Nhungamiro yeButterfly Valve Installation

Kuiswa kwechokwadi kweabutterfly valveyakakosha pakuita kwayo yekuisa chisimbiso uye hupenyu hwesevhisi. Gwaro iri rinodonongodza maitirwo ekuisa, kutariswa kwakakosha, uye rinoratidza mutsauko uripo pakati pemhando mbiri dzinozivikanwa: wafer-style uye.flanged butterfly mavharuvhu. Wafer-style mavharuvhu, ayo akaiswa pakati pemapipeline flanges maviri achishandisa stud mabhaudhi, ane maitiro akaomarara ekuisa. Kusiyana neizvi, mavharuvhu eshavishavi ane mapapiro anouya neakakosha maflange uye anosungirirwa zvakananga kumapaipi epapeline flange, zvichiita kuti basa rive nyore.

Mabhaudhi eflange evharuvhu yeshavishavi akarebesa. Kureba kwavo kunoverengerwa se: 2x flange ukobvu + vharafu gobvu + 2x nut ukobvu. Izvi zvinodaro nekuti vharuvhu yeshavishavi pachayo haina maflange. Kana mabhoti aya nemanuts zvikabviswa, mapaipi ari kumativi ose evhavha achakanganiswa uye haagoni kushanda zvakanaka.

Mavharuvhu akachinjika anoshandisa mabhaudhi mapfupi, ane hurefu hunotsanangurwa se 2x flange ukobvu + 2x ukobvu hwenzungu, kubatanidza maflange evharuvhu zvakananga kune ayo ari papombi. Kubatsira kwakakosha kweiyo dhizaini ndeyekuti inobvumira kuti rimwe divi ribviswe pasina kukanganisa kushanda kwepombi yakatarisana.

Ichi chinyorwa chichanyanya kusuma mirairo yekuisa yewafer butterfly mavharuvhu neTWS.

The wafer butterfly valve ine dhizaini yakapfava, yakabatana, uye isina kuremerwa ine zvikamu zvishoma. Inoshanda nekukurumidza 90 ° kutenderera, ichigonesa nyore pa/kudzima kudzora uye kupa yakanakisa kuyerera kwemutemo.

I. Mirayiridzo Asati Kuisa theWafer-Type Butterfly Valve

1. Kuiswa kusati kwatanga, pombi inofanira kucheneswa chero chinhu chekunze uchishandisa mweya wakadzvanywa uye wozocheneswa nemvura yakachena.
2. Nyatsoongorora kana kushandiswa kwevhavha kunoenderana nemaitiro ayo ekuita (tembiricha, kumanikidza).
3. Tarisa muvharo wevharuvhu uye chisimbiso pamusoro pemarara, uye bvisa nekukasika.
4. Mushure mekusunungura, valve inofanira kuiswa nokukurumidza. Usasunungure chero masikuru ekusungirira kana nzungu pavharuvhu zvisina tsarukano.
5. Ivharuvhu yeshavishavi yakatsaurirwa inofanira kushandiswa kugadzira mavharuvhu erudzi rweshavishavi.
6. Theyemagetsi butterfly valveinogona kuiswa pamapombi chero ipi zvayo, asi kuitira nyore kugadzirisa, zvinokurudzirwa kuti urege kuiisa kumusoro.
7. Paunenge uchiisa butterfly valve flange, zvakakosha kuve nechokwadi kuti chiso cheflange uye chisimbiso cherubha chakabatana, mabhoti anosimbiswa zvakaenzana, uye nzvimbo yekuisa chisimbiso inofanira kukwana zvakakwana. Kana mabhoti asina kusimbiswa zvakafanana, zvinogona kuita kuti rubber iwedzere uye jam disc, kana kusundira kurwisana ne disc, zvichiita kuti pave nekuputika pamadziro evhavha.

II.Kuiswa: Wafer Butterfly Valve

Kuti uve nechokwadi chekuvhara-isina chisimbiso uye yakachengeteka, yakavimbika mashandiro evhavhavhavhavhavha, tevera maitiro ekuisa pazasi.

1. Sezvinoratidzwa, isa vheji pakati pezviviri zvakagara zvakagadzikwa, kuve nechokwadi kuti maburi ebhoti akanyatsoenderana.

2. Isai zvinyoro-nyoro mapeya mana emabhaudhi uye nzungu mumakomba eflange, uye simbisa zvishoma nzungu kuti ugadzirise flatness yeflange;

3. Shandisa nzvimbo welding kuchengetedza flange kune pombi.

4. Bvisa vharafu;

5. Weld zvizere flange kune pombi.

6. Isa vharafu chete mushure mekunge musanganiswa welded watonhora. Ita shuwa kuti vharafu ine nzvimbo yakakwana yekufamba mukati meflange kudzivirira kukuvadzwa uye kuti vheji disc inogona kuvhurika kune imwe nhanho.

7. Gadzirisa nzvimbo yevhavha uye simbisa mapeji mana emabhoti (chenjerera kuti urege kuwedzera).

8. Vhura valve kuti uone kuti diski inogona kufamba zvakasununguka, uye zvishoma kuzarura disc.

9. Shandisa maitiro emuchinjikwa kuti usimbise makungu ose.

10. Simbisa zvakare kuti valve inogona kuvhura uye kuvhara zvakasununguka. Cherechedza: Ita shuwa kuti valve disc haina kubata pombi.

Kuti ive yakachengeteka, isina kuvuza-isina mashandiro ewafer butterfly mavharuvhu, tevedzera izvi misimboti:

• Bata Nekutarisira: Chengetedza vharafu zvakachengeteka uye dzivirira zvinokanganisa.
• Rongedza Zvakananga: Ita shuwa kurongeka kwakaringana kweflange kudzivirira kuvuza.
• Usabvisa: Kana yangoiswa, vharuvhu haifanirwe kubviswa mumunda.
• Isa Permanent Supports: Chengetedza vharafu nezvitsigiro zvinofanirwa kuramba zviripo.

TWSinopa zvemhando yepamusoro mavharuvhu eshavishavi uye nemhinduro dzakakwana dzevharafu yegedhi, cheki vharafu,uyemavharuvhu ekuburitsa mweya. Bata nesu pane zvese zvaunoda valve.
