Abstract
Disclosed is a laminar flow element. The laminar flow element is formed by embedding stainless steel thin tubes in cylindrical corrosion-resistant high-molecular material and is formed in a once-forming mode. The laminar flow element is characterized in that the inner diameter of each stainless steel thin tube is less than 1mm, the corrosion-resistant high-molecular material is teflon, the laminar flow element is pressed into a valve body and is in interference fit with the valve body, and pressure measuring tubes are arranged in front and back of the laminar flow element. The laminar flow element is convenient to install, high in production efficiency, capable of being used as a standard laminar flow element, stable and reliable in laminar flow effect, good in corrosion resistance, high in size use ratio and small in size. Due to the fact that the stainless steel thin tubes are used as the laminar flow element, the shortcoming that cone laminar flow elements are different in performance due to different flow rates is overcome in theory, sizes of the stainless steel thin tubes can be guaranteed, and reliability can be high in theory; and due to the fact that the stainless steel thin tubes are produced in a squeezed mode by adopting a large number of moulds, the inner diameter of each stainless steel thin tube is smooth, the sizes are standard and neat, and the produced laminar flow element is stable in laminar flow effect.
Description
Technical field
The utility model relates to a kind of flow device parts.
Background technology
The differential pressure flowmeter that laminar flow flowmeter is made up of laminar flow flow sensor and differential manometer is the instrument of measuring flow by the pressure reduction at survey sensor two ends.General laminar flow flowmeter is used for measuring the flow of tiny flow quantity and high powder degree fluid, and characteristics are that pressure reduction that flowmeter is sent is directly proportional with flow and are simple in structure.The pyramidal layer fluid element that adopts has the shortcoming of different flow different performance at present.
The utility model content
The utility model has solved the shortcoming that the tradition stratum fluid element has the different flow different performance, is fit to produce the laminar flow element that structured size is produced, laminar flow effect stability in batches.
Technical solutions of the utility model are to inlay the one-shot forming of stainless steel tubule to constitute laminar flow element in right cylinder corrosion resistance macromolecular material, concrete: below the stainless steel tubule internal diameter 1mm, cross sectional shape is circle or hexagon, the corrosion resistance macromolecular material is teflon, laminar flow element is pressed into valve inner, with the valve body interference fit, pressure pipe 1 is communicated with sensor respectively with pressure pipe 4 and imports and exports in the front and back of laminar flow element.
This structure has easy for installation, and what production efficiency was high and we innovate uses its laminar flow element as standard.The laminar flow effect stability is reliable, and the superior corrosion resistance energy is arranged, and the volume utilization height, compact size.Stainless-steel tube is as the advantage of laminar flow element, solved in theory and bored fluid element layer by layer, the shortcoming of different flow different performance, for example: certain tolerance underflow effect is better, can reach identical flow state if flow doubles so only need to double the quantity of stainless-steel tube, the size of stainless-steel tube is guaranteed, the reliability height is produced owing to adopt mould in enormous quantities to push in theory, and the internal diameter of stainless-steel tube is smooth, the laminar flow element that structured size is produced, the laminar flow effect stability.

Embodiment
Technical solutions of the utility model are to inlay stainless steel tubule 6 to constitute laminar flow element in right cylinder corrosion resistance macromolecular material 7, one-shot forming, concrete: below the stainless steel tubule 6 internal diameter 1mm, cross sectional shape is circle or hexagon, corrosion resistance macromolecular material 7 is teflon or the macromolecular material that satisfies client's needs, laminar flow element is pressed into valve inner, and with the valve body interference fit, the pressure pipe is communicated with sensor and imports and exports before and after laminar flow element.
The method that adopts directly adopts the corrosion resistance material for the design of tubulose integral type, carries out one-time formed laminar flow element design.As inserts, use the corrosion resistance macromolecular material to wrap up fully on every side stainless-steel tube.Form a poroid passage of cylindrical honeycomb capillary.Fluid is by passing through in each pore, and the laminar flow effect is better than the concentric-ring pattern pipeline.Guarantee that its state that flows through is laminar condition.The advantage of this design is, and is simple in structure, and the good rigidity through the stainless steel capillary of corrosion-resistant macromolecular material parcel is not subjected to the gas disturbance, the interference of exterior vibration.
The laminar flow element of brand-new design because outside surface is cylindrical structural, can be easily method by interference be fit into valve inner.Install simply, do not need debugging, produce the efficient height in batches.And after installing, impermeability is relatively good.The interference of vibration resistance and gas shock.
