[0015] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects: 1. The gas pressure reducing valve of the present invention has a pressure reducing valve housing arranged. When the pressure reducing valve housing as a whole releases pressure on the reactor, the gas in the reactor body penetrates into the pressure reducing chamber of the pressure reducing valve housing, and then pushes up the insertion section. When the insertion section pushes up, the extension section pushes the compression spring, so that the extension section and the limit section are separated from the sealing gasket. At the same time, the gas pressure in the reactor can be discharged from the pressure reducing chamber. The arranged sealing members are in contact with the valve core and the sealing gasket respectively, which can further improve the sealing performance of the valve core when it is not pushed upward. In addition, By arranging the interlaced section, the extended section and the limiting section into an inverted mountain shape, the sealing of the pressure reducing cavity of the pressure reducing valve housing can be further strengthened, and at the same time, the valve core can be effectively prevented from deflecting when the air pressure from the top rises. In addition, the arranged O-ring can further stabilize the seal. When the valve core shakes and deflects, it can be transmitted to the seal and the seal can be bound by the O-ring. At the same time, by installing a limiting rubber pad in the groove, the stability of the O-ring during use can be further improved. 2. The gas pressure reducing valve of the present invention, through the arrangement of the external plug-in section and the internal plug-in section, can make the internal plug-in section penetrate into the inner wall of the reactor mouth after the reactor mouth is inserted into the clamping cavity formed by the external plug-in section and the internal plug-in section. In short, the thickness of the reactor mouth is equivalent to the thickness of the reactor mouth. The internal plug-in section can penetrate into the inner wall. When the reactor mouth is inserted into the clamping cavity, the cross hole on the reactor mouth can be inserted into the cross lock rod, so that the reactor mouth can be The mouth of the reactor can not only form a limit when it penetrates into the clamping cavity, but also form a secondary cross limit between the cross locking rod in the direction from top to bottom, so as to increase the gas generated by the reactor during pressure relief, so that the pressure reducing valve shell as a whole and the reactor mouth will not fall off. Secondly, the reactor mouth is narrow at the top and wide at the bottom, and the wide part of the reactor mouth can fit with the clamping cavity, while the narrow part of the reactor mouth can continue to move upward, so as to trigger the locking limit component to perform three limit operations on the reactor mouth. 3. The gas pressure reducing valve of the present invention has a locking and limiting component. After the staff pushes the external plug-in section and the internal plug-in section to limit the reactor mouth through the clamping cavity once and the secondary cross limit, after the pressure reducing valve housing moves downward as a whole, the ball head can continue to move downward along the narrow part of the reactor mouth. When the lock core touches the notch of the narrow part of the reactor mouth, it will penetrate into the notch. In this process, the locking rod can be driven to move left at the same time. After the locking rod moves left, since the first inclined surface and the second inclined surface are in contact at the beginning, the upper wedge block pushes the lower wedge block to move downward. After the second electromagnet moves downward, it can contact the reactor body. After the upper wedge block moves to the limit position, the adsorption plate can be displaced onto the first electromagnet. At this time, the first electromagnet and the adsorption plate are in a fit state. By opening The first electromagnet can adsorb the adsorption plate, and the second electromagnet can be turned on to adsorb the reactor body. On the one hand, it can strengthen the connection between the locking and limiting component as a whole and the reactor body and the connection between the lower wedge block and the upper wedge block, and at the same time, it can strengthen the connection between the locking rod as a whole and the reactor mouth. On the other hand, through the stable connection of the locking and limiting component as a whole and the reactor body and the reactor mouth, it can further strengthen the connection between the pressure reducing valve housing as a whole and the reactor, so as to prevent the pressure reducing valve housing as a whole from falling off from the reactor when the reactor is deflated. In addition, through the limiting connection of the locking and limiting component with the reactor and the reactor mouth, it can also promote the stability of the connection between the reactor mouth and the pressure reducing valve housing after the first limiting of the clamping cavity and the second cross limiting. 4. The gas pressure reducing valve of the present invention, through the arranged pressure stabilizing component, when the reactor body is depressurized, the gas in the reactor body flows up to the pressure stabilizer frame through the first conical air hole, penetrates into the space between the pressure stabilizer frame and the built-in plug-in section through the air holes on the side of the pressure stabilizer frame, and penetrates into the pressure reducing chamber of the pressure reducing valve housing through the air holes on the air permeable plate to perform the pressure reducing operation. When the instantaneous air pressure in the reactor rises, the second blocking rod can be squeezed to rise. At the same time, the second blocking rod drives the driven wheel to rotate when rising to drive the first blocking rod to move downward to complete the blocking of the first conical air hole, and the second conical air hole is opened at the same time. Since the opening size of the second conical air hole is larger than that of the first conical air hole, it can reduce the impact of the instantaneous air pressure in the reactor on the valve core and the compression spring in the pressure reducing valve housing. On the one hand, it can effectively prevent the valve core from shaking violently and the compression spring from being damaged due to the instantaneous air pressure increase. On the other hand, it can prevent the pressure reducing valve housing as a whole from falling off from the reactor port due to the instantaneous air pressure increase. On the other hand, when reducing the process of the instantaneous air pressure rising into the pressure reducing valve housing, it can also combine with the locking and limiting component to reduce the upward pulling force on the locking and limiting component, thereby delaying the service life of the locking and limiting component.

