Abstract
The utility model discloses an inflatable emptying device whose structure comprises a one-way valve and a hose. One end of the one-way valve is connected with an aerating device, and the other end of the one-way valve is communicated with supply and drainage water pipes which are communicated with the hose arranged in a water tank; the other end of the hose is provided with a weight loading block. The utility model is the device matched with the solar energy water heater and solves the problem that the outdoor supply and drainage water pipes which are used to supply and drainage water for the water tank of the solar energy water heater can not be frozen in any weather situation. The utility model having the features of simple structure, low cost, convenient use, easy installation, convenient maintenance, etc. enlarges the use range of the solar energy water heater, extends the service life of the solar energy water heater, and reduces the failure occurrence.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of solar water heater, specifically is meant a kind of inflatable emptier.
Technical background
At present, solar water heater has been widely used in the middle of the daily life, also is like this in northern China.But, use solar water heater but to be subjected to the restriction of weather temperature in the north of China's cold, as be installed in outdoor for solar water heater water tank up and down the upper and lower conduit of water be easier to freeze because of it contains water, the application of solar water heater is restricted.In order to solve the problem that upper and lower conduit easily freezes, the outer wall at upper and lower conduit that has increases heat-insulation layer and heater is set, though this kind method has solved the problem of freezing, has increased material cost, and heater also exists potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, can not freeze under any weather condition for the upper and lower conduit of water about the solar water heater water tank and provide a kind of, removing solar water heater and use restricted inflatable emptier.
For achieving the above object, the technical scheme that provides is: the inflatable emptier includes check valve and flexible pipe, is connected with aerating device at check valve one end, and its other end is communicated in upper and lower conduit, upper and lower conduit also is communicated in the flexible pipe that is arranged in the water tank, and the flexible pipe other end is provided with the heavy burden piece.
Described one-way valve structures can be: valve inner is provided with spheroid and spool, and spheroid places on the spool identically, and spheroid and spool are divided into valve pocket and inlet chamber with check valve inside, and valve pocket is communicated in upper and lower conduit, and inlet chamber is communicated in aerating device.
Described aerating device is similar articles such as inflator or air pump.In addition, in aerating device and pipeline that check valve is communicated with, can be provided with unidirectional charge valve.
Because adopt such scheme, flexible pipe one end that has the heavy burden piece can stretch into from the steam vent at water tank upper or top in the water tank, the flexible pipe other end is communicated in upper and lower conduit, and check valve and aerating device then are installed in indoor.In use, inflate to check valve by aerating device, air-flow overcomes the gravity of spheroid and enters valve pocket, the air-flow that enters valve pocket is with in water in it and the water top recovery tank in the upper and lower conduit, final emptying upper and lower conduit, and be unlikely under the lower situation of outdoor temperature, to endure cold, influence the use of solar water heater.When needs hot water, open mixed water valve, utilize siphon principle, flexible pipe will supply to use hot water in the water inspiration upper and lower conduit in the water tank.Therefore, the water intaking in the water tank utilizes siphon principle, and not fragile each parts in the service life that strengthens solar water heater, reduce the generation of fault; And check valve and aerating device are installed in indoor easy to use and installation.Simple in structure, cost is low, use installation and maintenance all very convenient also is the outstanding characteristics of the utility model.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Establish spheroid 7 and spool 8 in the valve body 13 of check valve, spheroid 7 places on the spool 8 identically, spheroid 7 and spool 8 are divided into valve pocket 12 and inlet chamber 9 with check valve inside, spool 8 places on the inwall of inlet chamber 9, valve pocket 12 is communicated in upper and lower conduit 11, inlet chamber 9 is communicated in aerating device 14, aerating device 14 is similar articles such as inflator or air pump, in aerating device 14 and pipeline that inlet chamber 9 is communicated with, be provided with unidirectional charge valve 10, unidirectional charge valve 10 effects are that the air-flow of aerating device can only flow to check valve by single direction, and can not adverse current, unidirectional charge valve 10 can adopt prior art products, replaces as the valve cock on the available tire.The top of upper and lower conduit 11 is connected with flexible pipe 2 by connector 3, be with heavy burden piece 4 on the outer wall of the other end of flexible pipe 2, this end places in the water tank 1 of solar water heater, some will be higher than the height of the water water surface in the water tank flexible pipe 2 in the water tank 1, because of flexible pipe 2 ends are provided with heavy burden piece 4, therefore should can be sunken to water tank bottom by end.The interlude of upper and lower conduit 11 is communicated with running water pipe 6, installs on it and mixes water valve 5.
The utility model is not only limited to the foregoing description, as long as include the technical scheme that aerating device, check valve and flexible pipe constitute, all belongs to protection domain of the present utility model.Simultaneously, the concrete structure of aerating device, check valve also is not limited only to the foregoing description, also can make other form into as spheroid and the spool that cuts off inner two chambers of check valve.
Claims (5)
1, a kind of inflatable emptier that includes check valve and flexible pipe, it is characterized in that also including aerating device, aerating device is communicated in an end of check valve, the other end of check valve is communicated in upper and lower conduit, upper and lower conduit also is communicated in the flexible pipe that is arranged in the water tank, and the flexible pipe other end is provided with the heavy burden piece.
2, inflatable emptier according to claim 1, it is characterized in that described check valve inside is provided with spheroid and spool, spheroid places on the spool identically, and spheroid and spool are divided into valve pocket and inlet chamber with check valve inside, valve pocket is communicated in upper and lower conduit, and inlet chamber is communicated in aerating device.
