Pneumatic ball valve is evolved from globe valve. It has the same 90-degree rotating lift action, except that the cock body is a sphere with a circular through hole or channel passing through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90 degrees, spherical surfaces should appear at the inlet and outlet, thereby cutting off the flow. The pneumatic ball valve uses a pneumatic actuator, which only needs to rotate the air source 90 degrees to securely close a small rotational torque. The valve's perfectly equal cavities provide a straight flow path with little resistance to the medium. Pneumatic ball valves are generally considered a good choice for direct opening and closing, but recent developments have designed ball valves to throttle and control flow. The main feature of pneumatic ball valve is compact structure, convenient operation and maintenance, suitable for water, solvent, acid, natural gas and other general operating media and oxygen, hydrogen peroxide and other harsh operations and labor-saving operation, because the ball is supported by the upper and lower bearings, reducing friction and reducing imports Excessive sealing load due to huge sealing load due to pressure propulsion. eliminate.

Lub pneumatic pob valve muaj kev ruaj ntseg sealing muaj nuj nqi. Lub rooj zaum stainless hlau valve yog embedded nrog PTFE ib leeg -pob ntseg sealing nplhaib. Qhov kawg ntawm lub rooj zaum hlau valve kom ntseeg tau tias lub nplhaib sealing muaj txaus ua ntej -tightening force thiab yog nruab nrog lub caij nplooj ntoos hlav nro. Lub valve nto hnav tawm thaum siv, thiab lub valve tseem ua kom muaj kev sib khi zoo thaum lub caij nplooj ntoos hlav ua haujlwm. Cov qauv hluav taws kub tsis zoo, lub nplhaib foob hluav taws kub hnyiab tau nruab nrab ntawm lub pob lub cev thiab lub rooj zaum ntawm lub pneumatic tsau pob valve los tiv thaiv lub nplhaib PTFE sealing los ntawm kev kub hnyiab vim kub kub lossis hluav taws kub. Nyob rau lub sijhawm no, lub valve lub rooj sib khi lub nplhaib yog nrawm nrawm tawm tsam tus kheej nyob rau hauv cov nyhuv ntawm lub caij nplooj ntoos hlav quab yuam, kom lub foob raug tsim ntawm cov hlau, uas muaj qee yam kev sib khi. Kev ntsuas hluav taws kub ua tau raws li qhov yuav tsum tau ua ntawm AP16FA thiab API607 specifications. Kev ua haujlwm siab ua haujlwm, thaum lub siab ntawm qhov nruab nrab nyob rau hauv lub valve kab noj hniav nce txawv txav thiab tshaj qhov ua ntej- zawm quab yuam ntawm lub caij nplooj ntoos hlav, lub rooj zaum valve tau thim rov qab los ntawm tus kheej kom ua tiav cov txiaj ntsig ntawm kev ua haujlwm siab, thiab lub valve lub rooj zaum siab yuav rov pib dua tom qab tso tawm. Hauv cov raj xa dej, lub cev sab sauv thiab sab hauv lub cev muaj lub qhov dej ntws tawm, thiab xyuas seb lub rooj zaum valve puas tawm. Thaum lub sijhawm ua haujlwm, yog tias lub valve qhib tag nrho lossis kaw tag nrho, lub siab nyob rau hauv cov kab noj hniav yog: nws tuaj yeem raug tshem tawm ncaj qha thiab cov ntim tuaj yeem hloov tau. Tshem tawm cov dej khaws cia rau hauv cov kab noj hniav tseem ceeb kom txo tau cov kab mob ntawm lub valve los ntawm qhov nruab nrab.
Pneumatic tsau pob valve siv lub rooj zaum nruj sealing system tsim. Yog tias lub foob raug puas los yog tsis tuaj yeem kaw thaum muaj xwm txheej ceev, siv lub kaw lus pabcuam rau kev sib khi. Lub sealing nto tuaj yeem kho sai sai los ntawm kev txhaj tshuaj sealant rau ntawm qhov chaw. Yog hais tias qhov nruab nrab conveying yog qias neeg los yog cov ntsiab lus particle tsawg, lub sealing nto kuj tuaj yeem raug ntxuav los ntawm kev txhaj tshuaj los yog roj nplua nyeem los tiv thaiv lub sealing nto thiab xyuas kom ruaj khov. Pneumatic tsau pob li qub yog dav siv nyob rau hauv kev txiav los yog ncig ntawm cov raj xa dej tawm xws li zaub mov, tshuaj, roj av, tshuaj lom neeg kev lag luam, roj av, hlau, kev tiv thaiv ib puag ncig, thiab papermaking.
