Abstract

The invention provides a check valve for an air conditioner. The check valve for the air conditioner comprises a valve seat and N valve body assemblies arranged on the valve seat, wherein N is larger than or equal to 2. Each valve body assembly comprises a valve body, a valve element, an air valve core, an O-shaped seal ring located in a seal ring groove of the valve element and a connecting pipe which is connected with an air inlet and an air outlet in the valve body, wherein the valve element is installed in a main hole formed in the valve body, the air valve core is installed in an auxiliary hole formed in the valve body, the main hole is sealed through a copper cap with internal threads, the auxiliary hole is sealed through a copper air valve core nut, and the air outlet is sealed through a copper nut. When the check valve, with the structure, of the air conditioner is installed, a worker just needs to conduct installation operation once, and then the demand for use of a plurality of valve bodies of the connecting pipe of an outdoor unit can be met.

Description

technical field [0001] The invention relates to the technical field of pipeline control valves, in particular to a shut-off valve used in air conditioners. Background technique [0002] Saving energy and reducing consumption, improving production efficiency and reducing production costs are one of the main topics of the current era. Nowadays, most enterprises achieve the purpose of reducing product cost and improving production efficiency through technological innovation. [0003] The household split air conditioner includes two parts, an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected by a connecting pipe. A shut-off valve used for air-conditioning installation and air-conditioning maintenance is installed and connected on the connecting pipe. Usually, the stop valve on the connecting pipe is installed on the outdoor unit by mechanical installation, and usually more than two stop valves are required to be installed on the outdoor un...
