Itucezu oluthathutihreadedvi-alve yin a uhlobo lokufakwa kwamapayipi amakhemikhali.Kukhona umumo ka-T kanye nesimo sika-Y.Kukhona nezinciphisi.Ukuze kuhlangane amapayipi amathathu.
Izixhumi zamapayipi ezenziwe ngensimbi eyindilinga noma i-ingot yensimbi yokufaka insimbi, ifomu layo lokuxhuma liyi-socket welding, ipayipi lensimbi lifakwa embotsheni yesokhethi yokushisela, ngakho-ke kubizwa ngokuthi "ukufakwa kwepayipi lesokhethi", indinganiso yokukhiqiza eyinhloko ANSI/ASME B16. .11, MSS SP-83, GB/T 14383-2008.
I-Socket Fittings
Izinhlobonhlobo zokufakwa kwamapayipi e-socket zihlanganisa 45°indololwane, 90°indololwane, i-socket tee, isiphambano, 45°i-oblique tee, i-double socket pipe clamp, i-clamp eyodwa yepayipi yesokhethi, i-pipe cap, inyunyana, isihlalo samapayipi egatsha nokunye.Phakathi kwazo, ama-tee neziphambano zinamadayamitha alinganayo nobubanzi obuhlukene;izinsimbi zamapayipi ezinesokhethi ezimbili nazo zinamadayamitha alinganayo nobubanzi obuhlukene, futhi izinsimbi zamapayipi ezinesokhethi ezimbili ezinobubanzi obuhlukene zingabuye zihlukaniswe zibe yi-concentric ne-eccentric.
Insimbi engagqwali3pc intambo i-valve yebhola
Insimbi engagqwali3pc intambo ibhola valve Insimbi engagqwali3pc intambo i-valve yebhola kanye ne-valve yesango ye-flange ingeyohlobo olufanayo lwe-valve, umehluko wukuthi ingxenye yayo yokuvala iyindilinga, futhi imbulunga izungeza umugqa omaphakathi womzimba we-valve ukuze kuzuzwe ukuvula nokuvala.Ama-valve ebhola asetshenziswa kakhulu kumapayipi ukusika, ukusabalalisa kanye nokushintsha indlela yokuhamba kwemidiya.I-valve yebhola eneziqephu ezimbili kanye ne-valve yebhola eneziqephu ezintathu kuwuhlobo olusha lwevalvu esetshenziswa kabanzi eminyakeni yamuva.
Okokuqala, tyena insimbi engagqwali3pc intambo I-valve yebhola inezinzuzo ezilandelayo:
1. Ukumelana noketshezi kuncane, futhi i-coefficient yayo yokumelana ilingana nengxenye yepayipi yobude obufanayo.
2. Isakhiwo esilula, usayizi omncane kanye nesisindo esincane.
3. Ihlangene futhi inokwethenjelwa.Njengamanje, indawo yokuvala uphawu ye-valve yebhola isetshenziswa kabanzi kumapulasitiki, anokusebenza okuhle kokuvala futhi isetshenziswe kabanzi ezinhlelweni ze-vacuum.
4. Kulula ukuyisebenzisa, ukuvula nokuvala ngokushesha, udinga kuphela ukuzungezisa okungu-90°kusukela ekuvuleni ngokugcwele kuya kokuvaleka ngokugcwele, okulungele isilawuli kude.
5. Ukugcinwa kulula, ukwakheka kwe-valve yebhola kulula, indandatho yokuvala ngokuvamile iyasuswa, futhi kulula kakhulu ukuyihlakaza nokufaka esikhundleni.
6. Uma ivuliwe ngokugcwele noma ivalwe ngokugcwele, indawo yokuvala yebhola kanye nesihlalo se-valve ihlukaniswa phakathi nendawo, futhi lapho okuphakathi kudlula, ngeke kubangele ukuguguleka kwendawo yokuvala i-valve.
7. Inezinhlobonhlobo zezinhlelo zokusebenza, ezinobubanzi obuncane njengamamilimitha ambalwa futhi bukhulu njengamamitha amaningana, futhi ingasetshenziswa kusukela ku-vacuum ephezulu kuya ekucindezelweni okuphezulu.