[0021] In the embodiment, Figure 1-7A gas pressure reducing valve is provided, which comprises a pressure reducing valve housing 1, which has a pressure reducing chamber, on which a hexagonal nut 11 is detachably mounted, a hexagonal flat-end fastening screw 12 is detachably arranged in the pressure reducing valve housing 1, and the hexagonal flat-end fastening screw 12 is located in the pressure reducing chamber, a flat gasket 13 is detachably arranged below the hexagonal flat-end fastening screw 12, a compression spring 14 is detachably arranged below the flat gasket 13, and an external gasket 2 is detachably arranged on the pressure reducing valve housing 1 ; The sealing member 16 is detachably arranged on the pressure reducing valve housing 1, and has a stage 161, an arc groove 162 and a groove 163 thereon, a step is formed between the stage 161 and the sealing member 16, a sealing rubber pad 17 is detachably arranged on the step, a limiting rubber pad 18 is removably arranged on the groove 163, and an O-ring 19 is removably sleeved on the arc groove 162; the valve core 15 has a vertical section and an interlaced section 151 connected to the vertical section and a The valve core 15 is composed of an extension section 152, the vertical section of the valve core 15 can be inserted into the compression spring 14, and the valve core 15 can be inserted into the compression spring 14 through its vertical section so that the compression spring 14 is limited on the extension section 152, and a limit section 153 is detachably arranged on the extension section 152, and the extension section 152 and the limit section 153 can cover the sealing gasket 17; two sets of external plug-in sections 3, both of which are detachably arranged at the bottom of the pressure reducing valve housing 1; two sets of internal plug-in sections 31, both of which are detachably installed on the pressure reducing valve housing 1 At the bottom of the pressure reducing valve housing 1, a clamping cavity is formed between the built-in plug-in section 31 and the external plug-in section 3 for the reactor mouth to pass through. The built-in plug-in section 31 can penetrate into the reactor mouth so that the gas in the reactor can rush into the pressure reducing cavity of the pressure reducing valve housing 1; a locking and limiting component 4, which is detachably installed on the bottom of the pressure reducing valve housing 1, and is detachably connected to the external plug-in section 3; a pressure stabilizing component 5, which is detachably installed on the two groups of built-in plug-in sections 31, and can penetrate into the reactor mouth.

