Description

Technical Field

[0001] The invention relates to the technical field of sensors, and in particular to a sensor cover of a mass flow meter. Background Art

[0002] Mass flowmeter is a high-precision flow measurement instrument, which is widely used in petroleum, chemical, pharmaceutical, food and other industrial fields. Its core components include measuring tube, vibration drive device and signal detector, etc. The accuracy and stability of these components are crucial to the measurement accuracy of the flowmeter. However, in actual industrial environments, flowmeters often face the challenges of multiple harsh conditions such as corrosion, humidity, high temperature and high pressure, which will seriously affect the performance and life of the flowmeter.

[0003] In order to protect the core components of the flow meter and improve its ability to adapt to harsh environments, researchers have been exploring various effective protection measures. Among them, designing a reasonable and efficient sensor cover has become an important research direction. As the external protection structure of the flow meter, the sensor cover not only needs to have good sealing and structural strength, but also needs to be able to adapt to various complex working environments.

[0004] At present, the mass flow meter sensor cover design technology in the prior art has the following main disadvantages:

[0005] (1) Insufficient sealing: Due to the split design or imperfect sealing technology, there may be gaps in the joints of the existing cover, which makes it easy for external humid gas, corrosive substances or dust to invade, thereby affecting the performance and life of the internal components of the flow meter.

[0006] (2) Insufficient structural strength: Split or multi-component designs may have insufficient structural strength due to loose connections or improper material selection, and may not be able to effectively resist external shocks, vibrations or pressure changes, thus affecting the accuracy and stability of the flow meter.

[0007] (3) High manufacturing cost and installation complexity: Since multiple parts need to be manufactured and assembled, the cover design of the prior art often increases the manufacturing cost and installation complexity, and also increases the difficulty and cost of maintenance.

[0008] (4) Lack of internal environmental control: The existing technology generally does not consider creating a stable, dry, and oxygen-free environment inside the housing to protect the internal components from oxidation, corrosion, or frost, which may cause the performance of the flow meter to deteriorate in harsh environments. Summary of the invention

[0009] The invention provides a mass flow meter sensor cover, aiming to solve the problems in the prior art.

[0023] The beneficial effects of adopting the above further solution are simple structure, reasonable design, and the fixed connection between the lower ends of the two vertical straight tubes and the sensor body is connected by two fastening hoops, which is convenient for assembly.

[0024] Furthermore, the inert gas filled in the space formed by the horizontal straight tube, the two elbows and the two vertical straight tubes is nitrogen.

[0025] The beneficial effects of adopting the above further scheme are simple structure and reasonable design. Inert gas nitrogen is filled into the housing to create a dry, oxygen-free environment. At the same time, by controlling the purity and filling amount of nitrogen, oxidation and corrosion of internal components can be effectively prevented.

[0026] Furthermore, the horizontal straight tube and / or the two elbows and / or the two vertical straight tubes are respectively stainless steel tubes.

[0027] The beneficial effects of adopting the above further solution are simple structure and reasonable design. The horizontal straight pipe, two elbows and two vertical straight pipes are respectively made of stainless steel pipes, which improves the structural strength of the cover shell.

[0078] The working principle of the present invention is as follows:

[0079] An integrated cover structure is used to protect the measuring tube of the flow meter sensor to ensure internal sealing and avoid external damage to it, which would affect the flow meter test performance.

[0080] The cover provided by the present invention has the following advantages:

[0081] (1) Integrated structural design:

[0082] Innovation: Standard stainless steel pipes and elbows are welded into an integral cover, eliminating the gaps in the traditional split design, thereby improving the sealing performance.

[0083] Key point: The overall structural design ensures the integrity and consistency of the cover, effectively preventing the intrusion of external factors such as moisture and corrosion.

[0084] The present invention uses standard stainless steel pipes and elbows for welding to form an integral sensor housing. This integrated design eliminates the connection gap in the traditional split housing, thereby significantly improving the sealing performance. At the same time, the selection of stainless steel materials ensures that the housing has good corrosion resistance and structural strength.

[0085] (2) Sealing technology optimization:

[0086] Innovation: Advanced welding technology and sealing materials are used in the welding process to ensure the sealing and firmness of the weld, and sealing gaskets and fastening devices are added at the interface.

[0087] Key point: The optimized sealing technology significantly improves the protection capability of the cover and ensures the safe operation of the components inside the flow meter.

[0088] In the welding process of the cover shell, the present invention adopts advanced welding technology and sealing materials to ensure the sealing and firmness of the weld. In addition, the interface of the cover shell is provided with a sealing gasket and a fastening device, which further enhances the overall sealing effect.

[0089] (3) Enhanced structural strength:

[0090] Innovation: Through reasonable structural design and material selection, the structural strength of the cover is enhanced, enabling it to withstand external shocks and vibrations.

[0091] Key point: The improvement of structural strength ensures the stability and accuracy of the flow meter in harsh environments.

[0092] In order to improve the structural strength of the housing, the present invention fully considers the parameters such as the wall thickness and curvature radius of the steel pipe and elbow, as well as the overall shape and size of the housing in the design. Through reasonable structural design and material selection, the housing can resist external impact and vibration, ensuring the stable operation of the flow meter.

[0093] (4) Internal environment control:

[0094] Innovation: Inert gas nitrogen is filled inside the cover to create a dry, oxygen-free environment, and temperature and humidity sensors are set up for real-time monitoring and external control.

[0095] Key point: The introduction of internal environmental control technology effectively extends the service life of the flow meter and improves its performance stability in various working environments.

[0096] The present invention fills the interior of the housing with inert gas nitrogen to create a dry, oxygen-free environment. By controlling the purity and filling amount of nitrogen, oxidation and corrosion of internal components can be effectively prevented. At the same time, temperature and humidity sensors are also provided inside the housing to monitor changes in the internal environment in real time, and are adjusted through external control devices to ensure the performance and stability of the flow meter under various working environments.
