Description
Technical field
The utility model relates to a kind of fire-fighting equipment, specifically refers to the heat response in automatic water-spraying fire-extinguishing system sprinkling nozzle, and it to stretch splash box with two-stage.
Background technology
Heat response belongs to the one in automatic water-spraying fire-extinguishing system sprinkling nozzle, is widely used in furred ceiling finishing at present and pursues place attractive in appearance, as hotel, restaurant, market, high-grade office building, office building and place of public amusement etc.Automatic sprinkler system is sprayed in protected area the target realizing controlling fire uniformly mainly through the water that shower nozzle sprays by splash box; therefore ensure that the water distribution uniformity in protected area is very important, otherwise automatic sprinkler system just forfeiture effect possibly.In reality, due to fire-fighting construction and decoration construction inharmonious, add that workmen is ignorant of the operation principle of heat response, according to fire department inspection, the heat response finding that there is more than 90% is installed not in place, head body is too absorbed in furred ceiling (has goed deep into 2-3 centimetre than correct installation), shower nozzle action during fire, shower nozzle splash box can only part or under at all just cannot reaching furred ceiling, have impact on the distribution performance of shower nozzle greatly, even there is large-scale water distribution white space, cause fire spread to expand, lose the due effect of automatic sprinkler system.If re-start adjustment to sprinkler height, then need the short standpipe of water system end all to change, more difficult is because furred ceiling completes, and difficulty of construction is very large, and not only quantities is large, and can destroy the furred ceiling installed, and causes furred ceiling again to be done over again.
Summary of the invention
The utility model object designs a kind of heat response of the splash box that stretches with two-stage, solves splash box when common heat response is installed and easily blocked by furred ceiling, hinder effectively watering cloth water problem.
The utility model object is achieved through the following technical solutions:
The utility model is formed primarily of water inlet pipe mouth, yoke bar, temperature sensing glass ball, one-level expansion link, secondary expansion link and splash box body; Water inlet pipe mouth and yoke bar are that metal is one-body molded; Seal receptacle is lived on temperature sensing glass ball one crown, and cap nut is withstood in other end, is firmly fixed by temperature sensing glass ball by tightening screw cap, and current are then enclosed in water inlet pipe mouth by seal receptacle; One-level expansion link has two, is symmetrically distributed in yoke bar, one-level expansion link hollow, and two establishes upper limit device and lower retainer respectively, and one-level expansion link freely up and down can slide along the aperture offered on yoke bar; Secondary expansion link lower end is fixed with the riveting of splash box body or weld fixed connection, and stop is established in upper end, and secondary expansion link can be free to slide in one-level expansion link; Concealing shade outer cover is connected with water inlet pipe mouth by screw thread; Hidden inner cover is connected with concealing outer cover by screw thread, and by rotating the position of the hidden inner cover of adjustment; Deckboard adopts the mode of low-temperature alloy three place's spot welding to be connected with hidden inner cover.
Furtherly, the height of one-level expansion link is less than along the distance to edge under concealing outer cover under water inlet pipe mouth, and the resistance that one-level expansion link slides up and down along aperture on yoke bar is enough little, there will not be clamping stagnation.
Furtherly, the height of secondary expansion link is less than the internal height of one-level expansion link, and the resistance that secondary expansion link slides up and down in one-level expansion link is enough little, there will not be clamping stagnation.
Above-mentioned utility model effectively can solve the problem that heat response watering water distribution affects by furred ceiling, and structure is simple, dependable performance, economically feasible.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described further:
The utility model object is achieved through the following technical solutions: the stretch heat response of splash box of band two-stage is formed primarily of water inlet pipe mouth, yoke bar, temperature sensing glass ball, one-level expansion link, secondary expansion link and splash box body.Temperature sensing glass ball withstands seal receptacle, seal water inlet, one-level expansion link hollow, freely up and down can slide along the aperture on yoke bar, secondary expansion link lower end is connected with splash box body and can be free to slide in one-level expansion link, one-level expansion link, secondary expansion link are respectively equipped with stopping means, the telescopic extensions of restriction expansion link.During use, the stretch heat response of splash box of band two-stage is communicated with water supply line by water inlet end, and shower nozzle should be installed straight down, by adjusting the height of hidden inner cover, deckboard is flushed with furred ceiling.
As shown in Figure 1, the present embodiment is formed primarily of water inlet pipe mouth 1, yoke bar 2, temperature sensing glass ball 3, one-level expansion link 4, secondary expansion link 5 and splash box body 6; Water inlet pipe mouth 1 and yoke bar 2 are that metal is one-body molded; Seal receptacle 10 is lived on temperature sensing glass ball 3 one crown, and cap nut 9 is withstood in other end, is firmly fixed by temperature sensing glass ball 3 by tightening screw cap 9, and current are enclosed in water inlet pipe mouth by seal receptacle 10; One-level expansion link 4 has two, is symmetrically distributed in yoke bar 2, one-level expansion link 4 hollow, and two establishes upper limit device 12 and lower retainer 13 respectively, and one-level expansion link freely up and down can slide along the aperture offered on yoke bar; Secondary expansion link 5 lower end is fixed with splash box body 6 riveting or weld fixed connection, and stop 11 is established in upper end, and secondary expansion link 5 can be free to slide in one-level expansion link 4; Concealing shade outer cover 7 is connected with water inlet pipe mouth by screw thread; Hidden inner cover 8 is connected with concealing outer cover 7 by screw thread, and by rotating the position of the hidden inner cover of adjustment; Deckboard 14 adopts the mode of low-temperature alloy three place's spot welding to be connected with hidden inner cover 8.
In the present embodiment, the height of one-level expansion link 4 is less than the distance on water inlet pipe mouth 1 time edge to concealing outer cover 7 times edges, and the resistance that one-level expansion link 4 slides up and down along aperture on yoke bar is enough little, there will not be clamping stagnation.
In the present embodiment, the height of secondary expansion link 5 is less than the internal height of one-level expansion link 4, and the resistance that secondary expansion link 5 slides up and down in one-level expansion link 4 is enough little, there will not be clamping stagnation.
It should be noted that: under the prerequisite ensureing structural strength, the cross section of yoke bar 2 lower end and the size of cap nut 9 enough little, large discrete to avoid current to produce when flowing through yoke bar 2 and cap nut 9, ensure that current substantially can keep columnar shape before arrival splash box.
The utility model is creationary to be proposed band two-stage and to stretch the heat response of splash box, compared with common heat response, the splash box distance of stretch out and draw back of this shower nozzle has grown nearly one times, and during fire, deckboard comes off, temperature sensing glass ball is broken, and current flow out, under the effect of gravity and water impact, splash box drops, and can stretch out in furred ceiling completely, impregnablely carries out water distribution, can solve the practical difficulty in current heat response installation, see Fig. 2.
As shown in Figure 3, in a furred ceiling 15, become two-way or multichannel by water inlet pipe mouth difference, the device in the present embodiment is installed, indoor multiple spot nozzle layout of sprinkler can be realized, thus thoroughly eliminate fire-fighting dead angle area.