[0022] The present invention is based on an overall idea that, through the arrangement of the pressure reducing valve housing 1, when the pressure reducing valve housing 1 as a whole relieves the pressure of the reactor, the gas in the reactor body penetrates into the pressure reducing chamber of the pressure reducing valve housing 1, and then pushes up the insertion section 151. After the insertion section 151 is pushed up, the extension section 152 pushes the compression spring 14, so that the extension section 152 and the limiting section 153 are separated from the sealing gasket 17. At the same time, the air pressure in the reactor can be discharged from the pressure reducing chamber. The arranged sealing member 16 is in contact with the valve core 15 and the sealing gasket 17 respectively, which can further improve the sealing performance of the valve core 15 when it is not pushed upward. In addition, by arranging the insertion section 151, the extension section 152 and the limiting section 153 into an inverted mountain shape. The shape can further enhance the sealing of the pressure reducing cavity of the pressure reducing valve housing 1, and can effectively prevent the valve core 15 from deflecting when the air pressure from the top rises. In addition, the arranged O-ring 19 can further stabilize the seal 16. When the valve core 15 shakes and deflects, it can be transmitted to the seal 16 and the seal 16 is bound by the O-ring 19. At the same time, by installing a limiting rubber pad 18 in the groove 163, the stability of the O-ring 19 during use can be further improved. By arranging the external plug-in section 3 and the internal plug-in section 31, after the reactor port is inserted into the clamping cavity formed by the external plug-in section 3 and the internal plug-in section 31, the internal plug-in section 31 can be inserted into the reactor port. In the inner side wall of the kettle mouth, in short, the thickness of the kettle mouth is equivalent to that of the reactor mouth, which penetrates into the clamping cavity, and the built-in plug-in section 31 can penetrate into the inner side wall. When the kettle mouth of the reactor penetrates into the clamping cavity, the cross hole on the kettle mouth of the reactor can be inserted into the cross locking rod 32, so that the kettle mouth of the reactor can not only form a limit when it penetrates into the clamping cavity, but also form a secondary cross limit between the cross locking rod 32 in the top-down direction, so as to increase the gas generated by the reactor during pressure relief, so that the pressure reducing valve housing 1 as a whole and the kettle mouth of the reactor will not fall off. Secondly, the kettle mouth of the reactor is narrow at the top and wide at the bottom. The wide part of the kettle mouth of the reactor can fit into the clamping cavity, and the narrow part of the kettle mouth of the reactor can continue to move upward to trigger the locking limit. The component 4 can perform three limiting operations on the reactor mouth. Through the arranged locking limiting component 4, after the staff pushes the external plug-in section 3 and the internal plug-in section 31 to limit the reactor mouth through the clamping cavity once and the secondary cross limit, after the pressure reducing valve housing 1 is lowered as a whole, the ball head 421 can continue to move downward along the narrow part of the reactor mouth. When the lock core 422 touches the notch of the narrow part of the reactor mouth, it will penetrate into the notch. In this process, it can also drive the locking rod 42 to move left. After the locking rod 42 moves left, since the first inclined surface and the second inclined surface are in contact at the beginning, the upper wedge block 424 pushes the lower wedge block 471 to move downward. After moving downward, the second electromagnet 477 can contact the reactor body.After the upper wedge block 424 moves to the limit position, the adsorption plate 425 can be displaced onto the first electromagnet 472. At this time, the first electromagnet 472 and the adsorption plate 425 are in a fitted state. By turning on the first electromagnet 472, the adsorption plate 425 can be adsorbed. By turning on the second electromagnet 477, the second electromagnet 477 can adsorb the reactor body. On the one hand, it can strengthen the connection between the locking limit member 4 as a whole and the reactor body, and strengthen the connection between the lower wedge block 471 and the upper wedge block 424. At the same time, it can strengthen the connection between the locking rod 42 as a whole and the reactor mouth. On the other hand, by locking The locking and limiting connection of the limiting component 4 with the reactor body and the reactor mouth can further strengthen the connection between the pressure reducing valve housing 1 and the reactor to prevent the pressure reducing valve housing 1 from falling off the reactor when the reactor is deflated. In addition, the locking and limiting connection of the limiting component 4 with the reactor and the reactor mouth can also promote the stability of the connection between the reactor mouth and the pressure reducing valve housing 1 after the first limiting of the clamping cavity and the second cross limiting. Through the arranged pressure stabilizing component 5, when the reactor body is depressurized, the gas in the reactor body flows up to the pressure stabilizing machine frame 5 through the first conical air vent 511. 1 and penetrates into the space between the pressure regulator frame 51 and the built-in plug-in section 31 through the air holes on the side of the pressure regulator frame 51 and penetrates into the pressure reducing chamber of the pressure reducing valve housing 1 through the air holes on the air permeable plate 52 to perform the pressure reducing operation. When the instantaneous air pressure in the reactor rises, it can squeeze the second blocking rod 541 to rise. At the same time, when the second blocking rod 541 is rising, it drives the driven wheel 56 to rotate to drive the first blocking rod 534 to move downward to complete the blocking of the first conical air hole 511. At the same time, the second conical air hole 512 is opened. Since the opening size of the second conical air hole 512 is larger than that of the first conical air hole 51 1, so it can slow down the impact of the instantaneous air pressure in the reactor on the valve core 15 and the compression spring 14 in the pressure reducing valve housing 1. On the one hand, it can effectively prevent the valve core 15 from shaking violently and the compression spring 14 from being damaged by the instantaneous air pressure rise. On the other hand, it can prevent the pressure reducing valve housing 1 from falling off from the reactor port as a whole due to the instantaneous air pressure rise. On the other hand, when slowing down the process of the instantaneous air pressure rising into the pressure reducing valve housing 1, it can also combine with the locking and limiting component 4 to reduce the upward pulling force on the locking and limiting component 4, thereby delaying the service life of the locking and limiting component 4.

