Iimpawu zeevali zeplastiki

Ilungu lokuvula kunye nokuvala (ibhola) liqhutywa yi-valve stem kwaye ijikeleza i-axis ye-valve stem. Ikakhulu isetyenziselwa ukunqunyulwa okanye ukudibanisa i-Pipeliline kwi-Pipeline, inokusetyenziselwa ukumiselwa komhlaba, kulawulo, olu hlobo lwevalve kwiplateline ngokubanzi kufuneka ifakwe ngokuthe tye.

Iimpawu zeplastiki yeplastiki:

(1) Uxinzelelo oluPhezulu lokuSebenza: Uxinzelelo olusebenzayo lwezixhobo ezahlukeneyo kubushushu obuqhelekileyo banokufikelela kwi-1.0PA.

(2) Ubushushu babanzi bokusebenzisa: Ukusetyenziswa kweqondo lokushisa lwePVDF yi-12 ℃ ~ + 120 ℃; Iqondo lokushisa le-RPP ngu -0 ℃ ~ + 95 ℃; Iqondo lokushisa le-UPVC ngu-50 ℃ ~ + 95 ℃.

.

(5) Ukusebenza kakuhle kweekhemikhali I-PPR isetyenziselwa ukutya, isiselo, amanzi empompo,

Amanzi acocekileyo kunye neminye imibhobho yolwelo kunye nezixhobo ezineemfuno zococeko, zinokusetyenziselwa imibhobho engamanzi kunye nezixhobo ezinobunkunkqele obuncinci;

I-RPP, i-UPV, i-PVDF, i-CPVC isetyenziselwa ukuvela kwe-alfayili (igesi) ye-acid eyomeleleyo, i-alkali eyomeleleyo kunye ne-acid exubeneyo.

I-valve yeplastiki yeplastiki yezona mpawu ziphambili zeflethi, indawo enokutyhafa, elula, ukulungiswa okukhoyo, ukungasebenzi kakuhle kunye nokugcinwa ngokulula kunye nokugcinwa kwamanzi, i-syilevent Kwaye igesi, njengokusebenza ngokubanzi, kodwa ilungele iimeko zomsebenzi zemithombo yeendaba, njengeoksijini, i-hydrogen peroxide, i-methane nethylene, isetyenziswa ngokubanzi kumashishini ahlukeneyo. Umzimba we-valve webhola unokudibana okanye udityanisiwe.
