Abstract

The invention provides a control valve. The control valve comprises a valve seat and an electromagnetic valve element component. The valve seat comprises a first valve cavity. At least part of the electromagnetic valve element component is located in the first valve cavity. The electromagnetic valve element component and the valve seat are fixedly arranged. The valve seat further comprises a firstconnector channel and a second connector channel. The first connector channel communicates with the first valve cavity. The electromagnetic valve element component can control the first connector channel and the second connector channel to be connected and disconnected. The control valve further comprises a throttling valve element component. The valve seat further comprises a second valve cavity. At least part of the throttling valve element component is located in the second valve cavity. The throttling valve element component and the valve seat are fixedly arranged. The valve seat furthercomprises a first runner. The first runner is connected with the first connector channel and the second valve cavity. The second valve cavity communicates with the second connector channel. The throttling valve element component can control the first runner and the second connector channel to be connected and disconnected and control the fluid flow. The throttling valve element component is integrated on the valve seat of the control valve, and connecting pipelines between the control valve and a throttling valve can be relatively reduced.

Description

Technical field [0001] The present invention relates to the field of fluid control technology, and more particularly to a control valve. Background technique [0002] With the development of new energy vehicles, the requirements for automotive air conditioning systems are getting higher and higher, but the heating method of traditional cars cannot be applied to new energy vehicles, while electric heating is high, affecting new energy vehicles. mileage. The heat pump system has begun to be applied to new energy vehicle air conditioners. Since the heat pump system is complicated to the traditional refrigeration system, there are many parts, how to improve the number of components of the system to reduce the pipeline between components is research direction. one. Inventive content [0003] The technical solution provides a new structure of the control valve, which uses the following technical solution: a control valve including a valve seat and a solenoid spool member including a f...
