Description
Technical field
The present invention relates to a kind of hydraulic spray nozzle that utilizes the extinguishing chemical medium to carry out fire-fighting by hard-wired pipe-line system; wherein the protection of scattering shower nozzle is in nozzle housing; shower nozzle comes out from nozzle housing when acting on the pressure-activated shower nozzle of extinguishing chemical medium, and shower nozzle automatically retracts to nozzle housing when the pressure that acts on the extinguishing chemical medium stops.
Background technology
Hydraulic spray nozzle is very general in fire extinguishing system, and wherein nozzle is arranged in the hard-wired pipe-line system usually.Known scattering nozzle is protected in case mechanical collision from the watering device with figure of confusion; wherein sprinkler head is installed in the wire cage usually; this wire cage provides mechanical protection for the figure of confusion of the rapid wear in the sprinkler head, and allows the figure of confusion to scatter the extinguishing chemical medium to the wire cage outside simultaneously.With during spraying system is connected, water mist droplets will roll up bigger drop on wire cage.
Being preferred for not having the another kind of method of protection of the nozzle of the figure of confusion is to protect shower nozzle by protective sleeve, and this protective sleeve leaves nozzle by the pressure that acts on the extinguishing chemical medium.Protective sleeve is provided with the wire that is fixed in nozzle or pipe-line system or chain etc. usually, so that protective sleeve can be installed on the nozzle once more quite simply after nozzle has been activated.
Through be usually used in installing on desk or other surfaces etc. nozzle and in ventilation shaft etc. the third method of installation nozzle will use such nozzle; wherein the top of shower nozzle is formed with cover plate; make described cover plate be engaged in flange or the groove in the surface, cover plate protection scattering nozzle is avoided mechanical collision when being not activated with convenient nozzle.When nozzle started, it highlighted from flange, scattered the extinguishing chemical medium by it.The shortcoming that has the surface at the shower nozzle end is that this surface obstruction nozzle scatters the extinguishing chemical medium equably at the axial direction of nozzle.
FR2754729 discloses a kind of device, and wherein nozzle is not protected fully to allow to use the necessary sensitiveness nozzle of generation mist, promptly so-called hydraulic spray nozzle.In addition, between the different parts of nozzle use location, there is not effective liquid sealing.
In addition, DE1798549 discloses a kind of nozzle that nozzle can be withdrawn into the spring assembly of its retracted position that has.But this device is insecure, because nozzle just can not be worked when spring fracture, thereby can not withdraw nozzle.
Summary of the invention
Novelty of the present invention is that shower nozzle is provided with spring-loaded pipe, and this pipe is arranged in the nozzle housing with two chambers.The elastic force of compression spring is less than the power that is transferred to pipe from the extinguishing chemical medium, thereby when the extinguishing chemical medium pressurizes, the extinguishing chemical medium will be from nozzle housing extruding jet forward, and when the extinguishing chemical medium was removed once more to the extruding of shower nozzle, spring promoted shower nozzle and returns nozzle housing.Therefore the present invention provides mechanical protection and allows to scatter without barrier the water smoke that has or do not have fire-proof additive simultaneously for shower nozzle, and need not use the protective sleeve that need install once more when nozzle uses.
Novelty of the present invention also is to be installed in the spring-loaded flap in the nozzle box; thereby shower nozzle can be arranged in the protective position of flap back in the nozzle housing; shower nozzle is appeared suddenly therefrom automatically when the extinguishing chemical medium pressurizes, and shower nozzle is withdrawn automatically when removing the extinguishing chemical pressure medium.Its novelty is that also spring-loaded pipe can be divided into several tube portions, and each part all is spring-loaded and can relative to each other moves.Therefore shower nozzle has a movable length of being longer than single pipe, can be used for removing the barrier of shower nozzle, if any, is used for the distribution of extinguishing chemical medium, and the while shower nozzle automatically turns back to the protective position of nozzle housing nozzle box.

The specific embodiment
The present invention is a kind of shower nozzle 1 with band reflector 2 or with the shower nozzle in the shower nozzle 3 of two or more splash box 4i, 4n and/or band central nozzle hole 5 or with the hydraulic spray nozzle (Fig. 1) of the shower nozzle of two or more nozzle bore 5i, 5n.It in the extending axially of shower nozzle pipe 6, it has sealing surfaces 7i, the 7n of conical sealing surfaces 7 or other structures, and the composition surface 8 of compression spring, with support slider disc 10 or have good release as the PTFE material and the stayed surface 9 of the thin film disk of the non-corrosive material of sliding properties, and the dish, nut or the locking surface 11 that slider disc 10 are remained in stayed surface 9.
This device is arranged in the nozzle housing 12 with connecting thread 13 or flange connector 14.Nozzle housing is provided with entrance point 15, filter 16 and spring housing 17, and this spring housing has the spring composition surface 19 that is shelved in the nozzle housing and the compression spring 18 on the spring composition surface 8 on the blast tube.And nozzle housing has the sealing surfaces of cone seal surface 20 or another kind of structure, with the through hole 21 that is connected spring housing and nozzle box 22.The nozzle box can open at the other end, and perhaps the nozzle box can close by flap 23, and described flap is usually by alignment pin 25 and optionally can be fixed on the hinge point 24 to the torsionspring 26 that flap 23 applies the power of closing.
The present invention operation makes compression spring 18 or compression spring 18i, 18n keep shower nozzle (1,3) to engage with the rear wall of nozzle box 22 in nozzle housing 12.
If the nozzle box is provided with flap 23, the biasing torsionspring 26 that so described flap is provided with by the hinge point 24 around flap keeps the flange engages with the nozzle box.When the extinguishing chemical medium was pressurized, the extinguishing chemical medium will be fixed to nozzle on the point of pipe-line system by the connecting thread 13 that pipe-line system flows to by them.
The extinguishing chemical medium will flow through filter 16 and enter entrance point 15, pressure from the extinguishing chemical medium will act on pipe 6 or pipe 6i, the 6n there, thereby spring 18 or compression spring 18i, 18n is compressed and nozzle occurs from nozzle box 22, therefrom the hole in the flowing pipe and be assigned to around around the shower nozzle through the extinguishing chemical medium of shower nozzle outflow unobstructedly.When closing the extinguishing chemical medium, medium stops to flow through system pipes to nozzle.The pressure of minimizing on the extinguishing chemical medium makes medium can flow out the nozzle of opening.Therefore, the pressure that acts on pipe 6 or the extinguishing chemical medium of 6i, 6n descends, thereby compression spring 18 or 18i, 18n are loosened, and shower nozzle turns back to nozzle box 22, wherein protects shower nozzle to avoid mechanical load.
Under the situation that the outlet of nozzle box 22 is closed by flap 23, when nozzle no longer kept flap to open, flap is close nozzle chamber automatically.
