Abstract

The invention discloses a flow adjustable high-low conversion valve for hydraulic oil with a wide range of application. The valve comprises a valve body, a flange plate connected to the upper end of the valve body, a lower cylinder cover connected to the upper end of the flange plate, an outer cylinder body connected to the upper end of the lower cylinder cover and an upper cylinder cover connected to the upper end of the outer cylinder body; a liquid inlet channel and a liquid outlet channel are formed in the valve body; a valve seat is arranged in one side, close to the liquid inlet channel, of the valve body; a valve clack matched with the valve seat is arranged in the valve body; the upper end of the valve clack is connected to a valve rod; an inner cylinder body is slidably arranged at the lower end in the outer cylinder body; a piston is slidably arranged in the inner cylinder body; the upper end of the valve rod successively penetrating through the flange plate, the lower cylinder cover and the inner cylinder cover is connected to the piston; an adjusting disc is slidably arranged at the upper end in the outer cylinder body; and the upper end of the adjusting disc is connected to an adjusting screw.

Description

technical field [0001] The invention relates to a valve, in particular to a high-low switching valve with adjustable flow rate of hydraulic oil. Background technique [0002] Hydraulic systems are used in many fields such as petroleum, chemical industry, machinery, etc., and hydraulic oil valves are required in hydraulic systems to control the flow and cut-off of hydraulic oil. The existing hydraulic oil valve can only play the role of opening and closing, and some fields have relatively strict requirements on the hydraulic oil valve, which needs to be able to adjust the flow of hydraulic oil flowing through the hydraulic valve. The existing hydraulic oil valve cannot achieve this. Function, the function is relatively single, the scope of application is small, and it cannot well meet the diversified use needs of various fields. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-low switching valve with adjus...
