Problems solved by technology

[0002] Existing flow regulating valves generally have only one spool, and the adjustment of the flow is realized by changing the positional relationship between the spool and the valve port. The minimum flow, maximum flow and flow adjustment accuracy are fixed. When the flow requirements change It is necessary to replace the flow regulating valve, which is inconvenient to use

Abstract

The invention discloses a flow adjusting valve, a heat pump system and a control method. The flow adjusting valve comprises a valve seat. A first opening and a second opening are formed in the valve seat. The valve seat is internally provided with a main flow way and a bypass flow way which communicate with the first opening and the second opening. The valve seat is further internally provided with a first valve element used for opening and closing the main flow way and a second valve element used for opening and closing the bypass flow way. The first valve element is linked with the second valve element. The flow adjusting valve is provided with the main flow way and the bypass flow way, the flow state in the main flow way and the flow state in the bypass flow way are changed by changing the position of the first valve element and the position of the second valve element so that different flow requirements can be met, and use is convenient; and in addition, due to the fact that the first valve element and the second valve element have a linkage relation, the two valve elements can be linked only by driving one valve element, and the structure is simple.

Description

technical field [0001] The invention relates to the field of flow regulation, and more particularly relates to a flow regulating valve, a heat pump system and a control method thereof. Background technique [0002] Existing flow regulating valves generally have only one spool, and the adjustment of the flow is realized by changing the positional relationship between the spool and the valve port. The minimum flow, maximum flow and flow adjustment accuracy are fixed. When the flow requirements change The flow regulating valve needs to be replaced when necessary, which is inconvenient to use. Contents of the invention [0003] In view of this, one of the objectives of the present invention is to provide a flow regulating valve that can meet different flow requirements and is easy to use, a heat pump system with good defrosting effect and a control method thereof. [0004] In a first aspect, a flow regulating valve is provided. [0005] A flow regulating valve, comprising a ...
