Description
Technical field
The utility model relates to a kind of water heater, relates in particular to a kind of overflow-preventing device of water heater intake-outlet.
Background technology
At present, raising along with people's living standard, water heater has been come into huge numbers of families, water heater can be divided into electric heater according to the principle difference, gas heater, solar water heater, four kinds of water heaters of air-source water heater, most of water heater is provided with water tank and the water inlet pipe and water outlet pipe of water storage, if water inlet pipe and water outlet pipe directly inserts in the intake-outlet of water tank, because thereby there is certain gap in the human factor such as unbalance stress deformed damaged during rough untidy and artificial installation of hole wall, cause foamed material to exosmose, in order to prevent flash, usually at intake-outlet overflow-preventing device is installed, as shown in Figure 1, overflow-preventing device integral body in the market is circular configuration, when behind the shell reel with shell on hose nozzle be oval, and its flange 12 is planar structure, and just so that overflow-preventing device can not cooperate closely with the shell hose nozzle, there is certain gap in this; Secondly, existing overflow-preventing device and shell do not have location structure in center of circle direction, overflow-preventing device also and then rotates and causes overflow-preventing device to screw out when the rotation water pipe, in addition, existing overflow-preventing device just is stuck in shell in the groove by the very little sealing indent 11 of a circle back-off amount, when fastening water inlet pipe and water outlet pipe or when being subject to foamed material and outwards pushing, easily overflow-preventing device is taken out of, do not have corresponding anti-flash effect thereby causing comes off, so that water pipe position flash phenomenon is serious.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of overflow-preventing device of water heater intake-outlet is provided, with solve traditional overflow-preventing device cooperate with shell not tight, easily with water inlet pipe and water outlet pipe rotation, and because of the outside caducous problem of extruding of foamed material.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of overflow-preventing device of water heater intake-outlet, overflow-preventing device is opened type in two ends up and down, and an end is provided with flange, and described flange is stuck on the shell and with it and closely cooperates, and be provided with one on the overflow-preventing device and enclose the sealing indent of fixation, and be evenly equipped with a plurality of catchings.
Preferably, described overflow-preventing device integral body is ellipsoidal structure, and it can closely cooperate with the oval hose nozzle of reel rear casing.
Preferably, described overflow-preventing device is symmetrically arranged with 2 locating dowels that match with breach on the shell in center of circle direction, guarantees that overflow-preventing device can not rotate with water inlet pipe and water outlet pipe.
Preferably, described catching is 6, has increased the back-off amount, has further fixed overflow-preventing device, prevents that it from coming off.
Preferably, described flange is provided with radian, closely cooperates with the cambered surface of bucket in the shell, so that anti-flash dress and shell applying gapless.
Preferably, the semicircle that corresponding locating dowel position has for the prompting installation direction on the described flange indicates mouth, has substituted and has adopted the arrow of projection to represent, the convenient operation workman installs.
The beneficial effects of the utility model are, the overflow-preventing device of described water heater intake-outlet is by keeping original sealing indent, and set up catching, increased the back-off amount, fixed, efficiently solve the problem that causes overflow-preventing device to come off because of the outside extruding of foamed material, and overflow-preventing device integral body is ellipsoidal structure, cooperate tightr with the oval hose nozzle of reel rear casing, its flange is provided with certain radian, cooperate tightr with the cambered surface of bucket in the shell, the applying gapless plays better anti-flash effect, in addition, the semicircle of offering on the flange indicates a mouthful handled easily workman and installs, and the locating dowel that matches with breach on the shell that center of circle direction is set up on the overflow-preventing device has effectively prevented the overflow-preventing device transfer.

Among the figure:
11, sealing indent; 12, flange; 21, indicate mouth; 22, flange; 23, locating dowel; 24, catching; 25, sealing indent; 31 shells.
The specific embodiment
Please refer to shown in Fig. 2 to 3, in the present embodiment, a kind of overflow-preventing device of water heater intake-outlet, overflow-preventing device integral body is ellipsoidal structure, two ends are opened type up and down, the lower end is provided with flange 22, flange 22 is provided with certain radian, its be stuck on the shell 31 and with shell in the cambered surface of bucket closely cooperate, the semicircle that corresponding locating dowel 23 positions also have for the prompting installation direction on the flange 22 indicates mouth 21, be provided with one on the overflow-preventing device and enclose the sealing indent 25 of fixation, and be evenly equipped with 6 catchings 24, and overflow-preventing device is symmetrically arranged with 2 locating dowels 23 that match with breach on the shell 31 in center of circle direction.
During installation, according to indicating mouthful 21 positions, breach on the corresponding shell 31, overflow-preventing device is packed into, so that its flange 22 is stuck on the shell 31, and the locating dowel on the overflow-preventing device 23 is stuck in the breach on the shell 31, simultaneously, shell 31 is stuck in the sealing indent 25, and is further fixed chucking by catching, like this, overflow-preventing device just tightly is fixed in the shell on the bucket, after injecting foamed material between outer cover of water heater and the inner bag, and can be because outwards extruding and not coming off of foamed material, and because the design of the whole ellipsoidal structure of overflow-preventing device, cooperate closelyr with the oval hose nozzle of reel rear casing, and flange 22 is provided with certain radian, cooperates tightr with the cambered surface of bucket in the shell, the applying gapless can play enough anti-flash effects like this.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
