Description

The integrated valve group

Technical field

The utility model relates to the compressed garbage technical field, is specially a kind of integrated valve group that places in the disjunctor compression box power system.

Background technique

Domestic existing integrated valve group can not satisfy the rubbish compression working condition requirement of China, can not very little space content receive more hydraulic parts integrated, bulky, lack reliability, and maintenance is also inconvenient.

The model utility content

The technical problem that the utility model solved is to provide a kind of integrated valve group, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solved adopts following technological scheme to realize:

The integrated valve group; Comprise filler opening, return opening, solenoid valve, relief valve, hydraulic control valve, one-way valve, pressure transducer and filter; Said solenoid valve is divided into a solenoid valve, No. two solenoid valves, No. three solenoid valves, No. four solenoid valves; Include A, B, P, four mouths of T, said filler opening links to each other with No. three solenoid valve P mouths through one-way valve; The oil outlet of said filter links to each other with said return opening; The filler opening of said filter and a said solenoid valve T mouth, No. two solenoid valve T mouths, No. three solenoid valve T mouths all are connected in parallel; Said relief valve is divided into relief valve A and relief valve B; Said relief valve A is between said filler opening and solenoid valve T mouth; Said relief valve B is between the filler opening of said filter and No. three solenoid valve A mouths, and a said solenoid valve A mouth links to each other with said No. two solenoid valve A mouths, between said No. two solenoid valve A mouths and T mouth, hydraulic control valve is installed; A said solenoid valve B mouth links to each other with No. two solenoid valve B mouths; Its oil circuit links to each other with the control end of said hydraulic control valve; Said No. two solenoid valve P mouths link to each other with No. three solenoid valve B mouths; Said No. three solenoid valve A mouths link to each other with No. four solenoid valve P mouths, between said No. four solenoid valve T mouths and No. three solenoid valve T mouths an one-way valve are installed.

In the utility model, said filler opening also directly links to each other with pressure taps, and said pressure transducer is installed on its connecting passage.

Beneficial effect

The utility model meets the rubbish compression working condition requirement of China's actual conditions, and it is integrated to receive hydraulic parts in very little space content, has high reliability, and easy to maintenance.
