Description
Technical field
The utility model relates to the fire-fighting equipment technical field, concrete relates to a kind of temperature-sensing element external sprinkler tip.
Background technology
At present, existing fire-fighting is made of the frame body that has the yoke arm, splash box, temperature-sensing element and black box etc. with sprinkler tip, and temperature-sensing element and black box place frame body to pass through in the ring that yoke arm and splash box constituted.After action under the effect of temperature-sensing element at thermal current, for guaranteeing the distribution performance of sprinkler tip, the fragment of temperature-sensing element and black box should be promoted to break away from fully with sprinkler tip by current.And in fact because water pressure fluctuations, the variation of chip size or the deviation of part processing all might cause the fragment of temperature-sensing element and black box can not in time break away from sprinkler tip, and the position of deposition is at random, has directly influenced the distribution performance of sprinkler tip.Destroyed when the distribution performance that sprinkler tip is predetermined, its fire extinguishing effect is also with weakened.
The utility model content
Technical problem to be solved in the utility model is to overcome the existing the problems referred to above of existing sprinkler tip, and a kind of temperature-sensing element external sprinkler tip is provided.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of temperature-sensing element external sprinkler tip, comprise a body that is connected with fire protection pipeline, the splash box that water is evenly sprayed, experience temperature-sensing element, the black box of ambient temperature, it is characterized in that, also comprise a plurality of connection bodies and splash box and splash box be supported on pillar on the body, be connected on the splash box bottom surface lever hook and in order to accept the support of temperature-sensing element, lever piece; Center at described splash box has the hole, and described black box comprises the seal disc and the fore-set that is connected with seal disc of seal body water channel, and described fore-set passes the described hole at described splash box center; Be rotary with a screw on the described lever piece, described screw withstands described fore-set, and described lever piece is overlapped on the described lever hook and is installed on the temperature-sensing element in the described support.
The position that described lever hook contacts with lever piece is provided with a crotch of upwards digging, and the position that described lever piece contacts with lever hook is provided with a downward crotch, and both cooperatively interact by crotch.
Described lever hook and support are the both sides that the center branch is located at described splash box with the axis of body.
Described support is a V-shaped rest, and two upper ends are connected with described splash box.
Described lever hook is connected with described splash box by described pillar with described support.
Adopt a kind of connection the in riveted joint, screw thread, the welding manner between described pillar and described body and splash box and described lever hook and the described support.
The upper surface of described splash box is provided with one to hold the groove of black box.
Temperature-sensing element external sprinkler tip of the present utility model is a kind of temperature-sensitive releasing device, sprinkler tip under the servo condition is installed on the shower, the pretightning force of screw is delivered on the black box by temperature-sensing element, by the water channel in the black box cut-out body, flowing of block water, splash box is used for disperseing the current that flow out from body, and water is sprayed in the guard plot by predetermined distribution mode.
Generally speaking, when the guard plot breaking out of fire, the liquid in the temperature-sensing element moves under the effect of thermal current, discharge black box, press water promotes the black box motion and flows out, and current disperse and change to flow to after impacting splash box, in the guard plot, spray in the intended manner, implement fire extinguishing.
In order to guarantee the distribution performance of sprinkler tip, after the temperature-sensing element action, its fragment and black box should not change the distribution performance that sprinkler tip designs in advance.The utility model outside the zone of the ring that is constituted between splash box and the body, has been avoided temperature-sensing element design fully the temperature-sensing element fragment may be deposited on this zone and has been influenced the phenomenon of the distribution performance of sprinkler tip; Be provided with the groove that is used for to hold black box at splash box, after the temperature-sensing element action, black box does not come off, but move along the direction of design in advance, under the effect of current, be close in the groove of splash box, kept the uniformity of sprinkler tip distribution performance, avoided temperature-sensing element fragment and black box the deposition of randomness to occur fully and influence the possibility of distribution performance, improve the reliability of sprinkler tip distribution performance, strengthened the fire extinguishing effectiveness of sprinkler tip.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of a kind of temperature-sensing element external of the utility model sprinkler tip;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the schematic diagram after the temperature-sensing element action.
Among the figure: 1 is body, and 2 is black box, and 21 is seal disc, and 22 is fore-set, and 3 is pillar, and 4 is splash box, 41 is the hole, and 42 is groove, and 5 is screw, and 61 is lever hook, and 611 is crotch, and 62 is lever piece, 621 is crotch, and 622 is aperture, and 7 is support, and 8 is temperature-sensing element
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3, body 1 is a tubular joint, be provided with the step 11 of an installation black box 2 in the mouth of pipe of bottom, the mouth of pipe of bottom is outside equipped with three riveted holes, the two ends of three pillars 3 are the necking down structure, the necking down of upper end be inserted in the riveted holes on the body 1 and with body 1 riveted joint.Can certainly be outside equipped with two screwed holes at the mouth of pipe of bottom, and offer external screw thread, the necking down of the upper end of three pillars 3 is threaded with body 1 at the necking down position of upper end.The upper end of three pillars 3 directly can also be welded to connect with body 1 and other mode in the cards is connected.
