The air chamber is communicated with an evacuation pipeline which is provided with an evacuation valve and is communicated with atmosphere. The liquid flow indicator is simple in structure and reasonable in design, no mechanical rotating device is needed, the liquid flowing condition can be conveniently and effectively judged, the defects of malfunction of the existing product due to corrosion or winding can be effectively overcome, meanwhile, the equipment failure rate is reduced, the equipment service life is prolonged, and the repair and maintenance costs of equipment are also lowered.
Description
Technical field
The utility model relates to a kind of straight-through visor, is specifically related to a kind of flow indicator that utilizes pressure balance principle, particularly the flow indicator in the sulfur removal technology.
Background technology
The flow indicator is widely used in the industrial installations such as cooling system, lubricating system, confession fuel system, pumping unit, oil, chemical industry, chemical fibre, medicine, food; Can observe the response situation of liquid flow at any time, be to guarantee the equipment operation indispensable accessory.Existing flow indicator has generally adopted mechanical rotation devices such as vane type, float-ball type, turnover plate type.Mechanical hook-up is installed in the liquid medium, and bearing is difficult to obtain good lubricated, is prone to twined and malfunctioning by impurity burn in the medium.Therefore, this indicator is had relatively high expectations to liquid pure cleanliness (water quality), be not suitable for the bigger liquid medium of corrosivity, and failure rate is higher in commercial Application, and it is big to repair maintenance workload.
The utility model content
The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of flow indicator that utilizes the pressure balance principle gaging pressure is provided, can be not malfunctioning because of corrosion or winding.
The utility model for realizing the technical scheme that technical purpose adopts is:
A kind of flow indicator comprises inlet pipeline, outlet conduit, observation pipeline, observes pipeline and is communicated with inlet pipeline and outlet conduit respectively.Inlet pipeline is equipped with imported valve, and outlet conduit is equipped with outlet valve.Observe pipeline and also comprise nozzle, view window and airtight air plenum.Nozzle is communicated with inlet pipeline and view window.Air plenum is communicated with emptying pipe, and emptying pipe is equipped with the emptying valve, and and atmosphere.Said nozzle outer wall and air plenum sealing welding.
A kind of flow indicator, said nozzle is a circular platform type, water delivering orifice is slightly less than water inlet.
A kind of flow indicator, said view window is processed by transparent material, and the window face indicates scale, demarcates fluid pressure.
A kind of flow indicator, the bearing capacity of said airtight air plenum is 2 times of liquid service pressure in the inlet pipeline.
A kind of flow indicator, said airtight air plenum is a rectangular parallelepiped, the front studs with transparent material.
A kind of flow indicator, said airtight air plenum is the cylinder transparent body, upper and lower surface is processed by metal material.
The beneficial effect of the utility model:
The utility model is simple in structure; Reasonable in design, need not any mechanical rotation device, can judge the liquid flow situation easily and effectively; Effectively overcome existing product because of corrosion or the malfunctioning shortcoming of winding; Reduce equipment failure rate simultaneously, prolonged service life of equipment, reduced the equipment repair maintenance cost.
Description of drawings
Fig. 1: the structural representation of the utility model.
Among the figure, inlet pipeline 1, outlet conduit 2 is observed pipeline 3, imported valve 4, outlet valve 5, nozzle 6, view window 7, air plenum 8, emptying pipe 9, emptying valve 10.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
Referring to Fig. 1, the flow indicator that the utility model provides comprises inlet pipeline 1, outlet conduit 2, observes pipeline 3, and said observation pipeline 3 is communicated with inlet pipeline 1 and outlet conduit 2 respectively.Inlet pipeline 1 is equipped with imported valve 4, and outlet conduit 2 is equipped with outlet valve 5.Observe pipeline 3 and comprise nozzle 6, view window 7 and airtight air plenum 8.Nozzle 6 is communicated with inlet pipeline 1 and view window 7.Air plenum 8 is communicated with emptying pipe 9, and emptying pipe 9 is equipped with emptying valve 10, and and atmosphere.
The flow indicator that the utility model provides, nozzle 6 can be designed as circular platform type, and water delivering orifice is slightly less than water inlet.Water inlet is optional with conventional connected modes such as flange, screw thread, welding, is connected with inlet channel 1.Nozzle 6 outer walls can weld with air plenum 8 sealings.
The flow indicator that the utility model provides, view window 7 can be processed by transparent materials commonly used such as glass, organic glass or transparent resins, and the window face indicates scale, in order to demarcate the pipeline fluid pressure.
The flow indicator that the utility model provides, airtight air plenum 8 can be 2 times of type selectings of liquid service pressure in the inlet pipeline 1 by its bearing capacity.Air plenum 8 can be transparent materials commonly used such as rectangular parallelepiped, front glazed, organic glass or transparent resin.Air plenum also can be right cylinder, and the side is processed by transparent materials commonly used such as glass, organic glass or transparent resins, and upper and lower surface is processed by metal material.Seal can be used nitrile rubber, conventional material such as teflon.
During work, open emptying valve 10 and imported valve 4 sequentially, treat that liquid is by emptying pipe 9 normal outflows after, close emptying valve 10.At this moment liquid level possibly after a while, opened outlet valve 5 in any position; At this moment liquid level can descend gradually; After treating the pressure and emptying pipe 9 fluid pressure balances after air compresses, liquid level stabilizing is then read the pipeline fluid pressure according to the corresponding scale of liquid level on the view window.Simultaneously, have or not liquid to flow out the unobstructed situation of judgement pipeline,, show that no liquid flows in the pipeline if there is not the fluid column ejection through observing nozzle 6.
