Abstract
The invention belongs to technical field of hydraulic pressure, are related to a kind of rotating jet deflection harden structure, are mainly used in electrohydraulic servo valve hydraulic amplifier.Rotating jet deflection harden structure of the present invention includes the rotary deflecting plates for being provided with " V " type water conservancy diversion window, is provided with a jet stream conduit and two symmetrical jet stream disks for receiving conduit, rotary deflecting plates is at jet stream disk centre position, the Jetstream fluid of jet stream conduit receives conduit by two and equably receives, and is received in conduit at two and forms equal pressure；By rotating rotary deflecting plates, the receptor area of jet stream disk one end is set to increase, the receptor area of the other end reduces, and to make one end receive the pressure rise in conduit, the other end receives conduit internal pressure power and reduces, and forms control pressure difference.The configuration of the present invention is simple, good manufacturability, hydraulic-driven power is big, contamination resistance is strong, reliability is high.
Description
Technical field
The invention belongs to technical field of hydraulic pressure, are related to a kind of jet deflection harden structure that can export control pressure difference.
Background technology
The hydraulic amplifier used in world today's electrohydraulic servo valve is Dual Injector Baffle structure hydraulic amplifier and deflection
Jet pipe type hydraulic amplifier.Gap in Dual Injector Baffle structure hydraulic amplifier between nozzle flapper is smaller (0.04mm),
It is more demanding to oil cleanliness, often cause failure because oil contamination blocks in line；Deflected jet tubular liquid
Press complicated amplifier processing technology, debugging difficulty, production efficiency not high；Especially in electro-hydraulic pressure servo, Dual Injector Baffle
Baffle cantilever beam structure similar with the jet pipe in deflected jet tubular type hydraulic amplifier in structure hydraulic amplifier, in high temperature
Zero bias are easy to happen when with low temperature, are also easy to cause to shake.
Invention content
The purpose of the present invention：The rotating jet deflection harden structure that a kind of reliability is high, easy to process is provided.
Technical scheme of the present invention：A kind of jet deflection harden structure, it is characterized in that：Jet stream disk 1 is provided with jet stream conduit 3 and connects
By conduit 4, in jet stream conduit 3 and receives 4 intersection of conduit and be provided with circular hole, rotary deflecting plates 2 is installed, rotatably in circular hole
Deflecting plates 2 and the circular hole clearance fit are provided with water conservancy diversion window on rotary deflecting plates 2.
The conduit 4 that receives is two and is centrosymmetric.
The jet stream conduit 3 is one, and is arranged on the extending direction for receiving 4 line of symmetry of conduit.
Beneficial effects of the present invention：Rotating jet deflecting plates of the present invention is simple in structure, good manufacturability, hydraulic-driven power are big,
Contamination resistance is strong, reliability is high.
Description of the drawings
Fig. 1 is schematic structural view of the invention,
In figure：1 it is jet stream disk, 2 be rotary deflecting plates, 3 be jet stream conduit, 4 is to receive conduit.
Specific implementation mode
The present invention will be further described in detail below in conjunction with the accompanying drawings：
Referring to Fig. 1, rotating jet deflection harden structure of the present invention includes being provided with the rotary deflecting plates of " V " type water conservancy diversion window
2, a jet stream conduit 3 and two symmetrical jet stream disks 1 for receiving conduit 4 are provided with.Wherein, rotary deflecting plates 2 is mounted on and penetrates
In flow table 1, rotary deflecting plates 2 can in jet stream disk 1 left-right rotation.
When rotary deflecting plates 2 is rotated in jet stream 1 centre position of disk, the Jetstream fluid of jet stream conduit is by two receiving slits
Road equably receives, and jet stream disk 1 or so receives conduit 4 and receives identical Jetstream fluid, at two receive conduit in formed it is equal
Pressure.
By rotating rotary deflecting plates, the receptor area of jet stream disk one end can be made to increase, the receptor area of the other end subtracts
Small, to make one end receive the pressure rise in conduit, the other end receives conduit internal pressure power and reduces, and forms control pressure difference.Work as rotation
For 2 plates of rotatable deflection to when anticlockwise in jet stream disk 1, the left Jetstream fluid for receiving conduit receiving of jet stream disk 1 is more than right dump tank
The Jetstream fluid that road receives so that jet rotary may be implemented.When rotary 2 plates of deflection in the jet stream disk 1 to when right rotation, feelings
Condition is similar.Therefore rotating jet deflecting plates of the present invention is simple in structure, good manufacturability, hydraulic-driven power is big, contamination resistance is strong, can
By property height.
