Abstract
The invention relates to an automatic-spraying and temperature-controlling valve provided with an early-warning device and pertains to the field of flow automatic control equipment. The valve of the invention is characterized in that a valve core component consists of a valve core cap, a valve core, a piston part, a membrane, a reset spring and an upper interlocking rod; a spraying and temperature-controlling head consists of a spraying cover, a sealing part, a lower interlocking rod, a temperature-controlling memory alloy, a moving board with a magnet body, a magnetic switch, an early-warning memory alloy and a bottom cover. When the ambient temperature abnormally increases, the early-warning memory alloy acts to drive the magnetic switch to output a warning signal and if the temperature continuously increases, the temperature-controlling memory alloy acts to open the valve and then fire water sprinkles in a rotary way and automatically stops sprinkling after temperature drops.
Description
Technical field
A kind of automatic spray temperature control valve with prior-warning device belongs to flow automatic control equipment field, is mainly used in fire-fighting system.
Technical background
Existing fire prevention, be that fume ionic sensor and glass envelope formula water spray head are installed in the room, the function of fume ionic sensor is after detecting a certain amount of smog automatically, send alarm signal to master control room, and glass envelope formula water spray head is an indoor environment temperature when increasing rapidly, glass envelope breaks, and the fire water that is connected with glass envelope just sprays and descends, and suppresses spreading of the condition of a fire.These two kinds of each architectonicals of fire-fighting system advantage is respectively arranged, but common defective all are uncorrelated mutually; Different defectives is that glass envelope formula water spray head can not turn-off the water source at the scene, more can not be after temperature reduce, and automatic-closing valve, after fire was extinguished, the glass envelope that breaks still water spilt incessantly, has wasted a large amount of precious water resource.And the defective of fume ionic sensor needs power supply when being work, for the continual work of low power heating wire, will waste much electricity year in year out.
Summary of the invention
Purpose of the present invention provides a kind of automatic spray temperature control valve with prior-warning device.
Technical scheme of the present invention is achieved like this; Scheme is made up of valve body, temperature control sprinkler head two parts, it is characterized in that in the body cavity, and a self-operated type core assembly is arranged, and core assembly is made up of valve core cap, spool, piston piece, diaphragm, return spring, last trace; The temperature control sprinkler head is made up of the movable plate that sprays cover, seal, following trace, temperature control memorial alloy, magnet carrier, magnetic switch, early warning memorial alloy, end cover; Valve core cap is connected with valve core by screw thread; Valve core is connected with valve body by screw thread; Valve body lower portion is connected with the sprinkling cover by bearing; The return spring upper end withstands on the inner bottom part of valve core cap, the lower end of return spring is enclosed within the top of piston piece, the outside of piston piece is with diaphragm, under the effect of return spring, piston piece in valve core upper end, and is sealed delivery port with pressing diaphragm, and a ring shaped slot is arranged at valve core top, the centre of ring shaped slot is a delivery port, has several water inlets to be communicated with the valve water inlet around the ring shaped slot; The bottom of piston piece is equipped with trace, the lower end of last trace is connected with the interior trace down of temperature control sprinkler head, lower connecting rod passes seal and sprays cover, the temperature control memorial alloy is installed in down the below of the plate washer of trace, the lower end of temperature control memorial alloy is pressed on the movable plate of magnet carrier, the lower surface of the movable plate of magnet carrier withstands on the top of early warning memorial alloy, and the lower surface of early warning memorial alloy is installed in above the end cover; Magnetic switch is installed in the outer top of the movable plate of magnet carrier, and has holding wire to be connected with the fire-fighting general control system; Temperature control memorial alloy, early warning memorial alloy have different temperature memory characteristics, and the operating temperature of early warning memorial alloy is lower than the temperature control memorial alloy; Spraying the cover side has two symmetries to spray mouth.After the present invention was installed in the scene, the water inlet on the valve was connected with the fire water pipe network; Under the normal temperature, because the effect of return spring, diaphragm tightly is pressed on the delivery port of spool by piston piece, though the lower end of last trace is connected with following trace in the temperature control sprinkler head, but owing to temperature control memorial alloy, early warning memorial alloy all are in contraction state, valve is in closed condition, and the movable plate of magnet carrier is below magnetic switch, magnetic switch is in the position of " opening ", does not have alarm signal to be transported to the control room; When the scene generation condition of a fire causes environment temperature to raise, the early warning memorial alloy at first expands deformation, and the movable plate that promotes magnet carrier moves up and close magnetic switch, and magnetic force makes the two poles of the earth closure in the magnetic switch, output alarm signal is in time taked the emergency measure with control system to hint; As this moment scene temperature also when rising and having reached the operating temperature of temperature control memorial alloy, the temperature control memorial alloy expands deformation at once, promote following trace, go up trace, piston piece and diaphragm upwards, under the acting in conjunction of hydraulic pressure, the diaphragm valve core delivery port that speeds away, fire water is from spraying the sprinkling mouth ejection on the cover, because valve body lower portion is connected with the sprinkling cover by bearing; When current spray by two sprinkling mouths, spray cover and just on valve body, rotate, reach better wideer spray effect.The installation of seal is closed and has been exempted from water and may flow on the temperature control memorial alloy, thereby has avoided the influence of water to detected temperatures.When environment temperature drops to set temperature value when following, the temperature control memorial alloy returns to original contraction state, and valve is closed again, blocks current, and sprinkling stops; If temperature further descends, the early warning memorial alloy also returns to original contraction state, and warning stops.
The invention has the beneficial effects as follows, install automatic testing environment variation of temperature, and can open warning system automatically according to predefined operating temperature value, when environment temperature further rises, valve open, the fire water of rotation is sprayed and is descended, after environment temperature descends, again can automatic-closing valve and close warning system, avoided the waste of water resource.The action of valve need be by any external impetus.
