Abstract
The invention provides a heat-preserving water tank for a solar water heater. The water tank comprises a water tank body, a water inlet pipe and a water outlet pipe, wherein the water tank body is provided with a pressure limiting valve for exhausting air. In the heat-preserving water tank for the solar water heater of the invention, the water tank is provided with the pressure limiting valve and the opening and closing of the pressure limiting valve are controlled through pressure intensity in the water tank, so that the temperature of the water tank is controlled. When the temperature of the water tank and the pressure intensity are low, the pressure limiting valve is kept closed, so that heat loss caused by leakage of hot steam is prevented; and when the temperature of the water tank surpasses a preset value, the pressure limiting valve is opened under the action of pressure in the water tank and redundant hot air is exhausted, so that damage to the water tank caused by excessively high pressure intensity in the water tank is prevented and the aims of heat preservation and overpressure protection are fulfilled.
Description
Technical field
The present invention relates to a kind of parts of solar water heater.
Background technology
Solar energy is as a kind of new forms of energy, and is inexhaustible; Simultaneously because solar energy is a kind of energy of cleaning, when development and use, can produce waste residue, waste water, waste gas, not have a noise yet; More can not influence the ecological balance; Can never pollute and public hazards,, widely favored by people therefore in today that height is advocated environmental protection.The most common solar energy development utilization is exactly a solar water heater, and especially in vast rural area, solar energy has got into huge numbers of families as a kind of water heater of energy-conserving and environment-protective.Its cardinal principle is to utilize gatherer to convert sunlight collection into heat energy, and the water heating is stored in the attemperater, and is for people to use.For the overvoltage protection of attemperater, water tank is provided with venthole, is used to prevent that the water tank internal gas pressure is too high and cause the damage to water tank.But,, make when temperature is higher than the atmospheric temperature outside the water tank in water tank that the hot water and steam in the water tank will exclude pore owing to be provided with venthole on the water tank, thereby cause heat to run off that heat insulation effect weakens.Especially in winter, under the light application time condition of limited, the heat that causes of steam vent runs off comparatively obvious to the insulation effect influence of water tank.
To above-mentioned deficiency, need to explore a kind of new attemperater, when water tank is played overvoltage protection, also can prevent the unnecessary loss of heat, play insulation effect preferably.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of heat-preserving water tank for solar water heater, when water tank is played overvoltage protection, also can prevent the unnecessary loss of heat, play insulation effect preferably.
The objective of the invention is to realize through following technical scheme: a kind of heat-preserving water tank for solar water heater, comprise tank body, water inlet pipe and outlet pipe, tank body is provided with the pressure limiting valve that is used for exhaust.
Further, also comprise blast pipe, blast pipe is arranged on the tank body with the mode of passing the tank body bottom, and the upper end of blast pipe is near the tank body top inner wall, and pressure limiting valve is connected with the blast pipe lower end;
Further, said pressure limiting valve is a check valve;
Further, said check valve comprise cylindrical shell, and the cylinder inboard wall sealed sliding movingly piston and be connected cylindrical shell bottom and piston between spring, cylindrical shell is provided with steam vent near the barrel of its bottom one end.
The invention has the beneficial effects as follows: heat-preserving water tank for solar water heater of the present invention; Owing on water tank, be provided with pressure limiting valve, control the switching of pressure limiting valve through pressure in the water tank, thereby control water tank temperature; When water tank temperature less; Pressure hour, pressure limiting valve keeps shut, and prevents that the outflow of vapours from causing thermal loss; When water tank temperature surpassed predetermined value, pressure limiting valve was washed open under the effect of water tank internal pressure, lays down unnecessary hot gas, prevents that the water tank too high pressure from causing the destruction to water tank, played the purpose of insulation and overvoltage protection simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the A portion enlarged drawing among Fig. 1.
The specific embodiment
Accompanying drawing 1 is a structural representation of the present invention; Accompanying drawing 2 is the A portion enlarged drawing among Fig. 1.As shown in the figure, a kind of heat-preserving water tank for solar water heater comprises tank body 1, water inlet pipe 2 and outlet pipe 3, and tank body is provided with the pressure limiting valve that is used for exhaust.Control the switching of pressure limiting valve through pressure in the water tank, thus the control water tank temperature, when water tank temperature less, pressure hour, pressure limiting valve keeps shut, and prevents that the outflow of vapours from causing thermal loss; When water tank temperature surpassed predetermined value, pressure limiting valve was washed open under the effect of water tank internal pressure, lays down unnecessary hot gas, prevents that the water tank too high pressure from causing the destruction to water tank, played the purpose of insulation and overvoltage protection simultaneously.
In the present embodiment, also comprise blast pipe 4, blast pipe is arranged on the tank body with the mode of passing tank body 1 bottom, and the upper end of blast pipe is near the tank body top inner wall, and pressure limiting valve is connected with blast pipe 4 lower ends.Through blast pipe pressure limiting valve is arranged on the bottom of tank body 1, prevents that foreign material etc. from falling into blast pipe, simultaneously, good looking appearance is generous.
In the present embodiment, said pressure limiting valve is a check valve.Adopt check valve control air pressure, simple in structure, easily manufactured, with low cost.
In the present embodiment, said check valve comprise cylindrical shell 5, and the cylinder inboard wall sealed sliding movingly piston 6 and be connected cylindrical shell bottom and piston between spring 7, cylindrical shell is provided with steam vent 8 near the barrel of its bottom one end.During use, temperature is too high in tank body, and present embodiment exceeds with 85 ℃; When temperature in the tank body surpassed 85 ℃, the pressure in the tank body was higher, and piston 6 is produced downward thrust; When piston slides into steam vent when following; Pneumatic pipe cleaner in the tank body is crossed steam vent and is discharged, and makes the interior pressure of tank body reduce gradually, reaches the purpose of overvoltage protection.Simultaneously, the thrust of piston 6 is also reduced gradually, piston resets under the effect of spring gradually, and vent closure stops the continuation of vapours in the tank body to be scattered and disappeared, play insulation about.Check valve adopts piston structure to seal, and air-tightness is good, is difficult for gas leakage; Simultaneously, adopt spring that piston is controlled, can be according to the stressing conditions of different temperatures lower piston; Select the spring of different coefficient of elasticity, temperature and pressure with in the control tank body control very convenient.Through repetition test, handling strong, high insulating effect.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the power claimed range of the present invention.
