II.Engnge's a danglamna chu?
Wafer type butterfly valve leh lug type butterfly valve pahnih hian butterfly valve connection form a kawk a, structural length inang leh thil tum inang a nei a, mahse design, installation, application, cost leh thil dang dangah erawh danglamna lian tak a awm thung.
1. 1. A rilru a hah lutuk chuan a rilru a buai em em a.Ruangam siamDifferences te pawh a awm
Lug butterfly valve: Valve body tawp pahnih hi threaded lugs hmanga siam a ni a, chu chu valve fixing atan a tha zawk.
Wafer butterfly valve: Chu ai chuan threaded inserts a nei lo va, flange pahnih inkarah clamp a ni a, pipeline flange leh valve body kaltlangin bolt kal tlangin a siam that a ni. Chu chu, pipeline flange-a bolt-te pressure hmanga design a ni tihna a ni.
2. 2. A rilru a hah lutuk chuan a rilru a buai em em a.Installation a niProcess tih hi a ni.
Lug butterfly valve hi pipeline enkawl ngai emaw, tihchhiat fo ngai emaw tan a tha hle. Threaded insert hi pipeline system pumpui tichhe lovin install leh disassemble awlsam tak a ni. Butterfly valve chhuak chu pipeline tawp lamah dahin terminal valve atan hman theih a ni.
- Valve body-a pressure awm loh nan lugs te chu flange bolt te nen a inmil em tih enfiah tur.
- Leakage awm loh nan a tul hunah gasket material dik tak hmang la, a bik takin medium pressure system-ah chuan.
- Valve chhunga pressure inang tlang taka awm theih nan bolt te chu a rualin khauh takin khih rawh.
Wafer butterfly valve hi pipeline tawp pahnih inzawmkhawmna atan hmun a tlem zawkna hmunah a tha zawk a, mahse a inthen theih avangin terminal valve atan hman theih a ni lo.
- Flange compatibility (eg ANSI, DIN) enfiah la, sealing a awm theih nan.
- Machine body a deformation loh nan flange bolt te khauh lutuk loh tur.
- System-ah pipeline vibration tlem ber hmanga dah a ni a, a loose loh nan.
3. Sealing Mechanism hman dan tur.
Lug butterfly valve hian threaded connection leh safety bolt avang hian seal khauh zawk a pe a, leak free operation a tichiang a, fluid backflow a veng bawk.
Chutih rualin, wafer type butterfly valve hian sealing rintlak tak a neih theih nan flange pahnih inkara compression a rinchhan a, chuvangin misalignment leh leakage awm loh nan pipeline nena inmil vek tura dah a ngai a ni.
4. DN&PN
- Butterfly valve-a wafer hi DN600 aiin a te zawk tlangpui a, single flange butterfly valve hi diameter lian zawk atan hman theih a ni. A tlangpuiin pressure ≤ PN16 a nih chuan an tha hle.
-Lug butterfly valve hian diameter lian zawk a nei a, pressure level sang zawk, PN25 thleng a tuar thei a, a chhan chu lug butterfly valve dahna hi a him zawk a ni.
5. C. A rilru a hah lutuk chuan a rilru a buai em em aost
Lug butterfly valve leh wafer butterfly valve te hi a man tlawm dan a inang lo hle.
Wafer butterfly valve hi a man tlawm zawk tlangpui a, a chhan chu design awlsam zawk, processing awlsam zawk leh material mamawh tlem zawk a nih vang a ni.
Lug butterfly valve hian threading a mamawh avangin machining process hi a buaithlak hle.
III. C. A rilru a buai em em aonclusion tih a ni
Lug butterfly valve leh wafer butterfly valve pahnih hi fluid flow control nan hman a ni a, mahse heng pahnih inkarah hian design, installation, sealing, diameter, pressure rating leh cost-ah danglamna lian tak a awm a ni. Duhthlan hunah chuan mamawh bik a zirin a hriat theih a ni: tihchhiat leh enkawl fo a ngai a nih chuan beng chhuak chi thlan a tha a Space a tight a, cost a ngaihtuah chuan wafer on design hi a tha zawk. Heng danglamna te hi hriatthiamna hian valve inmil zawk thlan nan leh flow control tha leh rintlak tak i neih theih nan a pui thei che a ni.TWSquality sang tak neihna atana thawhpui rintlak mai a ni lobutterfly valve te pawh a awm, mahse technical accumulation thuk tak leh solution puitling tak tak a nei bawkgate valve te a awm bawk, check valve te a awm bawk, boruak chhuahna valve, etc. Fluid control hian eng ang pawhin mamawh mahse, professional leh complete one-stop valve support kan pe thei che a ni.
