The operator needs to screw multiple hexagonal screws, which is cumbersome, increases the installation time, and reduces the practicality of the device. Therefore, a pneumatic double diaphragm pump flow stabilizer and pressure regulator is provided to solve the above problems. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a pneumatic double diaphragm pump flow stabilizer and pressure regulator to solve the problems raised in the above background art:

[0006] The device needs to use multiple internal hexagonal screws to fasten the flow stabilizer cover, inner clamping cover, and sealing gasket from the inside. The operator needs to screw multiple hexagonal screws, which is cumbersome, increases the installation time, and reduces the practicality of the device.

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0008] Pneumatic double diaphragm pump flow stabilizer and pressure regulator, including a medium channel. A protective block is fixedly connected to the top of the medium channel. A flow stabilizer and pressure regulator cover is arranged outside the protective block. Clamping blocks are symmetrically and fixedly connected to the top of the protective block. Sliders are symmetrically and slidably connected inside the flow stabilizer and pressure regulator cover. A clamping groove for cooperating with the clamping block is formed inside the slider. A sealing plate is slidably connected inside the flow stabilizer and pressure regulator cover. A first groove is formed inside the protective block. A diaphragm is fixedly connected inside the first groove. When the clamping block enters the inside of the clamping groove, the slider limits and fixes the clamping block under the elastic force of the second spring. Thus, the flow stabilizer and pressure regulator cover and the protective block can be quickly connected and fixed. When the liquid flowing into the outlet of the diaphragm pump has the maximum flow rate and pressure, the sealing plate is lifted upward by the diaphragm, increasing the volume of the inner cavity of the medium channel, thereby reducing the flow rate and pressure at the outlet of the pneumatic double diaphragm pump flow stabilizer and pressure regulator. When the flow rate and pressure are at the lowest, the sealing plate moves downward under the self-elastic force of the first spring, pressing the diaphragm downward and reducing the volume of the inner cavity of the medium channel.

[0009] Preferably, a threaded rod is rotatably connected inside the flow stabilizer and pressure regulator cover. A moving rod is threadedly connected to the outside of the threaded rod. A lifting plate is fixedly connected to the bottom of the moving rod. A first spring is fixedly connected to the bottom of the lifting plate. The first spring is fixedly connected to the sealing plate. The threaded rod pushes the lifting plate to move downward through the moving rod. The lifting plate pushes the sealing plate to move downward through the first spring, pressing the diaphragm towards the inner cavity of the medium channel for convenient pressure adjustment at the use site.

[0010] Preferably, a torsion block is fixedly connected to the top of the threaded rod. Limiting grooves are symmetrically formed inside the flow stabilizer and pressure regulator cover. Limiting rods are slidably connected inside the limiting grooves. The limiting rods are fixedly connected to the lifting plate. Rotating the torsion block drives the threaded rod to rotate, facilitating the limitation of the lifting plate and preventing the lifting plate from shifting during movement.

[0011] Preferably, a flange connecting pipe is fixedly connected to one end of the medium channel. An outlet pipe is fixedly connected to the other end of the medium channel. The pneumatic double diaphragm pump flow stabilizer and pressure regulator is connected to one end of the liquid outlet of the diaphragm pump through the flange connecting pipe.

[0012] Preferably, second grooves are symmetrically formed inside the flow stabilizer and pressure regulator cover. Second springs are fixedly connected inside the second grooves. The second springs are fixedly connected to the sliders. Pressing the flow stabilizer and pressure regulator cover to contact the protective block, the clamping block enters the inside of the clamping groove, and the slider limits and fixes the clamping block under the elastic force of the second spring. Thus, the flow stabilizer and pressure regulator cover and the protective block can be quickly connected and fixed, with convenient operation.

[0013] Preferably, a third groove is formed inside the slider. When it is necessary to disassemble the steady flow stabilizer cover, the user pulls the slider to move through the third groove, and then pulls the steady flow stabilizer cover to move the latch out of the clamping groove, which is convenient for disassembling the steady flow stabilizer cover.

[0014] The present utility model provides a pneumatic double diaphragm pump steady flow stabilizer. Compared with the prior art, it has the following

[0015] beneficial effects:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a pneumatic double diaphragm pump flow and pressure stabilizer, which includes a medium channel 1. A protective block 2 is fixedly connected to the top of the medium channel 1. A flow and pressure stabilizer cover 4 is arranged outside the protective block 2. Clamping blocks 21 are symmetrically and fixedly connected to the top of the protective block 2. Sliders 17 are symmetrically and slidably connected to the inside of the flow and pressure stabilizer cover 4. A clamping groove 20 for cooperating with the clamping block 21 is opened inside the slider 17. A sealing plate 14 is slidably connected to the inside of the flow and pressure stabilizer cover 4. A first groove 6 is opened inside the protective block 2. A diaphragm 7 is fixedly connected to the inside of the first groove 6. The clamping block 21 enters the inside of the clamping groove 20, and the slider 17 limits and fixes the clamping block 21 under the elastic force of the second spring 19. Thus, the flow and pressure stabilizer cover 4 and the protective block 2 can be quickly connected and fixed. When the liquid flowing into the outlet of the diaphragm pump has the maximum flow rate and pressure, the sealing plate 14 is lifted upward by the diaphragm 7, increasing the volume of the inner cavity of the medium channel 1, thereby reducing the flow rate and pressure at the outlet of the diaphragm pump flow and pressure stabilizer. When the flow rate and pressure are at the lowest, the sealing plate 14 moves downward under the self-elastic force of the first spring 10, pressing the diaphragm 7 downward, reducing the volume of the inner cavity of the medium channel 1.

