Description

Technical Field

[0001] This application relates to the field of solenoid valves, and in particular to a multi-unit solenoid valve manifold. Background Technology

[0002] A solenoid valve manifold is a pneumatic component that distributes a single air source to multiple solenoid valves, enabling centralized air supply and exhaust while saving space. It has at least two through-channels: an inlet and an outlet. After distribution, the air source is connected to components requiring air, such as solenoid valves, via pneumatic hoses and other accessories, allowing a small amount of air to simultaneously supply multiple pneumatic components. Manifolds are mostly made of 6061-T651 aluminum alloy, which has excellent corrosion resistance and toughness, making it a key component for gas distribution and control in pneumatic automation systems.

[0003] For example, the detachable solenoid valve manifold with patent number CN210859389U has the following shortcomings in actual use:

[0004] The above-mentioned device achieves the loading and unloading of the solenoid valve manifold by selecting different intermediate modules to form the required manifold, which reduces the production cycle, improves product adaptability, and facilitates large-scale production. Furthermore, matching protrusions and recesses are set on the front module, intermediate module, and rear module to improve positioning accuracy. However, the production process of the solenoid valve manifold requires the production of multiple parts, and the structure is complex, making production difficult and inefficient. Summary of the Invention

[0005] In order to improve the technical problem of complex structure and difficulty in production of solenoid valve manifold, this application provides a multi-unit solenoid valve manifold device.

[0006] The multi-connected solenoid valve manifold device provided in this application adopts the following technical solution:

[0007] A multi-unit solenoid valve manifold includes a plate. A main air hole is provided in the middle of the plate, and connectors are connected to both ends of the main air hole for connecting the air supply path. Several air inlets of the same height and evenly spaced are provided on the rear side of the plate, and the air inlets are connected to the main air hole. Several exhaust holes penetrating the plate are provided on the plate, and the exhaust holes are located directly below the air inlets. Several output holes are provided at the bottom of the plate, and output pipes are connected to the output holes. Several air outlet holes of the same height and evenly spaced are provided on the rear side of the plate, and the air outlet holes are connected to the output holes.

[0008] By adopting the above technical solution, an air inlet, an air outlet, and an air outlet are opened on the rear side of the plate, and an output hole is opened at the bottom of the plate. All of them are unidirectional openings, which are simple to produce. When in use, the main air hole is connected to the air supply circuit. Compressed gas enters the solenoid valve from the air inlet. When the solenoid valve is closed, the gas no longer flows. When the solenoid valve is open, the gas will enter the air outlet through the outlet of the solenoid valve and finally be supplied to the pneumatic device through the output hole.

[0009] Preferably, the rear side of the plate is provided with a plurality of mounting plates, each mounting plate having three through holes aligned with an air inlet, an air outlet, and an air outlet, and two mounting holes, and a quick-connect mechanism is provided between the mounting plate and the plate.

[0010] By adopting the above technical solution, during installation, the mounting plate is first connected to the solenoid valve through bolts and mounting holes, and then the mounting plate is connected to the plate body through the quick-connect mechanism. The steps of assembling and disassembling the solenoid valve are simple, and it is easy to repair in case of air circuit failure.

[0011] Preferably, both sides of the mounting plate are provided with embedding grooves surrounding the through hole, and a sealing gasket is embedded in the embedding groove.

[0012] By adopting the above technical solution, the sealing gasket can improve the airtightness between the mounting plate and the plate body, as well as the solenoid valve, and prevent gas leakage.

[0013] Preferably, the quick-connect mechanism includes an insert fixed to the lower end of the mounting plate, and a slotted part matching the insert is fixed to the bottom rear side of the plate. An elastic latch is fixed to the upper end of the mounting plate, and a slot matching the elastic latch is opened on the rear side of the plate.

[0014] By adopting the above technical solution, when installing the mounting plate, insert the bottom insert into the inside of the slot, and then push the upper end of the mounting plate towards the plate body. The elastic latch will be fixed by the slot, thus quickly fixing the mounting plate. Similarly, when disassembling, simply pull the upper end of the mounting plate outward to separate the elastic latch from the slot.

[0015] Preferably, a deformation cavity is formed on the inner side of the elastic latch.

[0016] By adopting the above technical solution, the deformation cavity can improve the deformation capacity of the elastic latch, provide deformation space, and prevent the elastic latch from breaking.

[0017] Preferably, a plurality of lifting grooves aligned with the air inlet are provided above the main air hole, a lifting block is slidably arranged in the lifting groove, a vent hole is provided in the middle of the lifting block, a threaded hole is provided at the top of the lifting groove, a threaded rod is threadedly connected in the threaded hole, the bottom of the threaded rod is rotatably connected to the lifting block, and a knob is fixed at the upper end of the threaded rod.

