The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1-4, the invention provides a transverse pressure bar type radiant heat starting spray head, which comprises a body 1 and a splash plate 2, wherein the body 1 is tubular and is provided with external threads for connecting with a water pipe.
The body 1 is connected with the splash box 2 through a spray head frame 9, the sealing seat 3 is installed at the water outlet end of the body 1, and a group of starting assemblies for starting the spray head are installed on the body 1.
Referring to fig. 1-4, the starting assembly of the present invention comprises a temperature sensing element 7, a cross pressing rod 5, two fixing hooks 8 and two oblique pressing rods 4.
The temperature sensing element 7 comprises two metal sheets which are mutually lapped, the lapped parts are welded by fusible solder (the solder is 74-degree alloy solder purchased by Shanghai chart novel welding materials Co., Ltd.), and the two metal sheets are respectively provided with a first through hole 71. The two ends of each fixing hook 8 are respectively a connecting end and a fixing end, the connecting end is fixed with the body 1, and the fixing end extends between the body 1 and the splash pan and is positioned on the outer side of the edge of the splash pan 2 in the horizontal direction; the middle part of the transverse pressure rod 5 is arranged on the sealing seat, and two ends of the transverse pressure rod respectively extend to the lower part of the fixed end of the fixed hook.
Referring to fig. 5, the miter bar includes an upper bent portion 41, a straight rod portion 42, and a lower bent portion 43, an included angle between the upper bent portion 41 and the straight rod portion 42 is an obtuse angle, an included angle between the lower bent portion 43 and the straight rod portion 42 is an acute angle, and specifically, the upper bent portion 41 and the lower bent portion 43 are both inclined to the outside. The upper bending part 41 passes through the first through hole 71 of the metal sheet, meanwhile, the metal sheet applies a pulling force to the inclined pressing rod towards the center direction, the joint of the lower bending part 43 and the straight rod part 42 is abutted against the upper surface of the end part of the transverse pressing rod 5, and the tail end of the lower bending part 43 extends to the lower part of the fixed end of the fixed hook 8.
Preferably, in this embodiment, the free end of the lower bent portion 43 is provided with a short top sheet 44 forming an acute angle with the lower bent portion, and the short top sheet 44 extends below the fixed end.
The fixed end of the fixed hook 8 is provided with a second through hole (not shown in the figure), the second through hole is internally provided with an adjusting screw 6, and the bottom of the adjusting screw 6 penetrates through the second through hole to abut against the short top plate 44.
In this embodiment, it is preferable that the stability of the entire head is improved, that the surfaces of both ends of the lateral pressing rod 5 are provided with grooves, and that the bottom ends of the lower bent portions abut against the grooves.
The pressure plate of the oblique pressure rod upwards supports against the adjusting screw 6 on the corresponding fixed hook, the lower bending part 43 of the oblique pressure rod 4 contacted with the fixed hook 8 downwards supports against the groove of the transverse pressure rod 5, so that the transverse pressure rod 5 generates a downward acting force, the transverse pressure rod 5 supports against the sealing seat, and the sealing seat 3 bears against the water outlet to play a role in sealing. After the nozzle is assembled, if the pressure generated by the transverse compression rod 5 to the seal seat 3 is small, and water leakage is possibly caused, the pressure of the adjusting screw 6 to the inclined compression rod 4 can be increased through the adjustment of the adjusting screw 6, the pressure to the transverse compression rod 5 can be increased through the inclined compression rod 4, and therefore the acting force to the seal seat 3 can be increased.
The metal sheet is made of a copper sheet, but other metal materials may be used.
Specifically, the fixing hook 8 is a C-shaped flat rod member, the transverse pressing rod 6 is a substantially straight flat rod member, and grooves are formed at two ends of the flat rod member. More specifically, the fixed end and the connecting end of the fixing hook 8 are parallel to each other, and the fixed end is shorter than the connecting end, so as to ensure that the oblique pressing rod is not affected by the splash box, in the horizontal direction, the fixed end and the splash box are kept at a certain distance, that is, the oblique pressing rod is ensured not to contact with the splash box when being inclined by the pulling force of the metal sheet.
The water splashing disc 2 is disc-shaped, and tooth grooves are uniformly formed in the surface of the water splashing disc along the circumferential direction.
In the present embodiment, the body 1, the seal holder 3, and the splash plate 2 are preferably coaxially provided.
The working principle of the invention is as follows:
when a fire disaster happens, the temperature sensing element arranged on the outermost side of the top of the spray head is heated under the action of radiant heat, when the temperature is raised to a certain temperature, the solder between the metal sheets is melted, the two metal sheets are separated, the upper parts of the 2 inclined pressing rods 4 are not restrained, the upper parts of the 2 inclined pressing rods 4 move towards the direction far away from each other, the lower parts of the inclined pressing rods 4 are separated from the adjusting screws 6, and the acting force of the inclined pressing rods 4 on the transverse pressing rods 5 disappears. Therefore, the pressure of the transverse compression rod 5 on the sealing seat 3 disappears, and finally, the sealing seat 3 is pushed open by water pressure to extinguish fire.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
