Abstract

The invention provides a valve block. The valve block comprises a first sub-valve block and a second sub-valve block, the first sub-valve block is provided with a working oil opening of a hydraulic system, the second sub-valve block is provided with a control oil opening and a power oil opening of the hydraulic, the control oil opening is used for setting a control valve, the power oil opening is used for communicating a hydraulic reversing main valve of a closed type hydraulic pump or an open type hydraulic pump; wherein the first sub-valve block and the second sub-valve block are provided with main oil path channels which are matched and communicated, and the first sub-valve block and the second sub-valve block are connected in superimposition mode. The invention further discloses a pumping device. The valve block is provided with good generality, and simultaneously production process of the valve block is optimized.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a valve block and pumping equipment using the valve block. Background technique [0002] In the prior art, the valve block is all in one piece, and has a complex pipeline structure inside. [0003] At present, a large number of standard hydraulic components and pipe fittings have been used in concrete pumping equipment (such as concrete pumping trucks). There are large differences in . At present, the valve block of this targeted design has the following problems: [0004] First, the introduction of a new concrete pumping equipment product often requires a redesign of the valve block. Not only the design cycle is long, but the performance of the new valve block also needs to be assembled in the new product to go through a long period of industrial assessment. [0005] Second, the versatility and interchangeability of the valve blocks of different types of concrete pumping e...