[0018] By adopting the above technical solution, tightening the threaded rod can drive the lifting block to descend, thereby blocking the air inlet. This allows unused air inlets to be closed for convenient use.

[0019] Preferably, a sealing ring is fitted on the outer side of the lifting block.

[0020] By adopting the above technical solution, the sealing ring can improve the sealing effect of the lifting block on the air inlet and prevent air leakage.

[0021] Preferably, the inner side of the plate has a cavity communicating with the slot, a disc is fixed on the threaded rod, the disc is located inside the cavity, and a limiting ring is provided on the edge of the disc. A limiting block is fixed at the bottom of the elastic latch, and a limiting groove is provided on the limiting block. One side of the limiting ring is located in the limiting groove.

[0022] By adopting the above technical solution, before disassembling the solenoid valve, the threaded rod needs to be tightened to drive the limit ring downwards out of the limit groove, and then the mounting plate can be disassembled smoothly. This prevents the disassembly of one solenoid valve from affecting other solenoid valves, and it is not necessary to stop the use of other solenoid valves when disassembling and installing the solenoid valve.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. It is connected to a solenoid valve through an air inlet, an air outlet, and an air outlet. The gas supply to the pneumatic device can be controlled by opening and closing the solenoid valve. The air path distribution is simple and the assembly is convenient. Moreover, the plate is an integral structure with an air inlet, an air outlet, and an air outlet on the rear side of the plate and an output hole on the bottom of the plate. All of them are unidirectional openings, making the manufacturing process relatively simple. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses a multi-connected solenoid valve manifold device.

[0034] Reference Figure 1 , Figure 2 and Figure 4 A multi-unit solenoid valve manifold includes a plate 1. A main air port 2 is located in the middle of the plate 1, and connectors 3 are installed at both ends of the main air port 2 for connecting to the air supply circuit. Several air inlets 4 of the same height are evenly distributed on the rear side of the plate 1, and these air inlets 4 are connected to the main air port 2. Simultaneously, several exhaust ports 5 penetrating the plate 1 are provided, with the exhaust ports 5 located directly below the air inlets 4. Several output ports 6 are opened at the bottom of the plate 1, and each output port 6 is connected to an output pipe 7. Furthermore, several air outlet ports 25 of the same height are evenly distributed on the rear side of the plate 1, and the air outlet ports 25 are connected to the output ports 6.

[0035] With the above setup, after installing the solenoid valve 27, the air inlet 4, air outlet 5, and air outlet 25 are aligned with the air inlet, air outlet, and working port of the solenoid valve 27, respectively. In use, the main air port 2 is connected to the air supply circuit. Compressed gas enters the solenoid valve 27 through the air inlet 4. When the solenoid valve 27 is closed, the gas stops flowing. When the solenoid valve 27 is open, the gas enters the air outlet 25 through the outlet of the solenoid valve 27 and is finally supplied to the pneumatic device through the output port 6. Different actuators can be controlled separately using a single air source. The structure is simple and facilitates equipment control.

[0036] Reference Figure 3 and Figure 4On the rear side of the plate body 1, several mounting plates 8 are installed. Each mounting plate 8 has three through holes 10, which are respectively aligned with the air inlet 4, exhaust 5, and air outlet 25 on the plate body 1. Both sides of the mounting plate 8 have embedding grooves surrounding the through holes 10, and sealing gaskets 11 are embedded in the embedding grooves to ensure the sealing of the connection. In addition, the mounting plate 8 also has two mounting holes 9 for fixing the mounting plate 8 to the solenoid valve 27.

[0037] The mounting plate 8 and the plate body 1 are connected by a quick-connect mechanism. This quick-connect mechanism includes an insert 12 fixed to the lower end of the mounting plate 8 and a slotted piece 14 fixed to the bottom rear side of the plate body 1 and matching the insert 12. Initial positioning is achieved through the cooperation of the insert 12 and the slotted piece 14. Simultaneously, an elastic latch 13 is fixed to the upper end of the mounting plate 8, and a slot 15 matching the elastic latch 13 is provided on the rear side of the plate body 1. A secure connection is achieved by the elastic latch 13 engaging with the slot 15. Furthermore, a deformation cavity 26 is provided on the inner side of the elastic latch 13, providing space for deformation of the elastic latch 13, facilitating installation and disassembly.

[0038] With the above setup, during installation, first use bolts to pass through the mounting holes 9 on the mounting plate 8 and connect it to the solenoid valve 27. Next, align the insert 12 at the bottom of the mounting plate 8 and insert it into the groove 14 at the bottom rear side of the plate body 1 to complete the initial positioning. Then, simply push the upper end of the mounting plate 8 gently towards the plate body 1, and the elastic latch 13 at the upper end of the mounting plate 8 will deform elastically under force and smoothly engage in the corresponding groove 15 on the rear side of the plate body 1, thereby achieving rapid fixation of the mounting plate 8 and the plate body 1. During this process, the sealing gasket 11 embedded in the mounting plate 8 can fit tightly, effectively improving the airtightness between the mounting plate 8, the plate body 1, and the solenoid valve 27, eliminating the risk of gas leakage.

