Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-2, an explosion-proof fire sprinkler head in winter comprises a spray pipe 1, a water inlet pipe 2 is embedded in the spray pipe 1 in a sealing manner, a splash pan 3 communicated with the interior of the spray pipe 1 is installed at the lower end of the spray pipe 1, a plurality of through holes 6 are formed in the lower end of the spray pipe 1, and the splash pan 3 is communicated with the interior of the through holes 6.

The interior bottom fixedly connected with cushion 19 of spray tube 1, the embedded water-stop sheet 4 that is equipped with of spray tube 1, and the lower extreme of water-stop sheet 4 is through bursting 5 fixed connection bottom in spray tube 1 on the spray tube 1 inner wall seted up recess 17, and recess 17 is located the below of water-stop sheet 4. It should be noted that, by providing the pad 19, after the bursting tube 5 is burst by heat, the water-stop sheet 4 can fall on the pad 19 and be located in the middle of the groove 17, so that water flows out through the groove 17 and flows to the water-spraying disc 3 through the through hole 6 to perform fire extinguishing by spraying water.

Spout 9 has been seted up to the lateral wall of spray tube 1, and one-way apopore 13 has been seted up to the lateral wall of inlet tube 2, and one-way apopore 13 makes water can only one-wayly flow to one-way apopore 13 from spray tube 1 in, installs the drainage device to one-way apopore 13 drainage in the spout 9.

The drainage device comprises an iron piston 10 which is connected in the sliding groove 9 in a sealing and sliding mode, a one-way air outlet hole 12 communicated with the inside of the sliding groove 9 is formed in the inner wall of the spray pipe 1, the one-way air outlet hole 12 limits air to flow to the spray pipe 1 from the sliding groove 9 in a one-way mode, a one-way air inlet hole 18 is formed in the inner wall of the sliding groove 9, and the one-way air inlet hole 18 only allows air to flow to the sliding groove 9 from the one-way air inlet hole 18. It should be noted that, when the unidirectional water outlet hole 13, the unidirectional air outlet hole 12 and the unidirectional air inlet hole 18 are actually manufactured, only the unidirectional valve is installed in the holes, and the unidirectional water draining and exhausting functions can be realized. In addition, when the piston 10 and the sliding plug 14 move downwards, part of the water is discharged from the one-way water outlet hole 13 by the sliding plug 14, and meanwhile, the piston 10 moves downwards to continuously blow air to the sliding plug 14 and the water stop plate 4, so that the water between the sliding plug 14 and the water stop plate 4 is discharged partially again and is replaced by air, and therefore, the amount of the water between the sliding plug 14 and the water stop plate 4 is greatly reduced, and a mixture of water and air is formed (as shown in fig. 2).

Further, when the piston 10 and the sliding plug 14 move upward, air can enter the chute 9 along the one-way air inlet hole 18 and enter the space between the water stop plate 4 and the sliding plug 14 for supplement through the one-way air outlet hole 12, so that the sliding plug 14 and the piston 10 can both move upward smoothly.

The sliding plug 14 of magnetism system is connected with in the inlet tube 2 to sealed sliding, and water-stop sheet 4 upper end fixedly connected with water-stop column 15, and water-stop column 15 is sealed to run through sliding plug 14, and a plurality of blind holes 16 are seted up to water-stop column 15's lateral wall, and the degree of depth of blind hole 16 is greater than sliding plug 14's thickness. Evaporating chamber 7 has been seted up to the lateral wall of spray tube 1, install the actuating mechanism that drive piston 10 removed in evaporating chamber 7, actuating mechanism includes sealed sliding connection at the push pedal 8 in evaporating chamber 7, evaporating chamber 7 intussuseption is filled with the evaporating liquid, and is concrete, the evaporating liquid can adopt the ether that the boiling point is about 34 degrees, can liquefy earlier in the former rate of water icing winter, and make drive structure and drainage device operation, discharge water, make burst pipe 5 cracked after effectively preventing to freeze in the spray tube 1 water, in addition the ether is stored in inclosed evaporating chamber 7, can not take place to leak and produce danger. The push plate 8 is fixedly connected with the piston 10 through a connecting rod 11.

In the use process of the device, in seasons with higher temperature or in fire, the evaporated liquid is in a gaseous state, the push plate 8 is pushed to move upwards to a higher position, the piston 10 is at the higher position, and the magnetic sliding plug 14 is attracted by the iron piston 10 to be at the higher position, as shown in figure 1. And because the depth of the blind hole 16 is greater than the thickness of the sliding plug 14, water in the water inlet pipe 2 can flow into the spray pipe 1 through the blind hole 16, when a fire occurs, the bursting pipe 5 bursts, the water-stop plate 4 moves downwards to the bottom in the spray pipe 1 after losing support and is supported by the cushion block 19, at this time, water in the water inlet pipe 2 flows into the spray pipe 1 through the through hole of the sliding plug 14, and water in the spray pipe 1 can flow to the through hole 6 through the groove 17 and flows out from the splash plate 3 to spray water for fire extinguishment (refer to fig. 2).

In winter with lower temperature, the evaporated liquid is condensed into liquid, the volume is reduced, the push plate 8 can be pushed by atmospheric pressure to move downwards, and the piston 10 and the sliding plug 14 are synchronously driven to move downwards. In the downward moving process of the piston 10 and the sliding plug 14, when the sliding plug 14 moves downward below the blind hole 16, the sliding plug 14 and the water-stop column 15 form a seal to block the water inlet pipe 2 from the spray pipe 1, and when the piston 10 moves downward, air can be discharged between the sliding plug 14 and the water-stop plate 4 along the one-way air outlet 12, so that water between the sliding plug 14 and the water-stop plate 4 is discharged along the one-way water outlet 13, the water quantity between the sliding plug 14 and the water-stop plate 4 is greatly reduced, and even if the water between the sliding plug 14 and the water-stop plate 4 is condensed into ice, extrusion force cannot be generated on the water-stop plate 4 and the bursting tube 5 below, so that the water freezing volume can be prevented from expanding to cause the bursting tube 5 to burst and the failure of the fire sprinkler head can be prevented.

When the weather is warmed up again, the evaporated liquid is evaporated into gas again, the push plate 8, the piston and the sliding plug 14 are pushed again to move upwards and reset, the sliding plug 14 is located between the blind holes 16, the water body in the water inlet pipe 2 can flow into the spray pipe 1 through the blind holes 16, and the fire-fighting spray head can act when a fire disaster occurs.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
