Masisitimu emazuva ano ekudzima moto anotsamira pakusimba kwemvura yakadzikama uye yakachengeteka kuti ishande nemazvo. Pressure Regulating Valves (PRVs) yakakosha mukuchengetedza chiyero ichi. A Pressure Regulating Valve inogadzirisa kuyerera kwemvura kuti itsigire mutsauko mukumanikidza kunopinza, kuve nechokwadi kugadzikana kwehurongwa. Aya mavharuvhu akakosha mumaindasitiri akadai sekudzivirira moto uye kurapwa kwemvura, uko mitemo yakasimba yekuchengetedza inoda kushanda kwakavimbika.
Bazi reUS reMagetsi rakaisa mari inosvika mamirioni makumi matatu nemasere emadhora muzvirongwa zvekusimudzira masisitimu ekugovera mvura mumaindasitiri, richisimbisa kukosha kuri kuwedzera kwePRVs kuchengetedza nekubudirira.
Iko kukura kutorwa kwePRVs kunofambiswawo nekuwedzera kwemafuta uye gasi chikamu, uko kwakanyatso kudzvanywa mutemo kwakakosha. Nekudzivirira pamusoro-kudzvinyirira, mavharuvhu ePRV anochengetedza zvakakosha sengemoto hydrant valveuyeoblique valve, kuve nechokwadi chekugara uye kuvimbika. Uyezve,mavharuvhu ekumanikidzazvinochinjika zvakanyanya, zvichiita kuti zvive zvakakosha mukugadzirwa kwezvivakwa zvemazuva ano, zvakaomarara. Yuyao World Fire Fighting Equipment Factory inodada nekupa kune iyi yakakosha indasitiri ine zvemhando yepamusoro mhinduro.

Kunzwisisa Kudzvinyirira Kudzora Mavhavha muMoto Suppression Systems
Chii Chinonzi Pressure Regulating Valves?
Pressure Regulating Mavhavhamidziyo yakasarudzika yakagadzirirwa kudzora nekuchengetedza kudzvinyirirwa kwemvura mukati mekudzivirira kwemoto masisitimu. Aya mavharuvhu anovimbisa kuti dzvinyiriro yemvura inoramba ichienderana, zvisinei nekushanduka kweiyo system inlet pressure. Nekuita izvi, vanobatsira masisitimu ekudzima moto anoshanda zvinobudirira uye zvakachengeteka mumamiriro ese akajairwa uye ekukurumidzira.
Mukutaura kwehunyanzvi, mavharuvhu aya anowira pasi pemapoka akati wandei zvichienderana nekushanda kwawo. Semuyenzaniso:
- Kudzora Mavharuvhukuderedza dzvinyiriro yemvura yakadzika kune imwe kukosha pasi pemamiriro ese ari kuyerera uye asiri kuyerera, sekutsanangurwa kwazvinoitwa neNFPA 20.
- Pressure Regulating Deviceszvakagadzirirwa kuderedza, kudzora, kana kudzikamisa dzvinyiriro yemvura, sezvinotsanangurwa muNFPA 14.
- Mavharuvhu Anoyamura Kudzvinyirirashandura yakawandisa mvura kudzikamisa kumanikidza kuvaka muhurongwa, kuve nechokwadi chekuchengetedza uye kuvimbika.
| Specification Type | Tsanangudzo |
|---|---|
| Pressure Control Valve | Inoderedza dzvinyiriro yemvura yakadzika pasi pemamiriro ekuyerera uye asina kuyerera. |
| Pressure Regulating Devices | Inogadzirisa kana kudzora kumanikidzwa kwemvura mumasisitimu ekudzivirira moto. |
| Pressure Relief Valve | Diverts liquid kudzikamisa yakawandisa pressure musystem. |
Aya mavharuvhu anonyanya kukosha muzvivakwa zvepamusoro-soro, uko misiyano yekumanikidza pakati pepasi inogona kuunza matambudziko. Nekugadzirisa idzi mutsauko, Pressure Regulating Valves inodzivirira zvakakosha senge moto sprinklers uye hydrants kubva mukukuvara kunokonzerwa ne-over-pressurization.
