klapanboru kəməri maye ötürmə sistemindəki bir nəzarət komponentidir. Keçid hissəsini və mühitin axın istiqamətini dəyişdirmək üçün istifadə olunur. Burulma, kəsmə, tənzimləmə, boğma, yoxlama, kənarlaşdırma və ya daşqın təzyiqinin azaldılması funksiyalarına malikdir.
Vanalarused for fluid control, from the simplest shut-off klapan to the various klapans used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the klapan ranges from extremely small instrument klapans to large diameters up to 10m. Vanalarfor industrial pipelines. Theklapan 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 klapan 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℃. Theklapan 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. Theklapan 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 klapan Theklapan 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 klapan has the following purposes: 1. Cut-off klapan: connect or cut off the medium in each section of the pipeline. Such as gate klapan, globe klapan, ball klapan, plug klapan, diaphragm klapan, butterfly klapan, etc. 2 Regulating klapans: Regulate the flow and pressure of the medium in the pipeline. Such as throttle klapan, regulating klapan, pressure reducing klapan, safety klapan, etc. 3 Shunt klapan: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution klapans, three-way plug klapans, three-way or four-way ball klapans, traps, etc. Valve classification There are many types of klapans. With the continuous improvement of the process and performance of various complete sets of equipment, the types of klapans are still increasing, but in general they can be divided into two categories: automatic klapans rely on media (liquid, gas, Steam, etc.) a klapan that operates on its own. Such as safety klapans, check klapans, pressure reducing klapans, traps, hydraulic control klapans, emergency shut-off klapans, exhaust klapans, etc.