[0039] Disassembly is equally simple. Simply pull the upper end of the mounting plate 8 outwards; under the pulling force, the elastic latch 13 will elastically deform again, disengaging from the slot 15 and separating the mounting plate 8 from the plate body 1. Furthermore, the deformation cavity 26 inside the elastic latch 13 provides ample deformation space, greatly enhancing its deformation capacity and effectively preventing it from breaking due to excessive force during frequent disassembly and assembly.

[0040] Reference Figure 4 and Figure 5 Above the main air vent 2, a lifting groove is provided corresponding to the position of each air inlet 4, and the lifting groove is aligned with the air inlet 4. A lifting block 16 is slidably installed in each lifting groove, and a vent hole is provided in the middle of the lifting block 16 for gas circulation. To ensure sealing, a sealing ring 19 is fitted on the outside of the lifting block 16.

[0041] The top of the lifting groove has a threaded hole, through which a threaded rod 17 is threadedly connected. The bottom of the threaded rod 17 is rotatably connected to the lifting block 16, so that when the threaded rod 17 rotates, the lifting block 16 does not rotate with it, but moves vertically up and down along the lifting groove. In addition, a knob 18 is fixedly installed at the upper end of the threaded rod 17. By rotating the knob 18, the rotation of the threaded rod 17 can be easily controlled, thereby adjusting the position of the lifting block 16 within the lifting groove.

[0042] With the above settings, tightening the threaded rod 17 will cause the lifting block 16 to descend, thereby blocking the air inlet 4. The unused air inlet 4 can be closed, and it can be used in any position without the need to install a solenoid valve 27 in every position, making the usage more flexible.

[0043] Reference Figure 4 , Figure 5 and Figure 6 Inside the plate 1, a cavity 22 is formed that communicates with the slot 15. A disc 20 is fixedly sleeved on the threaded rod 17, located inside the cavity 22, and a limiting ring 21 is provided around the edge of the disc 20. At the same time, a limiting block 23 is fixedly connected to the bottom of the elastic latch 13. A limiting groove 24 is formed on the limiting block 23, and one side of the limiting ring 21 is precisely embedded in the limiting groove 24. This structure further constrains and stabilizes the movement trajectory of the elastic latch 13.

[0044] With the above setup, the threaded rod 17 must be tightened before disassembling the solenoid valve 27. As the threaded rod 17 rotates, the fixed limiting ring 21 will move downwards until it disengages from the limiting groove 24 on the bottom limiting block 23 of the elastic latch 13. After completing this step, the mounting plate 8 can be easily removed. This design ensures that the main air port 2 will not leak air when disassembling one of the solenoid valves 27, and will not interfere with the normal operation of other solenoid valves 27. Moreover, during the disassembly and installation of the solenoid valve 27, it is not necessary to pause the operation of other solenoid valves 27, thus achieving independent operation of each solenoid valve 27.

[0045] The implementation principle of a multi-connected solenoid valve manifold device according to an embodiment of this application is as follows:

[0046] After installing the solenoid valve 27, the air inlet 4, air outlet 5, and air outlet 25 are aligned with the air inlet, air outlet, and working port of the solenoid valve 27, respectively. In use, the main air port 2 is connected to the air supply circuit. Compressed gas enters the solenoid valve 27 from the air inlet 4. When the solenoid valve 27 is closed, the gas no longer flows. When the solenoid valve 27 is open, the gas will enter the air outlet 25 through the outlet of the solenoid valve 27 and finally be supplied to the pneumatic device through the output port 6. Different actuators can be controlled separately by one air source. The structure is simple and convenient for controlling the equipment. The solenoid valve 27 is equipped with a mounting plate 8, which can be quickly disassembled and assembled with the plate body 1 through the elastic latch 13 and the insert 12. This allows for quick disassembly and assembly of the solenoid valve 27. Before disassembling the solenoid valve 27, the threaded rod 17 must be tightened to close the air inlet 4 and disengage the limiting ring 21 from the limiting groove 24, enabling independent operation of each solenoid valve 27. In addition, tightening the threaded rod 17 can block the air inlet 4, closing the unused air inlet 4. It can be used in any position without the need to install a solenoid valve 27 in every position, making the usage more flexible.

[0047] In summary, this device can control different actuators separately using a single air source. It has a simple structure, facilitates equipment control, and is easy to manufacture.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
