Valve y'umupira ya PVC vs Icuma kidashonga, Icuma cya karuboni - Uko wahitamo

Guhitamo Valve y'umupira ikwiye: PVC vs. Icyuma, Icyuma kidashonga, n'icyuma cya karuboni – Ibyo nize mu ruganda

Mu myaka 15 ishize, nasimbuje uturindantoki twinshi kuruta uko nemera. Kandi mu by'ukuri? Ibyinshi mu bibazo biterwa n'ikosa rimwe: guhitamo ibikoresho bitari byo. AValve y'umupira ya PVCbishobora gukora neza ku gipimo cy'imiti - ariko shyira ku murongo w'umwuka, maze uzagira akajagari gashongeshejwe mu minota icumi. Ku rundi ruhande, harivalve y'umupira w'icyuma cya karubonini ikomeye kandi ihendutse, ariko uyireke hanze mu mvura mu gihe cy'igihe runaka, maze izamera nk'aho ari icyuma cyangiritse.

Reka rero nkubwire icyo ntekerezaho mu by'ukuri iyo nhisemo hagatiPVC, icyuma rusange, icyuma kitagira umwanda, navalve z'umupira w'icyuma cya karuboniNta kintu gifatika. Ni iki gikora, ni iki kidakora, n'aho nabonye abantu batwikwa.

Valve y'umupira wa PVC: Ni nziza cyane ku miti, nta kamaro ifite ku bushyuhe

Nigeze gufasha iduka rito ricuruza aside gukora ku buryo bworoshye. Bashakaga ko ihendutse, bityo twakoreshejeValve y'umupira ya PVChamwe n'intego z'ubumwe bw'ukuri. Ibyo byabaye mu myaka itanu ishize - biracyakora. Kuki? Kubera ko PVC itita ku aside hydrochloric cyangwa sodium hypochlorite. Ifite ubudahangarwa ku bwoko bwinshi bw'ibinyabutabire bikaze.

Icyo nkunda:

• Ubudahangarwa bw'ingufu budasanzwe ku giciro.

• Yoroshye bihagije ku buryo yafata n'ukuboko kumwe.

• Nta kibazo cya galvanic iyo gifatanye n'umuyoboro wa PVC cyangwa CPVC.

Icyo nanga:

• Ubushyuhe. Hari ikintu kiri hejuru ya 140°F (60°C) maze valve ikagenda yoroha. Ikagwa munsi y'ubukonje? Iracika intege. Nabonye valve ya PVC yamenetse nk'ikirahure nyuma y'ubukonje butunguranye.

• Umuvuduko muke - komeza munsi ya psi 230 cyangwa hafi yaho.

• Izuba ryica PVC isanzwe. Niba uyikoresha hanze, tanga amafaranga y'inyongera kuri UV-stabilized.

Aho mbisobanura:

Gutunganya amazi, gukoresha imiti, ubworozi bw'amafi, gukora imiyoboro y'amazi yo mu bidendezi. Ntuzigere ushyushya amavuta, ntuzigere ushyira umwuka urenze 150 psi.

Valve y'umupira w'icyuma kidashonga - Ifarashi y'umukino (304 vs. 316)

Iyo nza kuba mfite ubwoko bumwe bwa valve mu ikamyo yanjye, byaba arivalve y'umupira w'icyuma kidashonga. Byaba byiza 316 bita stainless. Kuki? Kubera ko ikora hafi ya byose uretse aside hydrochloric ishyushye hamwe na oxidizers nke mbi cyane.

Ndibuka uruganda rw'ibiribwa rwahoraga rusimbura uturindantoki tw'icyuma cya karuboni ku muyoboro ushyushye wa CIP (usukuye ahantu). Uturindantoki twangizaga imbere tukanduza ibicuruzwa. Twahinduye uturindantoki 316 tw'umupira utagira umugese - ikibazo cyarashize. Ubuso bworoshye ntibufata bagiteri, kandi amazi atwika ntagira icyo atwara.

Ibyiza ushobora kwishingikirizaho:

• Ubushyuhe buri hagati ya -20°F na 450°F (hamwe n'intebe zisanzwe za PTFE). Ubwoko bwihariye bw'ubushyuhe bwinshi burazamuka kurushaho.

