Problems solved by technology

However, due to the large switching torque of the valve in the sealed state, if the direct drive is used, the wear will become very serious, and a high-power motor is required, thereby increasing the cost
At present, the existing valve that lifts first and then changes direction has a complex structure and high cost, and is only suitable for large valves

Abstract

The invention provides a lifting and reversing four-way valve of an optimized structure and relates to a switching component for an automobile air conditioner heat pump system. The lifting and reversing four-way valve comprises a screw rod driven by the outside to rotate, a plate cover, a four-way valve core, a spring, a sealing ring and a four-way valve body. Two rotating blades for driving the valve core to rotate are arranged at the bottom of the screw rod. The four-way valve core comprises two driven bosses, two limiting blocks and a flow passageway through which fluid passes, wherein thedriven bosses are used to cooperate with the rotating blades of the screw rod to rotate the valve core. The four-way valve body is provided with two limiting bosses matched with the limiting blocks for limiting the valve core and four inlets and outlets matched with the flow passageway on the valve core to form a channel through which the fluid passes. The plate cover is fixed on the valve body and concentric with the screw rod, an open hole is formed in the bottom of the screw rod, and the screw rod can be matched with a shaft of the valve core. According to the lifting and reversing four-wayvalve of the optimized structure, the structural strength of the parts is improved after the structure is optimized, the limiting guiding design of the parts is increased, and the operation reliability of the valve member is improved.

Description

technical field [0001] The invention relates to the field of fluid machinery and air conditioning systems, in particular to a structure-optimized lift reversing four-way valve and a fluid switching method. Background technique [0002] The cooling, heating, and defrosting modes of the automotive air-conditioning heat pump system are switched through three-way and four-way reversing valves, but the existing reversing valves are prone to vibrations and structural failures during the driving of the car. , stuck or leaked. In order to better realize the reversing function of the reversing valve, a rotary four-way reversing valve can be used to realize it. The rotary four-way reversing valve is generally driven by a motor, which has high reliability. However, due to the large switching torque of the valve in the sealed state, if the direct drive is used, the wear will become very serious, and a high-power motor is required, thereby increasing the cost. At present, the existing...
