Backlashes between a core of the valve and the plug. It is possible to use two ways of measurement.
– To insert the valve into the plug. To raise the valve on 3 mm from a saddle and to shake here and there, to measure lateral movings of the valve.
– To measure internal diameter of the plug and external diameter of a core of the valve. To take a difference of diameters.
Apertures of directing plugs can be developed on больший the repair size, fig. Expansion of apertures of plugs see. In this case it is necessary to use valves with the increased diameter of a core. |
