Water inlet of hot water and cold water inlet are provided with hot water mixing valve, including water mixing valve body, water mixing valve body, it is characterised in that described
Check valve is provided with valve body between water inlet of hot water and cold water inlet, the check valve is by being located at institute on water mixing valve body
The mounting hole opened is arranged in valve body, and the check valve is arranged on the water channel between water inlet of hot water and cold water inlet.
As the further improvement of such scheme, the mounting hole outer enclosure has plug, is consolidated check valve by plug
It is scheduled in water mixing valve body on water channel.
Further, the hot-water cavity is separated with cold water cavity, different.
Further, the water mixing valve body side is provided with screen pack, and its effect is the impurity in filter water.Screen pack one end
Withstand on nonreturn valve core, play a part of fixed nonreturn valve core；The other end is fixedly connected with plug.
Further, the mounting hole is opened in valve body side, to prevent that water mixing valve body when mounted push up by water mixing valve body rear end
To wall.
A kind of central hot water circulation system using the above-mentioned central hot water mixed cold and hot water valve with check valve, including hot water
Device, hot-water line, stop valve, with water spot, cold water pipe, be joined together to form water route between each part, it is characterised in that institute
State and the water mixing valve with check valve is provided with water route.
Further, the water mixing valve with check valve is arranged on the distalmost end with water.
Compared with prior art, a kind of range hood that the utility model patent is provided has the advantages that：
1. screen pack is used, the susceptible to plugging problem of existing check valve is solved；
2. encapsulated using the plug of mounting hole, solve the problem of existing check valve installation, maintenance is inconvenient；
3. apparatus structure is simple, easy to operate.
