Detailed Description
The present invention will now be described in detail with reference to the drawings and specific embodiments, wherein the exemplary embodiments and descriptions are provided only for the purpose of illustrating the present invention and are not to be construed as limiting the present invention.
As shown in fig. 1, the injection hose flow rate controller according to the present embodiment includes a base 1, a second U-shaped groove 6, a screw 7, and a rotary cap 8; a second U-shaped groove 6 is arranged in the base body 1; the screw 7 is in threaded movable connection with the second U-shaped groove 6; the screw 7 is integrally formed with a disk-shaped rotary cap 8, and the screw 7 is located at the center of the rotary cap 8.
Further: it also comprises a first U-shaped groove 2; a spring 3 and a graduated rod 4; a first U-shaped groove 2 is positioned in the base body 1; the opening directions of the first U-shaped groove 2 and the second U-shaped groove 6 are the same; the spring 3 is positioned in the first U-shaped groove 2; the part of the scale rod 4 is positioned in the first U-shaped groove 2, the scale rod 4 blocks the spring 3, scale marks are arranged on the scale rod 4 in a surrounding mode, and the zero point of each scale mark is the position where the outermost end of the scale rod 4 is attached to the rotating cap; the rotary cap 8 blocks the graduated rod 4; the scale bar 4 moves in and out of the first U-shaped groove 2 with the rotation of the rotary cap 8.
Further: the matrix 1 is a cuboid made of degradable plastics; the side face of the cuboid is perpendicular to the scale rod, and scales on the scale rod can be read conveniently.
Further: the annular surface of the rotating cap 8 is provided with anti-skid grains; the provision of the non-slip threads provides a greater coefficient of friction to facilitate manual rotation of the screw cap 8.
The flow rate controller of the injection hose of the invention has the working principle that: the flow rate controller can be stored separately from the injection hose 5, when the injection hose 5 is used for dropping liquid, the screw cap 8 is rotated, the screw 7 and the rotating cap 8 are detached from the second U-shaped groove 6, then the injection hose 5 is placed into the second U-shaped groove 6 from the opening of the second U-shaped groove 6, the screw 7 is rotated to the opening of the second U-shaped groove 6, then the screw cap 8 is continuously rotated to push the screw 7, the screw 7 extrudes the injection hose 5 in the pushing process, the injection hose 5 is deformed, and the rate of the liquid medicine passing through the injection hose 5 is adjusted. After the injection is completed, the injection hose 5 is detached, the screw 7 is then screwed off, the injection hose 5 is taken out of the opening of the second U-shaped groove 6 and discarded, and the screw 7 is reinstalled into the second U-shaped groove 6 for the next use.
Repeatedly carrying out a large number of experiments according to the injection hose 5 with the matched diameter when the controller is manufactured, dripping water by using the injection hose 5 during the experiments, then adjusting the length of the screw 7 in the second U-shaped groove 6, extruding the injection hose 5, recording the flow within a certain time, and making scale marks on the scale rod 4 at the junction of the scale rod 4 and the opening of the first U-shaped groove 2; and then, the screw 7 is pushed tightly again, the flow is repeatedly recorded, and the scale marks are made until the injection hose 5 is completely squeezed by the screw 7, at the moment, the liquid does not pass through the injection hose any more, zero-point scale marks are made on the scale rod 4 at the junction of the scale rod 4 and the opening of the first U-shaped groove 2, and the zero-point scale marks are zero points from the outermost end of the screw. And calculating the flow velocity corresponding to each prepared scale mark according to the recorded flow and time, and then making a specification, wherein the specification can check the flow velocity corresponding to each scale mark. In the using process of the controller, when the rotary cap 4 rotates to push the screw 7 to extrude the injection hose 5, the rotary cap 4 can push the scale rod 4 to enter the first U-shaped groove 2, the scale rod 4 extrudes the spring 3, and the scale rod 4 is always attached to the spiral cap 8 under the counter-acting force of the spring 3; after the graduated rod 4 is pushed forward, the corresponding graduated line can be read on the graduated rod 4 at the junction of the graduated rod 4 and the opening of the first U-shaped groove 2, and then the liquid dropping speed at the moment is searched according to the specification; the corresponding scale mark can be searched from the specification according to the speed requirement in the actual liquid dropping process, and the scale mark is adjusted in place in one step; the controller can accurately control the dropping rate.
