Abstract
The invention provides an oil duct crossing and connecting structure of a hydraulic multi-channel reversing valve. The connecting structure is as follows: an R-shaped circular corner is arranged at the crossing part among inner oil ducts of the valve, or at the crossing part of inner oil ducts and the oil ducts among plates. According to the invention, a straight type corner connecting structure existing at the crossing of the existing hydraulic multi-channel reversing valve oil duct is changed, commencing from the means of adding oils for the oil duct, so that the arrangement of the R-shaped circular corner at the crossing of the hydraulic multi-channel oil duct is realized, thus the problem that the R-shaped circular corner can not be arranged at the crossing of the hydraulic multi-channel oil duct in the industry for a long time is solved, the turbulent flow phenomenon at the crossing of the valve oil duct is relieved greatly, through test and examination, the oil temperature of the hydraulic system is lowered obviously, and the power consumption is reduced.
Description
Technical field
The present invention relates to hydrovalve, be specifically related to the hydraulic multichannel conversion valve oil duct and pass through commissure access node structure.
Background technique
Hydrovalve is one of significant components of hydraulic equipment.And that hydraulic multichannel conversion valve is wherein used in hydrokinetic machine is very general.The ZS of hydraulic multichannel conversion valve and DL series valve body are formed by stacking by a plurality of valve blocks, in the single valve block, are provided with asphalt channel between internal oil channel and valve block.Each asphalt channel of valve body is by internal oil channel and internal oil channel, or asphalt channel precisely is formed by connecting between internal oil channel and sheet, guarantees with this that oil duct inner fluid does not have and leaks.At present, the milling process that the processing technology of oil channel hole all adopts is traditional, workpiece blank leaves big machining allowance, oil channel hole has lost the R shape circle turning of workpiece blank state mostly after bore expanding cutting, oil duct each other pass through the Placement that friendship has become straight shape turning fully.Though this does not influence the accurate connection of asphalt channel, according to principle of hydrodynamics, when high-voltage oil liquid is flowed through straight shape corner, turbulent phenomenon will inevitably appear.Measure big turbulent flow and aggravated the intermolecular friction of fluid, caused bringing the more power loss because of oil liquid temperature in the hydraulic system constantly raises.More than the problem of Cun Zaiing also is the practical problem that does not have good plan to solve in the industry for a long time.
Summary of the invention
The invention provides a kind of hydraulic multichannel conversion valve oil duct and pass through commissure access node structure, purpose is by changing the linkage structure that oil duct passes through friendship place, to reduce the generation that oil duct passes through the turbulent phenomenon of friendship place.
Technical solution of the present invention:
The alleged hydraulic multichannel conversion valve oil duct of the present invention passes through commissure access node structure, is internal oil channel and internal oil channel at valve, or friendship place of passing through of asphalt channel is provided with R shape circle turning between internal oil channel and sheet.
Beneficial effect of the present invention
The present invention has changed the linkage structure that existing hydraulic multichannel conversion valve oil duct passes through the straight shape turning of friendship, from the means of oil channel hole processing are set about, realized that passing through friendship place at the hydraulic multichannel conversion valve oil duct is provided with R shape circle turning, solved for a long time and can't pass through the problem that friendship place is provided with R shape circle turning at asphalt channel in the industry, the asphalt channel that has alleviated valve greatly passes through the turbulent phenomenon of friendship place.After testing, the oily temperature of hydraulic system has had obvious reduction.
Description of drawings
Accompanying drawing 1 passes through the schematic representation of commissure access node structure for prior art hydraulic multichannel conversion valve oil duct;
Accompanying drawing 2 be accompanying drawing 1 A-A to the schematic representation of structure;
Accompanying drawing 3 passes through the schematic representation of commissure access node structure for hydraulic multichannel conversion valve oil duct of the present invention;
Accompanying drawing 4 be accompanying drawing 3 A-A to the schematic representation of structure.
Embodiment
As shown in Figure 1, 2
The A oil duct 2 of prior art hydraulic multichannel conversion valve 1 is the turbulent phenomenon 4 of performance with the linkage structure that friendship place is straight shape turning of passing through of B oil duct 3, the stain of joint or the aggregate of line.
Shown in Fig. 3,4,
The A oil duct 2 of hydraulic multichannel conversion valve 1 is provided with R shape circle turning linkage structure 5 with the Jiao Chu that passes through of B oil duct 3, and this structure has leading role to the mobile of fluid, thereby the oily temperature rising problem that turbulent phenomenon causes seldom can take place.
The present invention is that the claimant adopts the micro-cutting processing technology of self having grasped, place valve block to oil channel hole carries out precision casting, the surplus of the cutting of each oil channel hole is reduced to the minimum value that satisfies the micro-cutting requirement, promptly leave machining allowance greater than oil duct aperture design code size 0.6-0.7mm; Bore the micro-cutting processing of expanding each oil channel hole again.Owing to be the micro-cutting amount, thereby friendship place of passing through in each oil channel hole all remains with R shape circle turning.
Claims (1)
1. the hydraulic multichannel conversion valve oil duct passes through commissure access node structure, it is characterized in that: the internal oil channel of described valve and internal oil channel, or friendship place of passing through of asphalt channel is provided with R shape circle turning between internal oil channel and sheet.
