Kuburikidza nekuunzwa kwezvinhu zvakasvibirira zvinodiwa, dhizaini zvinodiwa, kugadzira zvinodiwa, kuita zvinodiwa, nzira dzekuyedza, system application zvinodiwa, uye hukama pakati pekumanikidza uye tembiricha mune yepasirese epurasitiki valve chigadzirwa uye bvunzo nzira zviyero, unogona kunzwisisa kuiswa chisimbiso kunodiwa epurasitiki. mavharuvhu Basic quality control zvinodiwa senge bvunzo, torque bvunzo uye kuneta simba bvunzo. Muchimiro chetafura, zvinodikanwa zvekuisa chisimbiso chechigaro, bvunzo yekuisa chisimbiso chevharuvhu, bvunzo yesimba revhavha, bvunzo yenguva refu, kuyedza simba rekuneta uye torque yekushandisa inodiwa pakuita zvinodiwa zvezvigadzirwa zvepurasitiki valve zvinopfupikiswa. Kuburikidza nenhaurirano yezvinetso zvakati kuti mumitemo yenyika yose, vagadziri nevashandisi vemavharuvhu epurasitiki vanomutsa kunetseka.

Sezvo chikamu chepombi yepurasitiki mumvura inopisa uye inotonhora uye kushandiswa kweinjiniya yepombi pombi inoramba ichiwedzera, kutonga kwemhando yemavharuvhu epurasitiki mumapombi epurasitiki ari kuwedzera kukosha.

Nekuda kwezvakanaka zvehuremu huremu, kusagadzikana kwecorrosion, kusashambadza kwechiyero, kubatana kwakabatana nemapombi epurasitiki, uye hupenyu hurefu hwebasa remavharuvhu epurasitiki, mavharuvhu epurasitiki anoshandiswa mukugovera mvura (kunyanya mvura inopisa uye kudziyisa) uye mamwe madhiri emuindasitiri. Mune pombi system, mabhenefiti ayo ekushandisa haaenzaniswi nemamwe mavharuvhu. Parizvino, mukugadzirwa uye kushandiswa kwemavharuvhu epurasitiki epamba, hapana nzira yakavimbika yekuadzora, zvichikonzera kusaenzana kwemhando yezvigadzirwa zvemavharuvhu epurasitiki yekugovera mvura uye mamwe madhiri emumaindasitiri, zvichikonzera kuvharika uye kudonha kwakakomba mumainjiniya ekushandisa. Yakagadzira chirevo chekuti mavharuvhu epurasitiki haagone kushandiswa, zvichikanganisa kukura kwese kwekushandisa pombi yepurasitiki. mipimo yenyika yangu yemavharuvhu epurasitiki ari mukugadzirwa, uye zviyero zvechigadzirwa chavo uye nzira dzemaitiro zvinogadzirwa zvinoenderana nezvinodiwa nenyika dzese.

Munyika yose, marudzi epurasitiki mavharuvhu anonyanya kusanganisira bhora mavharuvhu, butterfly mavharuvhu, cheki mavharuvhu, diaphragm mavharuvhu, uye globe mavharuvhu. Mafomu ekuumbwa anonyanya kusanganisira maviri-nzira, matatu-nzira uye akawanda-nzira mavharuvhu. Izvo zvigadzirwa zvinonyanya ABS,PVC-U, PVC-C, PB, PE,PPuye PVDF etc.

Mumitemo yepasi rose yezvigadzirwa zvemavharuvhu epurasitiki, chekutanga chinodiwa zvinhu zvakabikwa zvinoshandiswa mukugadzira mavharuvhu. Mugadziri wezvakagadzirwa anofanirwa kunge aine inokambaira yekutadza curve inosangana nezviyero zvepurasitiki pombi zvigadzirwa. Panguva imwecheteyo, bvunzo yekuisa chisimbiso, bvunzo yemuviri wevhavha, uye yakazara Iyo yenguva refu yekuita bvunzo, kuneta simba kuyedza uye kushanda torque yevhavha zvese zvakatemwa, uye hupenyu hwekugadzira sevhisi yevhavha yepurasitiki inoshandiswa pakufambisa kwemaindasitiri. mvura inopiwa kuva 25 years.

Main tekinoroji zvinodiwa zvepasi rose zviyero

1 Raw zvinhu zvinodiwa

Zvinhu zvemuviri wevharuvhu, bhoneti uye bhoneti zvinofanirwa kusarudzwa zvinoenderana ne ISO 15493:2003 "Industrial epurasitiki pombi masisitimu-ABS, PVC-U uye PVC-C-Pipe uye yakakodzera sisitimu yakatarwa-Chikamu 1: Metric akatevedzana" uye ISO. 15494: 2003 “Industrial Plastic Piping Systems—PB, PE, uyePP-Pipe uye FittingZvido zveSistimu-Chikamu 1: Metric Series.

