Kulumikizana kowoneka bwino ndi thupi la valavu yokhala ndi malekezero onse awiri, ikugwirizana ndi ma flanges pa mapaipi, pobowoleza oyikidwa papaipi. Kulumikizana kowoneka bwino ndi mtundu womwe umagwiritsidwa ntchito kwambiri wa Valve. Ma flangex ali ndi convex (rf), ndege (ff), contvex ndi concvede (mf) ndi mfundo zina. Malinga ndi mawonekedwe a mgwirizano, amatha kugawidwa m'njira zotsatirazi:
(1) Mtundu wosalala: wa valavu yokhala ndi zovuta zochepa. Kukonza ndikosavuta;
(2) Mtundu wa Concove ndi Convex: Kukakamizidwa kwambiri, kumatha kugwiritsa ntchito gasiketi yolimba;
.
.
(5) Mtundu wa LED: Gasket ili ngati mawonekedwe a mandala, zopangidwa ndi chitsulo. Amagwiritsidwa ntchito ngati mavuvu othamanga kwambiri ndi maamba a 100kg / cm2, kapena kutentha kwambiri kwamaluwa;

Kulumikiza kolumikizidwa ndi njira yabwino yolumikizira ndipo nthawi zambiri imagwiritsidwa ntchito ma valves ang'onoang'ono. Thupi la valavu imakonzedwa molingana ndi ulusi wokhazikika, ndipo pali mitundu iwiri ya ulusi wamkati ndi ulusi wakunja. Zogwirizana ndi ulusi pa chitoliro. Kulumikiza kolunjika kumagawidwa m'mavuto awiri:
(1) Kusindikiza mwachindunji: ulusi wamkati ndi wakunja amasewera mwachindunji. Pofuna kuonetsetsa kuti cholumikizira sichimatulutsa, nthawi zambiri ndi mafuta otsogolera, hemp ndi PTFF ndi PTF ORD Idzadzaza lamba; Pakati pawo, lamba wa lamba wa PTFID amagwiritsidwa ntchito kwambiri. Nkhaniyi imatsutsana ndi kutukwana, mphamvu zabwino kwambiri kugwiritsidwa ntchito, pogwiritsa ntchito, popewa, zitha kuchotsedwa kwathunthu, chifukwa ndizabwino kwambiri kuposa mafuta otsogola, hemp.

Pali mitundu isanu ya ulusi womwe umagwiritsidwa ntchito kawirikawiri:
(1) ulusi wamba;
(2) Inch zofala ulusi;
(3) ulusi chipika chipika;
(4) ulusi wopindika wopindika;
(5) Zingwe za ku America.
Mawu oyamba ndi awa:
① International Standa228/18, Din259, ya ulusi wamkati komanso wakunja wofanana, Code G kapena PF (BSP.F);
② Chijeremani mu ISO7 / 1, Din29999, BS21, chifukwa cha mano akunja, mano amkati chofanana, code bsp.p / PSP / PS;
③ Britain Standa7 / 1, BS21, BS21, ulusi wamkati ndi wakunja wa TT kapena BSP.TR kapena RC;
④ American Standard AnsI B21, ulusi wamkati ndi wakunja ndi wakunja g (pf), rp), ° (PSS), BSP.F.P. Tr molunjika kutanthauza mano.
Pali mitundu isanu ya ulusi wa chitoliro mu United States: NPSC General Office Serving a Tortings, NPSC ya ulusi wowongoka, magetsi olunjika zosiyirira zolumikizira zoyenera ndi mtedza wotseka. Sichikhala ndi ulusi wosindikizidwa wosindikizidwa (n: American National Standard; P: chitoliro; T: Treper)

Cholumikizira ndi kusindikiza kwa malaya ndi chakuti nati ngati mtedza ukulimbikitsidwa, kotero kuti m'mphepete mwa msewu wakunja wa chitolirocho, ndipo chulu chakunja chakumanja chimatsekedwa mwamphamvu ndi cene wa Thupi limodzi mopanikizika, motero imatha kupewa kutaya. MongaMakunja a Custontation.Ubwino wa mawonekedwe amtunduwu ndi awa:
.
.
(3) Kodi mungasankhe zinthu zosiyanasiyana, zoyenera kupewa kuwonongeka;
(4) Kulondola kwa makina kulibe;
(5) zosavuta kukhazikitsa kumtunda.
5. Kulumikizana
Ndi njira yolumikizirana mwachangu yomwe imafuna ma bolts awiri okha ndipo ndi yoyenera mavavu otsika omwe nthawi zambiri amachotsedwa.
