Abstract
The utility model relates to an automatic return nozzle which comprises a nozzle body, wherein a collar nut is arranged at the top of the nozzle body, a back cap is sleeved in the middle of the nozzle body, and a nozzle hole is formed at the lower part of the nozzle body. The automatic return nozzle further comprises a piston, a spring, a nut and a spray cover, wherein the piston is arranged inside the nozzle body, a screw is arranged at the bottom of the piston, the spring is arranged in the nozzle body, one end of the spring is fixed at the bottom end inside the nozzle body, the other end of the spring is fixed at the bottom of the piston, the screw penetrates the spring to extend out of the bottom of the nozzle body, the nut is in threaded connection with the part of the screw exposed out of the bottom of the nozzle body, and the spray cover is sleeved outside the lower part of the nozzle body and fixed through the nut in a clamping manner. Compared with the prior art, the automatic return nozzle can prevent the nozzle hole from being blocked when being used in a dirty or dusty area, so that the extinguishing agent can be used for timely and reliable extinguishment according to the arrangement and flow at design time.
Description
Technical field
The utility model relates to the nozzle of fire fighting gas fire extinguishing system, is the automatic reposition-type nozzle specifically.
Background technology
In traditional fire fighting gas fire extinguishing system, some nozzle be arranged in dust or dust many places, the time has been grown the obstruction that can cause nozzle bore, causes time-delay that extinguishing medium spurts or inhomogeneous, makes the effect of fire extinguishing or promptness can not get ensureing.Based in such cases, we study and have developed can automatically reset nozzle.
Summary of the invention
The purpose of this utility model is to have grown the obstruction that can cause nozzle bore in order to solve in prior art the time, cause time-delay that extinguishing medium spurts or inhomogeneous, make the effect of fire extinguishing or the defective that promptness can not get ensureing, provide a kind of automatic reposition-type nozzle to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
the automatic reposition-type nozzle, comprise nozzle body, this nozzle body top is provided with collar nut, described nozzle body middle part is arranged with back of the body cap, described nozzle body bottom is provided with nozzle bore, it is characterized in that, also comprise piston, spring, nut, the spray cover, described piston is located at nozzle body inside, described piston base is provided with screw, described spring is located in nozzle body, one end is fixed on the nozzle body inner bottom, the other end is fixed on piston base, described screw passes spring, stretch out bottom nozzle body, the part of described nut setting bottom screw exposes nozzle body is threaded, the described spray enclosure is located at the outside of nozzle body bottom, connect and fix by nut.
Described nut is the acorn nut of an end sealing.
Described piston is located at nozzle body inside, when resetting, is in respectively below and the top of nozzle bore at spring-compressed.
Beneficial effect
Automatic reposition-type nozzle of the present utility model compared with prior art, can prevent that nozzle bore is blocked when being used for having the place such as dust or dust, thereby makes layout and the flow of extinguishing chemical can be according to design the time come in time fire extinguishing reliably.
