Description
Technical field
The utility model is related to gas extinguishing system field, and high envelope valve is let out more particularly, to one kind is low.
Background technology
It is low to let out high envelope valve, it is to use on the combined distribution system torrent pipeline in fire-fighting system and on driving gas piping
Release the control valve of gas.
It is low to let out high envelope valve for discharging the driving gas that container value chronic leak goes out, prevent driving gas in control piper
Accumulation, makes gas starter misoperation, but if safeguarding not in time, and the leakage for a long time of driving gas is being produced without timely pressurising
Fire is insufficient pressure and extinguishing chemical bottle group of not opening, and can make catastrophic consequence.
Utility model content
For the deficiency in the presence of prior art, the utility model provides a kind of low height of letting out and seals valve, and it can be
Being warned during low-pressure leak occurs in system, to remind staff to carry out upkeep operation in time.
To achieve the above object, the utility model employs following technical scheme：A kind of low height of letting out seals valve, and it includes：
Valve body, its underpart, which is provided with air chamber, valve body, is provided with valve, and valve is provided with air inlet, and the top of valve body, which is provided with, to be taken out of
Spring is installed between the vertical air flue and valve that are communicated in the joint of gas passage, joint with outlet passageway；It also includes：It is installed on
It is provided with above activity template and the device of warning for being installed on joint in joint at the top of vertical air flue, activity template and is arranged at joint
Power supply, the first electrode of power supply and device electric connection of warning, can push activity template to when system low-voltage is leaked the of power supply
Two electrodes, so that connecting device and the power supply and allowing of warning device of warning sends warning signal.
Compared with prior art, the low high envelope valve of letting out that the utility model is provided can be when system low-voltage be leaked in time to work
Make personnel to be warned, so as to allow system effectively to be safeguarded in time, it is to avoid fire can not open extinguishing chemical bottle when occurring
The problem of group.
Further, device of warning is buzzer or warning light.
Further, power supply is lithium battery.
Further, joint is provided with the lithium battery installation passage above vertical air flue, and the lithium battery installation passage is set
Lithium battery cushion cap is equipped with, lithium battery top is provided with battery cover board.
Further, activity template is movably installed in vertical air flue by wire, and the wire is connected with device of warning.
Brief description of the drawings
Fig. 1 seals valve arrangement schematic diagram for a kind of low height of letting out in the utility model；
Fig. 2 is enlarged drawing at I in Fig. 1.
Embodiment
Embodiment：Referring to Fig. 1, a kind of low height of letting out seals valve, and it includes：Valve body 1, its underpart is provided with air chamber 11, valve body
Valve 2 is installed, valve is provided with air inlet 10, and the top of valve body is provided with the joint 9 of outlet passageway 5, joint with going out
Spring 3 is installed between vertical air flue and valve that gas passage is communicated, said structure is prior art, and not in this to go forth.
Referring to Fig. 2, low high envelope valve of letting out also includes：It is installed on activity template 8 in joint at the top of vertical air flue and is installed on and connects
The device 7 of warning of head, device of warning is to be provided with the power supply 4 for being arranged at joint, example above buzzer or warning light, activity template
The power supply being such as made up of lithium battery, makes full use of the characteristic of flat lithium battery and is conveniently installed in joint here,
The first electrode (positive pole) of lithium battery and device electric connection of warning, activity template can be pushed to power supply when system low-voltage is leaked
Second electrode (negative pole), so that connecting device and the power supply and allowing of warning device of warning sends warning signal.
From the discussion above it is seen that, activity template moves up and connects whole circuit of warning when system low-voltage is leaked, with timely
Staff is warned.
Continue as shown in Figure 2, joint is provided with the lithium battery installation passage above vertical air flue, the lithium battery is installed
Passage is provided with lithium battery cushion cap, and to improve the stability after lithium battery is installed in place, lithium battery top is provided with battery cover board
6, certainly, the battery cover board can set corresponding sealing structure, also, battery cover board here can be opened easily with more
Change lithium battery.Lithium battery 4 is connected with battery cover board 6, and battery cover board is connected with buzzer, and (one end of buzzer 7 is connected battery cover board
6, one end connection activity template 8), so as to constitute complete circuit of warning, the circuit is connected by activity template.Lithium battery and battery cover
The spring for being fixed on battery cover board can be set between plate, the spring is resisted against lithium battery, it is to avoid lithium when between the two with gap
After battery displacement activity template can not be allowed to connect and influence alarm.
And activity template can be movably installed in vertical air flue by wire, the wire is connected with device 7 of warning, and leads here
The diameter of line can not be too big, and circuit of warning is connected in order to activity template be promoted to move up when gas leakage occurs.
During work, when system low-voltage is leaked, leakage gas enters from air chamber 11, promotes activity template 8 to move up by air inlet 10,
Activity template 8 and lithium battery 4 are connected, the work alarm of buzzer 7.When system high pressure is run, gases at high pressure enter from air chamber 11, high pressure
Gas overcomes the active force of spring 3 to promote valve 2 to move upwards, and valve 2 and valve body 1 are sealed, and valve body is closed.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
