Dual-working-condition electromagnetic valve for water dispenser

Abstract

The invention discloses a dual-working-condition electromagnetic valve for a water dispenser. The dual-working-condition electromagnetic valve for the water dispenser comprises a valve body which is provided with a water inlet and a water outlet, a first valve port and a second valve port are arranged in the valve body, a fixed iron core assembly is assembled on the upper portion of the valve body and composed of a sleeve and a fixed iron core, a hole is vertically formed in the center of the sleeve, the fixed iron core is fixed to the upper end of the sleeve, a movable iron core assembly is arranged in the sleeve, a central hole is vertically formed in the upper portion of the movable iron core assembly, a spring is assembled in the central hole, the lower end of the movable iron core assembly is matched with the first valve port, and a magnet exciting coil is arranged outside the fixed iron core assembly; a gland is assembled on the lower portion of the valve body, a hand-operated adjusting rod capable of moving vertically is arranged at the center of the gland, and the upper end of the hand-operated adjusting rod is matched with the second valve port. The dual-working-condition electromagnetic valve for the water dispenser has the advantages that the structure is simple, use is convenient, and users can choose to open the valve ports according to the number of consumers and needed water flow, so different requirements are met.

Description

technical field [0001] The invention relates to the technical field of electromagnetic valve manufacturing, in particular to a dual-working-condition electromagnetic valve for water dispensers. Background technique [0002] Some water dispensers now control the opening and closing of the water outlet by switching the faucet (mechanical type), while others control the opening and closing of the water outlet by the control button (electromagnetic type). Wherein, in the water dispenser controlled by electromagnetic, its control button is connected with an electromagnetic valve to realize the opening or closing of the water outlet. [0003] Existing electromagnetic valve is made up of excitation coil, fixed iron core, compression spring, movable iron core, valve body etc. Its working principle is that when the excitation coil is not energized, the sealing head of the fixed iron core will close the valve under the action of the compression spring and the back pressure of the val...

AI Technical Summary

Problems solved by technology

This solenoid valve has the above-mentioned defects of only two states of open and closed, and consumes a lot of power during use, and the cost of use is high, so its structure needs to be further improved.
