клапанқұбырөткізгішті тасымалдау жүйесіндегі басқару компоненті болып табылады. Ол ортаның өту бөлігін және ағым бағытын өзгерту үшін қолданылады. Оның бағытын өзгерту, тоқтату, реттеу, дроссельдеу, тексеру, бұру немесе асып кету қысымын төмендету функциялары бар.
Клапандарused for fluid control, from the simplest shut-off клапан to the various клапанs used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the клапан ranges from extremely small instrument клапанs to large diameters up to 10m. Клапандарfor industrial pipelines. Theклапан 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. Theworking pressure of the клапан 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℃. Theклапан 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. Theклапан 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.
Thepurpose of the клапан Theклапан 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 клапан has the following purposes: 1. Cut-off клапан: connect or cut off the medium in each section of the pipeline. Such as gate клапан, globe клапан, ball клапан, plug клапан, diaphragm клапан, butterfly клапан, etc. 2 Regulating клапанs: Regulate the flow and pressure of the medium in the pipeline. Such as throttle клапан, regulating клапан, pressure reducing клапан, safety клапан, etc. 3 Shunt клапан: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution клапанs, three-way plug клапанs, three-way or four-way ball клапанs, traps, etc. Valve classification There are many types of клапанs. With the continuous improvement of the process and performance of various complete sets of equipment, the types of клапанs are still increasing, but in general they can be divided into two categories: automatic клапанs rely on media (liquid, gas, Steam, etc.) a клапан that operates on its own. Such as safety клапанs, check клапанs, pressure reducing клапанs, traps, hydraulic control клапанs, emergency shut-off клапанs, exhaust клапанs, etc.
