Abstract
The invention provides a kind of heating power expansion valve; including temperature-sensitive bag, air tank head, valve body, overheat spring and protective cap; the temperature-sensitive bag is connected by capillary with air tank head; the valve body is arranged at below air tank head; the overheat spring is arranged at valve inner; the protective cap is arranged at body base, it is characterised in that：The valve body includes 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 is compact-sized rationally, sealing effectiveness protrudes, the design of bidirectional balanced head piece fluctuates during effectively prevent heating power expansion valve use because pressure change produces, the design of thrust pad effectively prevents from occurring during stem movement stuck, and the design of sealing gasket serves good sealing effectiveness.
Description
Technical field
The present invention relates to throttling control field, especially a kind of heating power expansion valve.
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 heating power expansion valve.
In order to solve the above technical problems, the technical scheme is that：
A kind of heating power expansion valve, including temperature-sensitive bag, air tank head, valve body, overheat spring and protective cap, the temperature-sensitive bag pass through
Capillary is connected with air tank head, and the valve body is arranged at below air tank head, and the overheat spring is arranged at valve inner, the guarantor
Helmet is arranged at body base, and the valve body includes medium inlet, media outlet and 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 heating power expansion valve, the valve stem passage top are provided with ring-type thrust pad.
Preferably, above-mentioned heating power expansion valve, the upper outside of the valve stem passage are provided with spacing and sealing function
Sealing gasket.
Structure of the present invention has the advantages that：
Above-mentioned heating power expansion valve, compact-sized rationally sealing effectiveness protrudes, and the design of bidirectional balanced head piece effectively prevent
Because pressure change produces fluctuation during heating power expansion valve use, the design of thrust pad effectively prevents from occurring during stem movement
Stuck, the design of sealing gasket serves good sealing effectiveness, has the stronger market competitiveness.

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 heating power expansion valve, including temperature-sensitive bag 1, air tank head 3, valve body, overheat spring 9 and protective cap 8,
The temperature-sensitive bag is connected by capillary with air tank head, and the valve body is arranged at below air tank head, and the overheat spring is arranged at
Valve inner, the protective cap are arranged at body base, and the valve body includes medium inlet 6, media outlet 7 and is communicated in Jie
Circulation chamber between matter entrance and media outlet, the circulation chamber top are valve stem passage (built-in valve rod), the circulation intracavitary
Bidirectional balanced head piece 5 is set, and the bidirectional balanced head piece is a horizontal channel, and the horizontal channel is with media outlet positioned at same
On horizontal plane, be provided with ring-type thrust pad 2 at the top of the valve stem passage, the upper outside of the valve stem passage be provided with have it is spacing with
The sealing gasket 4 of sealing function.
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.
