All closures nwere a yiri Ọdịdị. Nke a bụ a mechiri emechi akara ụlọ, nke accommodates ọnụ valves. Ọ bụrụ na e na-abụkarị abụọ (na ụfọdụ ogologo) ọgwụgwụ, site na nke ọ na-ike mmasị ka anwụrụ. Ọrụ kpochidoro unit - hermetic nkewa nke pipeline usoro. Na ya Ọdịdị e nwere oche na mechie-apụ ahụ bụ mgbe niile na kọntaktị na oru na-ebupụta.

cranes

Cranes na-eji echichi na paịpụ mmiri, uzuoku na gas na-ebu. Ha na-ji kọmpat size (1.9 n'arọ) na a obere eguzogide. Na dayameta nke tap pụrụ ịbụ 1 3 sentimita asatọ. The kasị ahụkarị ụdị valves dị ka obi ụtọ na plọg. Dị na usoro nke akara, ha na-gland na erughị ala.

A compound nke kreenu na conduit emee site a Flange njikọ ma ọ bụ site na ịgbado ọkụ thereto. Na gas pipelines eji gas njikọ valves. Ihe n'ihi na ha bụ ígwè. Iji hụ na njikọ nke mmetụta dị aṅaa na kreenu, na-achọ na aku. Gas valves na-haziri maka ime ihe nrụgide nke 0,1 MPa na ọnọdụ okpomọkụ 50 Celsius C.

Higher ibu nwere ike idi ihe gland nut taps. Ha ihe ike na mmanụ pipelines na aqueducts, ha isi akụkụ na-mere nke nkedo ígwè. N'ihi ya bụ na ígwè na-juru n'ọnụ gland roba ma ọ bụ hemp. Dị otú ahụ valves nwere ike na-arụ ọrụ na nrụgide ruo 1 MPa na ike idi okpomọkụ ruo 100 Celsius C.

The kasị nta nha bọl valves. Nke a na ngwá bụ ma ama maka elu àgwà nke na-arụ ọrụ, nke na-akọwa na ya iji na nnukwu dayameta pipelines. Ha na-mere nke nkedo ígwè, na akara yiri mgbaaka iso nke PTFE-4. The ọrụ parameters-ederịta akwụkwọ ozi ndị e ji mara na obi ụtọ valves gland nut taps.

Nke a na ngwá na-eji maka pipelines arụ ọrụ na okpomọkụ sitere na site -40 ° C na +70 Celsius C. Ndị a valves na-n'ịnyịnya naanị ekwesị. The ịchịkwa ike ịbụ ma remote na site flywheel.

Mechie-apụ valves

Valves egwu a dị oké egwu ọrụ a ọnụ ọgụgụ buru ibu nke pipeline netwọk nke regulators. Nke a bụ ihe kasị nkịtị stop valves. Gịnị ka ọ bụ, ị pụrụ ịhụ na foto a.

Nke a ihe na-shutter, ọdịdị nke efere ma ọ bụ ewepụghị cone udi, nke na-akpali ihe yiri ka ndị axis nke akara n'elu oche ahụ reciprocates ma ọ bụ aak.

Valvụ - valvụ dịgasị iche iche, na ije nke na-ebu site a threaded kpọchie ụzọ.

The kasị stop valves arụnyere na ọkpọkọ. Ukpụhọde n'akparamagwa ha aka iji a n'aka wheel ma ọ bụ remotely site actuator.

Akara ike dịgidere yiri mgbaaka mere nke akpụkpọ anụ, roba ma ọ bụ PTFE-4. Mechie-apụ valves na-eji piping, nke na-arụ ọrụ na-ajụ bụ ikuku, mmiri ma ọ bụ uzuoku. N'ihi na njikọ na anwụrụ threaded njikọ na-etinyere. N'ihi na ejuputa gland eji Asbestos mbukota AP-31 - Asbestos udo nke braided filaments antifriction impregnation.

The mmiri anwụrụ na mmiri okpomọkụ na-erughị 50 ° C wụnye stop valves njikọ. Nke a na ngwá bụ ike rụọ ọrụ na bụla ọnọdụ. The mmiri aga n'okpuru diski. Nkedo ígwè ụlọ ngwaọrụ, gaskets - paronitovye, akara mgbanaka bụ mere nke akpụkpọ anụ, na mbukota akàrà - Asbestos.

