[0002] In the LED industry, wet cleaning refers to the process of using various chemical reagents to react or dissolve impurities and oil stains adsorbed on the surface of the wafer to be cleaned, or accompanied by physical measures such as ultrasound, heating, and vacuuming, so that impurities are desorbed (desorbed) from the surface of the object to be removed, and then rinsed with a large amount of high-purity deionized water to obtain a clean surface.

[0003] During the cleaning process, the film source stained with chemicals needs to be placed in a water tank for repeated cleaning. During the initial cleaning process, a higher concentration of wastewater will be produced because it has just been taken out of the chemical tank, while the subsequent cleaning will produce lower concentration wastewater. In the prior art, these two concentrations of wastewater are discharged together for mixed treatment, and the mixed wastewater produces higher treatment waste than the high-concentration wastewater and low-concentration wastewater discharged separately.

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] In order to solve the problem of high treatment cost caused by mixed discharge of wastewater in the prior art, the utility model provides a dual-output valve, which is provided with two cylinder valves on the valve body, and active valve poles and passive valve poles are respectively provided at both ends of the valve stem of the cylinder, the active valve pole is located in the cylinder, and the passive valve pole is arranged in the valve body, and two air holes located on both sides of the active valve pole are provided on the cylinder, and one of the two air holes of the cylinder is also connected with one of the two air holes in the other cylinder through a connecting pipe, so that when one cylinder is connected to the driving air source and actuated, the other cylinder can be driven to actuate synchronously, avoiding the two cylinders being in the open or closed state at the same time due to misoperation, and can effectively realize the selective regulation of the destination of the input liquid, and can realize the diversion of high-concentration wastewater and low-concentration wastewater of the same source, and can avoid the two output ports being opened at the same time, thereby ensuring the accuracy of the diversion, and thus maintaining the reliability of the wastewater diversion and separate treatment.

[0023] Specifically, Figure 1 and Figure 2As shown in the figure, the dual-output valve of this embodiment includes a valve body and two cylinders arranged on the valve body. The valve body is provided with an input port and two output ports arranged radially along the valve body. The two cylinders are arranged at intervals along the radial direction of the valve body and correspond to the two output ports one by one. Both ends of the valve stem of the cylinder are respectively provided with an active valve pole and a passive valve pole. The active valve pole is located in the cylinder, and the passive valve pole is arranged in the valve body. When the active valve pole moves with the change of air pressure in the cylinder, the passive valve pole can be driven to move synchronously through the valve stem, so as to control the closing state of the passive valve pole on the output port. By regulating the driving states of the two cylinders, the opening and closing of the two output ports can be controlled, and further the output direction of the liquid input from the input port can be regulated.

[0024] Two air holes are arranged on the cylinder, which are respectively located in the spaces on the upper and lower sides of the active valve pole. One of the two air holes in the cylinder is also communicated with one of the two air holes in the other cylinder through a connecting pipe, so that the two cylinders can be associated. The states of the two cylinders can be regulated simultaneously under the drive of a single driving air source, and the interlock regulation can be realized by using the association of the two cylinders, avoiding the risk that the two output ports are opened simultaneously due to misoperation, resulting in the failure of sewage drainage.

[0025] To facilitate regulating the associated state of the two cylinders, a third air hole is also arranged in the area where the two cylinders are connected through the connecting pipe. The air pressure in the connected area can be regulated through the third air hole, ensuring the reliability of the association of the two cylinders and being used for the direct drive of the two cylinders.

[0026] As a specific example, in this embodiment, the air holes include a first air hole and a second air hole respectively located on the lower side and the upper side of the active valve pole. The upper side of the active valve pole is the side away from the passive valve pole. The second air holes of the two cylinders are communicated through a connecting pipe. The first air hole is used to communicate with the driving air source. When high-pressure gas is introduced into one of the two first air holes and the other is left empty or connected to a low-pressure air source, one active valve pole can be pushed upward, and then through the transmission of the connected part, the other active valve pole can be pushed downward, so that one output port can be opened and the other output port can be closed. By changing the direction of the high-pressure air source introduced, the open position of the output port can be changed, ensuring that only one output port is open at the same time.

