[0016] like Figs. 1 to 5 The aforementioned stepless adjustment structure for a medium-pressure valve includes a valve body 10. One end of the valve body 10 is provided with a stepless adjustment component 20. The stepless adjustment component 20 includes a bracket 21, a knob 22, and a transmission core 23. The transmission core 23 is disposed in the knob 22 and has an external thread on its outer periphery. One side of the bracket 21 is fixedly connected to the valve body 10. The bracket 21 has a hollow structure 24 inside, and the inner wall of the hollow structure 24 has an internal thread. The transmission core 23 is disposed in the hollow structure 24, and the external thread of the transmission core 23 is screwed into the internal thread of the bracket 21. The valve body 10 is adjusted for closing, low gear, and high gear through thread transmission, making the operation smooth and without any jerking.
[0017] The transmission core 23 has an open retaining ring 25 fitted on one side of the external thread. The open retaining ring 25 engages with the edge of the opening of the hollow structure 24. During use, when the transmission core 23 is screwed and rotated between the support 21 to adjust its position, the open retaining ring 25 can prevent the transmission core 23 from disengaging from the support 21.
[0018] The transmission core 23 is connected to the knob 22 by a cross-slot cylindrical head screw 26. The knob 22 is provided with a diaphragm cover 27 on the outside of the screw 26. When in use, the diaphragm cover 27 can cover the screw 26 to make the product more aesthetically pleasing.
[0019] The transmission core 23 has an adjustment channel 28 inside, the inner wall of the adjustment channel 28 has an internal thread, the outer circumference of the adjustment screw plug 30 has an external thread, the external thread of the adjustment screw plug 30 is screwed into the internal thread of the transmission core 23, and a pressure adjusting spring 11 is provided between the adjustment screw plug 30 and the valve body 10. In use, the elastic force of the pressure adjusting spring 11 can be adjusted by adjusting the movement of the adjustment screw plug 30 in the transmission core 23.
[0020] The bracket 21 is connected with the valve body 10 through cross slot cylinder head screw screwing.
[0021] In conclusion, the stepless adjusting structure of the medium pressure valve, the transmission core 23 in the knob 22 is connected with the bracket 21 through the thread rotating structure, the technical problem that the operation is strong is solved, the smooth transition mode is realized to realize closing, middle block, high block adjustment, and the consumer has good operation hand feeling experience.
