Problems solved by technology

[0003] The pressure of the existing hydraulic valve is relatively high during use. Once the hydraulic oil enters the valve, it cannot flow back, and the hydraulic oil cannot be checked according to different hydraulic pressures, resulting in unstable opening and closing.

Abstract

The invention discloses a stably opening and closing non-return hydraulic valve which comprises an oil inlet pipe and a main oil pipe. A pressure stabilizing column is arranged at the top of the oil inlet pipe, the oil inlet pipe is communicated with the pressure stabilizing column and welded with the main oil pipe, and a pressure stabilizing oil outlet is formed in the side face of the pressure stabilizing column and communicated with the pressure stabilizing column. When hydraulic oil passes the stably opening and closing non-return hydraulic valve and when the pressure of the hydraulic oilentering the valve from the oil inlet pipe is insufficient, the hydraulic oil cannot enter the main oil pipe through an extrusion spring seat, the hydraulic oil can be stopped from returning by increasing hydraulic oil and extruding a ball at the moment, a rubber washer is arranged at an inlet, the hydraulic oil can be stabilized, oil leakage is prevented, pressure is stabilized and adjusted whenthe oil is discharged from the pressure stabilizing oil outlet of the pressure stabilizing column, and a first spring and a second spring are stressed to stably open and close the valve, so that the hydraulic oil is fed and discharged.

Description

technical field [0001] The invention relates to the technical field of return hydraulic valves, in particular to a check hydraulic valve with stable opening and closing. Background technique [0002] The hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with an electromagnetic pressure distribution valve. It can be used to remotely control the on-off of oil, gas, and water pipeline systems in hydropower stations. Clamping, control, lubrication and other oil circuits are divided into direct-acting type and pilot type, and the pilot type is mostly used. However, after research, it is found that with the continuous development and growth of my country's construction machinery, users and host units have more and more requirements for the hydraulic system of the vehicle. come higher. At the same time, high integration, tubeless and compact requirements are p...
