Electric steam boiler

Abstract

The invention discloses a full-automatic electric steam boiler. In a steam-water separator (82), an S-shaped fixation support (23) is used for limiting the positions of a permanent magnet (30) and a temperature-sensing magnetic body (31); and attraction and non-attraction of the temperature-sensing magnetic body (31) and the permanent magnet (30) are used for controlling opening and closing of valve core seal rings to achieve the separation of steam and water and output. The electric steam boiler is characterized in that the third valve core seal ring (17) is round and concave and is in a circular cap shape with the middle provided with a round hole (74) or a circular ring shape; the permanent magnet (30) is inserted in a suction plate (28) and magnetizes in the thickness direction; a pull rod screw (20) is radially fixed by a guide tube (26); a screw plug (5) is used for adjusting the elastic force of a spring (6); a pressure vessel (83) is made from steel tubes; a floating ball liquid level apparatus (72), the steam-water separator (82) and at least one safety valve (56) are arranged on an upper seal head (73); electric heaters (75) are arranged on a lower seal head (61); a tap water inlet tube connector (57) is arranged on one side of the lower end of a shell of the electric steam boiler for water supplementing; and the floating ball liquid level apparatus (72) is used for controlling an intermediate relay ZJ and a contactor CJ to achieve dry burning resistant protection.

Description

technical field [0001] The invention relates to a fully automatic electric steam boiler. Background technique [0002] Chinese patent application number 201610087401.4 discloses a steam generation system: the elasticity of the pressure-limiting spring or the gravity of the steel ball in the steam and water separator, the self-weight of the valve core connected to the upper end of the pull rod, the pull rod, and the permanent strong magnetic block connected to the lower end of the pull rod , and magnetic in water, and the temperature-sensing magnet that loses its magnetism when it encounters steam attracts and separates from the permanent magnet, and jointly controls the sealing ring on the valve core to close or open the upper and lower chambers of the sealing ring. To realize the separation of steam and water in the pressure vessel, the upper part of the valve core is cylindrical, the lower part is with a conical surface, and a circular groove is arranged on the conical sur...

[0002] Chinese patent application number 201610087401.4 discloses a steam generation system: the elasticity of the pressure-limiting spring or the gravity of the steel ball in the steam and water separator, the self-weight of the valve core connected to the upper end of the pull rod, the pull rod, and the permanent strong magnetic block connected to the lower end of the pull rod , and magnetic in water, and the temperature-sensing magnet that loses its magnetism when it encounters steam attracts and separates from the permanent magnet, and jointly controls the sealing ring on the valve core to close or open the upper and lower chambers of the sealing ring. To realize the separation of steam and water in the pressure vessel, the upper part of the valve core is cylindrical, the lower part is with a conical surface, and a circular groove is arranged on the conical surface, and a sealing ring is arranged in the groove. There is an inner wire at the lower end, which is fixedly connected with the upper end of the pull rod. The lower end of the pull rod protrudes from the lower end of the valve cylinder and is coaxially connected with the permanent strong magnetic block. The holes in the cylinder and the cover wall of the pressure vessel are fastened with screw nuts under the cover wall of the pressure vessel; the upper and lower moving ranges of the permanent magnet are limited by the "S"-shaped fixed upper part, and the position of the temperature-sensitive magnet is fixed by the lower part. And be fixed on the pressure vessel wall by the hole on the "S" type fixed frame, such structural defect is: valve port, valve core, sealing ring of valve core, pull rod, permanent strong magnetism and temperature sensing magnet can not necessarily be kept in the on the same axis; in addition, the high-pressure vessel where the electric heater is located has a larger volume
