वाल्व्हused for fluid control, from the simplest shut-off झडप to the various झडपs used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the झडप ranges from extremely small instrument झडपs to large diameters up to 10m. वाल्व्हfor industrial pipelines. दझडप 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. दworking pressure of the झडप 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℃. दझडप 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. दझडप 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.
दpurpose of the झडप दझडप 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 झडप has the following purposes: 1. Cut-off झडप: connect or cut off the medium in each section of the pipeline. Such as gate झडप, globe झडप, ball झडप, plug झडप, diaphragm झडप, butterfly झडप, etc. 2 Regulating झडपs: Regulate the flow and pressure of the medium in the pipeline. Such as throttle झडप, regulating झडप, pressure reducing झडप, safety झडप, etc. 3 Shunt झडप: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution झडपs, three-way plug झडपs, three-way or four-way ball झडपs, traps, etc. Valve classification There are many types of झडपs. With the continuous improvement of the process and performance of various complete sets of equipment, the types of झडपs are still increasing, but in general they can be divided into two categories: automatic झडपs rely on media (liquid, gas, Steam, etc.) a झडप that operates on its own. Such as safety झडपs, check झडपs, pressure reducing झडपs, traps, hydraulic control झडपs, emergency shut-off झडपs, exhaust झडपs, etc.