Na pipelines maka iga nke ikuku ma ọ bụ mmiri Wednesday ụtọ na a okpomọkụ nke +45 Celsius C. N'ọnọdụ dị otú engineering netwọk anabata valving eji na akpa actuator. Ọ bụ iji na-arụ ọrụ na okpomọkụ ruo +50 Celsius C. Ọ ga-eduzi elu. Device casing - igba ígwè. N'ihi ya spool na cover na-mere ígwè. Nke a valvụ na-achịkwa ma aka ma ọ bụ remotely.

flaapu

The dampers-e maka ojiji na nnukwu dayameta pipelines. Ha na-arụnyere na ikuku-oyi na ventilashion na ala nrụgide na ala chọrọ maka tightness.

Dabere na ọnụ ọgụgụ nke damper efere ji mee ihe bụ otu na mnogostvorchatymi. N'ihi na mmiri mmiri damper media na-adịghị fọrọ eji n'ihi na ha enweghị ike zuru ezu hụ Itie yitewere akara. N'ihi na gas dampers-eji ezi mgbe. Nke a na-facilitated site mfe na ntụkwasị obi nke imewe. Oge akara aka trotul - ụkpụrụ na-asọpụta anya.

Na mgbakwunye na mfe na ngwaọrụ na-achịkwa, ha nwere a dịtụ ala price na ala arọ. Ikekwe dampers ngwá hydraulically, pneumatically ma ọ bụ electrically.

On ọkpọkọ ụgbọ njem mmiri, na-etinye fere fere flaapu mgbali nke 1.0 MPa. Akara emee site a roba mgbanaka, n'ịnyịnya na uzo nke diski. ngwaahịa ụlọ mejupụtara nkedo ígwè, na a rotary aro ka ígwè.

The shuttering chụpụrụ ihe electric, motorized ugwu elu. Na nke a mbanye aro emi odude ekwesị. The dampers na na-na-achịkwa aka nwere ike arụnyere ọ bụla ọnọdụ.

Onyinye flaps na conduit emee site flanges. Ọzọ usoro nke isonyere bụ ịgbado ọkụ. Operating mgbali valves - 1 MPa. Jikwaa, i nwere ike iji drive.

Na dayameta nke armature eji a mbanye, bụ site 200-1200 mm. Ha ike esịmde 5 kW. The oge nke a na-nọrọ na valvụ oghere ma ọ bụ mmechi, bụ banyere iri na ise nkeji.

shutters

Shutter rotary diski a chọrọ iji kpatụ nsogbu na eruba nke ọkara. Arụ ọrụ na-ajụ maka shutter bụ na mmiri na gas. Ha na-arụ ọrụ a mgbali nke 1.6 MPa na a okpomọkụ nke si -15 ° C 200 Celsius C.

Shutter rotary diski bụ valves. Mgbe ahụ e mechiri emechi ọnọdụ, ọ na-eme ka o kwe omume iji nweta a akara. The uru nke shutter bụ ya ala ewu elu na ogologo. The ngwaahịa na-eji na kpo oku, na mmiri na nri ụlọ ọrụ.

latches

Na engineering netwọk inwe na ndị ọzọ na valves. Gịnị ka ọ bụ "catches" - a ụdị anwụrụ oyiyi akwa?

Lash - nnọchiteanya nke valves enwe a valvụ n'ụdị a nkpirikpi diski ma ọ bụ mpempe akwụkwọ, nke na-akpali tinyere akara mgbanaka ahụ oche. ebe ọkara eruba bụ perpendicular bugharịa shutter. Na dayameta nke akara yiri mgbaaka nwere ike nta karịa ọjà n'obosara, na ike-hà ya. Ke akpa idaha valvụ bụ mmachi, nke abụọ - looping.

Dị na udi nke valvụ shutter ekewa yiri na nkpirikpi.