Ama-valve ebhola esiteji aphezulu angahlukaniswa ngohlobo oluqondile,3pc intambo thayipha kanye nohlobo lwe-engeli yesokudla ngokuya ngokuma kwesiteshi.Ama-valve amabili okugcina ebhola asetshenziselwa ukusabalalisa okuphakathi nokushintsha isiqondiso sokugeleza kwe-medium.Ukufakwa nokugcinwa kwe-valve yebhola eneziqephu ezintathu kufanele kunake lezi zinto ezilandelayo:
1. Shiya indawo ukuze isibambo sevalvu sizungeze.
2. Ayikwazi ukusetshenziswa njenge-throttling.
Amavalvu amabhola ama-3 anemishini yokudlulisela kufanele afakwe aqonde.
Okwesibili, isimiso sokusebenza sensimbi engagqwali3pc intambo I-valve yebhola ukwenza i-valve ivuleke noma ivinjwe ngokuzungezisa i-valve.I-valve yebhola kulula ukuyishintsha, isayizi encane, ingenziwa ibe ububanzi obukhulu, enokwethenjelwa ekubekweni uphawu, ilula ngesakhiwo, ilungele ukugcinwa, futhi indawo yokuvala kanye ne-spherical surface ihlale isesimweni esivaliwe, okungelula. ezocekelwa phansi yi-medium, futhi isisetshenziswe kakhulu ezimbonini ezahlukahlukene.
Third, insimbi engagqwali3pc intambo I-valve yebhola isetshenziswa kakhulu epayipini ukusika, ukusabalalisa kanye nokushintsha indlela yokuhamba kwe-medium.I-valve yebhola iwuhlobo olusha lwe-valve esetshenziswa kabanzi eminyakeni yamuva nje, inezinzuzo ezilandelayo:
1. Ukumelana noketshezi kuncane, futhi i-coefficient yayo yokumelana ilingana nengxenye yepayipi yobude obufanayo.
2. Isakhiwo esilula, usayizi omncane kanye nesisindo esincane.
3. Ihlangene futhi inokwethenjelwa.Njengamanje, indawo yokuvala uphawu ye-valve yebhola isetshenziswa kabanzi kumapulasitiki, anokusebenza okuhle kokuvala futhi isetshenziswe kabanzi ezinhlelweni ze-vacuum.
4. Kulula ukuyisebenzisa, ukuvula nokuvala ngokushesha, udinga kuphela ukuzungezisa okungu-90°kusukela ekuvuleni ngokugcwele kuya kokuvaleka ngokugcwele, okulungele isilawuli kude.
5. Ukugcinwa kulula, ukwakheka kwe-valve yebhola kulula, indandatho yokuvala ngokuvamile iyasuswa, futhi kulula kakhulu ukuyihlakaza nokufaka esikhundleni.
6. Uma ivuliwe ngokugcwele noma ivalwe ngokugcwele, indawo yokuvala yebhola kanye nesihlalo se-valve ihlukaniswa phakathi nendawo, futhi lapho okuphakathi kudlula, ngeke kubangele ukuguguleka kwendawo yokuvala i-valve.
7. Inezinhlobonhlobo zezinhlelo zokusebenza, ezinobubanzi obuncane njengamamilimitha ambalwa futhi bukhulu njengamamitha amaningana, futhi ingasetshenziswa kusukela ku-vacuum ephezulu kuya ekucindezelweni okuphezulu.Lapho ibhola lizungeza ama-degree angama-90, yonke indawo yokungena nokuphuma kufanele ibonakale iyindilinga, ukuze kunqamuke ukugeleza.
Insimbi engagqwali3pc intambo I-valve yebhola iwuhlobo olusha lwe-valve yebhola.Inezinzuzo ezithile ezihlukile kwesakhiwo sayo, njengokuthi akukho ukungqubuzana ekushintsheni, akukho lula ukugqoka uphawu, kanye ne-torque encane yokuvula nokuvala.Lokhu kunciphisa usayizi we-actuator ehlobene.Ifakwe i-multi-turn actuator kagesi, ingabona ukulungiswa nokunqanyulwa okuqinile kokuphakathi.Isetshenziswa kabanzi ku Petroleum, Chemical, ukuphakelwa kwamanzi emadolobheni kanye nokukhipha amanzi kanye nezinye izimo zokusebenza ezidinga ukunqanyulwa okuqinile.
