Description
Technical field
The utility model belongs to hydraulic balance system, particularly relates to a kind of parallel tubes pressure balance valve for oil line pipe.
Background technique
Oil line pipe is as a part for hydraulic balance system, for keeping the moment in hydraulic system to be full of by fluid, eliminate all bubbles in hydraulic system, and the danger of galling can be reduced, the efficiency of hydraulic system is increased greatly, but also more and more higher for the requirement of the equilibrated valve between oil line pipe.The complex structure cost of existing equilibrated valve is high, and the impact of the extraneous factor such as easily to be jolted, and easily occurs to carry out to fluid pressure the defect that accurately controls.Between the oil line pipe caused for pitch etc., the unexpected increase of flow or unstable change, by parallel tubes pressure balance valve, effectively can improve stability and the working efficiency of hydraulic system.
Summary of the invention
The purpose of this utility model is the deficiency for existing oil circuit oil liquid pressure equilibrium valve, provides a kind of accurate pressure compensation flap for oil line pipe.
Parallel tubes pressure balance valve for oil line pipe comprises left side oil pipe, left oil pocket, spring, valve body, spool, dextrad oil circuit, left-hand oil circuit, right oil pocket, right side oil pipe, retaining post; Left oil pocket left end is provided with left side oil pipe, left oil pocket right-hand member is connected with valve body left end, valve body right-hand member is connected with right oil pocket left end, right oil pocket right-hand member is connected with right side oil pipe, and in left oil pocket, left side and the interior right side of right oil pocket are respectively provided with 2 retaining posts, are provided with spool in valve body, valve body and spool are combined closely by precision surface, be provided with spring in left oil pocket, both ends of the spring is connected with spool left end with on the left of left oil pocket respectively, is provided with dextrad oil circuit, left-hand oil circuit in spool.
The utility model carries out instant accurately control to oil mass in oil line pipe when can there is pressure difference between oil line pipe, particularly can prevent from causing due to unstable environmental factors such as oil line pipe pitch the two between the instability of changes in flow rate, improve accuracy and the stability of oil line pipe.
