Chemical Indasitiri Yakananga Gedhi Valve

Isu tiri nyanzvi yekugadzira valve yakabata ISO, API uye CE certification. Isu pachedu midziyo yekugadzira yepamusoro uye yakazara seti yemhando yekudzora masisitimu. Isu tinogashirawo maOEM neODM maodha, ane inochinjika yakaderera odha huwandu. Mavharuvhu edu emakemikari asingadziviriri anotengeswa kunze kwenyika uye anokunda kuzivikanwa kwakakura kubva kune vatengi veindasitiri yemakemikari.

Hunhu Hunokosha

Ndezvipi zvakakosha zveiyi Chemical Industry Specific Gate Valve, yakasiyana neyakajairwa mavharuvhu egedhi?

Mavharuvhu egedhi akajairwa anonyanya kutarisisa pamvura yenguva dzose, chiutsi uye svikiro remafuta, ukuwo kemikari yedu yakatsaurirwa gedhi vharuvhu inokwidziridzwa yakanangana nekuora kwemakemikari media. Isu tinokwenenzvera kusarudzwa kwezvinhu, kuisa chisimbiso uye yemukati chiteshi chimiro. Muviri wevharuvhu wakakora kuti urambe kukukurwa kwepakati; iyo wedge gedhi uye yekuisa chisimbiso inotora anti-corrosion yekusimbisa kurapwa, iyo yakatwasuka-kuburikidza yemukati chiteshi inokwenenzverwa zvakanaka kuderedza kunamatira kwezvinhu uye kuunganidzwa kwezvisaririra, izvo zvinodzivirira kudzivirira crystallization, kuyera uye kuvharika kunowanzoonekwa mumapaipi emakemikari. Inogona kushanda zvakadzikama neasidhi, alkali, brine uye akasiyana makemikari akasanganiswa zvinwiwa, zvinodarika zvakajairwa magedhi mavharuvhu mu-anti-corrosion uye kwenguva yakareba-inoenderera mberi kushanda kwekuita.

Ndezvipi zvingasarudzwa zviripo zvemakemikari indasitiri chaiwo gedhi mavharuvhu, uye ndeapi mamiriro ekushanda akakodzera chinhu chimwe nechimwe?

WCB kabhoni simbi inoshamwaridzana nebhajeti. Inoshanda zvakanaka nezvinwiwa zvinoparadza zvinyoro uye zvinonyungudutsa zvisina kwazvakarerekera, uye inokodzera kudzika-tembiricha yekemikari pombi dzekutakura, dzinowanzo shandiswa mapaipi ekubatsira mune zvakajairika makemikari zvidyarwa.

CF8 (304 Stainless simbi) ndiyo yakajairika anti-corrosion zvinhu. Inoita zvakatsiga kana ichitakura asidhi isina simba, alkali isina simba uye makemikari emazuva ese zvinhu, uye inowanzo gamuchirwa pamapaipi emvura yetsvina yemakemikari.

CF8M (316L simbi isina tsvina) inozvirumbidza nepamusoro pekudzivirira. Inogona kumirisana nehydrochloric acid, dilute sulfuric acid, brine uye zvimwe zvinhu zvinoparadza zvakanyanya, zvichiita kuti ive sarudzo yepamusoro yemakemikari uye mitsara yekugadzira mishonga.

Isu tinokwanisa zvakare kugadzirisa Hastelloy, Monel uye zvimwe zvakakosha alloy zvinhu zvekupedzisira-zvinoodza zvakanyanya kushanda mamiriro pakudiwa.

Iyo kemikari gedhi vharafu inotsigira bidirectional chisimbiso? Kudonha kunoitika mushure mekushandisa kwenguva refu?

Yese kemikari yakatsaurirwa mavharuvhu egedhi anotora akakura akasimbisa wedge yekuzvivharira chimiro, kuona yakavimbika bidirectional tight shutoff. Hazvina mhosva kuti yepakati inoyerera ichienda mberi kana kudzosera kumashure mukati mepombi, vharafu inogona kuchengetedza zero kudonha mushure mekuvharwa zvakazara. Iyo yekuisa chisimbiso inoshandisa anti-corrosion yakaoma-yakatarisana nekurapa, iyo isingapfeki uye inodzivirira kukukurwa. Chero bedzi ichishanda mukati meyakayerwa kudzvanywa uye tembiricha renji, yakajairwa kemikari yepakati haizokonzerese kutadza kuvhara nekukurumidza, uye yakagadzikana yekuisa chisimbiso kuita inogona kuchengetedzwa kwenguva yakareba inoenderera kugadzirwa.

Ndeapi magiredhi ekumanikidza uye caliber saizi iripo? Zvisiri-standard customized sizes zvingagadzirwa here?

