Mu bihe bisanzwe, valve zo mu nganda ntizikora ibizamini by'imbaraga iyo zikoreshwa, ariko nyuma yo gusana igice cy'ingufu n'igipfundikizo cya valve cyangwa kwangirika kw'igice cy'ingufu n'igipfundikizo cya valve bigomba gukora ibizamini by'imbaraga. Ku bijyanye n'umutekano, igitutu cyo gushyiraho n'igitutu cyo kugaruka hamwe n'ibindi bizamini bigomba kubahiriza amabwiriza n'amabwiriza abigenga. Valve igomba gupimwa imbaraga n'ubukana mbere yo kuyishyiraho. Valve zo mu rwego rwo hejuru n'iziciriritse zigomba kugenzurwa. Ikizamini cy'igitutu cya valve gikunze gukoreshwa ni amazi, amavuta, umwuka, umwuka, azote, n'ibindi. Ubwoko bwose bwa valve zo mu nganda harimo na valve zo mu mwuka ni ubu bukurikira:

1.Valve y'umupirauburyo bwo gupima igitutu

Igeragezwa ry'imbaraga za valve y'umupira w'umwuka rigomba gukorwa mu gihe umupira ufunguye igice cy'umupira.

(1)Umupira urerembaikizamini cyo gufunga neza kwa valve: valve ifunguye igice, impera imwe yinjizwa mu cyuma gipima, indi impera irafunze; Hindura umupira inshuro nyinshi, fungura impera ifunze iyo valve ifunze, kandi urebe neza imikorere yo gufunga kw'igipfunyika na gasket, kandi nta gusohoka bigomba kubaho. Hanyuma shyiramo cyuma gipima uhereye ku rundi ruhande hanyuma usubiremo ikizamini cyavuzwe haruguru.

(2)Umupira uhorahoIkizamini cyo gufunga umupira: mbere y'ikizamini, umupira uzungurutswa inshuro nyinshi nta mutwaro, kandi valve y'umupira idahinduka iba ifunze, kandi icyuma gipima gikurwa ku mpera imwe kugera ku giciro cyagenwe; Igipimo cy'umuvuduko gikoreshwa mu kugenzura imikorere yo gufunga impera y'injira. Ubuziranenge bw'igipimo cy'umuvuduko ni 0.5 ~ 1, kandi intera yo gupima ni inshuro 1.5 z'umuvuduko w'ikizamini. Mu gihe cyagenwe, nta kintu cyo guhagarika umuvuduko cyemewe; Hanyuma shyiramo icyuma gipima uvuye ku yindi mpera hanyuma usubiremo ikizamini cyavuzwe haruguru. Hanyuma, valve iba ifunguye igice, impera zombi zirafunze, umwobo w'imbere wuzuramo ibyuma, kandi gupakira na gasket bigenzurwa munsi y'umuvuduko w'ikizamini nta gusohoka.

(3)Valve y'umupira w'impande eshatu sbigomba gupimwa kugira ngo harebwe niba bifatanye neza mu myanya itandukanye.

2.Valve yo kugenzurauburyo bwo gupima igitutu

Uko ikizamini cya valve gihagaze: ubwoko bwa lift check valve axis iri mu mwanya utambitse kandi uhagaze; axis y'umuyoboro wa valve check axis n'umurongo wa disiki birangana n'umurongo utambitse.

Mu gihe cyo gupima imbaraga, igikoresho cyo gupima gishyirwa ku gaciro kagenwe kavuye ku mpera y'aho yinjira, urundi ruhande rurafungwa, kandi umubiri wa valve n'igipfundikizo cya valve birasabwa nta gusohoka.

Ikizamini cyo gufunga kigomba kwinjiza uburyo bwo gupima uhereye ku mpera y'aho usohoka, kikagenzura ubuso bwo gufunga ku mpera y'aho usohoka, kandi aho upakira na gasket bigomba kuba byemewe niba nta gusohoka kwabyo.
