Electric control selection valve and active bottle control distribution method using the valve

Abstract

The invention discloses an electric control selection valve and an active bottle control and distribution method using the same. The electric control selection valve is combined by connecting an electric control driving device and a selection valve, wherein the inside of the electric control driving device is provided with a metal sealing film which divides the interior of the electric control driving device into an upper space and a lower space, and the electric control driving device is also provided with a driving gas outlet; and the body of the selection valve is provided with a main air inlet and a main air outlet. The method comprises that a plurality of fire-extinguishing and storing bottles and the electric control selection valves are arranged, and the main air outlet of each electric control selection valve is respectively opposite to a protection area; and one of the fire-extinguishing and storing bottles is used as an active bottle, and the other fire-extinguishing and storing bottles are used as passive bottles. The electric control selection valve has the advantages of reliably and steadily opening a valve port, and combining the electric control driving device and the selection valve into a whole. The method has the advantages of reducing control links, improving the control reliability, using one fire-extinguishing bottle as the active bottle, turning on the selection valve and the passive bottles thereof according to needs, and directly starting by electric control.

Description

technical field [0001] The invention relates to a selection valve for gas fire extinguishing and a control distribution system, in particular to an electric control selection valve and an active bottle control distribution method using the valve. Background technique [0002] In the combined distribution of the current gas fire extinguishing system, the start-up structure of the key component selection valve is as follows: figure 1 As shown, it is provided with a tripping mechanism consisting of a tripping shaft 12', a starting handle 11' and a cross bar arm 13', and an air inlet 15' and an air outlet 16' are provided on the starting cylinder 14'. The schematic diagram of the control distribution of the selector valve used in the fire extinguishing system is as follows: figure 2 As shown, each selector valve 1' needs to be configured one-to-one with the starting small steel cylinder 9', the air inlet 15' on the starting cylinder 14' is connected with the starting small ste...

Problems solved by technology

like figure 2 The mechanical emergency operation in the starting mode shown is to manually open the selection valve of the required fire extinguishing protection zone and set the fire extinguishing agent storage bottle set to be sprayed to the protection zone in the case of the failure of the first two kinds of start-ups. The fire extinguishing agent storage bottle group in which protected area is distinguished by marks, some are sprayed to one protected area, some are sprayed to two protected areas, and some are sprayed to multiple protected areas (up to 8 protected areas) , during mechanical emergency operation, need to find out one by one, and manually start one by one, this just might delay fighter plane or produce operating error, especially the fire extinguishing agent storage bottle quantity that large-scale protection area is used is many (dozens to several hundreds) ), it is more difficult to achieve accurate installation

The method of mechanical linkage (cable mechanism) is usually adopted, the mechanism is complicated and the installation is very difficult

like image 3 As shown in the control method that one active bottle corresponds to one protection area, when the control of the active bottle fails and mechanical emergency operation is required, there is also a search for the selection valve of the protection area and the fire extinguishing agent storage bottle group to which it belongs, and use them one by one. Manual opening may delay fighters or cause operational errors
