Nung ing pamili ning paralan ning pamagkonekta king butterfly valve ampo ing pipeline o kagamitan ustu ya o ali, direktang makaapektu ya king probability ning pamagdalagan, pamag-drip, pamag-drip at pamag-leak ning pipeline valve. Deng karaniwan a paralan ning pamagkonekta kareng balbula ilapin deng: pamagkonekta king flange, pamagkonekta king wafer, pamagkonekta king butt welding, pamagkonekta king threaded, pamagkonekta king ferrule, pamagkonekta king clamp, pamagkonekta king sarili a pamagkonekta at aliwa pang paralan ning pamagkonekta.
A. Koneksyun ning flange
Ing koneksyun ning flange metung yangflanged butterfly valvekareng flanges keng adwa nang wakas ning valve body, na makatuglung kareng flanges keng pipeline, ampo maka-install la keng pipeline kapamilatan ning pamag-bolt kareng flanges. Ing flange connection ing peka gagamitan a paralan ning koneksyun kareng balbula. Deng flanges makadake la keng convex surface (RF), flat surface (FF), convex ampo concave surface (MF), atbp.
B. Wafer connection
Ing balbula makabili ya keng libutad da reng adwang flange, ampo ing katawan ning balbula ningwafer butterfly valvekeraklan atin yang positioning hole para mas madali ing pamag-install ampo pamag-position.
C. Solder connection
(1) Butt welding connection: Deng adwang wakas ning valve body miprosesu la keng butt welding grooves agpang keng butt welding requirements, na makayagpang kareng welding grooves ning pipeline, ampo maka-fix la keng pipeline kapamilatan ning welding.
(2) Socket welding connection: Deng adwang wakas ning valve body miprosesu la agpang kareng requirements ning socket welding, at makakonekta la keng pipeline kapamilatan ning socket welding.
D. Threaded connection
Deng threaded connections metung lang madaling paralan ning pamagkonekta at maralas lang gagamitan para kareng mangalating balbula. Ing katawan ning balbula miprosesu ya agpang keng balang pamantayan ning sinulad, at atin yang adwang klasing panlub a sinulad ampo panlual a sinulad. Katumbas ne ning sinulad keng pipa. Adwa lang uri deng threaded a koneksyun:
(1) Direct sealing: Ing kilub ampo kilwal a sinulad direktang maglarin keng pamagseal. Para makasiguradung e ya mag leak ing koneksyun, maralas yang mitmung lead oil, thread hemp ampo PTFE raw material tape; nung nukarin ing PTFE raw material tape ing maralas dang gagamitan; ining materyales ayni atin yang masanting a resistensya keng kaagnasan ampo masanting a sealing effect. Madali yang gamitan at ibili. Potang i-disassemble, malyari yang ilako uling e ya malagkit a pelikula, na mas masanting kesa keng lead oil ampo thread hemp.
(2) Indirect sealing: ing sikanan ning thread tightening mipapadala ya keng gasket pilatan da reng adwang planu, para ing gasket maglarin yang sealing role.
E. ferrule connection
Ing ferrule connection megawa ya keng bansa ku keng milabas a banua. Ing kayang prinsipyung koneksyun ampo pamag-seal yapin ing nung ing nut masipit ya, ing ferrule mipailalam ya keng pressure, inya ing gilid ning ferrule makagat ya keng kilwal a pader ning pipe, ampo ing kilwal a cone surface ning ferrule makasuglung ya keng joint lalam ning pressure. Ing kilub ning katawan malapit ya keng tapered a babo, inya sa't ing leakage malyari yang aiwasan. kalupa da reng balbula ning instrumentu. Deng advantage na niting paralan ning koneksyun ilapin deng:
(1) Malati ya sukad, magaan ya timbang, simple ya istruktura, madali yang i-disassemble ampo i-assemble;
(2) masikan a pwersa ning koneksyun, malawak a gamit, matas a pressure resistance (1000 kg/cm 2 ), matas a temperatura (650 ° C) ampo shock ampo vibration;
(3) Malyari lang pilinan deng miyayaliwang materyales, para keng anti-corrosion;
(4) E la matas deng requirements para keng machining accuracy;
(5) Manyaman ya para keng matas a lugal.
Ngeni, ing ferrule connection form megamit ya kareng mapilan a malating diametru a produktu ning balbula keng bansa ku.
F. Grooved connection
ini ing mabilis a paralan ning pamagkonekta, kailangan mung adwang bolt, ampoing grooved end butterfly valvemanyaman ya keng mababang presyurbalbula ning parulna maralas mibubulag. antimo reng sanitary valves.
G. Internal self-tightening connection
Deng eganaganang koneksyun a makatuki gagamit lang panlual a pwersa para i-offset ing pressure ning medium para akwa ing pamag-seal. Ing tutuki maglarawan ya keng self-tightening a koneksyun gamit ing medium pressure.
Ing sealing ring na maka-install ya keng kilub ning cone at gagawang metung a angle ing gilid na makayarap ya keng medium. Ing pressure ning medium mipapadala ya keng kilub ning cone at kaybat keng sealing ring. keng cone surface ning metung a angle, adwa lang component forces ing mipalyari, ing metung atin yang ing sentru ning linya ning katawan ning balbula parallel ya keng kilwal, at ing metung makadikit ya keng kilub ning pader ning katawan ning balbula. Ing tauling pwersa yapin ing self-tightening force. nung mas maragul ing medium pressure, mas maragul ing self-tightening force. Uli na niti, ing pormang koneksyun ayni masanting ya para kareng high pressure valves.
Nung ikumpara me keng flange connection, makatipid yang dakal a materyales ampo manpower, pero mangailangan ya namang preload, para gamitan yang masalese nung ali ya matas ing pressure keng valve. Deng balbula a gagawan gamit ing prinsipyu ning self-tightening sealing keraklan high-pressure lang balbula.
Dakal la reng paralan ning pamagkonekta kareng balbula, alimbawa, deng mapilan a malating balbula a e na kailangang ilako, mi-welding la kareng tubo; deng aliwang e metal a balbula makasuglung la kareng socket ampo aliwa pa. Deng gagamit valve dapat lang pakibatan agpang keng partikular a sitwasyun.
Kasurat:
(1) Deng eganaganang paralan ning pamagkonekta dapat lang tuki kareng katuglung a pamantayan at linawe la reng pamantayan bang aiwasan ing pami-install ning mepiling balbula.
(2) Keraklan, ing maragul a diametru ning pipeline ampo ing balbula makasuglung la kapamilatan ning flange, at ing malating diametrung pipeline ampo ing balbula makasuglung la kapamilatan ning sinulad.
