balbulaay isang bahagi ng kontrol sa pipeline fluid conveying system. Ginagamit ito upang baguhin ang seksyon ng daanan at ang direksyon ng daloy ng daluyan. Mayroon itong mga pag-andar ng paglihis, cutoff, pagsasaayos, throttling, tseke, paglihis o pag-overflow ng presyon ng presyon.
Mga balbulaused for fluid control, from the simplest shut-off balbula to the various balbulas used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the balbula ranges from extremely small instrument balbulas to large diameters up to 10m. Mga balbulafor industrial pipelines. Angbalbula 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. Angworking pressure of the balbula 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℃. Angbalbula 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. Angbalbula 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.
Angpurpose of the balbula Angbalbula 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 balbula has the following purposes: 1. Cut-off balbula: connect or cut off the medium in each section of the pipeline. Such as gate balbula, globe balbula, ball balbula, plug balbula, diaphragm balbula, butterfly balbula, etc. 2 Regulating balbulas: Regulate the flow and pressure of the medium in the pipeline. Such as throttle balbula, regulating balbula, pressure reducing balbula, safety balbula, etc. 3 Shunt balbula: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution balbulas, three-way plug balbulas, three-way or four-way ball balbulas, traps, etc. Valve classification There are many types of balbulas. With the continuous improvement of the process and performance of various complete sets of equipment, the types of balbulas are still increasing, but in general they can be divided into two categories: automatic balbulas rely on media (liquid, gas, Steam, etc.) a balbula that operates on its own. Such as safety balbulas, check balbulas, pressure reducing balbulas, traps, hydraulic control balbulas, emergency shut-off balbulas, exhaust balbulas, etc.
