Description

Technical Field

[0001] This utility model belongs to the field of valve disassembly and assembly, and particularly relates to a disassembly and assembly device for a filter head bypass valve. Background Technology

[0002] The bypass valve used for filter heads has a valve cavity located in a deep position, making it difficult to install and remove the valve core assembly. During installation or removal, the valve core with the valve spring sleeve needs to be pressed into the valve cavity through the valve cavity mounting hole, and then the valve sleeve needs to be screwed into or out of the valve cavity mounting hole. This makes installation and removal difficult and inefficient.

[0003] Therefore, it is necessary to provide a device for disassembling and assembling the filter head bypass valve. Utility Model Content

[0008] Preferably, the top surface of the valve sleeve is provided with a positioning groove, and the bottom surface of the hexagonal nut is provided with a positioning protrusion that matches the positioning groove. The positioning protrusion engages with the positioning groove to achieve connection, while simultaneously causing the valve sleeve to rotate with the hexagonal nut.
