Abstract
The utility model relates to an air releasing valve for a gas generator of a combustion engine which is composed of a barrel body, a valve and a pair of mounting seats. The valve is fixed at the upper and the lower mounting seats and is assembled in the barrel body, and the lower mounting seat is connected with the barrel body through a pin shaft which is fixed on the barrel body. Movable match is used at the position between the pin shaft and a hole of the lower mounting seat on the barrel body, and the end is a driven end. The inner side of the upper mounting seat is connected with a shaft sleeve and a rocker arm which are positioned by a notch, and the outer side is also fixed with a bush, a spacing sleeve and the rocker arm which are fixed on the barrel body through a long screw bolt which is inserted in a screw thread hole of the upper mounting seat to form a driving end. The included angle alpha among common centerlines of two mounting seats and a horizontal centerline of the valve is five to fifteen DEG, and the common centerlines of two mounting seats pass through the center of the valve. The utility model has the advantages of simple structure, stable operation, reliability, and convenience.
Description
Affiliated technical field
The utility model belongs to the matching parts on the combustion machine gas generator, particularly guarantees the air bleed valve of gas generator energy stable operation in start-up course.
Background technique
More the existing blow-off system that is applied on the aeroengine adopts adjustable vane or venting to bring and guarantees motor energy stable operation in start-up course, this system architecture complexity, maintenance inconvenience, poor reliability.
Summary of the invention
At the deficiency that existing combustion machine gas generator blow-off system exists, the utility model provide a kind of simple in structure, be convenient to safeguard, handle steady, convenient and reliable air bleed valve.
The utility model is made up of cylindrical shell, valve and a pair of fitting seat.Valve is assembled in the cylindrical shell by upper and lower fitting seat fixed thereon, and the sealing between cylindrical shell realizes by the O RunddichtringO, and the below of valve is by bearing pin and following fitting seat of screw, and the top is fixed one with identical form and gone up fitting seat.Following fitting seat links to each other with cylindrical shell by the bearing pin that is fixed on the cylindrical shell, and for movingly, this end is a driven end between the following fitting seat hole on bearing pin and the cylindrical shell.Last fitting seat inboard links to each other with rocking arm with axle sleeve with notch location, its outside then with the lining that is fixed on the cylindrical shell, spacer sleeve and rocking arm are with inserting upward the interior stay bolt of the fitting seat tapped hole formation drive end that is fixed together.The horizontal center line angle α of the common centreline of two fitting seats and valve is 5 °～15 °, for the valve activity freely, this common centreline must be by the center of valve, valve rotates around this common centreline.
This valve is experienced rotary speed working, and when gas generator during at vehicle stop state, this air bleed valve is opened, and promptly valve is in the plumb position; When the conversion rotation speed n
InpWhen 85-90%, air bleed valve progresses into closed condition by open mode, and valve is in closed condition all the time when steady-working state, and promptly valve is horizontal.
The pass of valve, close that action is to control by the pressurized strut hydraulic control system that connects together with rocking arm, the stroke of pressurized strut is 40～60mm, spring is installed in pressurized strut, if when not having oil in the pressurized strut, spring all the time with piston head to the left hand limit position, rocking arm is in 45 ° of positions of left at this moment, and valve is in open mode; When hydraulic oil when the right side of pressurized strut infeeds, piston is shifted to right-hand lentamente, rocking arm is at right-hand 45 °, valve is in closed condition.In 90 ° action, piston takes the air line, and rocking arm has slotted hole because of it, and walks 90 ° arc.
The utlity model has simple in structure, be convenient to safeguard, handle advantages such as steady, easy to use, good reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the right elevation of Fig. 1,
Fig. 3 be the A of Fig. 2 to view,
Fig. 4 is that the B of Fig. 1 is to view.
1 bend pipe among the figure, 2 cylindrical shells, 3 times fitting seats, 4 bearing pins, 5 screws, 6 valves, fitting seat on 7,8 rocking arms, 9 spacer sleeves, 10 linings, 11 pistons and piston rod, 12 pressurized struts, 13 springs
Embodiment
As shown in Figure 1 and Figure 2, this air bleed valve is by bend pipe 1, cylindrical shell 2, and following fitting seat 3, bearing pin 4, screw 5, valve 6, last fitting seat 7, rocking arm 8, spacer sleeve 9, lining 10, piston and piston rod 11, parts such as pressurized strut 12 and spring 13 are formed.
Wherein valve 6 is assembled in the cylindrical shell 2 by last fitting seat 7 fixed thereon, following fitting seat 3, and the sealing between the cylindrical shell is realized by the O RunddichtringO, fix a following fitting seat 3 by two bearing pins 4 and 6 screws 5 below valve 6, the top is fixed one with identical form and is gone up fitting seat 7.
Following fitting seat 3 links to each other with cylindrical shell 2 by the bearing pin 4 that is fixed on the cylindrical shell 2, and for movingly, this end is a driven end between following fitting seat 3 holes on bearing pin 4 and the cylindrical shell 2.
Last fitting seat 7 inboards link to each other with rocking arm 8 with axle sleeve with 4 notches location, its outside again with the lining 10, spacer sleeve 9 and the insertion of rocking arm 8 usefulness that are fixed on the cylindrical shell 2 on stay bolt in fitting seat 7 tapped holes formation drive end that is fixed together.
Two fitting seats 3 and 7 common centreline and the horizontal center line angle α of valve 6 are 10 °, for the valve activity freely, this common centreline must be by the center of valve 6, valve 6 is around this center line rotation.
Valve 6 is the valve closed condition when being horizontal, and is the open mode of valve when being in the plumb position.Valve 6 is to lean on pressurized strut 12 hydraulic control systems that connect together with rocking arm 8 to control, the stroke of pressurized strut 12 is 50mm, spring 13 is installed in pressurized strut 12, when if pressurized strut 12 does not have oil, spring 13 all the time with piston and piston masthead to the left hand limit position, at this moment, rocking arm 8 is in 45 ° of positions of left, and valve is in open mode; When hydraulic oil when the right side of pressurized strut 12 infeeds, piston and piston rod 11 are shifted to right-hand lentamente, rocking arm 8 is in right-hand 45 ° of positions, valve 6 is in closed condition.In 90 ° action, piston and piston rod 11 take the air line, and rocking arm 8 is walked 90 ° arc because of it has slotted hole.Thereby guaranteed the steady-working state of combustion machine gas generator in start-up course.
