Valve dahna tur taboo pali

1. Thlasik laiin sak laiin negative temperature-ah Hydrstatic test.

A rah chhuah: hydraulic test neih laiin tube chu a freeze nghal vat avangin tube chu a vawt ta a ni.

Thiltih dan: thlasik hman hmain hydraulic test neih tum la, pressure test zawhah tui puak tur chuan, a bik takin valve chhunga tui chu net-ah paih chhuah a ngai a, chuti lo chuan valve chu light rust, heavy frozen crack a ni. Project hi thlasik lai, indoor positive temperature hnuaiah kalpui tur a ni a, pressure test zawhah tui chu puak fai tur a ni.

2. Valve dah dan a dik lo.

Entirnan, check valve flow direction chu mark nen a inpersan a, stem chu hnuai lamah dah a ni a, horizontal-a dah check valve chu vertical-a dah a ni a, hmun hawn leh khar a awm lo va, valve thup stem chu inspection kawngkhar lam hawi lo a ni.

A rah chhuah: valve a chhiat avangin switch enkawl a harsa a, valve shaft hnuai lam hawiin tui a chhuak fo thin.

A tehna: strict takin valve installation instructions for installation angin, open rod gate valve chu valve stem elongation opening height vawng reng turin, butterfly valve fully consider the handle rotation space, valve rod chi hrang hrang chu horizontal position hnuaiah a awm thei lo, hnuai lam chu sawi loh. Valve thup chuan inspection kawngkhar chu valve hawn leh khar dan nena inmil turin a set mai bakah valve stem chu inspection kawngkhar lam hawiin a awm tur a ni.

3. Valve dahna specification leh model te hian design mamawh a tlin lo.

Entirnan, valve-a nominal pressure chu system test pressure aiin a tlem zawk a; pipe diameter 50mm aia tlem emaw, a tlukpui emaw a nih chuan feed water branch pipe atana gate valve; tui lum tihlumna atana dry leh risers te; leh fire pump suction pipe hian butterfly valve a hmang bawk.

A rah chhuah: valve hawn leh khar dan pangngai a nghawng a, resistance, pressure leh hnathawh dangte a siamrem bawk. System hnathawh tir pawh nise, valve chhiatna chu siamthat a ngai a ni.

Thiltih dan: Valve hrang hrangte hman dan tur hriat chian la, design mamawh angin valve specification leh model te thlang rawh. Valve-a nominal pressure hian system test pressure-a thil mamawh a tlin tur a ni. Construction code angin: pipe diameter 50mm aia tlem emaw, a tlukpui emaw a nih chuan stop valve hman tur a ni; pipe diameter 50mm aia tam a nih chuan gate valve hman tur a ni. Tui lum vawt vawt, vertical control valve hman tur a ni a, gate valve hman tur a ni a, fire water pump suction pipe ah butterfly valve hman loh tur a ni.

4. Temperature sang takah valve dah dik loh.

A rah chhuah: leakage accident a thlen thei

Measures: high temperature valve 200°C aia sang, a chhan chu installation chu normal temperature-ah a awm a, normal hman hnuah temperature a sang a, bolt chu heat expansion a ni a, gap a tisang a, chuvangin tighten leh a ngai a, “hot tight” an ti a, operator-te chuan he hna hi ngaihven tur a ni, chuti lo chuan leak a awlsam hle.

Tianjin Tanggu Water Seal Valve Co., Ltd. hi technology lama hmasawn tak elastic seat valve supporting enterprise te a ni a, a thil siamte hi elastic seat a niwafer hnim hring valve a ni, lug hnim hring valve, .double flange concentric butterfly valve a awm bawk, double flange eccentric butterfly valve, a chhuahna tur hmun leh a hmanna tur hmun.balance valve a ni, wafer pahnih plate check valve, .Y-Strainer a nileh a dangte. Tianjin Tanggu Water Seal Valve Co., Ltd. ah hian industry standard sang ber nena inmil first-class product kan pe thei hi kan chhuang hle. Valve leh fitting hrang hrang kan neih avangin i tui system atana solution tha ber kan pe thei ang tih i ring thei ang.
