Description

Technical Field

[0001] This utility model relates to the field of pressure regulating valve technology, specifically an automatic pressure regulating valve for fish bait puffing processing. Background Technology

[0002] Fish bait is widely used in various fishing activities, and it is divided into pellet bait, powder bait, and mixed bait. To improve the state and palatability of fish bait, extruded feed is widely used in its production. Fish bait requires an extrusion process, which involves the raw materials undergoing pre-processing such as crushing, mixing, feeding, conditioning, extrusion, drying, and further processing. Before extrusion, the mixed raw materials are conditioned with steam in a conditioning unit. The conditioned material then enters an extruder for extrusion, where steam and water are used to adjust the extrusion temperature to achieve the ideal state.

[0003] Besides equipment and human factors, the stability of steam pressure significantly affects the quality of material conditioning and puffing. Therefore, it is essential to ensure stable steam pressure. The application of automatic steam pressure regulating valves effectively addresses the issue of poor bait conditioning and puffing. In actual production, steam is generated by a boiler, and the automatic steam pressure regulating valve automatically adjusts the pressure to ensure the stability of the steam required for conditioning and puffing.

[0004] Pressure regulating valves are divided into spring-loaded pressure regulating valves and differential pressure regulating valves. Firstly, spring-loaded valves typically contain an internal spring. The tension of this spring can be adjusted to control the working pressure. When the pressure exceeds a set value, the spring contracts, releasing the pressure through the valve until it returns to the set range. Secondly, differential pressure regulating valves usually have an input and an output end. The pressure difference between them controls the valve's opening and closing. When the input pressure exceeds the set value, the valve automatically closes, reducing the output pressure. Conversely, when the input pressure falls below the set value, the valve opens, increasing the output pressure. Both types of pressure regulating valves require a certain pressure to open and rely on a spring to close the valve, thus failing to achieve precise pressure control. Therefore, we propose an automatic pressure regulating valve for fish bait puffing processing. Utility Model Content

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1 to 6 This utility model provides a technical solution: an automatic pressure regulating valve for fish bait puffing processing, including a valve body 1. One end of the valve body 1 has an outlet 4, and the other end has an inlet 8. Flanges are provided at both the outlet 4 and the inlet 8. In practical application, the valve body 1 is connected to a steam conveying pipeline via the flanges. A support sleeve 16 is coaxially mounted inside the valve body 1 at one end. The outlet 4 must be connected to the support sleeve 16 to ensure the steam conveying channel is open. A plug 17 is movably mounted inside the support sleeve 16, allowing the plug 17 to reciprocate along the axis of the support sleeve 16.

[0026] A support arm 19 is provided in the middle of the valve housing 1. The bottom of the support arm 19 is rotatably connected to the valve housing 1. This application proposes a specific installation method for the bottom of the support arm 19, such as... Figure 4 As shown, a mounting port 10 is provided at the bottom of the valve body 1. The bottom of the mounting port 10 is sealed by a removable end cap 2. The edge of the end cap 2 is fastened to the mounting port 10 with bolts. When installing the support arm 19, the bottom of the support arm 19 extends into the end cap 2 through the mounting port 10. A mounting hole 15 is provided at the bottom of the support arm 19, and a support shaft 20 is provided in the mounting hole 15. The support shaft 20 is movably installed in the mounting hole 15, which is the key to allowing the support arm 19 to rotate.

[0027] The end cap 2 has movable grooves 3 on both sides corresponding to the two ends of the support shaft 20. When the end cap 2 is connected to the bottom of the mounting port 10, the two ends of the support shaft 20 are movably placed in the movable grooves 3, as shown in the details. Figure 5 As shown, the top of the movable groove 3 is sealed by the edge of the mounting port 10, ensuring that both ends of the support shaft 20 remain within the movable groove 3 without coming out, while the support arm 19 can still rotate around the support shaft 20. This design also has the advantage that when installing the support arm 19, simply place the support shaft 20 into the mounting hole 15, then place both ends of the support shaft 20 into the movable groove 3, and finally install the end cap 2 at the bottom of the valve body 1 to complete the assembly.

[0028] Furthermore, the end of the plug 17 near the support arm 19 is movably connected to the middle of the support arm 19, such as... Figure 4 and Figure 5As shown, a strip groove 18 is provided in the middle of the support arm 19. The strip groove 18 is placed inside the U-shaped seat 14, and the strip groove 18 and the U-shaped seat 14 are movably connected by a shaft. The shaft can move freely along the strip groove 18, and an annular seat or bearing can be fitted on the shaft to reduce friction. The end of the U-shaped seat 14 away from the support arm 19 is connected to the end of the plug 17. Figure 4 As shown, the surface of the support sleeve 16 away from the support arm 19 has multiple openings 21. When the support arm 19 swings left and right around the support shaft 20, the support arm 19 will drive the U-shaped seat 14 and the plug 17 to reciprocate within the support sleeve 16, as... Figure 6 As shown, when the support arm 19 swings to the left, the support arm 19 will drive the plug 17 to move outward from inside the support sleeve 16. At this time, the plug 17 separates from the opening 21, allowing the steam in the valve body 1 to enter the outlet 4 through the opening 21; as Figure 5 As shown, when the support arm 19 swings to the right, the support arm 19 will drive the plug 17 to move into the support sleeve 16. At this time, the plug 17 will block the opening 21, thereby preventing steam from flowing out of the opening 21.

