Abstract

The invention discloses a quick-closing butterfly valve group device which comprises a hydraulic oil inlet, a hydraulic oil outlet and an oil return port, and further comprises a hydraulic control reversing valve connected with the hydraulic oil outlet, a pilot-operated type hydraulic control valve connected with the hydraulic control reversing valve, and an overflow valve connected with the pilot-operated type hydraulic control valve, the overflow valve is respectively connected with the hydraulic oil inlet and the oil return port, and when the pressure of the hydraulic oil inlet is in a specified range, the hydraulic control reversing valve is reversed along with reversing of the pilot-operated type hydraulic control valve. The reversing valve can work within a set pressure range and has a speed-adjustable reversing function.

Description

technical field [0001] The invention relates to the field of hydraulic control, in particular to a quick-closing butterfly valve group device. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. [0003] At present, the valve of the hydraulic cylinder cannot guarantee the normal operation of the hydraulic cylinder within the specified pressure range. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a quick-closing butterfly valve group device, which can work within a set pressure range and has a speed-adjustable reversing function. [0005] The present invention is realized through t...
