Abstract
The utility model discloses the built-in water by-pass valve body of a kind of forward type, comprise heating termination, the water outlet termination be communicated with heat exchanger, by-passing valve; Be communicated with intake tunnel between described heating termination and by-passing valve, between described by-passing valve and water outlet termination, be communicated with exhalant canal.Described intake tunnel becomes 20-45 degree to be obliquely installed with horizontal plane.How the utility model can solve is more greatly to make its technical problem importing to by-passing valve at heating end pressure.
Description
Technical field
The utility model relates to the water route module in a kind of wall-hung boiler system, mainly refers to the built-in water by-pass module of a kind of self be applied in the module of water route.
Background technology
Water route module or to claim water route integrated be key components and parts in wall-hung boiler internal watercourses system, its effect is integrated in one by flow pipe, and integrate the functions such as water route switching, moisturizing, bathroom water inlet circulation detection.General with multiple interfaces such as water circulating pump, safety valve, temperature sensor, pressure sensor, expansion tanks in the module of water route.The principle of water route module is: by the connection with bathroom heat exchanger and external heat sink, wall-hung boiler water route is divided into heating heat cycles and bathroom heat cycles, and carries out switching between two circulation waterways according to user's behaviour in service.Existing water by-pass module is typically employed in outside and connects the mode adding bypass pipe, adopts the manufacturing cost not only considerably increasing water route module in this way, and increases the condition of External leakage.
Chinese Patent Application No. 201220347681.5 discloses the built-in water by-pass module of a kind of self, it has a water inlet end and two water sides also have a by-passing valve simultaneously, one of them water side is communicated with the equipment such as radiator, referred to here as the first water side, another water side is communicated with plate type heat exchanger, referred to here as the second water side, by-passing valve is connected between main exchange cycles hot water water inlet end and that water side be communicated with plate type heat exchanger, water side below main exchange cycles hot water water inlet end is also referred to as heating end, this heating end is mainly communicated with such as radiator etc., when heating end is closed, and the outside radiator valve be connected is when closing simultaneously, when the water of this inside no longer flows and heating end is heated, water in heating end will expanded by heating, cause being in the motor that heating rectifies top and just cannot open the valve being positioned at heating end, namely this valve cannot be driven down to move thus the hydraulic pressure of heating end is derived from by-passing valve, the larger potential safety hazard of such generation, meanwhile, the design of above-mentioned by-passing valve is mainly fitted on metope, namely with plate type heat exchanger in the same side, when it is time for repair, need whole water route module to take off, thus bring more inconvenience to maintenance and installation.
Utility model content
The purpose of this utility model is to provide the built-in water by-pass valve body of a kind of forward type, and how solve is more greatly to make its technical problem importing to by-passing valve at heating end pressure.
The built-in water by-pass valve body of forward type, comprises heating termination, the water outlet termination be communicated with heat exchanger, by-passing valve; Be communicated with intake tunnel between described heating termination and by-passing valve, between described by-passing valve and water outlet termination, be communicated with exhalant canal.
Described intake tunnel becomes 20-45 degree to be obliquely installed with horizontal plane.
Described intake tunnel becomes 30 degree and is obliquely installed with horizontal plane.
Described by-passing valve comprises plug, spring, spool; Plug is screwed onto on above-mentioned valve body, and spring is arranged between plug and spool, and spool cross section is arranged in above-mentioned valve inner for " ten " font; Plug inside has the groove coordinated with spool, and the outermost end of spool is in above-mentioned groove.
Described plug and spool all have a spring card slot in the place coordinated with spring, and two of spring is arranged in above-mentioned spring card slot.
Described by-passing valve is arranged on above-mentioned valve body on the user direction and arranges in the relative direction with heat exchanger.
Described exhalant canal becomes 20-60 degree to be obliquely installed with horizontal plane.
Described exhalant canal becomes 45 degree and is obliquely installed with horizontal plane.
The beneficial effects of the utility model are: owing to being communicated with intake tunnel between heating termination and by-passing valve, be communicated with exhalant canal between this by-passing valve and water outlet termination simultaneously, like this when the water of inside, heating termination is at expanded by heating, it flows out towards water outlet termination by by-passing valve, play the effect of pressure release like this, ensure safety; Intake tunnel is become 30 degree be obliquely installed with horizontal plane, flowing is comparatively efficient and convenient like this processes also more simultaneously; By-passing valve comprises the design of plug, spring, spool, and structure is simple, and can change at any time; The design of spring card slot makes spring not depart from original position in motion process, ensures that it can accurately regulate; By-passing valve is arranged on above-mentioned valve body towards on user direction, gives like this to use and install and keep in repair all more for convenience.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the built-in water by-pass valve body of forward type in embodiment;
Fig. 2 is the side view of the valve body in Fig. 1;
1. heating terminations, 2. water outlet termination, 3. by-passing valve, 31. plugs, 32. springs, 33. spools, 34. grooves, 35. spring card slots, 4. water inlet termination, 5. intake tunnel, 6. exhalant canal in figure.
Detailed description of the invention
Please refer to Fig. 1 and Fig. 2, the built-in water by-pass valve body of the forward type in figure, mainly comprise 2, one, the water outlet termination by-passing valve 3 that 1, one, a heating termination is communicated with heat exchanger; Certainly this valve body also comprises miscellaneous part, as water inlet termination 4 etc., because the innovative point of miscellaneous part and the present embodiment relates to not quite, therefore no longer too much describes above-mentioned conventional components.
In order to the water of inside, heating termination 1 can be imported in by-passing valve 3, an intake tunnel 5 can be processed between heating termination 1 and by-passing valve 3, when the water of by-passing valve 3 is stored into a certain amount of, it just can be flow in water outlet termination 2 by the exhalant canal 6 between by-passing valve 3 and water outlet termination 2.Above-mentioned intake tunnel 5 becomes 20-45 degree to be obliquely installed with horizontal plane, preferably 30 degree.Above-mentioned exhalant canal 6 becomes 20-60 degree to be obliquely installed with horizontal plane, preferably 45 degree.Adopt above-mentioned angle, facilitate the flowing of water first, second convenient processing.
