Please refer to Fig. 1-5, a kind of vibration induction detects fire-fighting spraying head, including nipple joint 1, yoke arm frame 2, splash box 3,
Vitreum 4 and fastening screw 5, yoke arm frame 2 are two symmetrical struts, and yoke arm frame 2 is cut off wherein, if two sections and
Every section is all provided with internal screw thread cylinder, and two sections of thread barrels are threaded in the both ends of vibration detection device 6 respectively, vibration detection device 6 by
Tightening support arm 61, solenoid 62, bar permanent magnet 63, pressure transmission sealing element 64, back stop 65 and pipeline indicator light 66 form, and two sections
It is threadedly coupled respectively with the both ends of tightening support arm 61 in internal screw thread cylinder, the inner wall of the lower lumen of tightening support arm 61 is stained with helical
Circle 62, and the inner cavity of tightening support arm 61 is equipped with bar permanent magnet 63, the top of bar permanent magnet 63 passes through back stop 65 and tightening
The top of 61 inner cavity of support arm is fixedly connected, and the bottom end of tightening support arm 61 is equipped with pressure transmission sealing element 64, and pressure transmission sealing element 64 is used for
Hydraulic pressure shock surface is accepted, the lateral wall of tightening support arm 61 is equipped with pipeline indicator light 66, and pipeline indicator light 66 is concatenated with solenoid 62
In the closed circuit, pipeline indicator light 66 is LED light or neon bulb indicator light, and the top of 1 inner cavity of nipple joint is equipped with detection
The top of sink 7, detection sink 7 is connected to the lower thread tube inner chamber of yoke arm frame 2, the top outside nipple joint 1 and is located at
The lower part of another yoke arm frame 2 offers installation card slot 8, and installation card slot 8 and the yoke arm frame 2 at this are clamped using T-slot,
In, pressure transmission sealing element 64 further includes sealing ring 64a and pressure transmission film 64b, sealing ring 64a are annulus, a length of tightening branch of inner ring diameter
The intracavity diameter of arm 61, outer ring path length are less than the outer dia of tightening support arm 61, and pressure transmission film 64b is water-fast rubber membrane, pressure transmission
The inner ring of film 64b sealing sealing ring 64a, wherein back stop 65 is tension spring in sagging type, is spring in erect type.
Above equipment completes installation as a result, that is, the top of tightening support arm 61 is now fully screwed into the top of a yoke arm frame 2
In section thread barrel, and pressure transmission sealing element 64 is placed in the lower section of tightening support arm 61, then by the bottom end of another yoke arm frame 2 from peace
It is loaded in the opening slide-in installation card slot 8 of slot 8, then makes the lower section screw thread of one yoke arm frame 2 of lower end aligned of tightening support arm 61
Cylinder, at this point, pressure transmission sealing element 64 is still placed in the lower section of tightening support arm 61, then turns tightening support arm 61, so that tightening support arm 61
Lower part progress into the lower section thread barrel of the yoke arm frame 2, finally, under the lower flange of tightening support arm 61 and yoke arm frame 2
Contact at the top of section thread barrel, pressure transmission film 64b will test the end of sink 7 by being pressed at the port of tightening support arm 61 and detection sink 7
Mouth seals up, and recalibration vitreum 4 turns fastening screw 5.
Wherein, the top thread barrel depth of yoke arm frame 2 is 1.5~2 times of its underpart thread barrel depth, on the one hand, so that
When the top of tightening support arm 61 is fully screwed into the top thread barrel of yoke arm frame 2, the lower end of tightening support arm 61 can remove yoke arm
In the lower thread cylinder of frame 2, on the other hand, when the lower end of tightening support arm 61 is fully screwed into the lower thread cylinder of yoke arm frame 2, tightly
The top for determining support arm 61 still has one section of screw thread to be located in the top thread barrel of yoke arm frame 2, and solid stability is twisted in guarantee, meanwhile, yoke
The top thread barrel of cantilever crane 2 is identical with the screw thread in lower thread cylinder, section and thread pitch including screw thread, to protect
Demonstrate,proving being capable of synchronizing moving when tightening support arm 61 rotates.
Wherein, when bar permanent magnet 63 opens pressure transmission film 64b completely, the other end of bar permanent magnet 63 is stretched or compression is fixed
Elastic force caused by the spring 65 of position is exactly equal to the gravity of bar permanent magnet 63, it is contemplated that the requirement to fire-fighting pipeline flow degree,
Can the initial elasticity power suitably to back stop 65 be adjusted.The principle of the application detection is based on the water supply for changing fire pump
Pressure, if fire main is unobstructed, that is, the differential water pressures changed can be acted on completely on pressure transmission film 64b, so according to the differential water pressures
The initial elasticity force value for setting back stop 65, it is non-fully obstructed if causing that water route narrows for local stoppages in fire extinguisher canvas hose
The case where, that is, the differential water pressures changed can not be reached completely on pressure transmission film 64b, and the initial elasticity force value of back stop 65 is complete as a result,
For balancing the self weight of bar permanent magnet 63, as long as then generating differential water pressures on pressure transmission film 64b, that is, it may make that bar permanent magnet 63 is dynamic
Make, pipeline indicator light 66 is lighted；If it is desired to which water route is completely unobstructed, that is, require the initial elasticity force value of back stop 65 except balance bar shaped
Outside the self weight of permanent magnet 63, there are also having more than needed, which acts on pressure transmission film 64b lower than differential water pressures are preset
The pressure of upper generation, when without detection, which is carried by pressure transmission film 64b.
Application method of the invention is as follows:
Change the pressure of supply water of fire pump, smooth fire extinguisher canvas hose can receive differential water pressures, and hydraulic pressure passes through detection sink 7
Pressure transmission film 64b is impacted, the depth that bar permanent magnet 63 enters in solenoid 62 is pressed, to change the magnetic flux across solenoid 62
Amount, so that generating induced current in solenoid 62, pipeline indicator light 66 issues the of short duration flashing of light, that is, illustrates that the pipeline is unobstructed,
Otherwise, pipeline blockage.
