Abstract
The invention discloses a double-acting overflow valve for a hydraulic motor. The double-acting overflow valve comprises a valve seat. A valve element capable of sliding back and forth is arranged in the valve seat. An elastic pressure assembly pressing the valve element in the valve seat is arranged at one end of the valve seat. The valve seat is provided with an oil hole I and an oil hole II. An oil cavity I is formed by the lower end face of the valve element and the inner wall of the valve seat and communicates with the oil hole I through an oil pipe arranged in the valve element. A pressure releasing section is arranged on the valve element. An oil cavity II is formed by the pressure releasing section and the valve seat and communicates with the oil hole II. When the valve element moves in the valve seat, the pressure releasing section can communicate with the oil hole I and the oil hole II, a pressure bearing face is arranged on the part, at the upper portion of the oil cavity II, of the valve element, and the pressure bearing face is equal to the lower end face of the valve element in area. According to the double-acting overflow valve, minimization of the size and the installing space is achieved, the installing space and the manufacturing material cost are saved, and larger selecting space is provided for installation of other components.
Description
Technical field
The present invention relates to hydraulic test parts technical field, particularly to a kind of hydraulic motor double acting overflow valve.
Background technology
Cam-type axial piston motor is to say the device that hydraulic energy transfer is mechanical energy, main on the equipment such as engineering machinery
Complete the output of moment of torsion, it is achieved the hoofing part to engineering mechanical device, during whole, the hydraulic shock that motor produces,
By overflow valve, pressure pulse is directly decayed.Small engineering machinery equipment the installation of usual each parts when manufacturing and designing all
Compact, especially walking mechanism, existing overflow valve can not meet limited requirements of installation space.
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, takies the hydraulic pressure that installing space is little
Motor double acting overflow valve.
For achieving the above object, the present invention uses following technical proposals: a kind of hydraulic motor double acting overflow valve, including
Valve seat, the inside of described valve seat is provided with the spool that can slidably reciprocate, and one end of valve seat is provided with one and is pressed in valve seat by spool
Elastic pressure assembly, described valve seat is provided with oilhole I and oilhole II, and the lower surface of described spool and valve base inner wall form an oil pocket
I, oil pocket I is connected with oilhole I by an oil pipe being located in spool；Described spool is provided with a pressure release section, described pressure release section with
Valve seat forms oil pocket II, and oil pocket II connects with oilhole II, and when spool moves in valve seat, pressure release section can connect oilhole I and oilhole
II, the top spool of described oil pocket II sets a pressure-bearing surface, pressure-bearing surface and the area equation of spool lower surface.
Described elastic pressure assembly includes a groups of springs, screw plug and spring base, and groups of springs is located at the screw plug of valve seat end
Being pressed in valve seat, groups of springs is pressed in the upper surface of spool by spring base.
Described pressure-bearing surface area is equal to the area of spool lower surface, and is the half of spool upper surface area.Use this side
Case can make the vent pressure preset at oilhole I and oilhole II equal.
The bottom of the pressure release section of described spool is provided with a locator protrusions.
During use, when at oilhole I, oil pressure arrives setting value, the intrinsic pressure movable valve plug of trying hard to recommend of oil pocket I overcomes the pressure of groups of springs
Mobile, make oilhole I connect with oilhole II, make the hydraulic oil at oilhole I be back to motor oil back chamber by oilhole II and realize pressure release,
Pressure release completes rear spring group and is pushed back by spool in situ；When at oilhole II, oil pressure arrives setting value, the pressure in oil pocket II promotes
Spool overcomes the pressure of groups of springs to move, and makes oilhole I connect with oilhole II, and the hydraulic oil at oilhole II is back to by oilhole I
Motor oil back chamber realizes pressure release.
The invention has the beneficial effects as follows: the double acting overflow valve of the present invention realizes minimizing of volume and installing space, joint
About installing space and manufacture material cost, the installation for miscellaneous part provides bigger selection space.
