Bite ho mugihe umubiri wa valve ubora? Ibisobanuro birambuye byuburyo bwo guhuza ibikoresho byinshi byahinduwe na valve igikoresho (I)

Hamwe niterambere ryubuhanga, umusaruro winganda zubushyuhe bwo hejuru, umuvuduko mwinshi, ubukonje bwinshi, icyuho kinini, ruswa ikomeye, radioaktike, yaka umuriro kandi iturika nibindi bipimo bihanitse byimiterere y’akajagari biriyongera, hanyuma bigashyirwa hejuru kandi bisabwa cyane kugirango umutekano wo gukoresha valve, imikorere yikigo nubuzima bwa serivisi.
Kubera ko ruswa ibaho mu mikoranire idahwitse hagati yicyuma n’ibidukikije, uburyo bwo gutandukanya ibyuma n’ibidukikije cyangwa gukoresha ibikoresho bya sintetike bitari ibyuma ni byo byibandwaho mu gukumira ruswa. Kwangirika kwa Valve, mubisanzwe byumvikana nkibikoresho bya valve mubikorwa bya chimique cyangwa electrochemic ibidukikije byangiza.
Valve umubiri wangirika muburyo bubiri, aribwo kwangirika kwimiti no kubora amashanyarazi. Igipimo cyacyo cya ruswa giterwa nubushyuhe, umuvuduko, imiterere yimiti yo hagati hamwe no kurwanya ruswa yibintu byumubiri. Umuvuduko wa ruswa ushobora kugabanywamo ibice bitandatu:
1, kurwanya ruswa yuzuye: umuvuduko wa ruswa uri munsi ya 0.001 mm / mwaka;
2, kurwanya ruswa cyane: umuvuduko wa ruswa 0.001 kugeza 0.01 mm / umwaka;
3, kurwanya ruswa: umuvuduko wa ruswa 0.01 kugeza 0.1 mm / mwaka;
4, kurwanya ruswa: umuvuduko wa ruswa 0.1 kugeza 1.0 mm / umwaka;
5, kurwanya ruswa nabi: umuvuduko wa ruswa 1.0 kugeza 10 mm / mwaka;
6, kurwanya ruswa: umuvuduko wo kwangirika urenze mm 10 / umwaka.
Nubwo amakuru yo kwirinda kwangirika kwumubiri ari menshi cyane, ariko ntibyoroshye guhitamo neza, kuko ikibazo cyo kwangirika kiragoye cyane, ubwo ni ubuhe buryo bwo kurinda umubiri wangirika?
Mbere ya byose, hitamo ibikoresho byiza. Guhitamo ibikoresho byumubiri wa valve biragoye, ariko kandi ntibishobora gusa gutekereza kukibazo cyo kwangirika, bigomba gutekereza kumuvuduko nubushyuhe bwubushyuhe, ubukungu bwumvikana, byoroshye kugura nibindi bintu.
Nugufata umurongo ukurikiraho, niba umurongo uyobora, umurongo wa aluminium, umurongo wa injeniyeri ya plastike, umurongo wa reberi karemano hamwe nubwoko bwose bwa reberi. Niba uburyo buciriritse bubyemerera, ubu ni inzira yo kuzigama.
Na none, mugihe cyumuvuduko muke nubushyuhe, gukoresha ibyuma nkibyingenzi nkibikoresho byingenzi bya valve birashobora kuba byiza cyane mukurinda ruswa.
Byongeye kandi, hejuru yumubiri wa valve nawo ushobora kwangirika kwikirere, ibikoresho rusange byibyuma bigomba koza irangi kugirango birinde.
(a) igikoresho gikoreshwa mu gukora no guhuza valve. Igikoresho kirashobora gutwarwa nintoki, amashanyarazi, pneumatike, hydraulic cyangwa guhuza amasoko yingufu, kandi inzira yo kugenda irashobora kugenzurwa na stroke, torque cyangwa axial. Koresha inyuguti ya F hamwe numubare wimibare ibiri (imibare nindangagaciro zihuye na D3, zegeranye kandi zigabanijwe na 10). Imbaraga za axial zoherejwe muguhuza flange na drayike ikoresheje igikoresho cya disiki igaragarira muri Newton (N). Umwanya wo kuzunguruka woherejwe no guhuza flange na drayike ukoresheje igikoresho cya disiki igaragarira muri metero ya Newton (N “m).