[0029] To increase the airtightness between the plug 17 and the support sleeve 16, the end of the plug 17 away from the support arm 19 is made to have a tapered contact surface, and a rubber layer is provided on the surface of the plug 17 to increase the airtightness.

[0030] Furthermore, the valve body 1 has a movable port 11 at the top, and the bottom edge of the sealing cover 12 is detachably connected to the top of the movable port 11. The edge of the sealing cover 12 and the top of the movable port 11 are fastened together by bolts. After the sealing cover 12 is installed, the valve body 1 and the interior of the sealing cover 12 are connected.

[0031] The top of the support arm 19 extends into the sealing cover 12, that is, the top of the support arm 19 extends into the sealing cover 12 from the movable opening 11. The top of the support arm 19 is provided with an armature 13. The two ends of the sealing cover 12 are respectively provided with electromagnets 6 with opposite magnetic properties. The electromagnets 6 are connected to the controller. In actual use, the controller controls the two electromagnets 6 to switch directions at the same time, so that one electromagnet 6 always attracts the armature 13 and the other electromagnet 6 pushes the armature 13, forming a form of attraction and push, so that the armature 13 can swing under the joint action of the two electromagnets 6.

[0032] like Figure 1As shown, pressure sensors 5 are respectively installed at both ends of the valve body 1. Specifically, two pressure sensors 5 are installed on the outlet 4 and the inlet 8, respectively. Holes for installing the pressure sensors 5 are provided at the outlet 4 and the inlet 8, and the pressure sensors 5 are threaded into these holes. The pressure sensors 5 are connected to the electromagnets via the controller. The specific working process is as follows: the inlet 8 is located on one side of the steam generator, and the outlet 4 is located on one side of the puffing device. The pressure sensor 5 on the outlet 4 monitors the pressure of the steam delivered to the puffing device, while the pressure sensor 5 on the inlet 8 monitors the pressure of the steam from the steam generator. When the pressure of the steam on the puffing device side is less than a set value, the controller controls the two electromagnets 6 to drive the armature 13 as follows: Figure 6 As shown, it moves to the left, causing armature 13 to separate plug 17 from opening 21, allowing steam to enter outlet 4. When the steam pressure reaches the preset value, the controller controls the two electromagnets 6 to move armature 13 as shown. Figure 5 As shown, it moves to the right, causing the armature 13 to drive the plug 17 to block the opening 21, thereby preventing steam from flowing into the puffing equipment;

[0033] In actual use, the pressure sensor 5 can accurately monitor the steam pressure on both sides of the valve body 1, so that the steam delivery accuracy is high and the steam pressure delivered to the puffing equipment is more precise.

[0034] It should also be noted that the magnetic poles of electromagnet 6 extend into the sealing cover 12 to prevent the sealing cover 12 from blocking the magnetism. However, the electromagnet 6 and the sealing cover 12 must be sealed. Specifically, a flange is provided at the edge of the electromagnet 6, and the flange is fastened to the sealing cover 12 with bolts to seal and fix it. Since the armature needs to oscillate back and forth frequently during use, a buffer pad 22 is provided at the magnetic pole to prevent the reciprocating armature from making hard contact with the electromagnet 6. A buffer pad can also be provided on the surface of the armature 13.

[0035] Furthermore, such as Figure 1 As shown, the controller is installed inside the control housing 7. The bottom of the control housing 7 has four support legs 9, symmetrically distributed on both sides of the valve housing. The support legs 9 are detachably connected to the valve housing 1, and are specifically fastened to the valve housing 1 with bolts. The surface of the control housing 7 has a display screen and operation buttons, which are connected to the controller. The pressure value of the steam discharged from the valve can be set through the operation buttons, and the pressure value can be displayed on the display screen.

[0036] Based on the above embodiments, it should be further explained that the sealing performance between the plug 17 and the support sleeve 16 is good, and the support sleeve 16 is located on one side of the expansion device. The high-pressure steam located on the side of the steam generator can push the plug 17 against the support sleeve 16, further improving the sealing performance.

[0037] The bottom of the support arm 19 rotates around the support shaft 20. The support arm 19 and the armature 13 are the "lever arms" that drive the plug 17 to move. The lever arm is long, and under the simultaneous switching of the two electromagnets 6, the "lever arms" formed by the support arm 19 and the armature 13 can easily drive the plug 17 to move inside the support sleeve 16.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
