Uhlalutyo olunzulu lwemigangatho yaseTshayina eyenziwe ngeevalvu zesango lentsimbi
Intshayelelo:
Phakathi kweenkqubo ezininzi zemibhobho yemizi-mveliso, kukho isixhobo esidlala indima ebalulekileyo- oko kukuthi, umgangatho wesizwe owenziweyo wevalve yesango yentsimbi eyenziweyo. Njengohlobo lwevalve esetyenziswa kakhulu kwimimandla efana nepetroleum, iikhemikhali, kunye nesinyithi, iqinisekisa ukhuseleko kunye nokusebenza kakuhle kokuthuthwa kwamanzi kunye nokusebenza kwayo okugqwesileyo kunye nomgangatho othembekileyo. Namhlanje, siza kutyhila isigqubuthelo esingaqondakaliyo somgangatho wesizwe owenziwe ngentsimbi ivelufa yesango lentsimbi kwaye siphonononge inyani.
1, Yintoni umgangatho wesizwe ivelufa yesango yentsimbi eyenziwe ngomkhando?
Umgangatho wesizwe owenziweyo wentsimbi yentsimbi yomxokozelo ivelufa yesango ibhekisa kwivalve yesango edityanisiweyo yeflange eyilelwe kwaye yenziwe ngokungqinelana nomgangatho wesizwe waseTshayina (umgangatho we-GB), kusetyenziswa intsimbi yomgunyathi njengento ekrwada. Olu hlobo lwevalve luhlala lusetyenziselwa ukudibanisa okanye ukunqumla ukuhamba kwe-medium kwimibhobho, ngokukodwa ifanelekileyo kuxinzelelo oluphakathi kunye noxinzelelo oluphezulu.
2. Iimpawu zesakhiwo
1. Umzimba wevalvu: Umzimba wevalvu womgangatho wesizwe owenziweyo wentsimbi ivelufa yesango lentsimbi yenziwe ngenkqubo yokubumba, eyenza umzimba wevalvu ube namandla omatshini aphezulu kunye nokumelana noxinzelelo.
2. Isihlalo seValve: Ngokuqhelekileyo, i-alloy eqinileyo enokutshintshwa okanye izinto zensimbi ezingenasici zisetyenziselwa ukuphucula ukutywinwa kunye nokuqina.
3. I-valve stem: I-valve stem yenzelwe imicu ye-trapezoidal, iqinisekisa ulawulo oluchanekileyo ngexesha lokuvula nokuvalwa.
4. Imowudi yokuqhuba: Ukusebenza ngesandla yeyona nto ixhaphakileyo, kodwa inokwenziwa ngokwezifiso njenge-pneumatic okanye umbane ngokweemfuno zangempela.
5. Ifomu yokutywina: Ngokuxhomekeke kwiimeko ezahlukeneyo zokusebenza, ukutywinwa okuthambileyo okanye ukutywinwa kanzima kunokukhethwa.
3. Umgaqo wokusebenza
Umgaqo-siseko wesizwe womgangatho wesizwe owenziwe ngentsimbi yentsimbi yevalve yesango iyinto ecacileyo. Xa ivalve kufuneka ivalwe, jikelisa ivili lesandla okanye isixhobo sokuqhuba ukuthoba isikhondo sevalve, uze utyhale isango ukuba liye ezantsi de isango livale ngokupheleleyo umjelo wolwelo, ukuphumeza ukuvala; Ngokuchasene noko, xa kuyimfuneko ukuvula i-valve, phakamisa isango ukuze uvumele ulwelo ukuba luhambe.
4. Iinzuzo zokusebenza
1. Ukuxhathisa okuqinileyo kwe-corrosion: Ngenxa yokusetyenziswa kwezinto eziphezulu zensimbi ezibunjiweyo, i-valve inokumelana kakuhle neekhemikhali ze-corrosion.
2. Ukumelana nokunxiba: Izinto zentsimbi ezibunjiweyo kunye noyilo olufanelekileyo lomjelo wokuhamba kunciphisa ukukhukuliseka kwamanzi kunye nokunxiba kwivalve.
3. Ukugcinwa okulula: Ngenxa yoyilo lwezakhiwo ezinokutshintshwa kwizinto eziphambili ezifana nezihlalo zevalve, kulungele ukugcinwa kwemihla ngemihla kunye nokutshintshwa.
4. Ubomi benkonzo ende: Isakhiwo esomeleleyo kunye nezixhobo eziphezulu ziqinisekisa ukuthembeka kunye nokuqina kwevalve phantsi kweemeko zokusebenza ezinzima.
5. Umda wosetyenziso
Izivalo zesango zentsimbi zentsimbi ezibunjiweyo zisetyenziswa ngokubanzi kwipetroleum, igesi yendalo, imichiza, iinkqubo zokufudumeza, kunye namanye amasimi oshishino ngenxa yokusebenza kwawo okugqwesileyo. Ngokukodwa kwiimeko apho iimfuno zevalve ziphezulu, ezifana nokulawula ubushushu obuphezulu, uxinzelelo oluphezulu, kunye neendaba ezidliwayo, iivalve zesango zentsimbi ezibunjiweyo zinokudlala indima ebalulekileyo.
Isiphelo:
Umgangatho wesizwe owenziweyo wentsimbi yentsimbi yevalve yesango iye yaba yinto eyimfuneko kushishino lwanamhlanje ngenxa yokusebenza kwayo okugqwesileyo kunye nokusetyenziswa okubanzi. Ukuqonda ukwakhiwa kwayo, imigaqo, kunye neenzuzo kunokusinceda ukuba sikhethe ngcono kwaye sisebenzise iivalvu ezinjalo, ngaloo ndlela siqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kweenkqubo zemibhobho. Ngokuqhubela phambili okuqhubekayo kwetheknoloji, ukusebenza kweevalve zesango zentsimbi ezibunjiweyo ziya kuba ziphezulu kwixesha elizayo, kwaye iindawo zabo zokusetyenziswa ziya kuba zibanzi.
