Abstract

FIELD: valving. SUBSTANCE: drive has clip wherein a bearing unit connected with a nut and interacting with a spindle is mounted. Between the clip and housing a cover is interposed. A gasket seal and race provided with two interconnected grooves are arranged. The inner groove that faces the spindle receives a rubber collar of square cross-section. The outer groove is in communication with passageways made in the cover. The passageways are provided with delivery and drain valves. In addition the diameter of the opening for the bearing unit is greater than the diameter of the cover of the gasket. The cover of the gasket is cylindrical and provided with dummy holes radially arranged on the surface. EFFECT: improved design. 2 cl, 2 dwg

Description

 The invention relates to pipeline valves, in particular to manual actuators used in wedge gate valves, shut-off valves.

 A known valve actuator, which consists of two rods having inclined grooves through which the common axis passes [1], This design has a low degree of maintainability, ie neither the packing gland nor the actuator part can be replaced without relieving the pressure of the medium when the latter is supplied to the plate and without depressurization of the valve.

 Also known is a valve [2] whose actuator consists of an packing, bearing assembly, manual actuator and direction indicator. To repair the actuator and replace the seal, the valve must also be depressurized.

 The objective of the invention is to increase the maintainability of the actuator by introducing the possibility of replacing the packing, bearing assembly without depressurization of the valve (valve, valve).

 The technical result is achieved by the fact that in the drive of the stop valves, containing a yoke connected to the valve body, in the lower part of which there is a stuffing box seal of the valve spindle, pressed through the sleeve by the stuffing box cover, and in the axial bore of the upper part, there is a bearing assembly connected to the running nut, interacting with the spindle, a cover is installed between the yoke and the housing, in which the stuffing box packing and the sleeve with two annular grooves interconnected are located in the inner channel A rubber cuff with a square cross section is located on the side of the spindle, and the outer groove is in communication with the channels made in the lid, in which the discharge and release valves are installed.

 In addition, the drive is characterized in that the diameter of the hole for the bearing assembly is larger than the outer diameter of the stuffing box cover.

 In addition, the drive is characterized in that the stuffing box cover is cylindrical with blind holes radially located on the outer surface.

 The drawing shows a longitudinal section of the drive.

 The actuator of the pipeline valves consists of a yoke cover 1, connected to the housing 2, between the flanges of which the cover 3 is placed. A spindle 4 is coaxially placed inside it, covering the wiper ring 5, a sleeve 6 with an inner ring groove 7, a rubber ring 8 and an outer ring groove 9, stuffing box 10, lip seal 11, stuffing box sleeve 12 and stuffing box cover 13.

 The threaded end of the spindle 4 is connected to the spindle nut 14, fixed in the sleeve 15, the shoulder of which is installed between two thrust ball bearings 16 and 17. The lower bearing 16 is connected to the base plate 18 and the bottom of the head of the yoke cover 1, and the upper one is pressed by the cover 18 to the same head .

 A flywheel 20 and a travel indicator 21 are mounted on the sleeve 15. The cover 3 has channels 22 and 23 connecting the outer annular groove 9 with the discharge 24 and the drain 25 valves.

 The drive operates in several modes.

 In the first operating mode, when the valve is under pressure, the actuator operates as follows. When opening or closing the valve, rotating the handwheel, 20 move the spindle 4. In this case, the wiper ring removes sediment from the passing medium from the spindle, and the lip seal 11 seals the movable joint.

 In the second, repair mode, when the valve is under pressure from a passing medium, but there is a leak through the lip seal 11.

 Without removing the pressure of the medium in the housing 2 through the discharge valve 24, and the channel 22 serves grease in the annular groove 9 and compresses the rubber ring 8 around the spindle 4. Then move the pointer 21, shut off the cover 19 and screw the sleeve 15 with the spindle nut 14, the upper bearing 17 from the spindle 4. Then unscrew the stuffing box cover 13, remove the stuffing box sleeve 12 and replace the lip seal 11. After assembling the actuator in the reverse order, release pressure from the rubber ring 8 by means of a drain valve Pan 25, and the fittings are again in good condition.

 Due to the fact that the design uses a rubber ring controlled by two valves, as well as the fact that the stuffing box cover is round and its diameter is smaller than the base plate of the head of the yoke cover, it became possible to repair the drive without depressurizing the valve body.

Claims (3)

 1. The actuator of the pipeline valves, comprising a yoke connected to the valve body, the lower part of which contains the packing of the valve spindle, pressed through the sleeve by the stuffing box cover, and in the axial bore of the upper part, the bearing assembly associated with the spindle nut interacting with the spindle, characterized in that a cover is installed between the yoke and the housing, in which the stuffing box seal and the casing with two annular grooves interconnected are located in the inner groove facing the spinels Yeh-lii located rubber sleeve with a square cross-section, and the outer groove communicates with the channels made in the cover in which are installed a pressure and bleed valves.
 2. The drive according to claim 1, characterized in that the diameter of the hole for the bearing assembly is larger than the outer diameter of the stuffing box cover.
 3. The drive according to claim 1 or 2, characterized in that the seal is cylindrical with blind holes radially located on the outer surface.
