Abstract

The utility model relates to an electromagnetic valve without a connection pipe. The present electromagnetic valve without a connection pipe has defections that the knife tools are severely worn out, the processing efficiency is extremely low and the burr can not be easily eliminated when a cavity of the valve base is processed, and thus the requirements of production in enormous quantities can not be satisfied. The utility model comprises a coil and a valve base positioned at the upper end and the lower end of a casing tube, a closing end blocked at the upper end of the casing tube and a core iron component positioned in the casing tube. The utility model is characterized in that the valve base is made by inlaying the inner part with the outer part. The valve base of the utility model adopts a split structure made by inlaying the inner part with the outer part. The abrasion of the knife tools is small, the burr can be easily eliminated and the processing efficiency is greatly enhanced.

Description

Solenoid valve with split type valve seat

Technical field

The utility model relates to the solenoid valve in the refrigeration system, and specifically a kind of nothing is taken over solenoid valve.

Background technique

Along with applying of refrigeration systems such as air-conditioning, freezing, refrigeration, solenoid valve is as the critical elements of electronic control, and its type and structure are also various day by day.At present, do not have the structure that the valve seat of taking over solenoid valve adopts integral type, technology capability is poor, it is special when material is stainless steel, when the processing valve base cavity, exist disadvantages such as tool wear is serious, work efficiency is extremely low, the difficult removal of burr, can't satisfy requirement of mass production.

The model utility content

Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, a kind of solenoid valve of split type valve seat construction is provided, under the prerequisite that guarantees the valve seat original function, add man-hour at it, reach the purpose that tool wear is little, work efficiency is high, burr easily removes.

The utility model is taked following technological scheme: the solenoid valve with split type valve seat, comprise that the coil that is positioned at the sleeve pipe upper/lower terminal and valve seat, shutoff at the end socket of sleeve pipe upper end be positioned at the core iron parts of sleeve pipe, is characterized in that described valve seat adopts inner inlaying with the outside to form.Valve seat in the utility model adopts mosaic structure, has solved existing integral type valve seat in the existing disadvantage of boring inner chamber, and tool wear is little, and burr easily removes, thus the bigger work efficiency that improves valve seat.

Described solenoid valve with split type valve seat, inner and outside riveted joint or be welded, there is a limited step both cooperation places, are used for inner spacing in externally, outer upper ends forms a flanging that cooperates with inside, in order to strengthen the inner and outside degree of reinforcing that is connected.

Described solenoid valve with split type valve seat, inner and outside interference fit or screw-thread fit form, and there is a limited step both cooperation places, are used for inner spacing in externally.

Valve seat of the present utility model is taked inner and the split-type structural that forms is inlayed in the outside, and inner and outside separate machined links together both again, and tool wear is little, and burr easily removes, the bigger work efficiency that improves valve seat.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 takes over solenoid valve for the nothing of existing integral structure.

Fig. 2 is a kind of structural representation of the present utility model.

Fig. 3 is an another kind of structural representation of the present utility model.

Embodiment

Embodiment 1

Solenoid valve as shown in Figure 2 comprises that the coil 1 that is positioned at sleeve pipe 3 upper/lower terminals and valve seat, shutoff are at the end socket 2 of sleeve pipe 3 upper ends be positioned at the core iron parts 5 of sleeve pipe 3.Described valve seat adopts the modes of riveted joint or welding to be assembled into one by inner 6 and outside 7 by limited step 9, outside 7 upper ends formation one and inner 6 flangings that cooperate 8.

Embodiment 2

Solenoid valve as shown in Figure 3 is with embodiment 1 difference: valve seat adopts the modes of interference fit or screw-thread fit to be assembled into one with outside 7 by limited step 9 by inner 6.

Claims
