Solenoid valve is used to control the flow direction of the basic components of automation, is the actuator; usually used for mechanical control and industrial valves to control the direction of the medium, so as to achieve the control of the valve switch Solenoid valve works: a closed solenoid valve Of the cavity, in different positions are open through-hole, each hole leads to different tubing, the middle of the valve is a valve, on both sides of the two electromagnets, which side of the magnet coil body will be energized to which side will be attracted, By controlling the movement of the valve body to block or leak different oil drain holes, and into the oil hole is normally open, the hydraulic oil will enter the different oil pipes, and then through the oil pressure to promote the cylinder piston, piston and Driven piston rod, piston rod drive mechanical movement. This controls the mechanical movement by controlling the current flow through the electromagnet. Currently used steam solenoid valve, usually after the following two kinds of steam: 1, boiler steam - saturated steam temperature and pressure is relatively stable, the temperature is below 250 ℃, the working pressure is lower than 1.6Mp. Shanghai Valve Manufacturing Co., Ltd. Starou usually use soft-sealed steam solenoid valve is as follows: Structural features: The valve is composed of two major components of the deputy valve and the main valve of the pilot valve opens the second valve. Heat: electromagnetic part of the seal part with special high temperature electrical and sealing materials, and applied a variety of thermal insulation measures. Wear-resistant: reasonable selection, the valve cup and the guide between the clever use of the fluid lubrication, reduce wear and improve life resistance to condensation: steam pipe condensate is an important factor affecting the action of steam solenoid valve, the valve is not affected by condensation . Other uses - soft seal steam solenoid valve solenoid valve can also be widely used in this series of textile, printing, chemicals, plastics, rubber, pharmaceuticals, food, building materials, machinery, electrical appliances, surface treatment and scientific research departments and bathrooms, canteens, air conditioners and other controlled system. 2, the steam out of the thermal power plant - overheated steam temperature pressure base, the maximum temperature up to 400 above the working pressure is lower than 4.0Mpa. Usually use a hard-sealed steam solenoid valve is as follows: Structural features: The use of metal hard-sealed, increased product temperature and service life. Material selection, valve cup and guide the clever clever use of the fluid lubrication, to reduce wear and tear. Other Uses - Hard Seal Steam Solenoid Valve This product has a wide range of common media, which can be used for fluids such as water, light oil, heavy oil, non-corrosive gas and steam respectively. Such as power station suction pipe drainage system and evaporator exhaust system, mainly in the pipeline for two-way automatic adjustment of media and remote control. Working status: Normally closed - Power on, power off normally open - Power off, power off.
