Embodiment
The present invention provides a kind of anti-scald water tap, to make the purpose of the present invention, technical scheme and effect clearer, bright
Really, developing simultaneously referring to the drawings, the present invention is described in more detail for embodiment.It should be appreciated that specific implementation described herein
Example is not intended to limit the present invention only to explain the present invention.
Herein, the preceding direction referred to away from wall, after refer to close to the direction of wall.
Fig. 1-4, a kind of anti-scald water tap, including housing 1 are referred to, and the core pipe 2 being plugged in housing；The core pipe
Both ends offer cold water inlet 21 and water inlet of hot water respectively（Do not have picture in figure, herein, cold water inlet and water inlet of hot water pair
Claim to set）, the middle part of core pipe 2 offers upper water-out mouth 22 for being supplied water to showerhead and for being supplied water to Tap for bathtub
Lower outlet（Do not have picture in figure, herein, upper water-out mouth and lower outlet are on same vertical curve）, accordingly, housing both ends are opened
Provided with cold water connector 11 and hot water connector 12, housing central section offers connector 13 and lower connector 14；Core pipe 2 is close
One end of cold water inlet 21 is provided with flow valve element 3, and the flow valve element is connected with flow handwheel 31, and the other end of core pipe is set
There is gear valve element 4, the gear valve element is connected with gear handwheel 41；Core pipe is respectively communicated with outer cold water pipe by two connecting tubes 5
Road and hot water pipeline；There is gap between the inner surface of housing 1 and the outer surface of core pipe 2.
Due to having gap between housing 1 and core pipe 2, when hot water flows through from core pipe 2, heat is difficult to be delivered to housing
On, therefore housing can be prevented by hot water heating, so as to avoid user from being scalded by housing.
Specifically, see Fig. 1,2, the external diameter of the core pipe 2 is less than the internal diameter of housing 1, on the outer wall of core pipe along its length
Multiple annular projections 23 are provided with, the external diameter of annular projection and the internal diameter of housing are adapted.Core pipe is supported on by annular projection
In housing, heat-insulated gap is formed.
Further, the pipe of one section of body 24 in core pipe between water inlet of hot water and upper water-out mouth/lower outlet
Footpath is less than the caliber of other parts.Because hot water mainly flows through from this section of body 24, it can be increased by reducing the caliber of this section
Gap between housing, improve effect of heat insulation.
In order to realize the quick and precisely alignment for corresponding to connector in core pipe on entery and delivery port and housing, set on the inwall of housing 1
It is equipped with the positioning convex extended along its length（Do not have picture in figure）, corresponding locator card is offered on the annular projection 23 of core pipe 2
Groove 231.After locating groove is directed at positioning convex during assembling, core pipe is inserted in housing, core pipe can not in housing internal rotation, from
And realize and be quick and precisely aligned.
In the present embodiment, core pipe 2 is by high temperature resistant nylon（The PPA plastics being commonly called as）It is made；The housing 1 is by copper alloy system
Into.There is high temperature resistant nylon resistance to elevated temperatures will not be deformed easily due to the high temperature of hot water, and its low thermal conductivity can reduce
The heat passed out, and copper alloy has larger density and specific heat capacity, the required heat that heats up is larger, therefore is not easy to rise
Temperature, the pairing use of two kinds of materials substantially increase anti-scald effect.
Specifically, seeing Fig. 1,3, the connecting tube 5 is bent pin, when the pitch-row for the water exit position reserved on wall has deviation shadow
When ringing installation, this influence can be offset by the angle for adjusting bent pin.
Further, screen pack 51 is provided between the connecting tube 5 and core pipe 2, to avoid the impurity in water from flowing into water
In tap.
Further, check-valves 52 is provided between the screen pack 51 and core pipe 2, to prevent the water in water tap from returning
Stream.
In the present embodiment, Fig. 3 is seen, feedthrough 53 is plugged with the cold water inlet and water inlet of hot water of core pipe 2, connect
First 53 rear end（Refer to the direction away from core pipe afterwards）Passed from cold water connector 11 or hot water connector 12 and be connected with connection spiral shell
Mother 54, the connection rear end of nut 54 are connected with connecting tube 5；Jump ring 55, check-valves 52 are disposed with feedthrough 53 from front to back
With screen pack 51, the junction of feedthrough 53 and core pipe 2, feedthrough 53 with connect the junction of nut 54 be provided with it is O-shaped close
Seal 56；Sealing gasket 57 and Decoration cup 58 are provided between connection nut 54 and connecting tube 5, Decoration cup 58 is solid by abnormity circle 59
It is scheduled in connecting tube 5.
Specifically, seeing Fig. 1,4, connector 6 has been connected through a screw thread respectively on the upper connector 13 and lower connector 14；
Each connector 6 includes putting in the plug division 61 of upper water-out mouth 22 or lower outlet, connects with upper connector 13 or lower connector 14
The first threaded portion 62 connect, and the second threaded portion 63 for being connected with showerhead or Tap for bathtub；The diameter of plug division 61
Less than the diameter of the first threaded portion 62, the diameter of the first threaded portion 62 is less than the diameter of the second threaded portion 63, and is arranged with plug division 61
One sealing ring 90, the second sealing ring 91 is arranged with the first threaded portion 62.After housing 1 being inserted by core pipe 2, then connector 6
It is screwed into, position-limiting action is risen to the axial location of core pipe, assembles simple and fast.
Preferably, Fig. 1 is seen, between flow valve element 3 and flow handwheel 31 and between gear valve element 4 and gear handwheel 41
Wear-resisting ring 7 is provided with, to increase service life.
It is understood that for those of ordinary skills, can be with technique according to the invention scheme and its hair
Bright design is subject to equivalent substitution or change, and all these changes or replacement should all belong to the guarantor of appended claims of the invention
Protect scope.