2 Zvido zvekugadzira

a) Kana vharuvhu iine tsinhiro imwe chete inotakura nzira, inofanira kuiswa museve kunze kwemuviri wevharuvhu. Ivhavha ine symmetrical dhizaini inofanirwa kuve yakakodzera nzira mbiri yekuyerera kwemvura uye kuparadzaniswa.

b) Chikamu chekuisa chisimbiso chinofambiswa nevhavha hunde kuvhura uye kuvhara vharafu. Inofanirwa kuiswa kumagumo kana chero chinzvimbo chepakati nekukweshana kana actuators, uye iyo fluid pressure haigone kuchinja chinzvimbo chayo.

c) Zvinoenderana neEN736-3, iyo shoma kuburikidza negomba revhavhavhavha rinofanirwa kusangana nemapoinzi maviri anotevera:

- Kune chero aperture iyo svikiro inotenderera pavhavha, haifaniri kunge iri pasi pe90% yeDN kukosha kwevhavha;

- Kuvharuvhu ine chimiro chinoda kuderedza dhayamita yepakati painoyerera, mugadziri anofanira kutaura hushoma hwayo kuburikidza neburi.

d) Chisimbiso pakati pehunde yevharuvhu uye muviri wevharuvhu unofanirwa kutevedzera EN736-3.

e) Mukutaura kwekupfekedzwa kwekuvhara kwevhavha, kugadzirwa kwevhavha kunofanira kufunga nezvehupenyu hwebasa rezvikamu zvakasakara, kana kuti mugadziri anofanira kuratidza mumirayiridzo yekushanda kurudziro yekutsiva iyo valve yose.

f) Muyero unoshanda wekuyerera weese mavharuvhu ekushandisa anofanirwa kusvika 3m/s.

g) Inoonekwa kubva kumusoro kwevhavha, mubato kana ruoko rwevharuvhu inofanira kuvhara vharafu munzira yewachi.

3 Kugadzira zvinodiwa

a) Zvimiro zvezvakatengwa zvigadzirwa zvinofanirwa kuenderana nemirairo yemugadziri uye kusangana nezvinodiwa zvechigadzirwa.

b) Muviri wevharuvhu unofanirwa kucherechedzwa nekodhi yezvinhu zvakasvibirira, dhayamita DN, uye zita rekumanikidza PN.

c) Boka revharuvhu rinofanira kunyorwa zita remugadziri kana chiratidzo chemugadziri.

d) Muviri wevharuvhu unofanirwa kunyorwa nezuva rekugadzira kana kodhi.

e) Muviri wevharuvhu unofanirwa kumakwa nemakodhi enzvimbo dzakasiyana dzekugadzira dzemugadziri.

4 Zvido zvekushanda kwenguva pfupi

Iko kushanda kwenguva pfupi chinhu chekuongorora fekitori muyero yechigadzirwa. Inonyanya kushandiswa pakuedza kuvhara kwechigaro chevhavha uye muedzo wekuvhara muviri wevhavha. Inoshandiswa kutarisa kushanda kwekuvhara kwevhavha yepurasitiki. Zvinotarisirwa kuti vharafu yepurasitiki haifaniri kunge iine mukati mekuputika (kuvhara kwechigaro chevhavha). , Panofanira kunge pasina kubuda kwekunze (valve body leakage).

Muedzo wekuisa chisimbiso chechigaro chevharuvhu ndeyekusimbisa mashandiro evhavhavha isolation piping system; bvunzo yekuisa chisimbiso yemuviri wevharuvhu ndeyekutarisa kuvuza kwevhavha stem chisimbiso uye chisimbiso chega chega chekubatanidza chevhavha.

Nzira dzekubatanidza vharafu yepurasitiki kune piping system ndeye

Butt welding connection: iyo dhayamita yekunze yevhavha yekubatanidza chikamu yakaenzana nehupamhi hwekunze hwepombi, uye chiso chekupedzisira chechikamu chekubatanidza chevhavha chinopesana nechekupedzisira kwepombi ye welding;

Socket bonding connection: chikamu chekubatanidza chevhavha chiri muchimiro chechigadziko, chinosungirirwa kune pombi;

Electrofusion socket connection: chikamu chekubatanidza valve chiri muchimiro chesoketi ine tambo yemagetsi yekupisa yakaiswa padhayamita yemukati, uye ndeye electrofusion kubatana nepombi;

Socket hot-melt connection: chikamu chekubatanidza valve chiri muchimiro chechigadziko, uye chakabatanidzwa nepombi ne-hot-melt socket;

Socket bonding connection: Chikamu chekubatanidza chevhavha chiri muchimiro chechigadziko, icho chinosungirirwa uye chinogadziriswa nepombi;

Socket rubber sealing ring connection: Chikamu chekubatanidza chevhavha imhando ye socket ine mukati me rubber sealing ring, iyo yakasungirirwa uye yakabatanidzwa nepombi;

Kubatana kweFlange: Chikamu chekubatanidza chevhavha chiri muchimiro cheflange, iyo yakabatana neflange papombi;

Thread connection: chikamu chekubatanidza valve chiri mumhando yeshinda, iyo yakabatanidzwa neshinda papombi kana kufanira;

Live connection: Iyo valve yekubatanidza chikamu chiri muchimiro chehupenyu chinongedzo, icho chakabatana nemapombi kana mafittings.

Ivhavha inogona kuva nemhando dzakasiyana dzekubatanidza panguva imwe chete.

Ukama huri pakati pekushanda kumanikidza uye tembiricha

Sezvo tembiricha yekushandisa inowedzera, hupenyu hwebasa hwemavharuvhu epurasitiki huchapfupiswa. Kuti uchengetedze hupenyu hwakafanana hwebasa, zvakakosha kuderedza kushandiswa kwekushandisa.
