Chiyambi cha mfundo ya valavu yowunikira

Valvu yowunikira, yomwe imadziwikanso kuti valve yowunikira, valve yowunikira, mfundo yake yogwirira ntchito imachokera makamaka pakutsegula ndi kutseka kwa diski ya valve yokha kuti ilamulire kuyenda kwa njira imodzi ya medium ndikuletsa kubwerera. Izi ndizomwe zikufotokozera mwatsatanetsatane mfundo yogwirira ntchito ya valve yowunikira:

Choyamba, mfundo yoyambira yogwirira ntchito

Mfundo yogwirira ntchito ya valavu yowunikira ikhoza kufotokozedwa motere: pamene cholumikizira (monga madzi, gasi, ndi zina zotero) chikuyenda motsatira njira yokonzedweratu, diski ya valavu imatsegulidwa yokha ndi kupanikizika kwa cholumikizira, zomwe zimathandiza kuti cholumikizira chidutse; Pamene cholumikizira chikuyesera kubwerera m'mbuyo, diski ya valavu imatseka yokha chifukwa cha kupanikizika kwapakati ndi mphamvu yake yokoka, zomwe zimaletsa cholumikizira kuti chisabwerere m'mbuyo.

Chachiwiri, mfundo yeniyeni yogwirira ntchito

Malinga ndi kapangidwe ka valavu yoyezera, mfundo yake yogwirira ntchito ndi yosiyana pang'ono, koma mfundo yoyambira ndi yofanana. Zotsatirazi zimagwiritsa ntchito mavalavu oyezera ozungulira ndi mavalavu oyezera okweza ngati zitsanzo:

1. Valavu yoyezera kusambira

Kapangidwe kake: Disiki ya valavu yowunikira swing imalumikizidwa ndi thupi la valavu kudzera mu hinge mechanism, ndipo imatha kuzunguliridwa momasuka. Disiki nthawi zambiri imakhala yofanana ndi diski ndipo imazungulira mozungulira pini pakati pa mpando.

Mfundo yogwirira ntchito: Pamene sing'anga ikuyenda patsogolo, diski ya valavu imayikidwa pansi pa mphamvu ya sing'anga, ndipo imazungulira mozungulira shaft ya pin kuti sing'anga idutse; Pamene sing'anga ikuyenda mmbuyo, diski ya valavu imayikidwa pansi pa mphamvu ya sing'anga ndi mphamvu yake yokoka, ndipo imazungulira shaft ya pin kuti sing'anga iyende mmbuyo.

2. Valavu yoyezera kukweza

Mawonekedwe a kapangidwe kake: Chophimba cha valavu yoyezera kukweza chimayenda mmwamba ndi pansi motsatira mzere wozungulira. Disiki nthawi zambiri imakhala pamwamba pa mpando wotsekera thupi la valavu ndipo imatha kukwezedwa ndikutsitsidwa momasuka.

Mfundo yogwirira ntchito: Pamene sing'anga ikuyenderera patsogolo, diski ya valavu imakwezedwa ndi kupanikizika kwa sing'anga, ndipo njira imatsegulidwa kuti sing'anga idutse; Pamene sing'anga ikuyenderera kumbuyo, diski ya valavu imachepetsedwa ndi kachitidwe kawiri ka kupanikizika kwa sing'anga ndi mphamvu yake yokoka, ndipo njirayo imatsekedwa kuti sing'anga ibwerere m'mbuyo.

Chachitatu, makhalidwe a ntchito

Ma valve oyesera ali ndi makhalidwe otsatirawa ogwirira ntchito:

1. Kudziyimira pawokha: Valavu yowunikira ndi valavu yodziyimira yokha yomwe sifunikira kulamulira kwakunja kapena kulowererapo kuti ikwaniritse kuyenda kwa njira imodzi ndikuletsa kubwerera kwa madzi.

2. Kutseka: Valavu yotchingira ili ndi magwiridwe antchito abwino otsekera pakati pa diski ndi mpando kuti zitsimikizire kuti cholumikiziracho chitha kupewedwa bwino pamene chikuyenda mobwerera m'mbuyo.

3. Kudalirika: Valavu yowunikira ili ndi kapangidwe kosavuta komanso ntchito yodalirika, ndipo imatha kusunga magwiridwe antchito okhazikika pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito.

Chachinayi, gawo logwiritsira ntchito

Ma valve oyezera amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zamadzimadzi, monga njira zoperekera madzi ndi zotulutsira madzi, njira za HVAC, njira zopangira mafakitale, ndi zina zotero, kuti ateteze kubwerera kwa media ndikuteteza zida ndi machitidwe kuti asawonongeke.

Mwachidule, valavu yowunikira imalamulira kuyenda kwa njira imodzi kwa cholumikizira ndipo imaletsa kubwerera kwa madzi kudzera mu kutsegula ndi kutseka kwa diski ya valavu yokha. Mfundo yake yogwirira ntchito ndi yosavuta komanso yodalirika, ndipo imagwira ntchito yofunika kwambiri m'machitidwe osiyanasiyana amadzimadzi.
