injapadalah komponen kawalan dalam sistem penyampaian cecair saluran paip. Ia digunakan untuk mengubah bahagian laluan dan arah aliran medium. Ia memiliki fungsi pengalihan, pemotongan, penyesuaian, pendikit, periksa, pengalihan atau pelepasan tekanan limpahan.
Injapused for fluid control, from the simplest shut-off injap to the various injaps used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the injap ranges from extremely small instrument injaps to large diameters up to 10m. Injapfor industrial pipelines. Theinjap 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 injap 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℃. Theinjap 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. Theinjap 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 injap Theinjap 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 injap has the following purposes: 1. Cut-off injap: connect or cut off the medium in each section of the pipeline. Such as gate injap, globe injap, ball injap, plug injap, diaphragm injap, butterfly injap, etc. 2 Regulating injaps: Regulate the flow and pressure of the medium in the pipeline. Such as throttle injap, regulating injap, pressure reducing injap, safety injap, etc. 3 Shunt injap: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution injaps, three-way plug injaps, three-way or four-way ball injaps, traps, etc. Valve classification There are many types of injaps. With the continuous improvement of the process and performance of various complete sets of equipment, the types of injaps are still increasing, but in general they can be divided into two categories: automatic injaps rely on media (liquid, gas, Steam, etc.) a injap that operates on its own. Such as safety injaps, check injaps, pressure reducing injaps, traps, hydraulic control injaps, emergency shut-off injaps, exhaust injaps, etc.
