 82. The second slider 83 is threaded onto the second lead screw 85, and a second torsion block 87 is fixedly connected to one end of the second lead screw 85. By setting the second positioning mechanism 8, when the first torsion block... After 78 is rotated to its maximum position, the second torsion block 87 is rotated, which drives the second lead screw 85 to rotate in the second slide groove 82, causing the second slider 83 to slide in the second slide groove 82, pushing the second positioning block 84 to move towards the second positioning groove 86 on one side of the disc 11. This prevents the first positioning mechanism 7 from loosening due to accidental rotation of the first torsion block 78. When disassembling, the second torsion block 87 is rotated in the opposite direction to allow the second positioning block 84 to exit from the second positioning groove 86, thus releasing the restriction on the first positioning mechanism 7. The setting of the second positioning mechanism 8 provides double protection for the first positioning mechanism 7, effectively preventing the first torsion block 78 of the first positioning mechanism 7 from loosening due to factors such as equipment vibration and external collision, and avoiding the failure of the connection between the base 3 and the mounting frame 4.

[0027] refer to Figure 2-3 A touch switch 9 is fixedly connected inside the second positioning groove 86. One side of the second positioning block 84 is movably connected to one side of the touch switch 9. A warning light 10 is fixedly connected to one side of the base 3. By setting the touch switch 9 and the warning light 10, when the second positioning block 84 is inserted into the second positioning groove 86, one side of the second positioning block 84 contacts the touch switch 9 inside the second positioning groove 86 and triggers the switch. After the touch switch 9 is triggered, it sends an electrical signal to the warning light 10, causing the warning light 10 to light up, indicating that the second positioning mechanism 8 is installed stably, thereby ensuring that the first positioning mechanism 7 is installed stably.

[0028] Operating principle and advantages: Place the base 3 on top of the mounting frame 4, ensuring that the mating blocks 6 on both sides of the bottom of the base 3 are precisely aligned with the mating frames 5 on both sides of the bottom of the mounting frame 4. Then, slowly lower the base 3, allowing the mating blocks 6 to smoothly insert into the mating frames 5, completing the initial positioning and fitting of the base 3 and the mounting frame 4. Next, fix multiple valve bodies 1 on the top of the base 3 and securely connect the power connector 2 to one side of the valve body 1, completing the installation layout of the main components of the combined solenoid valve. After the mating blocks 6 are inserted into the mating frames 5, rotate the first torsion block 78, causing the first lead screw 74 to rotate within the first slide groove 75. The rotation of the first lead screw 74 causes the first slider 73 to slide along the first slide groove 75, thereby moving the first positioning block 72. The first positioning block 72 gradually inserts into the first positioning groove 71 inside the mating block 6 until it is fully embedded, achieving a firm lock between the base 3 and the mounting frame 4, enhancing the stability of the connection. After the first positioning mechanism 7 completes the connection, the first torsion block 78... Rotate to the maximum position, rotate the second torsion block 87, drive the second lead screw 85 to rotate in the second slide groove 82, and slide the second slider 83 in the second slide groove 82, pushing the second positioning block 84 to move towards the second positioning groove 86 on one side of the disc 11. When the second positioning block 84 is inserted into the second positioning groove 86, it limits and locks the first positioning mechanism 7 to prevent the first torsion block 78 from rotating accidentally and causing the first positioning mechanism 7 to loosen. When the second positioning block 84 is inserted into the second positioning groove 86, one side of it contacts the touch switch 9 inside the second positioning groove 86 and triggers the switch. After the touch switch 9 is triggered, it sends an electrical signal to the warning light 10, causing the warning light 10 to light up, indicating to the operator that the second positioning mechanism 8 has been installed stably, thereby ensuring that the first positioning mechanism 7 is installed stably. At this time, the solenoid valve can be safely put into operation, effectively resisting the periodic impact force generated by the internal fluid pressure fluctuation during the operation of the solenoid valve, as well as the influence of the external vibration environment, ensuring the stable operation of the solenoid valve.
