Abstract
The utility model relates to a vortex street generating body integrated inserting type vortex street flowmeter, which is a flow measuring instrument for measuring the flow of liquid, gas and steam in a closed pipeline. The vortex street generating body is integrally inserted into a measured pipeline to form swirls, and a sensor is used for sampling and carrying out measurement. The vortex street flowmeter is arranged on a lug boss of a measured pipeline through a sealing assembly and a ball valve. After passing through the sealing assembly and the ball valve, the vortex street generating body is inserted into the measured pipeline. The utility model is suitable to be arranged in a pipeline with large diameter, occasions having the need of meter maintenance in time, and the work state of the pipeline can not be influenced at the time of maintenance. The utility model has the characteristics of novel structure, low cost, convenient installation and maintenance, etc., and thus the utility model belongs to a novel vortex street flowmeter which integrates economy and practicality.
Description
Technical field
The whole plug-in type vortex shedding flow meter of vortex shedder described in the utility model is a kind of flow measurement instrument that is used to measure liquid, gas and vapor flow rate in the closed conduct.
Background technology
The application of vortex shedding flow meter at present is very general, widely applies in industries such as oil, chemical industry, generatings.But with regard to the structure of the vortex shedding flow meter of present application and should be used for seeing and also have some problems.The one, at present the vortex shedding flow meter that uses is made monoblock type, need reserve the position of table body during installation, and the pipeline opening of front and back need be equipped with flange, connects with bolted, and installation and maintenance are very inconvenient, and must stop could to keep in repair after pipeline internal medium flows.The 2nd, vortex shedding flow meter need be made the vortex shedding flow meter of the various series of different tube diameters, and kind is numerous and diverse.The 3rd, though plug-type vortex shedding flow meter is also arranged at present, its structure still has some problems.The end of this vortex shedding flow meter insertion rod is equipped with a small-sized vortex shedding flow meter.This vortex shedding flow meter extend in the middle of the tested pipeline, its little vortex shedder makes measured medium produce whirlpool, and vortex shedding flow meter and external connecting part also make medium produce whirlpool in pipeline, two kinds of whirlpools interfere with each other, swinging of signal, tested precision is under some influence, and measurement data is inaccurate, poor reliability.At existing problem in the above-mentioned prior art, a kind of novel vortex shedding flow meter of research and design, existing problem is very necessary in the prior art thereby solve.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is the whole plug-in type vortex shedding flow meter of a kind of novel vortex shedder of research and design, solving existing installation and maintenance problem in the prior art, and problem such as existing plug-in type vortex shedding flow meter measuring error.The whole plug-in type vortex shedding flow meter of vortex shedder described in the utility model is made up of the vortex shedder of detecting amplifier and belt sensor; The vortex shedder of belt sensor passes seal assembly and ball valve injects among the tested pipeline, and ball valve is installed on the boss of tested pipeline, and seal assembly is contained in the ball valve upper end.The length of the vortex shedder of the whole plug-in type vortex shedding flow meter of vortex shedder described in the utility model should be complementary with tested pipeline, pushes up tube wall with the tail end of the vortex shedder of belt sensor and is advisable, and the length of tail end is selected according to different tube diameters.The whole plug-in type vortex shedding flow meter of vortex shedder described in the utility model is in the whole insertion of the vortex shedder tested pipeline, makes and produces whirlpool in the pipeline, delivers to detecting amplifier by the sensor acquisition signal.Vortex shedding flow meter described in the utility model only needs tested pipeline is opened a hole, and the installation base of burn-oning is loaded onto ball valve, seal assembly.Vortex shedder is passed seal assembly and ball valve is inserted in the tested pipeline, be contained in sensor in the vortex shedder and just the signal that records passed in the detecting amplifier and handle.The utility model provides a kind of novel vortex shedding flow meter, thereby has changed the structure and the installation form of existing vortex shedding flow meter.Make installation and maintenance convenient, measure more accurate.When in time carrying out instrument maintenance and maintenance, very suitable needs wish not influence the occasion use of pipeline duty.Because without watchcase, so when being used for the large diameter pipeline flow measurement, cost is starkly lower than whole vortex shedding flow meter.The utlity model has novel structure, cheap, installation and maintenance convenience, be more suitable for the characteristics such as measurement of large diameter pipeline rate-of flow, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
Description of drawings
The utility model has an accompanying drawing
The whole plug-in type vortex shedding flow meter of accompanying drawing 1 vortex shedder structural representation
Among the figure: 1, the vortex shedder 5 of detecting amplifier 2, seal assembly 3, ball valve 4, belt sensor, tested pipeline 6, installation base 7, tail end
Embodiment
Specific embodiment of the utility model is opened the hole that can insert the vortex shedder 4 of belt sensor as shown in drawings on tested pipeline 5, welded and installed boss 6 on the position in hole, and mounting ball valve 3 on installation base 6, and seal assembly 2 is installed on the ball valve 3.The vortex shedder 4 of belt sensor inserts from seal assembly 2, enters tested pipeline 5 through ball valve 3, runs into tube wall up to tail end 7 and gets final product.On the vortex shedder 4 of belt sensor tail end 7 is housed.Select the length of tail end 7 according to the caliber of tested pipeline 5.Cargo handling process of the present utility model is, unclamp sealing of seal assembly 2, belt sensor vortex shedder 4 is inserted, open ball valve 3 subsequently, the vortex shedder 4 of belt sensor is passed from the hole directly to be inserted in the tested pipeline 5, make tail end 7 touch tube wall, sealing of tight good seal assembly 2 gets final product.When pulling down the flux of vortex street timing, unclamp sealing of seal assembly 2 earlier, twitch the vortex shedder 4 of belt sensor, after tail end 7 is by ball valve 3, close ball valve 3, the vortex shedder 4 of extracting belt sensor then out gets final product.
