Description

A kind of quick repetition opens and closes applicator

Technical field

Belong to modern fire technical field, and in particular to a kind of quick repetition opens and closes fire-fighting fountain head.

Technical background

Existing automatic control applicator, mainly includes：Organic liquid temperature-sensitive shower nozzle, the spray of Lipowitz's alloy quick response Head, fire-fighting deluge system of automatically controlled valve body control etc.；Wherein organic liquid temperature-sensitive fire water spray nozzle, is most widely used, this When kind of shower nozzle mainly senses ambient temperature rise by organic liquid, liquid swelling fracture is connected fire water supply and suppressed The condition of a fire, weak point is cracky, response is relatively slow, can not suppress early stage condition of a fire etc.；And Lipowitz's alloy rapid response sprinkler Quick induced environment temperature can be realized, but can not voluntarily be closed after fire is suppressed after opening；And automatically controlled valve body control Deluge system although can solve the problem that above-mentioned not enough shortcoming, but without environment temperature automatic control function and need cumbersome Electric control system, too high using upper cost, using there is limitation.

The content of the invention

Applicator is opened and closed it is an object of the invention to provide a kind of quick repetition, automatic water jetting disappears when occurring for fire It is anti-.Overcome existing automatic control applicator above shortcomings.

The end cap that the shower nozzle of the present invention includes tubular body, is enclosed on tubular body lower end and is slidably matched with it, end cap Lower bottom is distributed hole for water spraying, and the upper open end that end cap is connected with tubular body has radially overhanging protuberance, and (flange is radial Flange), there is screw hole on protuberance, the diameter of end cap inner chamber is more than the diameter of upper open end, tubular body bottom inserting end Cooperation is simultaneously moved in cap inner chamber with end cap upper open end sealing, holds ring cavity in being formed between cap inner peripheral surface and tubular body outer peripheral face, The fixed aquaporin block head being slidably matched with tubular body endoporus, has close to tubular body lower end on the bottom of end cap inner chamber Through the water hole of tube wall, water hole is in when block head is divided to respect to tubular body, closes two positions and opens and be closed two Having in the middle part of the state of kind, tubular body on radially overhanging protuberance (ring flange or radial flange), the protuberance has and end cap The corresponding screw hole of screw hole on protuberance, tubular body top is cased with and the dynamic spring bearer plate coordinated of tubular body, bullet There is the screw hole corresponding with the screw hole on the cap protuberance of end on spring pressing plate, having two or more to assemble, screw rod is dynamic to fit through end Protuberance and pressing plate in the middle part of cap protuberance, tubular body, and upper cap nut is assembled in the screw rod end for stretching out pressing plate, by end cap and Tubular body assembling is integral, and warming is surrounded on the tubular body outer surface between end cap protuberance and tubular body protuberance Pulling end cap is cased with memory alloy spring, the screw rod between tubular body protuberance and pressing plate to returning that tubular body shrinks Position spring.It is above the basic technical scheme of the present invention.

The cold water that tubular body is flowed through during to prevent that shower nozzle from opening is more than burning things which may cause a fire disaster outside shower nozzle to the cooling-down effect of memorial alloy To the temperature rise effect of memorial alloy, shower nozzle is caused to be closed, the insertion of axial hole the latter half is low in the tubular body of aquaporin leads Hot coefficient every cool bushing, bushing and the water hole overlapping of tubular body lower end have water hole.

For the impact that is produced between tubular body lower end and block head of reduction return spring and the relative tubulose master of end cap The more accurate displacement that body is retracted, has on tubular body upper periphery face and spring bearer plate limit position is equipped with screw thread, screw thread Put regulation pressure head.

The present invention the course of work be：When work (no condition of a fire), memorial alloy is not heated, is in short length state, returns Position spring is upheld, and end cap is tensed on tubular body, block head fills in tubular body axial bore, blocks tubular body wall On water hole, current are in the state of being blocked.When there is the condition of a fire, warming memory alloy spring is overcome back by hot stretched The pulling force of position spring opposite end cap will hold cap to be pushed out with respect to tubular body axle, block head is moved from tubular body axial bore To the mouth of pipe, water hole is exposed in tubular body inner chamber, the ring between tubular body axial hole, end cap and tubular body is connected The water spray passage of hole for water spraying composition on chamber, end cap bottom surface, sprinkling fire.After the condition of a fire disappears, environment temperature declines, warming memory Alloy spring is bounced back, and return spring stretches, and end cap is returned to and blocks current position, preparation state is again at.

The positive effect of the present invention is：The end cap coordinated using tubular body and with it is remembered as basic building block, and by warming Recall the cooperation of alloy spring and return spring under different temperatures environment, change the relative position between tubular body and end cap, The switching in water route is controlled, can quickly suppress the early stage condition of a fire, realizes that the temperature control of shower nozzle repeats to open and close automatically, advantageously ensures that and disappear The safe and reliable operation of anti-system, it is possible to reduce energy resource consumption.

Brief description of the drawings
