Abstract

This creation is a gas safety circuit breaker, which includes: a main body, a blocking member and an elastic return member. This creation is installed on the pipeline for transporting gas. If the gas flow is too large, the flow of gas can be blocked. Knowing that if the pipeline for transporting gas breaks, a strong air pressure will be instantly generated in the pipeline, so this creation will act to block the gas and stop the gas from continuing to leak. Avoid other conditions that cause the pressure in the pipeline to be too strong and damage the gas equipment.

Description

gas safety circuit breaker

This creation is a gas safety circuit breaker, which is installed on the pipeline for conveying gas. If the gas flow is too large, it can block the flow of gas.

Gas refers to the gas that can be used as fuel (such as gas, coal gas), which can generate a lot of heat after combustion, so it is widely used in life, such as water heaters, gas stoves, etc. equipment for fuel.

If the home is not equipped with a natural gas pipeline, it must be purchased additionally. Due to its flammable characteristics, gas needs to be stored rigorously. It is a more common practice to store it in metal barrels. The gas barrel is equipped with liquefied gas. However, although the gas barrel is quite convenient to use, there are still some problems. This kind of gas with high gas pressure is very likely to cause damage to the back-end pipeline (the pipeline between the gas equipment and the gas barrel), or damage to the gas equipment.

There is also a common problem, that is, it is difficult to find the rupture of the back-end pipeline if it is closer to the gas equipment (for example, the part of the back-end pipeline close to the gas stove in the kitchen is easily blocked by the cabinet of the system kitchen utensils). It will lead to a large amount of gas leakage and waste, and even dangerous.

This creation is a creation installed on the pipeline for conveying gas. If the gas flow is too large, the flow of gas can be blocked. It should be known that if the pipeline for conveying gas breaks, the pipeline will instantly generate There is a strong air pressure, so this creation will act to block the gas to stop the continuous leakage of gas. The same feature can also prevent other conditions from causing excessive pressure in the pipeline and damage to the gas equipment. .

In order to achieve the above purpose and effect, the present invention provides a gas safety circuit breaker, which includes: a main body with an air inlet and an air outlet on the outside of the main body, and a first chamber and a second chamber inside the main body. The first chamber is communicated with the air inlet, the second chamber is communicated with the air outlet, and the first chamber and the second chamber are connected by a through hole; a blocking member is located in the The main body has a connected body section and a head section, the body section passes through the through hole, the head section cannot pass through the through hole and is located in the first chamber; and an elastic return piece, a part of which is located in the first chamber indoors and connected to the head section of the blocking element.

Return to the original shape, and the head section 22 is driven away from the through hole 15 during the process of returning to the original shape.

From the above content, we can know the conditions for displacing the blocking member 2, that is to say, when the air pressure flowing through the creation, if the generated thrust is greater than the return force of the elastic return member 3, the head will appear as shown in the fourth figure. The segment 22 is pushed, which in turn causes the through hole 15 to be closed, and the air inlet 11 and the air outlet 12 are in a disconnected state, completely blocking the outflow of gas from the air outlet 12. This structure achieves that when the gas flow is too large, the The function of blocking the flow of gas. Generally speaking, if the pipeline for transporting gas is ruptured, a strong air pressure will be instantly generated in the pipeline. As a result, this creation will act to block and stop The gas continues to leak, and this feature can also prevent other conditions from causing excessive pressure in the pipeline to damage the gas equipment. It can be seen that this work is creative and novel.
