Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1-5 This utility model provides the following two technical solutions:

[0027] First technical solution: A diaphragm valve electrolytic polishing device, comprising a housing 1, wherein the housing 1 is connected to a polishing assembly for electrolytic polishing of the diaphragm valve, the polishing assembly comprising:

A return pipe 28 connected to a set of liquid storage shells 26 is provided at the lower end of the first solenoid valve 27. A first cathode plate 29 is installed in both sets of liquid storage shells 26.

[0029] Processing component 3, installed inside housing 1, is used for electrolyte reflux and anode power supply processing. Processing component 3 includes a first cylinder 34 installed on the upper side inside housing 1, with an anode block 35 at the bottom of the first cylinder 34; a receiving component 4, installed at the bottom middle of housing 1 for receiving the diaphragm valve; a second cathode plate 5, installed on the lower right side inside housing 1; the polishing assembly also includes connecting pipes fixedly connected to the right sides of two sets of liquid storage tanks 26 respectively; a cabinet door 7 is provided on the upper left side of housing 1; a bidirectional screw 22 is coaxially fixedly connected to the output end of motor 21, motor 21 is a servo motor; and two sets of movable frames 23. The positioning seats 24 are all electrically connected to the external anode power supply terminal. Both sets of positioning seats 24 are provided with several positioning rods near the middle of the housing 1. The middle of the positioning seat 24 is provided with a connecting groove. The liquid supply component 25 includes a liquid pump 251 installed on the outside of the housing 1. The liquid pump 251 has a liquid pumping pipe 252 installed at the liquid pumping end, which is fixedly connected and connected to a set of liquid storage shells 26. The liquid pump 251 has a three-way valve 253 installed at the liquid discharge end. A first conduit 254 fixedly connected to a set of positioning seats 24 is installed on the rear side of the three-way valve 253. A branch pipe 255 fixedly connected and connected to the housing 1 is installed on the upper side of the three-way valve 253.

[0030] The processing component 3 also includes a second conduit 31 fixedly connected to another set of positioning seats 24. A second solenoid valve 32 fixedly connected to the second conduit 31 is provided on the rear side of the housing 1. A connecting pipe 33 fixedly connected and communicating with another set of liquid storage shells 26 is provided on the rear side of the second solenoid valve 32. Both the first conduit 254 and the second conduit 31 are corrugated pipes. The front and rear sides of the diaphragm valve are positioned and connected by the motor 21, the bidirectional screw 22, the two sets of movable frames 23, and the positioning seats 24, so that the liquid pump 251, the liquid extraction pipe 252, the three-way valve 253, the first conduit 254, the branch pipe 255, the liquid storage shell 26, the first cathode plate 29, the second conduit 31, the second solenoid valve 32, the connecting pipe 33, the first cylinder 34, the anode block 35, and the second cathode plate 5 cooperate with each other and are adjusted according to the polishing position of the diaphragm valve to improve polishing efficiency.

[0031] The main difference between the second technical solution and the first technical solution is:

The top of the second cylinder 41 is provided with a receiving block 42 for receiving the diaphragm valve near the inner side of the housing 1. The upper side of the receiving block 42 is provided with a receiving groove for storing the diaphragm valve. The lower side of the receiving block 42 is fixedly connected to the extension end of the second cylinder 41 and is fixedly connected to the lower side of the housing 1. The receiving block 42 receives the diaphragm valve through the receiving groove, which facilitates the docking of the two sets of positioning seats 24 with the front and rear sides of the diaphragm valve. When it is necessary to electrolytically polish the outer side of the diaphragm valve, the second cylinder 41 drives the receiving block 42 to separate from the diaphragm valve. At this time, the diaphragm valve is only positioned and clamped by the two sets of positioning seats 24, thereby increasing the contact area between the outer surface of the diaphragm valve and the electrolyte. The telescopic tube 43 plays a protective role for the extension end of the second cylinder 41.

[0033] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0034] When in use, the user opens the cabinet door 7, places the diaphragm valve to be stored into the receiving groove in the receiving block 42, starts the motor 21, and the motor 21 drives the bidirectional screw 22 to rotate. The rotation of the bidirectional screw 22 drives the two sets of movable frames 23 and positioning seats 24 to move towards the front and rear sides of the diaphragm valve. After the two sets of positioning seats 24 are engaged with the connecting ends of the front and rear sides of the diaphragm valve, the motor 21 is turned off. When it is necessary to polish the inside of the diaphragm valve, the first cylinder 34 drives the first anode block 35 to move down, so that the bottom of the first anode block 35 fits against the upper end of the diaphragm valve.

[0035] Power is supplied to the first anode block 35 and the first cathode plate 29, and the liquid pump 251 is started. The liquid pump 251 draws electrolyte from the storage tank 26 through the liquid extraction pipe 252. Then, the electrode liquid is injected into the diaphragm valve through the three-way valve 253, the first conduit 254, and a set of positioning seats 24. Then, the electrolyte flows into another set of storage tanks 26 through another set of positioning seats 24 and the second conduit 31. The first cathode plate 29 in the two sets of storage tanks 26 cooperates with the electrode liquid and the anode block 35 to electrolytically polish the inside of the diaphragm valve. The diaphragm needs to be cleaned. When the valve is electrolytically polished, the anode block 35 and the receiving block 42 are separated from the diaphragm valve by the first cylinder 34 and the second cylinder 41, respectively. At this time, the two sets of positioning seats 24 lock the diaphragm valve, close the second solenoid valve 32 and switch the three-way valve 253. At this time, the electrolyte is injected into the lower side of the housing 1 through the branch pipe 255. After the electrolyte has submerged the upper end of the diaphragm valve, the three-way valve 253 is reset to supply anode power to the movable frame 23 and the positioning seat 24, and cathode power to the second cathode plate 5, thereby polishing the outer surface of the diaphragm valve.
