Abstract

The invention relates to an electromagnetic valve, in particular an oil stopping electromagnetic valve, and belongs to the technical field of electromagnetic valves. The electromagnetic valve comprises a block, a shell, a sealing seat, an armature, a coil component, a sheath, a cover plate, a spring and an iron core, wherein oil holes in the sealing seat are connected with an oil inlet channel and an oil outlet channel respectively, the lower end of the armature is connected with a gland, and the lower end of the gland is in contact with the oil holes of the sealing seat; the inner back part of the armature is provided with the spring, the upper end of the spring is provided with the iron core, and the upper and lower ends of the spring are in compressed contact with the iron core and the armature. The electromagnetic valve has a simple, compact and reasonable structure, can effectively control the switch of an oil circuit, and has a good sealing performance and a small current; the iron core is matched with the armature through conical surfaces, which increases the opening pressure and can reduce the required drive current.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to an oil stop electromagnetic valve, which belongs to the technical field of electromagnetic valves. Background technique [0002] The switch solenoid valve is the most commonly used valve. Wide variety of applications. It is generally composed of valve stem, valve seat, electromagnetic coil parts and so on. The oil stop solenoid valve is a kind of on-off valve, which is generally used to cut off the oil circuit to ensure the safety of the system. [0003] In the prior art, the oil stop solenoid valve generally needs a large current, and the heat generation is serious. At the same time, the sealing method of the oil stop solenoid valve generally adopts a hard seal, which requires high processing requirements for parts. Contents of the invention [0004] The purpose of the present invention is to overcome the above disadvantages, thereby providing an oil stop solenoid valve, which c...