[0024] Further, a threaded rod 9 is rotatably connected to the inside of the flow and pressure stabilizer cover 4. A moving rod 12 is threadedly connected to the outside of the threaded rod 9. A lifting plate 8 is fixedly connected to the bottom of the moving rod 12. A first spring 10 is fixedly connected to the bottom of the lifting plate 8. The first spring 10 is fixedly connected to the sealing plate 14. The threaded rod 9 pushes the lifting plate 8 to move downward through the moving rod 12, and the lifting plate 8 pushes the sealing plate 14 to move downward through the first spring 10, pressing the diaphragm 7 towards the inner cavity of the medium channel 1 for convenient pressure adjustment at the use site.

[0025] Further, a torsion block 11 is fixedly connected to the top of the threaded rod 9. Limiting grooves 15 are symmetrically opened inside the flow and pressure stabilizer cover 4. Limiting rods 13 are slidably connected to the inside of the limiting grooves 15. The limiting rods 13 are fixedly connected to the lifting plate 8. Rotating the torsion block 11 drives the threaded rod 9 to rotate, facilitating the limitation of the lifting plate 8 and preventing the lifting plate 8 from shifting during the moving process.

[0026] Further, a flange connection pipe 3 is fixedly connected to one end of the medium channel 1, and an outlet pipe 5 is fixedly connected to the other end of the medium channel 1. The pneumatic double diaphragm pump flow and pressure stabilizer is connected to one end of the liquid outlet of the diaphragm pump through the flange connection pipe 3.

[0027] Furthermore, second grooves 16 are symmetrically formed inside the steady flow voltage stabilizer cover 4. A second spring 19 is fixedly connected inside the second grooves 16. The second spring 19 is fixedly connected to the slider 17. When the steady flow voltage stabilizer cover 4 is pressed to contact the outer protection block 2, the clamping block 21 enters the inside of the clamping groove 20. The slider 17 limits and fixes the clamping block 21 under the elastic force of the second spring 19. Thus, the steady flow voltage stabilizer cover 4 and the outer protection block 2 can be quickly connected and fixed, and the operation is convenient.

[0028] Furthermore, a third groove 18 is formed inside the slider 17. When the steady flow voltage stabilizer cover 4 needs to be disassembled, the user pulls the slider 17 to move through the third groove 18, and pulling the steady flow voltage stabilizer cover 4 can move the clamping block 21 out of the inside of the clamping groove 20, facilitating the disassembly of the steady flow voltage stabilizer cover 4.

[0029] During operation, the pneumatic double diaphragm pump steady flow voltage stabilizer is connected to one end of the liquid outlet of the diaphragm pump through the flange pipe 3. When the steady flow voltage stabilizer cover 4 is pressed to contact the outer protection block 2, the clamping block 21 enters the inside of the clamping groove 20. The slider 17 limits and fixes the clamping block 21 under the elastic force of the second spring 19. Thus, the steady flow voltage stabilizer cover 4 and the outer protection block 2 can be quickly connected and fixed, and the operation is convenient. Rotate the torsion block 11 to drive the threaded rod 9 to rotate. The threaded rod 9 pushes the lifting plate 8 to move downward through the moving rod 12. The lifting plate 8 pushes the sealing plate 14 to move downward through the first spring 10, pressing the diaphragm 7 against the chamber inside the medium channel 1. To facilitate the pressure adjustment at the use site, when the liquid flowing into the diaphragm pump outlet has the maximum flow rate and pressure, the sealing plate 14 is lifted upward by the diaphragm 7, increasing the volume of the inner chamber of the medium channel 1, thereby reducing the flow rate and pressure at the outlet of the diaphragm pump steady flow voltage stabilizer. When the flow rate and pressure are at the lowest, the sealing plate 14 moves downward under the self-elastic force of the first spring 10, pressing the diaphragm 7 downward, reducing the volume of the inner chamber of the medium channel 1, thereby increasing the flow rate and pressure at the outlet of the diaphragm pump steady flow voltage stabilizer. Thus, the flow rate and pressure at the outlet section of the steady flow voltage stabilizer are maintained within a stable fluctuation range, ultimately achieving the function of cutting peaks and filling valleys for the liquid output of the diaphragm pump, and improving the practicability of the device.
