Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model technology.It should be appreciated that specific embodiment described herein is only used to
It explains the utility model, is not used to limit the utility model.
As illustrated in fig. 1 and 2, a kind of datonation-inhibition fire extinguishing high speed pay-out valve, including valve body 1 and gas generator 2, in the valve body
Extinguishing chemical import 3 and extinguishing chemical outlet 4,4 coaxial arrangement of the extinguishing chemical import 3 and extinguishing chemical outlet, to improve are provided on 1
Extinguishing chemical spurts speed and smoothness in valve body, is provided in the runner of the valve body 1 plunger shaft 5 and goes out for connecting
Fiery agent import 3 and the extinguishing chemical access 6 of extinguishing chemical outlet 4, in the valve body 1,5 bottom of plunger shaft be provided with cover board 12, institute
