Description
Technical field
The utility model relates to a kind of fire-fighting equipment, especially relates to a kind of subway suppression system and uses 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 can't in time be worked when breaking out of fire, causes bigger security incident easily.
The model utility content
The utility model provides a kind of subway suppression system and uses bottle valve, and it mainly is that to solve the structure of existing in prior technology bottle valve comparatively complicated, and bottle valve can't in time be worked when breaking out of fire, causes the technical problem of bigger security incident etc. easily.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of subway suppression system of the utility model is used bottle valve, comprises valve body, and described valve body is provided with primary outlet; The valve body upper end is provided with capping, and the capping top is provided with end cap, is provided with piston in the valve body; Have the startup gas inlet on the valve body of piston top, piston top is connected with push rod, and the push rod top is provided with handle; Handle is fixed in the end cap through handle set, and the piston below is provided with valve assembly.When pressing active handle, drive cylinder and start working, make push rod be in free state, thereby after piston can move upward, the water of bottle valve bottom can be pumped in the valve pocket, water can spray from primary outlet.
As preferably, be provided with swivel nut between described piston and the valve assembly, be provided with sealing seat in the swivel nut, be provided with the sealing seat bar in the sealing seat, be provided with spring between sealing seat and the valve assembly.Spring can make valve assembly reset.
As preferably, be communicated with safety vent in the valve pocket of described valve body, 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, be communicated with GAUGE CONNECTOR in the valve pocket of described valve body, GAUGE CONNECTOR is socketed with gland nut outward.Pressure gauge can be monitored the pressure size in the valve pocket at any time.
Therefore, the structure of the utility model bottle valve is comparatively simple, during use, can inner spring formula valve inside be opened through handle, and it is comparatively timely to work.
