Butterfly Valve Hramthawknak

Theihternak:

A butterfly valvetiah auhmi valve chungkhar chungin a siquarter-turn valves. Riantuannak ah, disc cu cheu li cheu khat an mer tikah valve cu a tling tein aa on asiloah a khar. “Butterfly” cu fung cung ah hrenmi thir disc a si. Valve an khar tikah, disc cu a kalnak lam kha a phih dih nakhnga an mer. Valve cu a tling tein a on tikah, disc cu cheu li cheu khat aa mer i cu nih cun ti kha khamnak um loin a kal khawh. Valve cu throttle flow tuah khawhnak ding caah tlawmpal in on khawh a si.

Butterfly valve phunphun an um, pakhat cio cu aa dangmi hneknak le hmannak aa dangmi caah remhmi an si. Zero-offset butterfly valve, cu nih cun rubber a nemnak a hman, cu nih cun a niam bikmi hneknak a ngei. Tlawmpal a sang deuhmi hneknak system ah hmanmi a ttha ngaimi double offset butterfly valve cu disc tthutnak le pum kharnak (offset pakhat) le bore laifang line (offset pahnih) in aa hlat. Mah nih hin riantuan lio ah cam cawlcanghnak a ser i tthutdan kha kharnak chungin a chuahter i cu nih cun zero offset design ah sermi nakin a tlawm deuhmi hnahnawhnak a chuahter i a rawkralnak a zorter. A ttha bikmi valve cu high-pressure system caah a ttha bikmi cu triple offset butterfly valve a si. Hi valve ah hin disc tthutnak pehtlaihnak axis cu aa tthen, cu nih cun disc le tthutnak karlak ah a tlikmi pehtlaihnak kha a hloh dih. Triple offset valve kongah cun tthutnak cu thir in sermi a si caah disc he aa tongh tikah bubble tight shut-off hmuh khawhnak ding caah seh in ser khawh a si.

Phun hna

1. Concentric butterfly valves– hi bantuk valve nih hin thir disc he a fekmi rubber tthutnak a ngei.
2. Aa dangmi hlinghro valve pahnih(a ttha ngaimi butterfly valve asiloah double-offset butterfly valve) – tthutdan le disc caah thilri phun dangdang hman a si.
3. Triply-eccentric butterfly valves(triple-offset butterfly valves) – tthutdan pawl cu a tlongmi asiloah thir fekmi tthutdan suaimi an si.

Wafer-style butterfly valves

Mah cuwafer phun butterfly valvecu lam khatlei in a kalmi luannak caah sermi system ah hnulei luannak a um lonak hnga lam pahnih in a kalmi hneknak thleidannak kha khar peng awkah sermi a si. Mah cu a fekmi hrennak in a tuah khawh; cu cu, gasket, o-ring, a dikthliar in sermi, le valve cunglei le tanglei lei ah a tlarimi valve hmai.

Lug-style butterfly valve

Lug-style valvesvalve pum kap hnih ah hri aa tthenmi an ngei. Mah nih cun bolt phun hnih le nut um loin system chungah chiah khawhnak a pek hna. Valve cu flange pahnih karlak ah flange pakhat cio caah a dang tein bolt set hmangin chiah a si. Hi timhtuahnak nih hin pipe system khatlei khatlei kha a dang lei kha buaiter loin tthen khawhnak nawl a pek.

A donghnak riantuannak ah hmanmi lug-style butterfly valve cu a tlangpi in a niam deuhmi hneknak tahfung a ngei. Tahchunhnak ah, flange pahnih karlak ah chiahmi lug-style butterfly valve cu 1,000 kPa (150 psi) pressure rating a ngei. Cu valve cu flange pakhat he bunhmi a si, a donghnak riantuannak ah, 520 kPa (75 psi) tlukruannak a ngei. Lugged valves cu chemical le solvents pawl kha an doh tuk hna i 200 °C tiang lumnak kha an tuar khawh, cu nih cun a phunphun in hman khawhmi a siter.

Chawlehthalnak ah hman

Sii, chemical le rawl sernak ah, butterfly valve cu thil kalning (a fekmi, ti, thli) a luannak kha kham awkah hman a si. Hi riantuannak ah hmanmi valve pawl cu cGMP lamhruainak (atu lio thil sernak phunglam ttha) ningin sermi an si tawn. Butterfly valve nih a tlangpi in chawlehnak tampi ah ball valve kha a thlen, a bik in petroleum ah, a man a fawi deuh caah le chiah a fawi caah, asinain butterfly valve aa telmi pipeline pawl cu thianhnak caah 'pigged' khawh an si lo.
