I-Manual Ball Valve

Ngingabona kanjani ukuthi i-valve yebhola eyenziwa ngesandla ivuliwe noma ivaliwe?

Ama-valve amaningi ebhola asebenza ngesandla afika nesibambo se-lever esiqondile njengenkomba evamile. Uma isibambo sima ngokuhambisana nomzimba wevalvu kanye nepayipi, ibhobo langaphakathi liqondana nepayipi, okusho ukuthi ivalvu ivuleke ngokugcwele ukuze okuphakathi kudlule. Uma uzungezisa isibambo ngamadigri angu-90 ngokuphambana nepayipi, imbobo yebhola ijika ibe yi-pendicular ukuze ihambe futhi inqamule uketshezi ngokuphelele, okuyisimo esivaliwe. Inombolo encane yama-valve yezandla enezintambo ezincane zisebenzisa isondo lesandla lohlobo lwe-T; ungabhekisela kumcibisholo omakwe okuthi VULA/VALA ophrintwe kubhonethi yevalvu ukuze wahlulele isimo sokushintsha kalula.

Izimfanelo Ezibalulekile

Kufanele ngisebenzise nini i-valve yebhola yezandla phezu kwe-othomathikhi?

Ama-valve ebhola enziwa ngesandla angcono kakhulu ukukhetha amasayithi anemisebenzi yokushintshashintsha njalo. Emapayipini amagatsha amancane, amapayipi ezinto ezisizayo kanye nezinhlelo ezincane zamanzi/zamakhemikhali lapho izisebenzi zisebenza khona njalo esizeni, izinhlobo ezenziwa ngesandla zinciphisa izindleko ezengeziwe kuma-actuator kagesi noma omoya futhi zenze ukulungiswa kwakamuva kube lula. Aphinde asebenze kahle ezindaweni zokunqamula izimo eziphuthumayo: lapho amandla noma umoya ocindezelwe ehluleka futhi ama-valve azenzakalelayo elahlekelwa ukulawula, ama-valve okwenziwa ngesandla asebenza njengokuvala isipele ngokuthembekile. Ngaphandle kwalokho, amaphrojekthi anendawo elinganiselwe yokufaka noma ongenawo umthombo wamandla otholakalayo akhetha ama-valve amabhola okwenziwa ngesandla esikhundleni sezinguqulo ezizenzakalelayo.

Yiziphi izinhlobo eziyinhloko zama-valve ebhola lezandla?

Njengoba sihlukaniswa ngesakhiwo somzimba, sihlinzeka ngokuyinhloko ama-valve ebhola anocezu olulodwa, anezingcezu ezimbili nantathu; imiklamo ye-split-body isiza ukuhlakazeka okusheshayo ukuze kufakwe uphawu lwangaphakathi ngaphandle kokukhipha yonke i-valve kumapayipi. Ngesitayela sokuxhuma ekugcineni, kukhona iziphetho ze-NPT/BSP ezinentambo zomugqa omncane neziphetho ezivulekile zamapayipi ezimboni ezinosayizi omkhulu. Ngokusekelwe ezintweni zokuvala, zihlukaniswa zibe uphawu oluthambile lwe-PTFE lwe-medium evamile ehlanzekile kanye nensimbi eqinile yokuqinisa izinga lokushisa eliphezulu noma izimo zoketshezi olubi.

Ingabe i-valve yebhola eyenziwe ngesandla kulula ukuyigcina?

Ama-valve ebhola enziwa ngesandla angenye yezinhlobo zama-valve zezimboni ezingalungiswa kakhulu emakethe. Ngokungafani nama-valve kagesi noma we-pneumatic, aziqukethe izingxenye zikagesi eziyinkimbinkimbi, amasilinda omoya, izinzwa noma amamojula okulawula, okunciphisa kakhulu izinga lokuhluleka. Isakhiwo sonke silula futhi sinembile. Ukunakekelwa kwansuku zonke kudinga kuphela ukuhlanzwa kwendawo okuvamile kanye nokuhlola amabhawodi axegayo noma ukuguga kancane. Uma kudingeka ukushintshwa kwama-gaskets noma izindandatho zokuvala, izisebenzi ezisendaweni zingaqeda ukulungisa ngokushesha ngaphandle kochwepheshe abangochwepheshe noma imishini ekhethekile yokususa iphutha. Inezindleko eziphansi zokunakekela kanye nempilo ende yesevisi yokusebenza kwepayipi lesikhathi eside.Ungaqhathanisa ukucaciswa, amanani kanye nemingcele yezobuchwepheshe ngokuqondile nefekthri yethu ye-Huadu Valve e-Wenzhou. Singabakhiqizi bangempela abanikeza isitoko sendawo kanye nensizakalo ye-OEM eyenziwe ngokwezifiso. Ungase futhi uhlole imininingwane yomkhiqizo wethu ezinkundleni zokuxhumana ze-B2B ezivamile. Ukuze uthole ukuthengwa kwendawo, sebenzisana nabasabalalisi besifunda bevalvu yezimboni nabahlinzeki bezingxenye zamapayipi ezweni lakini ukuze uqhathanise ukusebenza kwemikhiqizo ehlukene kanye nekhotheshini.

Ingabe ama-valve ebhola okwenziwa ngesandla angasetshenziselwa isevisi yokudonsa?

Ama-valve ebhola okwenziwa ngesandla aklanyelwe ngokuyinhloko ukuthi avuleke ngokugcwele futhi aphelele ekunqamulweni kokulawula, anganconyelwe ukusetshenziswa kwesikhathi eside kwengxenye ye-throttling. Uma igcinwe ivulekile isikhathi eside, uketshezi luzolokhu luthinta futhi luwashe ibhola nendawo evalekayo, okubangele ukuguga ngaphambi kwesikhathi, ukuklwebheka kanye nokuvuza okuphakathi. Ukuze kulungiswe ukugeleza kwesikhathi esifushane ngezikhathi ezithile, kungabona ukugobhoza okulula; kodwa ngokulawulwa kokugeleza okuzinzile kanye nesikhathi eside, ama-valve okulawula ochwepheshe afaneleka kakhulu.
