4.0 INSTALLATION

4.1The SERIES 5000 valve is designed to be mounted between EN, DIN and JIS flanges. When the valve is open, the disc will extend into the pipe on both sides of the valve 一 further on the body side than the seat retainer side of the valve. Piping must be large enough to allow the disc to clear the pipe. Table 1 shows the minimum pipe ID allowable.

CEEB TOOM

Yog tias tus kov lossis tus actuator raug tshem tawm, tsis txhob tig disc dhau qhov qhib lossis kaw tag nrho - qhov no tuaj yeem ua rau muaj kev puas tsuaj rau qhov chaw sealing.

CEEB TOOM:SERIES 5000 li qub yog

equipped with external travel stops to prevent disc over-travel. The valve is opened by turning counter clockwise, closed by turning clockwise. The double "D" flats or keyway at the top of the stem is parallel to the disc edge.

5.0 KEV THOV VAJTSWV

5.1Kev ceev faj tsim nyog yuav tsum tau ua ua ntej pib ua haujlwm ntawm lub valve. Cov khaub ncaws tiv thaiv, raws li qhov xav tau los ntawm cov kua dej tshwj xeeb, yuav tsum hnav.

5.2Tus qauv tsim eccentric ntawm SERIES 5000 tuaj yeem tso cai rau kab siab qhib lub valve yog tias tus kov / actuator tsis nyob rau hauv qhov chaw thaum lub valve nyob rau hauv siab.

CEEB TOOM

Tsis txhob nias cov kab uas tsis muaj tus neeg teb xov tooj mounted ntawm lub valve.

5.3TIPBV SERIES 5000 valve yuav tsum nyob rau hauv qhov chaw kaw kom tshem tawm ntawm kab.

5.4Kev nres tsheb sab nraud tsis yog rau qhov chaw disc. Kev mus ncig nres txwv tsis pub dhau -kev mus ncig ntawm disc hauv qhov qhib thiab kaw. Yog hais tias lub disc txav yog txwv los ntawm kev mus los, lub disc tau overtravelled.

CEEB TOOM

Thaum tuav lub valve, yuav tsum tau saib xyuas kom tsis txhob khawb lub disc ntug lossis lub rooj zaum.

5.5Pib txhua txoj haujlwm ntawm lub valve uas tau raug tshem tawm ntawm txoj kab los ntawm kev ntxuav lub valve, tshem tawm cov grit lossis nplai.

Ua ntej tshem tawm los yog tus actuator los ntawm lub valve, los yog ua ntej tshem lub rooj retainer los ntawm lub valve nyob rau hauv qhov kawg kev pab cuam, kaw lub valve thiab depressuise txoj kab.

Tsis txhob nias cov kab uas tsis muaj tus neeg teb xov tooj mounted ntawm lub valve.

5.6Hloov cov rooj zaum, cov ntsaws ruaj ruaj thiab lwm qhov chaw yog muaj los ntawm cov neeg muag khoom tso cai. Hu rau koj tus neeg muag khoom lossis tus neeg muag khoom kom paub meej txog tus nqi thiab kev xa khoom.

5.7Thaum siv cov yeeb nkab uas nws tus ID yog me dua qhov kev pom zoo tsawg kawg hauv txoj kab uas hla ntawm cov yeeb nkab nrog kev tshem tawm txaus, lub chamfer ntawm 45 degree yuav tsum muab rau ntawm qhov kawg ntawm cov yeeb nkab kom nws tshem tawm cov disc.

6.1 Saib daim duab 1 rau kev txheeb xyuas qhov chaw.

6.2 Nrog rau DISC (2) nyob rau hauv qhov chaw kaw, tshem tawm lub valve ntawm kab.

6.3 Tso lub valve nrog lub DISC (2) nyob rau hauv txoj hauj lwm kaw thiab lub rooj zaum retainer sab pem hauv ntej.

6.4 Tshem cov RETAINER Plate SCREWS (16).

6.5 Carefully clean the seat area in the BODY ⑴ and SEAT RETAINER (15).

Tshem tawm cov khoom txawv teb chaws, av, thiab lwm yam. Tshawb xyuas qhov chaw zaum ntawm lub disc kom pom cov nicks lossis khawb.

6.6 With the DISC ⑵ is in the CLOSED position, place the new SEAT (13) on DISC (2), carefully centering it in the recess in the BODY (1).

6.7 Ua tib zoo tso lub SEAT RETAINER (16) nyob rau hauv txoj hauj lwm saum lub rooj zaum (13).

Maj mam roj cov xov thiab nruab RETAINER Plate SCREWS (16).

7.0 KEV KHO MOB

Stem Seal Leakage 一 Should leakage occur at the stem seals, it may be stopped by retightening the GLAND NUTS (10) to the values.

CEEB TOOM: Yog tias qhov xau tsis tuaj yeem nres los ntawm qhov kev txiav txim no, cov qia foob yuav tsum tau hloov.
