Abstract
The invention relates to the technical field of fire fighting instrument, in particular to a novel spray head sealing module. The novel spray head sealing module comprises a sealing pad and a ball seat, wherein a groove is formed in the middle of the sealing pad and outwards extends in a bell-mouthed mode and is inwards bent to form a detoured portion, and the detoured portion is an annularly-arranged sheet. The ball seat extends along the sealing pad and is exposed out of the detoured portion. The groove is formed in one end where a fire extinguishing agent is arranged, the fire extinguishing agent is located at the detoured portion, pressure opposite to the flowing direction when the fire extinguishing agent works is formed and enables the detoured portion (namely the annularly-arranged sheet) to be tightly pressed on an internal channel of a spray head, the sealing effect of the sealing pad is also very good even under the effect of small assembly force, large supporting force for the sealing pad, of a temperature sensing element, is not needed, the hardness requirement for the temperature sensing element is reduced, and the selecting range of the temperature sensing element is widened.
Description
Technical field
The present invention relates to fire-fighting equipment technical field, particularly relate to a kind of new type nozzle black box.
Background technology
At present, the autoamtic fire extinguishing jet head that fire-fighting uses has two kinds, and one seals nozzle with low-melting alloy, and when alloy melting, extinguishing chemical sprays automatically; Another kind seals nozzle with the glass envelope that liquid is housed, and when the temperature increases, in glass envelope, liquid gasification expands, and glass envelope is burst, and extinguishing chemical automatically sprays and realizes fire extinguishing; Above-mentioned two kinds of modes all adopt sealing gasket to seal nozzle.
Notification number is that the Chinese utility model patent of CN 2263553Y discloses a kind of autoamtic fire extinguishing jet head, is made up of valve body and driver part, described driver part by sealing gasket, memory alloy element and jackscrew three parts form; Described valve body has the fork configuration of bayonet socket in being, described sealing gasket is positioned on the bayonet socket of described valve body; Described memorial alloy is arranged in described valve body, its two ends respectively by described sealing gasket and described jackscrew spacing; State institute's sealing gasket and comprise copper bearing, described copper bearing and described interchannel are provided with sealing rubber ring.
Sealing gasket in above-mentioned autoamtic fire extinguishing jet head, described copper bearing stops that the water in pipeline flows to shower nozzle direction, be provided with sealing rubber ring at described copper bearing and described interchannel simultaneously, increase described copper bearing and described interchannel sealing, current can not be flowed out by described copper bearing and described interchannel gap.But, because needs reduce described copper bearing and described interchannel gap, described memory alloy element is needed to have larger support force to described copper bearing, high to the hardness requirement of memorial alloy, described memorial alloy also needs to meet lower fusing point simultaneously, and the material of described like this memorial alloy selects requirement very high; Meanwhile, long-time use after, described rubber ring easily and shower nozzle inner passage and described bearing bond, affect the sensitivity that shower nozzle controls automatically.
Summary of the invention
The object of the invention is to: the problems referred to above existed for prior art, provide a kind of sealing gasket low to fusible link hardness requirement, the present invention also aims to provide a kind of and be not easy to described shower nozzle inner passage and glue glutinous sealing gasket.
To achieve these goals, the technical solution used in the present invention is:
A kind of new type nozzle black box, comprises sealing gasket and ball seat, and be provided with groove in the middle of described sealing gasket, described groove stretches out with bell-mouthed form, and the formation rebate that bends inwards, described rebate is circular thin slice; Described ball seat extends along described sealing gasket, and exposes described rebate.That is, except not having described rebate, the shape of described ball seat is identical with the shape of described sealing gasket.
Black box of the present invention, during injector seals, install temperature-sensitive support component in the groove of described ball seat, described ball seat and described sealing gasket are fixed on the installation position of shower nozzle inner passage, described ball seat is positioned at the front end of described sealing gasket; Described ball seat covers described sealing gasket and is fixed in described installation position, and described rebate (i.e. described annular wafer) and shower nozzle inner passage recline and become a part for shower nozzle inner passage.When shower nozzle inner passage is filled with extinguishing chemical, extinguishing chemical fills at described sealing gasket inner, and namely extinguishing chemical fills the concave part formed at described horn mouth and described rebate.Extinguishing chemical is at described rebate place, form the pressure that when working with described extinguishing chemical, flow direction is contrary, described rebate (i.e. annular thin slice) is tightly pressed on described shower nozzle inner passage by this pressure, even if under less assembly force effect, the sealing effectiveness of sealing gasket also can be fine, do not need temperature-sensing element to have larger support force to it, reduce the requirement to temperature-sensing element hardness, expand the range of choice of temperature-sensing element.
As preferred version of the present invention, described rebate and described bell-mouthed connecting portion curved.Described rebate and described bell-mouthed connecting portion is curved seamlessly transits, during sealing gasket work, connecting portion everywhere stress distribution is even, and sealing gasket is not easily damaged.
As preferred version of the present invention, described black box is teflon seal assembly.Injector seals assembly of the present invention, polytetrafluoroethylene (PTFE) ball seat is compared to metal ball seat of the prior art, not easily corrode, and cost of manufacture is low; Utilize polytetrafluoroethylene (PTFE) to obtain described sealing gasket, long-time use also can not bond with shower nozzle, and after temperature-sensitive support component destroys, sealing gasket and ball seat are departed from by sealing station, and the shower nozzle response time is rapid, and sealing gasket is long for service time.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, injector seals assembly of the present invention, be provided with groove in the middle of described sealing gasket, described groove stretches out with bell-mouthed form, and the formation rebate that bends inwards, described rebate is annular wafer; When shower nozzle inner passage is filled with extinguishing chemical, extinguishing chemical fills the concave part formed at described horn mouth and described rebate, and at described rebate place, form the pressure that when working with described extinguishing chemical, flow direction is contrary, described rebate (i.e. annular flake) is only pressed on described shower nozzle inner passage by this pressure, just fine at the sealing effectiveness of less assembly force effect lower seal pad, temperature-sensing element is not needed to have larger support force to it, reduce the requirement to temperature-sensing element hardness, expand the range of choice of temperature-sensing element.
2, compared to black box of the prior art, i.e. metal ball seat, is provided with rubber seal between metal ball seat and sprayer channel, and teflon seal assembly of the present invention, not easily corrode, and cost of manufacture is low; Utilize polytetrafluoroethylene (PTFE) to obtain described sealing gasket, long-time use also can not bond with shower nozzle, and after temperature-sensing element destroys, sealing gasket and ball seat are departed from by sealing station, and the shower nozzle response time is rapid; Teflon seal assembly of the present invention can use for a long time simultaneously.
