Description

Hydraulic manifold block

Technical field

The utility model relates to the hydraulic transmission equipment field, relates in particular to a kind of hydraulic manifold block that is used to connect various hydrovalves, element and the pipeline of hydraulic system.

Background technique

The Placement of hydrovalve is threaded, flange connects, connect plank frame.Be threaded and element dispersed placement during flange is connected, institute takes up space bigger, and pipeline is staggered, and joint is various, is not easy to the loading and unloading maintenance.Connect plank frame plate valve is fixed on above the connecting plate, oil circuit is connected with pipe with pipe joint behind plate between valve, and this connecting plate is simple, the inspection oil circuit is also more convenient, and oil pipe is many on the palette, and assembling is trouble very, and it is also bigger to take up space.

The model utility content

The purpose of the utility model is to overcome the problems referred to above, a kind of compact structure is provided, is convenient to load and unload and keep in repair, adapts to the hydraulic manifold block of different hydraulic Design requirements through selecting different blocks.

To achieve these goals, the technological scheme that the utility model adopted is: hydraulic manifold block is characterized in that: described hydraulic manifold block is eight combined structures, is combined by eight blocks; Described hydraulic manifold block and block are six face length side's bodily forms, and adjacent block connects and composes hydraulic manifold block successively through the block mating face, are provided with the oil through road in the block; Described hydraulic manifold block has three valve piece mating faces, has the hole that a plurality of valve pieces are installed on the valve piece mating face, and described hydraulic manifold block has an integrated package secondary surface.

The described valve piece of the utility model mating face is provided with the valve piece hydraulic fluid port of fuel feeding liquid turnover valve piece and the valve piece positioning hole of standing valve piece.

The described integrated package secondary surface of the utility model is provided with auxiliary hydraulic fluid port and pressure gauge connection.

The described block of the utility model mating face is provided with public oil return inlet T and public oil inlet P.

The beneficial effect that the utility model had is: the oil through road in the block of hydraulic manifold block has replaced traditional pipeline structure, the compact structure of hydraulic manifold block, and institute takes up space little, and is convenient to the assembling maintenance; Eight combined structures can be installed a plurality of valve for general use pieces, and nominal flow rate is big; Through selecting different block combinations, the oil through road in the block can change according to system's actual flow size, adapts to different hydraulic Design requirements.
