Kuyika ma valve a zipata, ma valve a globe ndi ma check valves

Valve yachipata, yomwe imadziwikanso kuti valavu yachipata, ndi valve yomwe imagwiritsa ntchito chipata kuti ilamulire kutsegula ndi kutseka. Imasinthasintha kayendedwe ka mapaipi ndikutsegula ndi kutseka mapaipi posintha magawo a mapaipi. Mavavu a pachipata amagwiritsidwa ntchito kwambiri m'mapaipi okhala ndi zotsegulira zotseguka kapena zotsekedwa kwathunthu. Nthawi zambiri palibe njira yomwe imafunikira pakuyika ma valve pachipata, koma siyingayikidwe mozondoka.

Avalavu ya globendi valavu yomwe imagwiritsa ntchito diski ya valve kulamulira kutsegula ndi kutseka. Posintha kusiyana pakati pa diski ya valve ndi mpando wa valve, ndiko kuti, kusintha kukula kwa gawo lodutsa njira, kutuluka kwapakati kapena njira yapakati imadulidwa. Mukayika valavu yoyimitsa, chidwi chiyenera kuperekedwa kumayendedwe amadzimadzi.
Mfundo yomwe iyenera kutsatiridwa poika valavu yoyimitsa ndi yakuti madzi a m'mipope amadutsa mu dzenje la valve kuchokera pansi kupita pamwamba, omwe amadziwika kuti "otsika ndi otsika", ndipo kubwezeretsanso sikuloledwa.

Onani valavu, yomwe imatchedwanso check valve ndi valve ya njira imodzi, ndi valve yomwe imatsegula ndi kutseka pansi pa kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo kwa valve. Ntchito yake ndikulola sing'anga kuyenda mbali imodzi yokha ndikuletsa sing'anga kubwereranso kwina. Malinga ndi mawonekedwe osiyanasiyana, ma valavu owunika amaphatikiza ma lift, swing ndi ma valve a butterfly clamp. Ma valve okweza amagawidwa m'mitundu yopingasa komanso yoyima. Mukayika valavu yoyang'ana, muyenera kumvetseranso kayendetsedwe ka kayendedwe ka sing'anga ndipo musayike kumbuyo.

Kuyika kwa valve yochepetsera kuthamanga

Valavu yochepetsera kuthamanga ndi valavu yomwe imachepetsa kuthamanga kwa mpweya wolowera kumtunda wofunikira wotuluka kudzera mukusintha ndipo imangosunga chiwongolero chokhazikika podalira mphamvu ya sing'anga yokha.

Kuchokera pamakina amadzimadzi, valavu yochepetsera kupanikizika ndi chinthu chomwe chimatha kusintha kukana kwanuko. Ndiko kuti, posintha malo otsekemera, kuthamanga kwa madzi ndi kinetic mphamvu yamadzimadzi kumasinthidwa, motero kumatulutsa kutaya kwapakati kosiyanasiyana, potero kukwaniritsa cholinga chochepetsera kupanikizika.

Kuyika kwa valve yochepetsera kuthamanga

1. Gulu la valavu yochepetsera vertically lomwe limayikidwa pamwamba limayikidwa pakhoma pamtunda woyenera kuchokera pansi; gulu la valve yochepetsera yopingasa yokhazikika limayikidwa papulatifomu yokhazikika.

2. Gwiritsani ntchito chitsulo chopangidwa ndi mawonekedwe kuti muyike pakhoma kunja kwa ma valve awiri olamulira (omwe amagwiritsidwa ntchito poyimitsa ma valve) kuti apange bulaketi. Chitoliro cholambalalacho chimakakamiranso pa bulaketi ndikuyalidwa.

3. Vavu yochepetsera kuthamanga iyenera kuyikidwa molunjika paipi yopingasa ndipo sayenera kupendekeka. Muvi womwe uli pa thupi la vavu uyenera kuloza komwe kumayenda pakati ndipo sungakhoze kuikidwa chammbuyo.

4. Ma valve oyimitsa ndi magetsi othamanga kwambiri ndi otsika ayenera kuikidwa kumbali zonse ziwiri kuti ayang'ane kusintha kwa mphamvu isanayambe komanso itatha. Kuzama kwa chitoliro pambuyo pa valavu yochepetsera kuthamanga kuyenera kukhala 2 # - 3 # yayikulu kuposa kukula kwa chitoliro cholowera kutsogolo kwa valavu, ndipo chitoliro chodutsa chiyenera kukhazikitsidwa kuti chithandizire kukonza.

5. Chitoliro chofananira cha chitoliro cha diaphragm chochepetsera valavu chiyenera kulumikizidwa ndi payipi yotsika. Mapaipi ocheperako ayenera kukhala ndi ma valve otetezera kuti awonetsetse kuti dongosololi likuyenda bwino.

