Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, a high temperature heat insulation support 100 includes: the lower heat insulation frame 10, the upper heat insulation frame 20, the inclined wedge 30, the adjusting bolt 40 and the fixing bolt 50.
The high temperature heat insulation support 100 realizes connection between the valve body and the actuator. Specifically, the lower heat insulating frame 10 is used to connect the valve body. The upper thermal insulation frame 20 is used for connecting an actuator. The tapered wedge 30 is used to adjust the distance between the upper and lower heat-insulating frames 10 and 20. The adjusting bolt 40 is used to push the wedge blocks 30 to slide to adjust the distance between the upper and lower heat-insulating frames 10 and 20. The fixing bolt 50 is used to fix the upper and lower heat-insulating frames 20 and 10.
As a specific embodiment, the lower heat insulating frame 10 includes: a lower bushing portion 11, a lower support plate portion 12, and a vertical wall portion 13. The lower support plate portion 12 connects the lower bushing portion 11 and the vertical wall portion 13. The lower bushing portion 11, the lower support plate portion 12, and the vertical wall portion 13 are integrally formed as one piece. The lower support plate portion 12 is provided with a slide rail 121 for guiding the slide of the wedge 30.
As a specific embodiment, the upper heat insulating frame 20 includes: an upper sleeve portion 21, an upper support plate portion 22, and a fixing wedge portion 23. The upper support plate portion 22 connects the upper bushing portion 21 and the fixed wedge portion 23. The upper sleeve portion 21, the upper support plate portion 22, and the fixing wedge portion 23 are integrally formed as one piece.
The upper sleeve portion 21 is fitted over the outer periphery of the lower sleeve portion 11. The nesting of the upper and lower sleeve portions 21, 11 provides for centering of the lower and upper thermal frames 10, 20 to avoid skewing of the valve stem or actuator rod connecting the actuator and valve body. A valve stem or drive rod passes through the centers of the upper and lower sleeve portions 21 and 11.
The tapered wedge 30 is in contact with the fixed wedge portion 23. The tapered wedge 30 is located below the fixed wedge portion 23 and supports the fixed wedge portion 23. The adjusting bolt 40 is screwed to the vertical wall portion 13. One end of the adjusting bolt 40 abuts against the wedge 30 to push the wedge 30 to slide along the slide rail 121. When the adjusting bolt 40 is screwed in, the adjusting bolt 40 pushes the wedge 30 to slide along the slide rail 121 toward the lower sleeve portion 11. At this time, the tapered wedge 30 pushes up the upper heat insulating frame 10 in cooperation with the fixed wedge portion 23, and increases the distance between the lower heat insulating frame 10 and the upper heat insulating frame 20.
The vertical wall portion 13 is formed with a kidney-shaped hole 131 through which the fixing bolt 50 passes. The fixing bolt 50 is fixed to the fixing wedge portion 23 through the kidney hole 131. The longitudinal direction of the kidney-shaped hole 131 is the height direction of the high temperature heat insulation support 100, i.e., the direction in which the upper heat insulation frame 10 moves with respect to the lower heat insulation frame 20. The depth direction of the waist-shaped hole 131 is parallel to the sliding direction of the wedge 30.
In a specific embodiment, the wedge 30 is provided with a wedge surface. The distance from the side of the cam surface close to the vertical wall portion 13 to the lower support plate portion 12 is greater than the distance from the side of the cam surface remote from the vertical wall portion 13 to the lower support plate portion 12. The fixed wedge portion 23 is provided with a mating wedge surface which is attached to the tapered wedge surface. When the adjusting bolt 40 is screwed in to push the wedge block 30 to be far away from the vertical wall part 13, the wedge surface of the wedge block 30 is matched with the matching wedge surface of the fixed wedge block part 23 to jack up the upper heat insulation frame 10.
As a preferred embodiment, the number of the tapered wedges 30 is 2. Two wedges 30 are provided on either side of the lower casing section 11. Specifically, the number of the vertical wall portion 13, the fixed wedge portion 23, the slide rail 121, the adjusting bolt 40, and the fixing bolt 50 is 2. Two fixed wedge portions 23 are provided on both sides of the upper sleeve portion 21. Two stationary wedge parts 23 are located between the two upright wall parts 13. A fixed wedge portion 23 is located between the upright wall portion 13 and the upper sleeve portion 21. The upper thermal frame 20 is symmetrical about a plane of symmetry. The lower thermal insulation frame 10 is symmetrical about a plane of symmetry.
When mounting, the tapered wedge 30 is first set to abut against the inside of the upright wall portion 13. The lower and upper heat-insulating frames 10 and 20 are connected to the valve body and the actuator, respectively. Screwing in the adjusting bolt 40 pushes the inclined wedge 30 to move until the lower and upper heat insulation frames 10 and 20 are in a tensioned state. The upper and lower heat-insulating frames 20 and 10 are fixed by tightening the fixing bolts 50.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
