Abstract
The utility model discloses a positive-pressure type firefighting air respirator. The firefighting air respirator comprises an oxygen supply bottle, a pressure reducing valve, an oxygen conveying pipe, an oxygen receiving pipe and a hood which are sequentially connected with one another, wherein the oxygen receiving pipe is communicated with the hood through a supply valve. As the supply valve is additionally arranged, the oxygen receiving pipe is communicated with the hood 7 through the supply valve; in this case, a user can adjust the opening-closing degree of the supply valve according to the oxygen needing quantity to obtain proper oxygen supply quantity, thereby preventing the choking condition caused by excess oxygen supply quantity; therefore, the user can smoothly respire oxygen. The positive-pressure type firefighting air respirator is convenient to use, has a simple structure and is quite popular with the vast users.
Description
Technical field
The utility model relates to a kind of fire-fighting relief respirator field; be specifically a kind of fireman of being applicable to or rescue personnel at poisonous or pernicious gas environment, contain in the environment such as harmful substances such as flue dust and anoxic and use, the positive-pressure type fire-fighting air respirator of effective respiratory protection is provided for the user.
Background technology
At present, in fire-fighting relief, particularly at poisonous or pernicious gas environment, contain in the environment such as harmful substance such as flue dust and anoxic, all be to use respirator basically, wherein, it is comparatively in the majority that the positive-pressure type fire-fighting air respirator uses.Common positive-pressure type fire-fighting air respirator, its structure generally comprise oxygen supply bottle, pressure-reducing valve, oxygen cathete, oxygen-connecting tube and the head-shield that connects in turn.The respirator of this structure, owing to be that the oxygen of oxygen supply bottle directly is delivered to head-shield by pressure-reducing valve, directly be supplied to the user, the oxygen that transports out from pressure-reducing valve, generally comparatively a large amount of, for different users, each user's oxygen demand is different, for this reason, so direct keeping, under a lot of situations is what supply exceed demand, causes user's gas phenomenon that occurs choking, and all makes the user sweet to uncomfortable under a lot of situations.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of gas that effectively prevents to choke, positive-pressure type fire-fighting air respirator easy to use, simple in structure are provided.
Goal of the invention of the present utility model is achieved in that a kind of positive-pressure type fire-fighting air respirator, and it comprises oxygen supply bottle, pressure-reducing valve, oxygen cathete, oxygen-connecting tube and the head-shield that connects in turn, it is characterized in that: described oxygen-connecting tube is communicated with head-shield by a supply valve.
Described supply valve is located at the bottom of head-shield.
Described oxygen cathete is communicated with oxygen-connecting tube by a snap joint.
Described oxygen-connecting tube is middle pressure flexible conduit.
Described positive-pressure type fire-fighting air respirator is provided with the back bracket that is used to bear the oxygen supply bottle.
The bottle mouth position of described oxygen supply bottle is provided with the self-locking bottle valve.
Described oxygen supply bottle is provided with the pressure monitoring and alarm device that is communicated with bottleneck.
Described pressure monitoring and alarm device comprises bleed pressure table and overbottom pressure siren alarm.
The utility model is compared with the positive-pressure type fire-fighting air respirator of routine, and it has the following advantages:
The utility model is on the sequently connected oxygen therapy passage by oxygen supply bottle, pressure-reducing valve, oxygen cathete, oxygen-connecting tube and head-shield, set up a supply valve, described oxygen-connecting tube is communicated with head-shield by a supply valve, and the user can regulate the folding degree of supply valve according to the oxygen demand of self, to obtain suitable oxygen-supplying amount, prevent the gas phenomenon of choking that occurs because of oxygen supply is excessive, can make the user be subjected to oxygen freely suitable, with this product that constitutes, it is easy to use, simple in structure, be subjected to user's favor deeply.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1; the described positive-pressure type fire-fighting air respirator of present embodiment; it be applicable to fireman or rescue personnel at poisonous or pernicious gas environment, contain in the environment such as harmful substances such as flue dust and anoxic and use; for the user provides effective respiratory protection, be widely used in departments such as fire-fighting, electric power, chemical industry, boats and ships, smelting, warehouse, laboratory, mine.Its structure comprises in turn oxygen supply bottle 8, pressure-reducing valve 10, oxygen cathete 5, oxygen-connecting tube 3 and the head-shield 7 that connects, and head-shield 7 is the full head-shield 7 in the big visual field, antifog, anti-dazzle, broad view, good, the comfortable wearing of air-tightness.And pressure-reducing valve 10 volume compact, built-in safety valve, dependable performance does not have any adjusting device, and is non-maintaining.Be provided with spare interface, can install him as required additional and rescue joint or outer air supply source.Described oxygen-connecting tube 3 is communicated with head-shield 7 by a supply valve, and described supply valve is located at the bottom of head-shield 7.
During this time, in the preparation of product process, described oxygen cathete 5 is communicated with oxygen-connecting tube 3 by a snap joint 4, and described oxygen-connecting tube 3 is middle pressure flexible conduit; Described positive-pressure type fire-fighting air respirator is provided with the back bracket 7 that is used to bear oxygen supply bottle 8, and the user can this product of toter, freedom and flexibility, this back bracket 7 is generally made by carbon fibre composite, in light weight, intensity is high, ergonomically the design, wear more comfortable, more convenient.The bottle mouth position of described oxygen supply bottle 8 is provided with self-locking bottle valve 9, can prevent that oxygen supply bottle 8 from use being closed unintentionally, at this moment, the cylinder valve that also can elect additional member band pressure to show, also can display bottle when valve closing in air storage pressure.Described oxygen supply bottle 8 is provided with the pressure monitoring and alarm device 5 that is communicated with bottleneck, described pressure monitoring and alarm device 5 comprises bleed pressure table and overbottom pressure siren alarm, the bleed pressure table has waterproof, shockproof, noctilucence Presentation Function, and overbottom pressure siren alarm volume is little, in light weight, it is accurately loud and clear to report to the police.
The utility model is by setting up a supply valve, described oxygen-connecting tube 3 is communicated with head-shield 7 by a supply valve, the user can regulate the folding degree of supply valve according to the oxygen demand of self, to obtain suitable oxygen-supplying amount, prevent the gas phenomenon of choking that occurs because of oxygen supply is excessive, can make the user be subjected to oxygen freely suitable, with this product that constitutes, it is easy to use, and is simple in structure, is subjected to user's favor deeply.
