[0026] Please refer to Figure 2A , which shows the combined state diagram of the device for improving the installation of the valve bellows provided by the embodiments of the application. As Figure 2A shown, the device is composed of a bracket 200 and a bolt assembly 201, the bolt assembly 201 is suspended on the top plate 203 of the bracket 200 through a bolt 202, and the bolt assembly 201 can reciprocate up and down along the center line of the circular hole 206 arranged in the center of the base 205 of the bracket 200. Exemplarily, the materials of the bracket 200 and the bolt assembly 201 are 304 stainless steel.

[0027] As Figure 2B shown, the bracket 200 is composed of a post 207 and a top plate 203 and a base 205 which extend from the top and bottom of the post 207 respectively in the same direction, the length of the top plate 203 and the base 205 are the same, the width of the top plate 203 and the base 205 are the same as the width of the post 207, and the thickness of the top plate 203 is smaller than the thickness of the base 205. A first threaded hole 208 which is used in conjunction with the bolt 202 is provided in the center of the top plate 203. A circular hole 206 is provided in the center of the base 205, the depth of the circular hole 206 is not more than half of the thickness of the base 205, and the diameter of the circular hole 206 is the same as the diameter of the valve bellows. The vertical distance between the center line of the first threaded hole 208 and the front end of the top plate 203 is equal to the vertical distance between the center line of the circular hole 206 and the front end of the base 205, i.e. the center line of the first threaded hole 208 is in the same line with the center line of the circular hole 206.

[0028] As Figure 2A and Figure 1 shown in the left drawing, the vertical height difference between the bottom surface of the top plate 203 and the top surface of the base 205 should ensure that the valve components and the pressing block 210 in the bolt assembly 201 shown in the left drawing can be accommodated. Figure 1

[0029] For example, the width of the post 207 is 100mm-120mm, the height of the post is 365mm-375mm, the length of the top plate 203 and the base 205 is 150mm-170mm, the thickness of the top plate 203 is 30mm-32mm, and the thickness of the base 205 is 35mm-40mm.

[0030] As Figure 2C shown, the bolt assembly 201 is composed of the pressing block 210 and the bolt 202, the pressing block 210 is composed of a cylindrical top cover 213, a circular ring-shaped base 215, and a plurality of support columns 216 which connect the cylindrical top cover 213 and the circular ring-shaped base 215, a pull ring 212 for rotating the bolt 202 is provided on the head 211 of the bolt 202, and a steel ball is embedded in the bottom end of the bolt 202. The pressing block 210 is fixed to the lower part of the bolt 202, the bolt 202 passes through the second threaded hole 209 provided in the center of the cylindrical top cover 213 and fastens the fastener to the top and bottom surfaces of the cylindrical top cover 213, the length of the part of the bolt 202 below the cylindrical top cover 213 is smaller than the length of the support columns 216. If the upper part of the screw rod of the bolt 202 has a larger diameter than the lower part, the cylindrical top cover 213 is clamped by the fastener and the upper part of the screw rod of the bolt 202, and the length of the lower part of the screw rod of the bolt 202 is smaller than the length of the support columns 216. For example, the fastener is a nut. For example, the number of the support columns 216 is three.

[0031] ​Exemplarily, the inner diameter of the annular base 215 is 30-35 mm, the outer diameter is 55-60 mm, the diameter of the cylindrical top cover 213 is the same as the outer diameter of the annular base 215, the thickness of the annular base 215 is the same as the thickness of the cylindrical top cover 213, and both are 10-15 mm, and the length of the support column 216 is 80-85 mm.

[0032] Exemplarily, the length of the screw rod part of the bolt 202 is 120-130 mm, the head 211 of the bolt 202 is a cylinder with a thickness of 15-20 mm and a diameter of 50-55 mm, and the inner diameter of the pull ring 212 is 70-75 mm.

[0033] When the device for improving the installation of a valve bellows is used, the bottom of the bellows is clamped in the central circular hole 206 of the bottom plate of the support 200, the bottom of the bolt assembly 210 of the device (the annular base 215 of the pressing block 210) is placed on the head of the valve, the bolt 202 in the bolt assembly 210 is rotated by the pull ring 212 to slowly press down the spring, and finally the screw connecting the shaft of the bellows is locked.

[0034] It should be noted that the diagrams provided in the embodiments only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The shape, number and proportion of each component in actual implementation can be arbitrarily changed, and the layout pattern of the components can be more complex.

[0035] In summary, the device for improving the installation of a valve bellows provided by the present application can be installed by one person alone, and since the spring is pressed tightly by the pressing block 210 during the process of locking the screw to the shaft of the bellows, the screw connecting the shaft of the bellows is not easy to damage, which improves the maintenance efficiency and success rate. Therefore, the present application effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.