[0023] In some embodiments, more specifically, in order to further improve the stability of the sandwich cavity formed between the reactor opening and the external plug-in section 3 and the internal plug-in section 31, so as to prevent the gas in the reactor from causing the pressure reducing valve housing 1 to fall off from the reactor as a whole when the pressure is released, a cross lock rod 32 is detachably installed at the bottom of the pressure reducing valve housing 1, and the size of the cross lock rod 32 is adapted to the size of the pressure reducing valve housing 1, and the cross lock rod 32 can be inserted into the reactor opening so that the cross lock rod 32 is positioned in the reactor opening; It should also be noted that after the reactor mouth is inserted into the clamping cavity formed by the external plug-in section 3 and the internal plug-in section 31, the internal plug-in section 31 can be inserted into the inner wall of the reactor mouth. In short, the thickness of the reactor mouth is inserted into the clamping cavity, and the internal plug-in section 31 can be inserted into the inner wall. When the reactor mouth is inserted into the clamping cavity, the cross hole on the reactor mouth can be inserted into the cross locking rod 32, so that the reactor mouth can not only When penetrating into the clamping cavity, a limit is formed, and a secondary cross limit can be formed between the cross locking rod 32 in the top-down direction to increase the gas generated by the reactor during pressure relief so that the pressure reducing valve housing 1 as a whole and the reactor mouth appear to fall off. Secondly, the reactor mouth is narrow at the top and wide at the bottom. The wide part of the reactor mouth can fit into the clamping cavity, and the narrow part of the reactor mouth can continue to move upward to trigger the locking limit component 4 to perform three limit operations on the reactor mouth.

[0024] In some embodiments, more specifically, in order to enable the valve core 15 to squeeze the compression spring 14 and deform when moving upward, the vertical section of the valve core 15 does not completely penetrate the compression spring 14, and the caliber size of the vertical section of the valve core 15 is adapted to the caliber size of the compression spring 14.

