Abstract
The utility model relates to a gas pipeline technology field relates to a gas monitoring valve well lid structure. Including the well lid body, be equipped with alarm and gas concentration detection device on the well lid body, the gas concentration detection device links to each other with the alarm. The interior natural gas concentration of valve well not only can be surveyed on having integrated the concentration detection device valve well's well lid to this well lid structure, can save the valve well inner space moreover, makes things convenient for the staff to pass in and out valve well.
Description
Technical field
The utility model relates to technology of gas pipeline field, relates to a kind of gas monitoring valve manhole cover structure.
Background technology
Natural gas belongs to flammable explosive gas, and natural gas line spreads all over whole city, and the valve well One's name is legion particularly in the gas pipeline of city, objectively exists potential safety hazard.Based on the safety requirements that natural gas transmission and distribution is alleviated, be necessary that carrying out timing to the confined space of pipeline network of fuel gas in city underground pipeline detects, to ensure gas company's property and civic life security.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of gas monitoring valve manhole cover structure.
In order to reach above-mentioned utility model object, the utility model by the following technical solutions:
A kind of gas monitoring valve manhole cover structure, comprise manhole cover body, described manhole cover body is provided with alarm and gas concentration detection apparatus, and described gas concentration detection apparatus is connected with alarm.
Gas concentration detection apparatus can carry out concentration monitor to the gas in valve well in real time, as the monitoring of methane concentration, or the monitoring of other explosion hazard gases, when the concentration that this gas concentration detection apparatus monitors in valve well exceedes desired value, energizes alarm is reported to the police.
Preferably, described manhole cover body is also provided with controller.
Controller is to the setting of target monitoring concentration, and the alarm condition of alarm and the ventilation closing window of subsequent formulation and wireless transmission signal device control
Preferably, described manhole cover body Shanghai is provided with air vent, and air vent is provided with ventilation closing window, and described ventilation closing window is connected with controller.
When the explosion hazard gases concentration in valve well reaches certain value, in order to prevent setting off an explosion, controller controls ventilation closing window and ventilates, thus reduces the gas concentration in valve well, reduces and fires critical point.
Preferably, described manhole cover body is provided with wireless transmission signal device, and wireless transmission signal device is connected with controller.
Signal generator under the control of the controller real-time to the feedback of status in valve well to administrative center.
Compared with prior art, beneficial effect is the utility model:
1 concentration detection apparatus has been incorporated on the well lid of valve well, can not only detect concentration of natural gas in valve well, and can save valve well inner space, facilitate staff to pass in and out valve well;
2 can feed back other concentration informations in valve well in time, help administrative staff to understand concrete condition in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 manhole cover body, 2 alarms, 3 gas concentration detection apparatus, 4 controllers, 5 air vents, 6 ventilation closing windows, 7 wireless transmission signal devices.
Detailed description of the invention
Below by specific embodiment, explanation is further described to the technical solution of the utility model.
Embodiment:
A kind of gas monitoring valve manhole cover structure, as shown in Figure 1, comprise manhole cover body 1, described manhole cover body 1 is provided with alarm 2, gas concentration detection apparatus 3, controller 4, wireless transmission signal device 7, manhole cover body 1 is also provided with air vent 5 simultaneously, air vent 5 is provided with ventilation closing window 6, and gas concentration detection apparatus 3 is connected with alarm 2, and ventilate closing window 6, wireless transmission signal device 7 of alarm 2, gas concentration detection apparatus 3 is all connected with controller 4.
Gas concentration in gas concentration detection apparatus 3 pairs of valve wells is monitored, especially the monitoring of explosion hazard gases, when gas concentration reaches default warning value, start warning device by controller 4 to report to the police, simultaneously, controller 4 can control to ventilate the opening and closing of closing window 6 to evacuate the gas in valve well, avoids these gases to reach to fire and a little blast.In addition, controller 4 controls wireless transmission signal device 7 real time emission wireless signal, the gas station in valve well is sent to administrative center, is convenient to the real-time management to valve well.
