For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] The utility model provides an online mixing valve, which is used to be connected to a mixing pipe to mix the fluids flowing out of the mixing pipe evenly. Figure 1 and Figure 2 As shown, the online mixing valve has a first direction X, and the online mixing valve includes a valve body 1, a first plate 2 and a second plate 3. A fluid channel 11 for fluid circulation is formed inside the valve body 1, and an end of the valve body 1 is used to connect with the mixing tube to connect the fluid channel 11 with the mixing tube; the first plate 2 is installed in the fluid channel 11 and connected to the valve body 1, and a plurality of first flow holes 21 connected with the fluid channel 11 are opened on the first plate 2; the second plate 3 is installed in the fluid channel 11 and connected to the valve body 1, and a plurality of second flow holes 31 connected with the fluid channel 11 are opened on the second plate 3; the first plate 2 and the second plate 3 are arranged along the first direction X, the first flow holes 21 and the second flow holes 31 are connected to each other, and the central axis of the first flow hole 21 is arranged at an angle with the central axis of the second flow hole 31 to change the flow direction of the fluid entering the valve body 1 through the mixing tube and flowing out through the first flow holes 21 and the second flow holes 31.
[0030] The valve body 1 is connected to the mixing pipe. After two or more liquids are collected and mixed in the mixing pipe, they enter the valve body 1 through the mixing pipe. The mixed liquid fluid (hereinafter referred to as fluid) flows out of the valve body 1 after passing through the first flow hole 21 and the second flow hole 31 in the valve body 1. Since the center axis of the first flow hole 21 and the center axis of the second flow hole 31 are at an angle, when the fluid flows through the first flow hole 21 and the second flow hole 31, the flow direction of the fluid changes, causing turbulence in the fluid, thereby making the fluid mixing more uniform, so as to facilitate obtaining a continuous and homogeneous mixed liquid.
[0031] See also Figure 1 and Figure 2 As shown, the first direction X is the axial direction of the valve body 1. The valve body 1 has a first end 101 and a second end 102 opposite to each other along the first direction X. The first end 101 of the valve body 1 is connected to the mixing tube, and the other end of the valve body 1 is connected to the equipment using the mixed liquid. After the mixed liquid flows out of the mixing tube, it flows to the second end 102 of the valve body 1 through the first end 101 of the valve body 1, so that the mixed liquid preliminarily mixed in the mixing tube is transported to the equipment that needs to use the mixed liquid through the valve body 1. In some embodiments, the outer walls of both ends of the valve body 1 along the first direction X are provided with external threads, one end of the valve body 1 is used for threaded connection with the mixing tube, and the other end of the valve body 1 is used for connecting with the equipment using the mixed liquid, which facilitates the disassembly and assembly of the valve body 1 between the mixing tube and the equipment.
[0032] In some embodiments, the first plate 2, the second plate 3 and the valve body 1 are coaxially arranged. The first plate 2 and the second plate 3 are both circular plates, and the outer edges of the first plate 2 and the second plate 3 are connected to the inner wall of the valve body 1 respectively.
[0033] See also Figure 1 As shown, in some embodiments, the central axis of the first flow hole 21 is parallel to the first direction X, and the central axis of the second flow hole 31 is inclined toward the central axis of the valve body 1. Since the first direction X is parallel to the central axis of the valve body 1, the central axis of the first flow hole 21 and the central axis of the second flow hole 31 have a certain angle, and the fluid flowing into the second flow hole 31 through the first flow hole 21 has an obvious change in the flow direction of the fluid, so that the fluid generates turbulence, which is more conducive to the uniform mixing of the fluid. In other embodiments, the setting of the first flow hole 21 and the setting of the second flow hole 31 can be reversed. For example, the central axis of the first flow hole 21 is inclined toward the central axis of the valve body 1, and the central axis of the second flow hole 31 is parallel to the first direction X.
[0034] In some embodiments, a plurality of first flow holes 21 are arranged at equal intervals along the circumference of the first plate 2, and a plurality of second flow holes 31 are arranged at equal intervals along the circumference of the second plate 3, so as to facilitate the production and molding of the first plate 2 and the second plate 3. A plurality of first flow holes 21 are arranged in a circle along the circumference of the first plate 2, and a plurality of second flow holes 31 are arranged in a circle along the circumference of the second plate 3. In other embodiments, a plurality of first flow holes 21 can also be arranged in multiple circles on the first plate 2, and a plurality of second flow holes 31 can be arranged in multiple circles on the second plate 3, so as to increase the flow area and improve efficiency.
[0035] See also Figure 1 As shown, in some embodiments, a guide portion 22 is formed on one side of the first plate 2 away from the second plate 3, and the guide portion 22 is protruded in the direction away from the second plate 3 along the first direction X, so as to form a guide surface 221 on the outer peripheral side of the guide portion 22 to guide the first flow hole 21. The fluid entering the valve body 1 flows to the guide portion 22, and flows to the first flow hole 21 through the guide surface 221 of the guide portion 22, and the guide surface 221 plays a guiding role in the flow of the fluid. A plurality of first flow holes 21 are arranged on the outer peripheral side of the guide portion 22.
