Abstract
The utility model relates to a kind of spanner one-way breather valves for aqualung, including valve inner core, suction joint, air outlet adapter, one end of valve inner core is coaxially installed with an inspiration valve seat by suction joint, the other end is coaxially installed with a gas discharge valve base by air outlet adapter, valve disc is mounted in inspiration valve seat and gas discharge valve base, one membrane is installed on valve disc, interior coaxial support respectively is equipped with two layers of check ring on the valve inner core on the inside of suction joint and air outlet adapter.Spanner one-way breather valve provided by the utility model for aqualung can make breathing gas one-way flow, and reduce respiration dead space, avoid carbon dioxide poisoning.Meet simultaneously it is underwater open, close breather valve and do not intake requirements, this one-way breather valve is without using O-ring, it is no longer necessary to regularly replace O-ring, reduce the maintenance work of respirator, reduce use cost.
Description
Technical field
The utility model belongs to diving apparatus field, especially a kind of spanner one-way breather valve for aqualung.
Background technique
Aqualung is the equipment for guaranteeing diver and breathing safely under water.In order to guarantee that diver uses Breathing device for
Fresh gas can be smoked when device, the turbidity thereof of exhalation will not be sucked again by diver, design this kind of Breathing device for
It when the breath cycle pipeline of device, needs that check valve is arranged on pipeline, preventing the gas of exhalation from repeating sucking by diver causes
Carbon dioxide poisoning.Existing one-way breather valve uses O-ring structure, but due to O-ring rubber material to seal
Service life limitation, needs to regularly replace O-ring to guarantee the sealing of one-way breather valve.Which increase the maintenance costs of aqualung
And difficulty.
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 spanner one-way breather valve for aqualung.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of spanner one-way breather valve for aqualung, including valve inner core, suction joint, air outlet adapter, in valve
One end of core is coaxially installed with an inspiration valve seat by suction joint, and the other end is coaxially installed with an air outlet valve by air outlet adapter
It is mounted on valve disc in seat, inspiration valve seat and gas discharge valve base, a membrane is installed on valve disc, in suction joint and outlet
Coaxial support is equipped with two layers of check ring respectively on valve inner core on the inside of connector.
Moreover, being equipped with a valve chest in the valve inner core, connect in the middle part of the breathing interface tube in the middle part of valve chest and valve inner core
It is logical, spanner is installed on the valve chest corresponding to the axisymmetric position of valve chest breathing interface tube.
The advantages and positive effects of the utility model are as follows:
Spanner one-way breather valve provided by the utility model for aqualung can make breathing gas one-way flow,
And respiration dead space is reduced, carbon dioxide poisoning is avoided.Meet simultaneously it is underwater open, close breather valve and do not intake requirements, originally
One-way breather valve does not use O-ring, it is no longer necessary to regularly replace O-ring, reduce the maintenance work of respirator, reduce use
Cost.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure (axis section view) of the utility model.
In figure, 1. membranes, 2. valve discs, 3. suction joints, 4. valve inner cores, 5. valve chests, 6. air outlet adapters, 7. springs
Retaining ring, 8. spanners.
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 spanner one-way breather valve for aqualung, including valve inner core 4, suction joint 3, air outlet adapter 6, valve
One end of inner core is coaxially installed with an inspiration valve seat by suction joint, and the other end is coaxially installed with an outlet by air outlet adapter
Valve seat is mounted on valve disc 2 in inspiration valve seat and gas discharge valve base, a membrane 1 is installed on valve disc, in suction joint and
Coaxial support is equipped with two layers of check ring 7 respectively on valve inner core on the inside of air outlet adapter.
Valve inner core is expanded with four check rings, the inner wall of the outer wall and valve chest that make valve inner core reaches sealing state
Tight fit degree.
One valve chest 5 is installed in valve inner core, is connected in the middle part of the breathing interface tube in the middle part of valve chest and valve inner core, in valve casing
Spanner 8 is installed on valve chest corresponding to the axisymmetric position of body breathing interface tube.
When air-breathing, the diaphragm on the right is opened, and the diaphragm on the left side is closed, and fresh gas enters in valve to be inhaled by diver again
With；When expiration, the diaphragm on the left side is opened, and the diaphragm on the right is closed, and muddy gas is spat as in valve by diver, then arranged from the left side
Out.
When diver needs one-way breather valve to push spanner, rotation on the other hand from connector when taking in the mouth, is caught on the other hand at this time
Turn about 45 degree, one-way breather valve can be closed.When opening, first passes through bite and blow outward, then reverse push wrench.
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.
