Abstract

The utility model provides a solenoid valve. The electromagnetic valve comprises a magnetism isolating component, a stainless steel valve cover, a compression spring, a movable iron core, a torsion spring, a diaphragm component and a valve seat from top to bottom in sequence, wherein the magnetism isolating component is welded at the top of the stainless steel valve cover, the top of the movable iron core is provided with an insertion hole, the compression spring is inserted into the insertion hole, the top of the compression spring is positioned outside the movable iron core, the top of the valve seat is provided with an opening, the compression spring, the movable iron core, the torsion spring and the diaphragm component are sequentially arranged in the opening of the valve seat, the stainless steel valve cover seals the opening at the top of the valve seat through bolts, after the structure is adopted, the structure of the electromagnetic valve is simpler, and meanwhile, the magnetism isolating component and the stainless steel valve cover are welded by using a rivet welding technology to form a connected magnetism isolating component valve cover, so that the phenomena of looseness, fracture, gas leakage and the like cannot occur on the, the potential safety hazard is also reduced.

Description

Electromagnetic valve

Technical Field

The utility model relates to a solenoid valve.

Background

The electromagnetic valve is a component controlled by electromagnetism, is an automatic basic element for controlling a switch, generally uses liquid and gas as media, can be matched with different circuits to realize expected control, and has the working principle that an electromagnetic coil generates electromagnetic force, overcomes spring force to lift a movable iron core from a valve seat, the valve is opened, when power is off, the electromagnetic force disappears, the spring presses the movable iron core on the valve seat, the valve is closed, the existing electromagnetic valve is generally a universal component, however, the existing electromagnetic valve has a complex structure, for example, a battery valve disclosed in Chinese patent publication No. CN207848539U, the electromagnetic valve with the complex structure is inconvenient to produce and assemble.

SUMMERY OF THE UTILITY MODEL

In view of the defect that current solenoid valve exists, the utility model aims to solve the technical problem that: the electromagnetic valve is simple in structure, high in service performance and long in service life.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a solenoid valve, comprising: disk seat and stainless steel valve bonnet, disk seat open-top is inside hollow, is equipped with the diaphragm subassembly in the disk seat, and the diaphragm subassembly top is movable iron core, and open the top surface of movable iron core has the spliced eye, and a compression spring is put in the spliced eye, and partial compression spring is in the movable iron core outside, movable iron core with be equipped with the torsional spring between the diaphragm subassembly, the stainless steel valve bonnet covers at the disk seat top to come to fix stainless steel valve bonnet and disk seat through the bolt, make the stainless steel valve seat can extrude compression spring, the stainless steel valve bonnet top still welds and has the magnetism subassembly that separates.

Compared with the prior art, the utility model has the advantages of: overall structure is more simple, utilizes rivet welding technique welding back with magnetism isolating component and stainless steel valve bonnet simultaneously, can improve life and security performance greatly, prevents that magnetism isolating component and stainless steel valve bonnet from appearing not hard up, the fracture, phenomenons such as gas leakage.

In the drawings:

fig. 1 is a schematic view of a solenoid valve component according to the present invention.

Description of reference numerals: 1. a valve seat; 2. a stainless steel valve cover; 3. a diaphragm assembly; 4. a movable iron core; 5. a compression spring; 6. a torsion spring; 7. a magnetic isolation component.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "bottom", "top", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1

Referring to fig. 1, the electromagnetic valve provided in this embodiment includes, from top to bottom, a magnetic isolation assembly 7, a stainless steel valve cover 2, a compression spring 5, a movable iron core 4, a torsion spring 6, a diaphragm assembly 3, and a valve seat 1, where the magnetic isolation assembly 7 is welded to the top of the stainless steel valve cover 2, an insertion hole is formed in the top of the movable iron core 4, the compression spring 5 is inserted into the insertion hole, the top of the compression spring 5 is located outside the movable iron core 4, the top of the valve seat 1 is open, the compression spring 5, the movable iron core 4, the torsion spring 6, and the diaphragm assembly 3 are sequentially placed in the opening of the valve seat 7, and the stainless steel valve cover 2 closes the top opening of the valve seat 7 through a bolt, so that the compression spring 5, the movable iron core 4, the buffer spring.

After adopting above-mentioned structure, the structure of solenoid valve is more simple, separates magnetism subassembly and stainless steel valve cover rivet welding back simultaneously, makes the solenoid valve pass through open valve more than 1000 ten thousand and assaults back and separate magnetism subassembly and stainless steel valve cover can not appear not hard up, the fracture, phenomenons such as gas leakage, has promoted life greatly, has also reduced the potential safety hazard.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various changes and modifications may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
