Description
Technical field
The utility model relates to field of mechanical technique, particularly a kind of pressurized machine exhaust gas by-pass valve with spacing anti-rotating function.
Background technique
In gas engine application, the Main Function of pressurized machine exhaust gas by-pass valve is the needs according to engine operation condition, and by adjustment exhaust gas bypass valve opening, adjustment whirlpool front exhaust pressure in real time, reaches with cold rear pressure in making and start operating conditions requirement.
In actual application, there is following defect in supercharger bypass valve design proposal general at present:
(1) due under external bleed pressure effect, bypass valve regulator is in over range opening state for a long time, adds the fatigue failure risk of diaphragm and spring in bypass valve regulator, and cause diaphragm cracking in regulator, regulator leaks gas.
(2) because bleed pressure is excessive, regulator traveled distance exceedes transit joint and reserves design space, and valve block may be caused to clash into transit joint and come off.
(3) because bypass valve valve block is in opening state for a long time, pulse gas blows valve block and rotates, and pin is wear and rupture in rotation, causes valve block to come off.
Model utility content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of pressurized machine exhaust gas by-pass valve with spacing anti-rotating function.
Invention thought of the present utility model is: a kind of pressurized machine exhaust gas by-pass valve with spacing anti-rotating function, devise position-limit mechanism in the regulators, can effective limit regulator diaphragm range, prevent diaphragm fatigue cracking, the problem that comes off that valve block shock transit joint occurs can be solved simultaneously; When valve block is fixed, have employed anti-rotation design, effectively can solve valve block and rotate the pin wear and rupture problem caused.
A kind of pressurized machine exhaust gas by-pass valve with spacing anti-rotating function, wherein, comprise one end and connect valve block, the other end connects the transmission lever of guide rod one end, described transmission lever one end is provided with connected transfer block, described guide rod the other end is placed in pressure governor, is circumferentially with diaphragm and spring, arranges the stop collar holding described guide rod between described spring and diaphragm at the guide rod being positioned at described pressure governor one section; One side of described valve block arranges Anti-rotary block and connecting rod, described Anti-rotary block and transfer block arrange through hole respectively, described connecting rod and transfer block are fixed by the through hole that described connecting rod runs through in described transmission lever and transfer block successively.
Described valve block is round pie, and described connecting rod is arranged on the circle centre position of described valve block.
Described stop collar is the cylindrical shape that one end is provided with flange, and its diameter is slightly larger than the diameter of described guide rod.
Described Anti-rotary block is L-shaped, and it is arranged along described valve block edge, and the through hole on it is corresponding with the through hole on described connecting rod.
Described valve block is positioned at and spiral casing of pressure booster.
During utility model works, a external gas source is by the diaphragm in driving pressure governor and spring, and drive guide rod to move, the transfer mechanism that is displaced through of diaphragm and spring is transferred on valve block by guide rod; A external gas source is changed by pressure, the size of adjustment diaphragm displacement, thus controls the gap between valve block and spiral casing of pressure booster; By the control to valve block aperture, control the exhaust energy of motor b scavenging action on booster turbine, thus control supercharger speed, realize the control to rear pressure cold in different operating mode.
By test, the beneficial effects of the utility model are:
1, in pressure governor, stop collar is devised, can the maximum displacement of limiting diaphragm and spring, thus reduce the fatigue wear of diaphragm and spring, reduce the maximum opening of valve block, prevent valve block from encountering spiral casing of pressure booster transit joint, cause valve block to come off;
2, valve block devises Anti-rotary block and transfer block, can effectively solve in conventional construction, brushed continuous rotation due to valve block by engine exhaust pulse, occur pin wear and rupture problem.
