Problems solved by technology

[0018] Aiming at the deficiencies of the prior art, the present invention provides a rotary electromagnetic four-way reversing valve and an air conditioner using the reversing valve, which solves the problem that the existing four-way valve needs to increase the size of the valve body and other parts due to the increase in capacity; Replacing the sliding block with a rotating disc simplifies the structure and reduces the volume of the main valve body, saving materials and reducing costs

Abstract

The invention relates to the field of fluid direction switching control devices, in particular to a rotating type electromagnetic four-way reversing valve. A rotating plate replaces a sliding block to control the flow direction of refrigerant of a D connecting pipe, an E connecting pipe, an S connecting pipe and a C connecting pipe of the four-way valve, and then switching between refrigerating circulation and heating circulation is achieved. If nominal refrigerating amount is increased, only a main valve body needs to be slightly increased, a piston part and a valve body matched with the piston part do not need to be changed, and therefore materials are saved and cost is reduced.

Description

technical field [0001] The present invention relates to a four-way reversing valve, which can be applied to, for example, an air conditioner, in particular, to a rotary electromagnetic four-way reversing valve. Background technique [0002] It is well known in the industry that the four-way reversing valve is suitable for a wide range of industries and other fields, such as: heat pump units, hydraulic servo control systems, plumbing equipment, etc. [0003] The four-way reversing valve is also one of the essential components in the air conditioner. Today, China is a top country, with its major local factories and joint ventures manufacturing a large number of SRACs and SPACs to meet the growing domestic market and export needs. The change from the first-generation grille panel to the second-generation grille panel of Chinese household air conditioner products is an improvement in the appearance of household air conditioner products. This progress is not only reflected in th...
