Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As Figure 1-Figure 2, described in the utility model is a kind of enclosed fire nozzle, it comprises nozzle body, this nozzle body is divided into shower nozzle construction section 1 and the section of being threaded 2, in shower nozzle construction section 1 and the section of being threaded 2, be respectively equipped with vertically the first water stream channel 101 and the second water stream channel 201 that communicate, in shower nozzle construction section 1, be provided with several shower nozzle installation portions 102 that are communicated with the first water stream channel 101 and be separately installed with little shower nozzle 3; The outer end of the first water stream channel 101 is provided with a glass tube support 4; In the first water stream channel 101 and the second water stream channel 201, be provided with a stepped piston rod 5, one end of described piston rod 5 is positioned at the second water stream channel 201 and conflicts with a Compress Spring 6 that is positioned at the second water stream channel 201, the other end of piston rod 5 extends in described glass tube support 4, and be arranged on glass tube 41 in glass tube support 4 to conflict; The outer end of the described section of being threaded 2 is also provided with an extension 21, these extension 21 external diameters are little compared with the external diameter of the section of being threaded 2, these extension 21 sidewalls offer the water inlet 211 that several and described the second water stream channel 201 is communicated with, and the outer screen pack 22 that is arranged with of extension 21, is also provided with screen pack adapter sleeve 23 and water blockoff head 24 in the outer end of this extension 21; Screen pack 22 is cylindric, and screen pack adapter sleeve 23, water blockoff head 24 are fixed with the mode that extension 21 is threaded connection.By screen pack adapter sleeve 23, water blockoff head 24, screen pack 22 is fixed on to the outside of extension water inlet, and block the outer end of extension 21, thereby the water entering in nozzle body is played a role in filtering, prevent the particles such as iron rust from entering nozzle body and cause the phenomenons such as little shower nozzle obstruction, avoiding fire nozzle Water-and mist-spraying poor effect even to lose efficacy.
On the corner of described extension 21 and the section of being threaded 2, the end face of the section of being threaded 2, offer an annular groove 212, one end of described screen pack 22 is limited in this annular groove 212.The one end that is screen pack 22 cylindraceous is plugged in this annular groove 212, and the other end is locked by screen pack adapter sleeve 23, makes screen pack 22 more firm.
The two ends of described piston rod 5 contact part and are separately installed with the first O-ring seal 71 and the second O-ring seal 72 with glass tube support 4 inwalls with the second water stream channel 201 inwalls; Between the first water stream channel 101 inwalls of described glass tube support 4 outer walls and shower nozzle construction section 1, be provided with the 3rd O-ring seal 73, so that each contact-making surface reaches sealing effectiveness.
With the corner of shower nozzle construction section 1, the 4th O-ring seal 74, the four O-ring seals 74 being installed in the described section of being threaded 2 is after nozzle is threaded with water pipe head, plays sealing function.
Uniform 5～7 shower nozzle installation portions 102 in described shower nozzle construction section 1, and the axis of shower nozzle installation portion 102 is skewed with respect to nozzle body axis.
Described little shower nozzle 3 comprises little nozzle body 31 and the eddy flow core body 32 setting within it, and little nozzle body 31 is threaded connection mode with shower nozzle installation portion 102 and is connected, and its periphery is also provided with the 5th O-ring seal 75.Little shower nozzle 3 is installed threadably, and assembly and disassembly are all very convenient, are also convenient for changing; The interior eddy flow core body 32 that arranges of little shower nozzle 3 can make current produce eddy flow, thereby make jeting effect better, under condition of high voltage, more easily form the water smoke that average grain diameter is less than 100 microns, specific area and distribution density are higher, reach better vaporization cooling and the oxygen barrier effect of suffocating.
Operation principle of the present utility model is: in the time of normal condition, piston rod 5 is static under the balanced action of its two ends glass tube 41 and Compress Spring 6, now piston rod 5 has stopped up the second water stream channel 201 and the first water stream channel 101, even if therefore, in the situation of nozzle body and cross current, also can not spray water.In the time there is the emergencies such as the condition of a fire, glass tube 41 is interior due to mercury being housed, in the time that its heating temperature reaches 68 DEG C, the automatic explosion of glass tube 41 meeting, now, glass tube 41 disappears to the conflict effect of piston rod 5, piston rod 5 in the effect of Compress Spring 6 and water flow pressure to 4 lateral movements of glass tube support, depart from the second water stream channel 201, the second water stream channel 201 and the first water stream channel 101 are connected, current flow to each little shower nozzle 3 through the first water stream channel 101, the spouting cooling fire extinguishing effect that reaches.
Again in conjunction with shown in Fig. 3～Fig. 6, in the utility model, little shower nozzle 3 can be selected the R little shower nozzle of series (shown in Fig. 2) or the M little shower nozzle of series (shown in Fig. 3) or the B little shower nozzle of series (shown in Fig. 4) or the S little shower nozzle of series (shown in Fig. 5) or the L little shower nozzle of series (shown in Fig. 6) according to the shape difference of its little nozzle body 31.
The utility model arranges screen pack 22 by water inlet 211 places at nozzle body, filters out into particles such as the iron rust in water, can prevent that nozzle body is inner and little shower nozzle 3 is blocked.The utility model nozzle has multiple little shower nozzles 3, can multi-direction water spray, and it is easy to install, jeting effect is better, under condition of high voltage, more easily form the water smoke that average grain diameter is less than 100 microns, specific area and distribution density are higher, reach better vaporization cooling and the oxygen barrier effect of suffocating, can be widely used in fire extinguishing, press down fire, control fire, temperature control etc., be highly suitable for the places such as Archive, steamer machine room, computer floor be inflammable and explosive.
