Description
Technical field
A kind of intelligent fire valve device belongs to fire-fighting system self-extinguishing equipment field.
Technical background
Existing fire prevention, be that fume ionic sensor and glass bulb formula water spraying head are installed in the room, these devices not only can only be applied in higher building room, as hotel, restaurant, office building, and since structural reason, glass bulb formula water spraying head, it is a kind of disposable device that can not turn-off the water source, so after fire was extinguished, still water spilt incessantly, cause a large amount of wastes of water resources.Fume ionic sensor can only transmit alarm signal to fire-fighting system, during work power supply must be arranged, and needs to consume a certain amount of electric energy.These defectives do not overcome so far.
Summary of the invention
Purpose of the present invention provides a kind of intelligent fire valve device.
Technological scheme of the present invention is achieved like this: device mainly is made up of valve body, temp.-sensing head, it is characterized in that in the inner chamber of valve body, one spool is arranged, in the sleeve pipe that spool inserts in valve pocket with valve gap is connected, spool has magnet in the upper end, the spool bottom is connected with diaphragm, the water outlet on the moving up and down of diaphragm can open or close in the valve, and locking element is fixed on the spool bottom with diaphragm; Temp.-sensing head is made up of installation sleeve, interlock cover, magnet ring, thermosensitive element, reset spring, valve bonnet; Thermosensitive element is withstood in the installation sleeve upper end, and thermosensitive element is enclosed within outside the interlock cover; The interlock cover studs with magnet ring in the bottom, and is positioned in the installation sleeve, and the interlock cover can slide up and down outside the sleeve pipe on valve gap; Interlock puts the end and withstands reset spring, and the temperature-sensitive cover is withstood in the upper end of reset spring, and the temperature-sensitive cover is netted, and the lower end of temperature-sensitive cover can be connected with valve gap by screw thread; Thermosensitive element under the normal temperature is in contraction state, because the contention effect of reset spring, on installation sleeve, the magnet ring in the interlock cover pushes away magnetic post and spool in the valve gap sleeve pipe downwards by magnetic action with the compressing of interlock cover, and the compressing diaphragm is sealed valve outlet; When thermosensitive element by the temperature-sensitive cover, detect that ambient temperature rises and when reaching operating temperature, thermosensitive element generation deformation is expanded, promote the interlock cover and upwards compress reset spring, magnetic post, spool on the valve gap of magnet ring drive simultaneously move upward, and force diaphragm to leave water outlet, under the effect of hydraulic pressure, diaphragm is opened rapidly, flow through connectedness ejection of fire water, when ambient temperature drops to set temperature value when following, thermosensitive element returns to original contraction state, valve is closed again, blocks current.
The invention has the beneficial effects as follows, when installing the ANOMALOUS VARIATIONS of automatic testing environment temperature, can open automatically according to predefined operating temperature.After ambient temperature descends, again can automatic-closing valve.
Description of drawings
Accompanying drawing is the principle sectional view of this device.
Among the figure: 1 valve body, 2 diaphragm locking elements, 3 diaphragms, 4 seal rings, 5 magnets, 6 interlock covers, 7 thermosensitive elements, water outlet, 8 reset springs, stuffing box gland, 9 valve bonnets, 10 magnet rings, 11 installation sleeves, 12 valve gap sleeve pipes, 13 valve gaps, 14 spools, 15 water outlets, 16 links.Arrow among water (flow) direction such as the figure.
Specific embodiment
Accompanying drawing is made the specific embodiment of thermosensitive element for adopting the temperature memory alloy, installs by valve body (1) diaphragm locking element (2), diaphragm (3), seal ring (4), magnet (5), interlock cover (6), thermosensitive element (7), reset spring (8), valve bonnet (9), magnet ring (10), installation sleeve (11), valve gap sleeve pipe (12), valve gap (13), spool (14), water outlet (15), link (16) is formed.The top of valve body among the figure (1), by screw thread valve gap (13) is installed, valve gap sleeve pipe (12) is arranged on valve gap (13), in the inner chamber of valve body (1), one spool (14) is arranged, diaphragm (3) and diaphragm locking element (2), locking element (2) is fixed on diaphragm (3) bottom of spool (14), insert in the valve gap sleeve pipe (12) on the top of spool (14), spool (14) studs with magnet (5) in the upper end, the outside of valve gap sleeve pipe (12), be with installation sleeve (11), interlock cover (6) is installed in the installation sleeve (11), studs with magnet ring (10) in the interlock cover (6), interlock cover (6) is enclosed within valve gap sleeve pipe (12) outside, and can outside valve gap sleeve pipe (12), slide up and down, because the magnetic force of magnet ring (10) during slip, can drive the magnet (5) in the spool (14), promptly driving spool (14) moves up and down, spool (14) drives diaphragm (3), and moving up and down of diaphragm (3) can be opened or closing valve water outlet (15); The top of the outside of interlock cover (6), installation sleeve (11) is with thermosensitive element (7), interlock cover (6) top is with reset spring (8), the inner top of valve bonnet (9) is withstood on the top of reset spring (8), and valve bonnet has temperature-sensing net above (9), and the bottom of valve bonnet (9) is connected with valve gap (13) by screw thread; Under the normal temperature, thermosensitive element (7) is in contraction state, because the contention effect of reset spring (8), interlock cover (6) underpart is pressed on the bottom of installation sleeve (11), magnet ring (10) in the interlock cover (6), magnet (5) in the valve gap sleeve pipe (12) is pushed away downwards, force diaphragm (3) to seal valve outlet (15); When thermosensitive element (7) passes through valve bonnet (9), when detecting the ambient temperature rising and reaching operating temperature, deformation takes place and expands in thermosensitive element (7) immediately, because thermosensitive element (7) bottom has been withstood installation sleeve (11) bottom, deformation can only promote interlock cover (6) and upwards oppress reset spring (8), magnet ring (10) drives valve gap inner magnet (5) simultaneously, spool (14) moves up, force diaphragm (3) to leave water outlet (15), under the effect of hydraulic pressure, diaphragm (3) is opened rapidly, the current that have pressure are through link (16) ejection, and link (16) can be connected with standard spray nozzle, to reach better, wideer spray effect.When ambient temperature drops to set temperature value when following, thermosensitive element (7) returns to original contraction state, and valve is closed again, blocks current.
