Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
Examples
Referring to fig. 2-3, an electronic expansion valve mounting structure includes a valve body 1 and a connecting block 2 matched with the valve body, wherein a positioning groove 11 is further provided on the valve body 1 above the vent hole 12 in this embodiment besides a conventional vent hole 12, and the positioning groove 11 is used in cooperation with the connecting block 2 to position the valve body 1 on the connecting block 2.
Specifically, the connecting block 2 is provided with a bolt hole for fixing the body of the connecting block 2. The connecting block 2 is provided with a mounting hole 24 for inserting one end of the valve body, and the connecting block 2 is provided with an air inlet end 21, an air outlet end 22 and a screw hole 23 which are communicated with the mounting hole 24. A screw 3 is arranged in the screw hole 23, and the position of the screw hole 23 corresponds to the positioning groove 11 on the valve body 1; when the valve body is mounted on the connecting block, one end of the screw 3 can prop against the positioning groove 11 to position the valve body 1 on the connecting block 2.
In this embodiment, a sealing structure is arranged on the valve body between the vent hole and the positioning groove, and the sealing structure can plug the middle section of the mounting hole, so that the gas entering from the air inlet end 21 is prevented from being discharged from the mounting hole 24. For this purpose, the structure of the mounting hole 24 and the structure of the valve body 1 are modified as follows:
The sealing structure comprises a crimping inclined surface protruding outwards on the valve body 1, and the crimping inclined surface surrounds the valve body 1 for one circle to form a crimping slope. The connection block 2 is provided with an abutment surface corresponding to the pressure-contact inclined surface, which is inclined downward toward the mounting hole 24 side. After one end of the valve body 1 is inserted into the mounting hole 24, the pressing inclined surface can be tightly attached to the abutting surface, so that a sealing state is formed between the pressing inclined surface and the abutting surface, and gas entering from the air inlet end is prevented from being discharged from the mounting hole.
Of course, in order to further improve the tightness of the electronic expansion valve after being mounted on the connecting block, a sealing ring can be placed on the valve body below the pressure welding inclined plane, and the tightness of the valve body 1 mounted on the connecting block 2 can be further improved through the use of the sealing ring.
In use, after one end of the valve body 1 is inserted into the mounting hole 24 and put in place, the screw 3 is screwed to fix the valve body 1 to the mounting block 2. The gas flows into the valve body from the inlet end 21 and then exits the outlet end 22 along the outlet of the valve body.
In the embodiment, the electronic expansion valve is mounted by adopting the mode of locking the positioning groove 11 by the screw, the original mounting of the metal connecting plate is abandoned, the electronic expansion valve is directly mounted on the connecting block and locked by the screw, and the whole firmness is strong.
The design of the positioning groove 11 in this embodiment is as follows: the whole valve body is of a circular ring structure, the valve body is surrounded in a circular shape with the same height, the cross section of the positioning groove is of an isosceles trapezoid structure, and the included angle between the two waists of the positioning groove is 60 degrees.
The positioning groove in the embodiment adopts a surrounding design, so that the electronic expansion valve is convenient to adjust the position during installation. If the positioning groove is not in a ring structure but in a hole structure (intermittent connection), the electronic expansion valve needs to consider the position adjustment of the positioning groove during installation, and the operation is inconvenient.
The application redesigns the valve body of the electronic expansion valve to have the positioning groove 11, and designs the connecting block 2 in a matching way, and the two are mounted in a matching way, so that the stability is good; and from the single-view electronic expansion valve, the structure is simplified, and the product cost is reduced.
The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
