Valavu yowunikira imatanthauza valavu yomwe imatsegula ndikutseka yokha chivundikiro cha valavu kutengera momwe chivundikirocho chimayendera kuti chisabwererenso. Imatchedwanso valavu yowunikira, valavu yolowera mbali imodzi, valavu yobwerera m'mbuyo, ndi valavu yokakamiza kumbuyo. Ntchito ya valavu yowunikira ndi
Valavu yowunikira ndi mtundu wa valavu yodziyimira yokha, ntchito yake yayikulu ndikuletsa kuyenda kwa sing'anga kumbuyo, kuletsa pampu ndi mota yoyendetsera kuti zisabwerere m'mbuyo, komanso kutulutsa sing'anga yowunikira. Cheke ingagwiritsidwenso ntchito kupereka mapaipi a makina othandizira komwe kuthamanga kumatha kukwera pamwamba pa kuthamanga kwa makina.
Kugawa ma valve oyesera
Malinga ndi kapangidwe kake ndi njira yoyikira, valavu yoyezera ikhoza kugawidwa m'magulu:

1. Valavu yowunikira Swing
Chimbale cha valavu yowunikira ma swing ndi chooneka ngati diski ndipo chimazungulira shaft ya valavu yolowera. Chifukwa njira yomwe ili mu valavu ndi yolunjika, kukana kwa kayendedwe ka madzi kumakhala kochepa kuposa kwa valavu yowunikira ma lift. Ndi yoyenera kuyenda pang'ono komanso ma valve osabwerera. Nthawi zambiri pali ma diameter akuluakulu okhala ndi kusintha pafupipafupi, koma sikoyenera kuyenda kwa ma pulsating, ndipo magwiridwe ake otsekera si abwino ngati mtundu wokweza. Ma valve owunikira ma swing amagawidwa m'mitundu itatu: single valve, double valve ndi half valve. Mitundu itatuyi imagawidwa makamaka malinga ndi kukula kwa valavu. Cholinga chake ndikuletsa kuti sing'anga iyime kapena kuyenda m'mbuyo ndikufooketsa hydraulic shock.

2. Valavu yoyezera nyali
Valavu yoyezera yomwe chimbale chake chimasendera pakati pa thupi la valavu. Valavu yoyezera kukweza imatha kuyikidwa pa payipi yopingasa yokha, ndipo mpira wozungulira ungagwiritsidwe ntchito pa diski yayikulu pa valavu yoyezera yaing'ono yokhala ndi mphamvu yayikulu. Mawonekedwe a thupi la valavu yoyezera kukweza ndi ofanana ndi valavu yoyimitsa (yomwe ingagwiritsidwe ntchito mofanana ndi valavu yoyimitsa), kotero mphamvu yake yokana madzi ndi yayikulu. Kapangidwe kake ndi kofanana ndi valavu yoyimitsa, ndipo thupi la valavu ndi diski ndizofanana ndi valavu yoyimitsa. Gawo lapamwamba la valavu ndi gawo la pansi la chivundikiro cha valavu zimakonzedwa ndi manja otsogolera. Manja otsogolera a diski amatha kukwera ndikugwa momasuka m'manja otsogolera a valavu. Pamene sing'anga ikuyenda pansi, ma valavu amatsegulidwa ndi mphamvu ya sing'anga. Pamene sing'anga imayima, ma valavu amatengera okha. Imagwera pampando wa valavu kuti siiyende kumbuyo. Kulunjika kwa njira yolowera ndi yotulukira ya valavu yowongolera yolunjika kumakhala kolunjika ku mbali ya njira ya mpando wa valavu; Valavu yoyezera kukweza yoyimirira ili ndi njira yofanana ya njira yolowera ndi yotulutsira mpweya monga njira ya mpando wa valavu, ndipo kukana kwake kuyenda kwa mpweya ndi kochepa kuposa mtundu wowongoka.

3. Valavu yowunikira disc
Vavu ndi valavu yowunikira yomwe imazungulira shaft ya pini yomwe ili pampando wa valavu. Vavu yowunikira disc ili ndi kapangidwe kosavuta ndipo imatha kuyikidwa pa payipi yopingasa yokha, yokhala ndi magwiridwe antchito osatseka bwino.

4. Valavu yowunikira yomwe ili pamzere
Vavu ndi valavu yomwe imatsetsereka pakati pa thupi la valavu. Vavu yowunikira mkati ndi mtundu watsopano wa valavu. Ndi yaying'ono kukula, yopepuka kulemera, komanso yabwino paukadaulo wokonza. Ndi imodzi mwa njira zopangira mavavu owunikira. Komabe, mphamvu ya kukana madzi ndi yayikulu pang'ono kuposa ya valavu yowunikira yozungulira.
5. Valavu yoyezera kupsinjika
Mtundu uwu wa valavu umagwiritsidwa ntchito ngati valavu yothira madzi ndi nthunzi, ndipo uli ndi ntchito yonse ya valavu yoyezera kukweza ndi valavu yoyimitsa kapena valavu ya ngodya.
