De
klepis een besturingscomponent in het vloeistoftransportsysteem van de pijpleiding. Het wordt gebruikt om de doorgangssectie en de stroomrichting van het medium te veranderen. Het heeft de functies van omleiding, afsluiting, aanpassing, smoren, controle, omleiding of overloopdrukontlasting.
Kleppenused for fluid control, from the simplest shut-off klep to the various kleps used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the klep ranges from extremely small instrument kleps to large diameters up to 10m. Kleppenfor industrial pipelines. Deklep 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. Deworking pressure of the klep 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℃. Deklep 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. Deklep 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.
Depurpose of the klep Deklep 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 klep has the following purposes: 1. Cut-off klep: connect or cut off the medium in each section of the pipeline. Such as gate klep, globe klep, ball klep, plug klep, diaphragm klep, butterfly klep, etc. 2 Regulating kleps: Regulate the flow and pressure of the medium in the pipeline. Such as throttle klep, regulating klep, pressure reducing klep, safety klep, etc. 3 Shunt klep: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution kleps, three-way plug kleps, three-way or four-way ball kleps, traps, etc. Valve classification There are many types of kleps. With the continuous improvement of the process and performance of various complete sets of equipment, the types of kleps are still increasing, but in general they can be divided into two categories: automatic kleps rely on media (liquid, gas, Steam, etc.) a klep that operates on its own. Such as safety kleps, check kleps, pressure reducing kleps, traps, hydraulic control kleps, emergency shut-off kleps, exhaust kleps, etc.
