バルブパイプライン流体搬送システムの制御コンポーネントです。媒体の通過部と流れ方向を変えるために使用します。迂回、カットオフ、調整、スロットル、チェック、迂回、またはオーバーフロー圧力解放の機能があります。
バルブused for fluid control, from the simplest shut-off バルブ to the various バルブs used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the バルブ ranges from extremely small instrument バルブs to large diameters up to 10m. バルブfor industrial pipelines. ザ・バルブ 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. ザ・working pressure of the バルブ 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℃. ザ・バルブ 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. ザ・バルブ 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.
ザ・purpose of the バルブ ザ・バルブ 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 バルブ has the following purposes: 1. Cut-off バルブ: connect or cut off the medium in each section of the pipeline. Such as gate バルブ, globe バルブ, ball バルブ, plug バルブ, diaphragm バルブ, butterfly バルブ, etc. 2 Regulating バルブs: Regulate the flow and pressure of the medium in the pipeline. Such as throttle バルブ, regulating バルブ, pressure reducing バルブ, safety バルブ, etc. 3 Shunt バルブ: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution バルブs, three-way plug バルブs, three-way or four-way ball バルブs, traps, etc. Valve classification There are many types of バルブs. With the continuous improvement of the process and performance of various complete sets of equipment, the types of バルブs are still increasing, but in general they can be divided into two categories: automatic バルブs rely on media (liquid, gas, Steam, etc.) a バルブ that operates on its own. Such as safety バルブs, check バルブs, pressure reducing バルブs, traps, hydraulic control バルブs, emergency shut-off バルブs, exhaust バルブs, etc.
