Description
Technical field
The utility model relates to a kind of propeller flowmeters.
Background technique
Propeller flowmeter is a kind of flowmeter that fluid flow is measured by its internal impeller angular velocity of rotation.Its principle
It is the linear relationship of the angular velocity of rotation and flow according to its internal impeller, after the angular velocity of rotation for measuring impeller, passes through it
The flowmeter of angular velocity of rotation measurement fluid flow valve.It is common to be applied in the instrument such as water meter, gas meter, generally include shell
Body, the impeller of setting in the housing and the induction chip for incuding impeller angular velocity of rotation, the shell include into water
Pipe and outlet pipe.
But the propeller flowmeter of the prior art, the aperture portion of water inlet pipe can not adjust automatically, be easy due to water flow too
It is small, impeller can not be pushed to be rotated, cause the flow measuring data error in later period larger, or since water flow is excessive, lead
Cause water inlet tracheal rupture, damage.
Utility model content
In view of the deficiencies of the prior art, the utility model provides one kind and can measure water inlet pipe aperture adjust automatically
More accurate, water inlet pipe does not allow the propeller flowmeter of easily rupturable damage.
To achieve the above object, the utility model provides a kind of propeller flowmeter, includes water inlet pipe, the water inlet pipe
In be embedded with flow compensation device, flow compensation device is whole in a tubular form and the first plug connector by being located at its water inlet end and position
The second plug connector in its water outlet is constituted, and is provided with an inner tube at the center of the second plug connector, is provided on the first plug connector
Flap component, flap component include along fluid flow direction gradually small busway, one end of flap component and the first grafting
The surrounding inner edge of part is connected, and the other end radial elastic of flap component is pressed on the outer circumference surface of inner tube.
By adopting the above technical scheme the advantages of, is: during fluid flows to impeller from busway, because of busway edge
Fluid flow direction gradually small setting, plays the effect of flow increasing, avoids impeller can not being pushed to be rotated since water flow is too small,
Cause the flow measuring data error in later period larger.Since the other end radial elastic of flap component is pressed on the excircle of inner tube
On face, when water flow is larger, flap component is radially expanded, and can be avoided the pressure mistake that water inlet pipe generates its inner wall due to fluid
Greatly, it is caused to rupture or damage.Compared with prior art, the propeller flowmeter of the utility model can be automatic according to the size of water flow
Aperture is adjusted, can guarantee that the water inlet pipe accurate, when water flow is excessive of measurement does not allow easily rupturable and damage when water flow is too small.
The utility model can be further arranged to: first plug connector and flap component are integrally formed and by elastic material
It constitutes, the flap component is made of the flap that multiple circumferential directions are distributed at the first plug connector inner peripheral wall, and the flap compresses
One end on the outer circumference surface of inner tube, which can be driven by water flow towards far from inner tube direction, to be moved.
By being further arranged, when several flap one ends are pressed on outer circumference surface, busway, busway are formed
When middle water flow is excessive, the direction that several one end being pressed on the outer circumference surface of inner tube are directed away from inner tube direction is swung, according to
The size adjust automatically of water flow, and structure is simple, it is easy to implement.
The utility model can be further arranged to: if being circumferentially evenly equipped in capable person at the flow-compensated piece of inner wall water outlet
Pipe is fixed on the connector of the center, and interval was formed with water space between adjacent connector.
By being further arranged, inner tube is arranged at flow-compensated piece of center, and inner tube is logical by fluid impact and fluid
The internal pressure in road can uniformly be shared by several connectors, avoided some connector load excessive and caused to damage, promote product
Stability.
The utility model can be further arranged to: the water inlet pipe is provided with annular step tread, institute at impeller one end
State flow-compensated piece support be located on annular step tread.
By being further arranged, annular step tread is positioned close at one section of impeller, it, will be flow-compensated when fluid enters
When block is pushed towards impeller direction, ring ladder forms support in face of it, prevents its excessive insertion to enclosure interior, and need
When by flow-compensated piece of taking-up, annular step tread does not form interference to it.
