Description
Technical field
A kind of automatic fire valve with hand gear belongs to fire-fighting automatic control equipment field, is applied to fire-fighting, cooling system.
Technical background
Existing fire plant technology is divided into automatic sprinkling and manually opens two kinds of sprinklings by working method.Automatically working method generally adopts fixed installation, glass envelope formula spray head commonly is installed on the room furred ceiling in building, this glass envelope formula water spray head is when indoor environment temperature increases rapidly, can force glass envelope to break, the fire water that is connected with glass envelope just sprays and descends, and suppresses spreading of the condition of a fire.The defective of this spray equipment is after the condition of a fire is extinguished, and still water spray is more than, can cause serious consequence to some scene; Another defective is to be easy to break glass envelope in transportation, keeping, installation process, this in addition fire plant only is adapted at using in the large-scale building, can only be fixed installation, be not suitable in some small-sized systems, installing that for example use in places such as family, general shop, office.What manual fire plant was common is exactly fire extinguisher, and the advantage of fire extinguisher is to use comparatively flexible, and having only the people is the positive opening valve, fire-fighting liquid could spray and go out, reach the purpose of fire extinguishing, but defective is an acquisition environment variation of temperature automatically, more can not work automatically.
Summary of the invention
Purpose of the present invention provides the automatic fire valve of being with hand gear.
Technical scheme of the present invention is achieved like this: device is made up of the temperature-sensitive opener and the man-operated mechanism of valve body, valve, and described valve body mainly is made up of valve body, valve gap, diaphragm, spool; The step of one annulus flute profile is arranged in the inner chamber of described valve body, and the upper surface of step is equipped with diaphragm, and a relief hole is arranged in the middle of the diaphragm, diaphragm by valve gap by with being connected of valve body, tightly be pressed on the upper surface of cannelure step; On the described valve gap valve core cap is installed, between valve core cap and the valve gap sealing ring is arranged, locking member tightly is pressed in valve core cap on the upper surface of valve gap by screw thread, and spool is inserted in the valve core cap; Described spool is made up of the sealing gasket that is embedded in magnetic post in the copper sheathing and copper sheathing bottom; Described temperature-sensitive opener, by the collet that is enclosed within the valve core cap outside, the temperature-sensitive element that the collet outside is with, the magnet ring cover that withstand the collet upper surface, the magnet ring of installing in the magnet ring cover is formed, and the top of described magnet ring cover is connected with connector by screw thread, the outside of connector is with return spring, the interior upper surface of bonnet is withstood in the upper end of return spring, and the lower end withstands on magnet ring and puts, and described temperature-sensitive element is the temperature memory alloy of spring-like; Described man-operated mechanism is slidingly connected by the screw thread of connector upper end and the screw thread on the bonnet and forms; during the screw thread of rotating connector upper end; can drive the magnet ring that links to each other with connector moves up and down; opened by accident for fear of man-operated mechanism; upper end at connector is equipped with protective cap, and protective cap is connected with bonnet by screw thread.The principle of valve is work like this, the present invention is installed in after the scene, when environment temperature just often, the temperature memory alloy is in contraction state, this moment, the magnet ring cover is pushed down and withstood to return spring to collet, because the coupling of the magnetic post in the spool in magnet ring and the valve gap, also promoted motion under the spool, the sealing gasket of spool bottom blocks the relief hole on the diaphragm, under the acting in conjunction of high pressure fire fighting liquid, diaphragm tightly is pressed on the step of the annulus flute profile in the valve, and this moment, valve export did not have the ejection of fire-fighting liquid.When the valve environment generation of living in condition of a fire, temperature anomaly raises and when surpassing the operating temperature of memorial alloy, spiral helicine memorial alloy is rapidly along linear expansion, and promotion magnet ring cover moves upward, when forcing return spring to shrink, magnet ring moves upward by the magnetic post that magnetic coupling interaction drives in the spool, forces the sealing gasket of spool bottom to leave relief hole on the diaphragm, and the fire-fighting liquid of high pressure is gushed through valve export.After the condition of a fire was removed, when the temperature around the valve dropped to the reset temperature of memorial alloy, memorial alloy returned to original contraction shape memory; Under the effect of elastic restoring force, return spring promotes the magnet ring cover and moves downward, and the magnetic post that magnet ring drives again in the spool moves downward, and sealing gasket blocks relief hole again, is turned off at the high pressure effect lower valve of fire-fighting liquid.The present invention is as being installed on the mobile fire extinguisher; when the condition of a fire that takes place not around the valve time; can artificially protective cap of the present invention be taken away; the upper end of turn connector, the castering action during owing to screw thread rotation forces the magnet ring cover to move upward; the magnetic post that magnet ring drives in the spool moves upward; valve is opened, and when the needs valve-off, only needs the connector of turn in the other direction to get final product.
The invention has the beneficial effects as follows that valve can be opened automatically according to predefined operating temperature, the action of valve opening and closing is without any need for external impetus; The manually opened function of valve is given and to be used and maintenance brings convenience.Owing to use flexibly, be suitable for very much in mini-system, installing.The present invention also can use in cooling system.
