Chii chinonzi Grooved Fittings & Couplings?

Grooved couplings inobviswa pombi yekubatanidza. Nokuda kwekugadzirwa kwayo, zvindori zvekuvhara zvakakosha uye zvisungo zvinotorwa. Iyo haidi welding uye inogona kushandiswa kuisa akasiyana siyana emhando dzepombi. Zvakanakira zvekubatana kwakadaro zvinosanganisira disassembly yavo, pamwe nekuvimbika kwakanyanya, dzimwe nguva kupfuudza zviratidzo zvakafanana zvewelded uye glued majoini.

Groove joints dzakagadzirwa kare kare. MuHondo Yenyika Yekutanga, vakashandiswa kuisa mapaipi ane musanganiswa unopisa, waishandiswa mumoto. Kubva ipapo, vakashandiswa mumhando dzakasiyana-siyana dzerunyararo apo hukama hwakavimbika uye hwemhando yepamusoro hunodiwa.

Paunenge uchiisa pombi, kunyanya kukoshesa kunobhadharwa kune zvibatanidza. Kusimba uye kuvimbika kweiyo sisitimu, kugona kutsungirira mitoro yepamusoro, uye kureruka kwekuzotevera kugadzirisa kunoenderana nazvo. Kwenguva yakareba, tambo dzekubatanidza uye welding dzakashandiswa senzira huru dzekuisa. Nhasi, ma grooved couplings - anodzikiswa mabhanhire ane chisimbiso collar - ari kuwana mukurumbira. Muviri weiyo clamp inogadzirwa ne ductile iron kana kabhoni simbi, uye iyo yekuisa inogadzirwa neinopisa inodzivirira rubber-based material.

Zvichienderana nemitoro, kubatanidzwa kunogadzirwa nesimbi yakakandwa, carbon steel nezvimwe zvinhu zvakafanana. Kubatana kunosanganisira maviri ehafu uye elastic polymer O-ring (cuff). Mapaipi ane grooves (grooves) akabatanidzwa mumutsara, akabatanidzwa kune akabatanidzwa, uye nzvimbo yekushandura yakafukidzwa ne-o-ring chisimbiso.

Mune yepakutanga vhezheni, ma grooves e groove couplings akachekwa nevacheki vekugaya. Yakanga iri nzira yakaoma uye isingaite. Mazuva ano, chigadzirwa chakakosha chinoshandiswa kugadzira grooves - roller groovers. Izvo zvakasiyana nenzira yekutyaira (manual kana hydraulic) uye muhupamhi hwemapombi avanokwanisa kushanda nawo. Munzvimbo dzemaindasitiri, michina yekugezera yakamira inoshandiswa, inodhura zvakanyanya kushandiswa mudzimba. Asi nokuda kwezvikamu zviduku zvebasa kana kuti basa rekugadzirisa nguva dzose, kushanda kwechigadzirwa chemaoko chakakwana.

Iyo chete drawback yemajoini e groove ndiyo mutengo wavo wakakwira, wakakwira kupfuura mamwe marudzi. Izvi ndizvo zvinotadzisa kushandiswa kwavo kwakapararira. Zvishandiso zvekugadzira pombi zvinodhura zvakare; inotakurika groovers inodhura makumi akati wandei ezviuru zveRubles. Asi kune mavhoriyamu madiki ebasa, unogona kuhaya chishandiso; rombo rakanaka, kugona basa negroover hakuna kunyanya kuoma.

Mhando dze groove fittings

Iyo nheyo ye grooved fittings inoshandiswa kuita mabasa akasiyana-siyana panguva yekuisa pombi. Kune marudzi akawanda ezvipfeko zvakadaro:

• kubatanidza - classic version yakagadzirirwa kubatanidza zvikamu zviviri zvepombi dzehupamhi hwakafanana;

• gokora - chinhu chinotenderera chepombi ine mupendero wakanyatsogadzirwa unobvumira kuiswa nyore kwechigadziko;

• mapulagi - zvikamu zvinokubvumira kuti uvhare kwenguva pfupi kana zvachose davi repombi kana kuti uone kubatanidzwa kwe groovelock ne thread;

• concentric adapters - kukubvumira kuti ubatanidze pombi yediki dhayamita ine threaded fixation;

• slip-on flange - inochengetedza shanduko ye groove system kune flange system;

• zvimwe zvigadziriso - mienzaniso yakawanda yakagadzirirwa kugadzira compact bends zvakananga pamubatanidzwa.

Kune akaomesesa uye anochinjika grooved couplings. Iwo ekutanga akawedzera simba kuenzaniswa ne weld. Flexible sarudzo dzinokutendera kuti utsivise zvidiki zvidhori zvakatsauka uye kumirisana nemutsara wekumanikidza uye kushushikana. Grooved fittings inoshandiswa pamapombi ane dhayamita ye25-300 mm, saka zviri nyore kusarudza mabhanhire emapaipi kune zvakasiyana-siyana zvezvinangwa. Paunenge uchitenga zvigadzirwa, zvinodikanwa kujekesa huwandu hwemadhayamita ekushanda ayo chigadzirwa chakagadzirirwa. Izvi zvichabatsira kuona kana imwe sarudzo yakakunakira iwe.
