Abstract
The autoamtic magentic control shower valve comprises magnetic controlled pilot valve and shower valve, and the interior of magnetic control pilot valve comprises magentic ring, magnetic core, temp. marmen, small piston component and large piston component. When the fire is happened in the field, the temp. marmen is deformed, the magentic control pilot valve is opened and the shower valve also is opened. When the fire is extinguished, the marmen is restored to original state, and the magnetic control pilot valve and shower valve are closed, and restored to wating state.
Description
A kind of automatic magnetically controlled showering valve belongs to fire-fighting watering equipment and makes the field.
Fire-fighting is with in the automatic sprinkler fire-extinguishing system, and drench valve is a critical piece wherein, in the prior art, uses kind a lot, as double plate valve core type, diaphragm type, piston type etc.And the effect of drench valve in water system is when the condition of a fire takes place, under the commander of fire control system, open magnetic valve, or the glass envelope fragmentation, or the molten metal molten of office, pressure releases, thereby open main valve automatically, reach purpose, but the drench valve of the sort of form no matter to the pipe network output hydraulic pressure that drenches with rain, prior art all can not be after the condition of a fire be extinguished, automatically close, stop to pipe network water supply, during by its non-transformer, can not stop automatically especially supplying water.Therefore in the scene of fire, after the condition of a fire is extinguished, still spray water incessantly in the scene, up to the people for closing, till the water route.Cause the serious waste of water resource and the difficulty of work of treatment afterwards, this problem is that the fire protection professional craves for the difficult problem of solution always for many years.
The invention provides a kind of technical scheme of automatic magnetically controlled showering valve, the present invention need not electric power as signal and power source, when the condition of a fire takes place in the scene that the technical program is installed, drench valve need not the artificial commander of any way, just can move to the detection of scene temperature according to self, Open valve provides the water source to the spray net, automatic-closing valve again after the condition of a fire is extinguished recovers stand-by state.
The enforcement of design principle of the present invention and technical scheme is to realize like this.The present invention is made up of the magnetic control pilot valve of automatic operation type and the drench valve of main water system, its basic principle is that the magnetic control pilot valve is by temperature is detected automatically, and the magnetic control pilot valve is opened or closed to the control magnetic switch, to reach when the magnetic pilot valve is opened, pressure in the control chamber in the drench valve is by pressure release, the drench valve spool produces pressure reduction up and down, force spool to move to control chamber, Open valve reaches the purpose of water supply, when the detected environment temperature of magnetic control pilot valve is lower than design temperature, the magnetic control pilot valve is closed, force the rapid build-up pressure of control chamber of drench valve, make spool up and down the pressure at two ends equate that this moment, spool moves down closed the water route under return spring and the effect of import hydraulic pressure.The detection of temperature and reaction.Adopt the temperature shape memory alloy environment temperature to be detected and makes corresponding action, design medium sensitivity in the present invention and can regulate.Pilot valve utilizes magnetic core, magnet ring, and two-stage piston valve control principle, reliable in action, accurately, reaction speed is rapid.Pilot valve can be designed to the temperature shape memory alloy is installed within it, directly pilot valve is installed in the scene, and connects with drench valve with pipeline, also can directly be installed in the scene to the temperature shape memory alloy as sensor.
Be that the temperature shape memory alloy is installed in the embodiment in the pilot valve below, and (1) (automatic magnetically controlled showering valve system) accompanying drawing (2) (operation type magnetic control pilot valve automatically) detail is set forth in conjunction with the accompanying drawings.Magnetic control pilot valve 1 in the accompanying drawing (1), return spring 2, spool 3, adjustable pipe 4, spool delivery port 5, valve body 6, relief tube 7, water (flow) direction such as arrow, magnetic control pilot valve 1. is to be in closed condition at ordinary times, pressure in the control chamber at return spring 2 places equates (delivery port pressure less than above both) at this moment with import hydraulic pressure, under the effect of return spring, spool 3. moves down, and under the acting in conjunction of import hydraulic pressure, seal delivery port, close main water route.When the magnetic control pilot valve is opened, liquid in the control chamber at return spring place is by 1 pressure release of relief tube 7 magnetic control pilot valves, pressure in the control chamber is less than import hydraulic pressure pressure, spool 3 forms pressure reduction (this pressure reduction can come chamber system by the needle-valve of regulating on the adjustable pipe 4) up and down, Open valve, current direction spray webmaster.After the condition of a fire was extinguished, the magnetic control pilot valve was closed, and the control chamber internal pressure is set up rapidly, and the pressure differential in water inlet pressure and the control chamber is zero, and spool is closed the water route rapidly under return spring and the effect of import hydraulic pressure, recovered stand-by state.In the accompanying drawing (2), the magnetic control pilot valve is by regulating cover 16, return spring 17, magnet ring 18, valve piston assembly 19, big piston assembly 20, sealing ring 21,22,9, valve body 8, connector 10, temperature shape memory alloy 11, magnetic core 12, piston bush 13, temperature-sensitive chamber 14, hydraulic pressure through hole 15 is formed.Under normal temperature, because the effect of hydraulic pressure through hole 15, hydraulic pressure forces big piston assembly 20 to seal the valve body intake-outlet at ordinary times, and valve is in closed condition.When the scene has the condition of a fire to take place, environment temperature rises rapidly, when reaching the deformation temperature of memorial alloy 11, memorial alloy 11 rapid deformation elongations, because its underpart heads on connector 10, upwards elongation of memorial alloy 11, promote magnet ring 18 to top offset, the displacement of magnet ring 18 drives magnetic core 12 and moves upward, and this moment, magnetic core place inner chamber communicated with atmosphere by the centre bore in the valve piston assembly 19, hydraulic pressure is at the pressure reduction of formation up and down (hydraulic pressure is greater than atmospheric pressure) of valve piston assembly 4, valve piston assembly 19 moves up, and water in the chamber is because valve piston 19 moves when big piston assembly 20 upper port form the slit releases, because after water releases, what make big piston assembly 20 forms pressure reduction with upper port on every side, force big piston assembly 20 to top offset, open pilot valve, drench valve is opened.After the on-the-spot condition of a fire is extinguished, when environment temperature drops to normal temperature, temperature shape memory alloy 11 shrinks, returns to original state, because the elastic restoring force of return spring, magnet ring 18 is moved down, driving magnetic core 12 moves down, seal valve piston assembly 19 upper port, and drive the upper port that valve piston assembly 19 is sealed big piston assembly 20, force big piston assembly 20 upper ends, because hydraulic pressure is set up in the effect of hydraulic pressure through hole 15 rapidly, hydraulic pressure forces big piston assembly 20 to move rapidly, close pilot valve, finish once action, return to stand-by state.Use thread connection between pilot valve body 8 and the adjusting cover 16, regulate the susceptibility that screw thread can be regulated temperature deformation memorial alloy 11.
