Abstract
The invention belongs to diesel engine test technical field, relate to a kind of device that carries out exhaust back pressure adjusting for diesel engine test process. This device comprises gas cylinder, valve gap, guide rod, valve body, gland, adjustment spring, guide cylinder, location-plate, backstay, locking nut, demarcation pull bar and counterweight. Use after the present invention, only need regulating spring pretightning force, just can simulate the test of diesel engine under specific environment, not only make process of the test simplify, also can shorten the test period, save experimentation cost.
Description
Technical field
The invention belongs to diesel engine test technical field, relate to a kind of for diesel engine test mistakeIn journey, carry out the device of exhaust back pressure adjusting.
Background technology
Diesel engine, under some specific environment, there will be exhaust back pressure different from atmospheric pressureSituation. Complete diesel engine starting test and performance test under this kind of environment, conventionallyIn situation, diesel engine can be placed in this environment and test, but this can cause process of the testComplexity, the test period lengthens, and has also greatly increased experimentation cost.
Summary of the invention
Object of the present invention, just in order to solve the deficiencies in the prior art, proposes a kind of for adjustingThe device of the exhaust back pressure of joint diesel engine, to meet the examination of simulation diesel engine under specific environmentTest needs.
Technical scheme of the present invention is, a kind of exhaust back pressure adjusting device for diesel engine,Comprise gas cylinder, valve gap, guide rod, valve body, gland, adjustment spring, guide cylinder, locationPlate, backstay, locking nut, demarcation pull bar and counterweight, valve body is fixed on gas cylinder,The ballhead of guide rod is connected with the spherical pit of valve gap, and fastening with gland, adjusts spring solidFix between gland and guide cylinder, there is screw thread guide cylinder outside, and is fixed on locking nutOn location-plate; Four backstay one end are connected with location-plate, and the other end is connected with valve body, andLocation-plate and valve body are maintained a certain distance; Demarcate of pull bar and be threaded, and leadThe female one end of being with of bar connects, and the other end of demarcating pull bar hangs counterweight, is carrying outWhen exhaust back pressure regulates, hang the counterweight suitable with required exhaust back pressure pressure, due to counterweightThe effect of gravity, valve gap moves downward, and separates with valve body, and guide cylinder is adjusted in rotation, makes to leadUpwards push up adjustment spring to cylinder, make valve gap and the opening of valve body in separating, thisTime, exhaust back pressure pretightning force and Weight gravity are suitable, finally tighten locking nut, make at bavinWhen oil machine work, exhaust back pressure can not change.
Beneficial effect of the present invention
The present invention is a kind of exhaust back pressure adjusting device for diesel engine, uses after the present invention,Only need regulating spring pretightning force, just can simulate the test of diesel engine under specific environment, noOnly make process of the test simplify, also can shorten the test period, save experimentation cost.
Brief description of the drawings
The present invention has 1 width accompanying drawing, is also most preferred embodiment figure of the present invention, also can sayBright book extract accompanying drawing.
The structural representation of Fig. 1, a kind of exhaust back pressure adjusting device for diesel engine.
Detailed description of the invention
Below in conjunction with accompanying drawing, most preferred embodiment of the present invention is further described.
As shown in Figure 1, a kind of exhaust back pressure adjusting device for diesel engine, comprise valve gap 2,Guide rod 3, valve body 4, gland 5, adjustment spring 6, guide cylinder 7, location-plate 8, backstay9, locking nut 10, demarcation pull bar 11 and counterweight 12.
Valve body 4 is fixed on gas cylinder 1, the spherical recess of the bulb of guide rod 3 and valve gap 2Inner side is connected, and fastening with gland 5, adjusts spring 6 and is fixed on gland 5 and guide cylinder 7Between. There is screw thread guide cylinder 7 outsides, and are fixed on location-plate 8 with locking nut 10.Four backstay 9 one end are connected with location-plate 8, and the other end is connected with valve body 4, and make to determinePosition plate 8 and connect valve body 4 and maintain a certain distance. One that demarcates pull bar 11 is threaded,Be connected with the female one end of being with of guide rod 3, the other end of demarcating pull bar 11 hangs counterweight
12。
In the time carrying out exhaust back pressure adjusting, hang the counterweight suitable with required exhaust back pressure pressure12, due to the effect of counterweight 12 gravity, valve gap 2 moves downward, separate with valve body 4, thenRotary steering cylinder 7, upwards pushes up guide cylinder 7 and adjusts spring 6, makes valve gap 2 and valve body 4 placesIn the opening that will separate, now, exhaust back pressure pretightning force is suitable with counterweight 12 gravity,Finally tighten locking nut 10, make in the time that diesel engine is worked, exhaust back pressure can not change.
This apparatus structure feature is in design valve gap 2 and guide rod 3, has adopted spherical jointConnect, make valve gap 2 rapid with guide rod 3 motion in the time opening, and avoided due to processingOr installation misaligns the catching phenomenon generation that error produces.
The present invention is a kind of exhaust back pressure adjusting device for diesel engine. Use after the present invention,The counterweight that only need load as required constant weight, the pretightning force of regulating spring, just can be realNow adjust the adjusting of diesel exhaust gas back pressure. This device uses simple, not only can simplify examinationTest process, can also reduce experimentation cost.