Mavharuvhu Anodzora Kumanikidza Anoshanda Sei?
Pressure Regulating Valves inoshanda nekugadzirisa kuyerera kwemvura kuti ichengetedze yakagadzikana nhanho yekumanikidza. Vanoshandisa nzira dzemukati, dzakadai sezvitubu uye diaphragms, kuti vanzwe uye vapindure kune kuchinja kwekupinda mukati. Kana iyo inlet pressure ichikwira pamusoro pechido chaunoda, vheji inoderedza kuyerera kuunza kudzvanywa kudzokera kunzvimbo yakatarwa. Sezvineiwo, kana iyo inlet yekumanikidza inodonha, vharafu inobvumira mvura yakawanda kuti iyerere nepakati, ichiva nechokwadi chekuenderana kudzika kwemvura.
Kuedzwa uye kuchengetedzwa kwemavharuvhu aya kwakakosha pakushanda kwavo. Zvidzidzo zvakaratidza kuti kutadza muPressure Regulating Valves kunogona kutungamira kune njodzi, zvichiita kuti ive iyo inotungamira yekutadza kudzima system kutadza. Kugara uchiyedzwa kunovimbisa kuti mavharuvhu aya anoita zvakavimbika pasi pemamiriro ese akajairwa uye ekukurumidzira.
Mumasisitimu ekudzivirira moto, mavharuvhu aya anoita basa rakakosha mumasisitimu epipepipe uye otomatiki moto sprinklers. Ivo vanodzora kudzvanywa muzvikamu zvakawanda, kuve nechokwadi chekuti mvura inosvika pamoto pakumanikidzwa kwayo. Kugona uku kunoita kuti zvive zvakakosha pakudzivirira moto kwemazuva ano, kunyanya mumagadzirirwo akaomarara ezvivakwa.
Cherechedza:Kuisa kwakaringana uye kuenzanisa kwePressure Regulating Valves kwakakosha pakuita kwavo. Kudyidzana nevagadziri vanovimbwa vakaita seYuyao World Fire Fighting Equipment Factory inova nechokwadi chekuwana mavharuvhu emhando yepamusoro anoenderana nezvinodiwa zvekuvaka.
Kukosha Kwekudzvanyirira Kudzora Mavharuvhu mune Yemazuvano Moto Kudzvanywa
Kuve nechokwadi chekusagadzikana kweMvura Kudzvinyirira
Kuchengetedza kupindirana kwemvura kunokosha pakushanda kunobudirira kwezvirongwa zvekudzivirira moto.Pressure Regulating Mavhavhaita basa rakakosha mukuita izvi nekugadzirisa mafambiro emvura kuti atsigire kuchinjika kwekumanikidza kwekupinda. Izvi zvinovimbisa kuti mvura inosvika pamidziyo yekudzimisa moto, senge masprinklers uye mahydrants, pakumanikidza kwakaringana kunodiwa kurwisa moto zvinobudirira.
Nhoroondo data inosimbisa kukanganisa kwekumanikidza kudzorwa pahurongwa hwemvura. Semuyenzaniso:
- Muna 1971, Washington Suburban Sanitary Commission yakaita ongororo inosanganisira 2,400 dzimba dzekugara.
- Kushandiswa kwemvura inoderedza mavharuvhu kwakaguma ne30% kuderedza kushandiswa kwemvura munaOctober naNovember, uye kuderedzwa kwe37% muna December.
Izvi zvinoratidza kuti maPRV haangotsigire sei kudzvinyirirwa kwemvura asiwo anovandudza mashandiro ehurongwa. Mumagadzirirwo ekudzivirira moto, kuwirirana uku kunovimbisa kuti mvura inounzwa yakavimbika, zvisinei nekusiyana kwekureba kwekuvaka kana mamiriro ekupa mvura.
