Description

Intelligent fluid safety shut-off device

The invention is a fluid safety interrupter, which is installed on the pipeline for conveying gas, and can block the flow of gas if the flow of gas is too large.

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

If the home is not equipped with natural gas pipelines, it is necessary to purchase additional gas barrels filled with liquefied gas. However, although the gas barrels are quite convenient to use, there have always been some problems. There will be a burst of gas with strong pressure at the moment of the valve, and this kind of gas with high pressure value 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 appliances.

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

In order to solve this problem, there are quite a variety of gas safety breakers on the market, which are installed on the pipeline for conveying gas. If the flow of gas is too large, it can block the flow of gas. If the road breaks, a strong air pressure will be generated in the pipeline instantly, so that the invention The light will be activated to block, and this feature can also prevent other conditions from causing excessive air pressure in the pipeline and damaging the gas equipment.

However, the known gas safety circuit breaker also has failures sometimes, for example, the rupture area of the pipeline is too small, so that the air pressure is not enough to trigger the blocking mechanism of the gas safety circuit breaker, so it must be manually operated. Forced to activate the blocking function of the gas safety circuit breaker. However, the common manual structure is a spiral structure. It takes a period of time from the start of operation to the activation of the blocking function. Generally speaking, the place where the gas barrel is placed is mostly narrow. Therefore, manual operation is also relatively troublesome, and it is actually a part that needs to be improved at present.

The present invention is provided with a solenoid valve. When the blocking function needs to be activated forcibly, the blocking function can be activated instantaneously only by starting the solenoid valve. faster and more convenient.

In order to achieve the above purpose and effect, the present invention provides an intelligent fluid safety blocking device, which includes: a main body with an air inlet, an air outlet, and a setting hole on the outside, and a first chamber inside the main body, A second chamber, the first chamber communicates with the air inlet, the second chamber communicates with the air outlet, the first chamber and the second chamber are connected by a through hole, the setting hole connected to the first chamber; a blocking member, which partially passes through the through hole; and an adjustment component, which is arranged in the setting hole, the adjustment component has a solenoid valve, and the solenoid valve includes a push rod, The pushing rod part is located in the first chamber and corresponds to the blocking member, and the adjusting assembly is operated to make the solenoid valve away from and close to the through hole.

For a more detailed understanding of the implementation of this creation, please watch it with the illustrations. As shown in the first to seventh figures, it is an intelligent fluid safety blocking device, which includes: a main body 1 with an air intake on the outside An opening 11, an air outlet 12, and a setting hole 13. The main body 1 has a first chamber 14 and a second chamber 15. The first chamber 14 communicates with the air inlet 11. The second chamber The chamber 15 communicates with the air outlet 12, the first chamber 14 and the second chamber 15 are connected by a through hole 16, the setting hole 13 is connected to the first chamber 14; a blocking member 2, its A part passes through the through hole 16; an adjustment component 3 is arranged in the setting hole 13, the adjustment component 3 has a solenoid valve 31, and the solenoid valve 31 includes a pushing rod 321, and the pushing rod 321 is partially positioned on the The first chamber 14 corresponds to the blocking member 2, and the adjustment assembly 3 is operated to make the solenoid valve 31 away from and close to the through hole 16. For specific implementation, please refer to the third and fourth figures. Due to gravity, the blocking member 2 is normally in a sinking state, and when the gas pressure value flowing into the first chamber 14 is sufficient When pushing against the gravity of the blocking member 2, the blocking member 2 will be closed on one side of the through hole 16 as shown in the fourth figure, and the gas flow has been blocked.

Alternatively, as shown in Figures 5 and 6, there is further an elastic positioning member 4, the two ends of which are respectively connected to the blocking member 2 and the pushing rod 321, and the elastic positioning member 4 has a stable moving track of the blocking member 2 The function of the blocking member 2 is flexible, and it will not disturb the movement of the blocking member 2 too much during the movement of the blocking member 2 .

The air inlet 11 of the present invention is used to connect the gas source (direct connection or pipeline), and the gas outlet 12 is used to connect (with pipeline) to the gas equipment. In this embodiment, the elastic positioning member 4 is taken as an example in the form of a spring, and the initial position of the blocking member 2 is as shown in the sixth figure. When the air pressure value of the gas entering through the air inlet 11 is too high, Then the blocking member 2 will be pushed to close one side of the through hole 16 .

In addition, the ruptured area of the pipeline is too small, so that the air pressure is not enough to block the component 2. At this time, the blocking function must be activated forcibly, but the present invention only needs to activate the solenoid valve 31 (such as: energizing, sending signals, etc., in this embodiment. The solenoid valve used in is the type that will push the push rod out when it is energized), and the push rod 321 will be displaced toward the through hole 16 as shown in the seventh figure, and then push against the blocking member 2 to close the through hole 16.
