Description
Technical field
Belong to modern fire technical field, be specifically related to one and repeat fast to open and close fire-fighting fountain head.
Background technology
Existing automatic control applicator, mainly comprises: the fire-fighting deluge system etc. that organic liquid temperature-sensitive shower nozzle, Lipowitz's alloy rapid response sprinkler, automatically controlled valve body control; Wherein organic liquid temperature-sensitive fire water spray nozzle, be most widely used, when this shower nozzle mainly relies on organic liquid to sense that ambient temperature raises, expansion of liquids breaks and connects the fire water supply suppression condition of a fire, and weak point is cracky, response is comparatively slow, can not suppress the early stage condition of a fire etc.; And Lipowitz's alloy rapid response sprinkler can realize quick induced environment temperature, but can not close voluntarily after fire is suppressed after opening; Although and the deluge system that automatically controlled valve body controls can solve the shortcoming of above-mentioned deficiency, do not have environment temperature automatic control function and need loaded down with trivial details electric control system, high cost in use, application has limitation.
Summary of the invention
The object of this invention is to provide one to repeat fast to open and close applicator, automatic water jetting fire-fighting when occurring for fire.Overcome existing automatic control applicator above shortcomings.
Shower nozzle of the present invention comprises tubular body, be enclosed within tubular body lower end and the end cap be slidably matched with it, the lower bottom distribution hole for water spraying of end cap, the upper open end that end cap is connected with tubular body has radial overhanging protuberance (flange or radial flange) to have screw hole on protuberance, the diameter of end cap inner chamber is greater than the diameter of upper end open, tubular body bottom is stretched into end cap inner chamber and is coordinated with end cap sealing suitable for reading is dynamic, ring cavity in being formed between end cap inner peripheral surface and tubular body outer peripheral face, the fixing aquaporin block head be slidably matched with tubular body endoporus on the bottom of end cap inner chamber, the water hole through tube wall is had near tubular body lower end, water hole divides at the relative tubular body of block head, be in when closing two positions and open and be closed two states, radial overhanging protuberance (ring flange or radial flange) is had in the middle part of tubular body, this protuberance there is the screw hole corresponding with the screw hole on end cap protuberance, tubular body top cover has the spring bearer plate moving with tubular body and coordinate, spring bearer plate there is the screw hole corresponding with the screw hole on end cap protuberance, there are two or more assembling screw rods to move and fit through end cap protuberance, protuberance in the middle part of tubular body and pressing plate, and stretching out the screw rod end fit on nut of pressing plate, end cap and tubular body are assembled into entirety, around warming memory alloy spring on tubular body outer surface between end cap protuberance and tubular body protuberance, on screw rod between tubular body protuberance and pressing plate, cover has the return spring pulling end cap to shrink to tubular body.It is more than basic technical scheme of the present invention.
The cooling-down effect of cold water to memorial alloy flowing through tubular body when opening for preventing shower nozzle is greater than the outer burning things which may cause a fire disaster of shower nozzle to the temperature rise effect of memorial alloy, shower nozzle is caused to be closed, in the tubular body of aquaporin axial hole the latter half embed low thermal conductivity every cool lining, the water hole overlapping of lining and tubular body lower end has water hole.
For reducing the more accurate displacement that return spring is retracted relative to tubular body with the impact produced between block head and end cap in tubular body lower end, there is screw thread in tubular body upper periphery face, and screw thread place is equipped with spring bearer plate extreme position and regulates pressure head.
The course of work of the present invention is: when work (without the condition of a fire), memorial alloy is not heated, and is in short length condition, return spring is upheld, and by end cap tension on tubular body, block head fills in tubular body axial bore, block the water hole on tubular body wall, current are in the state of being blocked.Occur when there being the condition of a fire, warming memory alloy spring is by hot stretched, and overcome return spring to the pulling force of end cap by the axially outer promotion of relative for end cap tubular body, block head is made to shift to the mouth of pipe from tubular body axial bore, water hole is exposed at tubular body inner chamber, be communicated with the water spray passage be made up of tubular body axial hole, the ring cavity between end cap and tubular body, the hole for water spraying on end cap bottom surface, sprinkling fire.After the condition of a fire disappears, environment temperature declines, and warming memory alloy spring bounces back, and return spring stretches, and is returned to by end cap and blocks current position, be again in preparation state.
Good effect of the present invention is: with tubular body and the end cap that is mated for basic building block, and by warming memory alloy spring and the cooperation of return spring under different temperatures environment, change the relative position between tubular body and end cap, control the switching in water route, the early stage condition of a fire can be suppressed fast, the temperature control realizing shower nozzle repeats to open and close automatically, is conducive to the safe and reliable operation ensureing fire-fighting system, and can reduces energy resource consumption.
