Abstract
The utility model discloses a kind of integral multitandem valve oil-feed oil duct, comprise one-time formed valve body (1), valve body is provided with the oil duct (4) with oil-feed oil duct (2) and fuel-displaced oil duct (3), near oil-feed oil duct and the valve body being positioned at described oil duct the same side is provided with the first control spool groove (6) and the second control spool groove (7), and at described first control spool groove, the first control spool (5) is installed, control in spool groove, to install second second and control spool (8).This device adopts oil-feed oil duct to be positioned at the oil duct arrangement controlled above spool, makes fluid not need, through controlling spool, therefore to avoid compression shock, thus reduce the pressure loss.Further, due to very low in the loss of each oil circuit pressure, more oil circuit can be arranged, ensure that the pressure of each oil circuit is substantially identical simultaneously.In addition, this apparatus structure is simple, strong adaptability, and sealing is reliable.
Description
Technical field
The utility model relates to a kind of multi-way valve oil-feed oil duct, and specifically a kind of integral multitandem valve oil-feed oil duct, belongs to multi-way valve field.
Background technique
Along with hydraulic system is green and the development of power-saving technology, control unit integral multitandem valve important in hydraulic system is used widely.Generally speaking, integral multitandem valve is for sheet-type multi-way valve, and integral multitandem valve refers to that all oil circuits are all arranged on same valve body, has compact structure and the advantage such as leakage rate is low.In order to reduce its size and weight, the oil duct of integral multitandem valve inside is arranged closely.At present, conventional oil input channel is all through the control spool of selector valve, and when high pressure oil is through out-of-date, will inevitably occur turbulent phenomenon owing to impacting, the friction between aggravation molecule, causes oil temperature to rise, and increases the pressure loss, thus causes energy loss to increase.
Disclose a kind of valve body oil channel structures of waist type oil duct in prior art, the oil return oil duct of this device on valve body is waist type oil duct, is processed with waist type sealed groove at the junction plane periphery place of waist type oil duct.But this device is to the reduction pressure loss and prevent temperature rise from not acting on.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of integral multitandem valve oil-feed oil duct, can avoid compression shock, reduces the pressure loss, prevents oil temperature from raising.
For achieving the above object, the technical solution adopted in the utility model is: a kind of integral multitandem valve oil-feed oil duct, comprise one-time formed valve body, valve body is provided with the oil duct with oil-feed oil duct and fuel-displaced oil duct, near oil-feed oil duct and the valve body being positioned at described oil duct the same side is provided with the first control spool groove and second controls spool groove, and at described first control spool groove, the first control spool is installed, control in spool groove, to install second second and control spool.
Further, described first control spool groove and the second control spool groove all communicate with described oil duct.
Further, described first control spool is fixedly mounted in described first control spool groove;
Further, described second control spool is fixedly mounted in described second control spool groove.
The beneficial effects of the utility model are: this device adopts oil-feed oil duct to be positioned at the oil duct arrangement controlled above spool, make fluid not need, through controlling spool, therefore to avoid compression shock, thus reduce the pressure loss.Further, due to very low in the loss of each oil circuit pressure, more oil circuit can be arranged, ensure that the pressure of each oil circuit is substantially identical simultaneously.In addition, this apparatus structure is simple, strong adaptability, and sealing is reliable.

In figure: 1, valve body, 2, oil-feed oil duct, 3, fuel-displaced oil duct, 4, oil duct, 5, first controls spool, and 6, first controls spool groove, and 7, second controls spool groove, and 8, second controls spool.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1: a kind of integral multitandem valve oil-feed oil duct, comprise one-time formed valve body 1, valve body 1 is provided with the oil duct 4 with oil-feed oil duct 2 and fuel-displaced oil duct 3, near oil-feed oil duct 2 and the valve body 1 being positioned at described oil duct 4 the same side is provided with the first control spool groove 6 and second controls spool groove 7, and at described first control spool groove 6, first control spool 5 is installed, control in spool groove 7, to install second second and control spool 8.Described first control spool groove 6 and the second control spool groove 7 all communicate with described oil duct 4.Described first controls spool 5 is fixedly mounted in described first control spool groove 6; Described second controls spool 8 is fixedly mounted in described second control spool groove 7.Two control spools and are positioned at the same side of oil duct, and the mode that oil duct is arranged is oil-feed oil duct 2 is positioned at the top that two control spools, and i when ensure that fluid flows in oil duct, does not directly stop the motion of fluid, reduces the pressure loss.
Working principle: fluid enters from the oil-feed oil duct 2 of valve body 1, the movement locus of fluid can flow along oil duct 4, spool groove 7 is controlled owing to being provided with the first control spool groove 6 and second on the valve body 1 near oil-feed oil duct 2, and at the first control spool groove 6 internal fixtion, the first control spool 5 is installed, control spool groove 7 internal fixtion second and second control spool 8 is installed, two control spool groove 6 and all communicate with oil duct 4, when fluid moves in oil duct, directly can't impact the first control spool 5 and second and control spool 8, ensure that the temperature of fluid in oil duct 4, and reduce the pressure loss.
