Abstract
A kind of fluid flow control method and device, it is characterized in that it is characterized in that a floating ball is arranged in a liquid pool with inlet and lower part liquid outlet, drawstring one end is connected on floating ball, the drawstring other end bypasses the pulley of liquid pool bottom successively, it is connected to after pulley at the top of liquid pool on the hose on the water outlet of liquid pool lower part, hose and the position of drawstring junction are less than liquid pool water level, the water outlet of hose is not higher than the position of hose and drawstring junction, external liquid is injected by inlet in liquid pool, liquid in liquid pool is flowed out from flexible pipe outlet, liquid pool fluctuation in stage, floating ball is also with lifting, floating ball drives hose synchronization lifting by drawstring, liquid pool liquid level is set to keep stablizing to hose and the vertical dimension,postural of drawstring junction, in this way, under stable hydraulic, the fluid flow of hose outflow also keeps stable.The present invention compared with the prior art, have the advantages that it is simple in structure, at low cost, woth no need to valve.
Description
Technical field：
The present invention relates to a kind of flow control techniques.
Background technology：
The method of existing accurate flow control is usually servo-type, i.e., according to the variation of the flow detected come control valve
Switch, to ensure that stability of flow, such control mode need flow quantity detection mechanism, control device and electrically operated valve, therefore, stream
The equipment cost for measuring control is high, moreover, cannot use cannot valvular situation.
Invention content：
The goal of the invention of the present invention is to provide a kind of fluid flow control method simple in structure, at low cost, woth no need to valve
And device.
Fluid present invention flow control methods are achieved in that in a liquid pool with inlet and lower part liquid outlet
One floating ball is set, and drawstring one end is connected on floating ball, and the drawstring other end is successively around the cunning at the top of the pulley of liquid pool bottom, liquid pool
It is connected to after wheel on the hose on the water outlet of liquid pool lower part, hose and the position of drawstring junction are less than liquid pool water level, hose
Water outlet is not higher than the position of hose and drawstring junction, and external liquid is injected by inlet in liquid pool, the liquid in liquid pool
Body is flowed out from flexible pipe outlet, liquid pool fluctuation in stage, and floating ball drives hose synchronization lifting by drawstring, make also with lifting, floating ball
Liquid pool liquid level keeps stablizing to hose and the vertical dimension,postural of drawstring junction, in this way, under stable hydraulic, hose outflow
Fluid flow also keeps stable.
Fluid present invention volume control device be achieved in that including with water inlet and lower part water outlet liquid pool,
Volume control device is particular in that volume control device includes floating ball, drawstring, hose, several pulleys, lower part in liquid pool
One pulley is at least set, a pulley is at least set outside liquid pool, hose is connected on the water outlet of liquid pool lower part, and floating ball is located at liquid pool
Interior, drawstring one end is connected on floating ball, and the drawstring other end connects after bypassing the pulley in liquid pool outside the pulley, liquid pool of lower part successively
On hose, makes tie point of the drawstring on hose less than liquid pool liquid level and be higher than liquid pool lower part water outlet.
Here, in order to ensure in hose that liquid flowing is smooth, the drawstring of hose is at the tie point on hose under liquid pool
It is socketed with spring ring between portion's water outlet.Due to there is spring ring, hose move up and down and when leading to bending, would not be curved
Folding, and hose is made to close, prevent liquid from flowing out.
The present invention compared with the prior art, due to can be achieved with stablizing woth no need to complicated servo-control mechanism of high cost
The control of flow, therefore, have the advantages that it is simple in structure, at low cost, woth no need to valve.
Description of the drawings：
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode：
The present invention is described in further detail in conjunction with drawings and examples：
As shown, fluid present invention volume control device is achieved in that including carrying water inlet 1 and lower part water outlet 2
Liquid pool 3, volume control device a, the top of liquid pool 3 is provided with overflow port 4, to ensure that 3 water level of liquid pool is no more than peak level,
It is particular in that volume control device a includes floating ball 5, drawstring 6, hose 7, several pulleys 8, and lower part setting is left in liquid pool 3
Right two pulleys 8,3 top of liquid pool are arranged two pulleys, and a lower part wherein pulley 8 is located at the underface of floating ball 5 in liquid pool 3, on liquid pool 3
A wherein pulley 8 in portion is located at the surface of another pulley in lower part in liquid pool 38, and another pulley 8 on 3 top of liquid pool is located at liquid pool 3
Outside, hose 7 is connected on 3 lower part water outlet 2 of liquid pool, and floating ball 5 is located in liquid pool 3, and 6 one end of drawstring is connected on floating ball 5,
6 other end of drawstring is successively above another pulley 8, liquid pool 3 around lower part in the wherein pulley 8, liquid pool 3 of lower part in liquid pool 3
A wherein pulley 8, be connected on hose 7 after another pulley 8 above liquid pool 3, keep tie point A of the drawstring 6 on hose 7 low
It is higher than 3 lower part water outlet 2 of liquid pool in 3 liquid level B of liquid pool.
The drawstring 6 of hose 7 is socketed with spring ring 9 at the tie point on hose 7 between 3 lower part water outlet 2 of liquid pool.
Fluid present invention flow control methods are achieved in that the liquid in liquid pool 3 exports outflow, liquid pool 3 from hose 7
Fluctuation in stage, floating ball 5 drive 7 synchronization lifting of hose by drawstring 6, make 3 liquid level B of liquid pool to hose 7 also with lifting, floating ball 5
It keeps stablizing with the vertical dimension,postural C at 6 tie point A of drawstring, in this way, under stable hydraulic, the fluid flow of the outflow of hose 7
Also it keeps stablizing.
