Abstract
The utility model relates to a member of a thermal expansive valve for an automobile air-conditioning system, which especially relates to a valve core component with an adjustable expansion valve, and comprises a valve core, a valve rod and a valve core rack. The utility model is characterized in that the valve rod traverses through the valve core rack; the valve rod and the valve core rack are in an interference fit. The utility model is advantageous in that the valve rod can freely move on the valve core rack, thereby the valve port opening can be raised and the adjusting precision of the expansive valve throttling can be improved.
Description
Affiliated technical field
The utility model relates to the member of a kind of automotive air-conditioning system with heating power expansion valve, and what be specifically related to is a kind of valve hole part of expansion valve.
Background technique
Expansion valve is a critical component of realizing throttling control in the automotive air-conditioning system, and it mainly is made of valve body, valve hole part, adjusting parts and power head part.Be provided with the low voltage terminal interface that refrigerant flows to the high voltage terminal interface of valve body and flow to vaporizer after overexpansion from condensator outlet on the valve body, the unit head cover is made of the valve seat of power skull, capillary tube, diaphragm, driver blade and valve body upper end, and wherein the valve seat of valve body upper end leads as guide portion.During work, the unit head cover is experienced the degree of superheat of evaporator outlet end and is made media expansion in the media cavity or contraction and act on diaphragm and produce axial force, by diaphragm axial force is passed to the drive link axial motion by driver blade again, promoting valve hole part by drive link moves near valve port, change valve port opening, with the control cold medium flux, reach the purpose of throttling control.Yet, its spool of valve hole part, valve rod and valve core frame in the existing expansion valve all weld fixedlys connected, when expansion valve assembling or drive link promoted valve hole part and move, aperture size that can not the free adjustment valve port influence precision of expansion valve throttling adjusting.
Summary of the invention
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the existing defective that exists, and provides a kind of new expansion valve adjustable valve hole part, and it has the characteristics of free adjustment valve port opening size.
The technological scheme that the utility model adopted: it comprises spool, valve rod and valve core frame.Wherein spool is fixedlyed connected by spot welding with valve rod one end.Valve rod passes valve core frame, cooperates by the close-fitting mode.For improving the close-fitting of valve rod and case, the valve rod vertical plane is provided with hackle mark.
The beneficial effects of the utility model are, by above-mentioned specific design, when spool is subjected to the high pressure of drive link promotion pressure or vaporizer pressurized gas, can promotes valve rod and on valve core frame, move, thereby improve the adjusting aperture of valve port, improve the degree of regulation of the expansion valve degree of superheat.
Description of drawings
Fig. 1 is a kind of concrete structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model structure is described further:
As shown in Figure 1, the utility model comprises spool (1), valve rod (2) and valve core frame (3).Wherein spool (1) is fixedlyed connected by spot welding with valve rod (2) one ends.Valve rod (2) passes valve core frame (3), cooperates by the close-fitting mode.For improving the close-fitting of valve rod (2) and valve core frame (3), the valve rod vertical plane is provided with hackle mark.When spool (1) was subjected to the high pressure of drive link promotion pressure or vaporizer pressurized gas, it was upward mobile at valve core frame (3) to promote valve rod (2), thereby can improve the adjusting aperture of valve port, improved the degree of regulation of the expansion valve degree of superheat.
Claims (2)
1. the adjustable valve hole part of expansion valve comprises spool, valve rod and valve core frame.It is characterized in that described valve rod passes valve core frame, cooperate by the close-fitting mode.
2. the adjustable valve hole part of expansion valve according to claim 1 is characterized in that the vertical plane of described valve rod is provided with hackle mark.
