Amavalvu ziingcenye eziqakatheke khulu eenhlelweni zokusebenzisa. Iivalvu yesango, njengombana ibizo layo litjho, mhlobo wevalvu esetjenziselwa ukulawula ukugeleza kwe-liquid ngokusebenzisa isango nofana ipuleti. Umhlobo loivalvuisetjenziselwa ukujama ngokupheleleko nofana ukuthoma ukugeleza begodu ayisetjenziselwa ukulawula inani lokugeleza ngaphandle kobana yenzelwe ukwenza njalo.
Okuhle khuluabakhiqizi beenvalvu zebubulolandela amazinga aqinileko lokha nawukhiqiza lokhuamavalvuukuqinisekisa ikhwalithi, ukuqina, nokusebenza. Nanyana ngiliphi izinga eliphasi lingabangela umonakalo ongafunekiko nokulahlekelwa kwezomnotho. Ukusebenza kuhle nobulula bokusebenza zizinto ezimbili eziqakatheke khulu lokha nawukhetha i-valve hlangana nama-valve amanengi atholakala emakethe.
Ivalvu ye-sluiceibizwa nguivalvu yesango, qala ukuze wazi ilwazi elinabileko ngabo.
Iniis AIvalvu yesango?

A ivalvu yesangomhlobo wevalvu yokuzihlukanisa esetjenziselwa ukulawula ukugeleza kwamanzi erherhweni lamabubulo. Ii-sluicekutjho isiteshi sokwenziwa esisizwa lisango ukulawula ukugeleza kwamanzi. Amavalvu we-sluice nofanaamavalvu wesango lebubulozisetjenziselwa khulu iinhloso zebubulo. Indlela yayo elula nelula yenza bona ibe ngenye yezinto ezisetjenziswa khuluamavalvuemabubulweni ahlukahlukeneko. Ivalvu isebenza ngokuthutha nofana ukuphakamisa isithiyo endleleni yamanzi agelezako.
Isetjenziswa eceleni kwepayipi ngokugeleza okuqondileko nofana okubili. Lokha nayivulekile ngokupheleleko, ayikwazi ukujamelana noketshezi olugelezako, okungesinye seenzathu ezikulu zokuthi kubayini ithathwa njengesebenza kuhle khulu. Ijamo lesango lingaba lifana, kodwana esikhathini esinengi, ligcinwa lisebujameni be-wedge. Wedgeamavalvu wesangoirhelebha ukwenza isivalo esingcono lokha nayivaliweko ngombana ifaka umfutho ebusweni bokuvala begodu inikela ngokusebenza okungcono kokuvala.
A ivalvu yesangoisebenza ngokujikeleziswa ngesandla kwevili eliphathwa ngesandla, nofana isebenzisa i-actuator kagesi nofana ye-pneumatic.Ukujikelezisa isondo kanengi kukhuphula isango phezulu begodu phasi, okulawula ukugeleza kwamanzi nofana igesi ngaphakathi kwevalvu. Ukuvula isango kunikela ukuvimbela okuncani ekugelezeni kodwana ukugcina isango livulekile kungabangela umonakalo ngombana amanzi agelezako nofana igesi izokubeka umfutho omkhulu epuletini. Kunalokhuamavalvu wesango, amavalvu we-globe angasetjenziselwa ukulawula ukugeleza.
Ukusebenza
Nanyanaivalvu yesangonofana i-sluice valve kulula ukuyisebenzisa, ineengcenye ezinengi ezihlanganiswe ndawonye ukwenzela bona isebenze kuhle. Umhlobo loivalvuiqukethe umzimba, isango, isihlalo, ibhonethi, begodu kwezinye izehlakalo, i-actuator eyenza bona ukugeleza kugeleze ngokuzenzakalelako.Amavalvu wesangoingenziwa kusetjenziswa izinto ezihlukahlukeneko; nanyana kunjalo, insimbi engagqwali ngiyo ekhethwa khulu ngombana izinto zijamelana nokutjhuguluka kwezinga lokutjhisa nofana ukugandeleleka. Iingcenye ezihlukahlukeneko zevalvu yesango zichazwe ngezansi.
Isango
Itholakala ngeendlela ezihlukahlukeneko, isango liyingcenye ekulu yevalvu yesango. Isici esikhulu sokuklanywa kwayo yikhono layo lokuvala ukusetjenziswa okuthileko. Iivalvu yesangoingahlukaniswa njenge-valve efanako nofana ene-wedge ngokuya ngohlobo lwesango. Eyokuqala ingaphinde ihlukaniswe ibe ngamasango we-slab, amasango we-slide ahambisanako, kanye namasango afanako anwebekako.
Izihlalo
A ivalvu yesangoinezihlalo ezimbili eziqinisekisa ukuvalwa kanye nesango. Izihlalo lezi zingahlanganiswa ngaphakathi komzimba wevalvu, nofana zingaba khona ngendlela yendandatho yesihlalo. Lokhu kokugcina kufakwa ngentambo nofana kugandelelwe endaweni yayo bese kuvalwa begodu kuhlanganiswe emzimbeni wevalvu. Ebujameni lapho ivalvu ingaphasi kwamazinga womtjhiso aphezulu, amasongo wesihlalo akhethwa, ngombana avumela ukuhlukahluka okukhulu emklamweni.
