Description

Technical Field

[0001] This invention belongs to the field of valve technology, and specifically relates to a valve-based mixing device. Background Technology

[0002] A plug valve is a type of valve that opens and closes by rotating a plug around its center line. Plug valves are generally used to cut off, distribute, and change the direction of media flow. Plug valves are simple in structure, small in size, quick and easy to open and close, and have good sealing performance; therefore, they are widely used in various working conditions requiring flow regulation. While plug valves are widely used due to their simple and convenient operation, because they can only control fluid flow, other regulating functions still need to be developed.

[0003] Fluid mixing is widely used in aerospace, medicine, industry and other fields. Mixing valves are usually installed at the pipe connection where fluid mixing is required to control the fluid flow rate, fluid composition ratio and even the temperature of the mixed fluid. However, if a T-shaped pipe is added to a general pipe connection to achieve the mixing effect, the pipe needs to be modified and the process will be very complicated.

[0004] This invention achieves the mixing of two fluids by modifying the plug valve and embedding a mixing device into the valve core. Summary of the Invention

The mixing device is embedded in the valve core of the plug valve, making it a mixing plug valve with mixing capabilities. This mixing plug valve can more conveniently add a second fluid to the main channel by rotating the adjusting sleeve core to adjust the branch flow channel. The required fluid flow rate can be flexibly adjusted according to the needs of the on-site working conditions, greatly enhancing the functionality and practicality of the plug valve, thereby solving the problems mentioned in the background art.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6This invention provides a valve-based mixing device, including a valve body 26. The valve body 26 includes a vertical cylindrical groove penetrating the center of the top and bottom, and a transverse main flow channel 28 penetrating the vertical cylindrical groove. Both ends of the main flow channel 28 are flanges 27, and flange holes 25 are provided around the flanges 27 to facilitate the installation of a plug valve into the channel. A valve core body 22 is mounted on the valve body 26 from bottom to top through the vertical cylindrical groove. A valve seat base 30 is mounted at the bottom of the valve body 26, and the valve seat base 30 is fixedly connected to the valve body 26 through a valve seat platform 29 at the top, which facilitates the positioning of the valve core body 22. The valve core body 22 has a valve core base 24 at the center of its bottom surface. The valve core base 24 is rotatably connected to the valve seat 29. The outer wall of the valve core body 22 is rotatably fitted with the vertical cylindrical groove of the valve body 26 to achieve stable positioning of the valve core body 22 during rotation. The valve core body 22 has a transversely penetrating center to form a valve core flow channel hole 21, and a longitudinally penetrating center to form a mixing device channel 20 at the top. A double-sided multi-inclined round hole sleeve 1 is installed through the mixing device channel 20. The mixing device channel 20 is tightly fitted with the outer wall of the double-sided multi-inclined round hole sleeve 1 to achieve tight fitting installation of the double-sided multi-inclined round hole sleeve 1 within the mixing device channel 20. The valve core body 22 has two fixing posts 17 on its upper end, which are symmetrically distributed about the center line of the mixing device channel 20. The upper end of the double-sided multi-inclined round hole sleeve 1 has a sleeve frustum 6, which has fixing holes 5 that are fixedly engaged with the fixing posts 17, thereby positioning the double-sided multi-inclined round hole sleeve 1 and the valve core body 22 so that the double-sided multi-inclined round hole sleeve 1 cannot rotate relative to the valve core body 22 and the contact point is sealed. The double-sided multi-inclined round hole sleeve 1 has a partially open channel in the center longitudinal direction to form the inner wall 4 of the sleeve. The inner wall 4 of the sleeve is coaxial with the outer wall of the rotating adjustment sleeve 9 and fits tightly to increase the sealing performance. The lower half of the inclined circular hole sleeve 1 has 28 rows of 9 inclined circular holes 3 on each side. The inclined circular holes 3 completely penetrate the pipe wall of the double-sided multi-inclined circular hole sleeve 1. The inclined circular holes 3 are inclined downward at an angle of 45° with the center line. When the arc straight groove 8 coincides with the inclined circular hole 3, the branch fluid can flow out from the core branch flow channel 11 through the overlapping area. Since the inclined circular hole 3 is inclined downward at an angle of 45° with the center line, the fluid flowing out from the overlapping area will form two jets in opposite directions on both sides of the double-sided multi-inclined circular hole sleeve 1. This will greatly enhance the disturbance of the flow field and make it more conducive to the full mixing of the two fluids.Two switch protrusions 2 extend upwards from the top surface of the sleeve frustum 6. A longitudinal channel is opened at the center of the rotary adjusting sleeve core 9 to form a sleeve core branch flow channel 11. The sleeve core branch flow channel 11 does not penetrate the bottom 7 of the valve core. The rotary adjusting sleeve core 9 is coaxial with the double-sided multi-inclined circular hole sleeve 1. Two symmetrical arc-shaped straight grooves 8 are respectively opened at the lower end of the rotary adjusting sleeve core 9. The arc-shaped straight grooves 8, through the rotation of the rotary adjusting sleeve core 9, work together with the inclined circular holes 3 to adjust the required flow rate of the branch. A sleeve core frustum 12 is provided at the upper end of the rotary adjusting sleeve core 9. Arc-shaped curved grooves are opened on both sides of the sleeve core frustum 12 to form switch rotating holes 10. The sleeve core frustum 12 rotates in cooperation with the switch protrusions 2 through the switch rotating holes 10. By rotating the valve core body 22, the flow characteristics in the main flow channel 28 are controlled. When the valve core flow channel hole 21 does not intersect with the main flow channel 28, the main flow channel 28 is in a fully closed state. When the valve core flow channel hole 21 intersects with the main flow channel 28, the main flow channel 28 is in an open state, and the flow rate in the main flow channel 28 gradually increases as the intersection increases. When the valve core flow channel hole 21 intersects with the main flow channel 28, the switch rotary hole 10 is rotated by rotating the sleeve frustum 12. When the sleeve outlet 8 intersects with the inclined circular hole 3, the branch flow channel is in an open state, and the branch flow rate gradually increases as the intersection of the sleeve outlet 8 and the inclined circular hole 3 increases.

