SUMMARY

[0005] The utility model discloses a fixing structure of titanium material equipment connecting pipe, which solves the technical problem of how to ensure that the connecting pipe made of titanium material has sufficient strength while reducing the use amount of titanium material and reducing the cost.

[0006] The objective of this utility model can be achieved through the following technical solution: a fixing structure for a titanium equipment connector, wherein the titanium equipment includes a vessel body, an insulation layer is provided between the inner and outer walls of the vessel body, the outer wall of the vessel body is made of stainless steel, characterized in that the inner wall of the vessel body is made of titanium, the connector is made of titanium, the fixing structure includes a sleeve made of stainless steel, a flange made of stainless steel, and a bushing made of titanium, the inner end of the connector passes through the insulation layer and is welded and fixed to the inner wall of the vessel body, the sleeve and the flange are both fitted outside the connector, the inner end of the sleeve is welded and fixed to the outer wall of the vessel body, the outer end of the sleeve is welded and fixed to the flange, the bushing is welded and fixed to the outer end of the connector, and the bushing abuts against the outer end face of the flange.

[0007] The inner wall of the vessel and the connecting pipes come into contact with the material, so they are made of titanium to improve the corrosion resistance and non-polluting properties of titanium equipment. The outer wall of the vessel and the flanges do not come into contact with the material, so they are made of stainless steel to reduce the amount of titanium used and lower the cost of titanium equipment. The sleeve connects to the flange, which is used to connect the outer connecting pipe. The bushing is fitted against the outer end face of the flange, integrating the bushing, flange, sleeve, and connecting pipe into a single unit. This ensures sufficient strength and a high degree of stability after the connecting pipe is installed and fixed. The insulation layer provides insulation, and the bushing against the outer end face of the flange also provides a seal, ensuring the insulation layer's effectiveness.

[0008] In the aforementioned fixing structure for the titanium equipment connector, the inner wall of the sleeve and the outer wall of the connector are fitted with a clearance fit. The sleeve isolates the titanium material from the outside environment, making the connector less susceptible to damage.

[0009] In the aforementioned fixed structure for the titanium equipment nozzle, the inner end of the sleeve extends through the outer wall of the vessel body into the insulation layer. This structure increases the contact area between the sleeve and the outer wall of the vessel body, improves the firmness of the connection between the sleeve and the vessel body, and thus enhances the firmness of the nozzle connection.

[0010] In the aforementioned fixing structure for the titanium equipment nozzle, the corner of the inner ring at the outer end of the flange is rounded. This structure provides sufficient space at the weld between the bushing and the nozzle, improving the weld strength and thus enhancing the secure connection of the nozzle.

[0011] In the aforementioned fixing structure for the titanium equipment nozzle, the flange has several through fixing holes, all of which are located circumferentially outside the bushing. Bolts are inserted into these fixing holes and tightened to allow the nozzle to connect to external parts.

[0012] Compared with the prior art, the fixing structure of the titanium equipment pipe provided by this utility model has the following advantages:

[0013] 1. The inner wall of the vessel body and the connecting pipes that come into contact with the material in this titanium equipment are made of titanium, while the outer wall of the vessel body, flanges and sleeves that do not come into contact with the material are made of stainless steel. This reduces the amount of titanium used and can reduce the cost of titanium equipment.

[0014] 2. The bushing of this titanium material equipment is attached to the outer end face of the flange, integrating the bushing, flange, sleeve and pipe into one unit. This ensures that the pipe has sufficient strength after installation and fixation, and the pipe is highly secure. At the same time, the bushing attached to the outer end face of the flange plays a sealing role, ensuring the insulation effect of the insulation layer. Attached Figure Description
