Integral type multi-way valve and working method thereof

Abstract

The invention relates to an integral type multi-way valve. The integral type multi-way valve comprises an oil inlet valve joint (1), a plurality of working valve joints (2) and an oil return valve joint (4), wherein the plurality of working valve joints (2) are arranged between the oil inlet valve joint (1) and the oil return valve joint (4); the oil inlet valve joint (1), the working valve joints (2) and the oil return valve joint (4) form an integral type structure; the oil inlet valve joint (1) is provided with an oil inlet P(7), and the oil return valve joint (4) is provided with an oil return opening T(5); and each of the plurality of working valve joints (2) is provided with two working oil openings A(6) and B(3). The integral type multi-way valve is characterized in that a hydraulic lock (8), a pressure compensation flow control valve (11) and a reversing valve rod assembly (13) are sequentially arranged in each working valve joint (2) from the top to the bottom. The integral type multi-way valve has the advantages that flow and pressure distribution is reasonable, energy is saved, emission is reduced, and the phenomena of barrel tossing, engine extinguishing and cylinder collision are effectively solved.

Description

technical field [0001] The invention relates to a multi-way valve, in particular to an integral multi-way valve. Background technique [0002] Among the many sanitation machines, the side-mounted garbage compression truck automatically dumps the garbage by lifting the garbage can through the pull rod, which can conveniently collect the garbage in the roadside garbage can into the garbage compartment, and compress the garbage into pieces through the rear compression device for transportation. One person can complete the operation, convenient, fast, high efficiency, saving labor, saving garbage volume, no secondary pollution, wide application range, and a high market penetration rate at present. [0003] The side-mounted garbage compression transport vehicle system is powered by the vehicle's own engine, and is connected to the quantitative pump through the power take-off to provide high-pressure oil source for the system. Through the multi-way valve reversing, the garbage can...

AI Technical Summary

Problems solved by technology

[0004] 1. The speed of the trash can is uncontrollable when it is lifted and dumped, and the trash can is smashed, especially when the garbage is heavy and the weather is cold;

[0005] 2. When the push shovel multi-stage oil cylinder completes the compression action and retreats, the back pressure is too high, the energy loss is large, the car is held back, and the flame is turned off in severe cases;

[0006] 3. The speed of pushing and shoveling multi-stage oil cylinders to complete the compression action and return to the last stage of small oil cylinders is too fast, resulting in the phenomenon of "cylinder collision";

[0007] 4. Hydraulic locks are installed on the pipeline, there are many leakage points, and the layout of the pipeline is increased, resulting in high cost
