Embodiment Construction

[0017] The hydraulic balance valve that automatically adapts to load changes of the present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0018] Referring to FIG. 1 , the hydraulic balance valve automatically adapting to load changes includes a main valve, a load adapting valve, a control valve, a valve plate 14 and an adjusting rod 1 . The control valve is fixed on the top of the main valve with bolts, the valve plate 14 is fixed on the right side of the main valve with bolts, and the regulating rod is located at the left side of the main valve and is directly opposite to the spool 19 of the load adapting valve. The control valve includes a control valve body 6, a control valve spool 8, a spring 7 and a screw plug 5. The front and rear chambers communicate with the main oil port 1A and main oil port 2B of the main valve, and the spool is a cone. valve structure.

[0019] The main valve includes a main va...

Abstract

The present invention is a kind of hydraulic balance valve capable of adapting load change automatically, belongs to the field of hydraulic control valve technology, and aims at solving the problem of matching the balance capacity and load. The hydraulic balance valve includes one main valve, one load adapting valve and one control valve. The main valve and the control valve are cone valves, and the load adapting valve is one slide valve. The load adapting valve has four external oil ports, one valve core with serial small holes, one strong spring and one weak spring, and can raise the regulating performance of the hydraulic balance valve. The present invention has the advantages of no low frequency jitter, capacity of regulating the throttle size automatically based on load to save energy, no leakage, and easy manufacture.

Description

technical field [0001] The invention relates to a hydraulic balance valve that automatically adapts to load changes, which belongs to the category of hydraulic control valves, and relates to a balance valve for controlling various hydraulic cylinders installed vertically or obliquely in various open hydraulic circuits, especially in telescopic cylinders of cranes. Balance valve for hydraulic control. Background technique [0002] In modern construction machinery and construction machinery and equipment, a large number of hydraulic load-bearing systems are used. Among them, the balance valve is the key hydraulic component of this type of system, and its performance directly affects the performance of the whole machine. Because the valve port of the traditional hydraulic balance valve remains unchanged during the operation of the whole machine, if the load changes when the hydraulic load-bearing system is under load, it is difficult for the spool opening of the balance valve t...
