Entaaniso eri ahagati ya globe valve na gate valve, nobaasa kutoorana ota?

Ka tumanyise entaaniso eri ahagati ya globe valve navalvu y'omuryango.

01

Ekyombeko

Omwanya gw’okutaho ebintu gwaba gukye, ta omutima aha kutoorana:

Evalvu y'omuryangonikibaasa kwesiga pressure y‘ahagati kukinga gye aha mutwe gw‘okukinga, kugira ngu kihikire aha nkora y‘okutagira okusheeshasheesha. Waaba nookinga n’okukinga, omusingi gwa valve n’ekicweka ky’okukingaho eky’entebe ya valve nibiguma nibikwatagana kandi nibiteerana, n’ahabw’ekyo ekicweka ky’okukingaho nikiba kyorobi kujwara, kandi obu .valvu y'omuryangoeri haihi kukinga, entaaniso ya pressure ahagati y’omu maisho n’enyima y’omupiira ni mpango munonga, ekirikureetera okujwara kw’aha mutwe gw’okukinga kuba okw’amaani munonga.

Omubumbi w’ekitabo .valvu y'omuryangonikiija kuba kigumire kukira globe valve, kuruga omu kureeba, omu mbeera ya caliber emwe, valve y’omuryango eri ahaiguru kukira globe valve, kandi globe valve neekira .valvu y'omuryango. Okwongyera ahari ekyo, aba .valvu y'omuryangonigabaganisibwamu omuti ogurikwaka gye n’omuti ogurikwiragura. Valvu z’okukingaho tizirikukora.

Oku kirikukora

Globe valve ku erikwigurwa kandi ekingirwe, n’ekiti ekirikutunguuka, nikwo kugira ngu, enziga y’omu ngaro ku erikwetoorora, enziga y’omu ngaro neija kuhinduka kandi eimukye n’ekiti. Evalvu y'omuryangoni okuhindura omupiira gw’omu ngaro kureetera ekiti kya valvu kukora omuvuyo gw’okusimura, kandi omwanya gw’omupiira gw’omu ngaro gwonka gugume gutahindukire.

Emihendo y’okusheesheka neehinduka, naza valvu z'omuryangookwetenga kwigura omu bwijwire nari okukinga omu bwijwire, obwo globe valves zitarikukikora. Globe valve eine ahu erikutaaha n’okuruga, kandi .valvu y'omuryangotihariho byetaago by‘okutaaha n‘okuruga.

Okwongyera ahari ekyo, aba .valvu y'omuryangoaine embeera ibiri zonka: okukinga omu bwijwire nari okukinga omu bwijwire, kandi okuteera kw’okukinga n’okukinga empapura z’omuryango ni kwingi munonga, kandi obwire bw’okukinga n’okukinga nibumara obwire buraingwa. Omuvuyo gw‘okutambura gw‘empapura z‘okutambura z‘empapura z‘okutambura nigukye munonga, kandi empapura z‘okutambura z‘empapura z‘okutambura nizibaasa kwemerera omu mwanya gumwe omu kugyendera ahabw‘okuhindura omu nkora y‘okugyendera. Evalvu y'omuryangonikibaasa kukoresibwa omu kusharaho kwonka kandi tikiine mirimo endiijo.

Entaaniso omu kukora

Valve ya globe neebaasa kukoresibwa omu kusharaho n’okutegyeka okusheesheka. Okuzibira amaizi g’ekipande kya globe valve ni kihango munonga, kandi nikitwara obwire bwingi kwigura n’okukinga, kwonka ahabw’okugira ngu orugyendo oruri ahagati y’ekipande kya valve n’eitaka eririkukingaho ni rukye, orugyendo rw’okukinga n’okukinga nirukye.

Ahabw’okuba .valvu y'omuryangonikibaasa kwigurwa n’okukingwa omu bwijwire kyonka, kyaba kikingirwe omu bwijwire, okuzibira okusheesheka kw’omugati omu muhanda gw’omubiri gwa valvu kuri haihi 0, n’ahabw’ekyo okukinga n’okukinga kwa .valvu y'omuryangonikiija kukyendeeza munonga amaani, kwonka ekipande ky’omuryango kiri hare n’aha mutwe gw’okukinga, kandi obwire bw’okukinga n’okukinga nibumara obwire buraingwa.

