Abstract

The invention provides a cartridge balance valve comprising a valve seat, a valve shell, a valve sleeve, a balance valve element, a one-way valve element, a baffle ring, a first spring, a compensatingplunger, a second spring and an overflow valve assembly. According to the cartridge balance valve, machining is easy, the overflowing area has no sudden change, the safety protection function can bequickly achieved, and the service life is long.

Description

technical field [0001] The invention relates to a valve assembly for a hydraulic device, in particular to a plug-in balance valve. Background technique [0002] In modern construction machinery, construction machinery and other mechanical equipment, a large number of lifting hydraulic circuits are used. Among them, the balance valve is the key hydraulic component that controls the work of the hydraulic cylinder in the lifting circuit. The performance of the balance valve directly affects the performance of the main engine. [0003] The existing hydraulic balance valve generally has such a shortcoming: when the load is lowered, due to the characteristics of sudden changes in the flow area of ​​the valve port of the hydraulic balance valve, it will cause low-frequency jitter and impact on the load, resulting in system instability and affecting the overall performance. The safety and reliability of the machine; and during the working process of the oil cylinder, because the bal...
