Embodiment
Below in conjunction with the elaboration that Fig. 4 carries out specifically to technological scheme provided by the invention.
The embodiment of the present invention provides a kind of integrated valve block, comprises pipe fitting 3 and support panel 4; Pipe fitting 3 forms fluid course, and pipe fitting 3 is fixed on support panel 4.
From to adopt a block of metal block to be processed to form integrated valve block in prior art different, the integrated valve block that the embodiment of the present invention adopts, pipe fitting 3 is adopted to form fluid course, and pipe fitting 3 is fixed on support panel 4, integrally formed integrated valve block, quality is very light, and light-weighted hydraulic integrated valve block is convenient to assembling and maintenance.
See Fig. 4, fluid course comprises first flow 38 and the second runner 39; First flow 38 comprises at least one pipe fitting 3, and through and fixing between each pipe fitting 3, first flow 38 has two openings.If form the pipe fitting more than 3 of first flow 38, the diameter of each pipe fitting 3 can be identical or different.Second runner 39 comprises at least two pipe fittings 3, and through and fixing between each pipe fitting 3, and the second runner 39 has at least three openings.
See Fig. 4, in an optional embodiment, support panel 4 comprises the first plate face 42, plate face 41, second, the 3rd plate face 43, the 4th plate face 44.
Pipe fitting 3 all adopts seamless steel pipe, and seamless steel pipe 31,34 forms first flow 38, and this runner has opening A, C.Seamless steel pipe 32,33,35,36 forms the second runner 39, and this runner has opening B, D, E, F.
The integrated valve block of technique scheme, under the hydraulic pressure runner of identical latus rectum, by same seamless steel pipe bending and molding, can reduce the local losses of pipeline like this, thus reduces the pressure loss of integrated valve block entirety.
From the above, fluid course can be divided into following two kinds of situations, and one only has two hydraulic fluid ports, and another kind has multiple hydraulic fluid port.What Fig. 4 upper left was illustrated is the situation that fluid course only has two hydraulic fluid ports, i.e. first flow 38; What bottom right was illustrated is the situation having multiple hydraulic fluid port, i.e. the second runner 39.
The quantity of first flow 38 and the second runner 39 depends on actual demand, the parts that on first flow 38, the setting position of two openings also will connect according to reality are determined, in the present embodiment, first flow 38 is set to bending runner, its opening A is positioned on the first plate face 41, and open C is positioned on the 3rd plate face 43.On second runner 39, the setting position of each opening is also that the parts that will connect according to reality are determined, in the present embodiment, the second runner 39 connects as a whole to adopt four pipe fitting 3 welding, but is not limited thereto.The opening B of the second runner 39 is positioned at the first plate face 41, and opening D is positioned at the 3rd plate face 43, and opening E is positioned at the second plate face 42, and the plate face at opening F place does not mark.In Fig. 4, opening is not established in the 4th plate face 44
The fluid flow area of first flow 38 and the second runner 39 can be equal or not etc., can select the pipe fitting 3 of different thicknesses as required.The thickness of first flow 38 and the respective included each pipe fitting 3 of the second runner 39 may be the same or different.That is, first flow 38 and the second runner 39 can be reducing runner.
Specifically following Placement is adopted: pipe fitting 3 is positioned at the framework that support panel 4 is formed, and support panel 4 is provided with the hydraulic fluid port corresponding with the opening of fluid course, and the opening of fluid course is concordant with the hydraulic fluid port corresponding to it between pipe fitting 3 and support panel 4.Namely Fig. 4 split shed A ~ F is concordant with the hydraulic fluid port on the plate face at its place.Aforesaid way defines plate valve, and so-called plate valve refers to that the hydraulic fluid port of connecting tube is not be directly arranged on valve body, but is located on base plate, and valve body can be fastened on base plate by bolt.
In the present embodiment, the material of support panel 4 is hot rolling steel plate.
For installation precision and the position degree of control integration valve block, Boring is carried out to support panel 4.Seamless steel pipe is undertaken bending, welding by the parts drawing of pipe fitting.Carrying out flaw detection and kerosene permeability test are carried out to the pipe fitting weld seam of each welding.By piping arrangement, support panel 4 and corresponding pipe fitting 3 are assembled, welded.Finally fine finishing is carried out to reach required planeness and degree of finish to the outer surface of integrated valve block.Finally, integrated valve block is suppressed and pressurize test, detect weldquality.
In order to strengthen rigidity, the protection weld seam of integrated valve block, in the space between support panel 4 inwall and pipe fitting 3 outer wall, be cast with lightweight material.Filling casting is carried out to integrated valve block inside, reduces the weight of integrated valve block, select the material that proportion is little.
In order to prevent integrated valve panel and pipeline oxidation, antirust treatment can be carried out to integrated valve block surface.Light-weighted hydraulic integrated valve block combines machinery, welding, type cavity mould, the design being cast into one, technological method.
Below in conjunction with Fig. 4, introduction detailed is further done to the integrated valve block that technique scheme provides.
Lightweight hydraulic integrated valve block basic scheme of the present invention: by the metal framework of Plate Welding, by using the steel pipe related subgroup of different tube diameters, runner needed for constructing system hydrovalve, then fix each hydraulic pipe line at frame inner wall casting lightweight material, strengthen integrated valve block integral rigidity.
As shown in Figure 4, this integrated valve block is built into the metal framework of valve block by 6 plate faces, the material selection hot rolling steel plate in plate face; By hydraulic principle G-Design piping arrangement, connect the hydraulic fluid port of each valve plate with cold rolling seamless steel, seamless steel pipe 31,32,33,34,35,36 constructs corresponding oil duct.
The light-weighted integrated valve block that technique scheme provides, this integrated valve block not only has that compact structure, volume are little, maintenance easy accessibility, and has lightweight, the little feature of flow resistance.Further, hydraulic pressure runner is simple, without the need to the auxiliary hole of the unnecessary complexity of machining, can simplify the structure of hydraulic integrated valve block, and can reduce the leakage of oil point of integrated valve block, reduces the pressure loss in hydraulic system.
The embodiment of the present invention also provides a kind of integrated valve group, and comprise the integrated valve block that hydrovalve and the arbitrary technological scheme of the present invention provide, integrated valve block is located at by hydrovalve.
The embodiment of the present invention provides again a kind of hydraulic system, comprises the integrated valve group that the arbitrary technological scheme of the present invention provides.
Technique scheme, can improve the engineering machinery applying above-mentioned hydraulic system, the energy saving of such as full Terrain Cranes hydraulic system, assembling capacity and maintenance.
