Abstract
The utility model discloses a non-return switch valve for the pipeline of a solar water heater. The non-return switch valve comprises a valve body, wherein a non-return valve core and a switch valve core are arranged in the valve body; the non-return valve core is arranged on one side of the switch valve core, and comprises a guide sleeve; a trapezoid seal ring is arranged in the guide sleeve; a slip sheet is arranged at one end of the trapezoid seal ring; the other end of the trapezoid seal ring is connected with a flat end surface in the cavity of the valve body; the switch valve core comprises a sphere arranged in the valve body; the sphere is connected with a valve rod and is connected with the valve body through a sealing ring; the valve rod is connected with a handle; the guide sleeve is connected with the valve body through threads; a sealing gasket is arranged at the end of the guide sleeve connected with the switch valve core; and filter screens are arranged at two ends of the valve body. As the non-return performance and the on-off function are integrated in the non-return switch valve, the non-return switch valve provided by the utility model can not only prevent hot water from flowing back, but also realize the on-off function, which not only reduces the product cost, but also simplifies the structure, and facilitates the mounting and the maintenance.
Description
Technical field
The utility model relates to a kind of water heater function accessory, especially a kind of pipelines of solar water heater non-return switch valve.
Background technique
At present, when the solar water heater interior conduit is installed, for the Security that guarantees solar energy system be convenient to keep in repair, all need to install switch valve at the cold water feed-water end.In addition, reflux, also need safety check be installed at the cold water feed-water end in order to prevent hot water.In realizing process of the present utility model, model utility people finds that there is following problem at least in prior art: when mounted valve, two valves all need to carry out assembled on site, and all are furnished with filter screen, cause inconvenience, higher, the filtering function repetition of cost are installed.
The model utility content
The utility model embodiment's purpose is the defective at above-mentioned prior art, provides a kind of simple in structure, and is easy for installation and be convenient to maintenance, both can prevent that hot water from refluxing, and can realize opening and closing the pipelines of solar water heater non-return switch valve of function again.
The technological scheme taked of the utility model is to achieve these goals: a kind of pipelines of solar water heater non-return switch valve, comprise valve body, be provided with non-return valve core and switch spool in the described valve body, described non-return valve core is arranged on a side of described switch spool, described non-return valve core comprises guide sleeve, be provided with trapezoidal seal ring in the described guide sleeve, described trapezoidal seal ring one end is provided with slide plate, and the other end connects planar end surface in the described valve body chamber; Described switch spool comprises the spheroid that is arranged in the valve body, and described spheroid connects valve rod.
Described valve rod connects handle.
Described spheroid connects valve body by seal ring.
Described guide sleeve is by the valve body that is threaded.
The end that described guide sleeve is connected with the switch spool is provided with sealing gasket.
Described valve body two ends are provided with filter screen.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is: the utility model is integrated in non-return performance and keying function on the valve, can prevent that hot water from refluxing, and can realize the keying effect, not only reduced product cost, and simple in structure, easy for installation and be convenient to the maintenance.
Description of drawings
Fig. 1 is the structural representation of the pipelines of solar water heater non-return switch valve that provides among the utility model embodiment.
Among the figure: 1 valve body, 2 filter screens, 3 guide sleeves, 4 slide plates, 5 trapezoidal seal rings, 6 sealing gaskets, 7 valve rods, 8 handles, 9 seal rings, 10 spheroids.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, the utility model mode of execution is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of pipelines of solar water heater non-return switch valve, comprise valve body 1, be provided with non-return valve core and switch spool in the valve body 1, described non-return valve core is arranged on a side of described switch spool, and non-return valve core comprises guide sleeve 3, is provided with trapezoidal seal ring 5 in the guide sleeve 3, trapezoidal seal ring 5 one ends are provided with slide plate 4, and the other end connects planar end surface in valve body 1 chamber; Described switch spool comprises the spheroid 10 that is arranged in the valve body 1, and spheroid 10 connects valve rod 7.
The utility model non-return valve core can prevent that hot water from refluxing, thereby avoids hot water to scorch cold water pipe.The utility model is integrated in non-return and two kinds of functions of keying on the valve, has reduced product cost, and has installed more convenient.
Further, be convenient to open and close for the switch spool, valve rod 7 connects handle 8, and switch valve drives valve rod 7 rotations by handle 8 and realizes opening and closing function.
Further, reach better sealing effect in order to make switch valve, spheroid 10 connects valve body 1 by seal ring 9.
Further, connect for convenience, guide sleeve 3 is by the valve body 1 that is threaded.
Further, in order to reach better sealing effect, the end that guide sleeve 3 is connected with the switch spool is provided with sealing gasket 6.
Further, in order to reach the purpose of impurity screening, valve body 1 two ends are provided with filter screen 2.
The utility model is installed in the water inlet initial end of cold water pipeline in use, and cold water at first enters switch spool one end, the non-return valve core of flowing through then.Drive valve rod 7 by handle 8, valve rod 7 drives spheroid 10 rotations and realizes opening and closing function, and the switch spool can guarantee the Security of solar water heater system and be convenient to maintenance; Under normal use condition, during the unexpected stop supplies of cold water, non-return valve core can prevent that hot water from refluxing, and non-return valve core is realized the non-return performance by the face seal of planar end surface in trapezoidal seal ring 5 end faces in the slide plate 4 and valve body 1 chamber, thereby avoids the hot water backflow and scorch cold water pipe.When mounted, non-return switch valve two ends all will install filter screen 2 additional, reach the purpose of impurity screening.This non-return switch valve is integrated in non-return performance and keying function on the valve, has not only reduced product cost, and has installed more convenient.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
