Embodiment Construction

[0018] Hereinafter, the substantial features and advantages of the present invention will be further described with reference to examples, but the present invention is not limited to the listed embodiments.

[0019] like Figure 1 to Figure 6 As shown, the slow opening and closing electro-hydraulic reversing valve 100 in this embodiment includes a main valve 1 and a solenoid valve 2 , and the solenoid valve 2 communicates with the main valve 1 . The slow-opening and closing electro-hydraulic reversing valve 100 further includes two flow stabilizers 4 and a flow valve 3, and the two flow stabilizers are a first flow stabilizer 401 and a second flow stabilizer 402 respectively. The flow stabilizer is a bidirectional flow stabilizer. The first flow stabilizer 401 is respectively communicated with the first end 11 of the main valve 1 and the first oil port A1 of the solenoid valve 2, and the second flow stabilizer 402 is respectively connected with the second end 12 of the main v...

Abstract

The invention relates to a slowly open-close electro-hydraulic directional valve. The slowly open-close electro-hydraulic directional valve comprises a main valve and an electromagnetic valve. The electromagnetic valve communicates with the main valve. The slowly open-close electro-hydraulic directional valve further comprises two flow stabilizers and a flow valve. The two flow stabilizers are a first flow stabilizer and a second flow stabilizer respectively. The first flow stabilizer communicates with a first end part of the main valve and a first oil port of the electromagnetic valve. The second flow stabilizer communicates with a second end part of the main valve and a second oil port of the electromagnetic valve. The flow valve communicates with an oil inlet of the main valve and an oil inlet of the electromagnetic valve. The slowly open-close electro-hydraulic directional valve has following beneficial effects: the slowly open-close electro-hydraulic directional valve is capable of slowing starting and stopping; the valve is adjustable in time, high in precision, good in reliability, convenient in usage and maintenance, high in standardized level, little in hydraulic impact and marked in buffer effect.

Description

technical field [0001] The invention relates to an electro-hydraulic reversing valve, in particular to a slow-opening and closing electro-hydraulic reversing valve. Background technique [0002] In recent years, hydraulic technology has been widely used in various industries, and the electro-hydraulic directional valve plays a crucial role as a control element in the hydraulic system. At present, the electro-hydraulic reversing valve produced in China has relatively simple control methods and functions, does not have adjustable opening and closing time, and has a large hydraulic impact during reversing. In the hydraulic speed control system of the shipbuilding industry and other industries, especially in special environments, the hydraulic motor speed can be increased from slow start to rated speed, and slowly decreased from rated speed to stop. The utility model relates to a slow-opening and closing electro-hydraulic reversing valve which can be started and stopped slowly,...
