Abstract
The utility model discloses a spiral electric valve actuator, which is characterized by comprising a supporting cylinder (2), wherein a traction cylinder (6) is arranged in the supporting cylinder; the traction cylinder is fixedly connected with a control screw (3); a square motor connecting point (01) is carved on the top of the control screw; the neck of the control screw (3) is provided with a bearing (1); a limit switch (5) is arranged in the control screw; the limit switch is controlled by a guide rod (4) and a guide slot (4-1) to move up and down only; an outer magnetic ring (8) is sleeved outside the traction cylinder (6); and a magnetic sealing ring (7) is sleeved outside the outer magnetic ring. The supporting cylinder is fixed on the valve cover, so that the outer magnetic ring of the traction cylinder and an inner magnetic ring on a valve rod core are positioned on the same horizontal line so as to form the mutual actuation force; and when the valve is required to be opened, only the traction cylinder is only required to positively rotate, and when the valve is closed, the traction cylinder is only required to reversely rotate, and the valve is closed. In addition, the opening and closing in-place operations are controlled by the limit switch.
Description
Technical field
The utility model relates to a kind of valve supporting apparatus, more precisely is the execution utensil of the pressure self-enclosed control valve of a kind of supporting surperlight type.
Background technique
The history of human existing centuries of application to valve, that uses till today mainly contains stop valve, gate valve, butterfly valve and ball valve etc. always; And the seal ring requisite lifelong accessory that always is exactly any valve.Gap sealing between the rotation of particularly static valve gap and valve rod (sealing of living), and the various valves that are sealed in HTHP, its adjustment, to change seal ring just more frequent.Though world today's new and high technology is fast-developing, is just promoting aspect the material of seal ring also, and aspect valve design, do not implementing to get rid of the excellent process of using seal ring or improving the seal ring Environmental Conditions.
Summary of the invention
The purpose of the utility model is to provide a kind of supporting spiral electric valve actuator that is used for the pressure self-enclosed control valve of surperlight type.
In order to achieve the above object, the solution that the utility model is taked is: a kind of spiral electric valve actuator, and it has a shoring; Be provided with traction cylinder in the shoring, traction cylinder is fixedly connected with the control screw rod, and the control screw tip is carved into square motor tie point; The neck of control screw rod is equipped with bearing, is equipped with limit switch in the middle of the control screw rod, and limit switch is being controlled and can only moved up and down by guide rod and guide groove; The outside of traction cylinder is with outer magnetic ring, and outer magnetic ring overlaps the envelope magnet ring outward again.
During use, shoring is fixed on the valve gap.This final controlling element has been taked the mode of screw rod rotation, and the internal diameter size of traction cylinder is greater than valve closed cylinder external diameter 0.3mm, makes it be enclosed within the valve closed cylinder and lives outward and join.Shoring is fixed on the valve gap, makes the outer magnetic ring of traction cylinder and the internal magnetic ring on the valve rod fuse on same horizontal line, carry out mutual the suction-combining force; When valve need be opened, needing only carries out traction cylinder clockwise; Also only need traction cylinder be reversed when closing and just can realize closing; In addition, reaching position and pass puts in place and is all controlled by limit switch.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 01, motor tie point, 1, bearing, 2, shoring, 3, the control screw rod, 4, guide rod, 4-1, guide groove, 5, limit switch, 6, traction cylinder, 7, the envelope magnet ring, 8, outer magnetic ring, 9, set screw.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done description again.
Referring to Fig. 1; A kind of spiral electric valve actuator, it has a shoring 2, and shoring 2 is fixed on the valve gap; Be provided with traction cylinder 6 in the shoring 2; Traction cylinder 6 is fixedly connected with control screw rod 3, is equipped with limit switch 5 on the control screw rod 3, and guide groove 4-1 is controlling limit switch 5 by guide rod 4 can only be up and down; When this final controlling element was installed on the valve gap by set screw 9, its outer magnetic ring 8 was just in time implemented inside and outside the suction-combining force mutually with valve rod fuse internal magnetic ring at same horizontal line.When valve need be opened, needing only carries out traction cylinder clockwise; Also only need traction cylinder be reversed when closing and just can realize closing.In addition, reaching position and pass puts in place and all has limit switch 5 to control.
