Abstract
The utility model provides a guide-valve connecting structure of an electromagnetic four-way change valve, compising a bracket and a connecting frame which are fixed on a main valve and a guide valve, and the bracket and the connecting frame can be sheathed and fixedly connected. The bracket is composed of at least two symmetrical side surfaces, the upper end face of one side surface is provided with a spacing groove, and the inner surface of the corresponding connecting frame is provided with a convex surface which is cooperated with the spacing groove; The connecting frame is composed of at least two symmetrical side surfaces, and the side edge of at least one side surface of the bracket is provided with a spacing buckle which tightly buckles the side edge of the side surface of the connecting frame; thus the guide-valve connecting structure of an electromagnetic four-way change valve has the characters that the guide-valve connecting structure of an electromagnetic four-way change valve considerably improves the force state of a connecting connection point, the reliability of the connection is improved, and the useful life of the electromagnetic four-way change valve is considerably improved, etc.
Description
Technical field
The utility model relates to a kind of heat pump type air conditioner that is used for and changes refrigerant flow direction, realizes refrigeration and heats the pilot valve linkage structure of the electromagnetism four-way change-over valve of conversion purpose, belongs to a kind of valve class.
Background technique
In the prior art, the pilot valve linkage structure of heat pump-type idle call electromagnetic four-way change-over valve as shown in Figure 1, its structure mainly is made up of electromagnetic coil 11, pilot valve 12, main valve 13 three parts; Wherein weldering is shaped on shaped as frame link press span 14 on the pilot valve 12, and weldering is shaped on frame support 15 on main valve 13.Pilot valve 12 is by support 15 and link press span 14 being sleeved on, by welding or other Placement support 15 and link press span 14 being fused then, thereby pilot valve 12 is fixed on the main valve 13 with the connection of main valve 13.But owing to have neutral gear A between above-mentioned support and the link press span, so limited three degree of freedom, all the other three degree of freedoms must limit by contact, so the stress of contact is more abominable, thereby have also just reduced the reliability of this connection.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of pilot valve linkage structure of effectively utilizing support and the reliable electromagnetism four-way change-over valve that is connected of link press span is provided.But this structure comprises support and the link press span that is individually fixed on main valve and the pilot valve socket mutually and fixedlys connected, at least the support of forming by two symmetrical sides, have at least the upper-end surface of a side to offer restraining groove, and be provided with the convex surface that matches with restraining groove at the link press span inner face of correspondence.
Described link press span also is made up of the side of two symmetries at least, and the side of at least one side of support is provided with the spacing button of the link press span side side that links closely.
The upper-end surface of described support bi-side all offers restraining groove, and respectively is symmetrically arranged with the spacing button of the link press span side side that links closely on the side of support bi-side.
Described support restraining groove is interrupted face groove, and its shape can be irregular shape.
Advantage of the present utility model is that it has improved the stress of connection contact greatly, thereby has also just improved the reliability of this connection, has improved the working life of electromagnetism four-way change-over valve greatly.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 2, the utility model mainly is made up of electromagnetic coil 21, pilot valve 22, main valve 23 three parts; Wherein weldering is shaped on link press span 24 on the pilot valve 22, and weldering is shaped on support 25 on main valve 23.Fig. 3, shown in Figure 4, by the support 25 that two symmetrical sides 26 are formed, the upper-end surface of its bi-side 26 all offers restraining groove 27, and this restraining groove 27 also can be interrupted face groove, and its shape can be irregular shape; And the link press span of forming by the side 28 of two symmetries equally 24, its inner face is provided with the convex surface 29 that matches with restraining groove 27, sees Fig. 5, shown in Figure 6.On the side of support 25 bi-side 26, respectively be symmetrically arranged with the spacing button 30 of link press span 24 sides 28 sides that link closely.When being sleeved on link press span 24 on the support 25, the convex surface 29 that is periphery just is located on the restraining groove 27 of support 25, its two inner side surface 28 just button is attached on the outer side surface 26 of support, the dual-side of its side 28 is then fastened by the spacing button 30 of support 25 both sides, so linkage structure just only is left to throw off up and down this degrees of freedom, by welding or other Placement, both are connected and fixed then, the reliability of this linkage structure is improved greatly as riveted joint or screw connection.
The utility model also can be arranged on spacing button 30 on the side of link press span 24 in other embodiments, and the spacing button 30 of this moment turns over to the inside; The utility model also can be welded on support 25 on the pilot valve 22, simultaneously link press span 24 is welded on the main valve 23, and they all belong to the technological scheme that is equal to.
