1.Ongeramo amavuta yo gufunga

Ku mavali adakoresha amavuta yo gufunga, tekereza kongeramo amavuta yo gufunga kugira ngo wongere imikorere yo gufunga inkingi ya vali.

2. Ongeraho icyunguruzo

Kugira ngo hongerwe uburyo bwo gufunga ipaki ku gice cy’imashini, uburyo bwo kongeramo ipaki bushobora gukoreshwa. Ubusanzwe, hakoreshwa imashini zivanze zifite ibyiciro bibiri cyangwa ibyiciro byinshi. Kongera umubare gusa, nko kongera umubare uva ku bice 3 ukagera kuri 5, ntabwo bizagira ingaruka zigaragara.

3. Simbuza icyuma gipima girafu

Ipaki ya PTFE ikoreshwa cyane ifite ubushyuhe buri hagati ya -20 na +200°C. Iyo ubushyuhe buhindutse cyane hagati y’aho hejuru n’aho hasi, imikorere yayo yo gufunga izagabanuka cyane, izasaza vuba kandi igihe cyayo kizaba gito.

Utwuma duto twa grafiti dutsinda izo mbogamizi kandi tumarana igihe kirekire. Kubwibyo, zimwe mu nganda zahinduye uburyo bwose bwo gupakira PTFE zijya mu gupakira graphite, ndetse n'utumashini dushya twaguzwe twakoreshejwe nyuma yo gusimbuza PTFE packing n'utwuma duto twa grafiti. Ariko, hysteresis yo gukoresha graphite filler ni nini, kandi rimwe na rimwe habanza kubaho gukurura, bityo rero ibi bigomba kwitabwaho.

4. Hindura icyerekezo cy'amazi hanyuma ushyire P2 ku mpera y'umugongo wa valve.

Iyo △P ari nini na P1 ari nini, gufunga P1 biragoye cyane kuruta gufunga P2. Kubwibyo, icyerekezo cy'amazi gishobora guhinduka kuva kuri P1 ku mpera y'umugongo wa valve ukajya kuri P2 ku mpera y'umugongo wa valve, ibi bikaba ingirakamaro cyane ku mavali afite umuvuduko mwinshi n'itandukaniro rikomeye ry'umuvuduko. Urugero, mavali zo mu bwoko bwa bellows zigomba gutekereza ku gufunga P2.

5. Koresha uburyo bwo gufunga gasket ya lens

Ku bijyanye no gufunga ibifuniko byo hejuru n'ibyo hasi, gufunga icyicaro cya valve n'imibiri ya valve yo hejuru n'iyo hasi. Niba ari agapfundikizo gatambitse, mu gihe cy'ubushyuhe bwinshi n'umuvuduko mwinshi, imikorere yo gufunga iba mibi, bigatuma habaho gusohoka. Ushobora gukoresha agapfundikizo ka gasket ya lens, gashobora kugera ku musaruro ushimishije.

6. Simbuza gasket yo gufunga

Kugeza ubu, gasket nyinshi zo gufunga ziracyakoresha imbaho ​​za asbestos. Iyo ubushyuhe buri hejuru, imikorere yo gufunga iba mibi kandi igihe cyo kuyikora ni gito, bigatuma amazi ava. Muri iki gihe, ushobora gukoresha gasket zo mu bwoko bwa spiral wound, impeta za "O", n'ibindi, inganda nyinshi zimaze gukoresha ubu.

7. Fata amaboliti neza kandi ufunge ukoresheje gaskets ntoya

Mu miterere ya valve igenzura ifite agapfundikizo ka "O", iyo hakoreshejwe gasket nini zifite ububobere bunini (nk'amabati yo kuzunguruka), iyo gukanda nta bubobere kandi imbaraga zitangana, agapfundikizo kazangirika byoroshye, karahengamye kandi kagahinduka. Bigira ingaruka zikomeye ku mikorere yo gufunga.

Kubwibyo, mu gihe cyo gusana no guteranya ubwoko bw'iyi valve, imigozi yo gukanda igomba gukomera neza (menya ko idashobora gukomera icyarimwe). Byaba byiza iyo gasket nini ishobora guhindurwamo gasket nto, ishobora kugabanya uburyo bwo kuzenguruka no gutuma ifunga neza.

8. Ongera ubugari bw'ubuso bwo gufunga

Umutima wa valve ugororotse (nk'agace ka valve ka valve ifite imyanya ibiri na valve yo mu ntoki) nta gice cy'ubuyobozi n'ubuyobozi gifite imiterere igoramye mu ntebe ya valve. Iyo valve ikora, umutima wa valve ufatwa n'imbaraga zo ku ruhande kandi usohoka mu cyerekezo cy'inzira. Uko igice cy'umubiri wa valve kiba kinini, ni ko iki kibazo cyo ku ruhande rumwe kirushaho kuba gikomeye. Byongeye kandi, guhinduka, kudahuza, cyangwa gucika gato k'ubuso bw'inkingi ya valve (muri rusange gufunga kuri dogere 30 ku bugenzuzi) bizatuma igice cy'umubiri wa valve kizingirwa iyo kiri hafi gufunga. Impande ya chamfered ishyirwa ku buso bw'inkingi ya valve, bigatuma igice cy'umubiri wa valve kizinduka iyo gifunze, cyangwa kitafunga na gato, bigatuma valve isohoka cyane.

Uburyo bworoshye kandi bunoze ni ukongera ingano y'ubuso bwo gufunga igice cy'imbere cya valve, ku buryo umurambararo muto w'inyuma y'igice cy'imbere cya valve uba muto kuri mm 1 kugeza kuri 5 ugereranije n'umurambararo w'intebe ya valve, kandi ukagira ubuyobozi buhagije bwo kwemeza ko igice cy'imbere cya valve kiyoborwa mu ntebe ya valve kandi kigakomeza gukorana neza n'ubuso bwo gufunga.