• Igipimo cy'umuvuduko kigera kuri psi 1.000–6.000+ bitewe n'imiterere.

• 316 SS ifite molybdenum - iyo ni inshuti yawe ku mazi yo mu nyanja cyangwa ahantu harimo chloride.

Ibyiza (ibiganiro nyabyo):

• Birahenze. Valve y'umupira ya santimetero 2 na santimetero 316 ishobora kugura inshuro 5-10 kuri valve ya PVC.

• Ikomeye. Ibikoresho byawe by'imiyoboro bigomba kuba bikomeye.

• 304 stainless ishobora kwangirika muri serivisi ya chloride ishyushye - Nabimenye mu buryo bugoye ku mushinga wo ku nkombe. Koresha 316 ku kintu cyose kiri hafi y'amazi y'umunyu.

Itegeko ryanjye:

Iyo amazi yangiritse, ashyushye, cyangwa akeneye kuba asukuye (ibiribwa/imiti), ngira icyuma gikingira. Iyo amafaranga make kandi amazi adashyushye cyane, nshobora gutekereza ku byuma bya karuboni.

Valve y'icyuma cya karuboni - Irakomeye, irahendutse, ariko iragwa ingese

Reka dusobanukirwe neza: avalve y'umupira w'icyuma cya karubonintabwo ari ifumbire. Nabonye abahanga bashya bafata "icyuma ni icyuma" bagashyira valve y'icyuma cya karuboni ku muyoboro w'umwuka utose. Nyuma y'amezi atandatu, kirafatwa cyangwa kikava mu mubiri.

Nubwo bimeze bityo, icyuma cya karuboni gifite umwanya wacyo - gikomeye. Mu nganda zitunganya peteroli, imiyoboro ya gaze karemano, na sisitemu zo gushonga kw'umwuka, icyuma cya karuboni ni cyo gikoreshwa mu buryo bwa buri gihe. Gihangana n'umuvuduko mwinshi (kugeza kuri psi 1,500+) n'ubushyuhe bugera kuri dogere 800 Fahrenheit hamwe n'uburyo bukwiye bwo kugitunganya.

Ibyiza:

• Ikomeye cyane kurusha PVC.

• Igura make kurusha iy'icyuma kidashonga.

• Irasudira, irakoreshwa mu machine, byoroshye kuyifata mu bunini bunini (kugeza kuri 48”).

Ikibi (kandi ni kibi):

• Ingese. Igaragara ku bushuhe, ubushuhe, cyangwa aside iyo ari yo yose? Uzabona imirongo y'umukara mu byumweru bike.

• Ntabwo ari iby'amazi yo mu nyanja, chlorine, cyangwa aside.

• Ibyuma bisanzwe bya karuboni biracika intege munsi ya -20°F – Nakuyemo valves zavunitse mu gikoresho gikonjesha. Koresha ubushyuhe buke (LF2) niba bikonje.

Aho nyikoresha:

Gazi yumye, amavuta ya lisansi, umwuka w'umwuka (wuzuye cyangwa ushyushye cyane), umwuka wumye, n'imiyoboro y'amazi y'umuriro iguma yumye cyangwa itwikiriwe imbere.

Valve y'umupira w'icyuma rusange - ibyo bivuze iki?

Ijambovalve y'umupira w'icyumaNtibisobanutse neza. Hari igihe bivuze icyuma cya karuboni. Hari igihe kiba icyuma gito cyane nk'icyuma cya A105. Kandi rimwe na rimwe - witondere - ni valve y'icyuma ihendutse kandi ifite ubuziranenge buteye amakenga.

Muri rusange mfata "icyuma gifunga umupira" nk'uburyo buhendutse bwo gukoresha icyuma cya karuboni. Ni byiza ku buryo kidashonga, gifite umuvuduko muto cyangwa uri hagati. Tekereza kuri psi 300–1.500, ubushyuhe buri munsi ya dogere 400 Fahrenheit, amazi meza cyangwa amavuta. Ariko niba ufite ibyago byo kwangirika, jya kuri "stainless" cyangwa nibura usabe ubwoko bwa epoxy.

