Description

Non-pneumatic type mechanical control device

Technical field

The utility model relates to turbomachinery field, particularly relates to a kind of non-pneumatic type mechanical control device.

Background technique

Existing diesel turbosupercharger exhaust gas by-pass valve is the controller control of being opened or being closed by exhaust gas by-pass valve, the main diaphragm type structure that adopts, in controller inside, there is one deck elastomer diaphragm, diaphragm and controller top cover form an airtight cavity, controller valve is connected with a flexible pipe with gas compressor air outlet, the pressure of airtight cavity equals all the time gas compressor and goes out atmospheric pressure, and air pressure forms a pressure F4 in closed cavity controller spring; The unlatching of bypass valve or close is mainly subject to the directed force F 1 that pressure forms bypass valve before whirlpool, directed force F 2, the directed force F 3 of spring, the directed force F 4 of boost pressure to diaphragm that exhaust back pressure forms bypass valve, four active force co-controllings, when F1 moment and F4 moment sum are greater than F2 moment and F3 moment sum, bypass valve is in opening state, be less than or equal to, bypass valve is in closed condition.

There are following 2 risks in existing diesel turbosupercharger exhaust gas by-pass valve controlling method:

1. the elastomer diaphragm of controller inside, under hot environment, work for a long time, add lasting to-and-fro motion, ageing of rubber or fatigue fracture easily occur, the inner closed cavity that just cannot form of controller, F4 active force will disappear, exhaust gas by-pass valve will be all the time in closed condition, can bring super supercharging to motor, pressurized machine generation overspeed equivalent risk, rupture of diaphragm also can cause engine aspirating system gas leakage, causes engine power deficiency.

2. what connect controller valve and gas compressor air outlet is rubber hose, under hyperthermia radiation, also can have aging risk of rupture for a long time, works as hose fracture, there will be exhaust gas by-pass valve to open, the problems such as engine aspirating system gas leakage.

For above two risk points, when carrying out pressurized machine design, controller need to be arranged in to gas compressor one side of stow away from heat, this layout can be furnished with certain influence to the complete machine of pressurized machine, owing to being subject to the restriction of controller installation, blower outlet position just cannot planar rotation arbitrarily within the scope of 360 °, cause the pressurized machine versatility of same model lower.

Model utility content

The technical problem that the utility model mainly solves is to provide a kind of non-pneumatic type mechanical control device, makes controller architecture simpler, reduces amount of parts, and simplified processing process has reduced cost simultaneously.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of non-pneumatic type mechanical control device is provided, comprise: exhaust gas by-pass valve and the controller being connected with described exhaust gas by-pass valve, on discarded bypass valve, 2 active forces have been arranged, comprise the back of the body directed force F 2 that the front active force F1 that produced by turbosupercharger and exhaust back pressure produce, in described controller, be provided with a spring, the active force of described spring is acting force of the spring F3.

In preferred embodiment of the utility model, described front active force F1 is consistent with the direction of acting force of the spring F3.

In preferred embodiment of the utility model, the moment of front active force F1 is greater than back of the body directed force F 2 and acting force of the spring F3 sum, and described discarded bypass valve is opening state.

In preferred embodiment of the utility model, the moment of front active force F1 is less than or equal to back of the body directed force F 2 and acting force of the spring F3 sum, and described discarded bypass valve is closed condition.

The beneficial effects of the utility model are: the non-pneumatic type mechanical control device of the utility model has been cancelled elastomer diaphragm, can effectively solve the long-term work under hot environment of current diesel pressure booster bleed valve controller diaphragm, diaphragm lost efficacy and caused the motor problem that breaks down; Owing to there is no rubber parts in controller, temperature resistant capability improves greatly, can, in the higher pressurized machine whirlpool end assembling of temperature, no longer take gas compressor end spaces, and blower outlet is arranged more flexible, can improve the versatility of single model turbosupercharger simultaneously; Controller architecture is simpler, has reduced amount of parts, has simplified processing technology, has reduced cost simultaneously.

Embodiment

To the technological scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model is embodiment comprise:

A kind of non-pneumatic type mechanical control device, comprising: exhaust gas by-pass valve and the controller being connected with described exhaust gas by-pass valve.

On discarded bypass valve, arranged 2 active forces, comprised the back of the body directed force F 2 that the front active force F1 that produced by turbosupercharger and exhaust back pressure produce, be provided with a spring in described controller, the active force of described spring is acting force of the spring F3.Described front active force F1 is consistent with the direction of acting force of the spring F3.

4 active forces by existing controller are controlled the unlatching of exhaust gas by-pass valve or close, reducing to 3 current active forces controls, key is to have reduced the F4 active force in existing controller, and the minimizing of F4 active force will not need elastomer diaphragm, valve, airtight cavity in control assembly.

Because controller does not have the elastomer diaphragm easily losing efficacy, can effectively avoid causing the faults such as the super supercharging of motor or pressurized machine hypervelocity because elastomer diaphragm or rubber hose lose efficacy, in addition owing to there is no rubber parts in controller, temperature resistant capability improves greatly, can be in the higher pressurized machine whirlpool end assembling of temperature, no longer take gas compressor end spaces, blower outlet is arranged more flexible, can improve the versatility of single model turbosupercharger simultaneously.

The moment of front active force F1 is greater than back of the body directed force F 2 and acting force of the spring F3 sum, and described discarded bypass valve is opening state.
