Ubwoko bw'insanganyamatsiko no gutahura

Urudodo rwa NPT ni urwego rwabanyamerika 60 ° taper pipe.Inzira yo kubara umurongo wurudodo ni: Inzira ya diameter yo hagati yurudodo ni: D2 = d2 = D-0.8XP Inzira yinzira yinzira ni: D1 = d1 = D-1.6XPUburyo bukwiye bwurudodo ni igabanijwemo cone-post ikwiranye cyangwa cone-cone ikwiranye.Uburebure bwurudodo L nigiteranyo cyuburebure nyabwo bwuburebure buringaniye buringaniye butarenze intera yerekana + amafaranga yo guterana.Nyuma yo gutunganya urudodo, mugihe ibicuruzwa byarangiye birangiye, ikimenyetso cyerekana umurongo kigomba gushyirwaho ikimenyetso isura yanyuma yurudodo cyangwa ahandi hantu heza ijisho, nka: 4-8NPT-LHTGufunga iyi nsanganyamatsiko birangizwa nuburyo bwo gufunga hagati yurudodo.Iyo habaye impaka zo kugenzura umugozi wacometse kumpeta, ikigo cyipimisha cyumwuga kizatsinda.

Umuyoboro wa peteroli ya LP

ubugenzuziLP ya peteroli ya peteroli;Bisa na NPT vertebral umuyoboro wurudodo hamwe nu mugozi uringaniye Inguni ya 60 ° na taper ya 1:16.Itandukaniro riri hagati yaryo na NPT vertebral umuyoboro wumugozi ni uko uburebure bwurudodo rwa LP rwibisobanuro bimwe biri munsi yubwa NPT, uburebure bwa LP ni 0.073P, mugihe uburebure bwurudodo rwa NPT ari 0.033P, ni ukuvuga inama y'urudodo rwa LP iraryoshye cyane kurenza urudodo rwa NPT.Kandi umugozi wa LP ufite ihagarikwa, urashobora kurinda neza urudodo kwangirika, Ikidodo cya LP gifunzwe numurongo w amenyo, kubwibyo gutunganya neza birenze ibyo NPT isabwa, kandi uburebure bukomeye bwurudodo rwa LP ni burebure kuruta NPT , byongera ingorane zo gutunganya.