Kudzivirira Kuwedzeredza-Kudzvinyirira uye Kukuvadza KweSistimu
Kunyanya-kudzvanyirira kunoisa njodzi yakakura kumasisitimu ekudzima moto, izvo zvinogona kutungamira mukutadza kwemidziyo uye kuchengetedzeka kwakaringana.Pressure Regulating Mavhavhaita sechidziviriro nekudzivirira yakawandisa kumanikidza kuvaka. Ivo vanogadzirisa kuyerera kwemvura kuchengetedza zvakakosha zvinhu, senge zvinosasa moto uye standpipes, kubva mukukuvadzwa kunokonzerwa nekumanikidza kwakanyanya.
Zvidzidzo zvemumunda zvakasimbisa kushanda kwePRV mukuderedza njodzi idzi. Nguva yekuongorora yemwedzi makumi matatu yakaratidza huwandu hwekukundikana kwe 0.4% chete pagore, ine 95% yekuvimba. Regression ongororo yakaratidza zvakare kuti maPRV anove akavimbika nekufamba kwenguva, achisimbisa kusimba kwavo uye kugona kwekudzivirira.
Iyo National Board Inspection Code inosimbisa kukosha kwePRVs semutsara wekupedzisira wedziviriro mune dzakamanikidzwa masisitimu. Nekudzikamisa kudzvanywa, mavharuvhu aya anovimbisa kuchengetedzwa kwemidziyo nevashandi. Izvi zvinoita kuti dzive dzakakosha kune dzemazuva ano dzekudzivirira moto masisitimu, uko kuvimbika kwakakosha.
Kuvandudza Kuchengeteka uye Misangano Yekutevedzera Mayero
Chengetedzo uye kuteedzera kuteedzera kuri musimboti wemazuva ano wekudzimisa moto system dhizaini. Pressure Regulating Valves inosimudzira kuchengetedzwa nekuona kuti kudzvanywa kwemvura kunoramba kuri mukati memiganhu yakachengeteka, kuderedza njodzi yetsaona panguva yenjodzi yemoto. Basa ravo rinonyanya kukosha muzvivakwa zvepamusoro-soro, uko kudzvanywa kwakasiyana pakati pepasi kunogona kugadzira mamiriro ane njodzi kune vese varimo uye vanodzima moto.
Mitemo yemitemo inowedzera kusimbisa kukosha kwePRVs. Iyo National Fire Protection Association (NFPA) yakagadzira akati wandei nhungamiro:
- NFPA 20 inorayira kushandiswa kwePRV kuchengetedza masisitimu kubva mukudzvinyirira zvakanyanya, kunyanya mumasisitimu epombi ecentrifugal.
- NFPA 13 inoda zvivakwa zvekuyedza kuyerera kwePRVs, kuve nechokwadi chekuvimbika kwavo mumamiriro ekukurumidzira.
- Iyo 1999 Edition yeNFPA 13 yakaunza inosungirwa kuongororwa PRV zvinodiwa, kusimbisa basa ravo mukuchengetedza mitemo yekuchengetedza.
Iyi mitemo inosimbisa basa rakakosha rePRVs mumagetsi ekudzvinyirira moto. Nekusangana nezviyero izvi, maPRV haangokwidziridzike chete asiwo anovimbisa kutevedza zvinodiwa neindasitiri, zvichiita kuti ive dombo rekona rekudzivirira moto kwemazuva ano.
Mabhenefiti Akakosha eKudzvinyirira Kudzora Mavharuvhu
Kuvandudzwa Kwehupenyu Hwekureba kweMoto Suppression Systems
Pressure Regulating Mavhavhazvakanyanya kuwedzera hupenyu hwemasisitimu ekudzivirira moto nekuchengetedza zvikamu zvakakosha kubva mukukuvadzwa kunokonzerwa nekushanduka kwemvura. Nokufamba kwenguva, dzvinyiriro yakanyanyisa inogona kunetesa mapaipi, mavharuvhu, uye zvokusasa mvura, zvichiita kuti zvigadziriswe zvinodhura kana kuti kutsiviwa.
