Embodiment Construction
[0010] The present invention will be further elaborated below in conjunction with the accompanying drawings, which are only used to explain the present invention, not to limit the present invention.
[0011] like figure 1 As shown, a combined control electric control valve mainly includes a magnetic circuit composed of a coil assembly 12, a magnetic conductor 11, a housing 15, a sheath 14, an armature 10, a terminal 100 and an air gap, as well as a bellows assembly and a valve Part, characterized in that: the valve part is divided into the main valve part I and the ball valve part II, the main valve part I is composed of the valve stem 13, the valve stem retaining ring 111, the valve stem return spring 110 and the orifice of the valve body 18, the said The valve stem 13 is sleeved with a valve stem retaining ring 111, and the two ends of the valve stem return spring 110 are respectively connected with the valve stem retaining ring 111 and the valve body 18. One end of the valv...

The invention relates to a control valve for an automotive air conditioner compressor and particularly to a composite control electric control valve. The composite control electric control valve mainly comprises a magnetic loop which is formed by an armature, an iron core, a coil assembly, a protective bush and the like, a vacuum corrugated pipe assembly, an opening corrugated pipe assembly and a valve portion. The composite control electric control valve is mainly characterized in that the valve portion is formed by a main valve portion and a ball valve portion; one corrugated pipe assembly and currents jointly control the main valve portion and the other corrugated pipe assembly control the ball valve portion to jointly control the flow of a crankshaft chamber of a compressor, so that the air conditioner utilization comfort is improved and the compressor service life is prolonged. The composite control electric control valve has the advantages of being scientific and reasonable in structural design, low in manufacturing cost, convenient to use and safe and reliable.
Description
technical field [0001] The invention belongs to the field of sensitive element control and mechanical manufacturing, and relates to a control valve for controlling a compressor, in particular to a combined control electric control valve, which is controlled by current through two types of bellows components. Background technique [0002] The existing electric control valves are mainly divided into three categories: one is switch type, which is simply controlled by current (or voltage), the valve port is closed when the current is passed, and the valve port is opened when the current is cut off; The vacuum bellows assembly senses the pressure of the suction chamber of the compressor, and the suction pressure is affected by the heat load. The heat load is high, the suction pressure is high, the heat load is low, and the suction pressure is low. The vacuum bellows component feels the suction pressure to produce contraction displacement, reduces the opening of the valve, and inc...
