Taiwan's supply of pilot solenoid valve direct acting solenoid valve pneumatic solenoid valve

Pneumatic solenoid valve according to the gas flow direction of the pipe, if only to allow gas to flow in one direction, this is called a one-way valve solenoid valve, works can be divided into direct-acting valves and pilot valve, direct-acting solenoid valve is to rely on human or force, air force direct realization of reversing valve required; pilot valve is composed of two parts of the pilot head and valve body, there is the head of the piston-driven pilot valve body inside the valve stem to achieve commutation. What is the pneumatic solenoid valve, for the average person probably does not know much about, it is estimated pneumatic solenoid valve is only relating to people would know. Pneumatic solenoid valve works then what is? Solenoid valve for controlling fluid automation infrastructure components, belonging to the actuator; not limited to hydraulic and pneumatic. Solenoid valve for controlling the direction of hydraulic flow, mechanical plant are usually controlled by hydraulic cylinder, so it will use the solenoid valve solenoid valve works, the solenoid valve in a sealed chamber, at different locations with holes, each hole leads to a different intermediate pipeline valve chamber is two is two electromagnets, which the magnet coil is energized body surface to which side will be attracted to a different file live or leaked drain hole by controlling the body's movement , and into the hole is normally open hydraulic oil will enter a different outlet pipe and then through the oil pressure to push oil just the piston, and drive the piston rod drive mechanism moving. Thus by controlling the solenoid current to control the mechanical movement. Traced the history of the solenoid valve, so far, the solenoid valve at home and abroad from the principle divided into three categories (ie: direct acting, pilot-step children) and with the principles from different valve configurations and materials on the the difference is divided into six branches categories (direct-acting diaphragm structure, step by step re-sheet structure, the structure of the pilot film, direct-acting piston structure, step by step direct-acting piston structure, the pilot piston structure) direct acting solenoid valve principle: energized, the electromagnetic coil to generate an electromagnetic force the closing member is lifted from the valve seat, the valve opens; when power, the electromagnetic force disappears, the spring pressure in the seat closure member, the valve closes. Features: vacuum, negative pressure, zero pressure can work, but generally not more than 25mm diameter distribution of direct-acting solenoid valve principle: the principle of a direct-acting and pilot-operated combination, when there is no pressure when the inlet and outlet, power, the electromagnetic force directly to the pilot valve and main valve closure member in turn lift, the valve opens. When the inlet and outlet reaches the starting pressure, the power, the electromagnetic force small pilot valve main valve chamber under increased pressure, the chamber pressure drops, to take advantage of the upward pressure of the main valve open; power, the pilot valve with a spring force or medium pressure to promote off pieces, moving down, the valve closes. Features: zero pressure or vacuum, high pressure can also be action, but power is larger, the requirements must be mounted horizontally. A single-acting cylinder
