Koj puas tau xav tias yog vim li cas chav dej hauv tsev so tsis tshua muaj dej ntws los ntawm tes- tuav da dej? Qhov zais cia feem ntau nyob hauv kev sib txuas tshuab. Cov neeg siv khoom txheem-qib cov raj feem ntau yog nyob ntawm ib qho chaw compression, uas tuaj yeem yooj yim tsis muaj zog thaum lub sijhawm rub tawm thiab qhov kub thiab txias hloov pauv txhua hnub. Txawm li cas los xij, cov neeg ua haujlwm kav dej rau siab - cov haujlwm ua lag luam muaj txiaj ntsig tam sim no nruj me ntsis yuav tsum tau ua kom nrawm nrawm kom tsis txhob raug nqi dej ntau. Aob chav crimped da dej hosedaws qhov tsis zoo no los ntawm kev siv ob qhov sib txawv, qhov tseeb -engineered crimps ntawm lub ferrule. Koj tuaj yeem pom qhov pom qhov no los ntawm kev nrhiav ob lub ntsej muag pom tseeb nyob ze ntawm cov hlau txuas. Qhov no dual -taw tes thev naus laus zis muab cov cuab yeej ua haujlwm loj heev uas tiv thaiv cov raj sab hauv kom tsis txhob plam tawm ntawm lub qhov rooj sab nraud. Cov ntaub ntawv kev lag luam qhia tau hais tias kev hloov mus rau qhov kev tsim kho tshiab no ua rau txo qis kev hu xov tooj rau hauv hnyav - chaw tsheb khiav zoo li gyms thiab tsev kho mob, qhov twg niaj hnub hnav thiab tsim kua muag sai sai ua rau tus qauv ib zaug - crimp fittings.
Tshaj li qhov kev sib txuas ntawm cov tshuab, cov khoom siv raw hauv cov khoom siv tam sim no pom kev hloov kho tshiab kom tau raws li cov cai nruj dua kev noj qab haus huv thiab kev nyab xeeb. Cov neeg tsim khoom tau txav deb ntawm PVC pheej yig thiab siv cov khoom noj uas muaj ntawv pov thawj -qib EPDM rau cov raj sab hauv. Cov khoom siv no ua haujlwm kub hloov pauv ntawm -10℃mus rau 90℃yam tsis muaj degrading lossis tso tshuaj lom rau hauv cov dej ntws. Txhawm rau tiv thaiv cov tub ntxhais no, txheej txheej txheej ntawm 304 stainless hlau braid yog siv, muab cov xeb zoo heev. Ua ntej ntaus lub lag luam, txhim khu kev qhaob chav crimped da dej hoseyuav tsum dhau qhov kev kuaj xyuas zoo. Nws yuav tsum tau tiv thaiv lub cev rub tawm - tawm lub zog tsawg kawg yog 500 Newtons thiab tuav 1.5 npaug ntawm nws qhov kev ua haujlwm tsis tu ncua rau peb caug feeb yam tsis muaj tawg. Rau kev teeb tsa, cov neeg siv yooj yim kho cov G1/2 British yeeb nkab xov nrog lub qhov hluav taws xob ntawm phab ntsa thiab tes- nruj; qhov kev txhim kho cov qauv kev ncaj ncees ua kom cov kev teeb tsa tseem ruaj ntseg txawm tias nyob rau hauv lub siab nrawm nrawm.
