Description of the drawings
Fig. 1 is a kind of structure diagram of one embodiment of device for lowering persons exhaust safety valve provided by the utility model.
Fig. 2 is the structure diagram of the present embodiment diaphragm.
Fig. 3 is the structure diagram of the present embodiment upper cover.
Specific embodiment
For ease of those skilled in the art understand that the utility model, below in conjunction with specific embodiments and the drawings to this practicality
It is novel to be described in further detail.
Referring to figs. 1 to Fig. 3, a kind of device for lowering persons provided by the utility model exhaust safety valve includes bottom flange 1, under
The matched bonnet, 2 of valve deck, the diaphragm 3 being arranged between bottom flange and bonnet, and both ends respectively with diaphragm and die holder
The spring 4 of connection.The intracavity diameter of bonnet, 2 is more than the outer diameter of bottom flange 1, and bonnet, can be fastened on bottom flange.In upper valve
The bottom of lid 2 is equipped with the first flange 23, is provided at bottom flange 1 and 23 opposite position of the first flange matched with the first flange
Second flange 13.Wherein, the side of diaphragm 3 towards bottom flange 1 is provided with the gasket 5 for connecting spring, and bottom flange 1 is provided with
For the connecting portion 11 of connecting spring.Rounded array is provided with the air admission hole 21 of multiple supplied gas circulations, lower valve at bonnet, 2
Lid 1 is provided with the venthole 12 of supplied gas outflow.The peripheral side of bonnet, 2 is additionally provided with screw thread 22, can be connected by the screw thread
The diving apparatuses such as tracheae or diving dress.
A through-hole 31 for gas to pass through is provided on diaphragm 3, is provided with to connect in the side of diaphragm towards bonnet, 2
The lug boss 32 of bonnet, inner wall is touched, the side of diaphragm towards spring 4 is additionally provided with the mounting portion 33 for installing gasket.This reality
It applies in example, diaphragm 3 is gel silica membrane, and spring 4 employs waveform spring, and gasket 5 is metal gasket.
During specific works, gas enters from air inlet 21 in valve body, and when pressure is more than 2.20kPa, diaphragm 3 is in gas
It is deformed upon under promotion towards 1 direction of bottom flange, spring 4 is compressed.The lug boss 32 of diaphragm 3 leaves the interior of bonnet, at this time
