The restricting orifice using on diesel engine is at present fixing bore, cannot regulate, and in the time not meeting the required value of corresponding operating mode, just need to change the restricting orifice of different size, uses very inconvenient.
Model utility content
The purpose of this utility model is to overcome the deficiency of existing restricting orifice, a kind of adjustable restriction orifice is provided, is arranged on diesel engine oil-way pipeline, its hole size is adjustable, can be convenient and effectively regulate lubricant oil enter machine pressure, to meet the working condition requirement of relevant diesel engine.
For achieving the above object, technical solution of the present utility model is as follows:
A kind of adjustable restriction orifice, be installed on oil line pipe, it comprises body, be connected in adjusting screw on this body and in order to lock two locking nuts of this adjusting screw, described body be provided with some mounting holes, in order to the oil circuit through hole by oil body and with the guide hole of this oil circuit through hole vertical connection, described adjusting screw is connected in this guide hole, and slide to regulate the cross-sectional sizes of described oil circuit through hole along described guide hole, described two locking nuts are screwed in this adjusting screw side by side.
The epimere of described guide hole is internal thread part, and the epimere of described adjusting screw is the external thread part screwing with this internal thread part, and the hypomere of this adjusting screw is the guide pillar part of joining with described guide hole hypomere cunning.
Described guide pillar part is provided with annular groove, in this annular groove, is equipped with seal ring.
Described seal ring is O RunddichtringO.
Compared with existing restricting orifice, the beneficial effects of the utility model are:
1, the cross-sectional sizes of the change of the slip in guide hole oil circuit through hole by adjusting screw, thereby realize adjustableization of restricting orifice, can control the pressure, flow of the fluid of the pipeline of flowing through with the requirement of adaptation condition, and without the restricting orifice of changing different size.
2, the utlity model has that flow adjustment range is large, flow-pressure reduction change level and smooth, internal leakage is little, the advantage of reliable operation and stable performance.
3, the utility model simple structure, manufacture and maintenance cost are cheap.

Embodiment
Adjustable restriction orifice described in the utility model improves on the maintenance former effective basis of restricting orifice, makes adjustableization of through hole of restricting orifice.When the factor such as hydrodynamic pressure, flow changes, and while not meeting the required value of corresponding operating mode, the regulatory function carrying by adjustable restriction orifice, change asphalt channel sectional area, in certain degree, pressure, the flow of pipeline fluid of making to flow through maintains its desirable level, and without the restricting orifice of changing again different size.
Below in conjunction with the drawings and specific embodiments, adjustable restriction orifice described in the utility model is described in further detail, but should limit protection domain of the present utility model with this.
The present embodiment is example for the adjustable restriction orifice of Wa Xilan FLEX type diesel pressure booster lubricating oil oil inlet pipe.Refer to Fig. 1 and Fig. 2, diagram adjustable restriction orifice is installed on oil line pipe, enters machine pressure for what effectively regulate pressurized machine lubricant oil.Described adjustable restriction orifice comprises body 001, adjusting screw 002, two locking nuts 003 and seal ring 004, and described adjusting screw 002 is connected on this body 001, and described two locking nuts 003 are in order to lock this adjusting screw 002.
Refer to Fig. 3 and Fig. 4, described body 001 is provided with 4 mounting holes 104, oil circuit through hole 101 and guide hole 102; Body 001 described in described oil circuit through hole 101 lateral direction penetratings, in order to pass through oil body; Described guide hole 102 is communicated with this oil circuit through hole 101 and is vertical, and the epimere of this guide hole 102 is internal thread part 103, and hypomere is unthreaded hole.
Refer to Fig. 5, the epimere of described adjusting screw 002 is the external thread part 202 screwing with the internal thread part 103 of described guide hole 102, the hypomere of this adjusting screw 002 is the guide pillar part 201 being slidably matched with described guide hole 102 hypomere unthreaded holes, this guide pillar part 201 is provided with annular groove 203, described seal ring 004 is embedded in this annular groove 203, the gap of fluid between adjusting screw 002 and body 001, leak avoiding, sealing circle 004 can be O RunddichtringO; Described adjusting screw 002 screws in described guide hole 102, in the time of rotation adjusting screw 002, described guide pillar part 201 slides along the unthreaded hole of described guide hole 102 hypomeres, change and shelter from part oil circuit through hole 101, thereby regulate the cross-sectional sizes of described oil circuit through hole 101, to change flow and the pressure of oil circuit.
