Ko te waro SDV (Kati Raro) he takirere he tuwhera te ahua-V ki tetahi taha o te poroporo haurua.Ma te whakatikatika i te whakatuwheratanga o te pupuhi, ka hurihia te waahi whakawhiti o te rere o te reo ki te whakatika i te rere.Ka taea hoki te whakamahi mo te mana whakawhiti ki te mohio ki te whakatuwhera me te kati ranei o te paipa.He painga te horoi whaiaro, ka taea te whakatutuki i te whakarereketanga iti o te rere i roto i te waahanga whakatuwhera iti, he nui te owehenga whakarite, e tika ana mo te muka, matūriki pai, slurry media.
Ko te whakatuwheratanga me te kati o te waahi poroporo momo V he porowhita me te awa porohita, a ko nga tuakoi e rua e honoa ana e te peera me te huri i te 90 ° ki te whakatutuki i te kaupapa o te whakatuwhera me te kati.
Kei te whakamahia nuitia i roto i te punaha whakahaere aunoa o te hinu, te ahumahi matū me etahi atu.

1. he iti te parenga o te wai, he nui te whakarea rere, he teitei te tauwehenga whakarite.Ka taea te tae ki te: 100: 1, he nui ake te rahi atu i te owehenga whakatika o te reera whakahaere tuuru kotahi, te takirere whakahaere e rua nga nohoanga me te reera whakahaere ringaringa.Ko ona ahuatanga rere he rite te ōrau.
2. hiri pono.Ko te reanga rerenga o te hanganga hiri pakeke whakarewa ko te Class IV o GB / T4213 "Pneumatic Control Valve".Ko te karaehe turuturu o te hanganga hiri ngohengohe ko te Class V, Class VI ranei o GB / T4213.Mo te hanganga hiri pakeke, ka taea te hanga i te mata hiri o te poroporo ki te whakakikorua chromium pakeke, te whakakikorua i te carbide cimented i runga i te cobalt, te rehu i te tungsten carbide whakakikorua i te kakahu, me etahi atu, hei whakapai ake i te oranga o te hiri o te hiri matua.
3. ka tuwhera me te kati tere.V-momo pōro takirere he koki whiu whiu, mai i te tino tuwhera ki te tino kati spool Koki 90°, me te AT piston pneumatic actuator ka taea te whakamahi mo nga tikanga tapahi tere.I muri i te whakauru i te tuunga hiko hiko, ka taea te whakatika kia rite ki te tohu analog 4-20Ma ōwehenga.
4. pai te mahi aukati.Ka mau te spool i te 1/4 te ahua hemispherical me te hanganga nohoanga unilateral.Ina he matūriki totoka kei roto i te reo, ka kore te aukati i te kohao ka rite ki nga marere poroporo O-momo noa.Karekau he mokowhiti i waenga i te poroi ahua-V me te nohoanga, he nui te kaha kutikuti, he pai rawa mo te whakahaere i te whakatārewatanga me nga matūriki totoka kei roto he muka, he matūriki totoka iti ranei.I tua atu, kei reira nga waahi poroporo V-ahua me te spool o te ao, he pai ake mo nga ahuatanga o te pehanga teitei ka taea te whakaiti i te whakarereketanga o te matua o te poihe ka puta te rereketanga o te pehanga teitei.Ka tangohia e ia he hiri nohoanga kotahi, he hanganga hiri nohoanga rua ranei.Ko te puera poroporo V-ahua ki te hiri nohoanga rua te nuinga e whakamahia ana mo te whakahaerenga rerenga reo ma, a ko te reo me nga matūriki ka puta te kino o te kati i te kohao waenga.
5. V-momo poroporo valve ko te hanganga pōro pūmau, ka utaina te nohoanga ki te puna, a ka taea te neke haere i te ara rere.Ka taea te utu aunoa i te kakahu o te spool, ka roa te ora o te ratonga.Ko te puna he puna hexagonal, puna ngaru, puna kōpae, puna kōpeke porotakaroa me etahi atu.A, no te mea he iti nga poke o te reo, he mea tika ki te taapiri i nga mowhiti hiri ki te puna hei tiaki i nga poke.Mo nga tuuru takirua kua hirihia nga reera poipoi-V o te ao, ka whakamahia te hanganga poipoi maanu.
