The valve assembly of gas range
Technical field
The utility model relates to a kind of gas range, specifically is the valve assembly of gas range.
Background technique
Gas range producer is usually all in the performance of propaganda firepower size, burner, and the less relevance Consumer is in use to the adjusting function of firepower.We will make various delicious foods when culinary art, all will utilize various cooking methods, and every kind of cooking method all needs different firepower sections to accomplish, and is not only big fire.The firepower regulation range of existing common on the market gas valve is little, does not have outer ring fire, interior ring fire to become synchronously greatly and the function of the adjusting that diminishes.Therefore, be necessary to do further improvement.
The model utility content
The purpose of the utility model aims to provide a kind of ability and realizes that outer ring fire and interior ring fire become adjusting big and that diminish synchronously, secondly also have the valve assembly of the gas range of wide cut regulatory function, to overcome deficiency of the prior art.
Press the valve assembly of a kind of gas range of this purpose design; Comprise that the spool, the spool that are provided with in valve body and the valve body are connected with valve rod; Spool is connected with inside and outside tracheae; Its structure characteristic is that spool is provided with upper and lower ducts for effluent air, and upper and lower ducts for effluent air is for to be made up of the hole more than two and an above groove of distributing in 0 ° to the 270 ° angular range that is arranged on the spool circular surfaces respectively.
Said upper and lower ducts for effluent air comprises along spool face clockwise direction or counterclockwise main pore, inferior pore and the groove of setting arranged evenly successively; Main pore internal diameter is greater than inferior pore internal diameter.
Be provided with the adjusting positioning device between said valve body and the valve rod, regulate positioning device and be provided with the limiting stopper that the restriction valve rod rotates in 90 ° to 270 ° scope.
The beneficial effect of the utility model is: utilize upper and lower ducts for effluent air, realize the synchronization regulation of inner and outer rings firepower; Upper and lower ducts for effluent air adopts hole and groove to be used, and realizes stepless firepower adjustment.The utility model can satisfy Consumer's needs, and various firepower required when realizing culinary art are regulated.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 5; A kind of valve assembly of gas range; Comprise that the spool, the spool that are provided with in valve body and the valve body are connected with valve rod; Spool is connected with inside and outside tracheae, and spool is provided with upper and lower ducts for effluent air, and upper and lower ducts for effluent air is for to be made up of the hole more than two and an above groove of distributing in 0 ° to the 270 ° angular range that is arranged on the spool circular surfaces respectively.Last ducts for effluent air 2.1 comprises along main pore 2.3, inferior pore 2.1 and the groove 2.5 of spool 2 surperficial clockwise directions setting arranged evenly successively; Following ducts for effluent air 2.2 comprises along spool 2 surface counterclockwise successively the main pore of the following row of setting arranged evenly 2.6, row's time pore 2.7 and following emissions groove 2.8 down.Be provided with between valve body 1 and the valve rod 3 and regulate positioning device 1.1, regulate positioning device 1.1 and be provided with the limiting stopper 1.2 that restriction valve rod 3 rotates in 90 ° to 270 ° scope.
Referring to Fig. 6, traditional gas control valve can only be implemented the outer shroud firepower and regulate, and combustion gas tolerance changes little, cannot satisfy the required firepower section of the cooking.Referring to Fig. 7, adopt this structure after, implement inner and outer rings firepower synchronization regulation, combustion gas tolerance changes greatly, realizes every kind of required different firepower section of cooking method.
