Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 5, the fire-fighting water mist head has a connection part for connecting the spout part to a fire-fighting pipe and a spout part. The connecting part is of a columnar structure, can be cylindrical or in a straight prism shape, and is internally provided with a pipeline which is communicated along an axis. The spouting portion includes a cylindrical body section having a side elevation extending in the axial direction and an inclined section, the cylindrical body section being in the shape of a cylinder or a right prism. The inclined section is in a circular truncated cone shape or a prismatic table shape, and the circular truncated cone shape or the prismatic table shape is provided with inclined side faces. The end face of the end with the larger area of the inclined section is fixedly connected with the bottom surface of the cylindrical part, and a plurality of nozzles which are arranged at equal angles are formed on the inclined side surface. The cross-sectional area of the nozzle portion cylinder section is larger than that of the connecting portion, and the connecting portion is fixedly connected with the top surface of the cylinder portion.
Referring to fig. 1-5, a nozzle protection cover includes a housing 1, where the housing 1 includes a bottom plate and a sleeve, the sleeve has an inner side wall parallel to a side elevation of a nozzle spout section cylinder section, an annular groove is formed on the inner side wall of the sleeve, and a sealing ring 2 is arranged in the annular groove; the inner side wall of the sleeve is attached to the side face of the spout portion cylinder section.
After the spray head protective cover is installed, a gap exists between the surface of the bottom plate and the bottom end of the spray head.
In an alternative embodiment, as shown in fig. 3, one end of the casing 1 casing is directly connected to the bottom plate surface, i.e. the casing 1 casing side plate wall is perpendicular to the bottom plate surface. The inclined section of the spray head is partially surrounded in a closed space by the sleeve and the bottom plate of the shell 1, so that the isolation of external dust and corrosive positions from the spray nozzle is ensured.
In another alternative embodiment, the casing 1 casing side plate and the bottom plate are not directly connected, the end of the casing and the bottom plate are connected together through a connecting section, the connecting section extends from the casing bottom end to the plane of the bottom plate, the section diameter of the connecting section is gradually reduced from the casing bottom end to the bottom plate, the inner diameter of one end of the connecting section connected with the casing is consistent with the inner diameter of the casing, and the inner diameter of the end of the connecting section connected with the bottom plate is consistent with the diameter of the bottom plate. Further, the inner side wall of the connecting section is approximately parallel to the spray head inclined section.
The sealing ring 2 is arranged in the annular groove, has no folds and distortion and is uniformly attached to the annular groove.
After the sealing ring 2 is arranged in the annular groove, the sealing ring 2 is extruded and deformed, and the shell 1 and the sealing ring 2 are tightly attached to the fire-fighting fine water mist spray head by the tension of the sealing ring 2 and cannot easily fall off.
Further, in order to improve the sealing between the protective cover housing 1 and the spray head, more than one annular groove and sealing ring 2 may be provided on the inner side wall of the sleeve.
In order to ensure the fitting contact of the sleeve side plate of the casing 1 with the nozzle throat cylindrical section, the sum of the length of the inner side wall of the portion of the sleeve side plate in direct contact with the nozzle throat cylindrical section and the width of the annular groove is not less than 2 times, preferably 5 times, the width of the annular groove.
Further, to ensure that the protective cover case 1 can be smoothly separated from the nozzle when the nozzle is in operation, the sum of the length of the inner side wall of the sleeve in direct contact with the cylindrical body section of the nozzle portion of the nozzle and the width of the annular groove is not greater than the length of the cylindrical body section of the nozzle portion.
In fig. 4, an alternative embodiment is shown of the internal structure of the combination of the sprinkler head and the protective cover before the sprinkler head starts to discharge under pressure after assembly with a fire fighting water mist sprinkler head and before the protective cover shell has been removed. After the fire-fighting water mist spray head starts to work, a large amount of liquid is contained in the shell 1 in a short time, the pressure in the shell 1 is rapidly increased due to the sealing effect of the sealing ring 2, the bottom of the shell 1 is subjected to pressure, the side wall of the shell 1 is deformed due to radial pressure, finally, the shell 1 is separated from the spray head under the pressure effect, and the water mist sprayed by the water mist spray head starts to extinguish fire.
The shell 1 can be made of stainless steel corrosion-resistant materials or nylon and other elastic materials. The sealing ring 2 is preferably made of high-temperature-resistant and ageing-resistant fluororubber materials, so that the service life of the protective cover is prolonged.
The shell 1 is preferably made of elastic plastic which is easy to deform such as rubber, and when the sprayer works, the shell deforms due to the water pressure generated by the sprayer, so that the shell 1 can fall off from the sprayer.
In FIG. 5, the moment when the fire-fighting water mist head of this example comes off after assembly is shown.
The foregoing description and description of the embodiments are provided to facilitate understanding and application of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications can be made to these teachings and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. The present invention is not limited to the above description and the description of the embodiments, and those skilled in the art should understand that the modifications and changes made without departing from the scope of the present invention.
