Ma valve monga Bristol BF59/A99 amasonyeza ntchito yabwino kwambiri, ndi mphamvu yogwira ntchito ya 175 PSI ndi mphamvu yoyesera ya 24 bar. Kapangidwe kawo kolimba kamatsimikizira kudalirika pamavuto amphamvu, zomwe zimapangitsa kuti akhale oyenera makina oteteza moto m'nyumba zazitali.
Kutsatira Malamulo ndi Miyezo Yoteteza Moto
Kuonetsetsa kuti malamulo ndi miyezo ya chitetezo cha moto ikutsatira malamulo ndi miyezo ya chitetezo cha moto n'kofunika kwambiri posankha valavu ya payipi ya ngodya ya nyumba zazitali. Malamulowa amakhazikitsa zofunikira zochepa pakugwira ntchito, kukhazikitsa, ndi kukonza, kuonetsetsa kuti makina oteteza moto amagwira ntchito bwino panthawi yamavuto. Kutsatira miyezo imeneyi sikuti kumangowonjezera chitetezo komanso kumatsimikizira kuti eni nyumba ndi oyang'anira nyumba akutsatira malamulo.
Malamulo oteteza moto, monga omwe afotokozedwa ndi National Fire Protection Association (NFPA), amapereka malangizo atsatanetsatane a ma valve a payipi ya ngodya ndi zinthu zina zokhudzana nazo. Mwachitsanzo, NFPA 14 imafotokoza kapangidwe, kuyika, ndi kuyesa makina oimikapo mapaipi ndi mapaipi. Miyezo iyi imatsimikizira kuti ma valve akukwaniritsa miyezo yofunika kwambiri yogwirira ntchito, monga kuyesedwa kwa kuthamanga kwa madzi ndi zofunikira pakuyenda kwa madzi.
Tebulo lotsatirali likuwonetsa zofunikira zazikulu zama valve a payipi ndi makina oimikapo mapaipi:
| Chofunikira | Kufotokozera |

| Malo Ogulitsira Mapaipi | Chotulutsira chilichonse cha payipi cha mainchesi 1.5 kapena chaching'ono chiyenera kukhala ndi zida zokwanira komanso chokonzeka kugwiritsidwa ntchito. |
| Mtundu wa payipi | Makina oimikapo mapaipi okhazikika omwe adayikidwa pambuyo pa Januwale 1, 1981, ayenera kugwiritsa ntchito payipi yolumikizidwa. |
| Kupanikizika | Kuthamanga kwa mphamvu pa nozzle kuyenera kukhala pakati pa 30 psi (210 kPa) ndi 125 psi (860 kPa). |
| Kupereka Madzi | Madzi ocheperako ayenera kukhala malita 100 pamphindi (6.3 l/s) kwa mphindi zosachepera 30. |
| Kuyesa kwa Madzi | Mapaipi ayenera kuyesedwa pa 200 psi (1380 kPa) kwa maola osachepera awiri. |
| Kuyesa kwa Mapayipi | Paipi iyenera kuyesedwa pa mphamvu yosachepera 200 psi (1380 kPa) isanayambe kugwiritsidwa ntchito. |
| Kukonza | Makina a payipi ayenera kufufuzidwa osachepera chaka chilichonse komanso mukatha kugwiritsa ntchito. |
Zofunikira izi zimaonetsetsa kuti valavu ya payipi ya ngodya ndi machitidwe ogwirizana nayo amagwira ntchito modalirika pansi pa mikhalidwe ya kupanikizika kwakukulu. Mwachitsanzo, kuyesa kwa hydrostatic pa 200 psi kumatsimikizira kukhulupirika kwa mapaipi, pomwe kuwunika kwa pachaka kumathandiza kuzindikira mavuto omwe angakhalepo asanafike pachimake.
Kutsatira malamulo kumaphatikizaponso kusankha ma valve omwe amakwaniritsa ziphaso zinazake. Ma valve ambiri apamwamba, monga omwe amapangidwa ndi Yuyao World Fire Fighting Equipment Factory, ali m'gulu la UL ndipo akutsatira miyezo ya ANSI/UL 1468. Ziphasozi zimatsimikizira kuti ma valve ayesedwa mwamphamvu kuti aone ngati ali olimba komanso kuti agwire bwino ntchito.
Mwa kutsatira malamulo ndi miyezo iyi, oyang'anira nyumba angatsimikizire kuti makina awo oteteza moto ali okonzeka kuthana ndi mavuto. Kuyang'anitsitsa ndi kukonza nthawi zonse kumawonjezera kudalirika kwa makinawa, kuteteza miyoyo ndi katundu.
Kulimbitsa Chitetezo cha Moto ndi Valavu ya Paipi Yakumanja
Kufunika kwa Ma Valves Ochepetsa Kupanikizika M'nyumba Zazitali
Nyumba zazitali nthawi zambiri zimakhala ndi kusintha kwakukulu kwa kuthamanga kwa madzi chifukwa cha kutalika kwawo. Kuthamanga kwambiri kumatha kuwononga zida zozimitsira moto kapena kulepheretsa magwiridwe antchito ake.Ma valve ochepetsa kupanikizika (PRVs)kuthetsa vutoli mwa kuchepetsa kuthamanga kwa madzi kufika pamlingo wabwino komanso wofanana. Ma valve awa amatsimikizira kuti madzi operekedwa kudzera mu makina oimikapo madzi amakhalabe mkati mwa malire a ntchito ya zida zolumikizidwa.
Ma PRV ndi ofunikira kwambiri pazipinda zomwe zili pafupi ndi maziko a nyumbayo, komwe kuthamanga kwa madzi kumakhala kwakukulu. Mwa kusunga kuthamanga koyenera, ma valve awa amathandizira kugwira ntchito bwino kwanjira yotetezera motoZimathandizanso kupewa zoopsa zomwe zingachitike chifukwa cha kuyenda kwa madzi mopitirira muyeso. Kuphatikiza ma PRV pamodzi ndi valavu ya payipi ya ngodya kumatsimikizira kuti pali njira yozimitsira moto yoyenera komanso yodalirika, makamaka m'nyumba zazitali.
Kukhazikitsa Koyenera ndi Kufikika
Kukhazikitsa bwino valavu ya payipi ya ngodya ndikofunikira kwambiri pakugwira ntchito kwake. Kusayikidwa bwino kapena kusakhazikika bwino kungayambitse kutuluka kwa madzi kapena kuchepa kwa magwiridwe antchito. Okhazikitsa ayenera kutsatira malangizo a opanga ndi miyezo yamakampani kuti atsimikizire kuti ikugwirizana bwino. Mwachitsanzo, mavalavu ayenera kuyikidwa pamalo okwera omwe amalola ozimitsa moto kulowa mosavuta. Kuyika kumeneku kumachepetsa kuchedwa panthawi yamavuto.
Kufikika mosavuta kumathandizanso kwambiri pakugwira ntchito bwino kwa valavu. Mavalavu oikidwa m'malo ovuta kufikako amatha kulepheretsa ntchito yozimitsa moto. Kulemba zilembo bwino komanso njira zopanda chopinga kumawonjezera kugwiritsa ntchito bwino. Kuphunzitsidwa nthawi zonse kwa ogwira ntchito yomanga nyumba kumatsimikizira kuti akumvetsa komwe valavuyo ili komanso momwe imagwirira ntchito. Kuyika bwino ndi kupezeka mosavuta kumathandiza kuti valavuyo igwire bwino ntchito pakagwa ngozi zamoto.
