(54) TURNING HANDLING

surfaces of the shaft housing and the axis, increase the tightness of the device. When working on the suction piping due to the differential pressure of the vacuum: cp T: the cavity of the device’s cavity acts on the cuff aperture; 1nnte .1ccn, which presses them against the sealing surface and reduces the likelihood of air leaks. Inside the cylindrical holder 3, a rotary disk 7 is mounted, which is articulated with the grooves of the shaft 5 in the axis 6 with the possibility of: joining ILX for mutual interfacing within fixed limits. The presence of gaps between the articulated surfaces of the disk and the shaft shaft and the axle axis: coordinates the possible manufacturing errors and facilitates installation and disassembly of the device. The axles of the shaft and the axle are dimensioned in price, respectively, in case 8 bearings; covers 9. The bearings 8 are closed by covers 10 and 11. In the grooves of the cylindrical holder 3, there are two "B3anM03a vieHHeMbix half rings 12" forming, their saddle and uirugo are co-actuated with the inner surface of the elastic ring seal 4. There is a way to set the self-aligning elements using the elastic ring seal 4. Through the elastic side of the elastic ring 4. which eliminates the need for labor-intensive fitting work. When the surfaces of the semirings in contact with the disk surface wear out, they are interchanged in order to increase the service life 2 times. Inside the cylindrical nozzles 2, they are elastically fixed with elastic rings 13 and 14 ", overlaying easily removable protective inserts 15 bs of a material of increased wear resistance, which can be rotated according to Meipe from ea. Elastic rings 13 and 14 compensate for possible FOCTJt inserts, protect the gaps between nozzles and protective inserts 15 from willow (NII hard particles, facilitate assembly and disassembly of the device. Cover 9 n case / connectors. Between themselves two diametrically located grippers :. mi 16 and wedge mi 17.

Lovorotnaya Caste works as follows.

When the shaft 5 rotates, the torque is transmitted to the turntable 7 and the opening or closing of the bore hole at the cornea / occurs.

The gate regulator is disassembled to replace, rotate and swivel the 180 ° rotary disk 7, the cylindrical holder 3, the floating half-rings 12, the protective inserts 15 when they are worn, or other manufacturing needs as follows. Knock 17 out, take off the grippers 16 and the cover 9, take out the cylindrical assembly.

clip 3 with floating interchangeable half-rings 12, elastic annular ring 4 and swivel disk 7. Remove elastic ring seal 4 from the cylindrical holder 3 and remove the floating interchangeable half-rings J2 of the saddle. The floating floating protective inserts 15 and the elastomeric rings 13 and 14 are removed. The assembly is carried out in the reverse order and sequence.

Due to the installation of the drive shaft in the valve body of the regulator, the need for disconnection of the actuator with the drive shaft and subsequent adjustment is eliminated, and the quick-disconnect connection of the parts of the cylindrical cage assembly with the floating semirings, saddles, elastic asoltsyrm seal, Grozorotymyyyyy mystone ring. floating light protective devices, p; tavo, k; housings with a lid with the help of wedge grips can reduce the time for their replacement by approximately 3 times a. Equal dimensional distribution of erosion on the floating interlocking semirings of the saddle, and the rotational disk and the floating protective inserts is achieved by their 4-fold permutation and a new turn of 180, which increases their service life 4 times irimno.

Reduced repair time and increased service life increases the overall reliability of the rotary valve.

FORUMUA AND 3 ABOUT AND

1. Rotary damper with a saddle made in the form of semirings and a disk storage-retracting body mounted on the rotary shaft, which is connected with it, is connected with it so that, in order to increase the pressure, the flap is provided with a cylindrical yoke installed in the housing with 1a :: rock grooves and an elastic annular cuff enclosing it, in which 1fold ;: erection, and the sweep-rings of the slingshock through the grooves of the yoke are fitted into the grooves n and n - displacement.

2. Flap on c. 1, characterized in that the end surfaces of the half-rings of the saddle are mated with the cylindrical surface of the shaft of the locking and regulating member.