Isiqu
Isango ngaphakathiivalvu yesangoyehliswa nofana iphakanyiswe lokha nayijikeleza erherhweni elineentambo. Lokhu kungenzeka ngesondo elisebenza ngezandla nofana nge-actuator. I-actionatedivalvu yesangoingalawulwa kude. Ngokuya ngomhlobo wesinyathelo, iivalvu yesangozingahlukaniswa zibe ziimvalvu zesiqu esikhuphukako nezingakhuphukiko. Eyokuqala ifakwe esangweni, kuthi eyesibili ifakwe ku-actuator begodu ifakwe ngaphakathi kwesango.
Amabhonethi
Amabhonethi ziingcenye zevalvu eziqinisekisa ukuvalwa okuphephileko kwendlela. Ingabe ifakwe ngebhawudo nofana ifakwe ngesikrufu emzimbeni wevalvu ukwenzela bona ikhutjhwe ukuze ibuyiselwe nofana ilungiswe. Ngokuya ngokusetjenziswa, imihlobo ehlukileko yamabhonethi wevalvu ifaka hlangana amabhonithi we-bolt, amabhonethi we-screw-in, amabhonethi we-union, kanye namabhonethi we-pressure seal.
Iimbawo
Amavalvu wesangonofana amavalvu we-sluice aneensetjenziswa ezinengi emabubulweni ahlukahlukeneko begodu aneensetjenziswa ezihlukahlukeneko ekulawuleni amanzi, igesi, ngitjho nokugeleza komoya. Ebujameni obumbi bebhoduluko njengeendawo ezinezinga lokutjhisa eliphezulu nofana ezinomfutho omkhulu emabubulweni we-petrochemical, amavalvu wesango ngiwo asetjenziswa khulu. Ebujameni obunjalo, izinto kanye nomhlobo wevalvu zidlala indima eqakathekileko ekusebenzeni nasekusebenzeni kuhle kwevalvu.
Amavalvu wesango nawo asetjenziswa eenhlelweni zokuphepha emlilweni, laphoivalvu yesango elinefletjhiisetjenziswa khulu.Amavalvu wesango lesiqu elingakhuphukikozisetjenziswa emikhunjini nofana ngaphasi kwehlabathi eendaweni lapho isikhala esijame ngqo silinganiselwe khona.
ImihloboAmavalvu wesango
Umthombo:I-TWS Valve
Okufanako begodu okubunjwe njenge-WedgeAmavalvu wesango
Njengombana ibizo lisikisela, amavalvu wesango lokutjhelela eliphambeneko linesango eliphaphathekileko, eliqalene elifanako elifakwe hlangana nezihlalo ezimbili eziphambeneko. Ngakelinye ihlangothi, i-wedgeamavalvu wesangoibe nesango elifana ne-wedge. Lokhu kuneembambo emahlangothini womabili begodu kuqondiswa endaweni yizikhala emzimbeni wesango. Iinqophiso ze-wedge zisiza ukudlulisa imithwalo ye-axial ebekwe yi-medium emzimbeni wevalvu, yenza bona kube nokunyakaza okuncani, begodu ivimbele ukujikeleza kwe-wedge lokha nayihamba hlangana neendawo ezivulekileko nezivaliweko.
Amavalvu weSango lesiqu esikhuphukako nesiqu esingakhuphukiko
Umehluko omkhulu hlangana nemihlobo emibili leamavalvu wesangokukuthi zingajame (zikhuphuka) nofana zifakwe ngentambo (zingakhuphuki). Ngaphakathiamavalvu wesango lesiqu esikhuphukako, isiqu esijikelezako siphakama ngesikhathi ivalvu ivuleka. Kodwana, umhlobo lo wevalvu awukhethwa lapho isikhala sincani nofana ukufakwa kungaphasi komhlaba.
Amavalvu wesango ahlala phasi begodu aqinileko
Kokubili lokhu ku-wedgeamavalvu wesango. Ngaphakathiamavalvu ahleziko wensimbi, i-wedge itjhelela iye emgodiniivalvu yesangoumzimba begodu ungabamba izinto eziqinileko ezingaba nazo uketshezi. Ngikho,amavalvu ahlezi aqinilekozikhethwa lapho kutlhogeka khona ukuvala okuqinileko, njengasemahlelweni wokusabalalisa amanzi.
In amavalvu ahlezi aqinileko, i-wedge ivalwe ngaphakathi kwe-elastomer eqinisekisa ukuvalwa okuqinileko. Ukuhlala kwenzeka hlangana nomzimba wevalvu ne-wedge begodu ngalokho akutlhogeki bona kube ne-groove njenge-valve yesango ehlezi yensimbi. Njengombana amavalvu la ahlanganiswe nge-elastomer nofana into eqinileko, anikela ngezinga eliphezulu lokuvikela ukugqwala.
Amagama wokugcina
Amavalvu we-sluice kanyeamavalvu wesangongamagama ahlukileko womhlobo ofanako wevalvu. Lokhu mhlobo ovame khulu weamavalvu webubuloesetjenziswako. Njengombana amavalvu wesango enziwa ngokusebenzisa izinto ezihlukahlukeneko begodu anemihlobo eminengi, umhlobo wevalvu kufanele ukhethwe ngokutjheja malungana nokusetjenziswa okuthileko.
Ikhwalithi ehle begodu isebenza kuhleamavalvunjengalawo kaI-TWS Valveyimali ehle khulu ngombana itlhoga ukutlhogonyelwa okuncani esikhathini eside, okungasindisa imali enengi. UkuthintanaIvalvu I-TWS Valvenamhlanjesi malungana namavalvu aphuma phambili.
