Abstract
The utility model provides a novel mining wind pressure survey device improves on the basis of original water column meter, and is main includes four exports of U type water column meter, fixing device and U type water column meter, four exports of are static pressure interface, total head interface, total head export, static pressure export respectively, four exports all through the valve control its open with the closed condition to close and open the condition through what adjust these valves, realize the survey to mine static pressure, total head and dynamic pressure, for original wind pressure survey device, a novel mining wind pressure survey device has the gas tightness height, and analysis results is accurate, easy operation, the advantage of easily carrying.
Description
Technical field
A kind of new type mining blast surveys device, relates to mine ventilation field.
Background technology
Blast mensuration is the basic work of mine ventilation, identifies Mine Ventilator performance, selects the work such as air duct parameter to be required to be measured method of Mine Ventilation pressure；It is the bubble-tight quality of device that impact measures the principal element of accuracy, traditional method is that pitot tube connects U-shaped water column meter by sebific duct, pitot tube insert distinguished and admirable in, the pressure reduction observing U-shaped water column meter is measured, this method needs plug sebific duct back and forth, poor air-tightness, complex operation, measurement result is inaccurate.
Summary of the invention
For overcoming the shortcoming of tradition assay method, on the basis of U-shaped water column meter, a kind of new type mining blast determinator of design, has air-tightness high, and measurement result is accurate, simple to operate, portative advantage.
A kind of new type mining blast determinator, it is characterised in that embedded by U-shaped water column meter in fixing device, U-shaped water column meter one end is provided with static pressure interface and total head outlet, and total head outlet is passed through air；The U-shaped water column meter other end is provided with total head interface and Static pressure outlet, and Static pressure outlet is passed through air；All by Valve controlling, it is opened and Guan Bi situation for the outlet of static pressure interface, total head, total head interface, Static pressure outlet；The two of pitot tube sebific ducts are connected with total head interface, the static pressure interface of this device respectively, by closing and these valves can be opened, it is achieved the mensuration to mine static pressure, total head and dynamic pressure.
Accompanying drawing explanation
Fig. 1 is a kind of new type mining blast determinator schematic diagram；
In figure, 1-fixing device；2-water column meter；3-static pressure interface；4-total head interface；5-the first valve；6-the second valve；7-the 3rd valve；8-the 4th valve；9-total head exports；10-Static pressure outlet.
Detailed description of the invention
A kind of new type mining blast determinator schematic diagram as shown in Figure 1, it is first shut off the second valve 6 and the 3rd valve 7, opens the first valve 5 and the 4th valve 8, in U-shaped water column meter, inject appropriate water, it is then turned off the first valve 5 and the 4th valve 8, and records initial level registration；The two of pitot tube sebific ducts are connected with static pressure interface 3, the total head interface 4 of this device respectively.
When measuring mine static pressure, opening the first valve 5 and the 3rd valve 7, close the second valve 6 and the 4th valve 8, at this moment water column meter one end liquid level is passed through air by hydrostatic pressure, the other end by Static pressure outlet 10, and by atmospheric pressure effect, record liquid level is poor, is static pressure.
When measuring mine total head, opening the second valve 6 and the 4th valve 8, close the first valve 5 and the 3rd valve 7, at this moment water column meter one end liquid level is passed through air by total head effect, the other end by total head outlet 9, and by atmospheric pressure effect, record liquid level is poor, is total head.
When measuring mine dynamic pressure, opening the first valve 5 and the 4th valve 8, close the second valve 6 and the 3rd valve 7, at this moment water column meter one end liquid level is by hydrostatic pressure, and the other end is by total head effect, and record liquid level is poor, is dynamic pressure.
