Kungakanani okwaziyo ngama-valve okuhlola?

1. Iyini i-valve yokuhlola? 7. Uyini umgomo wokusebenza?

　　Hlola i-valveigama elibhaliwe, futhi ngokuvamile libizwa ngokuthi i-valve yokuhlola, i-valve yokuhlola, i-valve yokuhlola noma i-valve yokuhlola emsebenzini. Kungakhathaliseki ukuthi libizwa kanjani, ngokwencazelo engokoqobo, singahlulela cishe indima ye-valve yokuhlola ukuvimbela uketshezi ukuthi lungabuyeli ohlelweni nokuqinisekisa ukuthi uketshezi lungahamba luye endaweni engaguquki kuphela. Ukuvulwa nokuvalwa kwe-valve yokuhlola kuqedwa ngamandla okugeleza kwamanzi, ngakho-ke i-valve yokuhlola iwuhlobo lwe-valve othomathikhi. Ngenxa yezici zayo, isilinganiso sokusetshenziswa kwama-valve okuhlola empilweni sikhulu kakhulu.

Okubili. Isingeniso sokuhlukaniswa kwama-valve okuhlola

Ama-valve ethu okuhlola avamile futhi avame ukusetshenziswa ngokuvamile anezinhlobo ezintathu: uhlobo lokuphakamisa, uhlobo lwe-rotary kanye nohlobo lwe-disc. Okulandelayo ngokwehlukana kwethula izici zama-valve okuhlola amathathu ahlukene:

1. Isingeniso sokuphakamisa i-valve yokuhlola

I-valve yokuhlola i-Lift ihlukaniswe yaba izinhlobo ezimbili: enezingqimba futhi mpo ngokusho kwendlela yokubeka idivayisi. Kungakhathaliseki ukuthi ivundlile noma iqondile, ihamba eduze kwe-eksisi ukuze iqedele ukuvula nokuvala.

A. Kwamanye amaphrojekthi adinga ikhwalithi yobunjiniyela ephezulu ngokuqhathaniswa, ngokuvamile sisebenzisa amavalvu okuhlola athule ohlobo lokuphakamisa. Ngokuvamile, sifaka i-valve yokuhlola endaweni yokuphuma kwepompo;

B. Ngokuvamile, ama-valve okuhlola ukuthulisa ngokuvamile asetshenziswa ohlelweni lokuhlinzeka ngamanzi kanye ne-drainage yezakhiwo eziphakeme kakhulu. Ukuze ugweme ukuvinjelwa, i-valve yokuhlola ukuthulisa ngokuvamile ayisetshenziselwa ukukhipha indle;

C. Ukukhishwa kwendle kuphathwa ngevalvu yokuhlola evundlile. Ngokuvamile isetshenziswa ekusekeleni izindawo zasendaweni njengamaphampu akhipha indle kanye nendle.

2. Ama-valve okuhlola ama-Rotary ahlukaniswe abe izinhlobo ezintathu: i-valve eyodwa, i-valve ephindwe kabili kanye ne-valve eminingi ngokwezindlela zabo zokuhlola ezihlukene. Isimiso sabo sokusebenza ukuqedela ukujikeleza ngokusebenzisa isikhungo saso bese uqedela ukuvula nokuvala.

A. Ukusetshenziswa kwamavalvu okuhlola ama-rotary akushintshile, futhi ngokuvamile asetshenziswa ezinhlelweni zokuphakela amanzi emadolobheni, kodwa awafanele amapayipi okukhucululwa kwendle anenhlabathi eningi;

B. Phakathi kwama-valve okuhlola ama-rotary ahlukene, i-valve yokuhlola iqabunga elilodwa isetshenziswa kakhulu. Ayidingi ikhwalithi ephezulu yamanzi futhi ivame ukusetshenziswa ekunikezeni amanzi kanye ne-drainage, i-petroleum, amakhemikhali, i-metallurgical kanye neminye imisebenzi. Ikakhulukazi kwezinye izindawo ezivinjelwe, i-valve yokuhlola iqabunga elilodwa isetshenziswe kakhulu;

3, ukwethulwa kwe-valve yokuhlola uhlobo lwe-disc

A. Amavalvu okuhlola uhlobo lwediski ngokuvamile aqondile. Ama-valve okuhlola ama-valve amabili ohlobo lwe-Butterfly asetshenziswa kakhulu ekunikezeni amanzi kanye nokukhipha amanzi ezakhiweni eziphakeme, futhi uketshezi oluthile luyagqwala noma lusetshenziswa kwezinye izinhlelo zokukhucululwa kwendle;
