Iivalvu zeentlobo ezahlukeneyoziinxalenye zolawulo kwiinkqubo zokuhambisa ulwelo, ezisetyenziswa kakhulu ukuvula nokuvala imibhobho, ukulawula indlela yokuhamba, kunye nokulawula iiparameter zesixhobo sokuhambisa (ezifana nobushushu, uxinzelelo, kunye nokuhamba).
Ngokuyintloko iintlobo ezi-8 zeeValve zemarike kunye nePipeline
Iivalvu zeBhola
Aivalvu yebholainokumelana nolwelo okuncinci phakathi kwazo zonkeiintlobo zeevalvu, kwaye nevalvu yebhola encitshisiweyo inokumelana nolwelo okuncinci. Inxalenye yokuvula nokuvala yevalvu yebhola yingqukuva enomngxuma, ejikeleza i-axis ethe nkqo kwitshaneli ukuze kufezekiswe injongo yokuvula nokuvala itshaneli.
Ikota-turnIivalvu zeBhola ezineendlela ezimbinizezona zivali zolawulo lwenkqubo zixhaphakileyo. Ziivali ezineendlela ezimbini (ukungena kunye nokuphuma), ezineendawo ezimbini (ezivulekileyo nezivaliweyo) ezisetyenziselwa ukuvala okanye ukwahlukanisa iinkqubo, iisekethe okanye izinto ezingaphakathi kwenkqubo.
Iivalvu zePlug
Iplagi yevalvu yevalvu yeplagi idla ngokuba yi-cylindrical okanye i-conical, kwaye imilo yetshaneli ingaba yi-rectangular okanye i-trapezoidal njengoko kufuneka. Le valve inesakhiwo esilula, itshintsha ngokukhawuleza, ukumelana nolwelo oluphantsi, kwaye kulula ukuyiqhelanisa nezakhiwo ezinemijelo emininzi.
Iivalvu zeplagi zihlala zisetyenziselwa ukusika nokudibanisa imidiya, kunye nokuguqula ukuhamba, kodwa zinokusetyenziselwa ukubhoboza. Ekubeni umzimba weplagi yevalvu yeplagi ujikeleza kunye nesiqu sevalvu ukufezekisa isenzo sokuvula nokuvala, ingasetyenziselwa nemidiya eneziqwenga ezixhonyiweyo.
Ivalvu yebhabhathane
Iivalvu yebhabhathaneyivalvu yokulawula ukuhamba kwamanzi eqhelekileyo. Umgaqo wayo osebenzayo kukulawula ukuhamba kolwelo ngokulungisa indawo yebhabhathane. Xa ibhabhathane lijikeleza, ulwelo lutshintsha indawo yalo ngebhabhathane, ngaloo ndlela lutshintsha ubukhulu bokuhamba kwamanzi.
Idiski yevalvu ijikeleza i-90° ngaphakathi komgama wesihlalo sevalvu ukuze ivuleke kwaye ivalwe.
Ivalvu yeSango
Inxalenye yokuvula neyokuvala yeivalvu yesangoyisango. Icala lokuhamba kwesango lithe nkqo kwicala lolwelo. Ivalvu yesango inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo kuphela, kwaye ayinakulungiswa okanye iqhotswe.
Isango lineendawo ezimbini zokutywina. Iindawo ezimbini zokutywina zevalvu yesango yemowudi esetyenziswa kakhulu zenza imilo ye-wedge, kwaye i-engile ye-wedge iyahluka ngokweeparamitha zevalvu.
Ivalvu yeGlobe
Umgaqo osebenzayo wevalvu yeglobe kukuxhomekeka kuxinzelelo lwesiqu sevalvu ukwenza umphezulu wokutywina idiski yevalvu uvumelane ngokusondeleyo nomphezulu wokutywina isihlalo sevalvu ukuthintela ukuhamba kwesixhobo. Xa ivalvu ivaliwe, uxinzelelo kufuneka lufakwe kwidiski ukuze kunyanzeliswe umphezulu wokutywina ukuba ungavuzi.
