Ukugcinwa kwevalvu yokulawula kunye nokugcinwa

Ivalve yokulawulaukugcinwa nokugcinwa

Ivalve yokulawula i-valve sisixhobo esibalulekileyo kwinkqubo yokuveliswa kwemveliso, isetyenziswa ngokubanzi kwishishini lemichiza, i-petroleum, amandla ombane, imigodi kunye namanye amashishini ahlukeneyo, asetyenziselwa ukulawula ukuhamba, uxinzelelo kunye nobushushu be-medium kumbhobho. Sisixhobo esinzima somatshini esifuna ukugcinwa kunye nokugcinwa rhoqo.

Okokuqala, ukuhlolwa kwansuku zonke

Ukuhlolwa kwevalvu rhoqo kuyimfuneko kakhulu. Ikakhulu ibandakanya ukuba ngaba ukusebenza kwevalve kuqhelekile, nokuba isiphelo sivuza ioli, nokuba umzimba wevalve uvuza, njl., kwaye usombulule ingxaki ngexesha lokuqinisekisa ukusebenza ngokukhuselekileyo kwevalve ixesha elide.

Okwesibini, ukucoca kunye nokuthambisa

Ukuvulwa kunye nokuvalwa kwevalve kulawulwa yipiston, ibhola, inkunzi yegusha, njl. Njengoko ixesha lihamba, ezi nxalenye ziya kubandezeleka ngenxa yokugqoka kunye nokungcola ngenxa yokuxhatshazwa. Ngoko ke, kuyimfuneko ukucoca kunye nokuthambisa ezi ndawo rhoqo. Ioli yokuthambisa kufuneka ibe yioyile yomatshini, kwaye iyafuneka ukuba ihlangabezane neemfuno zomenzi wevalvu.

Okwesithathu, ukugcinwa kwevalvu

Ukugcinwa kwe-valve kufuneka kujoliswe kuyo, ngokuhambelana nokusetyenziswa kwe-valve kunye nendawo yokusebenza ihluke, indlela yokugcina ihluke. Ngokubanzi, ibandakanya le miba ilandelayo:

1. Iindawo ezichithiweyo kufuneka zitshintshwe ngexesha, ukuqhekeka, umonakalo kunye nezinye iimpawu kufuneka zitshintshwe ngexesha.

2. Ezinye iivalve ziya kugqwala kwinkqubo yokusetyenziswa kwexesha elide, ngeli xesha, unyango lwepeyinti kufuneka luqhutywe ukukhusela isantya sokugqwala.

3. Nika ingqalelo ekukhuselweni kweengxenye zetsimbi xa ufaka kunye nokuqhaqha iivalve. Xa utshintsha i-gasket entsha, hlambulula ubuso kwaye ukhusele ukunyameka kwe-gasket.

4. Kwiivalve ezixhotywe ngeenjini, ukugcinwa rhoqo kweengxenye zombane kufuneka kwenziwe. Khangela ukuba intambo yoqhagamshelwano ye-relay yombane ikwimeko efanelekileyo kwaye intambo ikhuselwe ngokufanelekileyo.

Okwesine, ukugcinwa kwevalvu yokulawula i-hydraulic

1. Rhoqo ujonge umgangatho kunye nomgangatho we-oyile wepompo yombane, utshintshe ioli ngexesha elifanelekileyo, ucoce into yokucoca ipompo, ukulungiswa kunye nokutywinwa, ukuqinisekisa ukusebenza okuqhelekileyo kwemoto kunye nepompo.

2. Khangela rhoqo ukuba ibhokisi yokulawula umbane kunye ne-wiring yayo iyinto eqhelekileyo, hlambulula uthuli kwibhokisi yokulawula, kwaye ugcine ibhokisi yokulawula yomile.

3. Vavanya ivalve yokulawula ihydraulic rhoqo ukuqinisekisa ukusebenza kwayo okuqhelekileyo. Uvavanyo lubandakanya ukulungelelanisa uxinzelelo, ukuzinza kunye nomthamo.

Kumsebenzi oqhelekileyo wolondolozo nowokugcina, kufuneka kwakhona sinikele ingqalelo kwezi ngongoma zilandelayo:

1. Kwinkqubo yokuthutha kunye nokufakwa, i-valve kufuneka ithintelwe kwimpembelelo, ukumiswa, uxinzelelo olugqithiseleyo kunye nezinye izinto ezichaphazelayo.

2. I-valve kufuneka igcinwe kwindawo enothuli oluncinci, i-gas corrosive kunye ne-60% ye-humidity ehambelanayo.

Ukugcinwa kwevalve ngokuchanekileyo kunye nokugcinwa, kunokwandisa ngokufanelekileyo ubomi be-valve, ukuqinisekisa ukhuseleko lwemveliso yefektri. Ngoko ke, amashishini kufuneka aqinise ukugcinwa kunye nokugcinwa kwee-valve, uphando lwangexesha lweengozi ezifihliweyo, ukuqinisekisa ukusebenza okuzinzile kwezixhobo.
