Using a flow valve with a stable flow rate has many benefits, including controlling flow, maintaining system stability, improving efficiency, protecting equipment, and meeting specific process or production requirements. Therefore, it is widely used in engineering and manufacturing fields.
[0003] Traditional flow valves usually adopt a design that allows liquid to directly enter the valve body. This design will cause impact when the liquid flows in, which will affect the stability of the flow and make the measurement inaccurate. In addition, traditional speed regulating valves are often unable to accurately adjust and control the liquid flow, making it impossible to meet the precise flow requirements under specific processes or production requirements. Due to excessive flow rate, it may also cause waste of energy and materials, increasing production costs.
[0004] Therefore, a flow valve with stable flow is proposed, which can solve the problems of unstable flow, low precision and inability to accurately adjust the traditional speed control valve, so as to improve the efficiency and stability of the system and reduce production costs.

[0022] 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.
[0023] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a flow valve with stable flow, including a shell 1, a flow block 2 is fixedly connected inside the shell 1, a flange piece 1 3 is fixedly connected to the outer wall of the shell 1, a flange piece 2 4 is slidably connected inside the shell 1, a transmission shaft 5 is rotatably connected inside the flange piece 2 4, a handle 6 is fixedly connected to the upper surface of the transmission shaft 5, a resistance block 7 is fixedly connected to the lower surface of the transmission shaft 5, the resistance block 7 is rotatably connected inside the flange piece 2 4, a screw rod 8 is fixedly connected to the lower surface of the resistance block 7, a fixed block 9 is fixedly connected inside the shell 1, the flange piece 2 4 is slidably connected inside the fixed block 9, and an adjusting component 10 is arranged on the outer wall of the screw rod 8; the adjusting component 10 includes a threaded sleeve 1001, the threaded sleeve 1001 is threadedly connected to the outer wall of the screw rod 8, the threaded sleeve 1001 is slidably connected inside the flange piece 2 4, a valve core 1002 is fixedly connected to the lower surface of the threaded sleeve 1001, and the outer wall of the valve core 1002 is rotatably connected inside the flow block 2;
[0024] Specifically, during operation, by turning the handle 6, the abutment block 7 will drive the screw 8 to rotate inside the flange 2 4. The rotation function of the screw 8 is that, through its spiral structure, the threaded sleeve 1001 slides inside the flange 2 4. This sliding action is not a simple translation, but is precisely controlled according to the rotation direction and angle of the screw 8. As the threaded sleeve 1001 moves, it will further drive the valve core 1002 to slide and rise inside the baffle block 2. The position change of the valve core 1002 directly affects the size of the channel inside the baffle block 2, thereby realizing the precise control of the liquid flow. When the valve core 1002 is lifted to a certain height, the channel inside the baffle block 2 reaches the maximum, and the liquid can flow stably. This design not only ensures the stability of liquid circulation, but also realizes the flexible adjustment of the liquid flow through the precise control of the valve core 1002. Whether it is necessary to increase the flow or reduce the flow, it can be achieved by simply adjusting the handle 6. In addition, due to the compact structure and simple operation of the entire system, it has been widely used in various fluid control occasions.
[0025] Reference Figure 1 and Figure 3 , a plurality of through holes 11 are provided inside the flange 24, and a plurality of telescopic rods 12 are fixedly connected to the upper surface of the flange 24; a mounting plate 14 is fixedly connected to the upper surface of the plurality of telescopic rods 12, and a spring 13 is sleeved on the outer wall of the telescopic rod 12; the upper end of the spring 13 is fixedly connected to the upper surface of the flange 24, and the lower end of the spring 13 is fixedly connected to the lower surface of the mounting plate 14; a fixing ring 15 is fixedly connected to the inner wall of the mounting plate 14, and a plurality of mounting plates 2 16 are fixedly connected to the outer wall of the fixing ring 15; a plurality of mounting plates 2 16 are fixedly connected to the lower surfaces of the plurality of mounting plates 2 16; a plug post 17 is fixedly connected to the lower surfaces of the plug post 17, and a movable cavity 18 is provided inside the plug post 17; a left-right symmetrical sliding plate 19 is slidably connected inside the plug post 17, and the outer wall of the sliding plate 19 is slidably connected to the inner wall of the movable cavity 18, a spring 20 is provided between the two sliding plates 19, and a block 21 is fixedly connected to the outer walls of the two sliding plates 19;
[0026] Specifically, first, when the interior of the housing 1 needs to be installed, the flange 2 4 is slid into the interior of the housing 1. In this process, the flange 2 4 will tightly contact the fixing block 9, thereby forming a preliminary sealing effect. This design not only ensures the cleanliness of the interior of the housing 1, but also avoids the intrusion of impurities that may occur during the maintenance process. Next, in order to more firmly fix the flange 2 4, the engineer will operate the plug 17 and insert it into the interior of the flange 2 4. In this process, the plug 17 will squeeze the block 21, thereby causing the spring 2 20 to shrink. When the plug 17 completely penetrates the flange 2 4, the spring 2 20 will use its own reaction force to push the block 21, so that it tightly contacts the flange 2 4. In this way, the flange 2 4 is firmly fixed inside the housing 1. Finally, in order to further enhance the stability of the fixation, the plug 17 is pulled by the reaction force of the spring 1 13. This operation not only ensures the close fit between the plug 17 and the flange, but also further enhances the stability of the flange 2 4 through the additional fixing effect of the plug 17.
[0027] Working principle: When using the flow valve, the handle 6 is turned to make the resistance block 7 drive the screw rod 8 to rotate inside the flange 2 4. The screw rod 8 is rotated to drive the threaded sleeve 1001 to slide inside the flange 2 4. The threaded sleeve 1001 drives the valve core 1002 to slide and rise inside the flow block 2, thereby achieving the effect of making the liquid flow out through the flow block 2. The lifting height of the valve core 1002 is used to ensure the stable circulation of the liquid. The inside of the housing 1 needs to be installed. During installation, the flange 24 is slid into the shell 1 and sealed by the flange 24 contacting the fixing block 9. At this time, the plug post 17 is inserted into the flange 24 and the spring 20 is squeezed by the clamping block 21 to shrink, thereby achieving the effect of facilitating the installation of the flange 24. When the plug post 17 penetrates the flange 24, the reaction force of the spring 20 pushes the clamping block 21 to contact the flange 24, thereby achieving the effect of fixing the flange 24, and then the plug post 17 is pulled by the reaction force of the spring 13, thereby achieving a further fixing effect.
[0028] 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.
