Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0022] A large flow high pressure gas pressure reducer, such as Figure 1 As shown, it includes a base plate 1, the top of the base plate 1 is movably connected to a pressure reducer body 2, the top of the pressure reducer body 2 is fixedly connected to a pressure gauge 3 for detecting pressure, and two pressure gauges 3 are provided symmetrically on the left and right, the two sides of the pressure reducer body 2 are respectively fixedly connected to an air inlet pipe 4 and an air outlet pipe 5, and one side of the air inlet pipe 4 and the air outlet pipe 5 are fixedly connected to a docking mechanism 6.

[0023] When in use, first, after installing the reducer body 2 through the bottom plate 1, the external pipe can be inserted into the fixed end, and the bolt can be rotated at this time. When the bolt is rotated, the movable sleeve 602 will be driven to approach the fixed pipe 601. At this time, the fixed pipe 601 will squeeze one side of the shrink ring 603. At this time, the shrink ring 603 moves inward, thereby driving the rubber pad 604 to wrap and clamp the external pipe, so as to achieve a fixing effect. At the same time, as the external pipe is inserted, the push rod 609 will be pushed, and the push rod 609 will push the sealing ball 607, so that the sealing ball 607 Away from the through slot, the through slot is in an open state, and when the top rod 609 is away, the spring 606 will push the sealing ball 607 back into the through slot again, and the through slot is closed at this time. The docking mechanism 6 can be more convenient for connecting and fixing the air outlet pipe 5 and the air inlet pipe 4 to the external pipeline, thereby reducing the difficulty of personnel's work. At the same time, the sealing ring 605 can prevent the leakage of high-pressure gas. In addition, the docking mechanism 6 can prevent dust or mosquitoes from entering the detector when it is idle in an outdoor environment, thereby affecting the normal operation of internal parts, thereby increasing the service life of the equipment.

[0024] like Figure 2-4 As shown, the docking mechanism 6 includes a fixed tube 601, a movable sleeve 602, a shrinking ring 603, a rubber pad 604 and a sealing ring 605. The movable sleeve 602 is movably connected to one side of the fixed tube 601 through a plurality of bolts, the shrinking ring 603 is fixedly connected to the outer wall of the movable sleeve 602, and the rubber pad 604 is fixedly connected to the inner wall of the shrinking ring 603, and the sealing ring 605 is fixedly connected to the inner wall of the movable sleeve 602. One side of the shrinking ring 603 is set at 45°, and one side of the shrinking ring 603 is movably connected to the inside of one side of the fixed tube 601, and the other side of the fixed tube 601 is fixedly connected to the outlet pipe 5 and the inlet pipe 4. On one side, multiple rubber pads 604 are arranged, and the docking mechanism 6 also includes a spring 606, a sealing ball 607, a sealing plate 608 and a push rod 609. A through groove is opened inside the sealing plate 608, and the sealing ball 607 is movably connected to one side of the through groove, one end of the push rod 609 is movably connected to the inside of the through groove, one end of the spring 606 is fixedly connected to one side of the inside of the fixed tube 601, and the other end of the spring 606 is fixedly connected to the outer wall of the sealing ball 607, the sealing plate 608 is fixedly connected to the inside of the fixed tube 601, the push rod 609 is slidably connected to the inside of the fixed tube 601, and a ventilation groove is opened on the other side of the fixed tube 601.

[0025] After the reducer body 2 is installed through the bottom plate 1, the external pipe can be inserted into the fixed end, and the bolt can be rotated at this time. When the bolt is rotated, the movable sleeve 602 will be driven to approach the fixed pipe 601. At this time, the fixed pipe 601 will squeeze one side of the shrink ring 603. At this time, the shrink ring 603 moves inward, thereby driving the rubber pad 604 to wrap and clamp the external pipe, so as to achieve a fixing effect. At the same time, as the external pipe is inserted, the push rod 609 will be pushed, and the push rod 609 will push the sealing ball 607, so that the sealing ball 607 is away from the through groove. At this time, the through slot is in an open state. When the top rod 609 moves away, the spring 606 will push the sealing ball 607 back into the through slot again. At this time, the through slot is closed. The docking mechanism 6 can make it easier for the air outlet pipe 5 and the air inlet pipe 4 to connect and fix the external pipeline, thereby reducing the difficulty of personnel's work. At the same time, the sealing ring 605 can prevent the leakage of high-pressure gas. In addition, the docking mechanism 6 can prevent dust or mosquitoes from entering the detector when it is idle in an outdoor environment, thereby affecting the normal operation of internal parts, thereby increasing the service life of the equipment.

[0026] Here’s how it works:

[0027] After the pressure reducer body 2 is installed, the external pipe can be inserted into the fixed end, and the bolt can be rotated at this time. When the bolt is rotated, the movable sleeve 602 will be driven to approach the fixed pipe 601. At this time, the fixed pipe 601 will squeeze one side of the shrink ring 603. At this time, the shrink ring 603 moves inward, thereby driving the rubber pad 604 to wrap and clamp the external pipe, so as to achieve a fixing effect. At the same time, as the external pipe is inserted, the push rod 609 will be pushed, and the push rod 609 will push the sealing ball 607, so that the sealing ball 607 is away from the through groove. At this time, the through groove is in an open state. When the push rod 609 is away, the spring 606 will push the sealing ball 607 back into the through groove again, and the through groove is closed at this time.
