Open the pressure relief valve core hole with what
Eccentric semi ball valve you say is a kind of ball valve, ball valve is a relatively new category, it has some advantages of own unique structure is divided into a type eccentric semi ball valve and side mounted eccentric semi ball valve in the maintenance of several, mainly according to the structure to pack type eccentric semi ball valve the structure is with a cover, can be in the pipeline maintenance, convenient and labor-saving, eccentric semi ball valve in the appearance structure for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and the cost, and side mounted valve has the advantages of compact structure, light weight, suitable for valve installation space requirements.
Attention to maintenance methods of eccentric hemisphere valve:1, eccentric hemisphere valve in the closed state, there is still pressure fluid inside the valve body.2 、 before repair, release the line pressure and make the valve in the open position.3. New parts should be cleaned before assembly.4. Remove the actuating mechanism from the support before servicing.5, non-metallic parts cleaning should be immediately removed from the cleaning agent, not long immersion.6, need to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution.
