In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.
[0030] The present embodiment provides a novel integrated valve system, which comprises a valve seat 100 and a valve mechanism 200. The valve seat 100 of the integrated valve system is provided with two impregnation oil paths 110 and two valve mechanisms 200, and the valve mechanism 200 corresponds to the impregnation oil path 110 one by one, so that the electrolyte of the two impregnation tanks can be accurately controlled, the occupied space of the equipment is reduced, and the compactness and integration of the equipment are improved.
[0031] As shown in FIG. 1, the integrated valve system comprises a valve seat 100 and a valve mechanism 200. The valve seat 100 is provided with two impregnation oil paths 110 and two valve mechanisms 200, and the valve mechanism 200 corresponds to the impregnation oil path 110 one by one. The integrated valve system is used for controlling the electrolyte of the two impregnation tanks, and the valve seat 100 is provided with two impregnation oil paths 110 and two valve mechanisms 200, so that the electrolyte of the two impregnation tanks can be accurately controlled, the occupied space of the equipment is reduced, and the compactness and integration of the equipment are improved. Figures 1 to 4As shown, the valve seat 100 is provided with two impregnation oil paths 110 in parallel, which are used to communicate with corresponding impregnation cylinders. The bottom of one impregnation oil path 110 is provided with a pressurizing hole 111, a liquid inlet hole 112, a pressure relief hole 113 and a backflow hole 114. The valve seat 100 is further provided with a backflow pipeline 120, a liquid inlet pipeline 130, a pressure pipeline 140 and a pressurizing pipeline 150. The backflow pipeline 120 communicates with the backflow hole 114 and the pressure relief hole 113. The liquid inlet pipeline 130 communicates with the liquid inlet hole 112. The pressure pipeline 140 communicates with the pressurizing hole 111. The pressurizing pipeline 150 communicates with the pressure pipeline 140. The pressurizing pipeline 150 is connected with an opening of the liquid inlet pipeline 130.
[0032] The two impregnation oil paths 110 extend along a first direction. The opening of the impregnation oil path 110 is located on the right side of the valve seat 100. It can be understood that the first direction corresponds to the X axis of the spatial coordinate axis (i.e. the left-right direction), the second direction corresponds to the Y axis of the spatial coordinate axis (i.e. the front-back direction), and the third direction corresponds to the Z axis of the spatial coordinate axis (i.e. the up-down direction).
[0033] The backflow pipeline 120 has a total backflow interface 121 and a vacuum tank recovery port 122. The total backflow interface 121 is located on the rear side of the valve seat 100 and is used to communicate with a liquid storage barrel and make the electrolyte flow out of the valve seat 100. The vacuum tank recovery port 122 is located on the left side of the valve seat 100 and is used to communicate with a vacuum tank, so that the waste liquid in the vacuum tank can enter the backflow pipeline 120 and be discharged from the total backflow interface 121.
[0034] The liquid inlet pipeline 130 has a total liquid inlet interface 131 and a pressurizing pump inlet 132. The total liquid inlet interface 131 is located on the rear side of the valve seat 100 and is used to make the electrolyte flow into the valve seat 100. The pressurizing pump inlet 132 is located on the front side of the valve seat 100 and is used to make the electrolyte flow into the pressurizing pump.
[0035] The pressurizing pipeline 150 has a pressurizing pump outlet 151. The pressurizing pump outlet 151 is located on the front side of the valve seat 100 and is used to receive the electrolyte after being pressurized.
[0036] The pressure pipeline 140 has a total pressure interface 141. The total pressure interface 141 is located on the rear side of the valve seat 100.
[0037] It is worth noting that the valve seat 100 can be divided into an upper layer and a lower layer. The two impregnation oil paths 110 and the pressurizing pipeline 150 are located in the upper layer, and the backflow pipeline 120, the liquid inlet pipeline 130 and the pressure pipeline 140 are located in the lower layer.
[0038] Two valve mechanisms 200 are respectively arranged on the valve seat 100 and correspond to the impregnation oil path 110 one by one; the valve mechanism 200 comprises: a pressurizing valve 210, a liquid inlet valve 220, a pressure relief valve 230 and a backflow valve 240 which are sequentially and spacedly arranged on the valve seat 100, the pressurizing valve 210 is used for controlling the opening and closing of the pressurizing hole 111, the liquid inlet valve 220 is used for controlling the opening and closing of the liquid inlet hole 112, the pressure relief valve 230 is used for controlling the opening and closing of the pressure relief hole 113, and the backflow valve 240 is used for controlling the opening and closing of the backflow hole 114.
