Abstract
The utility model discloses a solenoid valve which comprises a valve needle, an armature, a coil and a valve body. The armature is arranged on the outer side of the valve needle. The coil is arranged on the outer side of the armature. The valve body is arranged on one side of the armature. An expansion valve of the solenoid valve adsorbs the armature by means of electromagnetic force, the armature drives the valve needle to ascend to achieve opening and closing of a valve, effects of disconnecting of a liquid supply pipeline and connecting of the liquid supply pipeline are achieved, refrigerant flow adjusting stability of the expansion valve is guaranteed, and meanwhile the solenoid valve is simple in structure, and stable and reliable in working.
Description
Technical field
The utility model relates to a kind of magnetic valve.
Background technology
In refrigeration system, in order to absorb the heat of cryogenic object, the pressure of cold-producing medium saturated liquid must be dropped to below saturation pressure corresponding to the saturation temperature lower than cryogenic object, heating power expansion valve is the critical piece of formed automobile air-conditioning refrigeration system, be installed in the evaporator inlet place, it has the function of reducing pressure by regulating flow, but because expansion valve is a restricting element, itself can't close tight, thereby need to utilize solenoid valve shuts feed flow loop.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, to provide a kind of simple in structure, the magnetic valve of dependable performance.
Technical scheme: in order to realize above purpose, a kind of magnetic valve described in the utility model, it comprises needle, armature, coil and valve body, the outside of described needle is provided with armature, and the outside of armature is provided with coil, and a side of armature is provided with valve body.
Described valve body is provided with valve.
The two ends of described valve body are respectively equipped with input channel and output channel.
Beneficial effect: a kind of electromagnetic expanding valve that the utility model provides, by relying on electromagnetic attracting force armature, armature drives needle and rises, and has realized the opening and closing of valve, has reached the effect of cutting off feed liquid pipeline and connecting feed liquid pipeline; Guaranteed the stability of expansion valve adjusting refrigerant flow rate, and this electromagnetic valve structure is simple, working stability is reliable.
Description of drawings
Fig. 1 is cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
Be illustrated in figure 1 as a kind of magnetic valve described in the utility model, it comprises needle 1, armature 2, coil 3 and valve body 4.
The outside of described needle 1 is provided with armature 2, and the outside of armature 2 is provided with coil 3, and a side of armature 2 is provided with valve body 4, and described valve body 4 is provided with valve 5, and the two ends of described valve body 4 are respectively equipped with input channel 6 and output channel 7.
After coil 3 energisings, produce magnetic field, armature 2 is mentioned, drive needle 1 Open valve 5, at this moment, working media enters from input channel 6, and through valve 5, then flows out from output channel 7.When cutting off electric current, magnetic force disappears, and armature 2 and needle 1 fall under action of gravitation automatically, valve-off 5, thus cut off liquid feeding channel.
This electromagnetic expanding valve is by relying on electromagnetic attracting force armature, and armature drives needle and rises, and has realized the opening and closing of valve, has reached the effect of cutting off feed liquid pipeline and connecting feed liquid pipeline; Guaranteed the stability of expansion valve adjusting refrigerant flow rate, and this electromagnetic valve structure is simple, working stability is reliable.
The above-mentioned specific embodiment only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
