Abantu abaninzi bafuna ukwazi indlela yokusebenza kwevalve yesango etywiniweyo ukuze bayisebenzise ngcono le valve.Oku kulandelayo yindlela yokusebenza kunye nendlela yokuphelisa isiphene sevalve yesango etywiniweyo:
Okokuqala, indlela yokuvula kunye nokuvala i-valve, abaqhubi abaninzi bahlala besenza iimpazamo apha, kufuneka bakhumbule ukuba i-valve yokuvala isalathiso yi-clockwise.
Okwesibini, ukuba ivalve yesango yokutywina ethambileyo isetyenziswa kwinkqubo yombhobho, isixhobo somoya ngaphakathi kwevalve sifuna ukusebenza ngesandla, kwaye abantu kufuneka basebenzise iindlela zezandla ukuyivula nokuvala.Ukuba i-valve yobubanzi obukhulu, inani lamaxesha okuvulwa nokuvala kufuneka ligcinwe phakathi kwamaxesha angama-200 ukuya kuma-600.
Okwesithathu, umgama wokuvula kunye nokuvala amandla wevalve yesango etywiniweyo kufuneka ugcinwe ngaphakathi koluhlu oluthile, ngokukodwa ukugcina abasebenzi kunye nokuququzelela umntu omnye ukuba asebenze.Ukuba umgama wamandla udlula olu luhlu, ubuncinane abantu ababini ukuya kwabathathu bayafuneka ukuqalisa ngempumelelo ivalve..
Okwesine, ubungakanani bevalve kufuneka bube semgangathweni.Xa ubeka ivalve, kufuneka ubeke ingqalelo kwivalve yevalve yesango ejonge phantsi.
Ivalve yesango yokutywina ethambileyoindlela yokuphelisa ingxaki:
1. Ukuvuza ekupakishweni kwevalve yesango etywiniweyo
(1) Idlala lokupakisha likhululekile kakhulu, kwaye indongomane yokucinezela idlala lokupakisha inokuqiniswa ngokulinganayo.
(2) Inani lemijikelezo yokupakisha ayanele, kwaye ukupakisha kufuneka kwandiswe.
(3) Ukupakishwa kuyasilela ngenxa yokusetyenziswa kwexesha elide okanye ukugcinwa okungafanelekanga.Kufuneka itshintshwe ngokupakisha entsha.Xa ukutshintshwa, kufuneka kuqatshelwe ukuba amajoyina phakathi kwendandatho nganye kufuneka agqitywe kwaye agxininiswe.
2. Kukho umsantsa phakathi kwepleyiti yesango yevalve yesango etywiniweyo kunye nomphezulu wokutywina wesihlalo sevalve.
(1) Kukho ukungcola phakathi kweendawo zokutywina, ezinokuthi zipheliswe ngokuhlamba.
(2) Ukuba indawo yokutywina yonakalisiwe, kufuneka iphinde ihlanjwe, kwaye ukuba kuyimfuneko, inokuphinda iphinde iphinde iqhutywe.Umphezulu wokutywinwa komhlaba kufuneka ube mcaba, kwaye uburhabaxa bawo abufanele bube ngaphantsi kwe-0.4.
3. Inathi evuzayo kumdibaniso phakathi komzimba wevalve kunye nebhonethi yevalve yesango etywiniweyo ayiqiniswanga ngokuqinileyo okanye ayiqiniswanga ngokulinganayo, kwaye inokulungiswa ngokutsha.
(1) Umonakalo (iigrooves ezithe tye okanye iimpawu zegroove, njl.njl.) kumphezulu wokutywina weflange kufuneka ulungiswe.
(2) I-gasket yonakele kwaye kufuneka itshintshwe ngegasket entsha.
4. Ugqithiso lwesikhondo sevalve yesango lokutywina alubhetyebhetye
(1) Ukuba ukupakisha kuqinile kakhulu, khulula i-nut kwi-packing gland ngokufanelekileyo.
(2) Indawo yedlala yokupakisha ayichanekanga, ukwenzela ukuba isiqu sevalve sibambeke, kwaye indongomane kwidlala lokupakisha kufuneka ijijwe ngokulinganayo ukubuyisela idlala kwindawo yalo eqhelekileyo.
(3) Imisonto kwisiqu kunye ne-stem nut yonakele kwaye kufuneka isuswe emva kokuqhawulwa.
Iivalvu zesango lokutywina ezithambileyo zisetyenziswa kakhulu.Ivalve yesango lokutywina elithambileyo, ivalve yeshishini, indawo yokuvula kunye nokuvala ivalve yesango lokutywina elithambileyo lisango, indlela yokuhamba yesango ixhomekeke kwicala lolwelo, ivalve yesango inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo, kwaye ayinakulungiswa okanye icinezelwe.Ipleyiti yesango ineendawo ezimbini zokutywina.Imiphezulu emibini yokutywina yevalve yesango le wedge esetyenziswa ngokuxhaphakileyo zenza imilo ye wedge.I-engile ye-wedge shape angle iyahluka kunye neeparamitha zevalve, idla ngokuba yi-50, kunye ne-2 ° 52 xa ubushushu obuphakathi bungekho phezulu.
