Description
Technical field
The present invention relates to engine turbine supercharging technology field, especially, relate to a kind of turbogenerator pressurized machine final controlling element pressure regulation connection valve.
Background technique
The final controlling element of turbocharger of motor is again turbocharger bypass valve actuator, is one of critical elements of pressurized machine, manages be connected with turbine box bypath valve with gas compressor air outlet.In prior art, the sleeve pipe standing part of final controlling element and attachment portion are an entirety, accurately to meet then needs dismounting to fixing and adjustment simultaneously and the integral multiple of tilt fixing (180 °) can only be rotated, the requirement accurately regulating pressure limits value cannot be reached at all.Final controlling element carries unique control section of pressurized machine and engine control machine internal air pressure limits value, if final controlling element because of air pressure limits value control inaccurate, turbosupercharger may be made to open bypath valve not yet because bearing barometric pressure, and therefore cause that body loosens, heating, leakage of oil, booster turbine rotor speed are too high causes pressurized machine burning machine; Meanwhile, engine section also can be too high because of boost pressure during high speed operation, thus the cylinder-firing pressure of motor exceed limits value after uncontrollable cause damage and cannot work.
Rotate the low pressure limits value that cannot accurately regulate of degree of regulation for prior art middle sleeve and cause the problem of turbocharger of motor job failure, not yet have effective solution at present.
Summary of the invention
Rotate the low pressure limits value that cannot accurately regulate of degree of regulation for prior art middle sleeve and cause the problem of turbocharger of motor job failure, the object of the invention is to propose a kind of turbogenerator pressurized machine final controlling element pressure regulation connection valve, rotation degree of regulation can be improved, accurate pilot pressure restriction, ensures that turbocharger of motor normally works.
Based on above-mentioned purpose, technological scheme provided by the invention is as follows:
According to an aspect of the present invention, a kind of turbogenerator pressurized machine final controlling element pressure regulation connection valve is provided.
Valve pocket is comprised according to turbogenerator pressurized machine final controlling element pressure regulation connection valve provided by the invention, valve pocket is a Coupling with groove structure, wherein, a stop nut is fixedly connected with in groove structure, freely rotate in the space that stop nut can provide in the groove structure of valve pocket, but can not relative to valve pocket translation; Valve pocket also comprises fixed hole.
Wherein, groove structure is positioned at the upper end of valve pocket, and the space in the groove structure of valve pocket is divided into two-part by stop nut, asks compared with the external space of shallow-layer and compared with space in deep layer respectively; When final controlling element is connected with final controlling element pressure regulation connection valve, final controlling element tail end inserts in the groove structure of valve pocket, wherein, final controlling element tail end is through the external space and stop nut and touch interior space, and stop nut can carry out micro-translation by External Force Acting on final controlling element tail end.
Further, physical contact is not had between the outer surface of final controlling element tail end and the groove structure interior surface of valve pocket; The outer surface of final controlling element tail end and the internal surface of stop nut have mutually corresponding male and female screw thread, are fixed between final controlling element tail end and stop nut by screw thread rotation, and stop nut can reach the effect of upward-downward translation on final controlling element tail end by the mode rotated.
Further, fixed hole is arranged at valve pocket lower end; When pressurized machine is connected with final controlling element pressure regulation connection valve, fixed hole is buckled on the bypass valve of pressurized machine, and the bypass valve of pressurized machine is vented to final controlling element by fixed hole.
As can be seen from above, technological scheme provided by the invention adjusts the technological scheme of connection valve relative to final controlling element height by using the rotation stop nut be fixed in valve pocket, no longer be limited to each adjustment and can only rotate 180 degree, therefore improve rotation degree of regulation, accomplish accurate pilot pressure restriction, and ensured that turbocharger of motor normally works.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural drawing of the turbogenerator pressurized machine final controlling element pressure regulation connection valve according to the embodiment of the present invention.
Embodiment
Clearly understand for making the object, technical solutions and advantages of the present invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technological scheme in the embodiment of the present invention carry out further clear, complete, describe in detail, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope of protection of the invention.
According to one embodiment of present invention, a kind of turbogenerator pressurized machine final controlling element pressure regulation connection valve is provided.
As shown in Fig. 1 (a), 1 (b) Yu 1 (c), valve pocket 4 is comprised according to the turbogenerator pressurized machine final controlling element pressure regulation connection valve that embodiments of the invention provide, valve pocket 4 is a Coupling with groove structure, wherein, a stop nut 2 is fixedly connected with in groove structure, freely rotate in the space that stop nut 2 can provide in the groove structure of valve pocket 4, but can not relative to valve pocket 4 translation; Valve pocket 4 also comprises fixed hole 5.
Wherein, groove structure is positioned at the upper end of valve pocket 4, and the space in the groove structure of valve pocket 4 is divided into two-part by stop nut 2, asks compared with the external space 1 of shallow-layer and compared with space in deep layer 3 respectively; When final controlling element is connected with final controlling element pressure regulation connection valve, final controlling element tail end inserts in the groove structure of valve pocket 4, wherein, final controlling element tail end touches interior space 3 through the external space 1 with stop nut 2, and stop nut 2 can carry out micro-translation by External Force Acting on final controlling element tail end.
Physical contact is not had between the outer surface of final controlling element tail end and the groove structure interior surface of valve pocket 4; Outer surface and the internal surface of stop nut 2 of final controlling element tail end have mutually corresponding male and female screw thread, fixed by screw thread rotation between final controlling element tail end and stop nut 2, stop nut 2 can reach the effect of upward-downward translation on final controlling element tail end by the mode rotated.