The upper panel 46 is located above the lower panel 45; the linkage rod 47 can pass through the upper panel 46 and the lower panel 45 in sequence, and a lower wedge block 471 is detachably installed on the linkage rod 47, and the lower wedge block 471 is in conflict with the upper wedge block 424. The block 471 has a second inclined surface, a first electromagnet 472 is detachably mounted on the upper part of the lower wedge block 471, an ear plate 473 is detachably mounted on the middle part of the linkage rod 47, a slide bar 474 is detachably mounted on the ear plate 473, the slide bar 474 can pass through the upper panel 46, a stop block 475 is detachably mounted on the slide bar 474, the stop block 475 is located below the upper panel 46, a second spring 476 is sleeved on the slide bar 474, and a second electromagnet 477 is detachably mounted on the bottom of the linkage rod 47; Next, the overall working principle of the locking and limiting component 4 is further explained. After the staff pushes the external plug-in section 3 and the internal plug-in section 31 to limit the reactor mouth through the clamping cavity once and the secondary cross limit, after the pressure reducing valve housing 1 moves downward as a whole, the ball head 421 can continue to move downward along the narrow part of the reactor mouth. When the lock core 422 touches the notch of the narrow part of the reactor mouth, it will penetrate into the notch. In this process, the locking rod 42 can be driven to move left at the same time. After the locking rod 42 moves left, since the first inclined surface and the second inclined surface are in contact at the beginning, the upper wedge block 424 pushes the lower wedge block 471 to move downward. The second electromagnet 477 can contact the reactor body after moving downward. When the upper wedge block 424 moves to the limit position, the adsorption plate 425 can be displaced to the first electromagnet 472. At this time, the first electromagnet 472 is in contact with the adsorption plate 425. In the closed state, the adsorption plate 425 can be adsorbed by turning on the first electromagnet 472, and the reactor body can be adsorbed by the second electromagnet 477. On the one hand, the connection between the locking limit component 4 and the reactor body and the connection between the lower wedge block 471 and the upper wedge block 424 can be strengthened, and at the same time, the connection between the locking rod 42 and the reactor mouth can be strengthened. On the other hand, the connection between the pressure reducing valve housing 1 and the reactor can be further strengthened through the stable connection between the locking limit component 4 and the reactor body and the reactor mouth. This prevents the pressure reducing valve housing 1 from falling off the reactor when the reactor is deflated. In addition, the limiting connection between the locking limit component 4 and the reactor and the reactor mouth can promote the stability of the connection between the reactor mouth and the pressure reducing valve housing 1 after the first limiting of the clamping cavity and the second cross limiting.

[0026] In some embodiments, more specifically, in order to facilitate the second electromagnet 477 to pass through the bottom frame 451, the second electromagnet 477 is located below the lower panel 45, and the second electromagnet 477 is located inside the bottom frame 451. In the initial position, the second electromagnet 477 is located above the lowest point of the bottom frame 451.

[0027] In some embodiments, more specifically, the size of the second spring 476 is compatible with the size of the slide bar 474, and the second spring 476 is located between the ear plate 473 and the upper panel 46. In the initial position, the limit block 475 does not contact the upper panel 46.

[0028] In some embodiments, in order to further improve the stability of the connection between the outer jacket frame 41 and the reactor body, a locking rod 48 is detachably installed at the bottom of the outer jacket frame 41, and the size of the locking rod 48 is adapted to the size of the outer jacket frame 41. By inserting the locking rod 48 into the reactor body, the stability of the connection between the outer jacket frame 41 and the reactor body can be further improved.

