Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
As shown in Figs. 1-2, a kind of vehicle fresh air distributing valve of the invention, the driving that can be mounted on for a long time except closed shelter
Cabin, equipment compartment etc. fix position, the shell 1 and multiple valves 2 sealed including one.Wherein, shell 1 include for gas supply into
Air port 102 and multiple air outlets 103 for supplying gas, valve 2 connect one to one with air outlet 103 respectively, air inlet 102,
Air outlet 103 and valve 2 form one into the valve group having more, and reach more people practical purpose simultaneously.
In the present embodiment, there are an air inlet 102 and two air outlets 103 on shell 1, have at each air outlet 103
One valve 2, the entire valve group for forming one-in-and-two-out, air inlet 102 can access the clean air or oxygen in protection shelter,
Air outlet 103 is coupled with personal protection safety eyewear.Due to not needing to place oxygen cylinder in cockpit, equipment compartment,
It is suitable for vibration environment complicated on vehicle, safety is preferable.
As shown in Fig. 2, valve 2 may include valve body 104 and cylindrical spool 201, spool 201 passes through valve core case 203
It is rotatably inserted in valve body 104, valve core case 203 is fixed on valve body 104 by fixture nut 202, the side wall of valve body 104
On symmetrically set there are two the first ventilation opening, alternately symmetrically set that there are two the on the side wall of spool 201 with the first ventilation opening
Two ventilation openings, spool 201 can rotate in valve body 104, and when rotation, the state between the first ventilation opening and the second ventilation opening can
To become interlocking from coincidence, or from staggeredly becoming being overlapped, the first ventilation opening is overlapped situation control valve 2 with the second ventilation opening
Opening and closing, when the first ventilation opening is overlapped with the second ventilation opening, valve 2 open, 103 connection of air inlet 102 and air outlet, use
Person can suck clean air or oxygen by personal protection safety eyewear.
Valve 2 can be manually-operated gate 2 or electrically operated valve 2, as long as being that by 102 He of partition and connection air inlet
The effect of air outlet 103.In the present embodiment, valve 2 is configured as manually-operated gate 2, is set to the inner cavity 101 of shell 1
It is interior, and between air inlet 102 and corresponding air outlet 103.Due to using manually-operated gate 2, safety is higher, and
And keep distribution valve arrangement simple, it can reduce production and application cost.Valve 2 further includes handle 206, handle 206 and spool 201
It is connected as one, and handle 206 is rotated centered on its axis with movable valve plug 201, it is i.e. controllable by rotational handle 206
The on-off of valve 2 processed.The maximum rotation angle of handle 206 is 90 °.When the first ventilation opening of spool 201 rotates to left side in Fig. 3
Valve 2 shown in position when, the first ventilation opening is overlapped with the second ventilation opening, air inlet 102, inner cavity 101 and 103 phase of air outlet
Logical, valve 2 is opened, when being rotated by 90 ° on the basis of valve 2 on the left of Fig. 3, the first ventilation opening and the second vent position
Staggeredly, shown in the valve 2 on the right side of Fig. 3, valve 2 is closed at this time, and air inlet 102, inner cavity 101 are in air outlet 103 not to be joined
Logical state.
In order to improve the reliability of manually-operated gate 2, places 206 rotational angle of handle and position is more than scheduled range, valve
Door 2 further includes being set to for limiting the locating part 205 of the rotation angle of handle 206 on valve core case 203, what the present invention used
Locating part 205 is mechanical limit structure, such as stop screw.Stop screw can be opened what the handle 206 on valve core case 203 rotated
Beginning position and stop bits respectively install one, limit the direction of rotation extreme position of spool 201 in the position that valve 2 is fully opened or closed
Set, make spool 201 ensure will not be because of beyond the standard-sized sheet or entirely position closed.Meanwhile at the handle of two valves 2 206 also
There is switch sign, prompts the direction of user's controlled valve 2.
In addition, valve 2 further includes providing the damper 204 of damping for the rotation of spool 201, damper 204 and valve seat are solid
Fixed connection, in the present embodiment, damper 204 can be spring ball head screw, and spool 201 is made to rotate to standard-sized sheet or closed positions
When have a damping appropriate, i.e., guarantee standard-sized sheet or closed positions is accurate, and it is inclined to prevent the position in vibration of spool 201 from occurring
It moves.
In the present embodiment, the material of shell 1 is aluminium alloy, can reduce the overall weight of distributing valve, it is made to be easy installation
In vehicle cab or any position of equipment compartment, without considering the load-bearing problem of installation site, and it is small in size, it is at low cost.
The working principle of the present embodiment are as follows: clean air enters the inner cavity 101 of shell 1, inner cavity 101 by air inlet 102
In form positive pressure, then in environment pollute air will be unable to enter back into inner cavity 101, when operating personnel need in use, only needing to prevent
Face shield accesses air outlet 103, then opens valve 2, uses closing valve 2 when finishing.This instant form opened,
Can prevent the loss of clean air, and if clean air from protection shelter be directly accessed when, will not cause protect shelter in
The decline of superpressure.
More than, schematic description only of the invention, it will be recognized by those skilled in the art that without departing from work of the invention
On the basis of making principle, a variety of improvement can be made to the present invention, this is all belonged to the scope of protection of the present invention.
