Description
Technical field
The present invention relates to technical field of solar, relate in particular to a kind of pipe line evacuation valve that can be used on the solar energy water heater pipe.
Background technique
Solar energy is as a kind of green energy resource, and is never exhausted, pollution-free with it, is not subjected to advantages such as region restriction, is subject to people's attention.Heliotechnics is obtaining promotion and application rapidly.
Therefore plurality of advantages such as the solar water appliance has environmental protection and energy saving, and is easy to use, safe, become the first-selection that people install water heater.
At present, the method for operation of present most pipeline emptying valve for solar water heater is to realize by the switch of water about switching and exhaust duct.When pipeline communicated with atmosphere, the water in the pipeline was discharged from the bottom by action of gravity, reaches air emptying function.But in the existing emptying mode, the exhaust-valve side that has is installed in the right side thermal insulation layer of water-heater water tank, though the energy heat insulation protecting can prevent that freezing of valve and pipeline is stifled, processing is too complicated, and postorder also is inconvenient to keep in repair; The emptier that has is directly exposed to external environment condition, though can accomplish easy to maintenancely, thermal insulation property is poor, freezes stifledly easily at the water fittings place, thereby some producer increases electric heating wire etc. on exhaust-valve, cause and leak or leaky; Even have have winter the time after water vapour sheds, condense in the outlet port, it is stifled to cause rising pipe to freeze, and finally causes air emptying function to lose efficacy.
Therefore, how to develop a kind of simple in structure, easy to maintenance, pipe line evacuation valve, become the present technical issues that need to address of those skilled in the art with emptying and preventing freeze in winter plugging function.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to maintenance, pipe line evacuation valve with emptying and preventing freeze in winter plugging function.
For solving the problems of the technologies described above, the invention provides a kind of pipe line evacuation valve, comprise valve body, described valve body top is provided with paddle hole, the below is provided with the turnover water nozzle, also comprises final controlling element, live axle, valve block support, rotates valve block; Described final controlling element is connected with described valve body by the fastening Elastic buckle of no screw, live axle inserts the output gear hole of described final controlling element, have two fixing rods to insert the fixed hole of described final controlling element on the described valve body in addition, described valve block support and described rotation valve block are located between described valve body and the described final controlling element; Described valve body top also is provided with the emptying tracheae.
Preferably, also be provided with seal ring between described valve body and the described rotation valve block.
The keying of pipe line evacuation valve provided by the invention is to realize by the rotation of rotating valve block: gas circuit is positioned at water-heater water tank inside, rotate the hole that communicates with upper and lower conduit road and emptying tracheae difference (but not simultaneously) is arranged on the valve block, to rotate after valve block rotates to an angle, the one hole communicates with the upper and lower conduit road on the rotation valve block, and another hole and emptying tracheae are obstructed; Rotate to an angle, a hole of rotating on the valve block communicates with the emptying tracheae again, and another Kong Zeyu upper and lower conduit road is obstructed.Utilize the final controlling element of band turbine and worm to start the rotation valve block, with the switch of this rotation transformation pipeline, the switch of valve is implemented by the final controlling element of band drive structure of gear worm, realizes the water up and down of water heater and the emptying of pipeline.
The present invention adopts valve body, final controlling element combination, direct built-in down inserting type is installed on the water tank liner, makes emptier and water heater form an integral body, and workshop processing is simple, and installation and maintenance are also convenient, make full use of the thermal insulation layer of water-heater water tank, effectively be incubated, utilize interposed structure down simultaneously, steam is difficult for getting rid of downwards, exhaust ports is avoided steam to condense to form in exhaust ports and is frozen stifledly in thermal insulation layer, has overcome hidden danger and drawback that existing exhaust-valve exists.
This pipe line evacuation valve pipeline connects simple and convenient, and the pipe that links to each other with atmosphere is difficult for freezing stifled, uses simple to operate etc.

Embodiment
Core of the present invention provides a kind of simple in structure, easy to maintenance, pipe line evacuation valve with emptying and preventing freeze in winter plugging function.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Please refer to Fig. 1-Fig. 3, Fig. 1 is the structure composition frame chart of a kind of embodiment of pipe line evacuation valve provided by the present invention, and Fig. 2 is the side-looking structural representation of pipe line evacuation valve among Fig. 1, and Fig. 3 is the decomposition texture schematic representation of pipe line evacuation valve among Fig. 1.
As shown in Figure 1-Figure 3, pipe line evacuation valve provided by the invention comprises valve body 3, valve body 3 tops are provided with paddle hole 2, the below is provided with turnover water nozzle 4, also comprise final controlling element 5, live axle 9, valve block support 8, the ceramic valve plate 7 of being with drive structure of gear worm, wherein, final controlling element 5 is fixedlyed connected with valve body 3 by the fastening Elastic buckle 10 of no screw, can also be manually under need not be by the situation of instrument final controlling element 5 be separated with valve body 3; The output gear hole that live axle 9 inserts final controlling element 5 has two fixing rods to insert the fixed hole of final controlling element 5 in addition on the valve body 3, valve block support 8 and ceramic valve plate 7 are located between valve body 3 and the final controlling element 5; Valve body 3 tops also are provided with emptying tracheae 1; Be provided with silica gel O shape circle 6 between valve body 3 and the ceramic valve plate 7, ceramic valve plate 7 is combined closely with silica gel O shape circle 6, to reach the effect of sealing, as shown in Figure 3.
Emptying tracheae 1 directly exceeds the full water plane, communicates with atmosphere, and the opening of final controlling element 5 control valves closed and made water flow into or flow out from paddle hole 2, and is connected with pipeline by turnover water nozzle 4, feeds indoor.
During use, by the final controlling element 5 rotary ceramic valve blocks 7 of band drive structure of gear worm, when the hole on the ceramic valve plate 7 communicated with the upper and lower conduit road, another hole and breathing pipe were obstructed, realized the water up and down of hot water tank 11 with this.
When the hole on the ceramic valve plate 7 communicated with breathing pipe, another hole and upper and lower conduit road were obstructed, realize the function of emptying with this.Rotate ceramic valve plate 7 by live axle 9 and valve block support 8, switch valve state between water flowing and ventilation emptying, simple and easy to use.
