Abstract
The invention discloses a gas solenoid valve capable of positively riveting. The gas solenoid valve comprises a coil assembly (10), a movable iron core (12) and an integrated bracket (16), wherein theintegrated bracket (16) comprises a fixed iron core (18) and a bracket (17); the fixed iron core (18) and the bracket (17) are integrally formed; the fixed iron core (18) comprises a planar part (181), a tapered surface part (182) and a guide part (183); a height H1 from the planar part (181) to the bottom side of the bracket (17) is 5-15 mm; a height H2 of a guide part 3 is 3-13 mm; and a taperdimension alpha of the tapered surface part 2 is 11-52 degrees. The gas solenoid valve capable of positively riveting provided by the invention has the biggest advantage that the integrated design ofthe fixed iron ore bracket is remarkably improved in processing period, precision, cost, efficiency, quality and the like in comparison with a split structure design.
Description
technical field [0001] The invention relates to a gas solenoid valve, in particular to a forward riveted gas solenoid valve. Background technique [0002] As an important component of household gas appliances, gas solenoid valve plays a vital role in realizing the functions of household gas appliances. With the continuous improvement of market demand, technical issues such as reducing costs, improving efficiency, and enhancing quality need to be solved urgently. [0003] The static iron core and the sealing plate of the existing positive riveted gas solenoid valve are split structures, that is, the static iron core is produced by machining, and the bracket is produced by stamping, and the static iron core and the bracket are riveted and matched. However, the main disadvantages of this process are: [0004] The processing procedure of the static iron core is cumbersome, the processing cycle is long, the processing accuracy is low and the processing cost is high; [0005] T...
