Ivalve yeglowubhu evaliweyoyivalve yeglowubhu enemivumbo yentsimbi elastiki yokusebenza okuphezulu kunye nobomi obude bokudinwa beteleskopu. Ukusebenzisa uyilo lwe-bellows seal, ukuphelisa ngokupheleleyo i-valve ye-stem yokupakisha itywina ukuguga ngokukhawuleza ukusilela, kungekuphela nje ukuphucula ukusetyenziswa kwamandla, ukwandisa ukhuseleko lwezixhobo zemveliso, ukunciphisa iindleko zokugcinwa kunye nokugcinwa rhoqo, kodwa nokubonelela ngendawo yokusebenza ecocekileyo nekhuselekileyo.

Iimpawu zesakhiwo se

1. Uyilo olutywiniweyo oluphindwe kabini (iimvumba + ukupakisha) Ukuba imivumbo iyasilela, ukupakishwa kwesikhondo kuya kuphetshwa.

2. Isakhiwo esinengqiqo, ukutywinwa okuthembekileyo, ukusebenza kakuhle, ukubonakala okuhle.

3. Akukho kulahleka kwamanzi, ukunciphisa ukulahleka kwamandla, ukuphucula ukhuseleko lwezixhobo zezityalo.

4. Umphezulu wokutywina we-surfacing Co esekelwe kwi-alloy eqinile, ukumelana nokunxiba, ukuxhathisa ukubola, ukuxhathisa i-friction, ubomi obude benkonzo, ukunciphisa inani lokugcinwa, ukunciphisa iindleko zokusebenza.

5. Uyilo lwetywina lwemibhobhobhobho luqinisekisa ukuvuza kwesiqu esingu-zero kwaye akukho londolozo.

6. Ukumisa ukulungiswa kwe-valve stem kunye nonyango lwe-nitriding yomhlaba, inokumelana nokukhula okulungileyo kunye nokumelana nokukhuhla;

7. Isalathiso esicacileyo sokuphakama kwesikhondo sevalve.

 Uluhlu lwesicelo

Ivalve yeglowubhu ye-Bellows ilungele i-petroleum, ikhemikhali, amayeza, isichumisi sekhemikhali, amandla ombane kunye namanye amashishini phantsi kweemeko ezahlukeneyo zokusebenza zombhobho, osetyenziselwa ukusika okanye ukubeka phakathi kombhobho.
