Abstract
The invention discloses a ball float valve which comprises a balance weight, a shell, a ball float rod, a float ball, a valve seat, a throttling valve, a valve rod and a valve; wherein the throttling valve is arrange in the shell; the valve seat and the valve rod are respectively arranged at the two ends of the throttling valve; the valve is arranged in the valve seat; the valve rod is connected with the ball float rod; and the balance weight and the float ball are respectively arranged at the two ends of the ball float rod. The ball float valve can realize the automatic opening or closing of the valve, so that liquid level of refrigerant can be kept in a steady state value, important parts such as coils and the like are prevented from being burned out due to the long time operation of a compressor caused by too little refrigerant, noises due to too high exhaust temperature caused by insufficient refrigerant are overcome, and influence on the service life of an expansion valve due to unstable liquid level of the refrigerant is avoided.
Description
Technical field
The present invention relates to a kind of float valve.
Background technique
Short of refrigerant in the circulatory system can make that the cold of freezer is not enough, and the abnormal phenomena of short of refrigerant is that suction, exhaust pressure are all low; But delivery temperature is higher, that the expansion valve place can hear is interrupted " " airflow noise, and sound is big than usual; Refrigeration agent influences working life, if can make that also compressor turns round for a long time very little in the system; Heating causes burning out important spare parts such as winding easily, and maintenance cost is high.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of existing technology, a kind of ability automatic regulating valve door aperture size is provided, and can makes the refrigeration agent liquid level keep the float valve of steady state value.
Technological scheme: in order to realize above purpose, a kind of float valve of the present invention, it comprises equilibrium block, housing; Ball lever, ball float, valve seat, throttle valve; Valve rod and valve are provided with throttle valve in the described housing, and the two ends of described throttle valve are respectively equipped with valve seat and valve rod; Be provided with valve in the described valve seat, valve rod links to each other with ball lever, and the two ends of described ball lever are respectively equipped with equilibrium block and ball float.
The two ends of described upper shell are respectively equipped with vapor space hole and fluid space hole.
Described ball float is a Metal Ball.
Beneficial effect: a kind of float valve provided by the invention, through the needle of lever pushing throttle valve, valve just can be along with the decline or the rising of liquid level in the vaporizer; Realize opening automatically greatly perhaps and turn down; Make the liquid level of refrigeration agent keep steady state value, prevent to cause burning out important spare parts such as winding because of refrigeration agent makes that very little compressor turns round for a long time; Overcome because of lack of refrigerant makes the higher noise that produces of delivery temperature, avoid influencing the working life of expansion valve because of refrigeration agent liquid level instability.
Description of drawings
Fig. 1 is a whole-cutaway view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Be illustrated in figure 1 as a kind of float valve of the present invention, it comprises equilibrium block 1, housing 2, ball lever 3, ball float 4, valve seat 5, throttle valve 6, valve rod 7 and valve 8.
Be provided with throttle valve 6 in the described housing 2, the two ends of described throttle valve 6 are respectively equipped with valve seat 5 and valve rod 7, are provided with valve 8 in the described valve seat 5, and valve rod 7 links to each other with ball lever 3, and the two ends of described ball lever 3 are respectively equipped with equilibrium block 1 and steel ball float 4.
Two flanged (FLGD) holes up and down of housing 2 are communicated with the vapor space and the fluid space of vaporizer respectively; Described vapor space links to each other with vapor space hole 9; Described fluid space links to each other with fluid space hole 10, and like this, the float chamber has identical liquid level with vaporizer.Power in order to keying in the float valve is a steel ball float 4; When the load of vaporizer changes and heroic spirit liquid level when changing; Ball float 4 promptly goes up and down in the float chamber along with liquid level again, and ball lever 3 is through the opening and closing of valve rod 7 control throttle valve 6, therefore; The valve 8 that is provided with in the valve seat 5 can perhaps be closed along with the decline of vaporizer heavy-fluid face or the automatic unlatching that realizes valve of rising, to keep constant liquid level.
Above-mentioned embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