Ndị a na ngwaahịa na-eji na mmepụta edoghi na ogwe pipelines. The spindle nwere ike ịbụ na valves ma ọ bụ ndị na-abụghị eji bogie. Iji na-emechi ma ọ bụ na-emeghe n'amaokwu Baịbụl ahụ, spindle nwere ime a otutu ọsọ. Ya mere, ndị a valves na-nyere na electric ime akara. Gate valves nwere a na-abụghị ndị na-ebili azuokokoosisi mere nke nkedo ígwè. Ha nrụgide bụ 0,25 MPa. Na dayameta nke valvụ - si 800 na 2000 mm, uka esịmde 14 t.

Uru nke valves:

• -achọrọ iji merie nsogbu nke na-arụ ọrụ ọmụmụ mgbe ndị na-arụ ọrụ ngwa ngagharị;
• kpọmkwem ọmụmụ eruba, nke na-enye ohere na-ebelata na-ala na-eguzogide;
• Symmetrical imewe.

Ụkọ ihe ụfọdụ nke valves:

• ike esemokwu mgbe arụ ọrụ ahụ ngagharị ụzọ ámá;
• nnukwu ewu elu n'ihi na eziokwu na mkpanaka ga-nominated site na ihe abụọ anwụrụ diameters;
• High wear nke shutter na n'etiti ọnọdụ.

Ka mmezi valvụ tube site flanges. Ọtụtụ n'ime ndị akụkụ - igba ígwè. Ihe gaskets - Asbestos, gland mbukota - Asbestos.

Paịpụ erute mmanụ gas na okpomọkụ akara na 100 ° C, na iji abụọ-disk ụzọ ámá valves ígwè. Ha nwere a na-abụghị ndị na-ebili spindle na-arụ ọrụ na nrụgide nke 0,6 MPa. Nye naanị ntuziaka ọrụ.

Yiri abụọ-disk ámá valvụ, ma na-ebili azuokokoosisi enịm na a Coke oven gas e. Ha na-iji na-arụ ọrụ a mgbali nke 1.8 MPa na a okpomọkụ nke 200 ° C.

Na mmanụ edoghi na mmanụ pipelines arụnyere welded ígwè ngọngọ valves. Na ha imewe na-eji a retractable spindle na akpa. The kacha okpomọkụ nke na-ajụ ndị a na valves bụ 250 Celsius C. The ihe onwunwe nke valvụ akụkụ bụ carbon ígwè.

The kpochidoro ngwaọrụ, nke na-arụ ọrụ na a ọjọọ gburugburu ebe obibi, na-ahọrọ na-adabere àgwà nke ọkara. Na ngụkọta oge na oge nke ọrụ, iguzosi ike n'ezi, pụrụ ịdabere, na ndị ọzọ kwa, nke mechie-apụ valvụ. Gịnị bụ na ọ na - kpochidoro ngwá maka corrosive gburugburu?

The valves na-eji corrosive gburugburu mgbe. Otú ahụ na ngwaahịa sadulu na slide na ntukwasi-obi mated, na-ezere esemokwu. Na ebe nke ọnụ akàrà bịara bellows mgbakọ. Na mwepu nke a valvụ bụ ubara haịdrọlik esemokwu.

The mmiri mmiri media-eji ọla njikọ valves mere maka ihe na-arụ ọrụ nrụgide nke 1.6 MPa. Ndị dị otú ahụ a valvụ bụ mmasị na anwụrụ site threaded njikọ.

The uzuoku ọkpọkọ na a mgbali nke 1 MPa na okpomọkụ n'okpuru 50 ° C na valves eji ọla oru mgbanaka. Ndị dị otú ahụ a mgbanaka na spool ka na a roba ma ọ bụ akpụkpọ anụ.

Bellows valves mere ígwè eguzogide corrosion, na-eji na okpomọkụ ruo 350 Celsius C. Flanged valves nwere a poselin ahụ mere nke poselin.

Ndozi

Mmejọ pipeline valves bụ fraught na ọtụtụ ihe ịma aka maka ọrụ ụlọ ọrụ. Ọtụtụ mgbe ha na-adịghị ike na-egbochi ndị na ngalaba nke netwọk, nke agbanweela a okuku. Ọ bụ ihe ọ bụla mberede idozi valves mere na oge, ọ na-enyere ụlọ ọrụ izere elu-akwụ ụgwọ na-eme n'ọdịnihu.