[0027] Please see Figure 1 , 3 7-8, The upper end of the valve core body 22 is provided with a valve core thread 18 and a fixed square post 19. The upper end of the valve core body 22 is connected to a handle 14. The handle 14 forms a tight fit with the fixed square post 19 through a fixed square hole 13. The valve core thread 18 cooperates with the nut thread 16 and the nut body 15 to fix the handle 14. In this embodiment, it is convenient to rotate the valve core body 22 through the handle 14.

[0028] Please see Figure 1 The lower diameter of the vertical cylindrical groove of the valve body 26 is larger than the upper diameter. In this embodiment, it can prevent the valve core body 22 from coming off upwards, while lowering the center of gravity of the equipment and enhancing stability. The wider lower end is also easier to match with the valve seat.

[0029] Please see Figure 1-3 The valve core flow channel hole 21 corresponds to the position of the main flow channel 28 and has the same diameter; in this embodiment, it is beneficial to achieve seamless connection between the valve core flow channel hole 21 and the main flow channel 28.

[0030] Please see Figure 3The valve core flow channel hole 21 is also provided with a mixing device insertion hole 23 at the lower part. The mixing device insertion hole 23 is coaxially and tightly fitted with the bottom end of the double-sided multi-inclined round hole sleeve 1. In this embodiment, the lower ends of the double-sided multi-inclined round hole sleeve 1 and the rotating adjustment sleeve core 9 that do not pass through can be completely hidden in the mixing device insertion hole 23, and the inclined round hole 3 and the arc straight groove 8 can fully intersect with the valve core flow channel hole 21.

[0031] Please see Figure 5-6 The angle between the two ends of the switch rotating hole 10 and the center line of the sleeve core is 110°, and the angle between the two ends of the switch boss 2 and the center line of the sleeve core is 20°. In this embodiment, it is ensured that the switch boss 2 with the same 20° angle can rotate 90° in the limited channel of the switch rotating hole 10 to ensure the complete opening and closing state when adjusting the branch flow.

[0032] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0033] Working principle: The valve core body 22 is rotated by the handle 14 to control the flow characteristics in the main flow channel 28. When the valve core flow channel hole 21 does not intersect with the main flow channel 28, the main flow channel 28 is in a fully closed state. When the valve core flow channel hole 21 intersects with the main flow channel 28, the main flow channel 28 is in an open state. As the intersection gradually increases, the flow rate in the main flow channel 28 will also gradually increase. When the valve core flow channel hole 21 intersects with the main flow channel 28, the switch rotary hole 10 is rotated by rotating the sleeve cylinder 12. When the sleeve outlet 8 intersects with the inclined circular hole 3, the branch flow channel is in an open state. As the intersection of the sleeve outlet 8 and the inclined circular hole 3 gradually increases, the branch flow rate will also gradually increase.

[0034] Although embodiments of the invention have been shown and described, those skilled in the art will recognize that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
