katupadalah komponen kontrol dalam sistem penghantaran fluida perpipaan. Ini digunakan untuk mengubah bagian bagian dan arah aliran medium. Ini memiliki fungsi pengalihan, cutoff, penyesuaian, pelambatan, periksa, pengalihan atau pelepas tekanan luapan.
katupused for fluid control, from the simplest shut-off katup to the various katups used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the katup ranges from extremely small instrument katups to large diameters up to 10m. katupfor industrial pipelines. Itukatup can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. Ituworking pressure of the katup can be from 1.3х10MPa to 1000MPa ultra-high pressure and working temperature From the ultra-low temperature of -269℃ to the high temperature of 1430℃. Itukatup can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic, electromagnetic-hydraulic, electric-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc. ; Under the action of pressure, temperature or other forms of sensing signals, it can act according to the predetermined requirements, or simply open or close without relying on the sensing signals. Itukatup relies on the drive or automatic mechanism to make the opening and closing parts lift and slide Move, swing or rotate, thereby changing the size of the flow channel to achieve its control function.
Itupurpose of the katup Itukatup is a kind of pipeline accessory, it is a device used to change the section of the passage and the flow direction of the medium, and control the movement of the conveying medium. It has diversion, cut-off, adjustment, throttling, check, diversion or overflow Functions such as pressure relief.
Specifically, the katup has the following purposes: 1. Cut-off katup: connect or cut off the medium in each section of the pipeline. Such as gate katup, globe katup, ball katup, plug katup, diaphragm katup, butterfly katup, etc. 2 Regulating katups: Regulate the flow and pressure of the medium in the pipeline. Such as throttle katup, regulating katup, pressure reducing katup, safety katup, etc. 3 Shunt katup: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution katups, three-way plug katups, three-way or four-way ball katups, traps, etc. Valve classification There are many types of katups. With the continuous improvement of the process and performance of various complete sets of equipment, the types of katups are still increasing, but in general they can be divided into two categories: automatic katups rely on media (liquid, gas, Steam, etc.) a katup that operates on its own. Such as safety katups, check katups, pressure reducing katups, traps, hydraulic control katups, emergency shut-off katups, exhaust katups, etc.
