Abstract

The invention discloses a hydraulic circuit controlled by a sequence valve and a limit air valve. A hydraulic oil tank and an oil pump are connected through a low-pressure oil pipe; a single multi-way valve, the oil pump and a travel valve are connected through a three-way joint and a high-pressure rubber pipe; the single multi-way valve and a pneumatic control valve are connected through a polyurethane (PU) air pipe; the single multi-way valve and double-acting hydraulic cylinders are connected through a high-pressure rubber pipe and a steel rigid pipe assembly; a two-position three-way electromagnetic valve or a two-position three-way pneumatic control valve, a hydraulic lock and a two-way throttle valve are sequentially connected in series in the circuit; the double-acting hydraulic cylinders are symmetrically distributed on two sides of a garbage transport truck box body; a single-acting hydraulic cylinder and a double multi-way valve are connected through a high-pressure rubber pipe; the sequence valve is connected in series in the circuit; and the single multi-way valve and the two-position three-way electromagnetic valve or the two-position three-way pneumatic control valve are connected with the hydraulic oil tank through a low-pressure rubber pipe respectively. The double-acting hydraulic circuit is locked automatically, and a hydraulic original is prevented from being damaged by pressure rise of the double-acting hydraulic circuit.

Description

technical field [0001] The invention belongs to hydraulic system design technology, in particular to a sequential hydraulic circuit composed of a sequence valve and a two-position three-way valve. Background technique [0002] The garbage transfer vehicle is a common type of sanitation series vehicles. It is mainly used in conjunction with the garbage compression station. It is a transportation tool for transporting the compressed garbage blocks in the garbage compression station to power plants or designated locations. [0003] With the continuous development of society, the number of municipal solid waste transfer vehicles is also greatly increasing. At present, most of the models used in the market are refitted from the second-class chassis of 4×2 or 6×4. When the garbage transfer vehicles will After the garbage blocks are transported to the designated location, sanitation workers need to operate the hydraulic system to control the opening of the rear door of the garbage ...
