Fig. 1. interior row's electric water heater one-way relief valves assembly schematic representation
Now in conjunction with the accompanying drawings the structure of arranging the one-way relief valves assembly in adjustable is described in detail:
By Fig. 1, the top inner chamber (20) of valve body (6) left part has female thread (21), spring cup (12) is housed in the inner chamber (20), less and suit one spring (9) of spring cup (12) lower diameter, spring (9) bottom is sleeved on above the step (22) of plum blossom spool (8); Spring cup (12) is passed in the upper end of plum blossom spool (8), suit rubber gasket (7) on plum blossom spool (8) bottom stage, rubber gasket (7) bottom surface just in time contacts with nose (23) in valve body (6) the left part inner chamber, and a look nut (11) is housed in the inner chamber of plum blossom spool (8); Pocketed springs (10) on the step of this nut (11) bottom, spring (10) lower end contacts with step (24) in plum blossom spool (8) inner chamber, pressure regulating screw (13) lower end suit one conical gasket (5), sealing pad (5) cooperates with the taper hole of plum blossom spool (8) bottom; The helical thread portion of pressure regulating screw (13) upper end matches with look nut (11).Conical gasket (5), rubber gasket (7), spring (9) and (10), look nut (11), pressure regulating screw (13), plum blossom spool (8) are formed one-way valve valve body (a 6) lower left quarter outer end jointly external screw thread (25), and the inner chamber of lower left quarter (26) is littler than inner chamber (20) diameter of upper left quarter.This inner chamber (26) is used for pressure release.
The inner chamber (27) of valve body (6) right part becomes vertical position with the inner chamber (20) of left part, is interpenetrated by cross-drilled hole (28).Pull bar (16) is horizontally placed in the inner chamber (27), and left end suit one top board (4), right part suit one look nut (17), spring (15) are contained between top board (4) and the look nut (17); In top board (4) the left end step sealing gasket (14) is housed, sealing gasket (14) left side contacts with the nose (29) of inner chamber (27) bottom, inner chamber (27) right part has female thread, inner chamber (27) right-hand member setting-in one back-up ring (18), pull bar (16) right-hand member stretches out outside the back-up ring (18) and fixes a hook-type handle (1) with rivet (19), and hook end aperture and nut (3) that screw (2) passes handle (1) are fixed in the screw hole (30) of valve body (6) lower right part.Valve body (6) lower right part also extends perpendicular step (31) and porose (32).
