Steel framework regulating: types, parameters, appointment

<div> <div id="article_body" itemprop="articleBody"> <p> Steel framework regulating a wide list of functional structures for flow distribution and overlap of working fluid media, the regulation of the parameters of individual processes.In particular, changing the pressure, temperature, pressure, number of submitted materials is done by changing the flow rate of the conveyed fluid.Mounted control valves in piping systems, vessels and units that require distribution of a trip or use transoprtiruemyh environments.</p> <h2> main types of valves </h2> <p> </p> <ol> <li> Steel framework regulating - the main purpose of the regulation aims to set parameters of working environments.It includes all kinds of valves, balancing and reducing character.</li> <li> Valves - used to stop the flow by moving working environments.Among the most common types of valves should be highlighted: the gates to shut off the flow of liquids, ball valves, gate valves wedge-shaped valves.</li> </ol> <h2> elements </h2> <p> control valves Steel framework regulating functions on the basis of the following elements: </p> <div class="mid-g-block"> </div> <ul> <li> control valves;</li> <li> mixing valves;</li> <li> control valves;</li> <li> pressure regulators direct action.</li> </ul> <div><center> <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> <!-- tipings --> <ins class="adsbygoogle" style="display:inline-block;width:336px;height:280px" data-ad-client="ca-pub-4235477045164216" data-ad-slot="4216162687"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> </center></div> <h2> Appointment </h2> <p> </p> <p> Control valves are used to support the necessary, set values ​​of certain processes by regulating the flow of specific working environments.</p> <p> According to the construction, fitting of a regulatory nature is practically indistinguishable from the stop.In some systems, the same control valves can be used for its intended purpose and as a stop.</p> <div class="mid-g-block"> </div> <h2> Varieties control valves </h2> <p> </p> <ol> <li> Fotorazdelitelnaya - used when the need to separate work environments that are in various states.</li> <li> condensation - is used to remove condensate, a limited pass or shut off the flow of superheated steam.</li> <li> Safety Valves - directed to the automatic protection of pipelines and equipment from unexpected or unacceptable changes in the operation of the pipeline system.</li> <li> control - is designed to control the receipt of working environments in measuring and control instruments.</li> <li> Mixing and Distribution - distributes separate working fluid flow in different directions either directly involved, if necessary mixing them.</li> <li> throttling - is used, if necessary, reduce the fluid pressure in systems that operate under substantial pressure spikes.</li> <li> transience - the reverse fixture in which the possible forced open, restriction or closing stroke.</li> </ol> <h2> Features selection </h2> <p> </p> <p> Since in most cases the level of reliability and durability of the valve depends on efficiency, high stability of the entire pipeline system, the most important thing is her choice.We should pay attention not to the following points: </p> <ol> <li> picks adjustable fittings shall determine on the basis of operating conditions: the nature of the working environment, temperature, pressure indicators in the system.</li> <li> important when choosing a control valve is to match the characteristics of the nominal size of its passage.</li> <li> Before inclined to purchase reinforcement, it is necessary to clarify the method of control: remote, manual, on the basis of electric, hydraulic or pneumatic actuator.</li> <li> initially is to determine the material of construction of the body: cast iron, corrosion resistant steel, bronze and others.</li> <li> Sold fittings depending on the purpose of separate elements: an adjustable or safety valve, valve, valve.</li> <li> are important geometric parameters that differ regulating valves: length, height, flange types, sizes and number of bolts like.</li> <li> times must verify compliance with the characteristics and parameters of the selected fixtures to specified requirements and operating conditions of the pipeline system.</li> </ol> </div> </div>
