Ħarsa ġenerali tal-valv tal-farfett pnewmatiku, valv tal-farfett pnewmatiku huwa magħmul minn attwatur pnewmatiku u valv tal-farfett. Il-valv tal-farfett pnewmatiku juża pjanċa tal-farfett ċirkolari li tinbidel biż-zokk tal-valv biex tiftaħ u tagħlaq. Il-valv pnewmatiku biex tlesti l-azzjoni ta 'attivazzjoni huwa prinċipalment użat bħala valv -off, u jista' wkoll ikun iddisinjat biex ikollu l-effett ta 'dispaċċ jew valv ta' sezzjoni u dispaċċ. Fil-preżent, il-valv tal-farfett huwa taħt pressjoni għolja. L-użu ta 'pajpijiet ta' dijametru kbir u medju qed jiżdied. Klassifikazzjoni tal-valv tal-farfett pnewmatiku, valv tal-farfett pnewmatiku tal-istainless steel, valv tal-farfett pnewmatiku tas-siġillar iebes valv tal-farfett pnewmatiku tas-siġillar artab, valv tal-farfett pnewmatiku tal-azzar tal-karbonju.
Il-prinċipju tax-xogħol tal-valv tal-farfett pnewmatiku huwa magħmul mill-attwatur pnewmatiku u l-konnessjoni tal-valv tal-farfett. Il-valv tal-farfett pnewmatiku huwa mmexxi mill-arja kkompressata fl-attwatur pnewmatiku biex issuq il-pjanċa tal-farfett ċirkolari biex tagħmel moviment ta 'rotazzjoni ta' 90 grad, li jintuża bħala swiċċ tal-pipeline u fluss li jirregola. Il-valv tal-farfett pnewmatiku jinfetaħ u jingħalaq permezz ta '0-90 grad bħala l-prinċipju tax-xogħol. Jiġifieri, 0 gradi huwa l-istat kompletament magħluq, u 90 grad huwa l-istat kompletament miftuħ. Żid positioner mal-attwatur pnewmatiku u daħħal is-sinjal korrispondenti, u l-pjanċa tal-valv tal-farfett tista 'tiġi aġġustata b'mod arbitrarju minn 0 sa 90 grad. L-attwatur tal-valv tal-farfett tal-wejfer pnewmatiku huwa mezz li jirċievi informazzjoni ta 'kontroll u japplika effetti ta' kontroll għal oġġetti kkontrollati f'għodod tekniċi awtomatizzati. L-attwaturi huma kklassifikati f'attwaturi pnewmatiċi, elettriċi u idrawliċi skont l-enerġija tas-sewqan użata. Attwaturi elettriċi u attwaturi pnewmatiċi huma l-attwaturi mainstream kurrenti.
Pneumatic butterfly valve adopts the new series GT type pneumatic actuator, with double effect type and single effect type (spring reset), gear transmission, safe and reliable; large diameter valve adopts series AW type pneumatic actuator fork type transmission, reasonable structure, output Large torque, there are double-effect type and single-effect type. Pneumatic butterfly valve gear type double piston, large output torque and small volume. The cylinder is made of aluminum and gold material, which is light in weight and beautiful in appearance. Manually operated tissue can be installed on top and bottom.
Għas-sistema tat-trab tal-valv tal-farfett pnewmatiku, hemm fatturi oħra li jeħtieġ li jiġu kkunsidrati, bħal: meta l-materjal jitqiegħed fit-tròli minn fuq, ma jistax jiġi mgħaġġel direttament lejn il-pjanċa tal-valv tal-valv (din il-forza tal-impatt se jagħmel ukoll il-valv ma jkunx jista 'jagħlaq sewwa), u l-materjal Il-pressjoni statika tal-valv jeħtieġ ukoll li ma taqbiżx il-pressjoni tal-ġarr iddisinjata tal-valv tal-farfett pnewmatiku, eċċ.
The difference between the control valve and the general manual valve is that it cannot be regarded as an isolated component, but needs to be considered as part of the entire automatic control system. Many problems in the use of the control valve are not the selection and The problem of equipment is due to the lack of user's knowledge of the control valve, which causes the control valve to fail to debug and cooperate with the control system. As long as you know the key point of the problem, select the valve correctly, and debug the control valve in the system debugging stage, the failure rate will be greatly reduced, and the automatic control system will run stably for a long time.
