Kuenzanisa Mhando Huru Ina

Unoziva sei kana vharuvhu yebhora yakavhurika kana kuti yakavharwa?

Wava kuda kucheka pombi, asi une chokwadi chekuti vharuvhu yakavharwa here? Chikanganiso chiri nyore apa chinogona kukonzera nyonganyonga huru, kukuvara kwemvura, kana kutokuvara.

Unogona kuona kanavharuvhu yebhorayakavhurika kana kuvharwa nekutarisa nzvimbo yemubato uchienzaniswa nepombi. Kana mubato wakaenzana nepombi, vharuvhu yakavhurika. Kana mubato wakamira wakatwasuka (uchiita chimiro che "T"), vharuvhu inovharwa.

Iyi ndiyo ruzivo rwakakosha uye rwakakosha kune chero munhu anoshanda nemavharuvhu ebhora. Nzvimbo yemubato chiratidzo chakananga chenzvimbo yebhora. Iyi dhizaini iri nyore ndeimwe yezvikonzero zvikuru zvinoita kuti mavharuvhu ebhora afarirwe. Hapana kufungidzira. Ndakambonzwa nyaya kubva kuna Budi nezvemushandi wechidiki wekugadzirisa panzvimbo yaishandiswa uyo aimhanya-mhanya. Akatarisa vharuvhu ndokufunga kuti yakanga yadzima, asi yakanga iri vharuvhu yekare yegedhi yaida kutendeuka kakawanda, uye aisagona kuona mamiriro ayo nemaziso. Akacheka ndokuzadza imba. Nevharuvhu yebhora, chikanganiso ichocho hachina kukwana kuita. Kutendeuka kwekota nenzvimbo yemubato yakajeka zvinopa mhinduro pakarepo, isina kujeka: mumutsara "watanga," mhiri "watanga." Iyi nzira iri nyore chishandiso chine simba chekuchengetedza.

Ndeupi musiyano uripo pakati peT type neL type ball valves?

Unofanira kutsausa kuyerera kwemvura, kwete kungoimisa chete. Kuraira vharuvhu yakajairwa hakushande, uye kuraira vharuvhu ine mapoinzi akawanda isina kunaka kunogona kutumira mvura kunzvimbo isiriyo zvachose.

Mhando yeT nemhando yeL zvinoreva chimiro chebhore riri mubhora revharuvhu ine nzira nhatu. Mhando yeL inogona kutsausa kuyerera kwemvura kubva pakupinda kwechinhu chimwe kuenda kune chimwe chezvipoko zviviri. Mhando yeT inogona kuita zvimwe chetezvo, uye inogona kubatanidza maport ese matatu pamwe chete.

Iyi inyaya inowanzo vhiringa vanhu vanotenga vharuvhu yavo yekutanga ine nzira nhatu.

Inogona kubatanidza pasi kuruboshwe, pasi kurudyi, kana kuti inogona kubatanidza kuruboshwe kurudyi (kupfuura pasi). Chinokosha ndechekuti ine nzvimbo inobatanidza maport ese matatu panguva imwe chete, zvichibvumira kusanganisa kana kutsausa. Chikwata chaBudi chinogara chichibvunza mutengi kuti: "Munofanira kusanganisa maflows here, kana kungochinja pakati pawo?" Mhinduro yacho inovaudza pakarepo kana T-Port kana L-Port ichidiwa.

Ndeupi musiyano uripo pakati pe trunnion ne floating ball valve?

Sisitimu yako inoshanda pasi pekumanikidzwa kwakanyanya. Kana ukasarudza vharuvhu yebhora yakajairika, kumanikidzwa kunogona kuita kuti zviome kutenderedza kana kutoita kuti zvisimbiso zvitadze kushanda nekufamba kwenguva.

Muvharuvhu inoyangarara, bhora "rinoyangarara" pakati pezvigaro, richisundwa nekumanikidzwa. Muvharuvhu yetrunnion, bhora rinosungirirwa nekachina kepamusoro nepasi (trunnion), iyo inotora kumanikidzwa uye inoderedza kushushikana pazvigaro.

Musiyano uripo ndewekushandisa simba. Muchidimbuvharuvhu yebhora inoyangarara^[7], kana vharuvhu yavharwa, kumanikidzwa kwekumusoro kunosunda bhora zvakasimba pachigaro chiri pasi. Simba iri rinogadzira chisimbiso. Kunyange zvazvo richishanda, izvi zvinogadzirawo kukweshana kwakawanda, izvo zvinogona kuita kuti vharuvhu iome kutenderedza, kunyanya muhukuru hwakakura kana pasi pekumanikidzwa kwakanyanya. Avharuvhu yakasungirirwa patrunnion^[8]inogadzirisa dambudziko iri. Bhora rinoiswa panzvimbo yaro nemidziyo ye trunnion, saka harisundirwe nekuyerera. Kudzvanywa uku kunosundidzira zvigaro zvine spring-loaded pabhora risingamire. Dhizaini iyi inotora simba guru, zvichiita kuti torque yakaderera (zviri nyore kutenderedza) uye kugara kwenguva refu kwechigaro. Ndokusaka kumashandisirwo emaindasitiri ane pressure yakakwira, kunyanya muindasitiri yemafuta negasi, mavharuvhu e trunnion ndiwo anodiwa. Kune akawanda masisitimu ePVC, kudzvanywa kwacho kwakaderera zvekuti vharuvhu inoyangarara inoshanda zvakanaka.
