Description
Technical field
The utility model relates to a kind of flowmeter of unitized construction, is specifically related to integrated orifice-plate flowmeter.
Background technology
At present, orifice-plate flowmeter is used widely in the engineering fields such as oil, chemical industry, metallurgy, electric power.This flowmeter is mainly by pressuring throttling gear, pressure pipe, three valve groups, differential pressure transmitter and be used for holding in the palm support of putting and fixing three valve groups and differential pressure transmitter etc. to form.Wherein, pressuring throttling gear can be comprised of with the joining flange of engineering pipeline and the sandwiched orifice plate that is fixed between the flange a pair of.All be shaped with a radial direction through hole on each flange, this through hole consists of respectively its positive and negative pressure port; Three valve groups are comprised of positive and negative pressure measuring valve, a variable valve and the fluid passage that is made of exterior line that is arranged between each valve; To be an energy with the hydrodynamic pressure difference signal convert the electric signal of simulation to differential pressure transmitter and electric signal can be flowed to the chromacoder of terminal Displaying Meter.Use when installing, pressuring throttling gear passes through its flange welding between the pipeline butt end, be communicated with by pressure pipe respectively between positive and negative pressure port on it and the fluid input hole of positive and negative pressure measuring valve, the fluid delivery outlet of each pressure measuring valve and differential pressure become repeatedly between two pressure chambers of device and are communicated with by two exterior lines respectively, and variable valve is connected between this exterior line into and out of the hole by its fluid.This flowmeter Main Problems in manufacturing and use procedure is:
1, for a long time, owing to be subjected to the traditional mode of production mode, the particularly restriction of traditional make, flowmeter fails to form a kind of standardization of the integral structure that can directly produce, the approved product of seriation always in the worker is wide, but a kind of dispersion processing, field-installed indefinite form is product sternly, the building block that is flowmeter is made respectively by being dispersed in all parts of the country some professional production factory, then, purchased respectively according to engine request by the user, to the working-yard it is assembled into flowmeter again.This flowmeter is not only manufactured the cost height, and production efficiency is low, but also does not usually reduce it and manufacture quality because the constructor does not possess professional skill;
2, the pressuring throttling gear of existing flowmeter, three valve groups all exist in varying degrees loosely organized, the tie point position is waited construction problem more, cause flowmeter not only to be difficult to form the approved product of above-mentioned integral structure, but also exist that volume is large, the technological deficiency such as easy to leak, use are reliable not;
3, the differential pressure transmitter that uses of existing flowmeter does not all have temperature and pressure compensation, thereby can not eliminate the temperature of the fluid that is measured and pressure and change impact on the metering result.This allows the metered volume flow, and unallowed really for the metering mass rate.Therefore, existing flowmeter can only directly be measured fluid volume, and can not directly measure fluid mass.Under present condition, people will understand the mass rate timing, can only be take the volume flow value as basic parameter, and relend and help complicated mathematical operation and could realize, very bother thereby the gage work of mass rate is become, and result of calculation is also not accurate enough.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of compact conformation is provided, and not easy to leak, and energy is the integrated intelligent orificeplate mass flowmeter of meter fluid mass rate directly.
For achieving the above object, the technical solution of the utility model is the design integration orifice-plate flowmeter, it is characterized in that, described flowmeter comprises the orifice plate pressure obtaning device that is connected with pipeline, described orifice plate pressure obtaning device is connected by the input port of pipeline with three valve groups, and the output terminal of described three valve groups is connected with transmitter; In described orifice plate pressure obtaning device, be provided with temperature sensor.
Wherein preferred technical scheme is, described orifice plate pressure obtaning device comprises cylindrical shell, is provided with ring groove at the inwall of described cylindrical shell, is inlaid with dividing plate in described ring groove, is provided with through hole at described dividing plate, is provided with chamfering in a side of described through hole.
Further preferably technical scheme is, is provided with joint flange in the end of described cylindrical shell, is provided with sealing gasket between described joint flange and cylindrical shell.
Further preferred technical scheme also has, and is provided with valve at described pipeline.
Further preferred technical scheme also has, and described pipeline is provided with condensation coil between described valve and described three valve groups.
Preferred technical scheme also has, and described transmitter is differential pressure transmitter and/or pressure unit.
Advantage of the present utility model and beneficial effect are: this integrated orifice-plate flowmeter has:
1, it for people provide a kind of can in factory, directly make and be convenient to realize standardize, the flowmeter product of the integral structure of seriation, regularization, thereby not only be conducive to reduce the cost of manufacturing of flowmeter, quality is manufactured in assurance, and provides convenience for the user uses this product;
2, owing to the combination valve of three valve groups of the present utility model by monolithic construction consists of, omitted exterior line of the prior art; Pressuring throttling gear only is made of orifice plate again, omit the flange that arranges in the prior art and match with orifice plate and cancelled the support of putting three Fujian groups and differential pressure transmitter etc. that is used for holding in the palm of the prior art, thereby make the structure of whole product compacter, and reduce this tie point position of each parts, and then not only volume is little, lightweight but also easy to leak not to make the utility model, uses more reliable;
3, because the utility model has used the intelligent differential pressure transmitter with temperature and the complete dynamic auto compensation characteristic of pressure as chromacoder, so it is the direct volumetric flow rate of meter fluid not only, and the direct mass rate of meter fluid, thereby to bringing great convenience property of user.