[0027] In this embodiment, as Figure 2 shown, the third air hole can be arranged at the top of the two cylinders. A gas valve can be arranged at the position of the third air hole to adjust the air pressure in the closed part, or connect other air pumps to inflate and pressurize it. And the two output ports can be closed simultaneously by separately pressurizing the connected area of the two cylinders, realizing the complete closing of the dual-output control valve.

[0028] In an alternative embodiment, the first air holes of the two cylinders are communicated through a connecting pipe, and the second air holes are used to communicate with the driving air source, which can achieve the same function.

[0029] When the first air hole and the second air hole are arranged on the side wall of the cylinder, to ensure the reliable operation of the cylinder, when the active valve pole runs to the upper and lower limit positions, a certain space should be reserved in the cylinder for the arrangement of the first air hole and the second air hole. For example, in this embodiment, a blocking step is arranged below the inside of the cylinder, the first air hole is arranged in the area below the blocking step, and the active valve pole stops when it moves down to the blocking step, ensuring that the first air hole only communicates with the lower side space of the active valve pole, and the upper limit position can be controlled by the valve rod and the passive valve pole. Among them, when the second air hole and the connecting pipe are arranged on the top of the cylinder, the size requirement for the reserved space can be reduced, and the actual arrangement positions of the air holes can be specifically selected according to specific needs.

[0030] In the above two embodiments, the two cylinders are associated through the middle air chamber, and the air chamber belongs to flexible transmission. Each time the switching state of the valve is changed, the actions of the two active valve poles will have a certain delay due to the existence of the air chamber, resulting in the problem that when changing the switching configuration of the two output ports of the double-output valve, there will be a problem that the two output ports are simultaneously in the open state for a long period of time during the conversion period.

[0031] In an alternative embodiment, the first air hole of one of the two cylinders is communicated with the second air hole of the other of the two cylinders through a connecting pipe, and the air holes in the non-connected area can be selectively opened, and the connected area is connected to the air source through a third air hole. During use, when one of the output ports is closed and there is liquid transportation in the pipeline, under the influence of the liquid output pressure, it is difficult to retract its valve pole. At this time, a high-pressure air source is sent into the connected area, then the other output port will be preferentially closed, thereby avoiding the problem of the two output ports being simultaneously opened and ensuring the accuracy of waste liquid diversion.

[0032] It should be noted that when used to select the output direction of waste liquid with different concentrations, when switching the output port, generally, it is necessary to ensure that the input stops and the waste liquid is emptied without residue, and then the output port is switched. In this way, there is no need to consider the problem of discharge mixing caused by the two output ports being simultaneously opened, or the problem of waste liquid residue being remixed due to the two being simultaneously closed. When it is necessary to switch the output port during discharge in real time, one of the above embodiments can be selected according to specific requirements.

[0033] To ensure the sealing effect, in this embodiment, a sealing ring is also arranged on the end face of the passive valve pole facing the output port. When the passive valve pole is pressed tightly against the inner end face of the output port, the sealing ring is synchronously pressed tightly around the output port, thereby ensuring its sealing reliability. Among them, multiple sealing rings can also be concentrically arranged to further improve the sealing effect. The lower limit position of the active valve pole is realized by the blocking step in the cylinder, which can also prevent the sealing ring from being overly squeezed, ensuring the structural reliability of the sealing ring and further ensuring the sealing reliability.

[0034] As a preferred choice, the sealing ring includes a perfluororubber ring, which has good thermal stability and chemical stability. In addition to swelling in fluorinated solvents, it is stable to all chemicals and can maintain its sealing performance in the cleaning waste liquid of the wafer.
