Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention will be further described:
[0022] Such as figure 1 1. Structural composition and working principle
[0023] The pilot pressure regulating valve consists of two parts, the main valve and the pilot valve, such as figure 1 shown. It consists of main valve body, main valve core, main valve spring, main valve core damping hole, pilot valve body, pilot valve core, pilot valve spring, adjustment handle, buffer hole, pressure introduction hole and diversion hole, etc., such as figure 2 shown.
[0024] Pilot pressure regulating valve structure:
[0025] The main valve adopts a slide valve structure, mainly including the main valve body, the main valve core, the main valve spring and the damping hole of the main valve core. The cavity is connected to form a pressure self-balancing structure, so that the force of the valve core is not affected by the change of the pressure of the conveyed medium. Its cl...
