Abstract
A kind of velocity-averaging tube flow sensor, it comprises the impulse valve, mount pad and the test rod that are arranged in order from top to bottom, test rod is provided with pressure tap, the upper end of test rod is installed in the straight pipe of mount pad, mount pad is by Flange joint pressure guiding pipe, impulse valve is two, and the inlet side of two impulse valves is all connected with pressure guiding pipe by three-way pipe.Owing to have employed technique scheme, structure of the present utility model is simple, lightweight and use reliable, and it adopts insert type flow instrument, install very convenient, cost is low, without movable member, is specially adapted to low pressure heavy caliber round pipe or square pipe measurement of fluid flow.
Description
Technical field
The utility model relates to a kind of liquid, gas or flow measurement of steam device.
Background technology
Existing flowrate measuring tool is generally used in high-pressure large-caliber pipeline, carries out flow measurement to the liquid in pipeline, gas or steam, and inconvenience installed by current measuring instrument, parts are more, complex structure, heavier-weight, is not easy to low pressure heavy caliber round pipe or square pipe measurement of fluid flow.
Utility model content
The utility model provides a kind of structure simple, lightweight and service-strong velocity-averaging tube flow sensor, it adopts insert type flow instrument, and install very convenient, cost is low, without movable member, be specially adapted to low pressure heavy caliber round pipe or square pipe measurement of fluid flow.
The utility model realizes goal of the invention by the following technical solutions, a kind of velocity-averaging tube flow sensor, it comprises the impulse valve, mount pad and the test rod that are arranged in order from top to bottom, test rod is provided with pressure tap, the upper end of test rod is installed in the straight pipe of mount pad, mount pad is by Flange joint pressure guiding pipe, and impulse valve is two, and the inlet side of two impulse valves is all connected with pressure guiding pipe by three-way pipe.
Further, test rod inserts in pipeline, and the upper end of test rod is by nut, and bottom can be suspended in pipeline, also can be supported in pipeline lower end.
Further, the pressure tap on test rod is four.
Owing to have employed technique scheme, structure of the present utility model is simple, lightweight and use reliable, and it adopts insert type flow instrument, install very convenient, cost is low, without movable member, is specially adapted to low pressure heavy caliber round pipe or square pipe measurement of fluid flow.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is further explained.
A kind of velocity-averaging tube flow sensor, it is characterized in that, it comprises the impulse valve 1, mount pad 2 and the test rod 3 that are arranged in order from top to bottom, test rod 3 is provided with pressure tap 4, the upper end of test rod 3 is installed in the straight pipe of mount pad 2, mount pad 2 is by Flange joint pressure guiding pipe 5, and impulse valve 1 is two, and the inlet side of two impulse valves 1 is all connected with pressure guiding pipe 5 by three-way pipe 6.
During concrete use, can process a diameter on the wall of Pipe installing position is the hole of 40mm, then mount pad is vertically mounted on pipeline, again test rod 3 to be inserted from the hole that diameter is 40mm in pipeline and straight cutting to inner-walls of duct, tighten nut on mount pad straight pipe again to screw test rod, test rod need make the flow direction of pressure tap and fluids within pipes be consistent after installing.
Further, test rod inserts in pipeline, and the upper end of test rod is by nut, and bottom can be suspended in pipeline, also can be supported in pipeline lower end.
Mount pad 2 also can be connected with pressure guiding pipe 5 by nut.
Further raising Detection results, the pressure tap on test rod is four.
