Description

Technical Field

[0001] This utility model specifically relates to a wear-resistant Pitot tube. Background Technology

[0002] After a period of operation, the VPT sampling pitot tubes for CFB ultra-low emission systems may experience corrosion and air leakage. In severe cases, this can significantly interfere with the flow rate, pressure, and temperature parameters of the operating CEMS system, thereby affecting the accuracy and timeliness of environmental data transmission from the operating unit. Therefore, during each unit shutdown and maintenance, maintenance personnel will promptly and thoroughly inspect the VPT sampling devices for corrosion and air leakage, which impacts the power plant's operational efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a wear-resistant Pitot tube to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant Pitot tube, comprising:

[0005] Pitot tube, one end of which is connected to a flange, and a protective component is provided at the connection between the pitot tube and the flange to extend the service life of the pitot tube.

[0006] Preferably, the protective component includes, from the outside to the inside, a reinforcing layer for enhanced protection, an adsorption element for assisting in fixing the reinforcing layer, and an adsorption layer for initial protection.

[0007] Preferably, the adsorption layer is laid at the connection between the Pitot tube and the flange, the adsorption element is fixed on the adsorption layer, and the reinforcement layer is laid on the adsorption element.

[0008] Preferably, the adsorption layer is an epoxy resin layer.

[0009] Preferably, the absorbent element is a strip of cotton cloth.

[0010] Preferably, the reinforcing layer is an epoxy resin layer.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The adsorption layer is laid at the connection between the Pitot tube and the flange to provide initial protection for the Pitot tube. At the same time, the adsorption layer increases the surface roughness of the Pitot tube, which facilitates the installation of the adsorption component. After the adsorption component is installed, it further assists in fixing the reinforcement layer that strengthens the protection, thereby increasing the corrosion resistance and service life of the Pitot tube.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-2 The present invention provides a technical solution: a wear-resistant pitot tube, comprising:

[0018] Pitot tube 1, one end of which is connected to flange 5, and a protective component for extending the service life of Pitot tube 1 is provided at the connection between Pitot tube 1 and flange 5.

[0019] In this embodiment, the protective component includes, from the outside to the inside, a reinforcing layer 4 for enhanced protection, an adsorption element 3 for assisting in fixing the reinforcing layer 4, and an adsorption layer 2 for initial protection.

[0020] In this embodiment, the adsorption layer 2 is laid at the connection between the Pitot tube 1 and the flange 5, the adsorption element 3 is fixed on the adsorption layer 2, and the reinforcing layer 4 is laid on the adsorption element 3.

[0021] The adsorption layer 2 is laid at the connection between Pitot tube 1 and flange 5 to provide initial protection for Pitot tube 1. At the same time, the adsorption layer 2 increases the surface roughness of Pitot tube 1, which is conducive to the installation of adsorption component 3. After the adsorption component 3 is installed, the reinforcement layer 4 is further used to strengthen the protection, thereby increasing the corrosion resistance and service life of Pitot tube 1.

[0022] In this embodiment, the adsorption layer 2 is an epoxy resin layer. Epoxy resin liquid is applied to form an epoxy resin layer. The length of the epoxy resin layer is generally 30cm, and the thickness is 1cm. The temperature at the connection between the Pitot tube 1 and the flange 5 is generally 50℃, making the epoxy resin layer more robust. That is, the epoxy resin layer provides initial protection at the connection. Furthermore, the adsorption layer 2 roughens the surface of the Pitot tube 1, increasing the friction of the Pitot tube 1 surface, which is beneficial for the subsequent installation of the adsorption component and the laying of the reinforcement layer 4.

[0023] In this embodiment, the adsorption element 3 is a cotton strip. Before the epoxy resin of the adsorption layer 2 cools down, the cotton strip is evenly wrapped around it so that the adsorption element 3 is also fixed on the Pitot tube 1.

[0024] In this embodiment, the reinforcing layer 4 is an epoxy resin layer. The epoxy resin is applied evenly again on the cotton strip, and after waiting for 30 minutes, it cools into a solid state to complete the process.

[0025] The working principle and usage process of this invention are as follows: Apply epoxy resin evenly at 30cm from the VPT Pitot tube connection flange. While the epoxy resin is still warm, wrap cotton strips evenly around it. Then, apply epoxy resin evenly again to the cotton strips. Wait 30 minutes for it to cool and solidify, and a wear-resistant Pitot tube will be formed.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
