Abstract
The utility model provides a differential pressure gauge used for measuring flows and flow velocity. The differential pressure gauge comprises an inclined fluid tube, a U-shaped tube, hydrostatic heads and a dynamic head. The U-shaped tube is arranged at the two ends of the inclined fluid tube, the hydrostatic heads are arranged at the connecting positions of the inclined fluid tube and the U-shaped tube, and the dynamic head is arranged in the U-shaped tube. The structure that the width is increased progressively is adopted for the arrangement of the inclined fluid tube, and the differential pressure gauge is simple in structure, firm, stable and reliable in performance, long in service life and low in cost.
Description
Technical field
The utility model is specifically related to the differential pressure gauge for the measurement of discharge flow velocity.
Background technology
differential pressure flowmeter is widely used in oil, chemical industry, metallurgical, electric power, heat supply, process control and the measurement in the fields such as water supply, orifice flowmeter is widely used in coal, chemical industry, traffic, building, light textile, food, medicine, agricultural, the national economy every field such as environmental protection and people's daily life, it is the development industrial and agricultural production, energy savings, improve production quality, increase economic efficiency and the important tool of management level occupies an important position in national economy, the defective that existing differential pressure flowmeter exists is: measuring error is large, complicated structure, cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to be provided for the differential pressure gauge of measurement of discharge flow velocity, and is simple in structure, and firm, stable and reliable for performance, the operating period limit for length, and cost is low.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: the differential pressure gauge that is used for the measurement of discharge flow velocity, comprise the inclination fluid hose, be connected to inclination fluid hose two ends the U-shaped pipe, be located at inclination fluid hose and U-shaped pipe junction statical head, be located at the dynamic head in the U-shaped pipe, described inclination fluid hose adopts width to increase progressively the structure setting.
As preferably, described U-shaped pipe two ends are connected with respectively the first crooked pipeline and the second crooked pipeline, described the first crooked pipeline is connected to the left end of inclination fluid hose, the second crooked pipeline is connected to the right-hand member of inclination fluid hose, this structure U-shaped pipe two ends also are provided with the first crooked pipeline and the second crooked pipeline that is communicated with the fluid hose that tilts, fluid is introduced into the first crooked pipeline and the second crooked pipeline has certain buffer action, improves the accuracy of measuring, and structure is more reasonable.
As preferably, described the first crooked pipeline is vertical with inclination fluid hose sidewall with the second crooked pipeline end, this structure the first crooked pipeline and the second crooked pipeline head are perpendicular to inclination fluid hose sidewall, and structure is more reasonable, further improve the accuracy of measuring flow velocity.
As preferably, described inclination fluid hose left end to right-hand member width increases progressively, the structure that this structure inclination fluid hose left end increases progressively to the right-hand member width, when fluid flow to right-hand member from the left end of inclination fluid hose, the dynamic head left end height of U-shaped pipe was less than the height of right-hand member, and difference in height is apart from increasing gradually, when fluid flow to left end from the right-hand member of inclination fluid hose, difference in height can calculate the flow velocity of liquid at this moment apart from reducing gradually, operates more convenient.
Beneficial effect:
The utility model employing technique scheme is provided for the differential pressure gauge of measurement of discharge flow velocity, and is simple in structure, and firm, stable and reliable for performance, the operating period limit for length, and cost is low.
