Description
Technical field
The utility model relates to technical field of solar water heaters, particularly relates to a kind of exhaust backwater structure for solar water heater.
Background technique
Existing solar water container exhaust backwater structure is by a zinc-plated tee union connection suitable for reading air exhaust rod always, end opening with connect tooth head return pipe soon and connect and compose, the backwater exhaust structure of such Placement composition exists installs comparatively complexity, and longer shortcoming consuming time is installed, there is etching problem in zinc-plated tee union simultaneously, can affect the exhaust effect of water tank during corrosion transition.When user's water, venting gas appliance can become suction means, and (tonifying Qi in feed tank prevents from forming negative pressure, water tank inhaled flat), can be drawn onto in water tank the corrosion impurity of zinc-plated three Tonglis during air-breathing, polluted water, thus the health of harm people.
Model utility content
The utility model object provides a kind of convenient installation to overcome the deficiencies in the prior art, install laborsaving, and cost is low, the exhaust backwater structure that outdoor antiseptic power is strong simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of exhaust backwater structure, comprises internal thread tee union, outer silk water is chewed, outlet pipe, seal ring, nut cap and return pipe; The material of described internal thread tee union is brass; Described internal thread tee union is chewed with outer silk water and is connected; On described internal thread tee union, interface is connected with outlet pipe; Described internal thread tee union lower interface is provided with seal ring; Described internal thread threeway lower interface is connected with return pipe by nut cap.
Preferably, the material of described outlet pipe is plastic water pipe.
Preferably, described internal thread tee union is chewed internal thread with outer silk water and is connected.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages: the exhaust backwater structure of the utility model scheme, its exhaust return water mode is simple and practical, and can the installation time be saved, outdoor anti-corrosive properties also substantially increase, smooth in exhaust, water quality safety when ensure that air-breathing in water tank, meets the actual demand of each side.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further.
Accompanying drawing 1 is the three-dimensional exploded view of the utility model exhaust backwater structure.
Structural representation after the installation that accompanying drawing 2 is the utility model exhaust backwater structure.
Wherein: 1, internal thread tee union; 2, outer silk water is chewed; 3, outlet pipe; 4, seal ring; 5, nut cap; 6, return pipe.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
One exhaust backwater structure described in the utility model as shown in accompanying drawing 1-2, comprises internal thread tee union 1, outer silk water chews 2, outlet pipe 3, seal ring 4, nut cap 5 and return pipe 6; The material of described internal thread tee union 1 is brass; Described internal thread tee union 1 is chewed 2 with outer silk water and is connected; On described internal thread tee union 1, interface is connected with outlet pipe 3; Described internal thread tee union 1 lower interface is provided with seal ring 4; Described internal thread threeway 1 lower interface is connected with return pipe 6 by nut cap 5; The material of described outlet pipe 3 is plastic water pipe; Described internal thread tee union 1 is chewed 2 internal threads with outer silk water and is connected.
One exhaust backwater structure described in the utility model as shown in accompanying drawing 1-2, during use, first internal thread tee union is arranged on outer silk water to chew, its Placement is that internal thread connects, then the upper interface of internal thread tee union is directly connected with outlet pipe, then nut cap is enclosed within return pipe, return pipe puts the lower interface of the internal thread tee union that seal ring is housed, tightening nuts lid, the lower interface of such internal thread tee union is just interconnected with return pipe, finally defines an exhaust backwater structure.
Exhaust backwater structure of the present utility model, its exhaust return water mode is simple and practical, and can save the installation time, outdoor anti-corrosive properties also substantially increase, smooth in exhaust, and water quality safety when ensure that air-breathing in water tank, meets the actual demand of each side.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