[0039] In actual application, the working processes of the two valve mechanisms 200 are the same, when one of the valve mechanisms 200 works, the other valve mechanism 200 does not work. The main working steps of the valve mechanism 200 include vacuumizing and liquid inlet, pressurizing, pressure maintaining and pressure relief and backflow.
[0040] In the initial stage, the pressurizing valve 210, the liquid inlet valve 220, the pressure relief valve 230 and the backflow valve 240 are closed.
[0041] When the impregnation cylinder needs to flow into electrolyte, the impregnation cylinder is vacuumized, the liquid inlet valve 220 is opened to open the liquid inlet hole 112, the electrolyte sequentially passes through the total liquid inlet interface 131, the liquid inlet pipeline 130, the liquid inlet hole 112, the impregnation oil path 110 and finally enters the impregnation cylinder, and the liquid inlet of the impregnation cylinder is completed.
[0042] When the impregnation cylinder needs to be pressurized, the pressurizing valve 210 is opened to open the pressurizing hole 111, the pressurizing pump starts to work, the electrolyte sequentially passes through the total liquid inlet interface 131, the liquid inlet pipeline 130, the pressurizing pump inlet 132, the pressurizing pump, the pressurizing pump outlet 151, the pressurizing pipeline 150, the pressure pipeline 140, the pressurizing hole 111, the impregnation oil path 110 and finally enters the impregnation cylinder, when the specified pressure is reached, the pressurizing valve 210 is closed to close the pressurizing hole 111, the pressurizing pump stops working, and the pressurizing of the impregnation cylinder is completed.
[0043] When the pressure in the impregnation cylinder is maintained for a period of time, the pressure relief valve 230 and the backflow valve 240 are opened, because the pressure relief valve 230 is opened first and then the backflow valve 240 is opened under the action of pressure, the electrolyte in the impregnation cylinder sequentially passes through the impregnation oil path 110, the pressure relief hole 113 and / or the backflow hole 114, the backflow pipeline 120, the total backflow interface 121 and finally enters the liquid storage barrel, when the liquid level in the impregnation cylinder drops to the specified position, the pressure relief valve 230 and the backflow valve 240 are closed, and the electrolyte stops backflowing.
[0044] As Figures 1 to 4As shown, in some embodiments, a refill pipe 160 is provided on the valve seat 100. The refill pipe 160 has a barrel refill port 161 and a refill hole 162. The barrel refill port 161 is located on the rear side of the valve seat 100, and the refill hole 162 is located at the bottom of the refill pipe 160 and communicates with the return pipe 120. The refill pipe 160 is located on the upper layer of the valve seat 100.
[0045] A barrel replenishing liquid valve 300 is provided on the valve seat 100 . The barrel replenishing liquid valve 300 is provided corresponding to the replenishing liquid hole 162 and is used to control the opening and closing of the replenishing liquid hole 162 .
[0046] In actual application, when new electrolyte is added to the liquid storage barrel, the pressure relief valve 230 closes the pressure relief hole 113, the reflux valve 240 closes the reflux hole 114, and the barrel replenishing liquid valve 300 opens the replenishing hole 162. The new electrolyte enters the replenishing pipe 160 from the barrel replenishing liquid port 161, enters the reflux pipe 120 through the replenishing hole 162, and finally enters the liquid storage barrel from the total reflux interface 121. When the liquid level in the liquid storage barrel is full, the barrel replenishing liquid valve 300 closes the replenishing hole 162.
[0047] like Figures 1 to 4 As shown, in some embodiments, a recovery pipe 170 is provided on the valve seat 100. The recovery pipe 170 has a spin-drying recovery port 171 and a recovery hole 172. The spin-drying recovery port 171 is located on the left side of the valve seat 100, and the recovery hole 172 is located at the bottom of the recovery pipe 170 and communicates with the return pipe 120. The recovery pipe 170 is located on the upper layer of the valve seat 100.
[0048] A spin-drying recovery valve 400 is provided on the valve seat 100 . The spin-drying recovery valve 400 is provided corresponding to the recovery hole 172 and is used to control the opening and closing of the recovery hole 172 .
[0049] When the electrolyte in the spin-drying barrel is recovered, the pressure relief valve 230 closes the pressure relief hole 113, the reflux valve 240 closes the reflux hole 114, and the recovery valve controls the recovery hole 172 to open. The electrolyte flows from the spin-drying barrel through the spin-drying recovery port 171 into the recovery pipe 170, and enters the reflux pipe 120 through the recovery hole 172, and finally enters the liquid storage barrel through the total reflux interface 121.
[0050] When the electrolyte of the vacuum valve is recovered, the bottom valve of the vacuum tank is opened, and the electrolyte enters the reflux pipe 120 from the vacuum tank recovery port 122, and then enters the liquid storage barrel through the total reflux interface 121.