6. ina he ahi me te anti-pateko whakaritenga, hanga te matua takirere ki te whakarewa hiri hanganga hiri, te whakakī i hanga o te kauwhata hangore me ētahi atu rauemi ātete pāmahana teitei, me te kakau takirere he pokohiwi hiri.Me tango i nga tikanga kawe hiko i waenga i te tinana takirere, te kakau me te porowhita.Kia rite ki te hanganga ahi-aukati GB / T26479 me nga whakaritenga antistatic GB / T12237.
7. V-ahua poroporo takirere rite ki te hanganga taatiraa rerekē o te matua pōro, i reira he kore hanganga keokeo, hanga kerekere kotahi, hanganga kerekere rua, e toru hanganga kerekere.Ko te hanganga e whakamahia nuitia ana he kore noa.Ka taea e te hanganga rereke te tuku tere i te pupuhi mai i te nohoanga ka whakatuwheratia, ka whakaiti i te kakahu o te mowhiti hiri me te whakawhānui ake i te oranga o te ratonga.Ina katia, ka taea te whakaputa i te kaha keokeo hei whakarei ake i te paanga hiri.
8. Ko te aratau taraiwa o te V-type ball valve he momo kakau, he tuku taputapu kutukutu, pneumatic, hiko, hydraulic, electro-hydraulic hononga me etahi atu momo taraiwa.
9.V-momo hononga takirere pōro he hononga flange me te hononga rawhi e rua ara, mo te porowhita o te ao, te hanganga hiri nohoanga rua me te hononga miro me te whiri turanga, te reke me etahi atu tikanga hononga.
10.ceramic pōro takirere hoki he V-āhua hanganga matua pōro.He pai te kakahu, engari ano hoki te waikawa me te waikura alkali, he pai ake mo te whakahaere i nga purongo maramara.He hanganga matua poroporo te ahua-V o te rewharewha rewharewha, e whakamahia ana mo te whakahaere me te whakahaere i te waikawa me te kawakore.Ko te awhe tono o te momo V-momo valve he nui ake te whanui.
Ko te ratonga muri-hoko o te SDV valve (Shut Down Valve) (V tauranga) he mea tino nui, no te mea ko te wa me te whai hua i muri i nga ratonga hokohoko ka taea te whakarite i tana mahi mo te wa roa me te pumau.Ko nga mea e whai ake nei ko nga korero o muri i te hokonga o etahi maru poipoi maanu:
1.Installation and commissioning: Ka haere nga kaimahi ratonga muri-hoko ki te waahi ki te whakauru me te patuiro i te paera poipoi maanu hei whakarite i tana mahi tuturu me te mahi noa.
2.Maintenance: Kia mau tonu te reera poipoi maanu ki te whakarite kei te pai te mahi me te whakaheke i te reeti kore.
3.Troubleshooting: Ki te rahua te takirere pōro mānu, ka mahi nga kaimahi ratonga muri-hoko i runga i-pae rapurongoā i roto i te wa poto taea ki te whakarite i tona mahi noa.
4.Whakahoutanga hua me te whakamohoatanga: Hei whakautu ki nga rauemi hou me nga hangarau hou e puta mai ana i te maakete, ka tukuna e nga kaimahi ratonga muri-hoko te whakahou me te whakahou i nga otinga ki nga kaihoko ki te whakarato ki a raatau nga hua pai ake.
5. Te whakangungu matauranga: Ka whakawhiwhia e nga kaimahi ratonga muri-hoko nga whakangungu matauranga ki nga kaiwhakamahi ki te whakapai ake i te whakahaere me te taumata tiaki o nga kaiwhakamahi e whakamahi ana i nga reera poipoi maanu.I roto i te poto, te ratonga muri-hoko o te piha pōro mānu kia taurangi i roto i nga ahunga katoa.Ma tenei anake ka taea e nga kaiwhakamahi te wheako pai ake me te haumaru hoko.
