Description

Intelligent Fluid Safety Interrupting Device

technical field

The utility model relates to a fluid safety interrupter, which is installed on the pipeline for conveying gas, and can interrupt the flow of the gas if the gas flow is too large.

Background technique

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. device of.

If the home is not equipped with a natural gas pipeline, an additional gas tank filled with liquefied petroleum gas must be purchased. However, although the gas tank is quite convenient to use, there have always been some problems. At the moment of the gas valve, there will be a burst of gas with strong pressure, and 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 gas equipment.

In addition, there is another 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 kitchen stove is easily blocked by the cabinet of the system kitchen utensils). It will lead to a large amount of gas leakage and cause waste and even danger.

In order to solve this problem, there are quite a variety of gas safety circuit breakers on the market, which are installed on the pipelines that transport gas. If the gas flow is too large, the flow of gas can be blocked. A strong air pressure will be instantly generated in the pipeline, so the utility model will act to cut off, and this feature can also avoid the situation that the air pressure in the pipeline is too strong and the gas equipment is damaged due to other conditions.

However, the existing gas safety circuit breaker may also fail. For example, the rupture area of the pipeline is too small, so that the flow rate is not enough to trigger the blocking mechanism of the gas safety circuit breaker. Therefore, the gas safety circuit must be manually operated to force the start of the gas safety circuit breaker. The interruption function of the circuit breaker, however, the common manual structure is a spiral structure. It takes a period of time from the start of the operation to the start of the interruption function. Generally speaking, the place where the gas barrel is placed is mostly narrow, so manual operation is also more troublesome. It is the part that needs to be improved.
