    The invention can be used to adjust the valve of a compressor under various conditions of its operation, in particular when changing the number of revolutions or compressible gas. The method consists in that when reducing the number of revolutions or compression of gas with a lower specific weight, the force of the springs acting on the valve is reduced, and with an increase in the number of revolutions or compression of gas with a large specific weight, the force of the springs increases. In the valve part of the springs 6 is fixed on the plate 8, which is installed on the outer side of the limiter 3. The adjusting force acts through the transmission mechanism on the plate 8, changing the distance a between it and the limiter 3. This causes the height of the springs 6 to change. revolutions or compression of gas with a lower specific weight, the height of the springs 6 is increased, reducing their force. With increasing speed or compression of gas with a large proportion of the height of the spring 6 is reduced. 2 sec. and 2 z. p. f-ly, 2 ill.

    专利说明:

    The invention relates to a compressor industry and can be used in valves of piston compressors under various conditions of compressor operation, especially when changing the number of revolutions or when assigning gases with different specific gravity to compression.
    The purpose of the invention is to increase reliability.
    According to the invention, the valve is controlled by forcing the spring force, the spring force is reduced by decreasing the number of revolutions or compressing the gas with a lower specific weight and the force of the springs is increased by increasing the number of revolutions or compression of the gas with a higher specific weight, and the spring force is varied continuously.
    Figure 1 shows the discharge valve; figure 2 - suction valve.
    The valve contains a saddle 1 with channels 2 for the passage of gas, a limiter 3 lifting, located between the valve body 4, pressed to the saddle 1 by springs 5 and 6 installed in the holes 7 of the limiter 3, and a device for changing the spring force 6 the spring force is made in the form of a plate 8 and a transmission mechanism connected with it, at least part of the holes 7 of the limiter 3 are made through, and the plate 8 is located on the outer side of the limiter 3 with the possibility of stepless action installed in a well znyh holes 7 by springs 6.
    In the case of valve execution, the injection gear mechanism is made in the form of a spindle 9, a stop bushing 10, a mounting bushing 11, a return spring 12, a washer 13 and a lock nut 14. The spindle 9 is located along the valve axis, fixed on the saddle 1 and pointing towards the limiter 3 , stop sleeve 10, adjusting sleeve 11, return spring 12 and washer 13 are located on the outside of limiter 3 coaxially to spindle 9, saddle 1 and limiter 3 are fastened with nut 14 to spindle 9 through stop sleeve 10 and washer 13, plate 8 is fixed to mounting sleeve 11, and vtu 11 is located on the stop sleeve 10 with the ability to move

    along the valve axis under the action of the adjusting force 15 or under the action of the return spring 12 against the stop in the washer 13.
    If the valve is made with a suction transfer mechanism, it is made in the form of an anvil 10, a spindle 9, a tightening nut 16, a return spring 12, a washer 13 and an O-ring 17, an anvil 10 located along the valve axis and directed towards the seat 1, a saddle 1 and limiter 3 are fastened with a nut 16 on the sleeve 10, the spindle 9 is fixed on the plate 8 and mounted on the sleeve 10 so that it can move along the valve axis, the washer 13 is fixed on the spindle 9 on the side opposite to the plate 8, the return spring 12 is located between the washer 13 and nut 16, and 0-count 17 on the spindle 9.
    The restrictor 3 is provided with passageways 18, between the seat 1 and the restrictor 3 a stroke insert 19 is installed, in the discharge valve the return spring 12 is fixed by a cover 20, in the suction valve the stop sleeve 10 is provided with a shoulder 21 for tightening the saddle 1 and restrictor 3.
    The plate 8 is relatively limited. The l 3 can move within the distance a.
    In the discharge valve, when reducing the number of revolutions and compression of gas with a lower specific weight, the force of the springs 6 is forcibly reduced as follows. Reducing the setting force 15, the return spring 12 through the cover 20 displaces the sleeve 11 with the support 8 fixed on it. At the same time, the washers 13, the sleeve 10, the spindle 9, the stopper 3, the liner 19 and the saddle 1, having been fixed by the nut 14, remain stationary. Therefore, within the distance a, the height of the springs 6 installed in the through holes 7, i.e. their effort is reduced.
    In the discharge valve, the force of the springs 6 increases as the number of revolutions increases or when the gas is compressed with a large specific gravity, increasing the adjusting force 15. At the same time, within the distance a, the springs 6 are compressed.
    When the discharge valve is open, the valve A is lifted up to the stop in the stopper 3, and the gas passes through the channels 2 and 18.
    In the suction valve with a decrease in the number of revolutions and compression of gas with a lower specific weight, the force of the springs 6 is forcibly reduced as follows. Increasing the setting force 15, overcoming the resistance of the spring 12, move the spindle 9 and the plate 8. At the same time, the sleeve 10 and the saddle 1 between the collar 21 and the nut 16 are moved, the liner 19 and the distributor 3 remain stationary. Therefore, within the distance a, the height of the springs 6 increases, i.e. their effort is reduced.
    In the suction valve, the force of the springs 6 is increased by increasing the number of revolutions or by compressing the gas with a large specific gravity, reducing the adjusting force 15. At the same time, within the distance a, the springs 6 are reduced.
    When the suction valve is open, the locking member 4 is lowered all the way into the stopper 3, and the gas passes through channels 2 and 18,
    In all cases, the springs 5 are not adjustable.