1, urugero,
Ibipimo ngenderwaho byerekana amagambo nubusobanuro bwibikoresho byinshi byahinduwe na valve, kode ya flange hamwe na torque nini ihuye na moteri nini. Ibipimo bya flange bihujwe na valve, imiterere nubunini bwibice bya drive.
Ibipimo ngenderwaho bikurikizwa murwego rwo guhuza ibipimo bya valve kuri valve kumarembo, isi, trottle na diaphragm, kimwe nubunini bwo guhuza ibikoresho bya drayike kumasanduku y'ibikoresho hamwe nagasanduku k'ibikoresho kuri valve.
2. Inyandiko zisanzwe
Ibiteganijwe mu nyandiko zikurikira byinjijwe muri uru rwego mpuzamahanga hifashishijwe. Ibyahinduwe byose (ukuyemo errata) cyangwa ubugororangingo bwerekanwe kumatariki ntibikurikizwa kuri iyi Standard mpuzamahanga. Ariko, impande zombi zumvikanyweho naya mahame mpuzamahanga arashishikarizwa gukora iperereza kuri verisiyo ziyi ***. *** verisiyo zerekana itariki zikoreshwa kuri iyi Standard mpuzamahanga.

3. Amagambo n'ibisobanuro
gutwara
Igikoresho gikoreshwa mu gukora no guhuza valve. Igikoresho kirashobora gutwarwa nintoki, amashanyarazi, pneumatike, hydraulic cyangwa guhuza amasoko yingufu, kandi inzira yo kugenda irashobora kugenzurwa na stroke, torque cyangwa axial.
Ikinyabiziga kinini
Ibisohoka bisohoka birashobora guhindurwa byibuze rimwe kandi birashobora kwihanganira gusunika mugihe icyuma cyimura itara kuri valve.
torque
Umwanya wo kuzunguruka woherejwe no guhuza flange na drayike ukoresheje igikoresho cya disiki igaragarira muri metero ya Newton (N “m).
gusunika
Imbaraga za axial zoherejwe muguhuza flange na drayike ikoresheje igikoresho cya disiki igaragarira muri Newton (N).
Kode ya flange
Koresha inyuguti ya F hamwe nuruhererekane rwimibare ibiri (imibare nindangagaciro zihuye na D3, zegeranye kandi zigabanijwe na 10).
4, flange code ugereranije nini nini kandi nini cyane
Umuhengeri hamwe nigitonyanga kiri mu mbonerahamwe ya 1 byerekana urumuri runini kandi rushobora kwanduzwa binyuze muri flange na actuator yigikoresho cyo gutwara.
Imbonerahamwe 1 Kugereranya torque nini nigiciro cya Flangde no.1
5, ingano ya flange
Flange ihuza ibikorwa na valve nkuko bigaragara ku gishushanyo 1 na mbonerahamwe ya 2.
FIG. 1 Igishushanyo cyo guhuza ibikoresho byo gutwara na valve
Imbonerahamwe 2 Ibipimo bya flange ya actuator ihujwe na valve muri mm
Ikibumbano gihuza igikoresho cyo gutwara na valve kigomba kuba flange ihindagurika hamwe nigitugu giherereye, kandi ingano yacyo igomba kuba ikurikije d2 mu mbonerahamwe ya 2.
Acuator irashobora guhuzwa na valve na sitidiyo. Niba imiyoboro ya sitidiyo ikoreshwa, diameter yimyobo ya sitidiyo igomba guhuza urugero D4 mumeza 2. Urudodo ukurikije GB / T 196.
Uburebure ntarengwa bwumurongo wa valve kugirango utware ibice nkuko bigaragara mu mbonerahamwe ya 2 h1.
Ibipimo by'uruziga rw'inyuma, ukurikije imbonerahamwe ya 2 D1 (ntarengwa).
Kwiga cyangwa umwobo wa bolt bigomba kuba bitangaje umurongo wigikoresho cya disiki ikwirakwizwa. Reba Ishusho 2.
