Abstract
The utility model provides a kind of liquid level gauge, particularly a kind of water-sealing fire-retardant venting of dust explosion device liquid level gauge, it comprises meter part and upper conduit and downcomer, the one end being connected water-sealing fire-retardant venting of dust explosion device at upper conduit with downcomer arranges reducing conduit respectively, is provided with and is communicated with joint between upper conduit and downcomer; The utility model can ensure under complex working condition that the display of meter part is normal, precisely and intuitively can observe the situation of change of its inner water seal height, ensure that equipment runs well and safety index.
Description
Technical field
The utility model relates to a kind of liquid level gauge, particularly a kind of water-sealing fire-retardant venting of dust explosion device liquid level gauge.
Background technology
At present, the existing liquid level gauge be used on coal-mine gas Cemented filling water-sealing fire-retardant venting of dust explosion device mainly contains three kinds: magnetic flap level gauge; Floating ball lever meter; Glass plate type leveler.
And existing liquid level gauge be used for water-sealing fire-retardant venting of dust explosion device time, after methane gas in mine gas drainage pipeline flows into water-sealing fire-retardant venting of dust explosion device, sealing water is wherein made to occur fluctuation, have a small amount of gas to pass through from ordinary level meter, make liquid fluctuating wherein, causing cannot the true water seal height of normal observation.
Utility model content
The purpose of this utility model is just to provide a kind of water-sealing fire-retardant venting of dust explosion device liquid level gauge, can be authentic and valid observe water seal height in water-sealing fire-retardant venting of dust explosion device, ensure the work of its normal safe.
The technical scheme that the utility model is adopted to achieve these goals is: a kind of water-sealing fire-retardant venting of dust explosion device liquid level gauge, comprise meter part and upper conduit and downcomer, it is characterized in that: described upper conduit is connected water-sealing fire-retardant venting of dust explosion device one end with downcomer arranges reducing conduit respectively, be provided with between upper conduit and downcomer and be communicated with joint.
The beneficial effects of the utility model are: the water-sealing fire-retardant venting of dust explosion device liquid level gauge after improving can ensure under complex working condition that the display of meter part is normal, precisely and intuitively can observe the situation of change of its inner water seal height, ensure that equipment runs well and safety index.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure 1, water-sealing fire-retardant venting of dust explosion device; 2, water is sealed; 3, meter part; 4, upper conduit; 5, downcomer; 6, reducing conduit; 7, joint is communicated with.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of water-sealing fire-retardant venting of dust explosion device liquid level gauge, as shown in Figure 1, comprise meter part 3 and upper conduit 4 and downcomer 5, the one end being connected water-sealing fire-retardant venting of dust explosion device 1 at upper conduit 4 with downcomer 5 arranges reducing conduit 6 respectively, is also provided with and is communicated with joint 7 between upper conduit 4 and downcomer 5, when water-sealing fire-retardant venting of dust explosion device 1 normally works, after methane gas in mine gas drainage pipeline flows into water-sealing fire-retardant venting of dust explosion device 1, there is fluctuation in the liquid level of sealing water 2, and portion gas flows through the meter part 3 of liquid level gauge, the liquid fluctuating of reducing conduit 6 from large to small on its sealing water 2 that now liquid level gauge upper conduit 4 is connected with downcomer 5 weakens the impact produced in the meter part 3 of liquid level gauge, a small amount of gas flowing into liquid level gauge also first can be back to water-sealing fire-retardant venting of dust explosion device 1 through being communicated with joint 7 simultaneously, effectively decrease the impact of air-flow on meter part 3 middle water level of liquid level gauge.
Claims (1)
1. a water-sealing fire-retardant venting of dust explosion device liquid level gauge, comprises meter part and upper conduit and downcomer, it is characterized in that: described upper conduit is connected water-sealing fire-retardant venting of dust explosion device one end with described downcomer arranges reducing conduit respectively; Be provided with between described upper conduit and described downcomer and be communicated with joint.
