Servo valve pilot stage will produce abrasion at work, but the jet pipe and nozzle baffle compared to produce the degree of erosion and performance changes lower than the nozzle flapper valve. This is because in the case of a jet pipe, the distance between the end face of the nozzle and the receiving hole is 1.5 to 2.5 times the diameter of the nozzle, and in terms of characteristics, this distance is 3.5 times the diameter of the nozzle and also fully usable. In contrast, in the case of the nozzle baffle, the clearance between the nozzle baffles has an upper limit of the characteristic of 1/16 of the diameter, and it is easy to increase the minimum size to 1/16 the limit value Abrasion and changes in properties occur. And in the case of dual nozzle baffle, the two nozzles and the baffle generated by the left and right side of the erosion is not necessarily symmetrical, prone to zero offset. The jet tube jet is jetted by a single nozzle, and is accepted by the hole is divided into two shares, the generation of abrasion is generally symmetrical, the amount of erosion generated than the nozzle baffle less. Coupled with the sharp edge of its receptor even after long-term erosion by high-pressure oil depression, but still its watershed role, as long as its distance from the nozzle is not greater than 3.5 times the nozzle diameter, the performance of the servo valve is very small, so Its stability, reliability, higher than the dual nozzle flapper valve.
