Detailed ways

In the following, only certain exemplary embodiments are briefly described. The described embodiments may be modified in various different ways, without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as

As shown in FIG. 1 and FIG. 2, the embodiment of the present application provides a gas separation device 100 including a plurality of air separation tubes 1 and at least one gas delivery tube 3. Among them, each of the air outlet pipes 1 is parallel to each other and spaced apart. Each of the air separation pipes 1 is provided with a plurality of air nozzles 2. The gas nozzle 2 is for supplying gas to the ejector tube of the corresponding flame arrester (not shown). The gas pipe 3 is in communication with each gas pipe 1. The gas pipe 3 connects the respective gas pipes 1 into a one-piece structure. The gas pipe 3 is for supplying gas to each of the gas separation pipes 1. The gas delivery pipe 3 is provided with a gas transmission port 4 for connecting a valve.

Among them, the number of the air separation pipe 1 mainly depends on the number of the ejector pipes provided on the fire extinguisher, and the number of the air distribution pipes 1 to be arranged is adjusted according to the number of the ejector pipes disposed on the firearm.

In an embodiment, in order to better realize the fixing of the three air separation pipes 1, the integrated structure formed by the gas pipe 3 and the air separation pipe 1 is more stable, and the air separation pipes 1 can be located at the same end of the gas pipe 3 at the same end. The connecting member 5 is integrally connected, and the connecting member 5, the air dividing pipe 1 and the air pipe 3 are combined to form a mesh structure. In order to facilitate the fixing of the air separation device 100 to other required equipment, a mounting platform 51 can be provided on the connecting member 5.

In a specific example, as shown in FIG. 1, the air separation ducts 1 are three, and the three air separation ducts 1 are disposed in parallel and parallel to each other. The gas pipe 3 is disposed perpendicular to the middle of the three gas pipe 1, and the gas pipe 3 penetrates the middle of each gas pipe 1 and is in communication with each gas pipe 1. The ends of the respective manifolds 1 on the side of the gas pipe 3 are integrally connected by a connecting member 5, and the ends of the respective manifolds 1 on the other side of the gas pipe 3 are integrally connected by another connecting member 5. The three air separation pipes 1 together with one gas pipe 3 and two connecting members 5 constitute a "field" shaped grid structure. Since the gas pipe 3 is located in the same plane as the gas pipe 1 and the connecting member 5, the space occupied by the gas separation device 100 is effectively saved. At the same time, since the gas pipe 3 is integrally connected to the middle of the three gas pipe 1, it is possible to simultaneously supply the same amount of gas to each of the gas pipes 1.

In order to smoothly convey the gas in the gas pipe 3 to each of the gas pipes 1, it is preferable that the gas pipe 3 is disposed perpendicular to each of the gas pipes 1.

In one embodiment, the communication between the gas delivery pipe 3 and the gas distribution pipe 1 can be understood as a direct communication between the two, and can also be understood as the gas flow communication between the two.

In a specific embodiment, when the gas pipe 3 and the gas pipe 1 are in direct spatial communication with each other, as shown in FIG. 2-4, the gas pipe 3 can sequentially penetrate the middle of each gas pipe 1 so that each The inside of the air separation pipe 1 communicates with the inside of the gas pipe 3 to form a gas passage. Alternatively, each of the air pipes 1 penetrates the gas pipe 3 such that the inside of each of the gas pipes 1 communicates with the inside of the gas pipe 3 to form a gas passage.

In a variable embodiment, when the gas pipe 3 and the gas pipe 1 are in airflow communication, the gas pipe 3 may be disposed on one side of the plane of each gas pipe 1 (for example, the upper side or the lower side of the plane), And communicating with the middle of each of the air separation pipes 1. That is, the pipe wall of the gas pipe 3 is in direct communication with the joint of the central pipe wall of each of the gas pipe 1, so that the gas in the gas pipe 3 can flow into the respective gas pipe 1 through the communication position.

It should be noted that, in the above embodiments, the connection position of the gas pipe 3 and the gas pipe 1 can be adaptively adjusted according to the work requirement, and the gas pipe 3 is not limited to be in communication with the middle portion of the gas pipe 1, and the gas pipe 3 can also be It is connected to any position on each air pipe 1 . When the gas pipe 3 is connected to the non-middle position of the gas pipe 1, the specific arrangement (including but not limited to the connection and arrangement) may be the same as that of the gas pipe 3 described in the above embodiments, so Further, the implementation can be carried out with reference to the above embodiments.

Preferably, the blocking member 6 adopts a sealing cover or a sealing plug structure interposed at the port of the air separation pipe 1.

In one embodiment, the air separation pipe 1 and the gas delivery pipe 3 are integrally formed by a die casting process to form a unitary structure. This can increase the strength of the overall structure of the gas separation device 100 while the manufacturing process is simple. The integrally formed gas separation device 100 is more airtight, does not cause gas leakage, and improves safety.

In one embodiment, as shown in FIG. 5, the air outlet pipe 1 is provided with a pressure detecting port 11. The pressure detecting port 11 is used to connect the pressure detecting device. The pressure detecting means can be used not only for detecting the pressure of the gas flowing into the gas dividing pipe 1, but also for detecting the pressure before the gas in the gas dividing pipe 1 is ejected through the gas nozzle 2. Since the pressure loss occurs in the gas entering the gas separation device 100 (for example, the pressure loss generated by the gas supply pipe 3 to the gas supply pipe 1), the gas pressure before entering the gas nozzle 2 in the gas separation pipe 1 is detected. The regulation of the pressure and flow rate of the gas ejected from the nozzle 2 can be achieved. For example, the size of the orifice of the gas nozzle 2 is regulated or the magnitude of the gas pressure in the manifold 1 is regulated.

The pressure detecting port 11 can be disposed at any position of the air separation pipe 1, and can be selected according to needs and manufacturing processes. For example, it is provided at both ends, the middle portion of the air separation pipe 1, or a position close to any air nozzle 2. The number of the pressure detecting ports 11 can also be adaptively adjusted according to the work needs or the structure of the gas separation device 100. For example, when the internal spaces of the respective air separation pipes 1 are in communication with each other, the pressure detecting port 11 can be provided only on one of the air separation pipes 1. When the internal spaces of the respective air separation ducts 1 are not connected and are independent pipelines, the pressure detecting ports 11 may be provided on the respective air separation ducts 1 to monitor the gas pressure loss in each of the air separation ducts 1.

In one embodiment, a pressure detecting device is detachably provided on the pressure detecting port 11. A cover 12 is detachably provided on the pressure detecting port 11 for sealing the pressure detecting port 11. When the pressure detection is not required, the cover 12 is placed on the pressure detecting port 11. When it is necessary to detect the pressure in the air separation pipe 1, the cover 12 is removed and the pressure detecting device is installed, thereby detecting the flow into the air pipe 1 Gas pressure loss in.

The closure 12 can employ any of the prior art seals. For example, the closure 12 can employ a sealing plug, a sealing cover. The pressure detecting port 11 can also be blocked by bolts and gaskets. The manner of sealing the pressure detecting port 11 can be selected as needed, and is not limited to the one described in the embodiment, as long as it can be completely sealed when the pressure detecting device is detached from the pressure detecting port 11.

In order to increase the strength and airtightness of the pressure detecting port 11 provided on the air separation pipe 1, the pressure detecting port 11 may be integrally molded and die-cast on the air pipe 1.
