Embodiment 1

[0033] During the use of gas equipment, the connection between the gas valve and the indoor gas pipeline is not in place, and gas leakage will occur; the aging of the internal connection seal of the whole machine will also cause gas leakage. In the prior art, a gas detection device installed outside the gas equipment is usually used for detection. When the gas equipment is placed in a large space, the leakage of gas cannot be detected in time, which may easily lead to safety accidents. In order to solve the above problems, this embodiment provides a gas leakage detection method for gas equipment. The gas pipeline assembly is provided in the gas equipment, and the gas pipeline assembly is connected to the gas main pipe outside the gas equipment. The gas supply pipeline for the gas supply of multiple gas equipment.

[0034] The gas equipment also includes a gas leakage detection device, which includes a first detection device for detecting the pressure or flow in the gas main pi...

Embodiment 2

[0041] This embodiment provides a gas leakage detection method for gas equipment, which is an improvement made on the basis of Embodiment 1. This embodiment uses the detection of gas pressure by the first detection device and the second detection device as an example for illustration. At this time, both the first detection device and the second detection device include pressure sensors.

[0042] The gas pipeline assembly includes a gas valve and a gas pipeline. One end of the gas pipeline is connected to the gas valve through a quick joint, and the other end of the gas pipeline is connected to the gas main pipe. In this embodiment, the first detection device is arranged between the gas main pipe and the gas pipeline or It is arranged in the main gas pipe, and the second detection device is arranged between the quick joint and the gas valve. Such as figure 2 As shown, the gas leakage detection method includes the following steps:

[0043] S21, the gas equipment is powered on...

Embodiment 3

[0051] This embodiment provides a gas leakage detection method for gas equipment, which is an improvement made on the basis of Embodiment 1. This embodiment uses the detection of gas flow by the first detection device and the second detection device as an example for illustration. At this time, both the first detection device and the second detection device include flow sensors. Such as image 3 As shown, the gas leakage detection method includes the following steps:

[0052] S31, the clothes drying equipment is powered on.

[0053] S32. Obtain the flow value FA detected by the first detection device at time T0 0 , and the flow value FB detected by the second detection device 0 , and calculate the difference △F of the detected flow values 0 =FA 0 -FB 0 .

[0054] S33. Obtain the flow value FA detected by the first detection device at time T1 1 , and the flow value FB detected by the second detection device 1 , and calculate the difference △F of the detected flow value...

Abstract

The invention relates to the technical field of gas devices, and discloses a gas device and a gas leakage detection method thereof. A gas pipeline component is arranged in the gas device and connectedto a gas manifold outside the gas device. The gas device further comprises a gas leakage detector, which comprises a first detector for detecting pressure or flow inside the gas manifold and a seconddetector for detecting pressure or flow inside the gas pipeline component. The gas leakage detection method comprises the following steps: acquiring detected values of the first detector and the second detector at the same time and calculating a detection difference; and determining whether gas leaks or not based on a difference between the detection differences at two continuous time. Since thegas leakage detection method of the gas device determines whether gas leaks or not based on the difference between the detection differences at two continuous time, gas leakage can be detected promptly by the method. The gas device can promptly detect whether the gas device leaks to avoid safety accidents.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to a gas leakage detection method of gas equipment and the gas equipment. Background technique [0002] In today's society, the use of gas equipment is very common, which brings great convenience to people's daily life. However, during the use of gas equipment, such as a gas clothes dryer, the connection between the gas valve and the indoor gas pipeline is not in place, and gas leakage is prone to occur; the aging of the internal connection seal of the whole machine is prone to gas leakage. [0003] To solve the above problems, we basically rely on the combustible gas detection device in the dryer room to detect, but the room where the gas dryer is usually placed is: garage, laundry room, etc., the space is large, and it takes a long time to detect after a leak occurs Until the gas leaks, the gas dryer is still in working condition during this period, and it may explode if it...
