Description
Technical field
The utility model relates to a kind of gas feeder, is meant a kind of tidal air box with balance post rod structure especially.
Background technology
Along with the constantly variation of people's work, life style, heavy duty service, diving, rescue under water etc. become the known industry of people gradually, and these industries are because be in the environment of anoxic or anaerobic, so have certain danger.In order to ensure staff's safety and guarantee normally finishing of above-mentioned work, people produce a kind of diving breathing apparatus, use during in work or escape to supply with the staff under anoxic even the oxygen-free environment.Diving breathing apparatus is a kind of air self-carrying open loop single tube type gas feeder of being difficult to articulate, and has obtained being extensive use of of people as the attendant equipment tidal air box of diving breathing apparatus.
What traditional tidal air box used has two kinds more widely, first kind of tidal air box for no adjustment mechanism; And second kind for having the tidal air box of adjustable and balancing mechanism.More than the structure of two kinds of traditional tidal air boxes be described below.
Its keystone configuration comprises that air cavity, valve, breather cheek valve door and air cavity in-to-in eardrum are connected with a ripping bar between the stem of valve of this eardrum and breather cheek valve for the tidal air box of no adjustment mechanism; And its keystone configuration is to have increased a pin-lift arrangement and set screw for the breather cheek valve door on the basis of the tidal air box of no adjustment mechanism for the tidal air box with adjustable and balancing mechanism, and this push rod holds between stem of valve and set screw.When the user states two kinds of tidal air boxes in the use, the user only need hold in the mouth and bite valve, air-breathing by valve, make the inner negative pressure that produces of this air cavity, this eardrum is agitated under the effect of negative pressure, levers up valve inside thereby drive ripping bar, air intake valve is opened, air is input in the air cavity by air intake valve, supplies with the user by valve again, so repeatedly to reach the purpose of air feed.
But aforesaid traditional tidal air box still exists some shortcomings and is described below now in the process of using.
When the user uses above-mentioned first kind of tidal air box, it is reciprocating to utilize the negative pressure that produces when air-breathing to drive eardrum, the motion of eardrum drives ripping bar and levers up stem of valve, thereby open air intake valve, but because the sense of motion of eardrum and stem of valve is inconsistent, can be when so ripping bar prizes valve inside under the drive of eardrum to the subsidiary certain horizontal force of stem of valve, make the stem of valve of breather cheek valve in the process that axially moves, be subjected to certain resistance, and these resistances can to a certain degree hamper the smooth unlatching of breather cheek valve, make the normal conveying of oxygen be subjected to negative effect, under oxygen-free environment, use the staff or the escape personnel of this tidal air box to cause huge psychological pressure thereby give, thereby bring unnecessary fear.
Second kind of traditional tidal air box is because structurally had more a push rod and regulated set screw than first kind of tidal air box.The user is when implementing second kind of tidal air box, this push rod can play the effect of a guiding, the door bar of guiding air inlet valve axially moves when skidding off the valve circle, can be because of from a part of horizontal force of ripping bar and be affected, set screw turns the stroke size of controlling stem of valve, thereby reach the purpose of regulating the air intake valve aperture, but this set screw often has only the proper operation of professional person's ability, with this tidal air box during as a kind of escaping tool, set screw belongs to a kind of unnecessary structure concerning the personnel of escape, this set screw be arranged on the productive costs that improves this tidal air box the time but can't play corresponding effect, even can should be user's maloperation and produce negative influences such as cutting off oxygen supply.
