Embodiment 1
[0030] figure 1 As shown, the digital pressure regulating valve mainly includes a main valve part 1, a pilot valve part 2, and an electromagnetic pilot valve 3.
[0031] like figure 2 As shown, the main valve part includes the main valve body 4, the main valve body 4 is opened with the main valve core chamber K1, the liquid inlet P, and the liquid outlet T, the main valve core chamber K1 is equipped with the main valve core 5, the main valve core 5. There are threaded holes in the inner processing, which is convenient for disassembly and assembly. The main valve core is provided with a return spring 6, which is in a compressed state. The lower end compresses the pilot valve core 5 to reliably seal with the sealing cone surface in the main valve body 4, and the upper end connects with the pilot valve body 7. At the same time, the main valve body 4 is provided with a main valve fluid hole A K2 and a main valve fluid hole B K3.
[0032] like image 3 As shown, the pilot valv...
