Hunhu hwemavharuvhu
Mavharuvhu maitiro anowanzo kuve emhando mbiri, hunhu hwesevhisi uye chimiro chechimiro.
Shandisa maitiro: inotarisa kushandiswa kukuru kwekushanda kwevhavha uye kushandiswa kwehuwandu hwekushandiswa, ndeyemhando yekushandiswa kwevhavha ndeye: chikamu chevhavha (yakavharwa yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,nezvimwewo); Chigadzirwa mhando (gedhi vharafu, globe vharafu, butterfly vharafu, bhora vharafu, etc.); Izvo zvikamu zvikuru zvevhavha (muviri wevhavha, chivharo, stem, disc, sealing surface) zvinhu; Valve transmission mode, nezvimwewo.
Chimiro chemaitiro: inosarudza kuiswa kwevhavhavha, kugadzirisa, kugadzirisa uye dzimwe nzira dzemamwe maitiro ezvimiro, zvechimiro chechimiro ndeiyi: kureba kwevhavhavha uye urefu hwose, uye fomu yekubatanidza pombi (flange connection, thread. kubatanidza, hoop yekubatanidza, yekunze tambo yekubatanidza, welding yekupedzisira yekubatanidza, nezvimwewo); Chimiro chekuisa chisimbiso pamusoro (isa mhete, mhete yeshinda, yakatarisana, yekupfapfaidza welding, muviri wemuviri); Valve stem chimiro fomu (inotenderera tsvimbo, inosimudza tsvimbo), nezvimwe.
Maitiro ekusarudza mavharuvhu uye hwaro
Matanho ekusarudza:
1, vharavha yakajeka mumidziyo kana kushandiswa kwechigadziro, sarudza mamiriro ekushanda evhavha: inoshandiswa pakati, kushanda kumanikidziro, kupisa kwekushanda uye zvichingodaro.
2, sarudza dhayamita yezita uye nzira yekubatanidza yepombi inobatanidza nevhavha: flange, shinda, welding, nezvimwe.
3, sarudza nzira yekushandisa vharafu: manual, magetsi, electromagnetic, pneumatic kana hydraulic, magetsi ekubatanidza kana electro-hydraulic linkage.
4, zvinoenderana nepombi yekufambisa svikiro, kumanikidza kushanda, tembiricha yekushanda kuona yakasarudzwa vharafu goko uye zvikamu zvemukati zvezvinhu: grey cast iron, inogoneka yakakandwa simbi, ductile iron, kabhoni simbi, alloy simbi, stainless acid-resistant simbi, copper alloy, nezvimwewo.
5, sarudza rudzi rwevhavha: yakavharwa yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha kumiwa.
6, tarisa rudzi rwevharuvhu: gedhi vharafu, globe vharafu, bhora vharafu, butterfly vharafu, throttle vharafu, kuchengetedza vharafu, kumanikidza kudzikisa vharafu, musungo weutsi, nezvimwe.
7, sarudza maparamendi evharuvhu: kune otomatiki mavharuvhu, zvinoenderana nezvinodiwa zvakasiyana kuona inobvumidzwa kuyerera kuramba, kubuda simba, kumashure kumanikidzwa, nezvimwewo, uye wozoona dhayamita rezita repombi uye dhayamita yegomba rechigaro chevhavha. .
8, sarudza iyo yakasarudzwa geometric parameters yevharuvhu: chimiro urefu, flange yekubatanidza fomu uye saizi, vhura uye uvhare nhanho yehurefu hwevharuvhu yehukuru, kubatana kwegomba rebhoti saizi uye nhamba, ukuru hwevharuvhu yese chimiro.
9, kushandiswa kweruzivo rwuripo: vharafu chigadzirwa catalog, vharafu chigadzirwa samples uye zvimwe zvakakodzera mavharuvhu zvigadzirwa.
Kusarudzwa kwevhavha nheyo:
Mukunzwisisa kwekusarudzwa kwematanho evharuvhu, asiwo inofanira kuwedzera kunzwisisa hwaro hwekusarudzwa kwemavharuvhu.
1, kushandiswa kwevhavha yakasarudzwa, mamiriro ekushanda uye maitiro ekutonga.
2, hunhu hwesvikiro rekushanda: kumanikidza kushanda, tembiricha yekushanda, corrosion performance, ingave ine zvimedu zvakasimba, ingave yepakati ine muchetura, ingave inopfuta, inoputika yepakati, yepakati viscosity zvichingodaro.
3, iyo valve fluid maitiro ezvinodiwa: kuyerera kuramba, kubuda simba, kuyerera maitiro, kuvhara giredhi uye zvichingodaro.
4, saizi yekuisa uye yekunze saizi zvinodiwa: zita dhayamita, kubatana nepombi uye saizi yekubatanidza, saizi yekunze kana uremu muganho.
