[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 A schematic diagram of a preferred embodiment of the safety pressure relief device for alloy powder production provided by this utility model; Figure 2 for Figure 1 The diagram shows a partial sectional view. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 1The diagram shows the exploded structure. Figure 6 for Figure 5 The enlarged schematic diagram of section C is shown below; Figure 7 for Figure 5 The diagram shown is an enlarged view of part D. The safety pressure relief device for alloy powder production includes an upper cover 1 and a lower cover 11. The top of the upper cover 1 is provided with several fasteners 12, which penetrate the lower cover 11 and extend to its exterior. The outer surfaces of the fasteners 12 are threadedly connected to the interior of the lower cover 11. The interior of the upper cover 1 is provided with a pressure regulating component 2, which includes two guide grooves 21 formed on the inner wall of the upper cover 1. The interior of the two guide grooves 21 is fixedly connected to two guide rods 22 for enhancing sliding stability. The outer surfaces of the two guide rods 22 are slidably connected to a top cover 23 for downward pressure. The top cover 23 rotates internally. A screw 24 is connected, which penetrates the upper cover 1 and extends to its exterior. The outer surface of the screw 24 is threadedly connected to the interior of the upper cover 1. A limiting ring 25 for preventing displacement is fixedly connected to the outer surface of the screw 24. A limiting block 26 for limiting is fixedly connected to the bottom of the screw 24. An elastic element 27 is provided inside the top cover 23. A receiving cover 28 is provided inside the lower cover 11. A pressure block 29 for venting is slidably connected inside the receiving cover 28. The top of the pressure block 29 is fixedly connected to the bottom of the elastic element 27. A stabilizing component 3 for maintaining stable rotation is provided on the top of the upper cover 1. A locking component 4 is provided on the top of the upper cover 1.

[0024] The upper cover 1 and the lower cover 11 are fastened together by fasteners 12. The outer surface of the screw 24 is threaded to the inside of the upper cover 1. When the screw 24 is rotated, it can move up and down inside the upper cover 1. The range of motion is limited by the top cover 23 between the limiting ring 25 and the limiting block 26. When the screw 24 moves downward, the limiting ring 25 can press down on the top cover 23, which increases the pressure of the elastic element 27 inside the top cover 23 and increases the downward pressure of the pressure block 29. This allows pressure to be released only when the pressure of the alloy powder production exceeds the pressure of the elastic element 27.

[0025] Among them, the elastic element 27 includes, but is not limited to, springs and rubber;

[0026] In this example, the elastic element 27 is preferably a spring. The spring has high temperature resistance and elastic recovery capability.

[0027] The stabilizing component 3 includes a rotating groove 31, which is opened on the top of the upper shell cover 1. A rotating block 32 for rotation is rotatably connected inside the rotating groove 31. Three support pillars 33 for support are fixedly connected to the top of the rotating block 32. A locking ring block 34 for locking is fixedly connected to the top of the three support pillars 33. The interior of the ring block 34 is threadedly connected to the outer surface of the screw 24.

[0028] The screw 24 is threadedly connected to the ring block 34, which allows the screw 24 to be locked in position. The ring block 34 is supported by the support column 33. The rotating block 32 can rotate inside the rotating groove 31, providing stable rotation support for the control component 2.

[0029] The locking assembly 4 includes a plurality of insertion holes 41 and a locking plate 42. The plurality of insertion holes 41 are arranged in a circumferential array on the outside of the screw ring block 34. The locking plate 42 is installed on the top of the upper shell cover 1. An elastic pin component 43 is slidably connected inside the locking plate 42. The elastic pin component 43 passes through the locking plate 42 and extends to its outside. The end of the elastic pin component 43 is inserted into the inside of the insertion hole 41.

[0030] After the screw 24 is rotated to the appropriate position, the position of the control component 2 is fixed by inserting the elastic pin component 43 into the socket 41 on the outside of the screw ring block 34.

