Description

Intelligent fluid safety shut-off device

technical field

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

Background technique

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., which are commonly used as fuel in daily life device of.

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 the gas damage to 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 gas stove is easily blocked by the cabinet of the system kitchen utensils), so it is convenient 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, the flow of gas can be blocked. A strong air pressure will be generated in the pipeline instantly, so that the application will act to block, and this feature can also avoid other situations that cause the air pressure in the pipeline to be too strong and damage the gas equipment.

However, the known gas safety breaker also has failures, for example, the area of the pipeline rupture is too small, so that the air pressure is not enough to trigger the blocking mechanism of the gas safety breaker, so the gas safety breaker must be activated manually.

The chamber 14 corresponds to the blocking member 2, and the adjustment assembly 3 is operated so that the solenoid valve 31 is away from and close to the through hole 16. For specific implementation, please refer to Fig. 3 and Fig. 4. Due to gravity, the blocking member 2 normally sinks state, and when the gas pressure value flowing into the first chamber 14 is sufficient to resist the gravity of the blocking member 2 and push it, the blocking member 2 will be closed on one side of the through hole 16 as shown in Figure 4, and the gas flow has been completed. block.

In addition, as shown in Figure 5 and Figure 6, there is further an elastic positioning member 4, the two ends of which are respectively linked with the blocking member 2 and the pushing rod 321, and the elastic positioning member 4 has the function of stabilizing the moving track of the blocking member 2 , and is inherently elastic, and will not interfere excessively with the movement of the blocking member 2 during the movement of the stable blocking member 2 .

According to the above content, the embodiment of the present application is further described in detail. The air inlet 11 of the present application 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 the example, the elastic positioning member 4 is in the form of a spring as an example, and the initial position of the blocking member 2 is as shown in Figure 6. When the air pressure value of the gas entering through the air inlet 11 is too high, it will push the blocking member 2. Part 2 closes one side of 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 blocking member 2. At this time, the blocking function must be forcibly activated, and the application only needs to activate the solenoid valve 31 (for example: energizing, sending signals, etc., in this embodiment The solenoid valve used is of the type that will push the push rod out when energized), and the push rod 321 will be displaced in the direction of the through hole 16 as shown in Figure 7, and then push against the blocking member 2 to close the through hole 16 On the one hand, it can be seen that this application is indeed faster and more convenient to use than the known products that can only be manually turned to forcibly activate the blocking function, and is indeed novel and progressive.

The advantage of using a non-automatic return type solenoid valve 31 is that it can prevent the blocking function from being damaged due to misoperation. Repeatedly ordering the action of the solenoid valve 31 causes the blocking function to be released. However, when the blocking function is activated in this application, it is only possible to go to the site where the application is placed and press the ventilation assembly 7 so that the push rod 321 is pushed back to return. The blocking function is released to increase the safety in use.

In addition, as shown in FIG. 9 of the present application, the initial position of the push rod 321 can be changed by operating the adjustment assembly 3 to change the air pressure value required to push the blocking member 2 to close the side of the through hole 16.

The anti-leakage washer 5 can prevent the gas in the main body 1 from passing between the push rod 321 and the through hole 34 of the housing 33. gap leaks.

As shown in Figure 6, there is further an anti-off piece 6 arranged in the groove 332, and the anti-off piece 6 stops on the side of the anti-leakage gasket 5 facing the blocking part 2, and the anti-off piece 6 can effectively prevent the The leakage washer 5 is displaced due to the expansion and contraction of the pushing rod 321 , so as to prevent the effect of the anti-leakage washer 5 from being reduced.

As shown in Figures 6 to 10, the adjusting member 35 includes a cover 351 and a bolt 352, the adjusting member 35 is set on the opening 335 with the cover 351, and a screw hole 3511 penetrates the cover 351 and communicates The accommodating space 334, the bolt 352 includes a connected head section 353 and a body section 355, the body section 355 is movably screwed in the screw hole 3511, the head section 353 is located in the accommodating space 334, and the head section 353 faces the One side of the electromagnetic valve 31 is recessed with a mounting groove 354, and the mounting groove 354 is provided with a magnetic element 356, which absorbs the electromagnetic valve 31. Generally speaking, the structure of the electromagnetic valve 31 must contain a magnetic material, so the magnetic element 356 can indeed absorb the solenoid valve 31. When the magnetic member 356 is displaced due to the rotation and expansion of the bolt 352, it can drive the displacement of the solenoid valve 31. This structure clearly defines the way that the adjusting member 35 can control the displacement of the solenoid valve 31.
