Emaphuzu Labalulekile Etincazelo Tekufakwa Kwevalve Yemaphayiphi

I. Kulungiselela ngaphambi kwekufakwa

1. Hlola imodeli yekucaciswa kwevalve, lizinga lekucindzeteleka, kanye nekukhonjwa kwesicondziso sekugeleza kucinisekisa kutsi ihlangabetana netidzingo tekuklama.

2. Hlola kuhlanteka kwemgodzi wemtimba wevalve bese ususa tintfo tekuvikela tekupakisha kanye netintfo tangephandle.

3. Butt kushisela emavalvu uxhumano kudingeka prefabricated nge grooves, kanye flange uxhumano emavalvu kudingeka uhlole bucotfo ebusweni kuvala.

II. Kulawula Indlela Yekufaka

1. I valve yemhlaba kanye .ivalvu yekuhlola yekuphakamisa lemilekumele ifakwe ngalokucinile ngendlela lekhonjiswe ngumcibisholo emzimbeni wevalve.

2. Ngekwesimiso, .valve yesicu lesingakhuphuki, luhlobo lwemanti lwevalvu levivane, kanye nemavalvu ebhola angafakwa kuto totimbili tindlela, kepha kufanele kunakwe kutsi kusebente kalula.

3. Emavalvu agezi / emoyeni adzinga kubeka indzawo yekusebenta kwe-actuator kanye nekunakekelwa.

III. Tincazelo tekufakwa kwekushelela

1. I valve yekushelela yesibumbu kufanele igcinwe ivulekile ngesigamu ngesikhatsi sekushelela kuvikela kujama lokubangelwa kugucuka lokushisako.

2. Sebentisa argon arc welding kwenta sisekelo, bese ulawula interlayer lokushisa hhayi kwedlula lokushisa rated valve.

3. Ngemuva kwekushisela, levalve kumele ihlolwe kutsi iyasebenta yini kucinisekisa kutsi iyavula futsi ivalwe ngendlela lejwayelekile.

IV. Emaphuzu Labalulekile Ekuxhumana Kweflange

1. Letindzawo tekuvala te-flange tihlala tihambisana, futsi kuphambuka lokukhulu lokuvumelekile akudluli 0.15% we-flange diameter yangaphandle.

2. I gasket kufanele ibekwe enkabeni, emabhawudi kufanele aciniswa symmetrically futsi alingana, kanye torque rated kufanele kufinyelelwe ngetikhatsi letintsatfu.

3. Emabhawudi lahlanganisa emavalvu lashisa kakhulu kufanele aciniswe kabili esimeni lesishisako.

V. Kulawula Lizinga

1. Kuhlolwa kwemandla kanye nekuhlolwa kwekuvala kuyadzingeka ngemuva kwekufakwa.

2. Uma kuhlantwa luhlelo, ivalve yekulawula, imitha yekugeleza kanye naletinye tintfo tekusebenta kufanele tidlulwe.

3. Gcwalisa irekhodi lekufakwa, kufaka ekhatsi idatha lebalulekile njengenombolo yesikhundla sevalve, umfutfo wekuhlola, i-torque yekusebenta, njll.

Caphela: Le valve akukafaneli isetjentiswe njengendzawo yekusekela liphayiphi. Emavalvu lamakhulu adzinga luhlaka lwekusekela lolwehlukile. Ngemuva kwekufakwa, le valve kumele ibe sesimeni lesivaliwe ngalokuphelele futsi ivikelwe kugwema kulimala kwekusebenta lokuphambukile.
