[0030] like Figures 1-6 As shown, this utility model discloses a self-operated micro-pressure regulating valve, comprising a regulating valve body 1, a flange 3 on the side of the regulating valve body 1, a housing 2 sleeved on the outside of the flange 3, a sealing strip 4 inside the housing 2, a square plate 14 fixedly connected to the surface of the sealing strip 4, an internally threaded cylinder 15 fixedly connected to the surface of the square plate 14, and two second threaded rods 18 embedded inside the internally threaded cylinder 15. Two first threaded rods 5 are also embedded inside the housing 2. The valve body 1 is further modified by adding a flange 3 to the side of the regulating valve body 1, sleeved on the outside of the flange 3, and a sealing strip 4 inside the housing 2, with a square plate 14 mounted on the surface of the sealing strip 4 and an internally threaded cylinder 15 mounted on the surface of the square plate 14. The inner threaded cylinder 15 has a second threaded rod 18 embedded inside, and the housing 2 has a first threaded rod 5 embedded inside. Before installing the regulating valve, the housing 2 is first installed on the side of the flange 3, and the housing 2 and the sealing strip 4 are directly sleeved on the outside of the flange 3. The first threaded rod 5 is then screwed into the housing 2, which fixes the housing 2 and the sealing strip 4. When the sealing strip 4 needs to be replaced after a long period of use, simply unscrew the second threaded rod 18. Then, the inner threaded cylinder 15 and the sealing strip 4 can be removed directly. The new sealing strip 4 is installed inside the housing 2, and the second threaded rod 18 is inserted into the inner threaded cylinder 15 and tightened to complete the replacement. This makes the sealing of the connection between the regulating valve and the pipeline stronger.

[0031] A first mounting plate 10 is sleeved on the side of the regulating valve body 1, and a second mounting plate 11 is sleeved on the side of the regulating valve body 1. A strip rod 9 is fixedly connected to the side of the first mounting plate 10 and the second mounting plate 11. A protective net 8 is fixedly connected to the side of the strip rod 9. A frame 7 is provided on the outside of the protective net 8. A fixing rod 13 is fixedly connected to the surface of the first mounting plate 10. A ball head 12 is fixedly connected to the top of the fixing rod 13. By sleeved the first mounting plate 10 on the side of the regulating valve body 1, sleeved the second mounting plate 11 on the side of the regulating valve body 1, and installing the strip rod 9 on the side of the first mounting plate 10 and the protective net 8 on the side of the strip rod 9, and adding a frame 7 on the outside of the protective net 8, a fixing rod 13 is installed on the surface of the first mounting plate 10, and a ball head 12 is installed on the top of the fixing rod 13, after the regulating valve is installed, it is only necessary to sleeve the first mounting plate 10 and the second mounting plate 11 on the outside of the regulating valve through the fixing rod 13 and the ball head 12. At this time, the regulating valve body 1 can be protected by the protective net 8. When it is impacted, the protective net 8 can protect it, making its protective effect better.

[0032] The top of the first threaded rod 5 is fixedly connected to a turntable 6. There are two turntables 6. By installing the turntables 6 on the top of the first threaded rod 5, it is convenient to rotate the first threaded rod 5 by holding the turntables 6.

[0033] The top of the second threaded rod 18 is fixedly connected to the top plate 21, the bottom of the top plate 21 is fixedly connected to the extrusion block 19, and the side of the extrusion block 19 is fixedly connected to the rotating rod 20. Since the top plate 21 is installed on the second threaded rod 18, and the extrusion block 19 is installed at the bottom of the top plate 21, and the rotating rod 20 is installed on the side of the extrusion block 19, when it is necessary to fix the sealing gasket, simply hold the rotating rod 20 and rotate the top plate 21 to drive the second threaded rod 18 to rotate, so that the second threaded rod 18 enters the inner threaded cylinder 15, so that the extrusion block 19 extrudes the frame 7, thereby fixing the sealing strip 4.

[0034] The top of the second mounting plate 11 is fixedly connected to the fixing block 16, and the fixing rod 13 is inserted into the fixing block 16. By installing the fixing block 16 on the top of the second mounting plate 11 and inserting the fixing rod 13 into the second mounting plate 11, the second mounting plate 11 is fixed.

[0035] Two rubber rings 17 are embedded inside the fixing block 16. By embedding the rubber rings 17 inside the fixing block 16, it is convenient for the fixing rod 13 to be inserted into the fixing block 16.

[0036] The working principle of this self-operated micro-pressure regulating valve is as follows: When using this regulating valve, before installing the regulating valve body 1, first install the housing 2 on the side of the flange 3. Directly fit the housing 2 and sealing strip 4 onto the outside of the flange 3, and hold the turntable 6 to screw the first threaded rod 5 into the housing 2. This will fix the housing 2 and sealing strip 4 in place. When the sealing strip 4 needs to be replaced due to prolonged use, simply unscrew the second threaded rod 18. At this point, the inner threaded cylinder 15 and sealing strip 4 can be directly removed. Install the new sealing strip 4 inside the housing 2, hold the rotating rod 20, and rotate the top plate 21 to rotate the second threaded rod 18, thus... The second threaded rod 18 enters the inner threaded cylinder 15, causing the extrusion block 19 to press against the frame 7, thus fixing the sealing strip 4. Then, the second threaded rod 18 is inserted into the inner threaded cylinder 15 and tightened to complete the replacement. After the regulating valve is installed, the first mounting plate 10 and the second mounting plate 11 are simply connected to the outside of the regulating valve through the fixing rod 13 and the ball head 12. The fixing rod 13 and the ball head 12 are inserted into the second mounting plate 11, which can then fix the second mounting plate 11. At this time, the regulating valve body 1 can be protected by the protective net 8. When it is impacted, the protective net 8 can protect it, making its protective effect better.