Okutaho hamwe n'okugyendera

Ekirugire omuvalvu y'omuryangoomuhanda gw‘okusheesheka omu nshonda zombi nigushushana, tihaine ekirikwetengwa aha rubaju rw‘okutaaha n‘okuruga omu kutaho, kandi omugati nigubaasa kusheesheka omu nshonda zombi. Valve ya globe neeyetenga kuteebwaho omu muringo oguhikire kurugiirira aha rubaju orurikworekwa omusyo gw’omubiri gwa valve, kandi hariho enteekateeka erikureebwa gye aha rubaju oru globe valve erikutaaha n’okuruga, kandi orubaju rw’okusheesheka rwa globe valve nirutwarwa kuruga ahaiguru kuhika ahansi kurugiirira aha “three transformations valve” eya China’.

Valve y‘okukingaho eri ahansi omunda kandi eri ahaiguru aheeru, kandi kuruga aheeru hariho omupiira ogurikworeka gye ogutari aha rurengo rwa phase emwe. Evalvu y'omuryangoomuhanda gw’okusheesheka guri aha rubaju orurikuraba. Okusharara kwa .valvu y'omuryangoni mpango kukira ey’ekibumbe ky’ensi.

Okurugirira aha kureeba okuzibira okusheesheka, ku kirikukinguka omu bwijwire, okuzibira okusheesheka kw’omuhanda gw’omuryango nigukye, kandi okuzibira okusheesheka kw’omuhanda gw’okuremesa emigugu ni kwingi. Omubaro gw'okuzibira okusheesheka kwa buriijovalvu y'omuryangoni nka 0.08~0.12, amaani g’okukinga n’okukinga ni makye, kandi ahagati neebaasa kugyendera omu nshonda ibiri. Okuzibira okusheesheka kw’ebikwato bya globe ebya buriijo nikukira emirundi 3-5 ahari 100.ebikwato by’omuryango.Okwigura n’okukinga nibyetenga kugyemeserezibwa kukinga kubaasa kuhikiiriza okukinga, spool ya globe valve neekingwaho kimwe ku erikukwata aha itaka ry’okukinga, n’ahabw’ekyo okujwara kw’eitaka ry’okukinga ni kukye munonga, ahabw’okugyendera kwingi kw’amaani makuru kwongyera aha actuator ya globe valve eshemerire kuta omutima aha torju control.

Hariho emiringo ebiri y’okutaho globe valve, gumwe n’okugira ngu medium neebaasa kutaaha kuruga ahansi y’ekikopo, oburungi n’okugira ngu okupakira tikurikuteebwaho pressure valve yaaba ekingire, ekirikubaasa kwongyera aha myaka y’okuheereza kw’okupakira, kandi nikibaasa kugaruraho okupakira obu pipeline eri omu maisho ga valve eri ahansi ya pressure; Ekizibu kiri ngu torque y’okuvuga valve ni mpango, eri nk’emirundi 1 ey’okusheesheka kw’ahaiguru, amaani g’okuteera (axial force) g’omuti gwa valve ni maingi, kandi omuti gwa valve nigukora gye.

Nahabwekyo, omuringo ogu okutwarira hamwe nigukora gye aha nkora ya globe valves eziine oburaingwa bukye (DN50 nari ahansi), kandi globe valves eziri ahaiguru ya DN200 nizikoresa omugati ogurikutaaha kuruga ahaiguru. (Electric globe valves okutwarira hamwe nizikoresa omuhanda gw‘okutaaha kuruga ahaiguru.) Obuzibu bw‘omuringo gw‘okutaaha omu nkora kuruga ahaiguru nibuhakanisa kimwe omuringo gw‘okutaaha ahansi.

Okukingaho

Eitaka ry’okukingaho rya globe valve n’orubaju rukye rwa trapezoidal orw’omusingi gwa valve (okukira munonga reeba aha nkora y’omusingi gwa valve), omusingi gwa valve gwaheza kugwa, nikishushana n’okukinga kwa valve (entaaniso ya pressure yaaba eri mpango, buzima, okukinga tikugumire, kwonka ekirugire omu kukyebera ti kibi), .valvu y'omuryangonizikingirwa aha rubaju rw’empapura z’omuryango gw’omusingi gwa valve, ekirikukingwa tikiri kirungi nk’ekipande kya valve core, kandi valve core terikwija kugwa nk’ekipande kya valve core ekirikugyeragyeranisibwa n’okukinga kwa valve.
