Description

Technical Field

[0001] This utility model relates to the field of disassembly tools, specifically to a tool for disassembling and assembling a fluoropolymer-lined regulating valve seat. Background Technology

[0002] In the existing technology, in the production of polysilicon and chemical products, the regulating valve at the outlet of the hydrogen chloride synthesis furnace is mostly a PTFE-lined regulating valve. During use, because the valve seat of the PTFE-lined regulating valve is mostly made of PTFE soft seal, scratches may occur on the sealing surface, requiring replacement with a new valve seat.

[0003] Currently, there are no special tools available for disassembling and assembling valve seats, making it impossible to smoothly disassemble and assemble the seats of PTFE-lined control valves. Generally, one can only use a screwdriver-like rod-shaped tool to be inserted obliquely into the hole of the valve seat, and then use a hammer or other tools to strike the rod-shaped tool to disassemble the valve seat. This method is not only inefficient, but also easily damages the valve seat. Utility Model Content

[0004] The purpose of this invention is to develop a tool for disassembling and assembling fluoropolymer-lined control valve seats to improve the efficiency of valve seat disassembly and assembly.

In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a tool for disassembling and assembling a fluoropolymer-lined regulating valve seat, including a support 1, which is disc-shaped, and a support rod 2 is coaxially connected to the center of the support 1. A handle 3 is provided at the end of the support rod 2 away from the support 1.

[0035] The support 1 is provided with four sets of connecting mechanisms, which are arranged in a circular trajectory around the center of the support 1, and the four sets of connecting mechanisms are equally spaced on their arrangement trajectory.

[0036] The connecting mechanism includes a slide groove 8 provided on the support 1, which is radially opened along the support 1. An adjusting screw 4 is slidably provided in the slide groove 8. The bottom end of the adjusting screw 4 is provided with a base plate 6 that contacts the bottom of the support 1. The base plate 6 is disc-shaped and its outer diameter is larger than the width of the slide groove 8. An adjusting nut 5 that contacts the top of the support 1 is threaded onto the adjusting screw 4.

[0037] A push rod 7 is connected to the center of the bottom of the chassis 6, and the push rod 7 is coaxial with the adjusting screw 4. According to the valve seat model, adjust the position of the adjusting screw 4 in the slide groove 8 so that the position of the push rod 7 corresponds to the hole of the valve seat. Insert the push rod 7 into the valve seat hole, and rotate the handle 3 to disassemble or assemble the valve seat.

[0038] Example 2

[0039] like Figure 3 and Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the top rod 7 is also provided with a matching hole assembly, which contacts the inner wall of the valve seat hole.

[0040] In Example 1, since the outer diameter of the push rod 7 is fixed, when the inner diameter of the valve seat hole is larger than the outer diameter of the push rod 7, during the disassembly and assembly of the valve seat, not only is the push rod 7 prone to tilting and scratching the inner wall of the hole, but the localized stress on the inner wall of the hole can also easily lead to deformation and damage to the hole. In this example, the hole fitting assembly can automatically adjust its size according to the inner diameter of the hole, so that the size of the hole fitting assembly matches the inner diameter of the hole.

[0041] The fitting assembly includes a slide cylinder 10 sleeved on the top rod 7. The slide cylinder 10 and the top rod 7 are slidably connected coaxially. The bottom end of the top rod 7 is provided with an upward-opening screw hole. A lifting screw 12 is threaded into the screw hole. The lifting screw 12 is rotatably connected to the slide cylinder 10 and the two are fixed in the axial direction. The bottom end of the lifting screw 12 extends out of the slide cylinder 10. Tightening the lifting screw 12 causes it to rotate. The lifting screw 12 and the top rod 7 are threaded together to lift and lower the slide cylinder 10.

[0042] Six protective plates 9 are provided on the outer side of the slide cylinder 10. The protective plates 9 are vertically arranged and evenly spaced in a circular trajectory around the axis of the slide cylinder 10. The outer wall of the protective plate 9, that is, the side wall of the protective plate 9 away from the slide cylinder 10, is an arc-shaped surface, and the six protective plates 9 enclose a cylindrical shape. The top of the protective plate 9 is slidably connected to the bottom of the chassis 6. The chassis 6 is provided with a slide rail arranged radially and slidably connected to the top of the protective plate 9. Two transmission rods 11 are provided between the inner wall of the protective plate 9 and the outer wall of the slide cylinder 10. The two ends of the transmission rods 11 are hinged to the inner wall of the protective plate 9 and the outer wall of the slide cylinder 10, respectively. The projection of the transmission rods 11 on the horizontal plane is located radially on the slide cylinder 10.

[0043] Tighten the lifting screw 12. The lifting screw 12 and the push rod 7 are threaded together to drive the slide cylinder 10 to rise and fall. The rise and fall of the slide cylinder 10 drives multiple guard plates 9 to slide radially along the chassis 6 through the transmission rod 11 to move closer to or away from the slide cylinder 10, so that the diameter of the cylinder formed by the multiple guard plates 9 is adapted to the inner diameter of the valve seat hole.

[0044] In this embodiment, the lifting screw 12 is rotated to adjust the position of the guard plate 9 according to the inner diameter of the valve seat hole, so that the position of the guard plate 9 matches the hole. When disassembling and assembling the valve seat, after the matching assembly is inserted into the valve seat hole, the outer walls of the six guard plates 9 are in contact with the inner wall of the valve seat hole. During the disassembly and assembly of the valve seat, the inner wall of the valve seat hole is subjected to uniform force. The matching assembly is fixed in the valve seat hole and will not damage the valve seat hole. The disassembly and assembly tools will not slip or tilt.

[0045] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
