Key Points ning Pipeline Valve Installation Specifications

I. Pamagsadya bayu ing pamag-install

1. Lawen me ing valve specification model, pressure level, ampo ing flow direction identification para makasiguradung makatupad ya kareng requirements ning design.

2. Lawen me ing kalinisan ning valve body cavity at ilako la reng packaging protective materials ampo ding aliwang bage.

3. Deng butt welding connection valves kailangan lang prefabricate kareng grooves, ampo deng flange connection valves kailangan lang tsekan ing integridad ning sealing surface.

II. Direksyun ning Pamag-install

1. Ing globe valve ampovertical lift check valvekailangan yang i-install keng direksyun a pepakit ning pana keng katawan ning balbula.

2. keng prinsipyu,alang tatas a stem valve, balbula ning parul a uri ning danum, ampo deng ball valves malyari lang i-install keng adwang direksyun, pero dapat dinan pansin ing ease of operation.

3. Deng electrical / pneumatic valves kailangan lang mag reserve espasyu para keng actuator operation ampo maintenance.

III. Welding Installation Specifications

1. Ing butt welding valve dapat half-open ya kabang mag welding ya para aiwasan ing jamming a sangkan ning thermal deformation.

2. Gamitan me ing argon arc welding para gawan ing base, ampo kontrolan me ing temperatura ning interlayer para e ya lalagpus keng rated a temperatura ning balbula.

3. Kaybat ning welding, kailangan yang subukan ing valve para abalu na normal ya ing pamagbukas ampo pamagsara na.

IV. Key Points ning Flange Connections

1. Ing flange sealing surfaces manatili yang parallel, at ing maximum allowable deviation e ya lalagpus keng 0.15% ning flange outer diameter.

2. Ing gasket dapat ibili ya keng libutad, deng bolts dapat higpitan lang simetriku at pare-pareu, ampo ing rated torque dapat miras ya keng atlung besis.

3. Deng connecting bolts da reng high-temperature valves dapat lang higpitan adwang besis keng mainit a kabilian.

V. Quality Control

1. Ing strength test ampo ing sealing test kailangan la kaybat ning pamag-install.

2. Potang mag-flush ya ing sistema, dapat yang i-bypass ing regulating valve, flow meter ampo reng aliwang kagamitan.

3. Katmuan me ing tala ning pamag-install, kayabe na ing susi a data antimo ing bilang ning posisyun ning balbula, presyur ning pamagsubuk, torque ning pamagobra, atbp.

Tandanan: Ing balbula e ya dapat gamitan bilang suporta para keng pipeline. Deng mangaragul a balbula mangailangan lang miyayaliwang support frame. Kaybat ning pamag-install, ing balbula dapat makasara ya at protektadu para aiwasan ing pangasira ning cross-operation.
