Pipe passage 33, the idler wheel have idler wheel axis body (not shown), and having in the pipe clamp makes the axis body that can slide wherein
Idler wheel slideway 34, when the idler wheel slides in roller channel, by with pipe clamp define the pipe passage 33 and with rolling
Opposite side wall cooperation extruding pipeline is taken turns to be provided at least on idler wheel slideway 34 to adjust the fluid flow in pipeline
One roller shaft body can be slidably therein limiting groove 35；In slider roller to change the flow section of pipeline, and then realize
When the folding of pipeline, closing and flow-rate adjustment, due to being provided with limiting groove 35 on idler wheel slideway 34, work as roller-coaster
When to the limiting groove 35, axis body can slide into the limiting groove 35, to user with feel, no longer need in observation pipeline
Depending on the flow condition of liquid.Improve the simple and convenient and safe of folding, closing and the flow-rate adjustment operation of drain pipe pipeline
Reliability.
Further, the idler wheel slideway 34 and the pipe clamp to define the side wall of idler wheel slideway 34 parallel, it is described
Limiting groove 35 is multiple, corresponding to the limiting groove 35 on the side wall for defining idler wheel slideway 34 of the pipe clamp
The first different protrusion 36 of height is equipped at position；Idler wheel slideway 34 passes through the direction of pipe clamp to extend along pipeline.Work as rolling in this way
When wheel axis body slides in idler wheel slideway 34, the side wall cooperation opposite with idler wheel, defining pipe passage 33 of idler wheel and pipe clamp,
By the different degrees of extruding to the pipeline between the side wall and idler wheel, folding and the flow-rate adjustment of pipeline are realized.
The roller channel 34 walks direction along pipeline and is equipped with multiple limiting grooves 35.When to slide into the limit recessed for idler wheel axis body
When slot 35, the instruction of corresponding discharge is provided.How exemplary description is realized that flow indicates below.
As can be seen that the idler wheel slideway 34 and the idler wheel that defines of the pipe clamp are slided in schematic cross-sectional view shown in Fig. 5
The side wall in road is mutually inclined, to idler wheel slided along roller channel 34 when (such as never squeeze pipeline one end towards
The other end), the side wall cooperation of idler wheel and roller clip gradually squeezes pipeline, and to reduce the sectional area of pipeline, limitation passes through
The fluid flow of pipeline.When the axis body of idler wheel 32 slides into limiting groove 35, axis body slides into the limiting groove 35, and gives
User is with stronger feel.The axial section of the limiting groove 35 for example could be provided as arc-shaped, facilitate slide-in and cunning
While going out, the feel of user is further enhanced, and then improves its convenience and security reliability.Idler wheel 32 is in sliding process

There are three limiting grooves 35 for setting.Can certainly limiting groove 35 be set in 1/3 flow, 1/4 flow etc., therefore can root
The groove of instruction corresponding discharge is set according to actual needs.
As can be seen that idler wheel slideway 34 and institute in the schematic cross-sectional view of another embodiment of the utility model shown in Fig. 6
The side wall for defining idler wheel slideway for stating pipe clamp is parallel, while in correspondence on the side wall for defining the idler wheel slideway 34 of pipe clamp
The first protrusion 36 is equipped at the position of the limiting groove 35, it is recessed that the height of the first protrusion 36 could be provided as and slide into limit
Idler wheel cooperation in slot 35 squeezes pipeline so that fluid flow is respectively maximum stream flow, 1/2 flow and zero delivery.When idler wheel 32
Axis body when sliding into limiting groove 35, in the distinguishable slide-in limiting groove of axis body 35, to user with feel, idler wheel 32 exists
The distance between outer and first protrusion 36 changes the cross-sectional flow area of pipeline outside its in sliding process.It can certainly be 1/3
Flow, 1/4 flow etc. are arranged limiting groove 35 and the first protrusion 36, at the same the quantity of groove 35 and the first protrusion 36 nor
It is fixed, and can be set as needed with use condition.
In the embodiment shown in fig. 7, other features are identical with above-described embodiment, the difference is that limiting groove 35
Axial section be set as rectangle, while conveniently sliding in and out also give user with stronger feel.
Further, the side wall for defining idler wheel slideway of the idler wheel slideway and the pipe clamp is mutually inclined.
Further, the limiting groove is three.
Further, the axial section of the limiting groove is arc-shaped.
Further, the axial section of the limiting groove is arc-shaped.
Further, the axial section of the limiting groove is rectangle.
Further, the axial section of the limiting groove is rectangle.
Above is only the preferred embodiment of the utility model, cannot limit the power of the utility model with this certainly
Sharp range, therefore equivalence changes made according to the patent scope of the utility model, still belong to the scope of protection of the utility model.
