The utility model has the advantages of simple structure and reasonable design, through be provided with first filter screen and second filter screen respectively in first inlet and second inlet, can filter the fluid in the inlet, prevent that tiny grit in the fluid from entering into the valve pocket in, lead to the fact wearing and tearing to case, valve rod.
Description
Technical field
This utility model relates to valve class field, particularly relates to a kind of hydraulic valve preventing oil contamination.
Background technology
Hydraulic valve is the Automation Elements of a kind of pressure oil operation, and it is by distributing valve pressure oil
Control, be generally applied in combination with electromagnetic distributing valve, can be used for distant control power station oil,
The break-make of gas and water pipe-line system.Be usually used in clamping, control, the oil circuit such as lubrication.Hydraulic valve
It is divided into direction valve, flow valve, pressure valve etc..Hydraulic valve plays the heaviest in hydraulic system
The effect wanted, any one hydraulic system, no matter it is the simplest, hydraulic pressure all can not be lacked
Valve, the hydraulic mechanical equipment of same technique purpose, by various combination and the use of hydraulic valve,
The distinct multiple hydraulic system scheme of oil channel structures can be formed, therefore hydraulic valve is hydraulic pressure
Kind and specification element general, most active most, most widely used in technology.The base of hydraulic valve
This structure mainly includes the manipulation that spool, valve body and driving spool do relative motion in valve body
Controlling organization, the version of spool has multiple, and valve body offers the valve coordinated with spool
Body opening or valve seat orifice, also external oil pipe into and out of hydraulic fluid port, the operating mechanism of spool has hands
Mode, mechanical type, electrodynamic type and hydrodynamic or electro-hydraulic dynamic formula.
During the use of hydraulic valve, fluid enters in valve pocket by inlet, due to
Fluid is mixed into tiny grit, spool can be produced and corrode, form a rule thread
Groove, thus reduce the service life of spool, affect the serviceability of hydraulic valve.
Utility model content
This utility model is in order to overcome deficiency of the prior art, it is provided that one prevents fluid
The hydraulic valve polluted.
This utility model is to be achieved through the following technical solutions:
A kind of hydraulic valve preventing oil contamination, including cylindrical valve body, along described
The direction of axis line of valve body offers valve pocket, described valve body offers the first inlet,
Two inlets, the first liquid outlet and the second liquid outlet, and described first inlet, second
Inlet, the first liquid outlet and the second liquid outlet size are identical, described first inlet and
The first drainage screen and the second drainage screen, and described first mistake it is respectively arranged with in second inlet
Filter screen and the second drainage screen all use stainless steel material to make, and thickness is identical.
