판막파이프라인 유체 이송 시스템의 제어 구성 요소입니다. 매체의 통과 단면 및 흐름 방향을 변경하는 데 사용됩니다. 전환, 차단, 조정, 조절, 확인, 전환 또는 오버플로 압력 릴리프 기능이 있습니다.
밸브used for fluid control, from the simplest shut-off 판막 to the various 판막s used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the 판막 ranges from extremely small instrument 판막s to large diameters up to 10m. 밸브for industrial pipelines. 그만큼판막 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. 그만큼working pressure of the 판막 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℃. 그만큼판막 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. 그만큼판막 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.
그만큼purpose of the 판막 그만큼판막 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 판막 has the following purposes: 1. Cut-off 판막: connect or cut off the medium in each section of the pipeline. Such as gate 판막, globe 판막, ball 판막, plug 판막, diaphragm 판막, butterfly 판막, etc. 2 Regulating 판막s: Regulate the flow and pressure of the medium in the pipeline. Such as throttle 판막, regulating 판막, pressure reducing 판막, safety 판막, etc. 3 Shunt 판막: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution 판막s, three-way plug 판막s, three-way or four-way ball 판막s, traps, etc. Valve classification There are many types of 판막s. With the continuous improvement of the process and performance of various complete sets of equipment, the types of 판막s are still increasing, but in general they can be divided into two categories: automatic 판막s rely on media (liquid, gas, Steam, etc.) a 판막 that operates on its own. Such as safety 판막s, check 판막s, pressure reducing 판막s, traps, hydraulic control 판막s, emergency shut-off 판막s, exhaust 판막s, etc.