6. Mukagwiritsidwa ntchito pochotsa nthunzi, chitoliro cha ngalande chiyenera kuikidwa. Kwa machitidwe a mapaipi omwe ali ndi zofunikira zoyeretsa kwambiri, fyuluta iyenera kuikidwa kutsogolo kwa valve yochepetsera kuthamanga.

7. Pambuyo pa gulu la valve kuchepetsa kupanikizika, valavu yochepetsera mphamvu ndi valavu yotetezera iyenera kuyesedwa, kuthamangitsidwa ndi kusinthidwa malinga ndi zofunikira za mapangidwe, ndipo zosintha ziyenera kulembedwa.

8. Pamene mukutsuka valavu yochepetsera kuthamanga, tsekani valavu yochepetsera mphamvu ndikutsegula valavu yothamanga kuti mugulitse.

Kuyika msampha

Ntchito yaikulu ya msampha wa nthunzi ndikutulutsa madzi osungunuka, mpweya ndi mpweya wa carbon dioxide mu nthunzi yotentha mofulumira; pa nthawi yomweyo, akhoza basi kuteteza nthunzi kutayikira pamlingo waukulu. Pali mitundu yambiri ya misampha, iliyonse ili ndi luso losiyana.

Malinga ndi mfundo zosiyanasiyana zogwirira ntchito za misampha ya nthunzi, zitha kugawidwa m'magulu atatu awa:

Zimango: Kuchita molingana ndi kusintha kwa mulingo wa condensate mumsampha, kuphatikiza:

Mtundu woyandama: Choyandamacho ndi malo otsekedwa opanda dzenje.

Mtundu woyandama wotsegulira m'mwamba: Choyandamacho chimakhala chowoneka ngati mbiya ndipo chimatseguka m'mwamba.

Mtundu woyandama wopita pansi: Choyandamacho chimakhala chooneka ngati mbiya ndipo chotsegulacho chili pansi.

Mtundu wa Thermostatic: umagwira ntchito molingana ndi kusintha kwa kutentha kwamadzimadzi, kuphatikiza:

Tsamba la Bimetallic: Chinthu chodziwika bwino ndi pepala la bimetallic.

Mtundu wa mphamvu ya nthunzi: Chinthu chodziwikiratu ndi mvuvu kapena cartridge, yomwe imadzazidwa ndi madzi osasunthika.

Mtundu wa Thermodynamic: Ntchito yotengera kusintha kwa mphamvu yamadzimadzi.

Mtundu wa Disc: Chifukwa cha mitundu yosiyanasiyana yamadzimadzi ndi gasi pansi pa kupanikizika komweko, zovuta zosiyanasiyana zosinthika komanso zosasunthika zimapangidwira kuyendetsa valavu ya disc kuti isunthe.

Mtundu wa Pulse: Pamene condensate ya kutentha kosiyana idutsa muzitsulo zamtundu wa throttle orifice plates, zovuta zosiyana zimapangidwira pakati pa matabwa awiri a throttle orifice plates, kuyendetsa valavu kuti isunthe.

Kuyika msampha

1. Ma valve oyimitsa (ma valve oyimitsa) ayenera kuikidwa kutsogolo ndi kumbuyo, ndipo fyuluta iyenera kuikidwa pakati pa msampha ndi valavu ya kutsogolo kuti muteteze dothi m'madzi a condensate kuti asatseke msampha.

2. Chitoliro choyendera chiyenera kuikidwa pakati pa msampha ndi valve yoyimitsa kumbuyo kuti muwone ngati msampha ukugwira ntchito bwino. Ngati nthunzi yochuluka imatuluka mukamatsegula chubu choyendera, msampha umawonongeka ndipo umafunika kukonzedwa.

3. Cholinga chokhazikitsa chitoliro chodutsa ndikutulutsa madzi ambiri osungunuka panthawi yoyambira ndikuchepetsa kutsitsa kwa msampha.

4. Pamene valavu yokhetsa imagwiritsidwa ntchito kuchotsa condensate kuchokera ku zipangizo zotenthetsera, iyenera kuikidwa m'munsi mwa zipangizo zotenthetsera kuti chitoliro cha madzi a condensate chibwerere vertically ku valve drain kuti ateteze madzi akuchuluka muzitsulo zotentha.

5. Malo oyikapo ayenera kukhala pafupi ndi ngalande momwe zingathere. Ngati mtunda uli patali kwambiri, mpweya kapena nthunzi zimatha kuwunjikana mu chitoliro chachitali chopyapyala kutsogolo kwa msampha.

6. Pamene chitoliro chachikulu cha nthunzi chopingasa chili chotalika, nkhani za ngalande ziyenera kuganiziridwa.
