Abstract

The utility model relates to the technical field of control valves, in particular to a solenoid valve which comprises a solenoid valve cover. A hollow coil framework is arranged in the solenoid valve cover, and a coil assembly is disposed on the lower portion of the hollow coil framework in winding mode. A magnetic core is arranged in the hollow coil framework, and the upper end of the magnetic core extends out of the hollow coil framework. A magnetic core sleeve is disposed at the upper end of the magnetic core in covering mode. An annular groove is arranged at the upper end of the hollow coil framework, and a clamping sheet is clamped inside the annular groove. A spring is disposed between the annular groove and the clamping sheet. By aid of a reasonable arrangement of the solenoid valve cover, the hollow coil framework, the coil assembly, the magnetic core, the magnetic core sleeve and the clamping sheet, the purposes that the size of the solenoid valve is reduced, installation is convenient, and cost is lowered are achieved.

Description

Solenoid valve

Technical field

The utility model relates to the control valve technical field, especially relates to solenoid valve.

Background technique

At present, be provided with the hermetic cavity body in the existing solenoid valve, offer through hole in different positions, different oil pipes is all led in each hole; Be provided with valve in the middle of the cavity, both sides are provided with electromagnet, the magnet coil energising of a certain side; Valve body will attracted to that side, block or spill different oil drainage holes through moving of control valve body, and oil inlet hole is often opened; Hydraulic oil will get into different oil exit pipes, promotes in-oil cylinder piston through pressure then, and piston drives the mechanical device motion again.Just controlled mechanical motion through the control current of electromagnet like this.

But the solenoid valve of the type in use, owing to save installing space and size, so need the boundary dimension of valve be controlled in the claimed range, can exist volume big like this, and the installation time is long, and product structure is complicated, the problem that cost is high.

The model utility content

To the deficiency that above-mentioned existing technology exists, the purpose of the utility model provides solenoid valve, and it has can dwindle solenoid valve volume and easy for installation, the characteristics that reduce cost.

To achieve these goals, the technological scheme that the utility model adopted is: solenoid valve comprises the electromagnetism valve bonnet; Be provided with the hollow line ring framework in the said electromagnetism valve bonnet; Said hollow line ring framework bottom is arranged with coil groups, is provided with magnetic core in the said hollow line ring framework, and the hollow line ring framework is extended in the upper end of said magnetic core; Said magnetic core upper end is covered with the magnetic core cover; Said hollow line ring framework upper end offers annular groove, is connected with card in the said annular groove, is provided with spring between said annular groove and the said card.

Wherein, said hollow line ring framework peripheral hardware is useful on the magazine of said coil groups of restriction and said magnetic core cover position.

After adopting said structure, the utility model is compared the advantage that is had with existing technology and is: the utility model comprises the electromagnetism valve bonnet, is provided with the hollow line ring framework in the said electromagnetism valve bonnet; Said hollow line ring framework bottom is arranged with coil groups; Be provided with magnetic core in the said hollow line ring framework, the hollow line ring framework is extended in the upper end of said magnetic core, and said magnetic core upper end is covered with the magnetic core cover; Said hollow line ring framework upper end offers annular groove; Be connected with card in the said annular groove, be provided with spring between said annular groove and the said card, the utility model is through the reasonable setting of said electromagnetism valve bonnet, hollow line ring framework, coil groups, magnetic core, magnetic core cover and card; Reach and dwindle solenoid valve volume and easy for installation, the purpose that reduces cost.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the utility model.

Among the figure: 1, electromagnetism valve bonnet; 2, hollow line ring framework;

3, coil groups; 4, annular groove;

5, card; 6, magnetic core cover;

7, magazine.

Embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

As shown in Figure 1: solenoid valve, comprise electromagnetism valve bonnet 1, be provided with hollow line ring framework 2 in the said electromagnetism valve bonnet 1; Said hollow line ring framework 2 bottoms are arranged with coil groups 3; Be provided with magnetic core in the said hollow line ring framework 2, hollow line ring framework 2 is extended in the upper end of said magnetic core, and said magnetic core upper end is covered with magnetic core cover 6; Said hollow line ring framework 2 upper ends offer annular groove 4; Be connected with card 5 in the said annular groove 4, be provided with spring between said annular groove 4 and the said card 5, the utility model is through the reasonable setting of said electromagnetism valve bonnet 1, hollow line ring framework 2, coil groups 3, magnetic core, magnetic core cover 6 and card 5; Reach and dwindle solenoid valve volume and easy for installation, the purpose that reduces cost.

In the present embodiment, said hollow line ring framework 2 peripheral hardwares are useful on the magazine 7 that restriction said coil groups 3 and said magnetic core overlap 6 positions, and said magazine 7 can play a protective role to said coil groups 3 and magnetic core cover 6.

The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
