Abstract
The invention discloses a kind of asymmetric damping valve.The present invention is in one section of cylindrical pipe, and pipeline is divided on symmetrical two parts, two-part tube wall raised two sections of different bluff bodies by the longitudinal section for crossing cylindrical center.The shape of the arbitrary cross section of every section of bluff body is all arch.The shape of the longitudinal section of bluff body is made up of circular arc and straight line, and wedge angle is formed in some places.When the fluid forward direction in hydraulic system is by this segment pipe, fluid is acted on by circular arc and wedge angle, it may occur that speed is disorderly, produces vortex, and then produce larger pressure drop.And fluid, when flowing counterflow through, fluid carries over Fluid Flow Around Blunt Body, from circular arc and the inhibition of wedge angle, and pressure drop reduces therewith.In different flow directions, flow section generation is different to shift gears and change order, so as to produce different pressure drops.The present invention is due to without movable member, so installing cooperation requires relatively low, and being difficult wear out failure.Such orifice valve then reduces cost also without driving part simultaneously, and performance is stable.
Description
Technical field
The present invention relates to a kind of hydraulic valve, more particularly to a kind of asymmetrical orifice valve.
Background technology
At present, in structure, traditional valve is by valve body, valve element（Valve seat or guiding valve）With member, the portion for driving valve element action
Part（Such as spring, electromagnet）Composition.Its action principle is all that the motion for controlling valve element changes valve port size to reach control
The purpose of fluid.But, valve core movement can accelerate the abrasion of valve element, while the failure of driving part（As spring force is not enough, electricity
Magnet damage etc.）Also the motion of valve element can be influenceed, the effect propety of valve is then influenceed.
The content of the invention
To solve the problems, such as the valve core movement of conventional valve, the present invention devises a kind of orifice valve without movable member.
The technical solution adopted by the present invention is：In one section of cylindrical pipe, pipeline is divided in the longitudinal section for crossing cylindrical center
For symmetrical two parts, raised two sections of different bluff bodies on two-part tube wall.The shape of the arbitrary cross section of every section of bluff body is all
For arch.The shape of the longitudinal section of bluff body is made up of circular arc and straight line, and wedge angle is formed in some places.When the stream in hydraulic system
When body forward direction is by this segment pipe, fluid is acted on by circular arc and wedge angle, it may occur that speed is disorderly, produces vortex, and then produce
Larger pressure drop.And fluid, when flowing counterflow through, fluid carries over Fluid Flow Around Blunt Body, from circular arc and the inhibition of wedge angle, and pressure drop is therewith
Reduce.In different flow directions, flow section generation is different to shift gears and change order, so as to produce different pressures
Drop.
The beneficial effects of the invention are as follows：The present invention is due to without movable member, so installing cooperation requires relatively low, and not
Failure easy to wear.Such orifice valve then reduces cost also without driving part simultaneously, and performance is stable.
Brief description of the drawings
Fig. 1 is the structure principle chart of the present invention（Sectional view）；
Fig. 2 is Figure 1A-A sectional view.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment：Pipe diameter is 22mm, thickness of pipe wall 5mm.Bluff body B1 circular arc A1 radiuses are 10mm, left end point and C1's
Vertical distance is 19.2, and the horizontal range of right endpoint and inner-walls of duct is 16mm；Straight line L1 inclination angle is -118 °, and length is
16.5mm；Straight line L2 length is 4.7mm, is 109 ° with straight line L1 angles；Straight line L3 length is 10.6mm, is with straight line L2 angles
103°.B2 straight line L4 inclinations angle are -126 °, and length is 6.3mm, and right endpoint and C1 vertical distance is 16mm, left end point with
The horizontal range of inner-walls of duct is 7.3mm；Straight line L5 length is 15.6mm, is 135 ° with straight line L4 angles；A2 radiuses are 11 °,
The horizontal range of left end point and inner-walls of duct is 16.5mm；Straight line L7 inclination angle is 128 °.Fluid is flowed into from valve port 1, valve port 2
Flow out for forward flow, otherwise be reverse flow.When flow flows through this orifice valve for 600L/min fluid forward direction, pressure drop is
18.5Mpa, when flowing counterflow through, pressure drop is 75Mpa.
Above-described embodiment is explanation of the invention, does not constitute and protection scope of the present invention is limited, this area skill
Art personnel are to fall into protection scope of the present invention according to conventional change that the design of the present invention is made.
Claims (2)
1. asymmetric damping valve, it is characterised in that：In one section of cylindrical pipe, pipeline is divided into by the longitudinal section for crossing cylindrical center
Raised two sections of different bluff bodies on symmetrical two parts, two-part tube wall；The shape of the longitudinal section of bluff body is by circular arc and straight line
Constitute, wedge angle is formed in some places；When the fluid forward direction in hydraulic system is by this segment pipe, fluid is by circular arc and wedge angle
Inhibition, it is disorderly to occur speed, produces vortex, and then produce larger pressure drop；And fluid, when flowing counterflow through, fluid carries over blunt
Body flows, and from circular arc and the inhibition of wedge angle, pressure drop reduces therewith.
2. asymmetric damping valve according to claim 1, it is characterised in that：The arbitrary cross section of every section of described bluff body
Shape is all arch.