[0031] A drive assembly 5 is provided on the outside of the support column 33. The drive assembly 5 includes three connecting blocks 51. The three connecting blocks 51 are installed on the outside of the three support columns 33. The ends of the three connecting blocks 51 are fixedly connected to a rotating ring 52 for driving. A plurality of grinding blocks 53 for increasing friction are fixedly connected to the outer side of the rotating ring 52.

[0032] The grinding block 53 enables the rotating ring 52 to drive the support column 33 connected to the connecting block 51 to rotate, thereby enabling the stabilizing component 3 to rotate.

[0033] A sealing assembly 6 is provided inside between the upper cover 1 and the lower cover 11. The sealing assembly 6 includes two sealing grooves 61 and two sealing blocks 62. The two sealing grooves 61 are opened at the bottom of the upper cover 1, and the two sealing blocks 62 are installed at the top of the lower cover 11. The two sealing blocks 62 are inserted into the interior of the two sealing grooves 61.

[0034] When the upper cover 1 and the lower cover 11 are installed using fasteners 12, the sealing groove 61 and the sealing block 62 can be inserted, increasing the sealing performance between the upper cover 1 and the lower cover 11.

[0035] A pressure control component 7 is provided on the outside of the upper cover 1. The pressure control component 7 includes a pressure scale 71 and an arrow 72. The pressure scale 71 is installed on the top of the upper cover 1, and the arrow 72 is installed on the top of the screw 24.

[0036] The current pressure value of the elastic element 27 can be determined by using the arrow 72 on the screw 24 in conjunction with the pressure scale 71.

[0037] The working principle of the safety pressure relief device for alloy powder production provided by this utility model is as follows: First, the upper cover 1 and the lower cover 11 are tightly connected together by several fasteners 12 located on the top of the upper cover 1. The internal components of the device provide an installation base and protective space. Then, a guide rod 22 is fixed in the guide groove 21 opened in the inner wall of the upper cover 1, and the top cover 23 is slidably connected to the guide rod 22, which can move smoothly in the vertical direction. When the screw 24, which is rotatably connected to the top cover 23 and passes through the upper cover 1, is rotated, the screw 24 will move up and down due to the thread engagement between the screw 24 and the inside of the upper cover 1. The limiting ring 25 and the limiting block 26 restrict the range of motion of the top cover 23. When the screw 24 moves downward, the limiting ring 25 presses down on the top cover 23, thereby compressing the elastic element 27 inside the top cover 23, increasing the pressure of the elastic element 27. This pressure is transmitted through the elastic element 27, causing the pressure block 29 connected to the bottom of the elastic element 27 to also increase. Meanwhile, the stabilizing component 3 provides stable support for the rotation of the regulating component 2. The rotating block 32, rotatably connected within the rotating groove 31, supports the threaded ring block 34, which is threadedly connected to the screw 24, through the support column 33, ensuring the stability of the screw 24 during rotation. Finally, as the internal pressure gradually increases during the alloy powder production process, once the pressure value exceeds the pressure provided by the elastic element 27, the pressure block 29 will overcome the resistance of the elastic element 27 under pressure and slide along the inside of the receiving cover 28 to achieve venting and pressure relief. In addition, the locking component 4 can fix the position of the regulating component 2 after the screw 24 is adjusted to a suitable position by inserting the elastic pin component 43 into the insertion holes 41 of the outer circumferential array of the threaded ring block 34, preventing it from shifting due to vibration or other factors during production and ensuring stable operation of the device.

[0038] Compared with related technologies, the safety pressure relief device for alloy powder production provided by this utility model has the following advantages:

[0039] This utility model provides a safety pressure relief device for alloy powder production. The upper cover 1 and the lower cover 11 are connected by fasteners 12, providing a reliable foundation for the normal operation of the internal components. The regulating component 2 can provide controllable pressure adjustment, which is adjusted according to the alloy powder production. Pressure relief can only be performed when the pressure value reaches the set value. The stabilizing component 3 can provide stable adjustment and rotation for the regulating component 2. The locking component 4 can lock the regulating component 2 after the pressure adjustment is completed, preventing the regulating component 2 from malfunctioning due to vibration.
