ahyieseuoh -10 advance solenoid pilot manual control structure for the engagement

摘要

This relates to a solenoid valve designed to give you switch the direction of a pneumatic or hydraulic, in particular electronic In addition to the control system as the solenoid valves, and so on to give a pneumatic or hydraulic heureumneun changing direction by the manual operation, and the P line and this line so that the through ball and R1,2 communication of the main valve boxes A, B, each line is equipped the main valve; And a spool that was inserted into the through-opening the respective lines; Once the piston has a chamber to combine with the main valve box, and a pilot valve which is in communication with the P-line and line P and the pilot passage communication hole which communicates with the piston chamber; Pilot chamber that was mounted on one side of the box due to the pilot valve to open and close the first electronic operating mechanism East line passage 2P, pilot communication hole; From the upper surface of the pilot valve box with recessed inwardly to have a button to be inserted into the hole to the line P and the pilot passage communicating holes communicate with each other, made of a binary switch manual control panel equipped with the manual control button, the button is elastically biased by a spring into the insertion hole There forming the valve, the manual operation buttons and a pilot passage communicating with the outer peripheral line P gongreul has to give to each of the barrier elements to separate off, a button insertion hole through a passage line P situated on the top of the button insertion hole characterized in that binary communication hole that is equipped such that the air inlet is in communication with the lower center side from a manually operated button located on the top of the barrier elements to be supplied to the pilot chamber P via a passage located in the lower end line.
