According to the utility model, the water draining connector provided with the atmospheric valve and the temperature controller is mounted at the outlet of the liquid heater, and over-pressure protection and over-temperature protection are realized during the water draining of the liquid heater. The water draining structure for the liquid heater is simple and reasonable in structure, safe and reliable.
Description
Technical field
The utility model relates to the water flowing out structure of a kind of liquid heater, particularly liquid heater.
Background technology
Existing water heater generally is divided into instant electric water heater, storage-type electric water heater, solar water heater and gas heater, wherein, because instant electric water heater's power high (generally more than 3KW) is very big to the load of home circuit, use so fail to popularize; And along with blowing rise the price day of the natural fuels such as coal gas, so gas heater also begins to be eliminated; Remaining solar water heater and storage-type electric water heater all are comparatively energy-conservation products, also therefore be widely used, but since in use hot water can not supply for a long time, cause allowing the more comfortable enjoyment of user be taken a shower.
In use hot water is not enough for solar water heater, storage-type electric water heater, and people develop the liquid heater of main installation and water outlet of water heater mouth, and this heater had not both had overpressure protection, did not have overtemperature prote yet, and the user is not had safety guarantee.
The utility model content
When aiming to provide a kind of simple and reasonable, safe and reliable, water outlet, the purpose of this utility model realizes the liquid heater water flowing out structure of overpressure protection, overtemperature prote, to overcome weak point of the prior art.
A kind of liquid heater water flowing out structure by this purpose design comprises water out adapter, it is characterized in that, described water out adapter is for having at least the pipe fitting of four passages; Wherein, four passages are respectively water inlet, delivery port, pressure relief opening and temperature-measuring port, are respectively arranged with relief valve and temperature controller on pressure relief opening and the temperature-measuring port.
Described relief valve comprises pressure release mouth, silica gel plug and spring; The pressure release mouth is convex shape, and its center is provided with pressure release passage, and the lower end is fixedly connected with pressure relief opening; Be provided with internal projecting ring in the pressure relief opening, be disposed with described silica gel plug and spring between internal projecting ring and the pressure release mouth; The silica gel plug diameter is greater than the internal projecting ring center-hole diameter, and less than the pressure relief opening internal diameter.
Described silica gel plug front end is provided with push rod, and the push rod rear portion is provided with position limiting convex ring.
Described silica gel plug front end is provided with protuberance, and the push rod rear end face is provided with locating slot and the silica gel plug protuberance is connected and fixed.
Be connected with sealing gasket between described pressure release mouth and the pressure relief opening.
Described temperature-measuring port is connected with temperature controller with thermal sensitive piece by sealing ring successively.
The water inlet of described water out adapter is provided with adpting flange.
The utility model is by installing the water out adapter with relief valve and temperature controller in the liquid heater exit, so that realize overpressure protection, overtemperature prote during the liquid heater water outlet.In addition, by combining of relief valve and temperature controller, even a device failure wherein also can be protected liquid heater by another device, avoid causing personal safety.Specifically: when only having relief valve malfunctioning (can not pressure release), if water temperature constantly rises in the liquid heater, then can cause air pressure inside to rise, finally blast, but because the effect of temperature controller, when making water temperature reach the limiting temperature that temperature controller opens circuit, the liquid heater stopped heating, avoid the continuous rising because of internal pressure, and the explosion phenomenon that occurs; When only having temperature controller (can not open circuit) malfunctioning, liquid heater can not stop heating, and relief valve can in time be discharged high-temperature steam, avoids blast, and causes seriousness to burn to the user.

Fig. 2 is structural representation after the utility model assembling.
Fig. 3 is the vertical sectional structure schematic diagram of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 3, this liquid heater water flowing out structure comprises water out adapter 1, and described water out adapter 1 is for having the pipe fitting of four passages; Wherein, four passages are respectively water inlet 1.5, delivery port 1.3, pressure relief opening 1.4 and temperature-measuring port 1.2, are respectively arranged with relief valve and temperature controller 2 on pressure relief opening and the temperature-measuring port.
Relief valve comprises pressure release mouth 9, silica gel plug 5 and spring 7; The pressure release mouth is convex shape, and its center is provided with pressure release passage 9.1, and the lower end is fixedly connected with pressure relief opening 1.4; Be provided with internal projecting ring 1.6 in the pressure relief opening, be disposed with described silica gel plug and spring between internal projecting ring and the pressure release mouth; The silica gel plug diameter is greater than the internal projecting ring center-hole diameter, and less than the pressure relief opening internal diameter.
Temperature-measuring port 1.2 is connected with thermal sensitive piece and is connected with temperature controller 2 by sealing ring 4 successively.
Water inlet 1.5 places of water out adapter 1 are provided with adpting flange 1.1, and water out adapter 1 is connected with the heat-generating pipe outlet of liquid heater by adpting flange 1.1.
Its relief valve operation principle is, when water out adapter 1 internal pressure is excessive, air pressure or water pressure pushing silica gel plug 5 travel forward, internal projecting ring 1.6 centre bores of pressure relief opening 1.4 are no longer by silica gel plug 5 shutoff, water out adapter 1 internal pressure can be discharged outside the water out adapter 1 through pressure release passage 9.1, until water out adapter 1 internal pressure is in the born pressure limit of setting the time, spring resets silica gel plug 5 and seals internal projecting ring 1.6 centre bores.
