I-Palve yesangoyiveli eqhelekileyo enesidima ngokubanzi ngoluhlu olubanzi lokusetyenziswa. Isetyenziswa ikakhulu kumanzi ogcino, amanye amashishini. Uluhlu lwayo lwentsebenzo luye lwamkelwa yimarike. Ukongeza kufundisiso lwe-valve yesango, yenze isifundo esinzulu nesinyanzelekileyo ngokusetyenziswa kunye nokucocwa kwengxaki yeIivalves zesango.
Oku kulandelayo yingxoxo ngokubanzi malunga nesakhiwo, ukusetyenziswa, ukucocwa kwengxaki, uhlolo lwemigangatho kunye neminye imiba yeI-valves yesango.
1. Ulwakhiwo
Ubume beI-Palve yesango: II-Palve yesangoyivali esebenzisa iplate yesango kunye nesitulo sevali ukulawula ukuvulwa nokuvalwa.I-Palve yesangoEyona nto iqulathe ikakhulu i-valve, isitulo se-valve, iplate yesango, i-valve stem, i-bonnet, ibhokisi yokufaka, i-pherte, i-stemne, njalo. Kuxhomekeka kutshintsho lwesihlobo phakathi kwesango kunye nesihlalo sevali, ubungakanani besitayile sinokutshintshwa kwaye ijelo linganqunyulwa. Ukuze wenzeI-Palve yesangoVala ngokuqinileyo, umphezulu wokutshata weplate yesango kunye nesitulo sevali.
Ngokwemilo eyahlukeneyo yesakhiwoI-valves yesango, I-valve yesango inokwahlulwa ngohlobo lomtshato kunye nohlobo olufanayo.
Isango lomtshatoI-Palve yesangoI-Wedge-Speedge-Histal I-TOPLE i-angle ye-oblique kunye nomgca wesitishi, kunye nomtshato phakathi kwesango nesihlalo sevali sisetyenziselwa ukutywina (ukuvala ivali). Iplate ye-Wedge inokuba yigusha enye okanye i-ram ezimbini.
Umphezulu wokutywina we-valve yesango elifanayo kunye ne-perpendicular ukuya kumgca wesitishi, kwaye zimbini iintlobo: ngendlela yokwandiswa kwendlela yokwandiswa. Kukho iinkunzi zeegusha eziphindwe kabini ngenkqubo yokwanda. Xa iinkunzi zeegusha zihla, imitshato yeenkunzi zeegusha ezimbini ezifanayo ziya kusasazeka iinkunzi zeegusha ezimbini kwisitulo sevali kwisitulo esithobekileyo sokuthintela ijelo lokuhamba. Xa iinkunzi zeegusha ziphakama kwaye zivulekile, imitshato kunye namasango aya kuzaliseka umphezulu weplate, iplate inyuka, iplate yesango ixhaswa ngumphathi weplate yesango. Isango eliphindwe kabini ngaphandle kwendlela yokwandiswa, xa isango lisibhabha kwisitulo esinezihlalo esifanayo, ingcinezelo yolwelo isetyenziselwa ukucofa i-valve kwi-valve yokutywina.
Ngokwentshukumo ye-valve tite xa ivuliwe isango kwaye ivaliwe, i-valve yesango yahlulwe yangumbini iintlobo zesango kunye ne-valve yesango elifihlakeleyo. I-valve stem kunye neplate yesango ye-Stemp ye-Stemp Palve inyuka kwaye iwele ngaxeshanye xa ivuliwe okanye ivaliwe; Xa i-valve yesango elifihliweyo ye-Stemp ivuliwe okanye ivaliwe, i-valve ijikeleza kuphela, kwaye ukuphakamisa kwe-valve akunakubonwa, kwaye i-vate ye-vate iphakama okanye iwa i-vate ye-vatve. Inzuzo ye-valve yesango le-STEM le yeyokuba ukuphakama kwejelo kunokugwetywa ngokunyuka kwesiqu se-valve, kodwa ukuphakama okuhlala kunqunyulwa. Xa ujongene nesandla okanye isiphatho, jika isiphambuka okanye ukuphatha iwotshi yokuvala ivalve.

