The
kapakboru hattı sıvı taşıma sistemindeki bir kontrol bileşenidir. Ortamın geçiş bölümünü ve akış yönünü değiştirmek için kullanılır. Saptırma, kesme, ayarlama, kısma, kontrol, saptırma veya taşma basıncı tahliye işlevlerine sahiptir.
Vanalarused for fluid control, from the simplest shut-off kapak to the various kapaks used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the kapak ranges from extremely small instrument kapaks to large diameters up to 10m. Vanalarfor industrial pipelines. The kapak 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. The working pressure of the kapak 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℃. The kapak 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. The kapak 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.
The purpose of the kapak The kapak 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 kapak has the following purposes: 1. Cut-off kapak: connect or cut off the medium in each section of the pipeline. Such as gate kapak, globe kapak, ball kapak, plug kapak, diaphragm kapak, butterfly kapak, etc. 2 Regulating kapaks: Regulate the flow and pressure of the medium in the pipeline. Such as throttle kapak, regulating kapak, pressure reducing kapak, safety kapak, etc. 3 Shunt kapak: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution kapaks, three-way plug kapaks, three-way or four-way ball kapaks, traps, etc. Valve classification There are many types of kapaks. With the continuous improvement of the process and performance of various complete sets of equipment, the types of kapaks are still increasing, but in general they can be divided into two categories: automatic kapaks rely on media (liquid, gas, Steam, etc.) a kapak that operates on its own. Such as safety kapaks, check kapaks, pressure reducing kapaks, traps, hydraulic control kapaks, emergency shut-off kapaks, exhaust kapaks, etc.
