N'oge na-adịbeghị anya, ogbako Jinbin emechaala ọtụtụ iwu maka valvụ bọọlụ agbadoro nke ọma. Nkevalvụ bọọlụ agbadoro nke ọmanakweere ihe agbakwunyere welded Ọdịdị. A na-emepụta ahụ valvụ ahụ site na ịgbado ọkụ abụọ hemispheres. Ihe dị n'ime ime bụ bọọlụ nwere okirikiri site na oghere, nke ejikọtara na mpụga ihe na-eme ihe site na eriri valvụ. Mgbe a na-arụ ọrụ, ndịbọọlụ valvụ flangeA na-akwagharị steepụ ka ọ tụgharịa site na aka, igbe gear ma ọ bụ ngwaọrụ eletrik / pneumatic.

Uru nke iji ụlọ ọrụ valvụ bọọlụ welded zuru oke:

1. Nhazi a pụrụ ịdabere na ya na arụmọrụ akara siri ike

Usoro ịgbado ọkụ n'ozuzu na-ewepụ ihe egwu dị egwu nke njikọ flange ọdịnala ma dabara adaba maka ọnọdụ ọrụ siri ike dị ka nrụgide dị elu, ọkụ na mgbawa (dịka ọmụmaatụ, nrụgide nke pipeline gas nwere ike iru 10MPa). Ihe mkpuchi mkpuchi na-eyi na-eguzogide ọgwụ ma nwee ndụ ọrụ karịa afọ 10, na-ebelata ugboro ole mmezi.

2. Nkwụsi ike dị ala na ụzọ zuru ezu

Spherical site na oghere kwekọrọ na dayameta dị n'ime nke ọkpọkọ ahụ, na nkwụsi ike nke usoro ahụ bụ naanị 1/10 nke ọkpọkọ nke otu ogologo ahụ, na-ebelata ike oriri. Ọ kachasị mma maka njem njem dị elu (dịka ọmụmaatụ, dayameta ọkpọkọ nke pipeline mmanụ nwere ike iru 1200mm).

3. Na-eguzogide corrosion na ime mgbanwe na gburugburu ebe ọjọọ

A na-eji igwe anaghị agba nchara ma ọ bụ carbon steel mkpuchi corrosion (dị ka epoxy resin), nke nwere ike iguzogide mmebi ala na oke mmiri mmiri, ma dabara adaba maka ọnọdụ dị mgbagwoju anya dị ka n'okpuru ala na n'okpuru mmiri.

4. Ọ dị mfe ịrụ ọrụ na ọnụ ahịa mmezi dị ala

Ịtụgharị 90° nwere ike mechaa oghere na mmechi. Ejikọtara ya na sistemụ njikwa akpaka, enwere ike nweta njikwa anya. Ihe owuwu welded na-ebelata akụkụ ndị na-akpụ akpụ, nwee obere ọdịda, yana enwere ike ịgbatị usoro mmezi ahụ ihe karịrị afọ ise.

Ihe ndapụta ngwa ngwa nke valvụ bọọlụ moto agbadoro nke ọma:

Usoro pipeline dị anya

Mbufe gas eke - eji n'ọdụ ụgbọ mmiri nke ikuku gas dị n'akụkụ mmiri (dịka West-East Gas Pipeline) na pipeline nnyefe gas, ọ nwere ike iguzogide nrụgide dị elu ma hụ na akara ogologo oge iji gbochie ihe mberede nchekwa nke ikuku gas na-akpata.

Ụgbọ njem mmanụ a nụchara anụcha / mmanụ a nụchara anụcha - Ịchịkwa ụzọ na-erugharị nke onye na-ahụ maka ihe na-agafe na pipeline mmanụ , nhazi zuru oke na-ebelata njide mmanụ na nrụgide nrụgide, ma na-eme ka ọrụ njem dịkwuo mma.

2. Obodo gas na netwọk ọkpọkọ kpo oku

A na-eli ya ma tinye ya n'ime ọkpọkọ gas nke obodo mepere emepe iji dozie nhazi ala na mgbanwe mgbanwe okpomọkụ ma belata ihe ize ndụ nke ntanye. Jikwaa mmiri ọkụ na-erugharị na sistemu kpo oku Central, ma nagide nrụgide dị elu (1.6MPa) na oke okpomọkụ (120 ℃).

3. Ụlọ ọrụ mmepụta ihe

Industrylọ ọrụ kemịkalụ: Ibufe mgbasa ozi na-emebi emebi dị ka acid siri ike na alkalis siri ike. Ihe igwe anaghị agba nchara na ụlọ mkpuchi siri ike igwe na-ahụ maka nchekwa (dị ka hydrochloric acid na caustic soda pipeline).

Metallurgy na ike: Ọ nwere ike ngwa ngwa ebipụ gas eruba na mgbawa ọkụ gas pipelines ma ọ bụ mezie eruba ọnụego na jụrụ mmiri pipeline nke thermal ike osisi, adapting na elu okpomọkụ (n'elu 300 ℃) na uzuzu gburugburu.

4. Injinia mmiri na ụgbọ mmiri

A na-eji ya na pipeline mmanụ n'elu ikpo okwu na usoro mmanụ ụgbọ mmiri, na-eguzogide corrosion nke mmiri mmiri ma nwee ike iguzogide mkpọtụ ụgbọ mmiri, ma na-agbaso ụkpụrụ mba ụwa dị ka API 6D.

The n'ụzọ zuru ezu welded bọl valve Pn16, na ya elu ntụkwasị obi, obere mmezi ego na nnukwu mgbanwe na-arụ ọrụ ọnọdụ, aghọwo a isi ihe na-achịkwa ike nnyefe, mmepụta usoro na akụrụngwa ewu, karịsịa irreplaceable na nnukwu pipeline usoro na-achọ ogologo oge kwụsiri ike ọrụ.
