GENERAL REMARK

Regulators type: 143 and type 143-BV are devices whose function is to maintain the value of the

controlled pressure within its tolerance field irrespective of inlet pressure disturbance.

Regulators type: 143 and type 143-BV are pilot controlled regulators in which the net force required to

move the control member is supplied by pilot regulator.

Regulators type: 143 and type: 143-BV are designed and manufactured according to EN 334 and 14382.

Conformity to Directive 2014/68/EC and CE marking of pressure regulator and relevant accessory

requires installation on system with minimum requirements according to: EN 12186 and EN 12279.

Only accessories produced and labeled by GasTeh can be incorporated to regulators type: 143 and type:

143- BV as additional pressure accessories (e.g. filters, silencers, etc.).

For problems with regulators type: 143 and type 143-BV with incorporated pressure accessories produced

by other manufacturers, GasTeh will not be responsible.

OPŠTE PRIMEDBE

Regulatori pritiska tip:143 i tip:143- BV su uređaji čija je funkcija obezbeđivanje konstantne vrednosti

izlaznog pritiska u okviru regulacione grupe, nezavisno od promene ulaznog pritiska.

Regulatori pritiska tip:143 i tip:143- BV su pilotski regulatori kod kojih se sila potrebna za održavanje

konstantnog pritiska dobija iz pilota.

Regulatori pritiska tip:143 i tip:143- BV su konstruisani i proizvedeni u skladu sa EN 334 i EN 13482.

Usklađenost sa direktivom PED 2014/68/EC i CE označavanje regulatora pritiska i odgovarajućih

uređaja zahteva instalaciju na sisteme u skladu sa odredbama EN 12186 i EN 12279.

Kao dodatni uređaji pod pritiskom dodati regulatorima pritiska tip:143 i tip:143-BV, moraju se koristiti

isključivo oni proizvedeni od strane GasTeh-a (npr: filteri, prigušivači, itd.).

Za probleme nastale korišćenjem dodatnih uređaja drugih proizvođača na regulatorima pritiska tip:143

i tip:143- BV, GasTeh neće biti odgovoran.

MONTAŽA

Montažu mogu da vrše samo stručna i osposobljena lica. Pogledati sliku 1.

! UPOZORENJE !

Ventilacioni vodovi moraju biti obezbeđeni u sistemima gde se instalira gasna oprema (EN 12186 i

EN 12279)

Vodovi za odmuljenje moraju biti obezbeđeni na opremi pre regulatora i blokadnog

mehanizma ( EN 12186 i EN 12279).

Pre početka izvođenja montaže, pregleda ili održavanja, lice mora da:

- proveri sigurnosne uslove koji se odnose na instalaciju u kojoj treba da radi

- ukoliko je potrebno, pribavi sve dozvole za rad

- koristi neophodnu zaštitnu opremu

- obezbedi da prostor u kome se radi ima uređaje za opštu bezbednost i uređaje za sigurnosnu indikaciju

Pre montaže regulatora potrebno je obezbediti:

- očistiti cevovode, proveriti da li je regulator čist i da nije oštećen prilikom transporta

- da se regulator može postaviti na predviđeno mesto

- da su ulazni i izlazni cevovodi saosni

- da su ulazna i izlazna prirubnica paralelne i čiste

- proveriti podatke na tablici regulatora, da li se slažu sa zahtevanim radnim parametrima

- proveriti da li je smer proticanja gasa istog smera kao i strelica na telu regulatora

Oprema pod pritiskom mora biti instalirana na mestima neugroženim seizmičkom aktivnošću, ne sme biti

izložena požaru i mora biti obezbeđena električna izolovanost i katodna zaštita.

Regulator može biti montiran i u drugim položajima (konsultovati tehnička lica GasTeh-a).

Pre puštanja u rad regulatora i blokadnog mehanizma, impulsni vodovi moraju biti povezani sa

impulsnim priključcima na cevovodu. Impulsni vodovi treba da se izvedu cevima od nerđajućeg čelika ili

bakarnim cevima prema veličini regulatora..

GT-143-02 12

COMMISSIONING

After installation check that the inlet/outlet on/off valves , by-pass and other lines are closed.

The regulator and safety shut-off device is factory set at approximately the midpoint of the pressure

requested, so an initial adjustment may be required to give the desired results.

With proper installation completed, slowly open the inlet valve.

PUŠTANJE U RAD

Nakon instalacije, proveriti da li su ulazna/izlazna slavina, by-pass linije i ostale linije zatvoreni.

Regulator i blokadni mehanizam su fabrički podešeni na sredinu zahtevanog opsega pritisaka, tako da je

možda potrebno eventualno malo podešavanje da bi se ostvario zahtevani pritisak. Nakon uspešno

izvedene instalacije, polako otvoriti ulaznu slavinu.

ADJUSTMENT (See pilot drawing, Picture 3.)

Outlet pressure of regulator is setted on the pilot. To change the outlet pressure, remove the cover (08)

from regulating screw carier (05), unscrew the nut (13) and turn the regulating screw (06) clockwise to

increase outlet pressure or counter clockwise to decrease outlet pressure. Setting pressure monitor with a

test gauge downstream the regulator.

