Description
A kind of vertical type one inlet and multi-exit fire-fighting spraying valve, belongs to fire-fighting, cooling automatic control equipment field.
Background technique
Existing fire-fighting spray device, a kind of is mounting glass bubble formula water spraying head on room furred ceiling in building, this glass bulb formula water spraying head is in the time that indoor environment temperature increases extremely, and glass bulb can push and break, the fire water being connected with glass bulb spraying head just spray and under.The defect of glass bulb mounting type is, because glass bulb must expose, so glass bulb easily breaks; After use, can not reset, current are more than.After fire is extinguished, owing to can not automatically closing, water still sprays incessantly, when valuable water resources is wasted in a large number, also causes the loss of water logging.For example library, the laboratory of archives material chamber, outfit instrument and apparatus etc., all can form the secondary disaster due to a large amount of water loggings, cause the loss that is difficult to retrieve.After water spray, package unit can only be changed.Another problem is that unless destroyed glass bulb, no side manually can not be opened shower nozzle, and medium is flowed out.In addition, glass bulb formula fire-fighting system is a kind of fixing, permanently-installed, because its higher price can only be used in relatively high-grade building.
Another kind of spraying system of fire fighting in recent years, automatic fire control shower valve is marmem, produces deformation after sense temperature, utilizes the power of deformation to open valve, when temperature recover after, under the tension force of bias spring by valve closing.The patented technology that past has declared, the patent No. 200420093490.6,200710119537.X, 200810111803.9,201010611901.6 etc., although realized non-transformer automatic spray by magnetic coupling and temperature memory alloy combination structure, but because the continuous motion stem that drives magnet ring is limited by the boundary dimension of valve gap and piston sleeve, in original design, memory alloy needs relatively large diameter dimension, reduce the thrust in deformation process, caused valve sometimes not opened.Another one subject matter is because valve body structure is straight-through type one-in-and-one-out type, memory alloy and bonnet etc. can only be vertical with valve body, be difficult to the valve body part of valve to be arranged on room furred ceiling top (water receiving pipe), the thermal sensible elements such as memory alloy to be arranged on to the below of furred ceiling, install vertically downward, feel more fast ambient temperature.When the more shower nozzle of space requirement that area is slightly large, the valve of former direct-passing mode multiple shower nozzles of can only connecting, cannot be installed in parallel, for example, when valve outlet has been installed shower nozzle, when the other end of valve also needs mounting spray head, can only be after the shower nozzle of valve outlet installs, then by serises connecting tube around to the other end mounting spray head or connect again in addition a valve.So be the impact that the power of water-outlet quantity, memory alloy and mounting type are all subject to valve shape, limit greatly application.Therefore all Chinese's oneself invention can not be substituted to pool for many years and carry out glass bulb fire prevention, fire-fighting new technology, should wider applying.For reaching the object of installing into having more temperature-sensitive final controlling element (memory alloy) downwards, when making valve outlet mounting spray head; Can multiple shower nozzles in parallel; And the power of memory alloy is unaffected.The inventor once applied for a patent (heat-collected rely on oneself automatic fire valve 201210164539.1), and in former design, piston and piston cap are two, therefore cause entrance pressure and pressure release not to stablize; Because entrance pressure hole and water inlet are a position, close very difficultly, simultaneously small piston control relief hole is under the direct effect of intake pressure, to close need to be larger strength, implement very difficult.This patent is integrated piston and piston cap, simultaneously to entrance pressure and.Larger variation has been done in the position of pressure release, and the water knockout drum of valve inner also changes bypass water inlet into by original directly water inlet, more accurate and convenient to ensure.
