Description

Multi-rotation thrust support

Technical Field

The utility model relates to an executor technical field, in particular to many gyration thrust support.

Background

The executor support is the part of connecting executor and valve body, generally includes two kinds, thereby one kind is for driving the epaxial rotation of support to drive the valve rod rotation through the executor, and another kind is to drive the epaxial slip from top to bottom on the support through the executor to the ground hole valve rod slides from top to bottom. The first type of actuator is typically an electric actuator and the second type of actuator is typically a pneumatic or hydraulic actuator. For example, the valve actuator which is disclosed in the Chinese invention patent with the publication number of CN109681649B and is convenient to mount and dismount is characterized in that the electric actuator drives the valve rod to rotate through the shaft of the bracket; china with publication number CN210752140U uses the mixer capable of adjusting the foam liquid proportion disclosed in the novel patent to realize adjustment by driving the valve rod to slide up and down by the hydraulic actuator. At present, the valve body for adjusting the flow rate with the valve rod sliding up and down is difficult to use an electric actuator with a rotary output end, and a relatively complex connecting structure is needed.

Disclosure of Invention

The utility model discloses a remedy prior art not enough, provide a many gyration thrust support.

The utility model discloses a realize through following technical scheme:

the utility model provides a many gyration thrust support, includes runner assembly and support body, the support body includes the mount pad through a plurality of stands and tray fixed connection, the bottom fixed mounting of mount pad has the sleeve pipe, the intraductal axle that installs of cover, be equipped with the guiding hole on the sleeve pipe, epaxial fixed mounting has the locating part that matches with the guiding hole, epaxial external screw thread that is equipped with, the internal thread toothing of the valve interface spare on external screw thread and the runner assembly.

The rotating assembly further comprises a mounting flange and a connecting flange, wherein the mounting flange and the connecting flange are respectively connected with the valve interface piece through bearings, and the mounting flange and the connecting flange are fixedly connected through screws.

A convex ring is arranged in the middle of the valve interface part, and the two bearings are respectively positioned at the top and the bottom of the convex ring.

The bearing is a thrust ball bearing.

At least two upright posts are arranged.

The utility model discloses following technological effect has:

the shaft of the utility model is fixedly connected with the rotating nut through the screw thread, the limiting part on the shaft is matched with the guide hole on the sleeve, when the rotating nut rotates, the shaft realizes vertical motion up and down due to the action of the limiting part, thereby converting the rotation of the electric actuator into the operation in the vertical direction; the utility model discloses the structure adds the subtraction list, is convenient for maintain.

Fig. 2 is a schematic structural view of the stent body.

In the figure, 1-mounting flange, 2-bolt, 3-valve interface piece, 4-bearing, 5-screw, 6-connecting flange, 7-O-shaped sealing ring, 8-tray, 9-upright post, 10-mounting seat, 11-shaft, 12-sleeve, 13-guide hole, 14-limiting piece, 15-fixing part and 16-connecting piece.

Detailed Description

In the present invention, the words describing the directional relationship such as "front", "back", "inner", "outer" are only used for convenience of description of the embodiment, and are not considered as limitations of the present invention. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The fixed connection mode comprises but is not limited to a connection mode known in the prior art, such as welding, screwing, clamping, interference fit, integral forming and the like; the number of the plurality is more than one.

Fig. 1 to 2 show an embodiment of the present invention. This embodiment provides a many gyration thrust support, including runner assembly and support body, wherein the support body includes mount pad 10, and mount pad 10 is through a plurality of stands 9 and tray 8 fixed connection, has sleeve pipe 12 at the bottom fixed mounting of mount pad 10, installs axle 11 in the sleeve pipe 12. The specific sleeve 12 is provided with two guide holes 13, a limiting member 14 matched with the guide holes 13 is fixedly mounted on the shaft 11, that is, the limiting member 14 is located in the guide holes 13, a connecting member 16 is detachably mounted at the bottom of the shaft 11 through a fixing member 15, and the connecting member 16 is used for being connected with the valve rod. The shaft 11 is provided with external threads.

The rotating assembly comprises a mounting flange 1, a valve interface piece 3 and a connecting flange 6, wherein the mounting flange 1 and the connecting flange 6 are respectively connected with the valve interface piece 3 through a bearing 4, the mounting flange 1 is positioned above the connecting flange 6, and the mounting flange 1 and the connecting flange 6 are fixedly mounted together through a screw 5.

As shown in fig. 1, a convex ring is arranged in the middle of the valve interface 3, and two bearings 4 are respectively arranged at the top and the bottom of the convex ring.

The valve interface 3 is provided with an internal thread which matches an external thread on the shaft 11.

The mounting flange 1 may be connected to the actuator by means of bolts 2.

In this embodiment, at least two upright posts are provided, and the bearings are thrust ball bearings.

When the valve is used, the valve interface part 3 is in threaded engagement with the shaft 11, the output end of the actuator drives the valve interface part 3 to rotate, and due to the blocking effect of the limiting part 14, the shaft 11 does not rotate but moves upwards or downwards in the vertical direction when the valve interface part 3 rotates, so that the valve rod is driven to move upwards or downwards.
