Deng specifications ampo models ning maka-install a valve e la makayagpang kareng requirements ning design.
Alimbawa, ing nominal pressure ning balbula mas ditak ya kesa keng system test pressure; ing gate valve para keng feed water branch pipe nung ing pipe diameter mas ditak ya o katumbas ne ning 50mm; ing dry ampo risers para keng mapaling danum; at ing fire pump suction pipe gamitan nebalbula ning parul.
Ing bunga: makaapektu ya keng normal a pamagbukas ampo pamagsara ning balbula ampo i-adjust ing resistensya, pressure ampo aliwa pang gagawan. Agyang ing sangkan ning operasyun ning sistema, ing pangasira ning balbula mapilitan yang ayusan.
Sukat: Maging pamilyar ka keng application scope da reng miyayaliwang valves, ampo pilinan mo reng specifications ampo models da reng valves agpang keng design requirements. Ing nominal a pressure ning balbula dapat yang makatupad kareng requirements ning system test pressure. Agpang keng construction code: ing stop valve dapat yang gamitan nung ing diameter ning pipe mas ditak ya o katumbas ne ning 50mm; ing gate valve dapat yang gamitan nung ing diameter ning pipe maygit yang 50mm. Ing mapaling danum a magpainit, ing vertical control valve dapat gamitan ya ing gate valve, ing fire water pump suction pipe e ya dapat gamitan ing butterfly valve.

Deng peka-maulagang materyales, kagamitan ampo produktung gagamitan keng konstruksyun ala lang technical quality appraisal documents o product certificates na makatupad keng kasalukuyan a national o ministerial standards.
Ing bunga: e kwalipikado ing kalidad ning proyektu, posibling aksidenti, e malyaring i-deliver keng oras, kailangan yang gawan pasibayu at ayusan; magresulta keng delay ning construction ampo pamagdakal ning labor ampo material input.
Sukat: Deng manimunang materyales, kagamitan ampo produktung gagamitan keng suplay ning danum ampo proyektung pamangisnawa dapat atin lang technical quality appraisal documents o sertipiku ning produktu a makayagpang kareng kasalukuyan a standards a pepalwal ning estado o ning Ministry; samantalang, ing lagyu ning produktu, modelu, specification, national quality standard code, petsa ning pamagdeliver, lagyu ning manufacturer ampo ing lugal, inspection certificate o code ing dapat ipabalu.

Balbula makabaliktad
Ing bunga: check valve, throttle valve, pressure reducing valve, check valve ampo reng aliwang valve atin lang direksyun, nung maka-install yang makabaliktad, ing throttle valve makaapektu ya keng service effect ampo keng bie; ing pressure reducing valve e ya gagana, ing check valve magdalang panganib.
sukad: pangkabilugan a balbula, a maki tanda ning direksyun keng katawan ning balbula; nung ali, dapat yang akilala agpang keng prinsipyu ning obra ning balbula. Ing valve cavity ning stop valve asymmetric ya, ing fluid dapat yang dumalan keng valve mouth manibat lalam angga babo, para ing fluid resistance malati ya (determined keng shape), open labor saving (uli ning medium pressure up), isara ing medium ali ya pressure ing packing, madaling maintenance. ini ing sangkan nung bakit e ya malyaring i-settle ing stop valve.

Ing balbula e ya gagawang heat insulation ampo cooling measures
Lakdanan: deng mapilan a balbula kailangan atin lang panlual a proteksyun, ini ing thermal insulation ampo cold protection. Ing thermal insulation steam pipeline misan midagdag ya keng insulation layer. Nanu ya ing klasing balbula na dapat maka-insulate o marimla, agpang keng kailangan ning pamaglalang. Ing prinsipyu, nung nukarin ing medium keng valve babawasan na ing temperatura masyadu, makaapektu ya keng production efficiency o magfreeze ya ing valve, kailangan ne ing insulation, pati na ing heat tracing; nung nukarin ing balbula makabuklat ya, e ya masanting keng pamaglalang o maging sangkan ning yelo ampo aliwa pang e masanting a bage, kailangan yang manatili keng dimla. Deng materyales para keng thermal insulation ilapin deng asbestos, slag cotton, glass wool, perlite, diatom soil, vermiculite; deng materyales a proteksyun keng dimla kayabe la reng cork, perlite, foam, plastic, atbp.

Ing drain valve ali ya maka-install keng bypass
Sukat: deng mapilan a balbula, dagdag pa kareng kailangan a proteksyun, pero atin la namang bypass ampo instrumentu. Ing bypass maka-install ya para mas madali ing pamag-maintain keng water trap. Deng aliwang balbula, atin la namang maka-install a bypass. nung mag install yang bypass dependi ya keng kondisyun ning balbula, importansya ampo ing kailangan keng pamaglalang.

Ing filler ali ya regular a mibayu
sukad: inventory valve, atin filler ali ya masanting, atin ali consistent keng pamangamit media, na kailangan palitan ing filler.
Ing balbula makayarap ya kareng libu-libung uri ning miyayaliwang media, at ing filling letter parati yang mitmu kareng ordinaryung plate roots, pero nung gamitan ya, ing packing kailangan yang mibabagay keng medium.
Potang palitan me ing filler, pindutan meng pabilug at pabilug. Balang lap joint 45 degrees ya, ampo ing ring ampo ing ring joint 180 degrees la. Ing katas ning packing dapat yang ikonsidera ing silid para keng patuloy a pamag-press keng takpan, at ngeni, ing lalam nang dake ning takpan dapat atin yang karapatdapat a kalalam, na keraklan 10-20% ning kabilugan a kalalam ning packing chamber.
Bukud pa, ing Tianjin Tanggu Water Seal Valve Co., Ltd. metung yang technologically advanced a elastic seat valve a susuporta kareng negosyu, deng produktu ilapin deng elastic seat wafer butterfly valve,lug butterfly valve,double flange concentric butterfly valve, double flangeeccentric butterfly valve, balance valve,wafer dual plate check valve, Y-Strainer at aliwa pa. King Tianjin Tanggu Water Seal Valve Co., Ltd., pagmaragul mi ing pamamie ming mumunang klasing produktu na makatupad kareng pekamatas a pamantayan ning industria. Kareng kekaming dakal a uri da reng balbula ampo fittings, malyari kang magtiwala kekami na mamye kang perpektung solusyun para keng kekang sistema ning danum. Makipag ugnayan kekami ngeni para abalu mu ing tungkul kareng kekaming produktu ampo nung makananu dakang asaupan.
