Abstract
The utility model relates to a decompression protection device, in particular to a decompression protection device for a fast hot faucet which comprises an end cover of one end of a faucet body, a round hole a is arranged on the end cover, and a cylinder block protruding outwards is installed at a place concentric with the round hole a of the end cover. A nut is mounted on the cylinder block, a round hole b is arranged on the nut, a chuck is installed in the cylinder block, a depression film is arranged on a left side of the chuck, a spring is arranged between a right side of the chuck and the nut, and the decompression film abuts against and seals the round hole a under an effect of the spring. According to the decompression protection device for the fast hot faucet, the spring and a flow guide tube are ingeniously arranged outside a shell of a faucet, water vapor is exhausted from the faucet through an opening on a wall of the flow guide tube under water vapor pressure impact in the faucet, so that explosion generated due to too much water vapor accumulated in the faucet is avoided, and self-recovery can be achieved under the effect of the spring.
Description
Technical field
The utility model relates to a kind of decompression protection device, relates in particular to a kind of fast hot water tap's decompression protection device.
Background technique
The Along with people's living standard is become better and better now, and the use of various device is more and more convenient.A dozen are turned on the tap in the winter of cold, just can obtain hot water in a short period of time, and so convenient formerly have only the water heater of use, solar energy just can realize, brought very big inconvenience to aspects such as installation, pipeline connections like this.Newly gone out on the market now can speed heat water tap, the heating pipe heating reaches fast thermal effect to great majority through switching at short notice.The fast hot water tap of existing this respect is because only in set inside single electric leakage or overvoltage overtemperature protection; Water freezing in running into the pipeline in winter; Under the situation such as inner device is damaged, because heat sharply rises in tap, vapor pressure pushes potential safety hazard such as blast.
Summary of the invention
In order to address the above problem, the utility model provides a kind of simple in structure, decompression protection device of forming the fast hot water tap of second protection.
To achieve these goals, the utility model mainly is able to solve through following technological scheme:
A kind of fast hot water tap's decompression protection device comprises the end cap of faucet body one end; Described end cap is provided with circular hole a; The cylindrical piece that be provided with outside protrusion concentric on the said end cap with circular hole a; On the said cylindrical piece nut is housed; Nut is provided with circular hole b; Be provided with dop in the said cylindrical piece; The left side of said dop is provided with the pressure release film, is provided with spring between right side and the nut; Said pressure release film withstands sealing circular hole a under spring action.
As preferably, be provided with honeycomb duct in the said circular hole b.
As preferably, said dop is provided with opening; Said honeycomb duct is connected on the dop and with opening and connects.
The utility model is provided with spring and honeycomb duct cleverly outside the housing of water tap; Vapor pressure impacts down in the tap; Through wall upper shed water vapour is discharged in tap at honeycomb duct; Avoided the too many water vapour of water pipe accumulated and formed blast, and under the effect of spring, can recover automatically.
Description of drawings

The local structural representation that amplifies of Fig. 2 the utility model embodiment's A side.
Embodiment
Below in conjunction with accompanying drawing 1-2, do further bright specifically to the embodiment of the technological scheme of the utility model.
Embodiment: a kind of fast hot water tap's 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 cylindrical piece that be provided with outside protrusion 3 concentric on the said end cap 9 with 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 4, is provided with spring 14 between right side and the nut 5; Said pressure release film 4 withstands sealing circular hole a2 under spring 14 effects, be provided with honeycomb duct 7 in the said circular hole b6, and said dop 8 is provided with opening 11; Said honeycomb duct 7 is connected on the dop 8 and with opening 11 and connects.
In use, at first hydrant is logical powers on the water tap proper functioning; Form protection by the first layer protective gear, after long-term the use, if break down between silver contact a12 and the silver contact b13; After the icing situation of one side perhaps takes place, cause protection to lose efficacy, circuit also is under the normal open state; Heating pipe constantly heats, and temperature raises in the water tap, and vapor pressure increases; This moment, vapor pressure flowed into circular hole a2 extruding pressure release film 4, when pressure acquires a certain degree, because pressure release film 4 closely is connected with bayonet socket 8 tops; Force pressure release film 4 is transmitted on the dop 8, the generation deformation that is stressed of the spring 14 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, and recover the effect of original form under at spring 14 this moment, and dop 8 is got back to pressure release film 4 tops under the state of sealing circular hole a2, so just need not repair and change the pressure release film.
