Description

Technical Field

[0001] The invention relates to the technical field of gas pipes, and in particular to a gas distribution pipe with four sections. Background Art

[0002] The gas distribution pipe is an important component of the gas water heater. The gas enters the gas distribution pipe after being proportionally adjusted by the gas proportional valve. The gas flow is evenly distributed through the gas distribution cavity of the gas pipe. The solenoid valve on the gas distribution pipe is controlled to perform segmented combustion to achieve control of different loads.

[0003] Currently, mainstream gas water heaters are all automatic constant temperature water heaters. After the user sets the required temperature on the operation panel, the water heater will provide hot water according to the temperature set by the user. However, we found that when the water inlet temperature is high in summer, the hot water temperature will still be too high. If the user's water volume is too small, the water heater cannot reach the required temperature at all. The fundamental reason is that the existing mainstream gas distribution pipes have only 2 sections. Even if the number of nozzles is large after segmentation, the minimum heat load is still not small enough. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and to propose a gas distribution pipe with four sections.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: a gas distribution pipe with four sections, comprising: a distribution pipe body, the distribution pipe body is provided with an air inlet, a basic chamber, a first regulating chamber and a second regulating chamber, the air inlet is connected to the basic chamber, the basic chamber is respectively connected to the first regulating chamber and the second regulating chamber, and the connection between the basic chamber and the first regulating chamber and the second regulating chamber is provided with an installation position, the installation position is used to install a solenoid valve, and the basic chamber, the first regulating chamber and the second regulating chamber are all provided with nozzles.

[0006] As a preferred technical solution, the base chamber is provided with two nozzles, the first regulating chamber is provided with two nozzles, and the second regulating chamber is provided with one nozzle.

[0007] As a preferred technical solution, the base chamber is connected to the first regulating chamber through an air outlet pipe, and the central axis of the air outlet pipe and the central axis of the first regulating chamber have an angle of 30-50°.

[0008] As a preferred technical solution, the gas distribution pipe body is also provided with a pressure test channel, and the pressure test channel is connected to the basic chamber.

[0009] As a preferred technical solution, a blocking cover is respectively provided at both ends of the gas distribution pipe body, and the blocking cover and the gas distribution pipe body are in interference fit.

[0010] As a preferred technical solution, a sealing ring is further provided between the solenoid valve and the mounting position, and there is line contact between the sealing ring and the mounting position.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0012] The present invention provides a four-segment gas distribution pipe with a simple structure and a small minimum heat load power. It overcomes the defects in the prior art of the gas distribution pipe, such as a small number of segments, a large minimum heat load, and an inability to meet the user's demand for hot water, as well as the poor stability of the gas ejected from the nozzle caused by uneven gas distribution and unsatisfactory combustion conditions, and can meet the user's demand for hot water.

[0022] The present invention provides a gas distribution pipe with four sections, which can realize four sectioning modes. The first mode is to close the two solenoid valves 7. At this time, the connection between the basic chamber 3 and the first regulating chamber 4 and the second regulating chamber 5 is cut off, and the gas entering the basic chamber 3 can only be sprayed out from the nozzle 8 of the basic chamber 3; the second mode is to open the solenoid valve 7 between the basic chamber 3 and the first regulating chamber 4, and close the solenoid valve 7 between the basic chamber 3 and the second regulating chamber 5. At this time, the basic chamber 3 is connected to the first regulating chamber 4, and the connection between the basic chamber 3 and the second regulating chamber 5 is cut off. The gas can be sprayed out from the basic chamber 3 and the first regulating chamber 4. The third method is to close the solenoid valve 7 between the basic chamber 3 and the first regulating chamber 4, and open the solenoid valve 7 between the basic chamber 3 and the second regulating chamber 5. At this time, the basic chamber 3 is connected to the second regulating chamber 5, and the connection between the basic chamber 3 and the first regulating chamber 4 is cut off, and the gas can be sprayed from the nozzles 8 in the basic chamber 3 and the second regulating chamber 5; the fourth method is to open the two solenoid valves 7 at the same time.
