Abstract
The utility model provides a thermostatic expansion valve valve body, include medium inlet, medium export and communicate the circulation chamber between medium inlet and medium export, circulation chamber upper portion is valve rod channel, the circulation intracavity sets up the bidirectional balance head piece, the bidirectional balance head piece is a horizontal channel, horizontal channel is located same horizontal plane with the medium export, thermostatic expansion valve valve body compact structure is reasonable, and is sealed remarkably productive, and the design of bidirectional balance head piece has effectively prevented in the thermostatic expansion valve use to produce undulantly because of pressure variation, has stronger market competition.
Description
Technical field
This utility model is related to the control field that throttles, especially a kind of thermal expansion valve body.
Background technology
Heating power expansion valve (Thermostatic Expansion Valve, TXV) is air-conditioning and refrigeration plant is commonly used
Throttle part, it can be throttled and blood pressure lowering to the liquid refrigerant carrying out condenser, and the temperature according to evaporator outlet
Spend and to adjust the flow of the cold-producing medium from condenser feeding vaporizer, to adapt to the needs that cooling load is continually changing.
Specifically, heating power expansion valve, by the use of the temperature change of air tank head (temperature-sensitive bag) as signal, control valve opening, changes
Variable refrigerant volume.
But generally require at this stage to use different heating power expansion valves according to different cold-producing mediums, universality is poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of thermal expansion valve body.
For solving above-mentioned technical problem, the technical solution of the utility model is：
A kind of thermal expansion valve body, including medium inlet, media outlet and be communicated in medium inlet and media outlet
Between circulation chamber, described circulation chamber top is valve stem passage, and described circulation intracavity arranges bidirectional balanced head piece, described two-way flat
Weighing apparatus head piece is a horizontal channel, and described horizontal channel is located in same level with media outlet.
Preferably, above-mentioned thermal expansion valve body, the upper outside of described valve stem passage is provided with has spacing and sealing work
Sealing gasket.
This utility model structure has the advantages that：
Above-mentioned thermal expansion valve body, rationally, sealing effectiveness projects compact conformation, and the design of bidirectional balanced head piece is effectively anti-
Stop during heating power expansion valve uses because pressure change produces fluctuation, there is the stronger market competitiveness.
Brief description
Fig. 1 is the partial structural diagram of thermal expansion valve body described in the utility model.
In figure：The bidirectional balanced head piece of 1- medium inlet 2- media outlet 3-
4- valve stem passage 5- sealing gasket
Specific embodiment
For further illustrating this utility model, now cooperation accompanying drawing is described in detail：
As shown in figure 1, a kind of thermal expansion valve body, including medium inlet 1, media outlet 2 and be communicated in medium and enter
Circulation chamber between mouth and media outlet, described circulation intracavity arranges bidirectional balanced head piece 3, and described bidirectional balanced head piece is a water
Flat passage, described horizontal channel and media outlet are located in same level, and described circulation chamber top is that valve stem passage 4 is (built-in
Valve rod), the upper outside of described valve stem passage is provided with has spacing and sealing function sealing gasket 5.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