[0029] Next, the voltage stabilizing component 5 as a whole is given a more specific structure and construction for further explanation. The voltage stabilizing component 5 includes a voltage stabilizing machine frame 51, on which a breathable plate 52 is formed integrally, a plurality of breathable holes are provided on the breathable plate 52, and the breathable plate 52 is seamlessly connected to the built-in plug-in section 31. A first conical breathable hole 511 and a second conical breathable hole 512 are provided at the bottom of the voltage stabilizing machine frame 51, and the diameter of the second conical breathable hole 512 is larger than the diameter of the first conical breathable hole 511; a voltage stabilizing substrate 53, which is detachably installed in the voltage stabilizer frame 51, and a first lower extension plate 531 and a second lower extension plate 532 are detachably arranged on it, and a blocking plate 533 is detachably arranged in the cavity formed by the first lower extension plate 531 and the second lower extension plate 532, and the blocking plate 533 is respectively connected to the first lower extension plate 531 and the second lower extension plate 532, and a first blocking rod 534 is slidably arranged between the first lower extension plate 531 and the second lower extension plate 532, and the first blocking rod 534 is slidably arranged from top to bottom along the length direction thereof. A first gear surface is arranged below, and a first blocking rod 534 can close the first conical air vent 511. In the initial state, the first blocking rod 534 is located above the first conical air vent 511; a clamping plate 54 is detachably installed between the two sets of second lower extension plates 532, and a displacement rod 542 is slidably arranged on the clamping plate 54, and a second blocking rod 541 is detachably arranged on the end of the displacement rod 542 passing through the clamping plate 54, and the second blocking rod 541 is arranged from top to bottom along its length direction. A second gear surface, in the initial state, the second blocking rod 541 closes the second conical vent hole 512, a third spring 543 is removably arranged on the displacement rod 542, and the third spring 543 is located between the clamping plate 54 and the second blocking rod 541, and a sealing plate 544 is also removably arranged on the top of the displacement rod 542; a built-in rotating shaft 55 is rotatably arranged in the voltage stabilizer frame 51, and a driven wheel 56 is removably arranged on it, and the driven wheel 56 is respectively meshed with the first gear surface and the second gear surface; Next, the overall use principle of the pressure stabilizing component 5 is further explained. When the reactor body is depressurized, the gas in the reactor body flows up to the pressure stabilizer frame 51 through the first conical air hole 511 and penetrates into the space between the pressure stabilizer frame 51 and the built-in plug-in section 31 through the air holes on the side of the pressure stabilizer frame 51, and penetrates into the pressure reducing chamber of the pressure reducing valve housing 1 through the air holes on the air permeable plate 52 to perform the pressure reducing operation. When the instantaneous air pressure in the reactor rises, the second blocking rod 541 can be pushed to rise. At the same time, the second blocking rod 541 drives the driven wheel 56 to rotate when rising, so as to drive the first blocking rod 534 to move downward, so as to complete the blocking of the first conical air hole 511. At the same time, the second conical air hole 512 is opened. Since the opening size of the second conical vent hole 512 is larger than that of the first conical vent hole 511, the impact of the instantaneous air pressure in the reactor on the valve core 15 and the compression spring 14 in the pressure reducing valve housing 1 can be reduced. On the one hand, it can effectively prevent the valve core 15 from shaking violently and the compression spring 14 from being damaged due to the instantaneous air pressure increase. On the other hand, it can prevent the pressure reducing valve housing 1 from falling off from the reactor port as a whole due to the instantaneous air pressure increase. On the other hand, when reducing the process of the instantaneous air pressure rising into the pressure reducing valve housing 1, it can also combine with the locking and limiting component 4 to reduce the upward pulling force on the locking and limiting component 4, thereby delaying the service life of the locking and limiting component 4. When the instantaneous air pressure in the reactor drops, the second blocking rod 541 is no longer pushed up. Since the third spring 543 loses its compression, it will push the second blocking rod 541 down to block the second conical air hole 512. At the same time, the second blocking rod 541 drives the driven wheel 56 to move upward, and then continues to open the first conical air hole 511 to achieve the decompression of the gas in the reactor.

[0030] In some embodiments, more specifically, in order to further enhance the sealing effect of the first blocking rod 534 on the first conical air hole 511, the first blocking rod 534 is in conflict with the blocking plate 533 in the initial state, and a first conical thorn head is integrally formed at the bottom of the first blocking rod 534, and the size of the first conical thorn head is adapted to the opening size of the first conical air hole 511.

[0031] In some embodiments, more specifically, in order to further enhance the sealing effect of the second sealing rod 541 on the second conical air hole 512, the weight of the second sealing rod 541 is greater than the weight of the two groups of first sealing rods 534, and a second conical thorn head is integrally formed at the bottom of the second sealing rod 541, and the size of the second conical thorn head is adapted to the opening size of the second conical air hole 512.
