Problems solved by technology

However, during the working process of the compression box, because the response time of the solenoid valve is very short, generally around 40-50ms, during its frequent closing and opening, it brings a lot of hydraulic shock to the system, seriously affecting the system and The reliability and service life of its components also bring noise pollution to the working environment; at the same time, because it uses more solenoid valves, it greatly increases the production and processing of the system valve block, the difficulty of system debugging and maintenance, and affects the production of products. Processing efficiency

Embodiment 1

[0028] Reference attached figure 1 , the integrated multi-way valve for garbage compression control of the present invention includes overflow valves 11, 12, two-position three-way solenoid valves 21, 22, 23, 24, hydraulic lock assembly 3, pressure reducing valve 4, and turning motion control assembly 5. The shovel motion control assembly 6 and P, A1, B1, A2, B2, oil ports; the overflow valve 11 communicates with the P, T oil ports to control the safety pressure of the system; the overflow valve 12 is in The overturning movement controls the oil circuit, which limits the maximum load of the dumping bucket of the garbage compression box; the overturning movement control component 5 realizes the function of a 3-position 6-way hydraulic control reversing valve, and the first solenoid valve 21 and the second solenoid valve 22 respectively obtain In the case of electric power, the function of turning up and down the dumping bucket of the compression box is realized, and combined wi...

Embodiment 2

[0030] Reference attached figure 2 , the integrated multi-way valve for garbage compression control of the present invention, the overflow valve 1, the solenoid valve 2, the hydraulic lock assembly 3, the pressure reducing valve 4, the turning motion control assembly 5, and the shovel motion control assembly 6 are all integrated in the In an integrally cast valve body. The overturn motion control assembly 5 mainly includes A end cover 51, A return spring 52, A spring seat 53, overturn valve stem 54 and seals. This assembly cooperates with the cast valve body to form P1, P2, A1, B1, T-shaped Cavity, and spring control chamber a1, b1, wherein the spring control chamber communicates with the first solenoid valve 21, the second solenoid valve 22 working port, the flip valve stem 54 is in the first solenoid valve 21, the second solenoid valve 22 and the return spring Under the joint action, there are three stations, left, middle and right, corresponding to three cavity connection...

Embodiment 3

[0033]On the basis of Embodiment 2, buffer throttles and pressure equalization grooves are provided on the valve stems of the turning motion control assembly 5 and the push blade motion control assembly 6, so as to reduce the pressure shock neutralization during the reversing process and the reversing resistance; This form of electro-hydraulic pilot control greatly prolongs the reversing time and pressure drop gradient during the reversing process with the throttling and buffering of the main valve core opening, and greatly reduces the hydraulic shock during the reversing process. . The hydraulic lock assembly includes two hydraulically controlled check valves 31 and hydraulically controlled reversing valve rods 32, which are controlled in conjunction with the turning motion control assembly 5 to realize that the tipping bucket can stop at any point. Because the hydraulically controlled check valve 31 It is an integral cone valve structure, which can achieve zero leakage, ther...

Abstract

The invention relates to an integral multi-way valve for garbage compression control. The integral multi-way valve comprises a cast valve body; two overflow valves, a pressure-reducing valve, four cartridge solenoid valves, a turnover motion control component, a shovel pushing motion control component and a hydraulic lock component are arranged in the casting valve body. The integral multi-way valve is characterized in that the cast valve body is integrally cast and formed, is provide with a valve hole and a valve chamber, and is also provided with an oil inlet, four oil outlets and an oil return port, namely P, A1, B1, A2, B2 and T respectively; the overflow valve is communicated with the oil inlet P and the oil return port T to control the safe working pressure of a system; an oil inlet of the pressure-reducing valve is communicated with the oil inlet P, and the oil outlets are connected to the four cartridge solenoid valves so as to provide pilot control power for turnover and shovel pushing motions; the four cartridge solenoid valves are respectively arranged at the two ends of the turnover motion control component and the shovel pushing motion control component and are communicated with a pilot control oil way after pressure reduction. According to the integral multi-way valve provided by the invention, the impact of the garbage compression system is reduced, and the product performances and the production and processing efficiencies are improved.

Description

technical field [0001] The invention relates to an integral multi-way valve, in particular to an integral multi-way valve for garbage compression control. Background technique [0002] Municipal solid waste treatment technology and complete sets of equipment are currently the high-tech industries that the country is focusing on developing. Urban sanitation machinery and equipment revolve around the three aspects of garbage collection, clearing, and treatment, and are moving towards environmental protection, multi-functionality, humanization, and modularization. , The direction of digital intelligence continues to develop and move forward. In the garbage, the current domestic garbage accounts for the largest part, but the domestic garbage is relatively fluffy, so it occupies a relatively large area, and the garbage is compressed and compacted through the garbage compression box, which can reduce the number of garbage trucks. It avoids the pollution caused by the fluffy garba...