Urugero rumwe: sisitemu yo gushyushya ububiko ikoresha amazi ashyushye. Bakoresheje valve z'icyuma rusange zidafite igitambaro. Nyuma y'imyaka ibiri, hagaragaye imyobo y'amazi. Yasimbuwe n'umuringa (cyangwa ifumbire) maze irakemuka. Ihame: menya icyo "icyuma" bisobanura mu by'ukuri.

Uko Nhitamo Mu by'ukuri - Uburyo Bworoshye bwo gufata ibyemezo

Ibagirwa ameza maremare gato. Dore icyo numva mu mutwe wanjye iyo umuntu ansabiye inama yo gukoresha valve y'umupira:

1. Amazi ni iki?

   • aside, caustic, amazi y'umunyu, chlorine →PVC(niba ubushyuhe buri munsi ya 140°F) cyangwa316 idafite icyuma gikingira(niba hari ubushyuhe bwinshi/umuvuduko mwinshi).

   • Amavuta, gaze, umwuka wumutse →Icyuma cya karubonicyangwa icyuma rusange.

   • Ibiryo, inzoga, imiti →Icyuma kidasembuye, nta kibazo.

2. Bishyushye gute?

   • Hejuru ya 140°F? Nta PVC.

   • Hejuru y'ubushyuhe bwa 450°F? Intebe zisanzwe zitagira umugese (PTFE) zirananirwa. Ukeneye icyuma cya karuboni gifite intebe zidasanzwe (PEEK, icyuma).

   • Munsi ya 32°F? PVC iracika intege - koresha icyuma cyangwa ifumbire.

3. Igitutu kingana iki?

   • Kurenga psi 230 → kwibagirwa PVC.

   • Irenga 1,500 psi → icyuma cya karuboni cyangwa icupa ry'icyuma kitagira umugese.

4. Ahantu ho hanze cyangwa hatose?

   • Imvura, ubushuhe, inkombe → koresha ibikoresho bitanduye (316 niba biri hafi y'umunyu). Ibyuma bya karuboni bizagwa vuba keretse bisizwe irangi ryiza kandi bigakorwaho buri gihe.

5. Igenzura ry'uko ingengo y'imari ihagaze

   • PVC ihendutse ariko ni nke.

   • Icyuma cya karuboni ni cyo gikurikiraho - agaciro keza kuri serivisi zumutse.

   • Imashini ikoresha ibyuma bitagira umugese irahenze ariko imara imyaka ibarirwa muri za mirongo. Nasimbuye imashini zikoresha ibyuma bitagira umugese zari zimaze imyaka 30 zikora neza.

Amasomo make yo mu ishuri ry’imikino ikomeye

• Ntukavange ibyuma utabanje gutekereza.Iyo uhuje valve y'icyuma kidashonga n'umuyoboro w'icyuma cya karuboni mu buryo butose, uzagira ingese ya galvanic ku migozi. Koresha dielectric unions.

• Insinga za PVC zirapfa kwihuta.Nabonye uturindantoki twa PVC twafashwe cyane ducika aho duhuriye. Koresha kaseti ya PTFE hanyuma uhagarare iyo ifashe neza – ntabwo ari “gorilla tight.”

• Buri gihe reba ibikoresho by'intebe.Valve y'icyuma kidashonga ifite intebe za Buna-N ntishobora kwihanganira ubushyuhe bwinshi, nubwo umubiri waba ubyifuza. PTFE (Teflon) niyo ikoreshwa neza kurusha izindi.

• Komeza ugire ikindi kintu.Nategereje ibyumweru bitandatu kugira ngo mbone valve yihariye y'umupira w'icyuma. Niba ari igikorwa cy'ingenzi, shyiramo ikindi kintu gisigaye - cyane cyane ku byuma bitarangwamo ifu cyangwa karuboni mu bunini budasanzwe.

Mu gihe ushidikanya, andika ubushyuhe bwawe ntarengwa, ubushyuhe bw'umuvuduko, imiterere y'amazi, n'umuvuduko w'amazi. Hanyuma hamagara umucuruzi w'amazi umubaze uti “ni iki washyira ku ipompo yawe?” Abenshi bazaguha igisubizo cy'ukuri - kandi icyo gisubizo gikunze kuba kirimo imashini ifunga icyuma gifunga icyuma gifunga icyuma niba ingengo y'imari ibikwemerera.
