Mafotokozedwe ndi mitundu ya valavu yoyikidwayo sizikukwaniritsa zofunikira pa kapangidwe kake.
Mwachitsanzo, mphamvu ya valavu ndi yocheperako kuposa mphamvu ya mayeso a dongosolo; valavu ya chipata cha chitoliro cha nthambi ya madzi pamene m'mimba mwake wa chitoliro ndi wocheperako kapena wofanana ndi 50mm; chowuma ndi chokwezera chotenthetsera madzi otentha; ndipo chitoliro choyatsira moto chimagwiritsa ntchito.valavu ya gulugufe.
Zotsatira zake: zimakhudza kutsegula ndi kutseka kwabwinobwino kwa valavu ndikusintha kukana, kupanikizika ndi ntchito zina. Ngakhale kuyambitsa kugwira ntchito kwa dongosolo, kuwonongeka kwa valavu kumakakamizika kukonzanso.
Miyeso: Dziwani bwino momwe ma valve osiyanasiyana amagwiritsidwira ntchito, ndipo sankhani zofunikira ndi mitundu ya ma valve malinga ndi zofunikira pa kapangidwe kake. Kupanikizika kwapadera kwa valavu kuyenera kukwaniritsa zofunikira za kuthamanga kwa mayeso a dongosolo. Malinga ndi malamulo omangira: valavu yoyimitsa iyenera kugwiritsidwa ntchito pamene m'mimba mwake wa payipi ndi wochepera kapena wofanana ndi 50mm; valavu ya chipata iyenera kugwiritsidwa ntchito pamene m'mimba mwake wa payipi ndi woposa 50mm. Madzi otentha otentha otentha, valavu yowongolera yoyima iyenera kugwiritsidwa ntchito valavu ya chipata, pampu yamadzi yamoto siyenera kugwiritsa ntchito valavu ya gulugufe.

Zipangizo zazikulu, zida ndi zinthu zomwe zimagwiritsidwa ntchito pomanga sizili ndi zikalata zowunikira khalidwe laukadaulo kapena satifiketi yazinthu zomwe zikugwirizana ndi miyezo yadziko kapena ya nduna yomwe ilipo.
Zotsatira zake: khalidwe la polojekiti yosakwanira, ngozi zomwe zingachitike, sizingachitike pa nthawi yake, ziyenera kukonzedwanso ndikukonzedwanso; zomwe zimapangitsa kuti ntchito yomanga ichedwe komanso kuti anthu ogwira ntchito ndi zinthu zina ziwonjezeke.
Miyeso: Zipangizo zazikulu, zida ndi zinthu zomwe zimagwiritsidwa ntchito mu ntchito zoperekera madzi ndi kutentha ziyenera kukhala ndi zikalata zowunikira khalidwe la chinthu kapena ziphaso zomwe zikugwirizana ndi miyezo yomwe yaperekedwa ndi boma kapena Unduna; pakadali pano, dzina la chinthu, mtundu wake, tsatanetsatane wake, khodi ya dziko lonse ya khalidwe, tsiku lotumizira, dzina la wopanga ndi malo ake, satifiketi yowunikira kapena khodi iyenera kufotokozedwa.

Valavu yozungulira
Zotsatira zake: valavu yofufuzira, valavu yothira mpweya, valavu yochepetsera mpweya, valavu yowunikira mpweya ndi mavalavu ena ali ndi njira yolunjika, ngati atayikidwa mozondoka, valavu yothira mpweya imakhudza momwe ntchitoyo imagwirira ntchito komanso moyo wake; valavu yochepetsera mpweya sigwira ntchito konse, valavu yowunikira mpweya ingayambitsenso ngozi.
Miyeso: valavu yodziwika bwino, yokhala ndi chizindikiro cholozera pa thupi la valavu; ngati sichoncho, iyenera kuzindikirika bwino malinga ndi mfundo yogwirira ntchito ya valavu. Mphepete mwa valavu yoyimitsa ndi yosagwirizana, madziwo ayenera kuwalola kudutsa mkamwa mwa valavu kuchokera pansi kupita pamwamba, kuti kukana kwa madziwo kukhale kochepa (kotsimikiziridwa ndi mawonekedwe), kusunga ntchito yotseguka (chifukwa cha kupanikizika kwapakati), kutseka sing'anga sikukakamiza kulongedza, kukonza kosavuta. Ichi ndichifukwa chake valavu yoyimitsa singathe kukhazikika.

