Introduksyon na Butterfly Valve

Introduksiyon:

Sakey a balbula na kulibangbanget nanlapud pamilya na saray balbula ya tatawagen yabalbula ya quarter-turn. Diad operasyon, say balbula et sigpot ya lukas o sarado no say disc et ipawil na kakapat na liko. Say “butterfly” et sakey a metal ya disc ya akapeket ed sakey a baras. No akasara so balbula, say disc et ibalikas pian sigpot ton nasaraan so dalanan. No say balbula et sigpot lan lukas, say disc et ibalikas na kakapat na liko pian ngalngali anggapoy limitasyon ya onlabas so pluido. Say balbula et nayarin lukasan met ya kalkalna pian na-throttle so agos.

Wala ray nanduruman klase na butterfly valve, ya balang sakey et akaadapta parad nanduruman pressure tan nanduruman usar. Say zero-offset butterfly valve, ya manguusar na flexibility na goma, so walaan na sankaabebaan ya pressure rating. Say high-performance double offset butterfly valve, ya uusaren ed saray sisteman mas atagey so presyon to, et walad sentro na disc seat tan body seal (offset one), tan say sentro na bore (offset two). Saya so manggagawa na cam action legan na operasyon pian naala so yurongan ed paway na seal ya manresulta ed daiset a friction nen say ginawa ed zero offset design tan nabawasan so tendensia ton mansulong. Say balbula ya sankaabigan parad saray sisteman high-pressure et say triple offset butterfly valve. Diad sayan balbula say disc seat contact axis et aka-offset, ya onkikiwas pian ngalngali naekal so sliding contact ed baetan na disc tan seat. Diad kaso na triple offset valves say yurongan et gawad metal pian nayarin makinan pian nawalaan na bubble tight shut-off no onsabi ed disc.

Saray klase

1. Saray konsentrikon balbula na kulibangbang– sayan klase na balbula et walay malet ya goma ya yurongan ya walay metal ya disc.
2. Doble-eksentrikon balbula na kulibangbang(high-performance butterfly valves odino double-offset butterfly valves) – nanduruman klase na materyales so uusaren parad yurongan tan disc.
3. Triply-eccentric butterfly valves(triple-offset butterfly valves) – saray yurongan et balanglan laminated odino solidon metal ya desinyo na yurongan.

Wafer-style butterfly valves

Saywafer style butterfly valveet adesinyo pian napansiansia so seal sumpad bi-directional pressure differential pian naprebentaan so antokaman ya backflow ed saray sisteman adesinyo parad unidirectional ya agos. Nagawaan to iya panamegley na malet ya selyo; salanti, gasket, o-ring, precision machined, tan sakey a patatdang a lupa na balbula ed tagey tan leksab na balbula.

Lug-style butterfly valve

Saray balbula ya singa lugwalay sinulid ya insert ed duaran dapag na laman na balbula. Lapud saya et nayarin i-install iratan ed sakey a sistema ya manguusar na duaran set na bolts tan anggapoy nuts. Say balbula et niiyan ed baetan na duaran flange ya uusaren so nanduruman set na bolts parad kada flange. Sayan setup et mangiter na pankanawnawan nadiskonekta so balang dapag na sistema na tubo ya ag nadisturbo so sananey a dapag.

Say lug-style butterfly valve ya uusaren ed dead end service et kaslakan ya abeba so pressure rating to. Singa bilang, say lug-style butterfly valve ya akapeket ed baetan na duaran flange et walay 1,000 kPa (150 psi) ya pressure rating. Say parehon balbula ya akapeket ed sakey a flange, diad dead end service, et walaan na 520 kPa (75 psi) ya rating. Saray lugged valve et ag-onkulang ed saray kemikal tan solvent tan sarag dan sungdoan so temperatura ya anggad 200 °C, kanian sakey itan ya solusyon ya dakel so nausar to.

Usaren ed industriya

Diad industriya na parmasyutiko, kemikal, tan naakan, say butterfly valve et uusaren pian naandi so iyaagus na produkto (solido, likido, gas) ed loob na proseso. Saray balbula ya uusaren ed sarayan industriya et kaslakan ya gagawaen unong ed saray totontonen na cGMP (kaplesan ya maong ya gagawaen ed panaggawa). Saray butterfly valve et kaslakan ya onsasalat ed saray ball valve ed dakel ya industriya, lalo la ed petrolyo, lapud mas abeba so gastos tan mainomay ya i-install, balet saray tubo ya walay butterfly valve da et ag nayarin 'pigged' parad panaglinis.
