[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] Reference Figure 1-2 As shown, an embodiment of the utility model is as follows: a high-low concentration discharge valve comprises a valve body 1, a liquid inlet hole 2 is arranged downwardly at the center of the upper surface of the valve body 1, and the solution flows into the valve body 1 from the liquid inlet, and two liquid outlet holes 3 are arranged upwardly at the lower surface of the valve body 1, and the two liquid outlet holes 3 are symmetrical relative to the center of the valve body 1, and solutions of different concentrations flow out of the two liquid outlet holes 3, and a liquid inlet pipe 4 is arranged at the center of the valve body 1, and the liquid inlet pipe 4 is connected with the liquid inlet hole 2, and liquid outlet pipes 5 are symmetrically arranged on the left and right sides of the liquid inlet pipe 4, and the two liquid outlet pipes 5 are respectively connected to the corresponding two liquid outlet holes 3 through liquid outlets 9 A sliding device 6 is provided between the liquid inlet pipe 4 and the two liquid outlet pipes 5, which can move left and right and respectively close the two liquid outlet pipes 5; pneumatic structures 7 are respectively provided on the left and right sides of the valve body 1, and air inlet holes 8 are provided on the front sides of the two pneumatic structures 7. The sliding device 6 includes a moving rod 61, and both ends of the moving rod 61 are threadedly connected to sealing plates 62. The two sealing plates 62 are respectively arranged in the two liquid outlet pipes 5, and air is inflated from the air inlet holes 8 to increase the internal pressure of the pneumatic structure 7 and move it to the left or right, so that the sealing plate 62 is closely fitted with the liquid inlet pipe 4 to achieve sealing.
[0016] Furthermore, the sealing plate 62 includes an outer circular surface 63 and an inner circular surface 64, and a groove 65 is arranged between the outer circular surface 63 and the inner circular surface 64. The diameter of the outer circular surface 63 is adapted to the diameter of the liquid outlet pipe 5, and the diameter of the inner circular surface 64 is larger than the diameter of the liquid inlet pipe 4. The groove 65 can help to discharge the gas at the sealing point, while also reducing the area of the inner circular surface 64 and the contact area between the inner circular surface 64 and the side of the liquid inlet pipe 4, thereby reducing the friction and improving the sealing performance of the sealing plate 62.
[0017] Furthermore, a pneumatic rod 71 is slidably arranged in the pneumatic structure 7, and the inner end of the pneumatic rod 71 is clamped with the sealing plate 62. A sealing plug 72 is arranged at the other end of the pneumatic rod 71. The sealing plug 72 seals the pneumatic structure 7 to prevent the internal air pressure from being unstable when air is inflated inward through the air inlet, and the moving distance of the sealing plate 62 and the pressure between the sealing plate 62 and the side of the liquid inlet pipe 4 cannot be well controlled, thereby increasing the friction force and reducing the sealing effect, which may cause leakage of the solution.
[0018] Furthermore, the distance between the two sealing plates 62 is greater than the shortest distance between the side walls of the two liquid outlets 9, and the thickness of the sealing plate 62 is less than the diameter of the liquid outlet 9, so as to prevent the sealing plate 62 from moving, causing the solution to be unable to flow through the liquid inlet pipe 4 to the liquid outlet pipe 5 and flow out of the liquid outlet hole 3 due to the short movable distance or the thick thickness of the sealing plate 62, thereby making it impossible to control high-concentration and low-concentration solutions.
[0019] Working principle: When the staff uses the cleaning tank for cleaning, they select cleaning solutions of different concentrations according to different cleaning requirements. The two liquid outlets 9 flow out high-concentration and low-concentration solutions respectively. First, the left air inlet 8 is inflated to increase the internal pressure of the pneumatic structure 7 on the left, so that the sealing plate 62 and the moving rod 61 move to the right. When the inner circular surface 64 contacts the left side of the liquid inlet pipe 4, the liquid outlet 3 on the left is sealed, and the high-concentration solution can only flow out from the right liquid outlet pipe 5. When a low-concentration solution needs to be added, the right air inlet 8 is inflated, the sealing plate 62 and the moving rod 61 move to the left, and the sealing plate 62 seals the liquid outlet 3 on the right side, and the low-concentration solution can only flow out from the left liquid outlet pipe 5.
[0020] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
