The bottle valve is characterized in that a driving cylinder (4) is arranged outside the valve body (1) and is in contact with a rotating arm (5); the upper end of the rotating arm is hinged with a pressing arm (6); the pressing arm is connected with a compression screw (7); the compression screw is in contact with the upper end of the piston; a joint (8) which is communicated with the valve cavity is arranged on a side surface of the valve body (1); a valve cavity (9) is arranged on one side of the valve body, and a valve spring (10) is arranged in the valve cavity; the valve spring is connected with a valve assembly (11); a valve seat (12) is arranged on the outer side of the valve assembly; and a plug nut (13) is sleeved outside the valve seat.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment, especially relates to a kind of fire-fighting aerosol system bottle valve.
Background technique
Fire visit device by the pressurized container that extinguishing agent is housed promptly fire to visit bottle, vessel valve be that bottle valve and fiery inserting tube that can release fire suppression agent or releasing tube etc. are formed.With fiery inserting tube place near or above burning things which may cause a fire disaster most probable nidus, simultaneously, rely on along many sensing points of fiery inserting tube and survey.In case when catching fire; Under the temperature environment of 160 ℃ ± 2 ℃ (distances by protection equipment l rice scopes in) in 20 seconds; The fire inserting tube forms the injection hole by the automatic explosion of effect of pipe internal pressure, and firing-fighting medium is discharged into the protected area through fiery inserting tube itself or nozzle.Chinese patent discloses a kind of bottle valve structure of visiting the fire tube automatic fire extinguisher, and (notice of authorization number: CN201963979U), it comprises valve body, bonnet, and the bottom of valve body is import; The core of valve body is a valve pocket, and the cross section is that the spool of T type is divided into uuper valve chamber, lower valve chamber with valve pocket, and the top surface area of said spool is greater than bottom following table area; The sidepiece of valve body has interface, lower interface; Visit fire tube and connect said interface, the lower interface gone up, last interface is communicated with uuper valve chamber, and lower interface leads to import; The path between import, the lower interface is blocked in the spool bottom; The be threaded mounting hole at bonnet top of breaker bolt, the breaker bolt bottom is mounted on the cap core, and the upper-end surface of spool is being pressed in the lower end surface of cap core; Spring is mounted between the lower end surface of lower end surface and lower valve chamber of upper surface of spool; The lower end surface of bonnet has cap core mounting hole, and the cap core is loaded in the cap core mounting hole; O shape circle is installed between the inwall of cap core and bonnet, O shape circle is installed between the inwall of spool and valve body.But the structure of this bottle valve is comparatively complicated, and bottle valve pressure when work is less, is easy to generate fault.
The model utility content
The utility model provides a kind of fire-fighting aerosol system bottle valve, and it mainly is that to solve the structure of existing in prior technology bottle valve comparatively complicated, and bottle valve pressure when work is less, is easy to generate the technical problem of fault etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The fire-fighting aerosol system bottle valve of the utility model comprises valve body, is provided with valve pocket in the valve body; Be provided with piston in the valve pocket, described valve body outside is provided with the driving cylinder, and driving the cylinder contact has pivoted arm; The pivoted arm upper end is hinged with pressure arm, and pressure arm is connected with housing screw, housing screw contact piston upper end; The valve body side is provided with the joint that is communicated with valve pocket, and valve body one side is provided with the valve valve pocket, is provided with shutter spring in the valve valve pocket; Shutter spring connects valve assembly, and the valve assembly outside is provided with valve base, and valve base is socketed with the obstruction nut outward.Drive pivoted arm, pressure arm through driving cylinder, housing screw can press piston downwards, and after piston moved downward, the air-flow of moment can back down valve assembly, thereby backed down the obstruction nut, with gas release.
As preferably, be provided with plug screw on the described valve body, the piston cross-under is in plug screw.Be provided with the O RunddichtringO between plug screw and the piston.
As preferably, described valve pocket is communicated with safety vent, and safety vent is provided with blowout disk, and blowout disk is provided with safe pressure cap outward.Blowout disk can be pressed on the safety vent through pressure ring.
As preferably, described valve body connects pressure gauge through the GAUGE CONNECTOR assembly.Can observe bottle valve pressure inside size at any time through pressure gauge.
As preferably, described piston lower end is provided with seal ring.
Therefore, the structure of the utility model bottle valve is comparatively simple, and through driving the transmission of cylinder, pivoted arm, pressure arm, pressure is bigger, can not produce fault when work for bottle valve.
