Abstract
The utility model discloses a coal gas flow meter. The coal gas flow meter comprises a measuring pipe installed in a coal gas pipeline, one end of the measuring pipe is of a cone structure and is arranged in the coal gas pipeline, and the other end of the measuring pipe extends to the outside of the coal gas pipeline; a flow dividing pipe is fixed to the end, arranged perpendicular to the measuring pipe and communicated with an inner pipe of the measuring pipe, the two ends of the flow dividing pipe are respectively provided with a rotary knob type control valve, and a plurality of collecting holes are evenly formed in the outer pipe wall of the section, extending to the coal gas pipeline, of the measuring pipe. The collecting holes are formed in the wall of the measuring pipe, so that dirt generated in the coal gas flowing process does not block one single collecting hole only, the collecting holes are effectively prevented from being blocked, and measurement accuracy still can be ensured after long-term use.
Description
Technical field
The utility model relates to a kind of gas flow meter.
Background technique
In coal gas, contain a certain amount of remaining coal tar oil, dust, water, these impurity very easily make measuring device occur bonding and stop up, the measuring accuracy of flow measuring device be can not be guaranteed, when serious, can make flow measuring device cannot normally work at all, dirty meeting produces error to the measurement of primary element, most of differential pressure flowmeter all need to insert primary element and vary in size and a little carry out the derivation of pressure for 2 pressure in pipeline, dust in coal gas, tar if the time slightly length will damage its pressure point, so metering that can not be steady in a long-term.The pressure-taking hole of primary transducer element also can produce and scabs and stop up under the effect of dirty especially fluid, the position of its obstruction is generally at the root of pressure-taking hole, because, the state of whole PRESSURE PIPE in blind chamber from pressure-taking hole to differential pressure transmitter, gas is immobilising in PRESSURE PIPE, along with the increase and decrease of differential pressure value, gas is just handled up near pilot port, and the dirty material in medium is easily in additional accumulating and form obstruction in pilot port.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and can effectively prevents from blocking, and guarantees to measure accurate gas flow meter.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of gas flow meter, comprise the sounding pipe of assigning in gas pipe line, described sounding pipe one end has cone structure, this end is arranged in gas pipe line, the other end extends to gas pipe line outside, and with this end on be fixed with a ram's horns, described ram's horns is vertical with sounding pipe to be arranged, and communicate with the inner tube of sounding pipe, the two ends of described ram's horns are provided with the control valve of a knob style, and described sounding pipe is evenly provided with several collection holes on it extends to the outer tube wall of that section of gas pipe line.
As preferred technological scheme, on the outer tube wall of described sounding pipe, be provided with first seal ring, the first seal ring is connected between sounding pipe and gas pipe line, the top of described the first seal ring is provided with the second seal ring of a ring-type, the second seal ring has recess, and described the first seal ring is buckled in this recess.
As preferred technological scheme, described the first seal ring top is provided with sealer.
As preferred technological scheme, the aperture of described collection hole is not more than 6mm.
The beneficial effects of the utility model are: this device by arranging multiple collection holes on the tube wall of sounding pipe, the dirt causing while making flow of gas is not just for single collection hole, effectively avoided collection hole obstruction, permanent use still can guarantee accuracy of measurement.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult a kind of gas flow meter shown in Fig. 1, comprise the sounding pipe 1 of assigning in gas pipe line, described sounding pipe 1 one end has cone structure, this end is arranged in gas pipe line, the other end extends to gas pipe line outside, and with this end on be fixed with a ram's horns 2, the setting vertical with sounding pipe 1 of described ram's horns 2, and communicate with the inner tube of sounding pipe 1, the two ends of described ram's horns 2 are provided with the control valve 3 of a knob style, and described sounding pipe 1 is evenly provided with several collection holes 101 on it extends to the outer tube wall of that section of gas pipe line.
Wherein, on the outer tube wall of described sounding pipe 1, be provided with first seal ring 4, the first seal ring 4 is connected between sounding pipe 1 and gas pipe line, the top of described the first seal ring 4 is provided with the second seal ring 5 of a ring-type, the second seal ring 5 has recess, and described the first seal ring 4 is buckled in this recess.
Described the first seal ring 4 tops are provided with sealer (not shown).
The aperture of described collection hole 101 is not more than 6mm.
The beneficial effects of the utility model are: this device by arranging multiple collection holes on the tube wall of sounding pipe, the dirt causing while making flow of gas is not just for single collection hole, effectively avoided collection hole obstruction, permanent use still can guarantee accuracy of measurement.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
