Embodiment
Below in conjunction with accompanying drawing 1-4, do further bright specifically to the embodiment of the technological scheme of the utility model.
Embodiment 1: a kind of fast hot water tap's dual decompression protection device comprises the end cap 9 of faucet body 1 one ends; Described end cap 9 is provided with circular hole a2; The arranged outside of said circular hole a2 has pressure release film 12, and the inboard is set with the pressure release piece 4 of hollow box structure; Said pressure release piece 4 is provided with the hole 10 that is communicated with circular hole a2 with the wall that contacts of end cap 9, and other walls are provided with hole b11; In the said hole b11 thimble 14 is housed; Said thimble 14 through spring a15 from interior to the external sealed hole b11; Said circular hole a2 outwards protrudes and forms boss 13; Said pressure release film 12 is buckled on the boss 13 through the convex fixture block (18) at its edge.
In use, at first hydrant is logical powers on, and the water tap proper functioning forms protection by the first layer protective gear; After long-term the use,, perhaps, cause overvoltage protective device to lose efficacy owing to after the situations such as the weather reason takes place to freeze in the tap if break down between silver contact a19 and the silver contact b20; This moment, circuit also was under the normal open state, and water circulates from water pipe, and heating pipe constantly heats; Temperature raises in the water tap, and vapor pressure increases, and the air pressure in the water tap begins to push the taper thimble 14 on the pressure release piece 4; When pressure acquired a certain degree, taper thimble 14 promoted spring a15 and deforms, and breaks away between taper thimble 14 and the hole b11 and comes; Water vapour flows in the pressure release piece 4 from the slit between taper thimble 14 and the hole b11, and flow out in the hole 10 from the pressure release piece 4 again, impacts pressure release film 12 through circular hole a2; Be under pressure in the middle of the pressure release film 12 and broken through, water vapour flows out from the flow-guiding mouth of honeycomb duct 7 again, and can not expand because of water vapour in the water tap like this sets off an explosion.For the water vapour security consideration of flowing out, install the cooperation of adopting nut 5 and dop 8 at honeycomb duct 7, pressure disappears after closing heating pipe; Recover the effect of original form under at spring a15 this moment; Force taper thimble 14 again near airtight, so just need not be repaired replacing and can use repeatedly between taper thimble 14 and the hole b11; When repairing water tap, also can change, to arrive the effect of dual structure pressure release pressure release film 12.
Embodiment 2: a kind of fast hot water tap's dual decompression protection device comprises the end cap 9 of faucet body 1 one ends; Described end cap 9 is provided with circular hole a2; The arranged outside of said circular hole a2 has pressure release film 12, and the inboard is set with the pressure release piece 4 of hollow box structure; Said pressure release piece 4 is provided with the hole 10 that is communicated with circular hole a2 with the wall that contacts of end cap 9, and other walls are provided with hole b11; In the said hole b11 thimble 14 is housed; Said thimble 14 through spring a15 from interior to the external sealed hole b11.The cylindrical piece that be provided with outside protrusion 3 concentric on the said end cap 9 with said circular hole a2; On the said cylindrical piece 3 nut 5 is housed; Nut 5 is provided with circular hole b6; Be provided with dop 8 in the said cylindrical piece 3; The left side of said dop 8 is provided with pressure release film 12, is provided with spring b16 between right side and the nut 5; Said pressure release film 12 withstands sealing circular hole a2 under spring 16 effects, be provided with honeycomb duct 7 in the said circular hole b6, and said dop 8 is provided with opening 17; Said honeycomb duct 7 is connected on the dop 8 and with opening 17 and connects.
In use, at first hydrant is logical powers on, and the water tap proper functioning forms protection by the first layer protective gear; After long-term the use, if break down between silver contact a19 and the silver contact b20, perhaps owing to after the situations such as the weather reason takes place to freeze in the tap; Cause overvoltage protective device to lose efficacy, this moment, circuit also was under the normal open state, and water circulates from water pipe; Heating pipe constantly heats, and temperature raises in the water tap, and vapor pressure increases; Air pressure in the water tap begins to push the taper thimble 14 on the pressure release piece 4, and when pressure acquired a certain degree, taper thimble 14 promoted spring a15 and deforms; Break away between taper thimble 14 and the hole b11 and come, water vapour flows in the pressure release piece 4 from the slit between taper thimble 14 and the hole b11, and flow out in the hole 10 from the pressure release piece 4 again; Water vapour is 10 inflow circular hole a2 extruding pressure release films 12 from the hole, when pressure acquires a certain degree, because pressure release film 12 closely is connected with bayonet socket 8 tops; Force pressure release film 12 is transmitted on the dop 8, the generation deformation that is stressed of the spring b16 between dop 8 and the nut 5, and this moment, water vapour was through formation space inflow between pressure release film 4 and the circular hole a2; Water vapour upwards flows and flows in the honeycomb duct 7 from the opening 11 of dop 8 sidewalls, and water vapour flows out from the flow-guiding mouth of honeycomb duct 7, and can not expand because of water vapour in the water tap like this sets off an explosion.Pressure disappears after closing heating pipe; Recover the effect of original form under at spring a15 this moment; Force taper thimble 14, again near airtight, spring b16 also recovers original form when pressure disappears between taper thimble 14 and the hole b11; Get back to pressure release film 12 tops under the state of sealing circular hole a2 at dop 8 under the effect of spring b16, so just need not repair and change pressure release film 12.
