Igenzura mbere yo gushyiraho valve

① Suzuma witonze niba icyitegererezo cya valve n'ibipimo byayo byujuje ibisabwa mu gushushanya.

② Reba niba umugongo wa valve na disiki ya valve byoroshye mu gufungura, kandi niba byafashe cyangwa byaragoramye.

③ Reba niba valve yangiritse kandi niba imigozi ya valve ifite imigozi igororotse kandi imeze neza.

④ Reba niba isano iri hagati y'intebe ya valve n'igice cy'inyuma cy'inyuma gihamye, isano iri hagati ya disiki ya valve n'igice cy'inyuma cy'inyuma, igipfundikizo cya valve n'igice cy'inyuma cy'inyuma, hamwe n'agace k'inyuma k'inyuma n'igice cy'inyuma cy'inyuma.

⑤ Reba niba gasket ya valve, imipakire n'ibifunga (bolts) bihuye n'ibisabwa ku miterere y'igikoresho gikoreshwa.

⑥ Vali zigabanya umuvuduko zishaje cyangwa zimaze igihe kirekire zigomba gusenywa, kandi ivumbi, umucanga n'indi myanda bigomba gusukurwa n'amazi.

⑦ Kuraho umupfundikizo wo gufunga umuyoboro hanyuma urebe niba uburebure bw'umupfundikizo buhagaze. Disiki ya valve igomba gufungwa neza.

Ikizamini cy'umuvuduko wa valve

Valive zikoresha umuvuduko muke, umuvuduko uringaniye n'umuvuduko mwinshi zigomba gupimwa imbaraga no gupima ubukana bwazo. Valive z'icyuma zikozwe mu cyuma zigomba kandi gukora isesengura rya spectral ku mpande imwe imwe no gusuzuma ibikoresho.

1. Ikizamini cy'imbaraga za value

Ikizamini cy'imbaraga za valve ni ukugerageza valve iri mu mwanya ufunguye kugira ngo harebwe aho amazi aturuka ku buso bw'inyuma bwa valve. Kuri valve zifite PN ≤ 32MPa, igitutu cy'ikizamini ni inshuro 1.5 z'igitutu cyihariye, igihe cyo gusuzuma ni iminota 5, kandi nta mazi aturuka ku gishishwa n'agahu ko gupakira kugira ngo byemerwe.

2. Ikizamini cyo gufunga neza kwa value

Ikizamini gikorwa hifashishijwe valve ifunze neza kugira ngo harebwe niba hari amazi asohoka ku buso bwo kuzingira valve. Umuvuduko w'ikizamini, usibye valve z'ibinyugunyugu, valve zo kugenzura, valve zo hasi n' valve zo kugosora, muri rusange ugomba gukorwa ku gitutu cy'umuvuduko. Iyo bigaragaye ku gitutu cy'umuvuduko w'umuvuduko w'umuvuduko, ikizamini gishobora kandi gukorwa ku nshuro 1.25 z'umuvuduko w'umuvuduko w'umuvuduko w'umuvuduko w'umuvuduko, kandi ubuso bwo kuzingira bwa disc ya valve bugomba kuba bwemewe niba butavuyemo amazi.

Amategeko rusange agenga ishyirwaho rya valve

1. Aho valve ishyirwa ntabwo hagomba kubangamira imikorere, gusenya no kubungabunga ibikoresho, imiyoboro n'igice cy'imashini ubwayo, kandi ubwiza bw'aho iteranyirizwa bugomba kwitabwaho.

2. Ku byerekeye valves ziri ku miyoboro itambitse, inkingi ya valve igomba gushyirwa hejuru cyangwa igashyirwa ku nguni. Ntugashyire valve hamwe n'uruziga rw'intoki ruri hasi. Valves, inkingi za valves n'ibiziga by'intoki ku miyoboro miremire bishobora gushyirwaho bitambitse, kandi umunyururu uhagaze uri ku rwego rwo hasi ushobora gukoreshwa mu kugenzura kure aho valve ifunguka n'aho ifunga.

3. Imiterere yayo ni ndende, iratunganye kandi ni nziza; kuri valves ziri ku muyoboro uhagaze, iyo inzira ibibemerera, uruhererekane rw'amapine ni rwo rwiza cyane kugira ngo rukoreshwe ku burebure bw'igituza, muri rusange metero 1.0-1.2 uvuye ku butaka, kandi igice cy'uruhererekane kigomba gukurikiza uko umukoresha ashyiraho icyerekezo.

4. Ku byerekeye valve ziri ku miyoboro ihagaze ku ruhande rumwe, ni byiza kugira umurongo umwe wo hagati, kandi intera isobanutse hagati y'amapine y'intoki ntigomba kuba munsi ya mm 100; ku valve ziri ku miyoboro ihagaze ku rundi ruhande, zigomba guterwamo uduce duto kugira ngo zigabanye intera iri hagati y'imiyoboro.

5. Mu gihe cyo gushyiraho vali zikomeye ku mapompo y'amazi, ibyuma bihindura ubushyuhe n'ibindi bikoresho, hagomba gushyirwaho udukingirizo tw'amavali; iyo vali zikunze gukoreshwa kandi zigashyirwa ahantu harenga metero 1.8 uvuye ku buso bwo gukora, hagomba gushyirwaho urubuga rudahinduka rwo gukora.

6. Niba hari ikimenyetso cy'umwambi ku gice cy'umuyoboro, icyerekezo cy'umwambi ni icyerekezo cy'umuyoboro. Mu gushyiraho umuyoboro, menya neza ko umwambi werekana icyerekezo kimwe n'umuyoboro w'umuyoboro.

7. Mu gihe ushyiramo valves za flange, menya neza ko impande z'impande zombi zibangikanye kandi zifatanye, kandi ko gasket ebyiri zitemerewe gukoreshwa.

8. Mu gushyiraho valve ifite imigozi, kugira ngo byorohe kuyisesa, valve ifite imigozi igomba kuba ifite umugozi. Imiterere y'umugozi igomba kwita ku byoroshye kuyibungabunga. Ubusanzwe, amazi abanza gutemba muri valve hanyuma akanyura muri valve.

Uburyo bwo kwirinda gushyiramo valve

1. Ibikoresho by'umubiri wa valve ahanini ni icyuma gikozwe mu cyuma, gicika intege kandi ntikigomba gukubitwa n'ibintu biremereye.

2. Mu gutwara valve, ntuyijugunye mu buryo butunguranye; mu gihe uterura cyangwa uzamura valve, umugozi ugomba guhambirwa ku gice cy'inyuma cya valve, kandi birabujijwe kuyihambira ku ruziga rw'amaboko, ku gice cy'inyuma cya valve n'umwobo w'inyuma.

3. Valve igomba gushyirwa ahantu heza ho kuyikoresha, kuyisana no kuyigenzura, kandi birabujijwe kuyitwikira munsi y'ubutaka. Valve ziri ku miyoboro ishyinguye cyangwa mu myobo zigomba gushyirwaho amariba yo kugenzura kugira ngo yorohereze gufungura, gufunga no gukosora valve.

4. Menya neza ko insinga zimeze neza kandi zipfunyitse n'amavuta ya hemp, lisansi cyangwa kaseti ya PTFE
