Description of the drawings
Fig. 1 is a kind of structural schematic diagram of one embodiment of device for lowering persons charge valve provided by the utility model.
Fig. 2 is the enlarged drawing in the portions A in Fig. 1.
Fig. 3 is the enlarged drawing in the portions B in Fig. 1.
Specific implementation mode
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 charge valve provided by the utility model includes valve body 1, is connected to valve body
The connector 2 of one end, be arranged the valve body other end air inlet 11, valve disc 3 in body cavity, and removable connection are set
In the spool 4 for closing air inlet of valve disc.Wherein, spool 4 includes the valve rod 41 being connect with valve disc 3, for closing air inlet
The closing disk 42 of mouth 11.It is additionally provided with a spring 5 between spool 4 and valve disc 3, in the present embodiment, spring is cylindrical spring, specifically
It is sheathed on valve rod 41, while the both ends of spring contact valve disc 3 and closing disk 42 respectively.It is provided with one between spool 4 and air inlet 11
For the washer 6 of closed valve body, the present embodiment middle washer is silicone gasket.
Connector 2 includes the first connector 21 for connecting valve body 1 and the second connector 22 for connecting tracheae, is connected
It is to be threadedly coupled between the first connector 21 and valve body 1 of connector 2.One to be provided between 1 inner wall of connector 2 and valve body close simultaneously
Seal 7, sealing ring 7 are specifically located between 1 inner wall of the first connector 21 and valve body.In the peripheral side of the second connector 22, also
Multiple lug bosses 23 are provided with, for the second connector for connecting tracheae, lug boss can make the company between the second connector and tracheae
It connects even closer.
Valve disc 3 includes central part, and the multiple ribs for connecting 1 inner wall of central part and valve body extended from central part
Portion is provided with the interconnecting piece for connecting spring in the side of valve disc 3 towards air inlet, a through-hole is equipped at 3 central part of valve disc,
The valve rod 41 of spool 4 is removable to be connected to through hole.In the present embodiment, flank is provided with 3, and the angle of adjacent flank is
120°。
When specific works, gas enters from air inlet 11, and when admission pressure is more than 1.8kPa, spring 5 is compressed, spool
