Problems solved by technology

[0003] Manual needle valves require manual operation, and manual hydraulic reversing valves cannot meet the needs of automated hydraulic systems; electromagnetic hydraulic reversing valves are the most common way to use hydraulic system reversing. The electromagnetic reversing valve needs a large magnetic force, which will generate a lot of heat in occasions that require frequent actions, which will affect the overall service life. The requirements for the electromagnetic switch are relatively high, the processing cost is high, and the cost performance is low.

Abstract

The invention discloses a pneumatic hydraulic three-position five-way reversing valve. The valve comprises a valve body, a pneumatic piston, a pneumatic piston plug, a ball seat, a stem, a steel ball and a center spring. By means of lateral beating and pressing in a pneumatic mode, the function of hydraulic reversing is achieved. An electromagnet does not need to be adopted in the valve body, production cost of the revering valve is effectively reduced, and meanwhile the service life is prolonged.

Description

technical field [0001] The present invention relates to hydraulic valves, and in particular provides a pneumatic hydraulic three-position five-way reversing valve controlled by compressed gas. Background technique [0002] Hydraulic directional valves are widely used in hydraulic systems. Traditional hydraulic directional valves mainly include manual hydraulic directional valves and electromagnetic hydraulic directional valves. [0003] Manual needle valves require manual operation, and manual hydraulic reversing valves cannot meet the needs of automated hydraulic systems; electromagnetic hydraulic reversing valves are the most common way to use hydraulic system reversing. The function of the direction, the electromagnetic reversing valve needs a large magnetic force, and it will generate a lot of heat in the occasion where frequent actions are required, which will affect the overall service life. The requirements for the electromagnetic switch are relatively high, the proce...
