Abstract

The invention discloses a cartridge valve for hydraulic oil cylinder testing. The cartridge valve comprises a vertically distributed cartridge valve body and two positioning-mounting seats symmetrically installed in the middle of the cartridge valve body, wherein two sealing-mounting seats are symmetrically distributed the upper ends and the lower ends of the positioning-mounting seats, and sealing shells are fixed to the outer ends of the sealing-mounting seats; the middles of the positioning-mounting seats are respectively provided with elastic parts and sliding clamp-connecting parts from inside to outside. By adopting the scientific and reasonable structural design, ingenious improvement can be performed based on a traditional cartridge valve structure, the cartridge valve is effectively sealed and protected before and after use of the cartridge valve, blockage caused by foreign matter is avoided, the service life of the cartridge valve is prolonged, and the cartridge valve has a good practical and promotional value.

Description

technical field [0001] The invention belongs to the field of cartridge valves, in particular to a cartridge valve used for hydraulic cylinder testing. Background technique [0002] The cartridge valve assembly is composed of a valve core, a valve sleeve, a spring and a sealing ring, and is divided into a directional valve assembly, a pressure valve assembly and a flow valve assembly according to different uses. In the production process, the cartridge valve is often used in the test of the hydraulic cylinder, but the cartridge valve needs to be effectively sealed before and after use to prevent foreign matter from entering and causing blockage, which will affect the test. Contents of the invention [0003] The object of the present invention is to provide, specifically realize through the following technical solutions: [0004] A cartridge valve for hydraulic cylinder testing, including a vertically distributed cartridge valve body and two positioning mounting seats symme...
