soupapeest un composant de contrôle dans le système de transport de fluide par pipeline. Il permet de modifier la section de passage et le sens d'écoulement du fluide. Il a les fonctions de déviation, de coupure, de réglage, d'étranglement, de contrôle, de déviation ou de décharge de pression.
Vannesused for fluid control, from the simplest shut-off soupape to the various soupapes used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the soupape ranges from extremely small instrument soupapes to large diameters up to 10m. Vannesfor industrial pipelines. lesoupape 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. leworking pressure of the soupape 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℃. lesoupape 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. lesoupape 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.
lepurpose of the soupape lesoupape 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 soupape has the following purposes: 1. Cut-off soupape: connect or cut off the medium in each section of the pipeline. Such as gate soupape, globe soupape, ball soupape, plug soupape, diaphragm soupape, butterfly soupape, etc. 2 Regulating soupapes: Regulate the flow and pressure of the medium in the pipeline. Such as throttle soupape, regulating soupape, pressure reducing soupape, safety soupape, etc. 3 Shunt soupape: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution soupapes, three-way plug soupapes, three-way or four-way ball soupapes, traps, etc. Valve classification There are many types of soupapes. With the continuous improvement of the process and performance of various complete sets of equipment, the types of soupapes are still increasing, but in general they can be divided into two categories: automatic soupapes rely on media (liquid, gas, Steam, etc.) a soupape that operates on its own. Such as safety soupapes, check soupapes, pressure reducing soupapes, traps, hydraulic control soupapes, emergency shut-off soupapes, exhaust soupapes, etc.