PODEŠAVANJE (Pogledati sliku pilota, Slika 3.)

Izlazni pritisak regulatora se podešava na pilotu. Za podešavanje izlaznog pritiska potrebno je prvo

skiniti poklopac (08) sa nosača regulacionog zavrtnja (05), odviti navrtku (13) i odviti ili zaviti

regulacioni zavrtanj (06). Okretanjem regulacionog zavrtnja u smeru kazaljke na satu dolazi do

povećanja izlaznog pritiska, dok okretanjem u suprotnom smeru, izlazni pritisak opada. Podešavanje

pritiska se prati na manometru iza regulatora.

DECOMMISSIONING

WARNING! To avoid personal injury resulting from sudden release of pressure, isolate the regulator

from all pressure before attempting disassembly and release trapped pressure from the regulator and

pressure line.

In case of disassembly of main pressure retaining parts for checks and maintance procedures, exernal and

internal tightnes tests have to be done according applicable codes.

ISKLJUČIVANJE

UPOZORENJE! Da bi se izbegle povrede radnika nastale neočekivanim povećanjem pritiska, potrebno

je regulator izolovati od svih mogućih pritisaka, i nakon toga ispustiti pritisak iz regulatora i linije.

Nakon demontaže glavnih delova regulatora koji su izloženi pritisku, potrebno je uraditi ispitivanje

nepropusnosti u skladu sa primenjenim standardima.

GT-143-02 13

CHECKS AND MAINTENANCE

WARNING! Maintenance should be carried out only by qualified, skilled personnel.

It is recommended that the regulator be periodicly checked in order to ensure its proper functioning. The

frequency of inspection/checks and replacement depends upon severity of service conditions and upon

applicable standards and regulations. Regulator and its pressure accessories are subjected to wear and

must be inspected periodicly and replaced as necessary. Before carrying out maintenance, be sure that no

gas under pressure is trapped in the regulator. First close inlet and outlet valve and then release gas from

the line by opening the vent line.

Maintenance operations do not require removal the body from the line.

When carrying out maintenance procedures, replace all rubber parts.

Regulator drawing and specifications are required to start with maintenance.

Checking regulator

Slowly close the outlet valve and check pressure with a test gauge downstream the regulator. If the

system is functioning properly, an increase in outlet pressure will be noticed due to lock-up pressure, after

which pressure will stabilize. If pressure value is constant, in range of lock-up pressure class (SG),

regulator is functioning properly. If outlet pressure increase, more than defined in lock-up pressure class

(AG), slowly close inlet valve and call service personel from GasTeh to carry out general maintenance of

regulator. For checking function of regulator, slowly close outlet valve, and open relief valve downstream

the regulator, and check pressure oscilating. If presure is constant, regulator is functioning properly. If

pressure value oscillates, slowly close inlet valve and call service personel from GasTeh to carry out

general maintenance of regulator.

General maintenance of regulator

PREGLEDI I ODRŽAVENJE

UPOZORENJE! Održavanje mogu da izvode samo stručna i osposobljena lica.

Preporučuje se povremena provera rada regulatora kako bi se obezbedilo njegovo ispravno

funkcionisanje.

Učestanost pregleda i zamena delova zavisi od više uslova i primenjenih regulativa i standarda. Delovi

regulatora izloženi su habanju i moraju periodično biti kontrolisani i zamenjeni ukoliko je potrebno. Pre

početka kontrolisanja proveriti da regulator nije pod pritiskom. Zatvoriti ulaznu i izlaznu slavinu i preko

ispusnog voda isprazniti liniju.

Za operacije održavanja regulatora na terenu, regulator nije neophodno skidati sa linije.

Prilikom izvođenja održavanja potrebno je sve delove od gume zameniti novim.

Prilikom izvođenja održavanja potrebno je imati uputsvo za rukovanje sa crtežom regulatora i spiskom

sastavnih delova.

Pregled regulatora

Prilikom pregleda regulatora, polako zatvoriti izlaznu slavinu iza regulatora i kontrolisati vrednost

pritiska pomoću manometra iza regulatora. Ako je vrednost pritiska konstantna, i u okviru zatvorne grupe

(ZG), rad regulatora je ispravan. Ukoliko vrednost izlaznog pritiska raste izvan granice zatvorne grupe

(ZG), rad regulatora nije ispravan i potrebno je zatvoriti ulaznu slavinu pre regulatora. Regulator je

potrebno servisirati i u tom slučaju pozovite stručno osoblje iz GasTeh-a. Za proveru rada regulatora,

zatvorite izlaznu slavinu iza regulatora i pomoću odušne slavine posle regulatora, otvaranjem iste,

proveriti rad regulatora. Ukoliko je rad regulatora bez oscilacija, rad je ispravan. Ukoliko rad

regulatora ima oscilacije, regulator je potrebno servisirati i u tom slučaju pozovite stručno osoblje iz

GasTeh-a.
