In our daily life, the steam we touch is often divided into two types: 1. The boiler steam - the saturated steam, the saturated steam temperature and pressure are relatively stable, the temperature is lower than 250 ℃ and the working pressure is lower than 1.6Mp. 2, the steam out of the thermal power plant - superheated steam, superheated steam temperature changes in the base pressure of a large temperature up to 400 or more, the working pressure is lower than 4.0Mpa. For the first type of steam, we usually choose the soft-sealed steam solenoid valve as follows: Structural Features: The valve is a pilot-operated secondary open solenoid valve consisting of two main components, the auxiliary valve and the main 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. For the second type of steam, we usually choose the hard seal of the steam solenoid valve as follows: Structural features: The use of metal hard seal to improve the 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. This article Keywords: solenoid valve
Alnico is an alloy of Aluminium, Nickel and Cobalt.It also contains Iron , Copper ,Titanium, Different metal
component constitution will form different magnet properties, application will also change accordingly.
Alnico is produced by sintered or casted technique,Its`surfaces may need machining,or to be ground for a smoother surface finish and looks brightly metallic looking. Casting means can producing AlNiCo forvariety sizes and shapes, Sintered Alnico is subsize and have very tiny tolorance but machanical performance is not good.
The most commonly used Alnico is Alnico5. There are 4 sort of cast Alnico5 plus a singlesort of sintered Alnico5 (sintered Alnico and cast Alnico have slightly different magnetic and mechanical performance). Among the permanent magnetic materials, AlNiCo have the best reversible temperature coefficient, the highest working temperature up to 500 ℃,it has the
hardest and toughest strongness.Most ALNICO Magnet grades are anisotropic (axial / vertical direction add magnetization).The others are isotropic(horizontal direction magnetized and usually have many poles on one magnet) they are weaker on magnetism but offer more options on design and properties.
