Abstract
The utility model discloses a safe and reliable solar water heater with an escape valve and a good heat preservation effect. The solar water heater comprises a water storage tank, a plurality of vacuum tubes and an escape valve, wherein the vacuum tubes are connected with the lower portion of the water storage tank, the escape valve is arranged at the upper portion of the water storage tank, and the escape comprises a connecting pipe, a ring-shaped boss, a bonnet and a vent hole. The ring-shaped boss is arranged on the intermediate portion of the connecting pipe, the bonnet is arranged at the upper end of the connecting pipe, and the lower portion of the bonnet is connected with the pipe periphery which is provided with the vent hole. A spool which has a sealed upper end and a vent hole in the middle is arranged inside of the connecting pipe. The outside dimension of the spool is engaged with the inside diameter dimension of the connecting pipe where the spool is arranged, and the spool is arranged at the lower portion of the vent hole of the connecting pipe without the external force action. The utility model is applied to solar water heaters.
Description
Technical field
The utility model relates to a kind of solar water heater, relates in particular to a kind of solar water heater that has safety valve.
Background technology
Development along with society, the particularly develop rapidly of industrial economy, the energy has become a big obstacle of restriction economic development, while is along with the raising of people's quality of life, environmental protection is had higher requirement, and environmental issue has become the hot issue of people's common concern, so entire society advocates comprehensive utilization of energy and carries out environment-friendly engineering, because the solar water appliance has environmental protection, advantage such as energy-conservation, so obtained in recent years applying quickly.In solar water heater, safety and insulation problem are problems that needs draw attention, and safety is relevant with storage tank with the insulation problem, the major function of storage tank is water storage and insulation effect, pressure in the storage tank can increase along with the rising of water temperature, thereby on storage tank, need stay passage, but to evening, because water temperature no longer raises, so just not needing to recur, this passage do not regulate the effect of pressure, opposite, because the effect of passage, storage tank is connected with outside air, thereby causes the reduction of water temperature, so in order to help the insulation of storage tank more, preferably passage temporarily can be sealed, and storage tank generally all is installed in the higher position, and this gives in the operation and makes troubles, and also has certain potential safety hazard simultaneously.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of solar water heater that has safety valve of safe and reliable, high insulating effect.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises storage tank, some vacuum tubes that are connected with the storage tank below, described storage tank top also is provided with safety valve, described safety valve comprises tube connector, described tube connector interlude is provided with ring-like boss, described tube connector upper end is provided with bonnet, described bonnet below tube connector periphery is provided with passage, be provided with upper end closed and the middle spool that has passage in the described tube connector, the tube connector internal diameter size of the outside dimension of described spool and its present position is suitable, described spool be under the no external force effect tube connector passage below.
As preferably, the below tube connector periphery of described tube connector passage also is provided with tapered boss.
The utility model adopts the safety valve of the spool that has passage, spool is risen, passage on the spool is connected with passage on the tube connector, thereby reach the effect of pressure regulation, and when air pressure descends, spool sinks storage tank and outside air are isolated automatically, thus not only safe and reliable, and high insulating effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of safety valve among Fig. 1;
Fig. 3 is the profilograph of Fig. 2;
Fig. 4 is the structural representation of the spool among Fig. 3.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in Figure 1, the utility model comprises storage tank 1, some the vacuum tubes 2 that are connected with storage tank 1 below, and storage tank 1 top also is provided with safety valve 3.
Extremely shown in Figure 4 as Fig. 2, safety valve 3 comprises tube connector 4, tube connector 4 interludes are provided with ring-like boss 5, when tube connector 1 is installed on the storage tank 1, ring-like boss 5 can be stuck in storage tank 1 junction, tube connector 4 upper ends are provided with bonnet 6, the effect of bonnet 6 is to prevent that rainwater from entering in the tube connector 4, tube connector 4 peripheries are provided with passage 7 below bonnet 6, be provided with upper end closed and the middle spool 9 that has passage 8 in the tube connector 4, the internal diameter size of the outside dimension of spool 9 and the tube connector of its present position 4 is suitable, spool 9 be under the no external force effect tube connector 4 passages 7 below, make in the storage tank 1 to be isolated, thereby play insulation effect with outside air; And rise to when being enough to make spool 9 to rise to make its passage 8 and passage 7 on the tube connector 4 being connected when storage tank 1 internal gas pressure, make in the storage tank 1 and be connected with outside air, thereby play the effect of pressure regulation, and when air pressure descends, 9 of spools sink to the lower position that is lower than tube connector 4 passages 7 automatically, storage tank 1 and outside air are isolated, thereby play heat insulation effect preferably; Tube connector 4 peripheries also are provided with tapered boss 10 below tube connector 4 passages 7, the setting of tapered boss 10, make hot gas following unlikely interface that flows to tube connector 4 and storage tank 1 after being condensed into the globule of discharging from passage 7, interior and heat-insulation layer is caused damage thereby condensed water can not penetrate into heat-insulation layer.
Claims (2)
1. solar water heater that has safety valve, comprise storage tank, some vacuum tubes that are connected with the storage tank below, described storage tank top also is provided with safety valve, described safety valve comprises tube connector, described tube connector interlude is provided with ring-like boss, it is characterized in that described tube connector upper end is provided with bonnet, described bonnet below tube connector periphery is provided with passage, be provided with upper end closed and the middle spool that has passage in the described tube connector, the tube connector internal diameter size of the outside dimension of described spool and its present position is suitable, described spool be under the no external force effect tube connector passage below.
