Noma yikuphi ukusesha okusheshayo kwe-inthanethi kwe-valve kuzoveza imiphumela eminingi ehlukene: ngesandla noma ngokuzenzakalelayo, ithusi noma insimbi engagqwali, i-flanged noma i-NPT, ingxenye eyodwa, izingcezu ezimbili noma ezintathu, njalo njalo. Njengoba kunezinhlobo eziningi kangaka zama-valve ongakhetha kuzo, ungaqiniseka kanjani ukuthi uthenga uhlobo olufanele? Nakuba isicelo sakho sizokusiza ekukhetheni ama-valve ngendlela efanele, kubalulekile ukuba nokuqonda okuyisisekelo kwezinhlobo ezahlukene zama-valve anikezwayo.

Ivalvu yebhola enengxenye eyodwa inomzimba oqinile oncishisiwe onciphisa ingozi yokuvuza. Ishibhile futhi ngokuvamile ayilungiswa.

Amavalvu ebhola anezingcezu ezimbili angenye yamavalvu asetshenziswa kakhuluamavalvu ebholaNjengoba igama lisho, ivalvu yebhola enezicucu ezimbili yakhiwe yizicucu ezimbili, ucezu olunengxenye exhunywe kolunye uhlangothi kanye nomzimba wevalvu. Ucezu lwesibili lungena phezu kwengxenye yokuqala, lubamba uthango endaweni yalo futhi luhlanganisa uxhumano lwengxenye yesibili. Uma selufakiwe, lawa mavalvu ngokuvamile awakwazi ukulungiswa ngaphandle kokuthi asuswe ekusebenzeni.

Futhi, njengoba igama lisho, ivalvu yebhola enezingcezu ezintathu inezingxenye ezintathu: izingcezu ezimbili zokugcina kanye nomzimba. Izingcezu zokugcina zivame ukufakwa ngentambo noma zixhunywe epayipini, futhi ingxenye yomzimba ingasuswa kalula ukuze ihlanzwe noma ilungiswe ngaphandle kokususa isingcezu sokugcina. Lokhu kungaba inketho ewusizo kakhulu njengoba kuvimbela umugqa wokukhiqiza ukuthi uvalwe lapho kudingeka ukulungiswa.

Ngokuqhathanisa izici zevalvu ngayinye nezidingo zakho zohlelo lokusebenza, uzokwazi ukwenza isinqumo esinolwazi esifanelana kahle nezidingo zakho. Vakashela iwebhusayithi yethu yevalvu ukuze ufunde ngomugqa wethu womkhiqizo wevalvu yebhola noma ukuqala ukumisa namuhla.

Ukuvezwa kwe-UV
OkumhlopheIpayipi le-PVC,uhlobo olusetshenziselwa ukufaka amapayipi, luyaphuka uma luvezwa ekukhanyeni kwe-UV, njengoba nje kuvela elangeni. Lokhu kwenza izinto zingafaneleki ukusetshenziswa ngaphandle lapho zingeke zimbozwe khona, njengezigxobo zefulegi kanye nezicelo zokuphahla. Ngokuhamba kwesikhathi, ukuvezwa kwe-UV kunciphisa ukuguquguquka kwezinto ngokonakala kwe-polymer, okungaholela ekuqhekekeni, ekuqhekekeni, nasekuqhekekeni.

izinga lokushisa eliphansi
Njengoba izinga lokushisa lehla, i-PVC iba buthakathaka kakhulu. Uma ibhekene namazinga okushisa abandayo isikhathi eside, iba buthakathaka futhi iqhekeke kalula. I-PVC ayifanele ukusetshenziswa ngaphansi kwamazinga okushisa abandayo ahlala njalo, futhi amanzi akufanele aqine ngaphakathi.Amapayipi e-PVCnjengoba kungabangela ukuqhekeka nokuqhuma.

ubudala
Zonke i-polymer noma ipulasitiki ziyawohloka ngezinga elithile ngokuhamba kwesikhathi. Kungumkhiqizo wokwakheka kwamakhemikhali azo. Ngokuhamba kwesikhathi, i-PVC imunca izinto ezibizwa ngokuthi ama-plasticizer. Ama-plasticizer ayengezwa ku-PVC ngesikhathi sokwenziwa ukuze kwandiswe ukuguquguquka kwayo. Uma ephuma emapayipini e-PVC, amapayipi awagcini nje ngokuba nokuguquguquka okuncane ngenxa yokuntuleka kwawo, kodwa futhi asala namaphutha ngenxa yokuntuleka kwama-molecule e-plasticizer, okungadala imifantu noma imifantu emapayipini.

ukuchayeka kumakhemikhali
Amapayipi e-PVC angaba buthakathaka ngenxa yokuchayeka kumakhemikhali. Njenge-polymer, amakhemikhali angaba nomthelela omubi kakhulu ekwakhekeni kwe-PVC, akhulule izibopho phakathi kwama-molecule epulasitiki futhi asheshise ukufuduka kwama-plasticizers aphuma emapayipini. Amapayipi okukhipha amanzi e-PVC angaba buthakathaka uma evezwa kumakhemikhali amaningi, njengalawo atholakala kuma-remover e-drain plug aketshezi.
