Abstract
The utility model relates to a solar water heater, in particular to an auxiliary safety valve of the solar water heater, which comprises a valve body one end of which is sealed, wherein an exhaust valve is arranged above the valve body, and an air intake valve is arranged below the valve body. By adopting the structure, the utility model can effectively prevent the solar water heater from bursting because of excessive pressure. Moreover, the utility model has the effect of heat insulation.
Description
Technical field
The utility model relates to a kind of solar water heater, specifically, relates to a kind of solar water heater auxiliary security valve.
Background technique
Along with The development in society and economy, the energy has become the obstacle of restriction economic development, and the solar water appliance has advantages such as energy-saving and environmental protection, has obtained in recent years applying preferably.Traditional individual water heater upper end is typically provided with header tank, be used to store the hot water of heat collecting pipe heating, in order to guarantee the normal water supply of header tank, the header tank upper end will be established a through tube and be communicated with air, heat hydraulic pressure in the header tank can be leaked like this, when preventing the overpressure in the header tank, make heat collecting pipe and header tank explosion.But traditional through tube that communicates with header tank is uncovered, causes the header tank heat to run off, and has wasted the energy.
The model utility content
The utility model has overcome shortcoming of the prior art, and a kind of solar water heater auxiliary security valve is provided, can be effectively explosion-proof, and make the solar water heater safe handling, and have characteristics such as simple in structure, low cost of manufacture.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of solar water heater auxiliary security valve comprises the valve body that an end seals, and described valve body top is provided with outlet valve, and this valve body below is provided with suction valve.
Further, described outlet valve is one vertically up, and the body of upper end closed, its sidewall is provided with at least one exhaust port, and this body bottom is a through hole that is connected with above-mentioned valve body, and a spheroid is arranged in this body, its diameter is greater than this through hole, and can move up and down in this body.
Further, described through hole is a round table-like through hole wide at the top and narrow at the bottom, and above-mentioned sphere diameter is greater than the narrow limit of above-mentioned round table-like through hole.
Further, described suction valve be one vertically down and the bottom be provided with the body of inlet hole, a spheroid is arranged in this body, its diameter is greater than the diameter of above-mentioned inlet hole, this body top is provided with the block that stops this spheroid to enter above-mentioned valve body.
Further, described valve body closed end is a removable end cap.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts this structure, can effectively prevent solar water heater because of the excessive explosion of pressure, and have heat insulation effect.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the sectional view of solar water heater auxiliary security valve.
Embodiment
As shown in Figure 1, solar water heater auxiliary security valve described in the utility model comprises the valve body 1 that an end seals, and valve body 1 closed end is removable end cap 11, and valve body 1 top is provided with outlet valve 2, and valve body 1 below is provided with suction valve 3.
In the present embodiment, outlet valve 2 is one vertically up, and the body of upper end closed, its sidewall is provided with four exhaust ports 21, this body bottom is the round table-like through hole 22 wide at the top and narrow at the bottom that is connected with valve body 1, spheroid 23 diameters are greater than round table-like through hole 22 narrow limits, and can move up and down in this body.
When the temperature of water or water reached more than 95 ℃ on the solar water heater, spheroid 23 was by steam jack-up, and outlet valve 2 is from exhaust port 21 exhaust steams, and spheroid 23 is blocked the narrow limit of round table-like through hole 22 under static situation, made outlet valve 2 sealings.
Solar water heater is when discharging water, and the spheroid 32 of suction valve 3 scrolls up, and air enters from inlet hole 31, and when static, spheroid 32 is blocked inlet hole 31, makes suction valve 3 sealings.
The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
