Description
Technical field
The invention belongs to the intake and exhaust technical field of warming solar energy water tank, particularly a kind of solar water heater water tank air pressure regulator.
Background technique
Conventional energy resource is deficient in recent years, and this green energy resource of development and utilization solar energy has great significance, and it is that renewable energy sources does not pollute the environment again.Solar water heater is that current people utilize the most general equipment of solar energy, and heat-insulating water tanks is the critical component of solar water heater, and it is the container of stored hot water, and the hot water of gathering through heat collecting pipe stores through heat-insulating water tanks, prevents heat loss.Solar water heater needs often water inlet, draining, for the safety that guarantees water tank with to advance draining unobstructed, on water tank, be provided with the water tank air pressure regulator that is used for the balanced reservoir inner and outer air pressure.Common water tank air pressure regulator is a pipeline, though this kind structure is simple, intake and exhaust are that a passage blocking pipe that freezes occurs easily in winter, can't realize the adjusting of water tank external and internal pressure.
In Chinese patent ZL200920224737, disclose a kind of solar water heater exhaustion valve, its technological scheme is in the inner chamber of outer tube, to be provided with interior pipe, and the external diameter of interior pipe is less than the internal diameter of outer tube; In be connected through connecting plate between the inwall of outer wall and outer tube of pipe, be plugged with middle pipe through interference fit in the interior pipe, the lower end of middle pipe is plugged in interior the pipe; And the lower end at middle pipe is provided with end cap; The center of said end cap is provided with attachment hole, is provided with leakage hole around the attachment hole, and other has discoid middle pipe lid; The center of middle pipe lid is provided with connecting rod, and this connecting rod is plugged in the attachment hole at end cap center; On the outer wall of middle pipe upper end, be set with soft shirt rim, said soft shirt rim is circular, and the inner edge of soft shirt rim is fixedly connected with the outer wall of middle pipe, and the outer rim of soft shirt rim covers the open upper end place of outer tube.This solar water heater exhaustion valve is arranged gas-entered passageway and exhaust passage branch, and compact structure has solved the problem that winter, outlet valve froze well on the basis that does not influence original mounting structure.But this outlet valve is owing to be provided with interior pipe, middle pipe and outer tube, thereby parts are many, and complex structure is not easy to processing, and cost of production is high.
Summary of the invention
In order to overcome the shortcoming that above-mentioned existing technology exists, the object of the present invention is to provide a kind of solar water heater water tank air pressure regulator, this modulating valve, simple in structure, parts are few, are convenient to process and reduce production costs.
In order to address the above problem, the present invention adopts following technological scheme:
A kind of solar water heater water tank air pressure regulator comprises the valve body and the valve cover of tubulose it is characterized in that the binding end of described valve body and valve cover is provided with annular flanging, is interval with a plurality of air flues on the described annular flanging; Described valve cover is the groove of cross section for circle; Horizontal and the valve core plate of interference fit in valve body is connected on the groove inwall of valve cover through riser; Described valve core plate is provided with first one-way valve in the opposite direction and second one-way valve; Described riser is divided into two independently passages between first one-way valve and second one-way valve and with body cavity, on the groove inwall of valve cover, be provided with the annular slot that cooperates with valve body annular flanging.
Described air flue is that three annular flangings are uniformly distributed with.
The equal semicircular in shape structure of described one-way valve; The semicircular structure that is arranged on the valve core plate has two symmetrical valves; On the connecting plate between two valves, be provided with inside or outside axial bore, the elastic valve plate that cooperates with two valves is filled in the axial bore on the described connecting plate through the mount pin of center.
The invention has the beneficial effects as follows:
1, owing to only be provided with a tubular valve body, the cooperation through between riser and first one-way valve, second one-way valve has solved the problem that winter, outlet valve froze, water tank internal and external pressure balance problem well on the basis that does not influence original mounting structure.
2, it is simple in structure, and parts are few, is convenient to process and reduce production costs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explanation:
Fig. 1 is the overall structure sectional view of the embodiment of the invention;
Fig. 2 is spool of the present invention and valve cover structural representation;
Fig. 3 is a valve body structure schematic representation of the present invention.
Among the figure: 1 valve body, 11 flangings, 12 air flues, 2 valve covers, 21 risers, 22 valve core plates, 23 first elastic valve plates, 231 mount pins, 24 second elastic valve plates, 25 annular slots.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; A kind of solar water heater water tank air pressure regulator; The valve body 1 and valve cover 2 that comprise tubulose; Binding end with valve cover on the described valve body 1 is provided with annular flanging 11, is interval with a plurality of air flues 12 on the described annular flanging 11, and the end in addition of valve body 1 is provided with the contraction mouth of pipe.Valve cover 2 is the groove of lateral cross section for circle, and the horizontal and valve core plate 22 of interference fit in valve body is connected through riser 21 on the groove inwall of valve cover 2, the inner wall sealing of valve core plate 22 and valve body 1.
