The openend of pipe is adjacent with the spring base in valve body, be provided with a spring, spring between straight tube and spring base supporting
One end with support straight tube openend fix, the other end and spring base are fixed；Protection straight tube, institute are additionally provided with spring inner
The one end for stating protection straight tube is fixed with spring base, and the other end is placed in inside support straight tube.
Further, generally one is only provided between spring base and needle seat in heating power expansion valve of the prior art
Helical spring, single helical spring is susceptible to stuck phenomenon when reciprocating under pressure, also result in for a long time
Camber of spring follows the string, and makes expansion valve cisco unity malfunction.The utility model to the spring in heating power expansion valve by tying
Structure is improved, and by increasing a protection straight tube in spring, the one end for protecting straight tube is fixed with spring base, protects the one of straight tube
It has been a supporting role that end is fixed with spring base, it is to avoid spring bending displacement, stuck phenomenon occurs.In addition, protection straight tube
The other end through support straight tube openend, be subsequently placed in support straight tube inside, while design when, it is desirable to protect straight tube not with
Support straight tube to be connected and also have a certain distance with straight tube is supported, so protection straight tube can be with the compression of spring or stretching
Move and move inside or outside straight tube toward supporting.The blind end for supporting straight tube is connected with the needle in valve body, supports straight
The blind end of pipe plays a part of needle seat.In addition, the degree of superheat of heating power expansion valve is by opening the degree of superheat and effective degree of superheat group
Into the unlatching degree of superheat is relevant with the pretightning force of spring, and effective degree of superheat is relevant with the stroke of the intensity of spring and needle, using this
The spring structure of utility model is conducive to strengthening the intensity of spring, extends the life-span of spring.
Adjusting rod is additionally provided with valve body, the adjusting rod is connected with spring base.Further, adjusting rod is by adjustment
The size of spring force is adjusting the unlatching degree of superheat of heating power expansion valve.
Also include adjusting pole socket, the regulation pole socket is threaded connection with valve body, adjusting rod is located at and adjusts inside pole socket.
Further, adjust pole socket to be threaded connection with valve body, solve valve body of the prior art with pole socket is adjusted and adopt bolt
Easily there is the problem of bolt falling in the mode of connection.
The utility model compared with prior art, has the following advantages and advantages：
1st, a kind of improved structure of the heating power expansion valve for car refrigerator of the utility model, by heating power expansion valve
Spring structure improve, by spring increase by one protection straight tube, protect straight tube one end fix with spring base, protection
One end of straight tube is fixed with spring base has been a supporting role, it is to avoid spring bending displacement, stuck phenomenon occurs, makes valve
Cisco unity malfunction, the problem for causing refrigerator normally to freeze；
2nd, a kind of improved structure of the heating power expansion valve for car refrigerator of the utility model, adjusts pole socket and passes through with valve body
Threaded connection, solves the valve body of the prior art mode with bolts with pole socket is adjusted and bolt falling easily occurs
Problem.

To make the purpose of this utility model, technical scheme and advantage become more apparent, with reference to embodiment and accompanying drawing,
The utility model is described in further detail, and exemplary embodiment of the present utility model and its explanation are only used for explaining this
Utility model, is not intended as to restriction of the present utility model.
Embodiment 1：
A kind of improved structure of heating power expansion valve for car refrigerator as shown in Figure 1, including valve body 1, in valve body 1
It is additionally provided with a semi-enclosed cylindrical support straight tube 2, the blind end for supporting straight tube 2 and the needle 3 being located in valve body 1
Connection, it is described to support the openend of straight tube 2 adjacent with the spring base 4 in valve body 1, supporting between straight tube 2 and spring base 4
Be provided with a spring 5, one end of spring 5 and support straight tube 2 openend fix, the other end and spring base 4 are fixed；In spring
Protection straight tube 6 is additionally provided with inside 5, one end of the protection straight tube 6 is fixed with spring base 4, and the other end is placed in support straight tube 2
Portion.Adjusting rod 7 is additionally provided with valve body 1, the adjusting rod 7 is connected with spring base 4.Also include adjusting pole socket 8, the regulation
Pole socket 8 is threaded connection with valve body 1, and adjusting rod 7 is located at and adjusts inside pole socket 8.
A kind of course of work of the improved structure of the heating power expansion valve for car refrigerator：One kind is by made by elastic metallic
The top of diaphragm 9 is acted on below by the pressure of evaporator outlet 10 by the pressure effect of working medium in temperature-sensitive bag with the power of spring 5.Diaphragm 9
In the presence of three power, heave up or down, so that valve opening is turned down or opens big, to the liquid supply rate for adjusting evaporimeter.
When the liquid measure into evaporimeter is less than when needing of evaporimeter thermic load, then the degree of superheat of steam increases at evaporator outlet 10,
The pressure of the top of diaphragm 9 thus forces diaphragm 9 to bloat downwards more than the pressure of lower section, by the compression spring 5 of adjusting rod 7, and
Needle 3 is backed down, valve opening is opened greatly, then liquid supply rate increase.Otherwise when liquid supply rate is more than when needing of evaporimeter thermic load, then steam
The degree of superheat for sending out steam at device outlet 10 reduces, the reduced pressure in temperature-sensitive system, and the active force of the top of diaphragm 9 is less than lower section
During active force, diaphragm 9 is bloated upwards, spring 5 extends, move and make valve opening to turn down on adjusting rod 7, the liquid supply rate to evaporimeter
Just reduce therewith.
Above-described specific embodiment, is entered to the purpose of this utility model, technical scheme and beneficial effect
One step is described in detail, be should be understood that and be the foregoing is only specific embodiment of the present utility model, is not used to limit
Fixed protection domain of the present utility model, all any modifications within spirit of the present utility model and principle, made, equivalent are replaced
Change, improve, should be included within protection domain of the present utility model.
