Gost Hom Hluav Taws Xob Hydrants

Gost- hom hluav taws kub hydrants (ua raws li Lavxias teb sab GOST cov qauv) yog cov khoom siv hluav taws xob hauv nroog. Lawv txuas mus rau cov hoses, muab siab - dej siab rau cov neeg tua hluav taws tua hluav taws, txwv tsis pub hluav taws kub hnyiab, thiab tiv thaiv lub neej thiab cov khoom raws li qhov tseem ceeb ntawm cov hluav taws kub ceev.

Ca-Fire Protection Co., Ltd yog ib qho ntawm cov tuam ntxhab thiab cov muag khoom ntawm gost type fire hydrants hauv Suav teb. Txais tos rau kev lag luam wholesale kev cai ua khoom siv hluav taws xob ntawm tus nqi sib tw los ntawm peb lub hoobkas. Tiv tauj peb rau cov khoom pheej yig dua.

Gost hom hluav taws kub hydrants-Cov qauv GOST tshwj xeeb tswj cov dej tua hluav taws li cas?

Gost hom hluav taws kub hydrants--GOST hom

GOST- hom hluav taws tua hluav taws yog tswj hwm los ntawm Russia lub teb chaws GOST cov qauv, nrog cov kev cai tseem ceeb suav nrog:

GOST R 50574-93: Txhais cov kev qhia tshwj xeeb rau saum toj no - cov hluav taws kub hauv av, npog cov qauv tsim, kev ua haujlwm siab (feem ntau 1.6 MPa), corrosion- cov khoom siv tiv thaiv (tsim rau Russia cov huab cua txias), thiab cov txheej txheem kuaj kev ua haujlwm.

GOST 12.4.009-83: Teeb cov qauv kev nyab xeeb rau cov khoom siv hluav taws xob, cov khoom tiv thaiv, thiab kev tiv thaiv kev ua haujlwm kom tsis txhob siv tsis raug lossis raug mob.

GOST 28235-89: Standardizes hydrant qhov hluav taws xob interfaces, kom ntseeg tau tias compatibility nrog GOST -raws li hluav taws hoses thiab fittings.

Cov qauv no ua kom ntseeg tau tias GOST hydrants ua tau raws li Lavxias txoj cai kev nyab xeeb hluav taws, xa cov kev ua tau zoo hauv qhov chaw txias, hnyav.

Gost type fire hydrants---Yuav ua li cas kom muaj kev nyab xeeb ntawm GOST-hom hluav taws tua hluav taws?

Kev khiav hauj lwm GOST- hom hluav taws kub hydrant kom nyab xeeb (raws li GOST R 50574-93) yuav tsum muaj cov neeg ua haujlwm cob qhia: Ua ntej, tshem thaj tsam ntawm qhov thaiv thiab tshem nws cov Frost - tiv thaiv lub hau, tshuaj xyuas qhov hluav taws xob puas tsuaj. Siv GOST- cov ciaj ntswj tshwj xeeb kom maj mam qhib qhov tswj lub valve-tsis txhob cia li qhib tag nrho los tiv thaiv dej rauj (qhov kev pheej hmoo tseem ceeb hauv Russia cov huab cua txias).

Tom ntej no, tuav lub GOST- ua raws li qhov hluav taws kub hose rau lub qhov hluav taws xob rau lub foob kaw ntom nti. Qhib lub valve kom ncav cuag nws tus qauv 1.6 MPa ua haujlwm siab, txheeb xyuas qhov ntws tsis tu ncua.

Tom qab- siv, kaw lub valve maj mam, ntws cov dej seem (tseem ceeb kom tsis txhob khov), thiab rov qab muab lub hau rov qab. Kev ua haujlwm tsis raug tso cai ua rau muaj kev puas tsuaj rau cov khoom siv lossis kev raug mob, yog li tsuas yog cov neeg ua haujlwm tau txais kev cob qhia yuav tsum tuav cov dej ntws.

Ua ntej-Lub caij ntuj no lim dej & tshem tawm cov dej seem

Qhov tseem ceeb rau GOST qhov hluav taws kub hydrants (ib GOST R 50574-93), cov kauj ruam no yuav tsum muaj cov dej ntws tag nrho tom qab txhua qhov kev siv-Lub caij ntuj no txias hauv Lavxias teb sab yuav ua rau khov, uas tuaj yeem tawg lub cev hlau. Tshawb xyuas lub hydrant lub built-in kua valve kom paub meej tias tsis muaj kev cuam tshuam; tshem tawm cov khib nyiab uas tuaj yeem thaiv kev khiav tawm dej. Rau lub sijhawm tsis ua haujlwm ntev, paub meej tias tsis muaj dej nyob ruaj khov, vim tias dej khov tuaj yeem ua rau cov khoom siv sab hauv puas.

Frost-Resistant Component Check

Lub hom phiaj cov khoom uas muaj qhov kub thiab txias: tshuaj xyuas cov roj hmab ntsaws ruaj ruaj (yuav ua rau brittleness thaum txias) thiab hloov cov hnub nyoog raws li GOST 12.4.009-83. Txheeb xyuas qhov tseeb ntawm Frost -cov pov thawj tiv thaiv lub kaus mom- xyuas kom nws kaw nruj nreem los thaiv cov daus / dej khov nkag. Tshawb xyuas cov tshuaj tiv thaiv -cov tshuaj tiv thaiv corrosive (epoxy lossis xim txias-resistant) rau cov chips; kov cov chaw puas tsuaj los tiv thaiv xeb, uas ua rau cov dej khov, ntub dej.

Lub hli Lub caij ntuj no muaj nuj nqi kuaj

Ua luv luv, tswj cov kev ntsuam xyuas (ib hlis) kom tsis txhob raug dej ntev: qhib lub valve ib nrab kom paub meej tias ntws tsis tu ncua (raws li GOST's 1.6 MPa ua haujlwm siab), ces tam sim ntawd ntws tag nrho cov dej. Qhov no validates operability yam tsis tau tso cov residual kua kom khov. Cov ntaub ntawv siab thiab dej ua haujlwm; hais txog cov teeb meem me me (xws li, ntws qeeb) kom tsis txhob muaj xwm txheej ceev hauv qhov kub thiab txias.
