Uhlalutyo loMgaqo wokuSebenza kunye noLwakhiwo oluSiseko lwe (iValve yeGlobe)

(Ivalve yeglowubhu), ekwaziwa ngokuba sisivalo sokuvala, sisivalo esiqhele ukusetyenziswa. Umgaqo wayo wokusebenza ikakhulu usebenzisa ukuphakanyiswa kwesiqu sevalve ukuqhuba intloko yevalve, ngaloo ndlela itshintsha umgama phakathi kwediski yevalve kunye nesihlalo sevalve, kunye nokufezekisa injongo yokulawula ukuhamba kolwelo.

Ulwakhiwo olusisiseko lwevalve yeglowubhu lubandakanya ezi ndawo zilandelayo:

1. Umzimba wevalvu: Ngumzimba ongundoqo wevalve yeglowubhu, osetyenziselwa ukuqhagamshela imibhobho, kwaye uneendlela zokudlula ulwelo.

2. Isigqubuthelo sevalvu: sibekwe kwindawo ephezulu yevalve yomzimba, edla ngokudityaniswa nomzimba wevalve, esetyenziselwa ukuxhasa isiqu sevalve kunye nokubonelela ngokutywinwa.

3. Isiqu sevalve: Yinxalenye yokusebenza yevalve yeglowubhu, elawula ukuvulwa nokuvalwa kwevalve ngokunyuka okanye ukuwa.

4. Idiskhi: Iqhagamshelwe kwisiqu sevalve, inxibelelana okanye yahlule kwisihlalo sevalve ngokusehla inyuka, ngaloo ndlela ifezekisa ukutywinwa okanye ukuvula umjelo.

5. Isihlalo sevalve: Ifakwe ngaphakathi kumzimba wevalve, yinxalenye ephambili esebenzisana nediski yevalve ukufezekisa ukutywinwa.

6. Umphezulu wokutywina: Umphezulu osetyenziselwa ukutywinwa kwidiski yevalve kunye nesihlalo, ngokuqhelekileyo ufuna ukuchaneka kwe-machining ukuqinisekisa isiphumo esihle sokutywinwa.

7. I-Handwheel: Ifakwe phezulu kwi-valve stem, esetyenziselwa ukusebenza ngokuvula kunye nokuvalwa kwevalve.

Izibonelelo zevalve yeglowubhu ziquka:

1. Ukusebenza kakuhle kokutywinwa: Ngenxa yokungqubana okuphantsi phakathi kwediski yevalve kunye nevalve yomzimba wokutywina umphezulu, ayinyangeki.

2. Ukwenziwa lula kunye nokugcinwa lula: Ngokuqhelekileyo, kukho enye indawo yokutywina kumzimba we-valve kunye nediski, enenkqubo yokuvelisa kakuhle kwaye kulula ukuyilungisa.

3. Ubude obuncinci bokuvula: Xa kuthelekiswa nezinye iintlobo zeevalve, (i-valve yeglobhu) inobude obuncinci bokuvula.

Nangona kunjalo, kukwakho ezinye iingxaki kwi (iivalvu zeglowubhu):

1. Ukuchasana kwamanzi aphezulu: Ngenxa yobume bomjelo wangaphakathi, ukunyanzeliswa kwamanzi kwi-valve yokuvala kuphezulu.

2. Ayifanelekanga kwimidiya ene-viscosity ephezulu okanye i-crystallization elula: Kwimveliso yangempela, isetyenziselwa ukulawula imibhobho efana namanzi, i-steam, kunye nomoya oxinyiweyo, kodwa ayifanelekanga kwizinto ezine-viscosity ephezulu okanye i-crystallization elula.

3. Ubude bolwakhiwo olude: Xa kuthelekiswa nezinye iintlobo zeevalvu, (ivalve yeglowubhu) inobude bolwakhiwo olude.

Isishwankathelo, xa ukhetha kwaye usebenzisa (iivalve zeglowubhu), kuyimfuneko ukugqiba ukuba ngaba zikulungele ukusetyenziswa ngokusekelwe kwiimeko zokusebenza kunye neempawu eziphakathi, kwaye ubeke ingqalelo kulwalathiso lwabo lofakelo kunye nokugcinwa ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwesivalo. kwaye yandise ubomi bayo benkonzo.
