Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of this patent, it is noted that unless otherwise specifically stated or limited, the terms "mounted," "connected," and "disposed" are intended to be construed broadly, e.g., as meaning fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in this patent may be understood by those of ordinary skill in the art as appropriate.
As shown in fig. 1, a combustible gas detector 1 is fixed to a spray water cannon 3 by a fixing rod 2. The upper end of the pneumatic ball valve body 4 is connected with the spray water cannon 3 through a flange 11, and the lower end of the pneumatic ball valve body is connected with the high-pressure water inlet pipe 5 through a flange 11. Solenoid valve 6 is connected with instrument wind pipeline 7, and combustible gas detector 1 detects the workplace combustible gas concentration in real time to accessible instrument wind control solenoid valve 6, 6 steerable actuating mechanism 8 of solenoid valve open pneumatic ball valve body 4, trigger spraying water cannon 3 and continuously provide high-pressure water smoke. The pneumatic ball valve also comprises a hand wheel 9, and the hand wheel 9 is connected with the actuating mechanism through a valve rod 10.
In this embodiment, the pneumatic ball valve is an "on-off type full-bore steel ball valve" having the same bore as the high-pressure water inlet pipe 5. An AC24V power supply module is arranged in the combustible gas detector 1, and the fixed rod 2 and the valve rod 10 are DN5020# steel tubes. The solenoid valve 6 is a single-electric-control two-position four-way normally closed solenoid valve made of 304/316 stainless steel, and the solenoid valve 6 is electrically connected with the combustible gas detector 1.
The spraying water cannon 3 is for being fixed in the formula water cannon of letting out certainly on ground, works as the utility model discloses be applied to the district that freezes, will let out the mouth and set up below freezing line to prevent freezing in the spraying water cannon.
The working principle is as follows: the utility model relates to a device for restraining combustible gas from being exploded is installed in the place where combustible gas is likely to leak or is easy to gather after leaking. When the combustible gas detector detects that the concentration of the combustible gas in the air reaches 50% of the lower explosion limit (LFL) of the combustible gas, the electromagnetic valve 6 controls the actuating mechanism 8 to automatically open the valve body 4 under the action of instrument wind, and at the moment, the spray water cannon 3 is opened and sprays a mist water ball with the diameter of about 30 meters to the space where the water cannon is located. On one hand, the atomized water can disperse the combustible gas cloud cluster, so that the concentration of the combustible gas in the air is lower than the lower explosion limit (LFL) of the combustible gas by less than 50 percent, thereby preventing the combustion and explosion; on the other hand, the temperature of the air can be controlled to be lower than 25 ℃ by continuously spraying the atomized water, and the ignition temperature of the combustible gas is required to be higher than 100 ℃, so that the ignition of the combustible gas can be prevented by continuously spraying the atomized water. To sum up, the utility model discloses can suppress the combustible gas who leaks or the gathering and be lighted through lasting vaporific water to avoid combustible gas to leak the incident and upgrade to conflagration or explosion accident.
