Detailed Implementation The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0011] like Figure 1-3As shown, an automatic pressure relief explosion-proof instrument includes a main body 1. The main body 1 is equipped with a connecting pipe 2, a docking platform 3, a pressure relief seat 4, and a drive shaft 5. The connecting pipe 2 is integrally formed and connected to the middle of the rear end of the outer side of the main body 1. The docking platform 3 is integrally formed and connected to the left end of the main body 1. The docking platform 3 is provided with an inner docking platform 6 and an instrument cover 7. The inner docking platform 6 is integrally formed and connected to the inner side of the docking platform 3, and an instrument panel 8 is adhered to the inner docking platform 6. The instrument cover 7 is threaded to the outer side of the docking platform 3. The pressure relief seat 4 is integrally formed and connected to the upper front end of the main body 1. The drive shaft 5 is rotatably connected to the middle of the main body 1. The left end of the drive shaft 5 passes through and extends to the left side of the instrument panel 8, where an instrument pointer 9 is fixed with screws. A drive gear 10 is integrally formed and connected to the middle section of the drive shaft 5. A piston 11 is nested inside the connecting pipe 2, and a first pressure relief pipe is welded to the middle of the piston 11. 12. The front end of the first pressure relief pipe 12 is a closed structure. The first pressure relief pipe 12 is provided with a bearing seat 13, a transmission rack 14 and a second pressure relief pipe 15. The bearing seat 13 is slidably connected to the front end of the first pressure relief pipe 12. The transmission rack 14 is fixed to the lower part of the front end of the first pressure relief pipe 12 by screws, and the transmission rack 14 is meshed with the transmission gear 10. The second pressure relief pipe 15 is welded to the upper part of the front end of the first pressure relief pipe 12. The bearing seat 13 is fixed to the inside of the main body 1 by screws. A spring 16 is fitted on the first pressure relief pipe 12 between the bearing seat 13 and the piston 11. A through hole 17 is opened in the middle of the pressure relief seat 4. The front end of the through hole 17 extends to the outside of the main body 1. The second pressure relief pipe 15 is nested in the through hole 17. The front end of the second pressure relief pipe 15 is a closed structure. A pressure relief hole 18 is opened on the front end of the outer side of the second pressure relief pipe 15. Specific usage: The main body 1 is threaded onto the equipment via the connecting pipe 2; the pressure inside the equipment enters the first pressure relief pipe 12, simultaneously driving the piston 11 to move inward along the connecting pipe 2. The inward movement of the piston 11 compresses the spring 16 and also drives the first pressure relief pipe 12 to move inward. The inward movement of the first pressure relief pipe 12 drives the transmission rack 14 and the second pressure relief pipe 15 to move inward simultaneously. The inward movement of the transmission rack 14 drives the transmission gear 10 to rotate. The rotation of the transmission gear 10 drives the transmission shaft 5 to rotate. The rotation of the transmission shaft 5 drives the instrument pointer 9 to rotate to display the pressure; the inward movement of the second pressure relief pipe 15 drives the pressure relief hole 18 to move outward along the through hole 17. When the pressure is too high, the pressure relief hole 18 moves outward through the through hole 17 to relieve the pressure.
