Abstract
The utility model provides a disposable valve which comprises a valve body and a valve core, wherein a first sealing ring and a second sealing ring are respectively sleeved at two ends of a pulling rod; the first sealing ring falls off while a valve rod is pressed, and the first sealing ring cannot be assembled again after the outlet air is used, so that the purpose of disposable use can be achieved. The second sealing ring is contacted with the valve body so as to achieve the sealing effect by pushing the valve rod under the effect of air pressure, and the traditional spring extruding and sealing mode is not used. The disposable valve has a simple structure, is easily produced and put into actual service, and has capacity of improving the safety of firefighting equipment.
Description
Technical field
The utility model relates to a kind of connected element, relates in particular to a kind of disposable valve, is used for fire-protection equipment.
Background technique
Fire-protection equipment like fire extinguisher, mostly is provided with valve, and the extinguishing material of pressured state is controlled.
The valve that uses at present all can use repeatedly.If the valve that uses repeatedly that will reclaim is installed on the fire extinguisher, with the airtight of valve and control usefulness are descended, causing wherein, the deactivation material slowly leaks totally.When the condition of a fire took place, fire extinguisher was difficult to play control action and affects the condition of a fire adversely.
The model utility content
For addressing the above problem, the utility model provides a kind of disposable valve, is beneficial to the safe handling of fire-protection equipment.
The technological scheme that the utility model adopts is following:
A kind of disposable valve comprises
Valve body comprises first holding cavity, second holding cavity and the 3rd holding cavity, and second holding cavity is between first holding cavity and the 3rd holding cavity, and the cross section of second holding cavity is all less than first holding cavity and the 3rd holding cavity;
Valve rod comprises bounding means and pull bar, and bounding means is located at the 3rd holding cavity, and the pull bar main body is located at second holding cavity, and the one of which end is connected with bounding means, and the other end is in first holding cavity;
First seal ring is located at the 3rd holding cavity, and is sheathed on pull bar one end;
Second seal ring is located at first holding cavity, and is sheathed on the pull bar the other end.
The utility model also comprises the clinkering filtering core device, is located at valve body one end, and is communicated with the 3rd holding cavity.
The utility model also comprises Sealing, is located in the valve body periphery, is provided with the 3rd seal ring in the Sealing.
The disposable valve that the utility model provides comprises valve body and spool, and first seal ring and second seal ring are sheathed on the pull bar two ends respectively, can't ressemble after valve is opened to reach disposable purpose.Simple in structure being easy to produced and practical application the Security of having reason to improve fire-protection equipment.
Description of drawings
Fig. 1 is disposable valve one embodiment's of the utility model a structural representation.
Embodiment
Below describe the technological scheme of the utility model in detail.The utility model embodiment only supplies to explain concrete structure, and the scale of this structure does not receive embodiment's restriction.
Embodiment
As shown in Figure 1, the disposable valve of the utility model comprises valve body 1 and valve rod 2.Valve body 1 comprises first holding cavity 11, second holding cavity 12 and the 3rd holding cavity 13, the second holding cavities 12 between first holding cavity 11 and the 3rd holding cavity 13, and the cross section of second holding cavity 12 is all less than first holding cavity 11 and the 3rd holding cavity 13.
Valve rod 2 comprises bounding means 21 and pull bar 22, and bounding means 21 is located at the 3rd holding cavity 13, and the pull bar main body is located at second holding cavity 12, and the one of which end is connected with bounding means 21, and the other end is in first holding cavity 11.First seal ring 3 is located at the 3rd holding cavity 13, and is sheathed on pull bar 22 1 ends; Second seal ring 4 is located at first holding cavity 11, and is sheathed on pull bar 22 the other ends.
When valve uses, depress 2 while of valve rod, first seal ring 3 and come off, first seal ring 3 can't be ressembled and reach disposable using effect after gas stream went out to finish using.After inflation, gas pressure promotion valve rod 2 makes second seal ring 4 contact with valve body 1 and plays seal action, do not re-use traditional spring crush seal.
Impurity in can filtering gas when filling gas causes bad reaction for avoiding getting in the bottle, be communicated with the place at valve body one end and with the 3rd holding cavity 13, and clinkering filtering core device 5 is set.
Valve body 1 periphery also is arranged with Sealing 6, is provided with the 3rd seal ring 61 in the Sealing, to improve the integral sealing effect after valve assembles.
