Abstract
The invention relates to a blast and vacuum prevention self-detaching safety valve for solar energy water heater, which belongs to the technical field of solar energy water heater. The invention comprises two column shaped pipelines, a round drum shaped pipeline positioned between a round pipeline at two ends and communicated with two round pipelines, as well as a spherical ball with less specific gravity than water being positioned inside the round drum shaped pipeline and can move inside the pipeline. Wherein, an upper end port in the round column shaped pipeline is configured as the overflow port or air inlet port or air outlet port for the safety valve; a lower end port in the round column shaped pipeline is configured as the water outlet port or air inlet port or air outlet port for the safety valve; a plurality of bordering gaps are made on the internal wall at the interface of the round column shaped pipeline connected with the round drum. Therefore, the invention, which can be applied to ensure the safe application of solar energy water heater, has the advantages of simple structure, low cost and easy realization.
Description
Technical field
The invention belongs to the solar water heater field, explosion-proof, the anti-vacuum that particularly is used for solar water heater is explained the valve design by oneself.
Background technique
The solar water heater of current energy-saving and environmental protection more and more is subjected to extensive concern, but can not in time supply water when in actual use, the tank of solar water heater the too high blast of hydraulic pressure often takes place or uses hot water and produce vacuum and make interior bucket (container) be taken out safety problems such as flat.The existing replenisher tank that uses solves vacuum problem, but replenisher tank itself also has anti-vacuum, antifreeze, heat radiation and causes problem such as outward appearance burden.The blast problem is existing uses explosion-proof valve, though solved explosion-proofly, prevents that problems such as vacuum, antifreeze, heat radiation can't solve.This this problem has hindered further promoting the use of of solar water heater.
Summary of the invention
The objective of the invention is for solving the safety problem of above-mentioned use solar water heater, design a kind of explosion-proof, anti-vacuum that is used for solar water heater and explain safety valve by oneself, solar water heater can be used safely, and have simple in structure, cost is low, realizes characteristics such as easy.
Explosion-proof, the anti-vacuum that is used for solar water heater that the present invention proposes is explained safety valve by oneself, comprise two cylindrical pipes, place between this two ends circular pipe and the circle drum pipeline that is connected with two circular pipes, and in placing this circle drum pipeline one can be in pipeline movable proportion be lighter than the ball of water; Wherein the upper end-hole of this cylindrical pipe is the spilling water or the air inlet/outlet of safety valve, and the lower end mouth of cylindrical pipe is the water outlet or the air inlet/outlet of safety valve; The inwall of the jointing of the waterexit end cylindrical pipe that links to each other with the circle drum has a plurality of contract mouths; When hydraulic pressure was too high, this ball distortion entered pipeline until ejection.
Slit between described ball and the circle drum inner-walls of duct can be in 2-5 millimeter scope.
Described ball can adopt proportion be lighter than water rubber material make.
The diameter of described two cylindrical pipes can be identical, and the diameter of ball is about 1-2 a times of cylindrical pipe diameter.
Characteristics of the present invention and effect:
When safety valve of the present invention was not expired at tank water, air-flow can overflow by the contract mouth of safety valve or ball jack-up be overflowed in the container.After water was full, water up to circle drum top, was sealed the water route with ball jack-up, reached purpose antifreeze, insulation.If hydraulic pressure is too high, then the ball distortion enters pipeline until ejection, reaches explosion-proof purpose.When using hot water, drawdown produces vacuum, and at this moment, ball drops to the bottom, and air enters container through the contract mouth, and vacuum problem automatically terminates.

Embodiment
Explosion-proof, the anti-vacuum that is used for solar water heater that the present invention proposes is explained valve by oneself and is reached embodiment in conjunction with the accompanying drawings and be described in detail as follows:
The safety valve structure of the present invention's design as shown in Figure 1, 2, 3.Comprise two cylindrical pipes 11,12, place between this two ends circular pipe and the circle drum pipeline 13 that is connected with two circular pipes, and in placing these circle drum 13 pipelines one can be in pipeline movable proportion be lighter than the ball 14 of water; Wherein the upper end-hole of this cylindrical pipe 11 is the spilling water or the air inlet/outlet of safety valve, and the lower end mouth of cylindrical pipe 12 is the water outlet or the air inlet/outlet of safety valve; The inwall of the jointing of the waterexit end cylindrical pipe 12 that links to each other with circle drum 13 has a plurality of contract mouths 15; Present embodiment is four contract mouths, as shown in Figure 2.
Slit between ball 14 and circle drum pipeline 13 inwalls can be in 2-5 millimeter scope (slit is 3 millimeters in the present embodiment), and ball 14 can be made with the materials such as certain degree of hardness and flexible rubber that have that proportion is lighter than water.
The diameter of two cylindrical pipes is identical, and the diameter of ball 14 is 1-2 times (present embodiment is about about 1.3 times) of cylindrical pipe diameter;
The slits of the size of the size of ball, pipeline material, circle drum, ball and circle drum etc., the especially material of ball, relevant with explosion-proof pressure, different materials and size thereof, explosion-proof pressure have difference, can carry out specific design according to practical application.
Safety valve working process of the present invention is: choosing will be cylindrical be made two-part with the longitudinal axis or transverse axis with the circle drum pipeline, the ball of making is placed in the circle drum pipeline, at last two-part pipeline is integral with the flange connection or with screw screwed connection or adhesive bond, sealed again and got final product, certainly do not limit above-mentioned making step yet, all can as long as ball is put in the ducted any production method of cydariform.
The method that is connected of the water inlet of safety valve or inlet end and tank can be welding, also can be with screw screw thread or bonding.
Working principle of the present invention:
Safety valve of the present invention is installed on the tank.When the container water-filling, when water was not expired, air-flow can overflow by the contract mouth of safety valve or ball jack-up be overflowed in the container, shown in Fig. 1,3.After water was full, water up to circle drum top, was sealed the water route with ball jack-up, as shown in Figure 4, reached purpose antifreeze, insulation.If hydraulic pressure is too high, then the ball distortion enters pipeline until ejection, reaches explosion-proof purpose.
When using hot water, drawdown produces vacuum in the tank, and at this moment, ball drops to the bottom, and air enters container by the contract mouth, and vacuum problem automatically terminates.
