Description

The utility model relates to the field of mechanical engineering, namely valve engineering, in particular to actuators of pipeline valves, mainly for ball valves, and can be used in oil and gas, petrochemical and other industries.

Known part-turn actuator for pipe fittings (see RU 161899 F16R 31/10), containing a cylindrical body in which a spindle is mounted diametrically opposite on the rotating bearings, controlled by a spindle nut fixed in a slider having two coaxial opposite trunnions mating through bodies of revolution with grooves of the double wings, the course of the latter is limited on both sides by stoppers. On the bottom side of the wings, an adapter is made for connection with pipe fittings, and on the upper side, an indicator of the position of the locking element of the pipe fittings is made.

The disadvantages of the known solutions include low consumer properties due to the long open-closed cycle time in the presence of a single rotor speed, and therefore the movement of the spigot.

Also known (see RU 189234 F16R 31/00) is a part-turn two-speed actuator for pipe fittings, a prototype comprising a housing in the wall of which is located in opposite rotating bearings, controlled by a flywheel through a planetary mechanism, a spindle interacting with a spindle nut connected to an axle on opposite fingers which has crackers installed, interacting with the grooves of the double wings connected to the adapter to control the pipe fittings.

The disadvantages of the known solutions include low consumer properties, namely the lack of tuning for a specific torque required to control the pipe fittings.

The technical problem to be solved by this utility model is to increase the consumer properties of the drive by changing it to the required torque and changing the angular velocity of the shut-off element of the pipe fittings.

The problem is solved in that the part-turn actuated actuator for pipe fittings, comprising a housing in the wall of which is located in opposed rotating supports controlled via a planetary mechanism, or directly by a flywheel, a spindle interacting with a spindle nut located on opposite fingers with crackers placed in the grooves of the double link connected to the adapter to control the pipe fittings, the running nut is normally equipped dix to its axis to adjust the guide mechanism and displacement pin with breadcrumbs interacting with double grooves scenes and scenes on the upper plate corresponding to certain fission applied torque generated by the drive, and on the upper finger stud is fixed pointer

In FIG. 1 shows a top view of a part-turn readjustable actuator; in FIG. 2 is a section along AA in FIG. 1;.

A part-turn rotatable actuator for pipeline valves consists of a housing 1, a rotary screw 3 mounted through a planetary mechanism 4 or directly by a flywheel 5 is installed in opposite rotating bearings 2.

A lead nut 6 is placed on the lead screw 3, with a tuning mechanism 7 mounted normally to its axis, comprising guides 8, a screw 9 controlling the pin 10, crackers 12 installed on the opposite fingers 11 located in the upper 13 and lower 14 back plate plates equipped with an adapter for controlling the pipeline fittings (not shown in FIG.). A pointer 15 is fixed on the upper finger 11 of the pin 10. And on the upper plate 13 of the backstage there are marks 16 corresponding to a certain torque transmitted by the adapter to the valve stem.

On the body 1, the backstop 17 stroke limiters are installed.

The part-turn rotatable actuator for pipeline valves is adjusted to the required torque for operation as follows.

With the cover removed from the housing 1 (not shown in Fig.) By the screw 9 of the adjustment mechanism 7, we move the pin 10 between the plates 8 until the pointer 15 is aligned by dividing 16, after which we fix the screw 9.

The drive is ready for operation.

The operation of a part-turn rotatable actuator for pipeline valves.

By rotating the handwheel 5 clockwise (we close the pipe fittings), the driving nut 6 moves along the traveling screw 3 transmitting force through the guides 8, pin 10, fingers 11, crackers 12 to the wings 13 and 14, which, depending on the shoulder relative to the center of rotation of the adapter, create torque transmitted to the valve stem.

In this case, the angular velocity of the locking element, such as a ball in a ball valve, will be different for each division 16. The further the division 16 from the center of rotation of the wings, the more its angular velocity of rotation will be lower and vice versa. Since the rotation of the ball by 90 ° remains constant, and the time at a constant linear speed of the axle 10 from the interaction with the spindle 3 controlled by the flywheel 5 is different, that is, the closer the division 16 is to the center of rotation of the wings, the less time. Thus, how many divisions will be applied 16 as much and there will be angular velocities of rotation of the ball.

Thus, due to the fact that the running nut is equipped with a trunnion movement mechanism by the control link, not only is the drive adjusted to the required torque to close the pipe fittings, but also the angular velocity of its shut-off element is changed.

Everything in the compartment undoubtedly improves the consumer properties of the drive.