I-02. Ukugcinwa kweI-Palve yesango
(1) Ukulungiswa kwe-valve yangaphandle yokuvuza
Xa ucinezela ukupakisha, iibhloksi ze-gland kufuneka zilungelelaniswe ukuthintela i-gland ukusuka ekutsaleni kwaye ishiye umsantsa sokuqubuka. Ngelixa ucinezela ukupakisha, i-valve stem kufuneka ijikelezwe ukuba ikhuphe iyunifomu ye-valve stem, kwaye inqande ukujikeleza kwe-valve, yandise ukunxiba, kwaye inciphise ubomi benkonzo. Umphezulu we-valve stem ukrwitshwe, nto leyo eyenza lula ukuvuza. Ifanele iqhubekiswe ukuphelisa ukukrwada komphezulu we-valve ngaphambi kokusetyenziswa.
Ukuvuza koqhagamshelo lweflethi, ukuba i-garket yonakala, kufuneka itshintshwe; Ukuba umxholo we-gasket ukhetha ngokungafanelekanga, umbandela onokuhlangabezana neemfuno zokusetyenziswa kufuneka ukhethe; Ukuba umgangatho wokuqhubela komgangatho wokutywina iFlange uhlwempuzekile, kufuneka isuswe kwaye ilungiswe. Umhlaba wokutywina uphoselo udashwe de kuqinisekiswe.
Ukongeza, ukuqiniswa okufanelekileyo kwee-bolts zeflethi, ubumbeko oluchanekileyo lwemibhobho, kwaye kuthintele umthwalo ogqithisileyo kwiFlanges
(2) Ukulungiswa kokuvuza kwe-valve
Ukulungiswa komvuzo wangaphakathi kukuphelisa umonakalo womphezulu kunye neengcambu ezikhululekileyo zendandatho (xa iringi yokutywina ihleliwe kwiplate ye-valve okanye isitulo). Ukuba indawo yokutywina iqhubekeka ngqo kwi-valve kunye neplate ye valve, akukho ngxaki yengcambu kunye nokuvuza.
Xa umhlaba wokutywina wonakaliswe kakhulu kwaye umhlaba wokutywina usekwe ngumsesane wokutywina, iringi yakudala kufuneka isuswe kwaye iringi entsha yokutywina kufuneka ibonelelwe; Ukuba indawo yokutywina iqhubekeka ngqo kwi-vali yevali, umphezulu owonakalisiweyo wokutywina kufuneka ususwe kuqala. Susa, kwaye emva koko jikisa iringi entsha yokutywina okanye indawo esetyenzisiweyo kumgangatho omtsha wokutywina. Xa sukuqhekeka, amagqabantshintshi, i-crshes, dents kunye nezinye iziphene kumhlaba wokutywina ungaphantsi kwe-0.05mm, banokupheliswa ngokugaya.
Ukuvuza kwenzeka kwingcambu yeringi yokutywina. Xa iringi yokutywina ilungisiwe ngokucinezela, beka i-titrafluoroothylene tape okanye ipeyinti emhlophe kwiivalveisihlalo okanye ezantsi komsesa weringi yeringi yokutywina, kwaye emva koko cinezela iringi yokutywina ukuze ugcwalise ingcambu yeringi yokutywina; Xa i-ring yokutywina i-theiring i-theip itreyini, i-Ptfed Tape okanye ipeyinti emhlophe ifanele ibekwe phakathi kwemisonto ukuthintela i-fluid ekwiphepha lemisonto.
(3) Ukulungiswa kwe-vlosion
Phantsi kweemeko eziqhelekileyo, i-valve ibhulukhwe kwaye i-bonnet ingenayo, ngelixa i-valve stem ihlala ifakwa. Xa kulungiswa, iimveliso ze-corrosion kufuneka zisuswe kuqala. Kwi-valve stem enemingxunya yokugqobhoza, kufuneka iqhubekeke kwi-lathe yokuphelisa uxinzelelo, kwaye usebenzise i-filler equkethe amanzi okukhupha kancinci, okanye ucoce amanzi amdaka anobungozi kwi-filve enobungozi kwi-filve enobungozi. I-ions evelayo.
(4) Ukulungiswa kokukrazula kumphezulu wokutywina
Ngexesha lokusetyenziswa kwe-valve, zama ukukhusela umphezulu wokutywina ukuba ungakrwitshiwe, kwaye itotque ayifanelanga kakhulu xa ivala ivalve. Ukuba indawo yokutywina ikhutshiwe, inokususwa kukugaya.
