Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
First embodiment
See Fig. 1-Fig. 4, this electric water heater safety valve, comprise valve body 5, interior pressure relief device A and outer pressure relief device B, valve body 5 inside is formed with T-shaped passage by longitudinal and transverse two passages merge, and interior pressure relief device A and outer pressure relief device B is assemblied in longitudinal and transverse passage respectively.
Interior pressure relief device A comprise successively through spool 15, valve pocket 13 and position shelf 10 valve rod 12 and be bolted in the valve seat 17 of valve body 5 inner end.Valve rod 12 one end is movable to be placed in valve seat 17, and the other end is movable runs through position shelf 10; Valve seat 17 1 end is raised with tip or curved portions against the gasket seal 16 be assemblied on spool 15, valve pocket 13 is bolted on valve rod 12, all sides are propped up toward extension and hold the end in spool 15, locate valve rod 12 up and down, be provided with the Returnning spring 14 of ring set valve rod 12 between spool 15 and valve pocket 13, give valve rod 12 elastic force; Position shelf 10 is fixed in valve body 5, is provided with the interior pressure release stage clip 11 of taper between itself and spool 15.
Outer pressure relief device B comprises successively through the pull bar 2 that silica gel sheath 7, look nut 1 and water seal cover 4 end are exposed, the other end of pull bar 2 connects silica gel sheath 7, silica gel sheath 7 is provided with silicagel pad 8, as its name suggests, silicagel pad 8 is silica gel material, in valve body 5, the split type Boss features 9 of being inlaid with seals with silicagel pad 8 and fits, and the leakage of effective anti-sealing causes product seal failure.Boss features 9 is embedded in the intersection of longitudinal and transverse passage in the mode of closely firmly pressing, and its two ends are communicated with longitudinal and transverse passage respectively, fit tightly, reach sealing purpose under normal pressure with silicagel pad 8.The structure of setting is integrated compared to traditional boss and valve body, this vibrational power flow Boss features 9 and valve body 5 are split, the material of such Boss features 9 is just no longer restricted, different corrosion resistant metallic material can be adopted, the Boss features 9 of this structure adopts corrosion resistant 317L stainless steel material, guarantees the sealing that product uses for a long time.
Specifically, join Fig. 4, Boss features 9 is in sleeve, and the end week side of its pressure relief device B toward the outside extends into alar part 9.3 outward, and alar part 9.3 has positioning action; Axial direction is prolonged in this end, and to be raised with cross section be pointed or the sealed department of arc 9.4, and pointed or arc effectively can improve the sealing between itself and silicagel pad 8, fits tightly under normal pressure under the elastic force of stage clip 6 with silicagel pad 8; Boss features 9 surface is with tapering, and maximum diameter is slightly larger than pilot hole internal diameter, to realize interference fit, makes firmly overall; Boss features 9 surface is provided with the O type groove 9.2 for fitting tight part 9.1, Sealing 9.1 reality is for being located on the seal ring on Boss features 9 surface, its cooperation is assemblied in tool withdrawal groove 9.2, because valve body 5 is generally different materials from Boss features 9, therefore chemical potential is each other different, can corrode mutually during both contacts, therefore, the setting of Sealing 9.1 can effectively guarantee its sealing.
In addition, be provided with the stage clip 6 of ring set pull bar 2 between silica gel sheath 7 and look nut 1, under normal pressure, active silicon rubber cushion 8 fits tightly Boss features 9, realizes sealing.Pull bar 2 Moveable plug is located at look nut 1 and water seal cover 4, and look nut 1 and water seal cover 4 are assemblied in valve body 5 in the mode be spirally connected respectively, and water seal cover 4 one end face exposes, and the mating face of itself and pull bar 2 and valve body 5 is respectively arranged with seal ring, Leakage prevention; There is the gap of 0.5mm between look nut 1 and water seal cover 4, even if look nut 1 is slided tooth or got loose, it is very small for changing the elastic force of stage clip 6, and silicagel pad 8 still can seal up Boss features 9, and current can not leak, and plays the effect preventing seal failure.Valve body 5 between silica gel sheath 7 and look nut 1 is provided with pressure relief opening 18, and the water that pressure release produces is discharged from pressure relief opening 18.Pull bar 2 exposed junction is flexibly connected manual components 3, and manual components 3 one end is fixed on valve body 5 by screw, and the other end is resisted against on the exposed face of water seal cover 4.
Second embodiment
There is the gap of 0mm between the look nut 1 of the present embodiment and water seal cover 4, namely contact with each other, this structure is effectively avoided the sliding tooth of look nut 1 or is got loose on the impact of stage clip 6 elastic force.
Above-mentioned is preferred version of the present utility model, and those of ordinary skill in the art, to its simple modification or transformation, all drop within protection domain of the present utility model.