5. Zvimwe zvinodiwa pamusoro pekuvimbika, hupenyu hwebasa uye kuputika-uchapupu hwekushanda kwezvigadzirwa zvevhavha.
Pakusarudza parameter, cherechedza kuti:
Kana iyo VALVE ICHIFANIRA KUSHANDISWA ZVINHU ZVINHU ZVINHU ZVINHU ZVINOFANIRA KUTI ZVINOFANIRA KUTSVAGA: nzira yekushanda, yakawanda UYE zvishoma zvinoda kuyerera, kudonha kwemhepo kunowanzoitika, kudonha kwemhepo pakuvhara, hukuru UYE hushoma hwekupinda mukati mevhavha.
Maererano nekusarudzwa kwepamusoro kwevhavha yevhavha uye matanho, kusarudzwa kwakanaka uye kwakarurama kwevhavha kunofanirawo kuva nekunzwisisa kwakadzama kwechimiro chemukati chemhando dzakasiyana-siyana dzevhavha, kuitira kuti ugone kusarudza zvakasarudzwa valve kuita sarudzo yakarurama.
Iyo yekupedzisira kutonga kwepombi ndiyo valve. Mavharuvhu ekuvhura nekuvhara zvikamu anodzora kuyerera kwe media mupombi, chimiro chevhavha inoyerera chiteshi chinoita kuti vharafu ive nehumwe hunhu hwekuyerera, iyo inofanirwa kuverengerwa pakusarudza vharafu yakakodzera kuisirwa mupombi system.
Sarudza vharafu inofanira kutevera musimboti
1, kucheka-kubvisa uye kuvhurika svikiro nevharuvhu
Iyo inoyerera mugero ndeye yakatwasuka-kuburikidza nevhavhavha, kuyerera kupikisa kudiki, kazhinji kunosarudzwa seyakachekwa uye yakavhurika svikiro nevhavha. Kudzika vharafu yakavharwa (globe valve, plunger valve) nekuda kweiyo tortuous kuyerera nzira, kuyerera kwekudzivirira kwakakwira kupfuura mamwe mavharuvhu, saka mashoma akasarudzwa. Mavharuvhu akavharwa anogona kushandiswa uko kuyerera kwakanyanya kunobvumidzwa.
2, kudzora kuyerera kwemavharuvhu
Ivhavha iyo iri nyore kugadzirisa inowanzosarudzwa kudzora kuyerera. Mavharuvhu ekudzika achivhara (akadai SEGLOBE) ANOKOdzera CHINANGWA ICHI NOKUTI UYE HWECHIGARO HWAKAENDEANA NEKUSVIRWA KWEZVINHU. Rotary VALVES (PLUG, butterfly, BALL mavharuvhu) uye FLEXURE BODY VALVES (PINCH, DIAPHRAGM) ANOWANIKWAWO KUTI HUNOGONESA, asi ZVINOGARA CHETE muchikamu chidiki chevharuvhu DIAMETERS. Gedhi VALVE IS Idhisiki rakaumbwa gedhi kune denderedzwa chigaro chiteshi kuita transverse kufamba, iyo chete iri padyo nenzvimbo yakavharwa, inogona kudzora zvirinani kuyerera, saka kazhinji haishandiswe kuyerera kuyerera.
3. Valvha yekudzosera kumashure uye kutsausa
Ivhavha inogona kuva nematanho matatu kana anopfuura, zvichienderana nekudiwa kwekudzosera uye kutsauka. Plug nebhora mavharuvhu akanyatsokodzera chinangwa ichi, uye saka, mavharuvhu mazhinji anoshandiswa kudzosera kumashure uye kutsausa anosarudzwa seimwe yeaya mavharuvhu. Nekudaro, MUZVIMWE ZVIMWE ZVINHU, mamwe MATINJI EMAVIVE ZVINOGONA KUSHANDISWA SEZVINHU ZVINHU ZVINHU ZVINHU ZVINHU ZVINHU ZVINHU ZVINHU ZVINOTSAUSA, ZVINHU ZVINHU ZVINHU ZVINHU ZVIMWE kana ZVIMWE ZVIMWE ZVINOGONA Akanyatsobatanidzwa kune mumwe nemumwe.
4. Mavharuvhu epakati ane zvidimbu zvakaturikwa
Kana iyo yepakati ine yakaturikwa zvimedu, ** yakakodzera kushandiswa kwezvikamu zvekuvhara pamwe nekuvhara pamusoro peiyo inotsvedza vharafu nekupukuta chiito. Kana KUSVIRWA KWAKANYORA KUSVIRWA NEKUFAMBIRA KWECHIGARO, ZVINHU ZVINOGONA KUTEPIWA, SAKA VALVITI IYI INONYANYA KUNYANYA KUNYANYA KUCHENA MEDIA KUSENGA KUTI KUSIMWA KWEZVINHU ZVINOGONA KUTI ZVINHU ZVINENGE ZVICHIDZIDZWA. Mavharuvhu ebhora uye mavharuvhu epuragi anopukuta nzvimbo yekuisa chisimbiso panguva yekuvhura nekuvhara, saka akakodzera kushandiswa mune midhiya ine yakaturikwa zvimedu.