Iivalvu zeglobe zilungele zombini ukusetyenziswa kokuvula/ukuvala kunye nokuqhobosha. Iivalvu zeglobe ezineendlela ezimbini zikhethwa kakhulu ukulawula ukuhamba kwamanzi ngokuchanekileyo, kwaye iivalvu zeglobe ezineendlela ezintathu zihlala zisetyenziselwa ukuxuba imidiya evela kwii-inlets ezimbini kunye nokuqondisa umxube kwindawo yokuphuma.
Iivalvu Zenaliti
Ezi valve zifana kakhulu neevalvu zeglobe, kodwa zinezahluko ezimbini eziphambili. Okokuqala, zincinci, ezinokulawula ngcono ukuhamba kwemigca emincinci. Okwesibini, zisebenzisa "inaliti" ekhonkrithi endaweni yeplagi emile okwediski kunye nevalvu yenaliti ye-orifice ukulawula ukuhamba kwemigca ngokuchanekileyo.
Iivalvu zeSolenoid
Iivalvu zeSolenoid zisebenza ngokudlulisa umbane ngekhoyili, nto leyo ebangela ukuba ikhoyili ivelise intsimi yemagnethi, esebenza kwisiseko sesinyithi ukuvelisa umdla wemagnethi, kwaye isiseko sesinyithi siya kwikhoyili, nto leyo ebangela ukuba ivalvu ivuleke.
Iivalvu zeSolenoid zincinci kakhulu. Ubukhulu bazo bunqunyelwe ngamandla ekhoyili, nto leyo ebangelwa kukujijeka okusetyenziselwa ukuvelisa intsimi yemagnethi xa inikwa amandla. Ukongeza ekuthintelweni kwamandla ekhoyili, indlela yokuhamba kunye ne-orifice kwivalvu yesolenoid nazo zincinci kakhulu xa kuthelekiswa nobukhulu bombhobho.
Ivalvu yePiston ye-Angle
Ivalvu yepiston ye-angle luhlobo olukhethekileyo lwevalvu ene-actuator ye-pneumatic eyakhelwe ngaphakathi kwaye idla ngokuhlulwa njengevalvu eneendawo ezimbini. I-actuator inokuba yi-spring return okanye i-double acting, kuxhomekeke kwiimfuno zesicelo.
Inxalenye ephambili kwivalvu yiplagi yevalvu, ebekwa kumjelo wokuhamba kwegesi kwi-engile ethile kwaye ihleli kwisihlalo sevalvu esithambekileyo esibunjwe kwindlela yokuhamba kwevalvu.
Xa ivalvu ivuliwe, iplagi yevalvu iphantse irhoxe ngokupheleleyo ngaphandle komjelo wokuhamba. Olu yilo luvumela ivalvu yepiston ye-angle ukuba ibe nesantya esikhulu sokuhamba kunye nokwehla koxinzelelo oluphantsi, nto leyo eyenza ibe yivalvu esebenza ngokukhawuleza. Kwiinkqubo ezininzi zokuvula/ukucima, iivalvu zesihlalo se-angle ziyindlela engabizi kakhulu enokuthatha indawo yeevalvu zebhola zemveli.
Isishwankathelo
Kukho iintlobo ezininzi zeevalvu, kwaye uyilo lweevalvu luyahluka ngokweemeko ezahlukeneyo zokusebenza kunye neemfuno zokusetyenziswa. Ukongeza kwiivalvu ezi-8 ezisetyenziswa rhoqo ezikhankanyiweyo apha ngasentla, kukho ezinye iintlobo ezininzi zeevalvu, ezifana neevalvu zeplagi, iivalvu ezilawulayo, iivalvu ezivalayo, iivalvu zeHIPPS, njl.
Xa ukhetha ivalvu, ungajongana neUmthengisi weeValve odumileyo kwihlabathi liphelaokanyeUmzi-mveliso weValve waseTshayina.
