Greater impact is easily caused to valve component, valve body shakes and causes outlet to have some setbacks, and influences the normal use of fire extinguisher.
Utility model content
The utility model is to overcome above-mentioned deficiency of the prior art, there is provided one kind can effectively alleviate outlet impact
Air storage small steel cylinder formula extinguisher valve.
To achieve these goals, the utility model uses following technical scheme：
A kind of air storage small steel cylinder formula extinguisher valve, including small steel cylinder and the valve body installed in small steel cylinder bottle mouth position, institute
The bottom for stating valve body is provided with the air inlet connected with small steel cylinder inside, and the sidepiece of valve body is provided with gas outlet, and the inside of valve body is provided with
Air inlet and the air flue of gas outlet are connected, the top of valve body, which is provided with, can be cut off the rotational valve core that air flue connects, in described air flue
Provided with gas port, seal is provided between the rotational valve core and gas port, described seal includes can be with gas port top
The interior sealing pad coordinated and the external seal pad coordinated with gas port sealed bottom are sealed, is set between interior sealing pad and external seal pad
Flexible part.When rotational valve core rotating opening air inlet and gas outlet, interior sealing pad is divided by gas pressure with gas port
From subsequent external seal pad is separated with gas port, and so when rotational valve core is opened, the gases at high pressure in small steel cylinder will not be rushed directly
Enter to gas outlet, but entered back into after padding twice buffering by interior sealing pad and external seal in air flue, so as to prevent moment gas
Press through big and have influence on outlet, ensure outlet steady and smooth.
Preferably, described air flue is provided with projection in the lower end of rotational valve core, described gas port is located at raised central portion,
The raised bottom is provided with the bottom surface being connected with valve body, and the lower surface of the external seal pad is provided with the sealing with bottom surface
Circle.When rotational valve core closes air flue, for inner seal ring with being sealed at the top of gas port, exterior seal ring and the bottom surface of projection are close
Envelope, reaches double sealing effect, improves sealing property.
Preferably, the external seal pad lower end is provided with and surrounds raised cover body portion, described interior sealing pad is located at cover body
In portion, described elastic component is the spring being arranged between the bottom surface in cover body portion and interior sealing pad.So, when rotational valve core presses
When seal closes gas port, projection is enclosed in cover body portion by external seal pad, improves the sealing stability of seal.
Preferably, coordinate between described interior sealing pad and external seal pad for gap, the interior sealing pad and external seal
Interval area between pad is less than the circulation area of gas port.So, when rotational valve core opens air flue, air-flow is by interior sealing pad
After ejection, gas outlet is flow to along the gap between interior sealing pad and external seal pad so that outlet pressure becomes larger, further
Relax impact.
Preferably, the sidepiece of described valve body is provided with leakage port, the relief valve of threaded connection is provided with the leakage port
Core.
The beneficial effects of the utility model are：The sealing effectiveness of rotational valve core is improved, ensure that sealability, is delayed simultaneously
Outlet pressure when being opened with rotational valve core so that outlet process steady and smooth.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at seal in the utility model.
In figure：Small steel cylinder 1, pressure releasing valve core 2, valve body 3, leakage port 3a, gas outlet 3b, air flue 3c, gas port 3d, air inlet
3e, raised 3f, bottom surface 301, rotational valve core 4, seal 5, interior sealing pad 5a, external seal pad 5b, spring 5c, sealing ring 5d, cover
Body portion 501.
Embodiment
The utility model is further described with reference to the accompanying drawings and detailed description.
In embodiment as shown in Figure 1, a kind of air storage small steel cylinder formula extinguisher valve, including small steel cylinder 1 and be arranged on
