Glass tube level gauge how to clean dirt and maintenance

Glass tube level gauge how to clean the dirt and maintenance of glass tube level meter Generally, the acid and alkali agent neutralizing washing tap water or distilled water should be taken into account when considering the wetted material. This medium must be used for antisepsis. If no remote transmission is required, no power is needed. The glass tube level gauge is a contact level measurement. But if you want to remotely send a device that requires power, it's usually a flange connection. If the on-site conditions allow it, it's not too much trouble. The biggest advantage is that it looks intuitive, and some other volatile media require an explosion proof level measurement. Medium, with magnetic flap is not bad. The glass tube level gauge device must be vertical. The ball valve should be installed between the glass tube level gauge and the container guide tube to facilitate inspection and cleaning. The position of the glass tube level gauge should be avoided or kept away from the material media entrance and exit. The rapid change of the local area of ​​the material fluid affects the accuracy of the liquid level measurement; the medium should not contain solid impurities or magnetic substances, so as to avoid jamming of the float; before use, the magnetic steel should be used to reduce the size of the sub zero The ball is set to red, and the other balls are set to white; open the bottom flange and install the magnetic float (Note: The heavy end with magnetic end up, can not flip. Commissioning should first open the upper guide valve, and then slowly open the lower valve, Allow the medium to enter the glass tube smoothly (should prevent the medium from impacting the float rapidly during operation, causing fluctuation of the float series and affecting the display accuracy). Observe whether the magnetic red-white ball flips properly, then close the lower-inlet valve, open the drain valve, and let the glass tube fluid The position drops, and the operation is performed three times according to this method. It is normal and it can be put into operation (except for corrosive and other special liquids).
To some extent, the structure of the glass tube level gauge is related to its quality and range of use. In fact, the glass tube level gauge is a measurement tool suitable for on-site inspection. The structural characteristics can be described as follows:
Steel balls are installed in the upper and lower valves. When the glass tube is destroyed by an accident, the steel balls are automatically sealed under the pressure of the container to prevent the liquid in the container from continuing to flow out. The needle valve at the upper end of the level gauge is equipped with a block screw for deflation and the lower needle valve is also equipped with a block screw. The upper and lower valves of the liquid level gauge are equipped with flange joints, which are connected to the container to form a connector, and directly indicate the level of the container Bush through the glass tube. The "jacketed type" has a heating or cooling device. The glass tube level gauge can be used when heating steam, circulating water can be used when cooling, this can adjust the flow performance, jacket type connector size ZG1/4'' internal thread.
Then the maintenance of the glass tube level meter is also very important, mainly including the following three points:
1. Check the level gauge in use regularly. Clean the dirt inside and outside the glass to make the liquid clear.
2. In order to ensure that the tablet is more dense than planned, the medium pressure in the container should be greater than 0.2 MPa. When opening the upper and lower valves, the valve stem should not be less than 4 turns in the exit rotation (when the steel ball seals the door, it will not touch the stem. top.)
3. The two flange ends of the container connected with the liquid level gauge of the glass tube should be ensured in the same vertical plane, otherwise the valve is bent after the installation of the liquid level gauge, so that the glass tube is broken.
Through the explanation of the above information, even a layman will know a little about the level gauge of the glass tube. It is important not only to use it, but also to maintain regularly!
