Description

Technical Field

[0001] The utility model relates to the technical field of heating belts, in particular to a gas distribution disk heating belt structure. Background Art

[0002] A gas distribution plate is a device used to distribute gas from one source to multiple outlets. Its main function is to control and distribute the flow of gas or liquid to ensure energy transfer and flow control during the production process. Since gas may condense due to temperature drop during the distribution process, condensation will not only affect the gas distribution effect, but may also cause equipment failure or damage. Therefore, it is necessary to install a heating belt to maintain the temperature in the gas distribution plate and its pipelines to prevent gas condensation, thereby extending the service life of the equipment.

[0003] Generally, the heating tape can be directly wrapped around the outside of the distribution plate for heating. The heating tape and the distribution plate are fixed by adhesive. Although its installation is simple and convenient, and does not require additional fixing devices and complicated installation steps, if the adhesive ages or fails, it may cause a gap between the heating tape and the surface of the gas distribution plate, affecting the heating effect. The method of fixing with bolts and other fixing methods is more complicated and not conducive to disassembly and maintenance. Utility Model Content
