Description
Technical field
The utility model belongs to Technology of Level Detection field, specifically a kind of vane type fluid flow switch.
Background technique
In the prior art, when measuring the liquid level of working fluid in pipeline, vane type fluid flow switch, principle can be used
It is that blade is extend into pipeline, blade deflection is driven by liquid flow forces amount, thus trigger switch, then by external circuit etc.
The signal of monitoring switch, to learn the mobility status of liquid in pipeline.And drive blade deflection close by liquid level, flow velocity, fluid
The factors such as degree influence, so needing to correspond to scene when selecting fluid flow switch and carrying out more precision calculating, then to select
The switch of specific indexes.When installing at the scene, after needing to be installed completely, it just can be carried out and test whether suitably, if not
Suitably, then after needing fluid flow switch to remove, replacement or adjustment.It is relatively complicated when practice of construction.
Summary of the invention
To solve the above-mentioned problems, the utility model proposes a kind of new vane type fluid flow switch, including cylindrical outer casing, cylinders
Shape shell is provided with hollow inner prop, sleeve, blade and eccentric wheel；The bottom opening of cylindrical outer casing is opened on the side wall of open end
There is the screw thread for connecting tested pipeline；
Magnetic reed switch is connected in the hollow inner prop；Sleeve covers outside hollow inner prop, and sleeve is along the axis of hollow inner prop
It slides above and below in line direction；The top of sleeve is connected to the top of cylindrical outer casing；Magnetic corresponding with magnetic reed switch is housed on sleeve
Iron；
The bottom end of hollow inner prop is connected with shaft, and eccentric wheel is connected in shaft, and blade is connected on eccentric wheel；Shaft
Axis blade surface institute in the plane；The open end of sleeve is against on the outer wall of eccentric wheel, it is characterized in that the sleeve
Side wall is provided with notch, and notch extends to the top of sleeve from the bottom end of sleeve；The hollow inner prop is connected by the branch pipe on side wall
It is connected to cylindrical outer casing inner wall；(wiring of magnetic reed switch can be out of branch pipe through outside hollow body, and then is pierced by notch for branch pipe
Cylindrical outer casing).
Regulating mechanism is connected between sleeve and the top of cylindrical outer casing；
The regulating mechanism includes cavity, elastic balloon, slide plate, spring, baffle, connecting plate and air charging system；It is opened on baffle
There is through-hole, baffle is connected in cylindrical outer casing, and is parallel to the top surface of cylindrical outer casing, between baffle and the top surface of cylindrical outer casing
Space constitutes the cavity；
Elastic balloon is connected between slide plate and cavity top surface, bottom surface connecting spring one end of slide plate, and link block connects bullet
The other end of spring；Connecting rod between sleeve and connecting plate passes through the through-hole；
Tracheae perforation is provided on the wall of cavity, for tracheae in tracheae perforation, elastic balloon connects inflation dress by tracheae
It sets；Relief valve and pressure gauge are connected on tracheae.
The principles of the present invention are, by inflating the compression degree come spring to elastic balloon, to exist so as to adjust spring
Cavity original potential energy interiorly.When eccentric wheel is rotated with blade, sleeve is pushed up, and then compressed spring, at this time the original gesture of spring
Thrust suffered by capable of shifting up to sleeve and (coupling magnet and magnetic reed switch) is related, and this thrust is to be made with blade by liquid
It is firmly related.The advance and retreat of adjustment bolt can then adapt to the relationship between liquid and blade.
The air charging system is inflating balloon.
Inflating balloon can be connected by tracheae in the outside of fluid to be measured container, such as from the top of open container
Propelling container opens dedicated through-hole propelling container on hermetically sealed container.
Inflating balloon can be medical gas-filled sacculus, such as the medical gas-filled sacculus on sphygmomanometer, this sacculus band
There is a pair of of check valve, but also has relief valve and pointer pressure gauge.
Due to belonging to fine tuning to the air pressure in hollow conduit, hand-pinch type sacculus can be met the requirements.
Further, outer wall surface of the screw thread on the cylindrical outer casing side wall in cylindrical outer casing；In the outer wall of through-hole shell
It is equipped with annular ridge；The position of annular ridge is in the top of screw thread.
This fluid flow switch can go again after complete installation and finely tune, so that switch is suitable for the characteristic of situ liquid, more just
Victory requires the precision of the design selection of user not harsh.
