Site keywords: Angle regulator; Reverse use ( Installation) ; Small open degree; Easy to destroy half automation control system in produce process, the control valve is a matter, will be the necessary link, called process produces semi-automatic 'hands', is one of the semi-automatic stem end stem system components. When adjusting valve reverse, both along to close the valve core in the direction of fluid flow, the regulator will increase the flow of experience. Occasions only in high-pressure differential and high viscosity, easy to coke, medium of suspended particulate matter what situation, to introduce the reverse installation, namely material side in bottom out. 3, that ordinary things, Angle regulator are introduced reverse use, only in high pressure, high viscosity, easy to coke and application of medium containing suspended particles to introduce the reverse. 。 From the dynamic point of view, water regulating valve is a part of the throttling element can change of the resistance, regulating valve is in accordance with the input signal through the change schedule to change resistance coefficient, thus achieve the purpose of the flow adjustment. When the regulator change flow direction, because the flow changes moved) The value change. And under the condition of normal process, adjusting valve opening is modest, even if small open degree is short, so the valve can be normal safe use. It can prevent the coke, bonded and congestion phenomena occur, also easy to clean and self-purification. When water linkage, Angle regulator initiation violent vibration, and send out very harsh noise, test 4 h after the valve core is disconnected. 1. 2 Angle regulator is, reverse comparison ordinary things, Angle regulator is all right and use positive installation, namely the bottom into the side out. Q: Angle regulator is reasonable use of answer: Angle regulator flow is simple, small resistance, ordinary things condition suitable for use in positive use ( Installation) 。 Angle valve reverse use goal is to improve the injustice of the former balance and abrasion loss of valve core, at the same time can also help in high viscosity, easy to coke and the flow of medium of suspended particulate matter, and prevent Marine valve coke and congestion. Especially in the chemical plant producing stage, because of the low load test yield, the default process conditions may soon reach not required, the reverse Angle regulator should be used as possible to prevent a long time to open the small open degree, in case the Angle regulator are destroyed. 1, the Angle regulator structure and utilization. 1 Angle regulator structure Angle regulator in addition to the body for Angle, other structures and single-seat valves are similar, its unique place to vote on its flow is simple, small resistance, especially helpful in high pressure drop, high viscosity, including suspended solids and granular the regulation of fluid things. When foreign senior experts think is caused by the valve core production quality is very bad. 2, Angle valve reverse analytical brought in from the west of jilin chemical industry co. , LTD enterprise acetaldehyde unit, pv - 23404 Angle regulator under the condition of high technology, to introduce the reverse. The authors think that is not quality problem, but because the use is not reasonable. Water linkage, the synthetic process conditions could soon be at normal condition, the regulator in a long time in a small open degree under the condition of use, the utility of unbalanced force because injustice, can reveal severe. It is made up of actuator and valve of two local. Each kind of valve of the normal flow to make the direction of the valve core to open ( Use positive) , production factory can only supply the normal flow of circulation experienced) Values and special nature of the traffic. We know that, so far apart from butterfly valves and diaphragm valve in structure absolutely semmetry, all other structure regulator said is wrong. When reverse use, should prevent small open degree of things under the condition of long period running, especially more attention should be paid to during commissioning. So the regulator will initiation violent vibration and emit a cacophony of noise and thus cause valve core disconnect soon. Below is the disconnect comprised anatomy. But in high pressure drop to introduce Angle regulator reverse use, to improve the injustice, balance and loss of damage to the valve core, at the same time can also help in the flow of the medium, to prevent the regulator and coke and congestion. Angle regulator used in reverse, especially should prevent small open degree is open for a long time of things, in case of valve core from the damage of actuating violent vibration.
