Pilot pressure valve structure and function as well as features
Abstract: This paper introduces the best structural mode of pilot pressure valve, which has excellent accuracy and stability. This mode can be used in the conventional pilot relief valve. The sequence valve and pressure reducing valve are unified as a pilot pressure valve with a common pilot valve. Key words: Pilot pressure valve; Optimal structure model; Precise zero-difference control; General-purpose pilot valve; Maximum value of stability margin 1 Introduction The existing pilot-operated pressure valve mostly adopts the mode of introducing technology. Here is a description of the best structure model (patented), its accuracy and stability is excellent. Conventional pilot-operated relief valves, sequencing valves and pressure relief valves have been modified to be pilot pressure valves with a common pilot valve. 2 pilot pressure valve structure, function Figure 1 is the pilot relief valve relief valve structure, the relationship between the parameters are as follows: Kt2 (Y20 + Y2) = p
