Prinsipyo na panagkimey na check valve, klasipikasyon tan panag-alwar ed pangipaalagey

Panon ya mankikimey so check valve

Saycheck valve et uusaren ed sistema na tubo, tan say manunan gagala to et say pangisebel ed ipawil na medium, say pabaliktad ya panag-ikot na pump tan say driver motor to, tan say pangipaway na medium ed container.

I-tsek iray balbula nayarin usaren met ed saray linya ya mangisusuplay na saray auxiliary system ya say presyon et nayarin ontagey nen say presyon na manunan sistema. Saray check valve et nayarin iyaplika ed saray tubo na nanduruman media unong ed nanduruman materyales.

Say check valve et niiyan ed tubo tan magmaliw ya sakey ed saray kabiangan na pluido na kompleton tubo. Say proseso na panlukas tan pansara na valve disc et apektado na transient flow state na sistema ya kawalaan to; diad kasunian, say pansara na valve disc et walay epekto to ed estado na iyaagus na pluido.

Klasipikasyon na check valve

1. I-swing check valve

Say disc na swing check valve et singa disc tan manpapaliber ed shaft na valve seat channel. Lapud say kanal ed balbula et streamlined, say flow resistance et mas melag nen say lift check valve. Matukoy iya parad abeban agos tan matalag ya pananguman ed agos. Balet, ag-itan matukoy parad pulsating flow, tan say sealing performance to et aliwan singa say lifting type.

Say swing check valve et naapag ed taloran klase: single-lobe type, double-lobe type tan multi-lobe type. Sarayan taloran porma et manunan naapag unong ed diametro na balbula.

2. Itagey so check valve

Sakey a check valve ya say valve disc et onkukurang ed bertikal a sentro na laman na balbula. Say lift check valve et nayarin i-install labat ed pabitay ya tubo, tan say bola et nayarin usaren parad valve disc ed high-pressure ya melag ya diametro na check valve. Say kurti na laman na balbula na lift check valve et pareho ed globe valve (nayarin usaren ya pareho ed globe valve), kanian mas baleg so fluid resistance coefficient to. Say istruktura to et mipara ed globe valve, tan say laman tan disc na valve et pareho ed globe valve.

3. Butterfly check valve

Sakey a check valve ya say disc et onliliber ed sakey a pin ed yurongan. Say disc check valve et simpli so istruktura to tan nayarin i-install labat ed horizontal pipeline, tan makapuy so performance na sealing to.

4. Pipeline check valve

Sakey a balbula ya say disc et onkukurang ed sentro na laman na balbula. Say pipeline check valve et balon balbula. Melag so sukat to, anlemew so belat to tan maong so teknolohiya tod panagproseso. Sakey iya ed saray direksion na iyaaligwas na check valve. Balet, say fluid resistance coefficient et mas baleg na daiset nen say swing check valve.

5. Compression check valve

Sayan klase na balbula et uusaren bilang boiler feed water tan steam cut-off valve, walay integrated function to ya lift check valve tan globe valve odino angle valve.

Niarum ni, wala ray pigaran check valve ya ag manepeg ya pangipuesto ed pump outlet, singa say foot valve, spring type, Y type, tan arum nira.
