The initial seal preload is individually adjustable by preloading the screws
The processing double-cone sealing structure is simple, and the main machining methods include vertical lathe, drilling and tapping, which is easy to manufacture and the processing precision is not too high. The threaded sleeve and the top cover of the externally threaded plug are required to have high precision in the process of interrupting the thread. The large-sized insert is required, and the large-diameter sawtooth thread is difficult to process, especially after the cylinder thread is damaged. When processing the D-bolt seal structure, it is only necessary to position the screw holes of the top cover and the end of the cylinder at one time to complete the drilling and tapping; the D-bolt is also simple to manufacture; the machining accuracy of the C-ring or O-ring The requirements are higher. Sealing reliability utilizes internal pressure to create a self-tightening action, which is a simple and effective way to improve the sealing effect. For the double cone seal structure, the cylindrical surface of the top cover is milled with a longitudinal groove. When pre-tightening, the top bolt is pressed by the main bolt to press the double cone ring, and the inner side surface is tightly attached to the top cover to establish an initial seal; during operation, the medium pressure enters the gap between the double cone ring and the top cover, so that the double cone ring Radial expansion, thus playing a radial self-tightening effect. Once the structure leaks during operation, tightening the bolts is useless. For the Kazari seal, after tightening the pre-tightening bolt, the pressure ring presses the gasket to make it close to the top cover and the end of the cylinder and establish an initial seal; during the operation, if the pre-tightening bolt is loose or leaking , you can continue to tighten the pre-tightening bolts, so the seal is reliable. The D-bolt high-pressure sealing structure adopts elastic wire contact sealing gasket (such as C-ring, etc.), and the initial sealing is realized by pre-tightening screws, and the pre-tightening degree is separately adjustable. Water level sensor, alose called hydrostatic pressure level sensors, submersible level sensors, which are submersible level sensors used for measuring the level of liquids (including corrosive liquids) in deep tanks or water in reservoirs. It provide accuracy and reliability across a wide range of applications. Based on the principle that the measured liquid static pressure is proportional to the height of the liquid, the advanced isolation type diffusion silicon sensor or ceramic capacitive Pressure Sensor is used to convert the static pressure into electrical signals, and then through temperature compensation and linear correction, into standard electrical signals (generally 4-20mA/1-5VDC). water tank level sensor, pressure level sensor, submersible level sensor, hydrostatic level sensor, water Level Transmitter Xi'an Gavin Electronic Technology Co., Ltd , https://www.gamicos-meas.com
