Description
Technical field
It the utility model is related to a kind of component of gas-heating water heater, more particularly to a kind of conversion valve.
Background technology
Gas-heating water heater is a kind of hot equipment for coming in rise, and hot water preparation and room are completed using natural gas or coal gas
Interior heating dual-use function.Gas-heating water heater of the prior art when in use, it is necessary to manual switching heating and hot water,
Each use is required for being manually operated, relatively complicated.
Utility model content
In order to solve the problems, such as present in background technology, the utility model provides a kind of for gas-heating water heater
Conversion valve, which can be automatically performed the switching for warm domestic hot-water, easy to use.
To reach above-mentioned purpose, the utility model adopts the following technical solution：
A kind of switching valve for gas-heating water heater, including heating water pipe, heating water pipe one end are heating water out,
Other end is communicated with water inlet pipe, and water inlet pipe is having hot-water line with heating water pipe joint branch, and the middle part for the water pipe that heats is set
There are upper inlet and lower outlet, upper inlet is connected with hot-water line, and spool is provided with upper inlet, and spool has head and bar portion, valve
The inner wall sealing of upper inlet, the bar portion of spool are extend into hot water outlet by core, head downside and the heating water pipe upper wall of spool
Between be provided with spring, discharge orifice is provided with the middle part of spool, saturating discharge orifice penetrates spool and directly communicated with hot water outlet.
Upper inlet and lower outlet and heating water pipe internal pipeline communicate.
Lower outlet is hot water outlet.
The head excircle of spool is provided with sealing ring.
The beneficial effects of the utility model are：By the switching valve, it can be achieved that supplying the automatic switchover of warm hot water, avoid
It is manually-operated cumbersome.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings
Fig. 1 is the structure diagram of conversion valve described in the utility model；
Embodiment
Explanation and embodiment are further described the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As shown in Figure 1, a kind of switching valve for gas-heating water heater, including heating water pipe 2,2 one end of heating water pipe
For the water out 11 that heats, other end is communicated with water inlet pipe 1, and water inlet pipe 1 is that there is hot-water line 3 in 2 joint branch of heating water pipe,
The middle part of heating water pipe 2 is provided with upper inlet 4 and lower outlet 9, upper inlet 4 and lower outlet 9 and heating 2 internal pipeline phase of water pipe
Logical, upper inlet 4 is connected with hot-water line 3, and lower outlet 4 is hot water outlet 10.Spool 5 is provided with upper inlet 4, spool 5 has head
Portion and bar portion, the head excircle of spool 5 are provided with sealing ring 6, and spool 5 is by the inner wall sealing of upper inlet 4, the bar portion of spool 5
It extend into hot water outlet 10, spring 8 is provided between heating 2 upper wall of water pipe on the downside of the head of spool 5.The middle part of spool 5
Discharge orifice 7 is provided with, saturating discharge orifice 7 penetrates spool 5 and directly communicated with hot water outlet 9.
Under normal circumstances, under the upward elastic force effect of spring 8, spool 5 rises, the hot water after burner heats
Enter from water inlet pipe 1 in heating water pipe 2 and entered from heating water out 11 in heating installation, until water in heating installation
After being full of, hot water is entered in upper inlet 4 by hot-water line 3, and under the action of water pressure, spool 5 declines, completely by heating water
Pipe 2 is closed, and at this time hot water is flowed down from the saturating discharge orifice 7 in spool 5, is flowed out from hot water outlet 10, is used for user.
By the switching valve, it can be achieved that supplying the automatic switchover of warm hot water, avoid manually-operated cumbersome.
It will be recognized by those skilled in the art, can be to above-mentioned on the premise of without departing from protection scope of the present invention
Embodiment carries out various modifications, change and combination, and thinks that this modification, change and combination are the models in originality thought
Within enclosing.
