Ob lub pob valve muaj ob lub cev tseem ceeb uas ntsia hlau ua ke, dai lub pob thiab cov ntsaws ruaj ruaj hauv. Qhov kev tsim no muaj zog tshaj li ib lub valve thiab tso cai rau kev kho, txawm hais tias nws yuav tsum xub muab tshem tawm ntawm lub raj xa dej.

Ob lub pob valve yog qhov tseeb ua haujlwm hauv lub ntiaj teb cov kav dej. Nws yog ib qho ntawm ntau hom kev sib tham nrog kuv cov neeg koom tes, xws li Budi, tus thawj tswj kev yuav khoom hauv Indonesia. Nws cov neeg siv khoom, uas feem ntau yog cov neeg cog lus dav dav thiab cov neeg xa khoom, xav tau cov kev daws teeb meem zoo tshaj plaws rau kev ua haujlwm txhua hnub. Qhov ob-daim tsim hits qhov chaw qab zib zoo kawg nkaus. Nws muaj kev txhim kho tseem ceeb hauv lub zog thiab kev pabcuam tshaj li qub tshaj plaws yam tsis muaj tus nqi siab dua ntawm cov qauv kev lag luam.

Kev tsim kho ntawm aob daim valveyog nws lub ntsiab feature. Xav txog tias lub valve lub cev yog ua nyob rau hauv ob seem. Qhov loj dua tuav lub qia thiab kov, thaum qhov me me yog qhov tseem ceeb ntawm lub hau threaded. Thaum lawv tau screwed ua ke, lawv clamp cia rau ntawm lub pob thiab cov rooj zaum mos (feem ntau yog ua los ntawm PTFE) uas tsim lub foob. Qhov kev tsim lub cev threaded no muaj zog ntau dua li ib lub pob valve, qhov twg lub pob yog ntxig los ntawm qhov qhib me me, feem ntau xav tau lub pob me me (qhov chaw nres nkoj txo). Kev tsim kho ob-thooj tso cai rau lub pob loj dua, "tag nrho qhov chaw nres nkoj", txhais tau tias lub qhov hauv lub pob yog qhov loj tib yam li cov yeeb nkab, uas ua rau kom zoo dua nrog kev poob siab. Yog tias lub foob puas tau hnav, koj tuaj yeem tshem tawm lub cev, hloov cov khoom, thiab muab rov qab rau hauv kev pabcuam. Nws yog ib qho chaw nruab nrab zoo rau ntau tus Budi cov neeg siv khoom uas xav tau lub valve uas yog ob qho tib si tawv thiab kho tau.

Dab tsi yog qhov txawv ntawm hom 1 thiab hom 2 pob valve?

Cov ntsiab lus no tsis yog hais txog kev tsim kho lub cev (xws li ob-thooj) tab sis los tsim cov tiam neeg, feem ntau ntawm lub koomhaum tiag tiag li qub. "Type 21" yog kev lag luam luv luv rau kev tsim qauv niaj hnub nrog txhim kho kev nyab xeeb thiab siv tau zoo.

Nws yog ib qho tseem ceeb heev kom tsis txhob cuam tshuam lub cev style nrog cov "hom" tus lej. Lub "ob-thooj" valve piav qhia tias lub cev tsim lub cev li cas. Cov ntsiab lus zoo li "Hom 21," ntawm qhov tod tes, piav qhia txog cov txheej txheem tshwj xeeb ntawm cov yam ntxwv niaj hnub no, thiab lawv yuav luag ib txwm pom ntawm peb lub koomhaum tiag tiag li qub. Kuv yuav tsum tau qhia meej qhov no rau Budi pab pawg qee zaum. Ib tus neeg siv khoom tuaj yeem thov rau ib qho"Hom 21 ob-daim valve,"tab sis cov yam ntxwv no yog ib feem ntawm cov chav kawm valve sib txawv. Qhov tseem ceeb tshaj plaws ntawm hom 21 style yog qhovblock-safe union txiv ntoo, uas tiv thaiv lub valve los ntawm kev yuam kev unscrewed thiab qhib thaum lub kaw lus nyob rau hauv siab. Qhov no yog qhov tseem ceeb ntawm kev nyab xeeb. Lawv kuj feem ntau suav nrog ob lub qia O-rings rau kev sib khi zoo dua thiab ib qho kev sib txuas ua ke rau kev ntxiv cov actuator. Cov no yog cov yam ntxwv zoo tshaj plaws rau cov haujlwm uas xav tau tshaj plaws, thaum tus qauv ob-thooj valve yog qhov kev xaiv zoo rau kev ua haujlwm dav dav.
