Abstract
The utility model relates to a flame spreading device for a fine dry powder fire extinguisher, which comprises a body with a flame spreading opening, wherein an external thermosensitive line is arranged in a sleeve and is connected with the body through interfaces at the two ends of the body, and outer screw threads are arranged on the interfaces of the body; the upper end of the outer screw threads is in a tapered shape, and the whole sleeve is in a straight cylindrical shape; one end of the sleeve is in a tapered shape and corresponds to the interface of the body, and a nut is sleeved on the sleeve; and the nut corresponds to the outer screw threads on the body. The utility model improves the connecting mode of the thermosensitive line and the flame spreading body, the tapered contact surface is designed based on the connection of the screw threads and the nut so as to ensure the contact sealing, thereby greatly increasing the stability and reliability of the device; and the utility model has the characteristics of simple structure, convenient installation and maintenance, low manufacturing cost and the like.
Description
Technical field
The utility model relates to the fiery assembly of a kind of biography, especially a kind of biography fire device that is used for the ultra-fine dry powder fire extinguisher.
Background technology
The ultra-fine dry powder fire extinguisher is widely used in the office space, vehicle, residence etc., its basic structure and extinguish material have unified national standard, wherein pass the use that directly has influence on this device of fiery assembly, generally adopt the biography fire device of plug-in type structure in the market, this device interlude links to each other with initiator, two ends link to each other with heat-sensitive line respectively, heat-sensitive line is with sleeve pipe outward, pass fiery body two connectivity ports and adopt the structure that patches of elastomeric element, this sleeve pipe links to each other with the fiery body of biography by the plug-in type structure, and it is not firm contact often to occur in the practical application of above-mentioned biography fire device, problems such as replaceability difference, and this kind apparatus structure more complicated, the manufacturing cost height.
Summary of the invention
The purpose of this utility model is a kind of simple in structure, fiery device of the simple biography of maintenance that is used for the ultra-fine dry powder fire extinguisher of design, and the technical solution of the utility model is so to realize:
A kind of biography fire device that is used for the ultra-fine dry powder fire extinguisher, comprise that band passes the body of burner, external heat-sensitive line is located in the sleeve pipe, and links to each other with body by the interface at body two ends, and the interface (4) on the body (10) is provided with external screw thread (6), external screw thread (6) upper end is tapered, sleeve pipe (5) is the whole straight-tube shape that is, an end is tapered, and is corresponding with interface (4) on the body (10), be set with nut (2) on the sleeve pipe (5), nut (2) is corresponding with external screw thread (6) on the body (10).
As preferably, locates to be provided with a circle groove (7) near external screw thread (6) on the body (10).
As preferably, nut (2) shaped upper part is taper, be convenient to body (10) on interface (4) connect installation.
As preferably, sleeve pipe (5) is provided with the stamped groove (11) that is used for nut (2) location.
The utility model has improved heat-sensitive line and the connected mode that passes fiery body, on screw thread, nut connection basis, designed conical contact face, compared with prior art, have following characteristics: 1, sound construction compactness, interface on the body adopts screw thread to add the form of bell, forms correspondingly with the bell of sleeve pipe, guarantees the contact sealing, adopting shaped upper part again is that the nut of taper is tightened, and has increased the reliability of device greatly.2, the circle groove design near the external screw thread place can realize this device and positioning relations other parts during practical application, having reasonable effect on the body.The utility model is simple in structure, convenient for installation and maintenance, and low cost of manufacture is easily applied.
