The invention has the beneficial effects as follows that sensor and valve can be installed separately, when having realized the automatic open close of spraying system of fire fighting, without any need for outer power.
Description of drawings
Among the figure, 1 steel wire protection cover, 2 steel wires, 3 return springs, 4 interlock covers, 5 spools, 6 magnet rings, 7 valve bodies, 8 magnetic posts, 9 regulate cover, and 10 regulate bolt, 11 valve core housings, 12 valve bonnets, 13 back-up rings, 14 temperature memory alloys, 15 fixation with steel wire framves, 16 sender unit caps; The fire water flow path direction is seen arrow among the figure.
The specific embodiment
Accompanying drawing is the principle assumption diagram of present embodiment.Device mainly comprises steel wire protection cover (1), steel wire (2), return spring (3), interlock cover (4), spool (5), magnet ring (6), valve body (7), magnetic post (8) is regulated cover (9), regulate bolt (10), valve core housing (11), valve bonnet (12), back-up ring (13), temperature memory alloy (14), fixation with steel wire frame (15), sender unit cap (16); Wherein regulate cover (9), regulate bolt (10), memorial alloy (14), fixation with steel wire frame (15), sender unit cap (16) is formed temperature sensor; Return spring (3), interlock cover (4), spool (5), magnet ring (6), valve body (7), magnetic post (8) valve bonnet (12) is formed the mechanism for opening/closing of spray valve, and the water inlet of valve is connected with the fire water network, and delivery port can be connected with various spray heads; Sensor and valve can arrange to be installed in different places and position that both connect by steel wire (2) according to the needs at fire-fighting scene; Valve body has delivery port in (7), and delivery port cooperates the unlatching that realizes valve with the piston of the bottom of spool (5) or closes, and spool (5) is installed in the valve core housing (11), and valve core housing (11) is sealed on the valve body (7), medium and the sealing of extraneous complete mechanical; The outside of valve core housing (11) is with magnet ring (6) assembly, the top of magnet ring (6) assembly is installed in the interlock cover (4), return spring (3) is withstood in the top of interlock cover (4), valve bonnet (12) is withstood in the top of return spring (3), the steel wire (2) that is enclosed within the steel wire cover (1) passes steel wire cover back-up ring, valve bonnet (12), return spring (3), interlock cover (4), adjusting bolt are fixed by the fixation with steel wire frame; The other end of steel wire (1) is passed steel wire cover back-up ring (13), sender unit cap (16), temperature memory alloy (14), regulates cover (9), regulates bolt (10), is fixed on the fixation with steel wire frame (15); Regulate cover (9) and be slidingly connected with sender unit cap (16), an end of memorial alloy (14) is withstood in the top of regulating cover (9), and the other end of memorial alloy (14) withstands the inner face of sender unit cap (16).
Structural principle of the present invention is work like this, when not having the condition of a fire to take place at ordinary times at the scene, be environment temperature just often, because the effect of the elastic restoring force of return spring (3), force interlock cover (4) to be in leftmost position in the accompanying drawing, and compressing magnet ring (6) assembly is shifted to leftmost position, under magnetic coupling interaction, magnet ring (6) forces magnetic post (8) assembly to move to Far Left, since magnetic post (8) assembly be installed in spool (5) above, so spool (5) also moves to leftmost position, the piston of spool (5) bottom is with the delivery port shutoff in the valve body (7), and the fire-fighting medium can not be through the outlet ejection of valve.When the environment temperature around the sensor surpasses the deformation temperature value of temperature memory alloy (14), being made into spiral helicine temperature memory alloy (14) deformation at once expands, the thrust that produces promotes to regulate cover (9) and moves to the left end of accompanying drawing, regulating cover (9) is moved to the left in the process, pulling steel wire (2) is moved to the left, the mobile interlock cover (4) that drops in the valve of steel wire (2) moves right, in interlock cover (4) moving process, driving magnet ring (6) assembly in compression return spring (3) moves right, magnet ring (6) drives magnetic post (8) again, spool (5) moves right, force the piston of spool bottom to leave delivery port on the valve body (1), valve open, fire water sprays through mouth spray; After the condition of a fire is extinguished, temperature around the sensor drops to the deformation temperature of memorial alloy (14) when following, memorial alloy (14) returns to original contraction state at once, return spring (3) in the valve is under the effect of elastic restoring force at this moment, promoting interlock cover (4) is moved to the left, magnet ring (6) drives magnetic post (8) again, spool (5) is moved to the left, and piston is the interior delivery port of shutoff valve body again, valve closing.
