Description
Technical field:
This utility model is hydraulic valve technical field, and the throttling in a kind of building-block machine Hydraulic Power Transmission System is unidirectional
Choke valve.
Background technology:
Current existing one-way throttle valve is to be composed in series by check valve and choke valve two parts, in hydraulic system, main
Play the effect moved reciprocatingly in building-block machine actuator.But this one-way throttle valve makes group because of the factor such as pressure, flow
Closing the lathe actuator curve that moves reciprocatingly undesirable, movement velocity is slower.In order to make the close idealization of its curve movement, from
And on the basis of one-way throttle valve one group of choke valve of superposition again, be therefore allowed to structure loaded down with trivial details, one-way throttle valve leakage, permeability probability
Increase, also increase valve group setting height(from bottom) and cost, waste resource.
Utility model content:
The purpose of this utility model is that structure is loaded down with trivial details, easily lets out for one group of choke valve of the other superposition of former one-way throttle valve
The problem of dew, and in the same valve body of former one-way throttle valve, increase by one group of choke valve, make throttling one-way throttle valve, composition
Simplify the structure, reduce leakage, permeability probability.
The technical scheme is that
A kind of throttling one-way throttle valve, including one-way throttle valve.
Technical points is:
Offering hole at one-way throttle valve body and be fixed with fittings body, fittings body open interior also threaded has throttling rod.
Throttling oil duct, throttling oil duct connection hydraulic fluid port p ＇ and one-way throttle valve external body is offered in one-way throttle valve body.
The inner termination of throttling rod is arranged in throttling oil duct.Oil mass in regulating throttling oil duct.
Throttling oil duct can include a oil duct, b oil duct, c oil duct and d oil duct, a sequentially connected
Oil duct connects with one-way throttle valve external body, and d oil duct is connected with the hydraulic fluid port p ＇ of one-way throttle valve.Throttling rod interior
Termination has tapered end face, tapered end face tip to be arranged on b oil duct
Outlet in.The direction come in face of oil.
Entrance at a oil duct is provided with inlet seal circle.
The outside being positioned at fittings body at throttling rod can be provided with clamp nut.
It is provided with the first sealing ring between fittings body and one-way throttle valve body, between throttling rod and fittings body, is provided with the second sealing
Circle.
This hydraulic valve fuel volume adjusting is in the range of 0-40L.
Have an advantage in that:
This novel throttling one-way throttle valve overcomes existing one-way throttle valve operating mode single, and movement velocity is relatively slow, and work shape
State is not ideal enough, affects work Mobile Slide stability, and cost is high, the problems such as valve quantity is many.At the same valve of former one-way throttle valve
One group of choke valve of internal increase, makes throttling one-way throttle valve, it is to avoid also additionally to fold when using former one-way throttle valve
Add one group of choke valve, so that valve composition simplifies the structure, reduce leakage, permeability probability, reduce the setting height(from bottom) of valve, save money
Source, reduces cost, makes duty curve close to idealization, and work Mobile Slide working stability, and workpiece quality improves, so that
Work efficiency increases.
Making valve group quantity reduce, cost reduces, fault rate reduces, and reliability, stability promote, and the workpiece quality of production carries
Height, makes work efficiency promote, valve group quantity reduce also be reduce ooze, leakage of oil probability, Operation and Maintenance simplification simultaneously, structure
Practical, there is certain industrial competition.

Fig. 1 is front view profile of the present utility model.
Fig. 2 is top view profile of the present utility model.
Fig. 3 is hydraulic pressure graphical diagram.
Inlet seal circle 1, throttling rod 2, fittings body the 3, first sealing ring 4, clamp nut 5, a oil duct, b oil duct, c oil duct, d
Oil duct, one-way throttle valve 6, spring 7, P meet low pressure and mass flow fuel supply chamber, P1Connect high-pressure low-flow fuel supply chamber, the second sealing ring 8.
Detailed description of the invention
A kind of throttling one-way throttle valve, including one-way throttle valve 6.
In the right side opening apertured of one-way throttle valve body and threaded have fittings body 3, fittings body 3 open interior is the most threaded
There is throttling rod 2.
Throttling oil duct is offered, a oil duct that throttling oil duct includes sequentially connecting, b oil duct, c oil duct in one-way throttle valve body
With d oil duct, a oil duct connects with one-way throttle valve external body.
The inner termination of throttling rod 2 has tapered end face, tapered end face tip to be arranged on going out of b oil duct
In mouthful.The oil mass entering c oil duct from b oil duct can be regulated.
D oil duct is connected with the hydraulic fluid port p ＇ of one-way throttle valve 6.
Entrance at a oil duct is provided with inlet seal circle 1.
The outside being positioned at fittings body 3 at throttling rod 2 is provided with clamp nut 5.
It is provided with the first sealing ring 4 between fittings body 3 and one-way throttle valve body, between throttling rod 2 and fittings body 3, is provided with second
Sealing ring 8.
This utility model increases a, b, c, d oil duct and screw thread etc. on the basis of former one-way throttle valve in same valve body, i.e.
Increase by one group of choke valve.
Therefore valve pressure oil is made up of two parts: P oil circuit fuel feeding is low pressure and mass flow pressure oil (oil circuit in unit's valve body), P1
Oil circuit fuel feeding (a oil duct, b oil duct, c oil duct and d oil duct) is high-pressure low-flow pressure oil.
When the Mobile Slide that works needs rapid movement by low pressure and mass flow and the P of P oil circuit1High-pressure low-flow pressure oil is altogether
Same fuel feeding.
When needing stable and that displacement is little high-pressure low-flow pressure oil work when the Mobile Slide that works works, this high pressure
Low discharge pressure oil is through P1Mouth, oil duct a, before oil duct b delivers to throttling rod 2, adjust flow through throttling rod 2 and (turn throttling rod 2 to adjust
Position) arrive oil duct c afterwards, then deliver to the actuator of the work Mobile Slide that hydraulic fluid port p ＇ connects through oil duct d, now due to P1Oil
The oil pressure that pressure is come higher than P chamber, so one-way throttle valve 6 is at spring 7 and P1The pressure oil come acts on lower closedown, only oil pressure jointly
The P high, flow is little1The work that the actuator of pressure oil maintenance work Mobile Slide is stable and strong.
Inlet seal circle 1 loads at valve body faying face, the second sealing ring 8 and the first sealing ring 4 be respectively charged into throttling rod 2,
In fittings body 3, throttling rod 2 loads in fittings body 3, and during then fittings body 3 loads threaded valve body, clamp nut 5 is arranged on
On the screw thread of throttling rod 2.
P ＇ hydraulic fluid port is connected to the actuator of work Mobile Slide, and P hydraulic fluid port connects big flow, the oil feeding line of low-pressure,
This fuel feeding delivers to the work Mobile Slide that p ＇ hydraulic fluid port, i.e. this hydraulic fluid port connect after check valve choke valve 6, spring 7 Accommodation such as grade
Actuator, for actuator rapid operation.
P1Hydraulic fluid port connects high-pressure low-flow oil feeding line, and this fuel feeding is through oil duct a, b, and through throttling rod 2, oil duct c, d deliver to p ＇
The actuator of the work Mobile Slide that hydraulic fluid port this hydraulic fluid port i.e. connects, for during actuator processing workpiece or for execution machine
Structure rapid operation uses.
