Noma yikuphi ukusesha kwe-inthanethi okusheshayo kwe-valve kuzoveza imiphumela eminingi ehlukene: manual noma othomathikhi, ithusi noma insimbi engagqwali, i-flanged noma i-NPT, ucezu olulodwa, izingcezu ezimbili noma ezintathu, njalonjalo. Njengoba kunezinhlobo eziningi ezahlukene zama-valve ongakhetha kuzo, ungaqiniseka kanjani ukuthi uthenga uhlobo olulungile? Nakuba isicelo sakho sizokusiza ekukhetheni ama-valve afanele, kubalulekile ukuba nokuqonda okuyisisekelo kwezinhlobo ezahlukene zamavalvu ahlinzekwayo.

I-valve yocezu olulodwa lwebhola inomzimba wabalingisi oqinile owehlisa ubungozi bokuvuza. Ashibhile futhi ngokuvamile awalungiswa.

Ama-valve aneziqephu ezimbili zebhola amanye asetshenziswa kakhuluama-valve ebhola. Njengoba igama liphakamisa, i-valve yebhola eneziqephu ezimbili iqukethe izingcezu ezimbili, ucezu olunocezu oluxhunywe ekugcineni kanye nomzimba we-valve. Isiqephu sesibili silingana phezu kwesiqephu sokuqala, sibambe i-trim endaweni futhi sihlanganisa uxhumano lwesiphetho sesibili. Uma esefakiwe, la mavalvu ngokuvamile awakwazi ukulungiswa ngaphandle uma ekhishiwe emsebenzini.

Futhi, njengoba igama liphakamisa, i-valve yebhola eneziqephu ezintathu iqukethe izingxenye ezintathu: ama-caps amabili kanye nomzimba. Amakepisi okugcina ngokuvamile acutshungulwa noma ashiselwe epayipini, futhi ingxenye yomzimba ingasuswa kalula ukuze ihlanzwe noma ilungiswe ngaphandle kokukhipha isiphetho. Lokhu kungaba inketho ebaluleke kakhulu njengoba kuvimbela ulayini wokukhiqiza ukuthi uvalwe lapho kudingekile ukulungiswa.

Ngokuqhathanisa izici zevalvu ngayinye nezidingo zakho zokufaka isicelo, uzokwazi ukwenza isinqumo esinolwazi esivumelana kangcono nezidingo zakho. Vakashela iwebhusayithi yethu ye-valve ukuze ufunde ngomugqa wethu womkhiqizo we-valve yebhola noma uqale ukulungisa namuhla.

Ukuchayeka kwe-UV
EmhlopheIpayipi le-PVC,uhlobo olusetshenziselwa amapayipi amanzi, luyawohloka lapho luvezwe ukukhanya kwe-UV, njengokuvela elangeni. Lokhu kwenza okokusebenza kungafaneleki ezinhlelweni zokusebenza zangaphandle lapho kungeke kuhlanganiswe khona, njengezigxobo zefulegi nezinhlelo zokufulela. Ngokuhamba kwesikhathi, ukuchayeka kwe-UV kunciphisa ukuguquguquka kwezinto ngokucekelwa phansi kwe-polymer, okungaholela ekuqhekekeni, ekuqhekekeni, nasekuhlukaniseni.

izinga lokushisa eliphansi
Njengoba izinga lokushisa lehla, i-PVC iba brittle kakhulu. Uma ibhekene namazinga okushisa abandayo isikhathi eside, iba brittle futhi iqhekeke kalula. I-PVC ayizilungele izinhlelo zokusebenza ezingaphansi kwamazinga okushisa aqandayo angashintshi, futhi amanzi akufanele neze abe yiqhwa ngaphakathiAmapayipi e-PVCnjengoba kungabangela ukuqhekeka nokuqhuma.

iminyaka yobudala
Wonke ama-polymers noma amapulasitiki ehla ngezinga elithile ngokuhamba kwesikhathi. Kungumkhiqizo wokwakheka kwawo kwamakhemikhali. Ngokuhamba kwesikhathi, i-PVC idonsa izinto ezibizwa ngokuthi ama-plasticizers. Ama-Plasticizers ayengezwa ku-PVC ngesikhathi sokukhiqizwa ukuze kwandiswe ukuguquguquka kwawo. Lapho befuduka ngaphandle kwamapayipi e-PVC, amapayipi awagcini nje ngokuguquguquka kancane ngenxa yokuntuleka kwawo, kodwa futhi ashiywe eneziphambeko ngenxa yokuntuleka kwama-molecule e-plasticizer, angadala imifantu noma imifantu emapayipini.

ukuchayeka kwamakhemikhali
Amapayipi e-PVC angaba brittle ngenxa yokuchayeka kwamakhemikhali. Njenge-polymer, amakhemikhali angaba nomthelela omubi kakhulu ekwenziweni kwe-PVC, axege izibopho phakathi kwama-molecule epulasitiki futhi asheshise ukufuduka kwama-plasticizers aphume emapayipini. Amapayipi okukhipha amanzi e-PVC angaba brittle uma evezwe amanani amakhulu amakhemikhali, njengalawo atholakala kuma-drain plug removers.