Yedu yakajairwa mavharuvhu egedhi anotora ANSI 150LB uye 300LB kudzvanywa kwakatemwa, saizi inovhara DN15 kusvika kuDN600 uye inokodzera akawanda akajairika mapombi emakemikari zvakananga. Tinogona kugadzira mavharuvhu ane akakosha mazinga ekumanikidza uye hukuru husina kujairika pakukumbira. Zvinoenderana neyako saiti yekuisa nzvimbo uye chaiyo yekushanda nharaunda, fekitori yedu inogona kugadzira ega mavharuvhu emagedhi kuti akwane musangano wako wakasarudzika pombi kurongeka.

Ndeapi tembiricha renji anogona aya makemikari indasitiri chaiwo gedhi mavharuvhu kushanda mukati zvakajairwa?

Yakajairika PTFE nyoro chisimbiso shanduro inoshanda zvakatsiga kubva -20 ℃ kusvika 180 ℃, yakanaka kune yakawanda kamuri-tembiricha yekugadzira makemikari mitsara. Tsika simbi yakaoma chisimbiso idzo dzinogona kumira kupisa kusvika ku450 ℃, yakakodzera kune yakakwirira-tembiricha kemikari reaction mapaipi. Isu tinopawo akakosha akadzika-tembiricha ekuisa chisimbiso zvimisikidzo anoshanda kuunza liquefied makemikari zvinhu pasi pe cryogenic mamiriro.

Unogona here kupa OEM & ODM kugadzirisa masevhisi? Ndezvipi zvigadziriso zvemunhu zvinotsigirwa?

Isu tinopa inochinjika yakazara OEM uye ODM kugadzirisa sevhisi. Isu tinokwanisa kutsiva anti-corrosion alloy zvinhu, kumisikidza yakakwirira-tembiricha / kusapfeka-inodzivirira yakakosha yekuisa chisimbiso zvikamu, kunyora ega emhando marogo pamiviri yevharuvhu, kugadzirisa pamusoro peanti-corrosion coating, kugadzirisa ekunze kurongedza zviyero, shandura flange yekubatanidza zviyero. Tinogona kuburitsa mavharuvhu zvizere zvinoenderana neako einjiniya kudhirowa uye yakadzama tekinoroji paramita kuti ienderane yakasarudzika kemikari purojekiti zvinodiwa.

Ndezvipi zvitupa uye ongororo yefekitori iyo mavharuvhu apedzwa achapfuura nawo asati aburitswa?

Fekitori yedu inobata ISO, CE uye API zviri pamutemo zvitupa. Yese kemikari gedhi vharafu inoenda nemubvunzo dzakasimba imwe neimwe isati yatumirwa: shell hydrostatic pressure test, yekuisa chisimbiso bvunzo, kuvhura & kuvhara kushanda kuneta bvunzo, mbishi zvinhu spectrum ongororo kusimbisa kuumbwa kwezvinhu. Zvigadzirwa zvisina kukodzera zvichabviswa zvakananga, mavharuvhu ese akaunzwa anosangana nedzimwe nyika makemikari ekuchengetedza zviyero.

Sample sevhisi iripo yekuedzwa kwekuita isati yaiswa yakawanda odha?

Samples dzemhando uye corrosion resistance test dziripo. Yakajairika mu-stock mavharuvhu anogona kuendeswa nekukurumidza kune yako lab uye pane-saiti bvunzo bvunzo. Kana iwe uchida akagadziridzwa akakosha emhando masampuli, isu ticharonga diki-batch sampuli kugadzirwa, simbisa yakajeka kugadzirwa kutenderera newe pamberi. Iwe unogona kuisa maodha akaomeswa akawanda chete mushure mekunge waedza uye nekusimbisa sampuli inosangana nezvido zvako zvekushanda.

Ndeapi akakosha ekugadzirisa mapoinzi ekuwedzera hupenyu hwesevhisi yemakemikari indasitiri chaiwo gedhi mavharuvhu?

Tarisa handwheel kushanda kuchinjika nguva dzose, ita shuwa kuti gedhi rinosimudza zvakanaka pasina jamming inokonzerwa nepakati crystallization;

Chenesa yakasara kemikari yepakati yakasungirirwa pavharuvhu yepamusoro uye yemukati chiteshi nguva nenguva kudzivirira kukukurwa kwenguva refu kwekuora;

Wedzera yakakosha anti-corrosion lubricating girisi kune yevhavha hunde nguva nenguva, kudzivirira ngura uye stem clamping;

Kurambidza zvakasimba overpressure uye over-temperature oparesheni kupfuura valve rated parameters;

Vhara vharuvhu zvakasimba panguva yekuvhara kwenguva refu kuti udzivise corrosive medium kunyudza nzvimbo yekuvharira kwenguva yakareba.

Ndeapi mamiriro eindasitiri yemakemikari aya mavharuvhu emagedhi anonyanya kushandiswa mukati?

Iwo anoshandiswa zvakanyanya mumitsetse yakanaka yekugadzira makemikari, petrochemical mapaipi, mishonga yemakemikari kugadzirisa, makemikari ekuchengetedza zvinhu & kutakura, kurapwa kwemakemikari tsvina, kugadzira fetereza, kugadzira zvinhu zvitsva uye mamwe mapurojekiti emakemikari akajairika.
