Electromagnetic linear valve

An electromagnetic linear valve comprising:

• a main valve body having an upper valve body and a lower valve body, said upper valve body and said lower valve body being connected together by ultrasonic welding, said main valve body being divided into an upper valve chamber and a lower valve chamber, the upper valve chamber having an inlet vent and an outlet vent;
• a movable element;
• a spring leaf;
• an electromagnetic unit which drives the movable element in the main valve body;
• and
• a baffle dividing said main valve body into the upper and lower valve chambers, a through hole being formed in the baffle to connect the upper and lower valve chambers, and
• the movable element having a valve plug blocking the through hole on the baffle,
• wherein said electromagnetic unit includes
• a coil,
• a controller board connecting with the coil,
• an iron core,
• a magnet, and
• the steel casing opens upward and has a bottom surface that is fixed on an upward side of a bottom surface belonging to said lower valve body,
• said magnet is fixed on an upward side of the bottom surface of said steel casing,
• said iron core is fixed on an upward side of said magnet,
• said valve plug is fixed to a top of said movable element,
• said spring leaf is connected between said movable element and said main valve body;
• said movable element has a corbelled trunk bulkhead enclosing said iron core and said coil enwinds the corbelled trunk bulkhead,
• wherein said movable element has an axis rod that is at a lower end of said movable element and that threads the iron core, the magnet and then a fixing hole of the frame for position fixing,
• the electromagnetic linear valve further comprising a positioning tube extending upward from the fixing hole, the positioning tube having an outer diameter that is identical to a diameter of a fixing hole in the steel casing and an inner diameter of the positioning tube is identical to a diameter of an end of the axis rod.
