1. Valve lub cev cov ntaub ntawv

Lub cev valve yuav tsum tiv taus siab, corrosion, thiab mechanical stress. Cov ntaub ntawv uas muaj xws li:

A. Stainless hlau (303, 304, 316)

• Pros:High corrosion kuj, ruaj, tuav siab siab

• Cons:Ntau dua li cov yas

• Qhov zoo tshaj plaws rau:Kev siv tshuaj, kev kho mob, thiab zaub mov qib

B. Brass (C36000)

• Pros:Nqi-zoo, zoo machinability

• Cons:Yooj yim rau dezincification hauv cov kua dej txhoj puab heev

• Qhov zoo tshaj plaws rau:Cua, dej, thiab tsawg-corrosion ib puag ncig

C. Engineering Plastics (PPS, PEEK)

• Pros:Lub teeb yuag, tshuaj-resistant, hluav taws xob insulating

• Cons:Tsawg siab kam rau siab dua hlau

• Qhov zoo tshaj plaws rau:Tsawg-siab, corrosive media (piv txwv li, cov khoom siv hauv chav kuaj)

2. Cov khoom siv sealing

Cov ntsaws ruaj ruaj yuav tsum tiv thaiv cov xau thaum tiv thaiv hnav thiab tshuaj tua kab mob. Cov kev xaiv tseem ceeb:

A. Nitrile Roj Hmab (NBR)

• Pros:Zoo roj / roj kuj, nqi-zoo

• Cons:Degrades nyob rau hauv ozone thiab muaj zog acids

• Qhov zoo tshaj plaws rau:Hydraulic roj, cua, thiab dej

B. Fluorocarbon (Viton® / FKM)

• Pros:Cov tshuaj zoo heev / kub tsis kam (-20 ° C txog + 200 ° C)

• Cons:Pheej yig, tsis zoo-kub yooj yooj yim

• Qhov zoo tshaj plaws rau:Aggressive solvents, fuels, high-temperature applications

C. PTFE (Teflon®)

• Pros:Yuav luag chemically inert, tsis tshua muaj kev sib txhuam

• Cons:Harder sealing, nws yooj yim rau cov dej txias

• Qhov zoo tshaj plaws rau:Ultra-ntshiab los yog corrosive kua heev

D. EPDM

• Pros:Zoo rau dej / chav dej, ozone-resistant

• Cons:Swells nyob rau hauv cov kua roj av

• Qhov zoo tshaj plaws rau:Kev ua zaub mov, dej tshuab

3. Cov khoom siv solenoid coil

Coils tsim lub zog electromagnetic los ua kom lub valve. Cov ntsiab lus tseem ceeb:

A. Copper Hlau (Enameled/Magnet Wire)

• Txheem xaiv:High conductivity, nqi-zoo

• Kub txwv:Chav Kawm B (130 ° C) txog H (180 ° C)

B. Coil Bobbin (Plastic vs. Hlau)

• Yas (PBT, Nylon):Lub teeb, hluav taws xob insulating

• Hlau (Aluminium):Zoo dua tshav kub dissipation rau high-duty cycles

C. Encapsulation (Epoxy vs. Overmolding)

• Epoxy txheej:Tiv thaiv kev ya raws / kev vibration

• Overmolded coils:Ntau compact, zoo dua rau qhov chaw ntxhua khaub ncaws