Valavu sichita zotetezera kutentha ndi njira zoziziritsira
Miyeso: ma valve ena ayeneranso kukhala ndi zida zotetezera zakunja, izi ndi zotetezera kutentha ndi zoteteza kuzizira. Nthawi zina mapaipi a nthunzi oteteza kutentha amawonjezeredwa ku gawo lotetezera kutentha. Ndi valavu yamtundu wanji yomwe iyenera kutetezedwa kapena kuzizira, malinga ndi zofunikira pakupanga. Mwachidule, pomwe cholumikizira mu valavu chimachepetsa kutentha kwambiri, chidzakhudza magwiridwe antchito opanga kapena kuzizira valavu, chimafunika kutetezedwa, ngakhale kutsatira kutentha; pomwe valavu yawonekera, yotsutsana ndi kupanga kapena kuyambitsa chisanu ndi zochitika zina zoyipa, ndikofunikira kusunga kuzizira. Zipangizo zotetezera kutentha zimaphatikizapo asbestos, thonje la slag, ubweya wagalasi, perlite, nthaka ya diatom, vermiculite; zida zotetezera kuzizira zimaphatikizapo cork, perlite, thovu, pulasitiki, ndi zina zotero.

Valavu yotulutsira madzi sinayikidwe ndi njira yodutsa
Miyeso: ma valve ena, kuwonjezera pa zida zotetezera zofunika, komanso ali ndi chodulira ndi chida chodulira. Choduliracho chimayikidwa kuti chithandize kukonza chotchingira madzi. Ma valve ena, alinso ndi chodulira. Kuyika chodulira kumadalira momwe valavu ilili, kufunika kwake, ndi zofunikira pakupanga.

Chodzaza sichinasinthidwe nthawi zonse
Miyeso: valavu yosungiramo zinthu, zina zodzaza sizili bwino, zina sizikugwirizana ndi kugwiritsa ntchito zida zolumikizira, zomwe zimafunika kusintha chodzaza.
Valavu imayang'anizana ndi mitundu yosiyanasiyana ya zinthu zosiyanasiyana, ndipo kalata yodzaza nthawi zonse imakhala yodzazidwa ndi mizu wamba ya mbale, koma ikagwiritsidwa ntchito, kulongedza kuyenera kusinthidwa kuti kugwirizane ndi njira yolumikizirana.
Mukasintha chodzaza, kanikizani mozungulira ndi mozungulira. Cholumikizira chilichonse cha m'chiuno chili madigiri 45, ndipo cholumikizira cha mphete ndi mphete chili madigiri 180. Kutalika kwa cholumikizira kuyenera kuganizira malo opitira kukanikiza chivindikiro, ndipo pakadali pano, gawo la pansi la chivindikiro liyenera kukhala ndi kuzama koyenera, komwe nthawi zambiri kungakhale 10-20% ya kuzama konse kwa chipinda cholumikizira.
Kupatula apo, Tianjin Tanggu Water Seal Valve Co., Ltd. ndi valavu yolimba ya mpando yotsogola kwambiri yothandizira mabizinesi, zinthuzo ndi valavu ya gulugufe yolimba ya mpando,valavu ya gulugufe,valavu ya gulugufe yozungulira ya flange iwiri, flange iwirivalavu ya gulugufe yodabwitsa, valavu yolinganiza,vavu yowunikira mbale ziwiri, Y-Strainer ndi zina zotero. Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timadzitamandira popereka zinthu zapamwamba kwambiri zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve ndi zolumikizira zathu zosiyanasiyana, mutha kutidalira kuti tikupatseni yankho labwino kwambiri pamakina anu amadzi. Lumikizanani nafe lero kuti mudziwe zambiri za zinthu zathu komanso momwe tingakuthandizireni.
