Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the gas stove quick-frying component comprises a body, wherein a main fire gas channel and a central fire gas channel are arranged in the body. The air inlet ends of the main fire gas channel and the central fire gas channel are respectively connected with a gas valve of the gas stove, and the tail ends of the main fire gas channel and the central fire gas channel are correspondingly connected with a main fire gas nozzle 4 and a central fire gas nozzle 9 of the gas stove burner. The aperture of the main fire throttle pipe 2 is smaller than that of a main fire gas passage, the main fire gas passage is divided into a first gas passage 1 connected with a gas valve of a gas stove in a high-pressure part and a second gas passage 3 connected with a main fire gas nozzle 4 of a gas stove burner in a low-pressure part, and the aperture of the main fire gas nozzle 4 is properly enlarged so as to adapt to the pressure reduction of the second gas passage 3 and keep the gas flow, namely the nominal load; the aperture of the main fire throttling pipe 2 is smaller than that of the main fire gas nozzle 4, so that throttling and depressurization effects can be improved, the pressure difference between the first gas channel 1 and the second gas channel 4 is increased, and the explosion is better realized; the same central flame restriction pipe 7 divides the central flame gas channel into a third gas channel 6 in the high-pressure part and a fourth gas channel 8 in the low-pressure part. The main fire throttle pipe 2 and the central fire throttle pipe 7 are arranged on the body or integrally processed with the body, and are preferably selected to be processed and then arranged in the body for convenient processing and ensuring the processing precision due to small aperture. According to conventional designs, the aperture of the gas nozzle is usually far smaller than the aperture of the air passage, and the aperture values of all gas passages and gas nozzles are determined according to design requirements. In the embodiment, the aperture of the main fire throttle pipe 2 is 1.36mm, the aperture of the main fire gas nozzle 4 is 1.72mm, and the gas pressure in the first gas channel 1 is throttled and reduced from about 1700pa to about 600pa in the second gas channel 3.
The first gas channel 1 and the second gas channel 3 are also communicated through a bypass, an electromagnetic valve 5 for controlling on-off is arranged between the first gas channel 1 and the second gas channel, the fourth gas channel 8 is respectively communicated with the first gas channel 1, the inlet of the bypass of the second gas channel 3 and the inlet of the fifth gas channel 10 are arranged on the same plane, and the electromagnetic valve 5 simultaneously controls on-off of the bypass of the first gas channel 1, the fifth gas channel 10 and the second gas channel 3. To reduce machining and facilitate die casting, the fifth gas passage 10 employs annular blind holes. To ensure adequate supply of gas, the cross-sectional area of the bypass of the first gas channel 1 is larger than the sum of the cross-sectional areas of the bypass of the second gas channel 3 and the fifth gas channel 10.
When the electromagnetic valve 5 is closed, the bypass is in an off state, and the fuel gas only passes through the main fire throttle pipe 2 and the central fire throttle pipe 7, and as shown in fig. 2, the fuel gas is in a normal combustion state, and the heat load is about 5kW. When the electromagnetic valve 5 is opened, the first gas channel 1, the second gas channel 3 and the fifth gas channel 10 of the bypass are communicated, gas passes through the bypass and the main fire throttle pipe 2 at the same time, the pressure of the gas in the second gas channel 3 is rapidly increased, the pressure of the gas is balanced with that of the first gas channel 1, and the pressure is increased to enable the main fire gas nozzle 4 to emit more gas, so that the heat load of the burner is increased; at the same time, the first gas passage 1 and the fifth gas passage 10 communicate, the gas pressure in the fourth gas passage 8 rises, and the central fire load increases, as shown in fig. 3. When the gas valve of the gas stove is in the maximum gear, the gas stove is in the quick-frying state, and the heat load is about 7kW. The electromagnetic valve 5 is closed, and the quick-frying state is changed into a normal combustion state.
The quick-frying firepower is generally mainly characterized in that the main firepower is greatly increased, the central fire gas channel can select the throttling and depressurization effects which are not throttled and depressurization or are slightly worse, and the whole quick-frying effect is relatively worse. The central fire gas channel does not throttle and reduces the pressure, and the fifth gas channel 10 can be canceled; the aperture of the central fire throttling pipe 7 is enlarged and larger than that of the central fire gas nozzle 9, so that the throttling and depressurization effects are reduced.
