The
شیر فلکهیک م controlلفه کنترل در سیستم انتقال مایعات خط لوله است. برای تغییر قسمت عبور و جهت جریان محیط استفاده می شود. این توابع انحراف ، قطع ، تنظیم ، گاز ، کنترل ، انحراف یا کاهش فشار سرریز است.
شیرآلاتused for fluid control, from the simplest shut-off شیر فلکه to the various شیر فلکهs used in extremely complex automatic control systems, have a wide range of varieties and specifications, and the nominal diameter of the شیر فلکه ranges from extremely small instrument شیر فلکهs to large diameters up to 10m. شیرآلاتfor industrial pipelines. The شیر فلکه 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. The working pressure of the شیر فلکه 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℃. The شیر فلکه 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. The شیر فلکه 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.
The purpose of the شیر فلکه The شیر فلکه 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 شیر فلکه has the following purposes: 1. Cut-off شیر فلکه: connect or cut off the medium in each section of the pipeline. Such as gate شیر فلکه, globe شیر فلکه, ball شیر فلکه, plug شیر فلکه, diaphragm شیر فلکه, butterfly شیر فلکه, etc. 2 Regulating شیر فلکهs: Regulate the flow and pressure of the medium in the pipeline. Such as throttle شیر فلکه, regulating شیر فلکه, pressure reducing شیر فلکه, safety شیر فلکه, etc. 3 Shunt شیر فلکه: change the flow direction of the medium in the pipeline, used to distribute, separate or mix the medium. Such as distribution شیر فلکهs, three-way plug شیر فلکهs, three-way or four-way ball شیر فلکهs, traps, etc. Valve classification There are many types of شیر فلکهs. With the continuous improvement of the process and performance of various complete sets of equipment, the types of شیر فلکهs are still increasing, but in general they can be divided into two categories: automatic شیر فلکهs rely on media (liquid, gas, Steam, etc.) a شیر فلکه that operates on its own. Such as safety شیر فلکهs, check شیر فلکهs, pressure reducing شیر فلکهs, traps, hydraulic control شیر فلکهs, emergency shut-off شیر فلکهs, exhaust شیر فلکهs, etc.
