SU396523A1 - VALVE WITH MOTOR1 DRIVE. ^^ - Google Patents

Description

 valves with m or ip m. DRIVE. M installed on the steam (gas) supply lines and used as -istable i.x. of automatic control systems.

Offered. The motor drive differs from the known ones that the lever-cam mechanism for transferring movement from the drive to the stem of the barred organ is made with a link that connects the specified P1TOK with the pusher and with the valve body with the saddle. separates the roller and cam.

Due to this, there is no need to fine-tune the moment when the actuator is turned off. In the position of the valve.

The proposed valve with a motor pr.shdom represented iia drawing.

On the body / clalana uatano.vlen kroishteyn 3, which is attached to the body 4 of the gland. Through the gland body 1 passage;) t the stem 5 of the closure member 2. The stem assembly 2 is provided with an elastic sealing ring 6. Through the link 7, the stem 5 is connected to the pusher 8. The pusher is connected to the cam 10 mounted on the drive shaft by means of roller 9. . Engine 11 is equipped with limit switches that allow it to be disconnected.

When applying voltage to the Far East) 1gatel (oir) 1al to the opening) the working shaft of the last (through the gearbox) rotates the cam 10. Rotating, the cam moves through the roller. 9 on the pusher 8. The pusher through the stud 7 acts on the rod 5, opening the locking organ 2, according to the law, assigned to the cam 10. After the locking organ under} 1 t, the limit switch trips engine power. When the iK-i signal is given, the valve closes the motor in the opposite direction. Under the action of the spring, the pusher 6, through the roller 9, rolling the npotJKLib cam 10, lowers, moving the needles. The locking member comes into contact with the saddle by closing the bore. The vapor pressure (gas) above the gorge)} The 1st organ tightly lies) 1mayet it to the saddle. In this case, the shackle 7 stops the pusher from twisting, the roller 9 is detached from the cam 10. The gap created between BAT allows to avoid precise control of the torque triggered; 1H of the engine switches.

Subject invention

1. Klanan with a motor shaft containing a lever for moving the movement from the drive to the brush from the locking member, characterized in that, in order to avoid or finely adjust the timing of the drive, the lever-cam mechanism is equipped with a link. the valve stem with the pusher and in contact with the saddle separates the roller of the pusher with the cam.

2. Valve in. 1, characterized in that the circular cam is underdetach with a p1 rotor, which sets the advantageous law of motion of the stem clainnia.
