Abstract
The invention provides a kind of thermal expansion valve body, including medium inlet, media outlet and the circulation chamber being communicated between medium inlet and media outlet, the circulation chamber top is valve stem passage, the circulation intracavitary sets bidirectional balanced head piece, the bidirectional balanced head piece is a horizontal channel, and the horizontal channel is located in same level with media outlet；The heating power expansion valve valve body structure compact and reasonable, sealing effectiveness protrude, and the design of bidirectional balanced head piece effectively prevent during heating power expansion valve use because pressure change produces fluctuation, have the stronger market competitiveness.
Description
Technical field
The present invention relates to throttling control field, especially a kind of thermal expansion valve body.
Background technology
Heating power expansion valve (Thermostatic Expansion Valve, TXV) is that air-conditioning and refrigeration plant generally use
Throttle part, it can be throttled and be depressured to the liquid refrigerant for carrying out condenser, and according to the temperature of evaporator outlet
Spend to adjust the flow for the refrigerant that evaporator is sent into from condenser, to adapt to the continually changing needs of cooling load.
Specifically, heating power expansion valve control valve opening, is changed by the use of the temperature change of air tank head (temperature-sensitive bag) as signal
Variable refrigerant volume.
But generally require to use different heating power expansion valves according to different refrigerants at this stage, universality is poor.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of thermal expansion valve body.
In order to solve the above technical problems, the technical scheme is that：
A kind of thermal expansion valve body, including medium inlet, media outlet and it is communicated in medium inlet and media outlet
Between circulation chamber, the circulation chamber top is valve stem passage, and the circulation intracavitary sets bidirectional balanced head piece, described two-way flat
Weighing apparatus head piece is a horizontal channel, and the horizontal channel is located in same level with media outlet.
Preferably, above-mentioned thermal expansion valve body, the upper outside of the valve stem passage is provided with, and there is spacing and sealing to make
Sealing gasket.
Structure of the present invention has the advantages that：
Above-mentioned thermal expansion valve body, compact-sized rationally sealing effectiveness protrudes, and the design of bidirectional balanced head piece is effectively anti-
Stop during heating power expansion valve use because pressure change produces fluctuation, there is the stronger market competitiveness.
Brief description of the drawings
Fig. 1 is the partial structural diagram of thermal expansion valve body of the present invention.
In figure：The bidirectional balanced head pieces of 1- medium inlets 2- media outlets 3-
4- valve stem passage 5- sealing gaskets
Embodiment
To further illustrate the present invention, now accompanying drawing is coordinated to be described in detail：
As shown in figure 1, a kind of thermal expansion valve body, including medium inlet 1, media outlet 2 and it is communicated in medium and enters
Circulation chamber between mouth and media outlet, the circulation intracavitary set bidirectional balanced head piece 3, and the bidirectional balanced head piece is a water
Flat passage, the horizontal channel are located in same level with media outlet, and the circulation chamber top is that valve stem passage 4 is (built-in
Valve rod), the upper outside of the valve stem passage, which is provided with, has the spacing and sealing gasket of sealing function 5.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