[0036] See also Figure 1 and Figure 2As shown, in some embodiments, the inner wall of the valve body 1 is formed with a stop surface 12, and one side of the second plate 3 abuts against the stop surface 12. The stop surface 12 stops the second plate 3, preventing the second plate 3 from axially moving out of the valve body 1 under the impact of the fluid. The inner wall of the valve body 1 is provided with a step, and the step surface of the step forms the stop surface 12. The first plate 2 and the second plate 3 are both arranged on the same side of the stop surface 12. The inner diameter of the valve body 1 on one side of the stop surface 12 (the side where the second plate 3 is arranged) is larger than the inner diameter of the valve body 1 on the other side of the stop surface 12.
[0037] See also Figure 1 As shown, in some embodiments, the in-line mixing valve further includes a first stopper 4, which is installed in the fluid channel 11 and connected to the valve body 1. The first stopper 4 is provided on the side of the first plate 2 away from the second plate 3, and the first stopper 4 abuts against the first plate 2 to provide a pressing force to the first plate 2 along the first direction X. The first plate 2 and the second plate 3 are confined in the space between the first stopper 4 and the stop surface 12, and the first stopper 4 provides a pressing force to the first plate 2, so that the first plate 2 and the second plate 3 abut against the stop surface 12 along the first direction X, thereby preventing the first plate 2 and the second plate 3 from having a large axial movement under the impact of the fluid, thereby affecting the normal flow of the fluid.
[0038] In some embodiments, the first stopper 4 is an elastic retaining ring, and a portion of the first stopper 4 is embedded in the inner wall of the valve body 1. The first stopper 4 has a certain elasticity, which facilitates the disassembly and assembly of the first plate 2 and the second plate 3.
[0039] See also Figure 1As shown, in some embodiments, the online mixing valve further includes a second stopper 5, which is installed in the fluid channel 11 and connected to the valve body 1, and the second stopper 5 abuts against the first plate 2 and the second plate 3 on two opposite sides along the first direction X; a flow passage 51 is formed in the middle of the second stopper 5, and the flow passage 51 connects the first flow hole 21 and the second flow hole 31. The fluid enters the flow passage 51 through the first flow hole 21, then enters the second flow hole 31 through the flow passage 51, and flows out through the second flow hole 31, and the flow passage 51 provides a buffer space for the fluid flow. In addition, the first plate 2 is arranged between the first stop member 4 and the second stop member 5, and the second plate 3 is arranged between the second stop member 5 and the stop surface 12. The first stop member 4, the second stop member 5, and the stop surface 12 jointly define the movable space of the first plate 2 and the second plate 3 to prevent the first plate 2 and the second plate 3 from axially moving under the impact of the fluid. In this case, the first plate 2 and the second plate 3 can be movably installed in the valve body 1 without being connected to the valve body 1. Under the impact of the fluid, the positions of the first plate 2 and the second plate 3 in the axial direction can also remain stable. The first plate 2 is separated from the second plate 3 by the second stopper 5. Even if the first plate 2 and the second plate 3 rotate circumferentially, due to the provision of the second stopper 5 and its flow channel 51, it is possible to avoid the first flow hole 21 and the second flow hole 31 being completely misaligned when the first plate 2 and the second plate 3 are fitted together, so that the first flow hole 21 is blocked by the second plate 3 and the second flow hole 31 is blocked by the first plate 2, resulting in the blockage of the fluid, thereby ensuring that the fluid flows from the first flow hole 21 to the second flow hole 31, and changing the flow direction of the fluid to cause turbulence in the fluid. The structural arrangement of the stop surface 12, the first stop member 4, and the second stop member 5 facilitates the installation of the first plate member 2 and the second plate member 3. The second plate member 3, the second stop member 5, and the first plate member 2 are placed in sequence in the valve body 1. The second plate member 3, the second stop member 5, and the first plate member 2 are abutted against the stop surface 12 through the first stop member 4. The second plate member 3, the second stop member 5, and the first plate member 2 may not be connected to the valve body 1. Combined with the arrangement of the elastic retaining ring, disassembly and assembly are convenient.
[0040] The working process of the utility model is:
[0041] When in use, the end of the valve body 1 is connected to the mixing tube, which preliminarily mixes two or more liquids to form a mixed liquid fluid. After the fluid enters the valve body 1, it flows out of the valve body 1 through the first flow hole 21 and the second flow hole 31 in sequence. In the process of the fluid flowing through the first flow hole 21 and the second flow hole 31, the flow direction of the fluid is changed by the first flow hole 21 and the second flow hole 31, so that the fluid generates turbulence, enhances the mixing intensity of multiple liquids in the fluid, and makes the fluid mix more evenly, so as to obtain a homogeneous mixed liquid through the valve body 1.
[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