Okwesine, umgomo wayo wokusebenza umi kanje:
A. Qala inqubo
1 Endaweni evaliwe, ibhola licindezelwa esihlalweni sevalvu ngu ukucindezela komshini[/wiki] kwesiqu se-valve.
2 Lapho isondo lesandla liphendulwa ngokuphambene newashi, isiqu se-valve sihamba siye kolunye uhlangothi, futhi indiza eyi-angular engezansi kwevalvu yenza ibhola liphume esihlalweni.
3 Isiqu se-valve siyaqhubeka nokuphakama, futhi sisebenzelana nephinikhodi emseleni ovunguzayo wesiqu se-valve, ukuze ibhola liqale ukuzungezisa ngaphandle kokungqubuzana.
4 ize ifike endaweni evuleke ngokugcwele, isiqu se-valve siphakanyiselwa endaweni elinganiselwe, futhi ibhola lizungeza endaweni evuleke ngokugcwele.
B. Inqubo yokuvala
1 Uma ivaliwe, phendula isondo lesandla ngokwewashi, isiqu se-valve sizoqala ukwehla futhi ibhola lizoshiya isihlalo sevalvu bese liqala ukujikeleza.
2 Qhubeka uzungezisa isondo lesandla, futhi isiqu se-valve senziwa yiphini lokuqondisa elishunyekwe ku-spiral groove kuyo, ukuze isiqu se-valve nebhola zijikeleze 90.°ngesikhathi esifanayo.
3 Uma sekuzovalwa, ibhola selijike ngama-90° ngaphandle kokuxhumana nesihlalo se-valve.
4 Phakathi nokuphenduka okumbalwa kokugcina kwesondo lesandla, indiza eyi-angular ezansi kwesiqu se-valve ijika ngokumshini ngokumelene nebhola ukuze ilicindezele ngokuqinile esihlalweni sevalvu ukuze ifinyelele uphawu oluphelele.
Okwesihlanu, izici zesakhiwo sensimbi engagqwali3pc intambo I-valve yebhola:
1. Vula futhi uvale ngaphandle kokungqubuzana.Lo msebenzi uxazulula ngokuphelele okuvamilevi-alve. Inkinga yokuthinta uphawu ngenxa yokungqubuzana phakathi kwezindawo zokuvala.
2. Isakhiwo sokulayisha phezulu.I-valve efakwe epayipini ingahlolwa futhi ilungiswe ngokuqondile ku-inthanethi, okunganciphisa ngempumelelo ukuvala ucingo futhi kunciphise izindleko.Lolu hlobo lwe-valve ngokuvamile kufanele lufakwe ngokuvundlile epayipini.
3. Umklamo wesihlalo esisodwa.Iqeda inkinga yokuthi i-medium emgodini we-valve ithinta ukuphepha kokusetshenziswa ngenxa yokwanda kwengcindezi engavamile.
4. Idizayini yetorque ephansi.Isiqu se-valve esinomklamo okhethekile wesakhiwo singavulwa kalula futhi sivalwe ngesibambo esincane kuphela.
5. Isakhiwo sokuvalwa kwe-Wedge.I-valve ivalwa ngokucindezela i-wedge yebhola esihlalweni se-valve ngamandla omshini anikezwe isiqu se-valve, ukuze ukusebenza kokuvala kwe-valve kungathintwa ukushintsha umehluko womfutho wepayipi, futhi ukusebenza kokuvala kuqinisekiswe ngokuthembekile ngaphansi. izimo zokusebenza ezehlukene.
6. Isakhiwo sokuzihlanza sendawo yokubeka uphawu.Lapho ibhola litshekela kude nesihlalo sevalvu, uketshezi olusepayipini ludlula ngokulinganayo ku-360.°eduze kwendawo yokuvala ibhola, okungagcini nje ngokuqeda ukuguguleka kwendawo kwesihlalo se-valve ngoketshezi olunesivinini esikhulu, kodwa futhi kugeze ukunqwabelana endaweni evalekayo, kufezwe injongo yokuzihlanza .
