Abstract
The utility model discloses a reation kettle pipeline sight glass, including looking the pipe, look tub both ends and be equipped with and be used for the fixed ring flange of looking the pipe, characterized by: looking and being equipped with the feed liquor pipe on the ring flange of tub upper end, feed liquor pipe one end is equipped with the contraction section, inside the contraction section inserts the sight glass, under the contraction section terminal surface with look one section distance at the interval between the pipe time terminal surface. This reation kettle pipeline sight glass, simple structure to eliminate liquid wall built -up phenomenon effectively, make things convenient for operating personnel accurately to hold the interior liquid flow condition of pipeline.
Description
Technical field
The utility model relates to a kind of pipeline viewing mirror, and more particularly, it relates to a kind of reactor pipeline viewing mirror.
Background technique
Pipeline viewing mirror is one of main accessories on industrial pipeline device, can observe liquid medium flow response situation in pipeline at any time by it, monitors and produces, and avoids accident in production process to occur.Produce in pipeline through being usually used in oil, chemical industry, chemical fibre, pharmacy etc.Existing visor generally comprises transparent looks pipe, being provided with for sealing the flange plate fixedly looking pipe, being bolted between two flange plate depending on pipe two ends.Operationally often there is liquid wall cling phenomenon in existing pipeline viewing mirror, along looking pipe internal surface flowing, making operator can not determine the size of fluid flow in pipeline, affecting the adjustment for reaction process.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of pipeline viewing mirror, can effectively eliminate liquid wall cling phenomenon, and easy-to-operat personnel hold flow of fluid situation in pipeline exactly.
For achieving the above object, the utility model provides following technological scheme: a kind of pipeline viewing mirror, comprise and look pipe, the flange plate for fixedly looking pipe is provided with depending on pipe two ends, flange plate depending on pipe upper end is provided with liquid inlet pipe, and the flange plate depending on pipe lower end is provided with drain pipe, and liquid inlet pipe one end is provided with contraction section, it is inner that contraction section inserts visor, contraction section lower end surface and depending on being spaced a distance between pipe lower end surface.
The utility model is preferred: described contraction section comprises conical section and vertical section, and the large end of conical section is connected with liquid inlet pipe, and conical section small end is connected with vertical section.
The utility model is preferred: described contraction section lower end surface is look pipe height 1/2 ~ 2/3 to the distance depending on pipe lower end surface.
The utility model is preferred: described liquid inlet pipe and drain pipe are equipped with by-pass cock.
The utility model is preferred: described liquid inlet pipe and drain pipe are made by PVDF material.
Compared with prior art, the beneficial effects of the utility model are: liquid inlet pipe one end is provided with contraction section, contraction section stretches into looks pipe inside, when the liquid of coming from liquid inlet pipe flows through contraction section, diameter diminishes, and with depending on inner tube wall do not contact, effectively prevent the generation of liquid stream wall cling phenomenon, generally can also be estimated the flow of liquid stream by the flow condition of liquid stream, suitably control the speed of liquid stream.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model reactor pipeline viewing mirror.
Reference character: 1, look pipe; 2, flange plate; 21, annular groove; 22, annular lug; 3, bolt; 4, liquid inlet pipe; 41, contraction section; 411, conical section; 412, vertical section; 5, drain pipe; 6, by-pass cock.
Embodiment
With reference to Fig. 1, the utility model reactor pipeline viewing mirror embodiment is described further.
A kind of reactor pipeline viewing mirror, comprise and look pipe 1, be made up of transparent plastics depending on pipe 1, the flange plate 2 for fixedly looking pipe is provided with depending on pipe 1 two ends, to be fixed on flange plate 2 depending on pipe 1 by bolt 3 between two flange plate, flange plate 2 is provided with annular groove 21 and the annular lug 22 adjacent with annular groove 21, can be stuck in groove depending on pipe, fit depending on pipe 1 outer wall and annular lug 22, flange plate depending on pipe 1 upper end is provided with liquid inlet pipe 4, liquid inlet pipe 4 one end is provided with contraction section 41, contraction section 41 inserts visor inside, contraction section 41 lower end surface and depending on being spaced a distance between pipe lower end surface.When liquid stream flows into liquid inlet pipe 4, liquid flow diameter shrinks at the contraction section 41 of liquid inlet pipe 4, liquid flow diameter diminishes, and depending on being spaced a distance between pipe 1 inwall, when liquid flows through can not with look pipe 1 contact internal walls, avoid producing liquid stream wall cling phenomenon, causing cannot from the flow condition depending on clearly observing liquid stream pipe 1.
Contraction section 41 comprises conical section 411 and vertical section 412, and conical section 411 greatly end is connected with liquid inlet pipe 4, and conical section 411 small end is connected with vertical section 412.Liquid flow diameter is by reducing gradually during conical section 411, avoid producing turbulent flow, the vertical section 412 be connected with conical section 411 small end plays leading role further, makes liquid stream enter drain pipe 5 vertically, directly pour in reactor, the spray that minimizing liquid stream splashes hangs over looks inner tube wall.
Contraction section 31 lower end surface is look pipe height 1/2 ~ 2/3 to the distance depending on pipe 1 lower end surface.If contraction section 31 lower end surface is too large to the distance of looking between pipe 1 lower end surface, then liquid fluid capacitance easily sputters spray, although can observe liquid flowing state clearly, can produce the current mark of trace depending on pipe 1 lower end; If contraction section 31 lower end surface is too little to the distance of looking between pipe lower end surface, then can reduce the height of viewing section, the flow velocity of liquid stream can not be estimated well.
Described liquid inlet pipe 4 and drain pipe 5 are equipped with by-pass cock 6.By-pass cock 6 can according to actual needs for controlling the flow velocity of liquid stream.Switch when reacting in reactor on drain pipe 5 cuts out, and can prevent the gas produced in reactor from running out of from drain pipe 5.
Liquid inlet pipe and drain pipe are made by PVDF material, and PVDF has in fluoroplastic that most obdurability, low coefficient of friction, corrosion resistance are strong, ageing resistance, weatherability, the features such as radiation-resistant property is good.Effectively can extend the working life of visor.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
