Description
Technical field
The utility model belongs to diving apparatus field, especially a kind of reinforced gas supply for circulating aqualung
Valve.
Background technique
Circulating aqualung is that one kind can recycle breathing gas, extends the diving apparatus of diving time.For
Air valve belongs to important component in circulating aqualung, it can provide sufficient amount with gas demand according to diver
Gas.But steam supply valve currently on the market can only be supplied according to ambient pressure variations, in the quick dive of diver, Huo Zheqian
Gas in aquatic respiration device breathing bag is very little, and the automatic feeding amount of steam supply valve is unable to satisfy diver's demand, at this time diver
It can wait, this can make diver have the possibility of anoxic.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of structure it is simple, using safe
The reinforced steam supply valve for circulating aqualung.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of reinforced steam supply valve for circulating aqualung, including shell, valve deck, valve body and valve seat,
Case top is formed with opening, and lower part is formed with valve port, and valve deck is determined by locking nut in top, divides on the shell of valve port two sides
It is not provided with air entry and air inlet, is horizontally installed with a valve body in the shell between air entry and air inlet, valve body is coaxial
It is fixedly mounted with valve seat, valve seat and air inlet coaxially closed installation, is coaxially arranged with air intake duct in valve seat, the valve body of the air intake duct
Interior exit is coaxially closed by one end of a valve rod, and looping pit is provided in valve body, coaxial between the looping pit and valve rod
It is set with spring, a stop-nut is provided in the shell position on the inside of air entry, coaxially crimps valve in the retainer nut
The other end of bar, level is closed in the shell on valve body top is equipped with a diaphragm, and a lever is fixed with below the diaphragm
One end, the other end of lever are arranged close in the stem position of air entry side.
Moreover, groove is arranged in the stem position close to the air entry side, the bottom end of lever is inserted into the groove.
Moreover, closed in the middle part of the valve deck above the diaphragm be lifted with a mechanical button, the lifting part tool of the button
It is flexible and scalable.
The advantages and positive effects of the utility model are as follows:
Reinforced steam supply valve provided by the utility model for circulating aqualung not only can be according to environment pressure
Power variation automatically turns on, in extreme circumstances, such as the very fast dive of diver, but the air demand of steam supply valve is not met by diving
When member's demand, air demand can also be increased manually to meet the currently used demand of diver.
Detailed description of the invention
Fig. 1 is the structural schematic diagram (axis section view) of the utility model.
Appended drawing reference in figure be respectively as follows: 1. valve seats, 2. shells, 3. locking nuts, 4. diaphragms, 5. valve decks, 6. buttons,
7. retainer nut, 8. levers, 9. spring, 10. valve rod, 11. valve bodies.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of reinforced steam supply valve for circulating aqualung, including shell 2, valve deck 5, valve body 10 and valve
Seat 1, case top are formed with opening, and lower part is formed with valve port, and valve deck is determined by locking nut 3 in top, the shell in valve port two sides
It is respectively arranged with air entry and air inlet on body, is horizontally installed with a valve body, valve in the shell between air entry and air inlet
Body is coaxially fixedly mounted with valve seat, valve seat and air inlet coaxially closed installation, is coaxially arranged with air intake duct in valve seat, the air intake duct
The intracorporal exit of valve coaxially closed by one end of a valve rod 10, looping pit is provided in valve body, in the looping pit and valve rod
Between coaxial sleeve be equipped with spring 9, a stop-nut 7 is provided in the shell position on the inside of air entry, in the retainer nut
The other end of coaxial crimping valve rod, shell is interior to form a cavity by top cover and valve body, horizontal in the shell on valve body top
It is closed that a diaphragm 4 is installed, one end of a lever 8 is fixed with below the diaphragm, the other end of lever is arranged close to air-breathing
In the stem position of mouth side, specific mounting structure is that groove, lever is arranged in the stem position close to air entry side
Bottom end be inserted into the groove locking realized to valve rod, when diaphragm pushes, the junction of lever and diaphragm as fulcrum and
Lever swing is detached from groove, realizes the unlock to valve rod.
It is closed in the middle part of the valve deck above diaphragm to be lifted with a mechanical button 6, the lifting part of the button have elasticity and
It is scalable, such as rubber.
The working principle of the utility model is:
When diver's air-breathing causes to generate negative pressure in demand valve, diaphragm sink, and depresses lever, and then push valve open
Bar opens valve, and gas is flowed out from valve port at this time.When valve, which automatically opens degree, is insufficient for gas supply demand, press
Button forces diaphragm to sink, and depresses lever, expands valve openings degree, improves air demand with meet demand.When stop press by
Button, when valve internal and external pressure balance, diaphragm rebound, valve rod homing under the force of a spring closes valve, stops air inlet.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
