Abstract

The utility model discloses a flow controlled funnel which comprises a funnel body, a funnel pipe, a filtering net, a choke plug, a control rod and a control button, wherein the funnel body and the funnel pipe are in a horn shape of which the section is in an inverted trapezoid shape; the bottom of the funnel body and the top of the funnel pipe are connected into a whole; the meshed circular filtering net is movably fixed at the bottom of the funnel body; the control rod is a hollow round rod and penetrates through a through hole in the center of the filtering net and the funnel pipe; the cone frustum-shaped choke plug is fixed on the control rod; the control button is arranged on the outer surface of the funnel body and is connected with the upper end of the control rod through a digging line. The flow controlled funnel is simple in structure and convenient to use and can simultaneously realize backflow prevention, overflow prevention and flow control functions.

Description

A kind of flow controllable type funnel

Technical field

The utility model relates to a kind of funnel, is specially a kind of flow controllable type funnel.

Background technology

?with funnel, in container during perfusion fluid, when the air in container usually cannot be discharged smoothly, can drive the liquid in funnel upwards to reflux and even spill funnel, if fluid temperature is higher or band is corrosive, easily injure operator.When container is filled, the raffinate cognition in funnel is overflowed from bell mouth, causes waste.The better scheme that shortage addresses the above problem simultaneously at present.

Summary of the invention

The purpose of this utility model is to provide a kind of flow controllable type funnel with anti-overflow anti-return function.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of flow controllable type funnel, comprise infundibular body, funnelled pipe, filtering net, choke plug, control stalk and control button, infundibular body and funnelled pipe are the bell mouth shape that cross section is inverted trapezoidal, infundibular body bottom connects to one with funnelled pipe top, described filtering net is netted circle, filtering net is movably fixed to infundibular body bottom for filtering the liquid of pouring funnel into, and filtering net center has for wearing the through hole of control stalk; Control stalk is hollow round bar, control stalk through the through hole at filtering net center and funnelled pipe after its lower end stretch out funnelled pipe liquid outlet; Choke plug is inverted cone bench-type, and choke plug is fixed on the control stalk in funnelled pipe and can moves up and down with control stalk, for opening and blocking funnelled pipe liquid outlet; Control button is located at infundibular body outside face, and control button links the elevating control for choke plug by drag-line and control stalk upper end.

On described infundibular body, be carved with the scale graticule of mark liquid capacity.

The utility model, owing to adopting above-mentioned design, can be realized following beneficial effect: utilize the utility model in container during perfusion fluid, can filter liquid; Air in container can discharge in hollow control stalk; When container is filled liquid, press control button and make control stalk drive choke plug to move down to clog funnelled pipe liquid outlet, avoid the remaining liq in funnel to overflow.The utility model is simple in structure, easy to use, can realize funnel anti-return, anti-overflow and flow control function simultaneously.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the schematic diagram of filtering net.

In figure: 1 is infundibular body, 2 is funnelled pipe, and 3 is filtering net, and 4 is choke plug, and 5 is control stalk, and 6 is control button, and 7 is drag-line, and 8 is scale graticule.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model comprises infundibular body 1, funnelled pipe 2, filtering net 3, choke plug 4, control stalk 5 and control button 6, infundibular body 1 and funnelled pipe 2 are the bell mouth shape that cross section is inverted trapezoidal, infundibular body 1 bottom and funnelled pipe 2 tops connect to one, filtering net 3 is netted circle, filtering net 3 is movably fixed to infundibular body 1 bottom for filtering the liquid of pouring funnel into, and filtering net 3 centers have for wearing the through hole of control stalk 5; Control stalk 5 is hollow round bar, and control stalk 5 stretches out funnelled pipe 2 liquid outlets through through hole and rear its lower end of funnelled pipe 2 at filtering net 3 centers; Choke plug 4 is inverted cone bench-type, and choke plug 4 is fixed on the control stalk 5 in funnelled pipe 2 and can moves up and down with control stalk 5, for opening and blocking funnelled pipe 2 liquid outlets; Control button 6 is located at infundibular body 1 outside face, and control button 6 links the elevating control for choke plug 4 by drag-line 7 and control stalk 5 upper ends.

On infundibular body 1, be carved with the scale graticule of mark liquid capacity, be convenient to control the amount of perfusion fluid.

Utilize this device in container during perfusion fluid, filtering net 3 can filter liquid, and the air in container can discharge in hollow control stalk 5; When container is filled liquid, press control button 6 and make control stalk 5 drive choke plugs 4 to move down to clog funnelled pipe 2 liquid outlets, avoid the remaining liq in funnel to overflow.Also can first press control button 6 closing funnel pipe 2 liquid outlets, then reference mark graticule 8, to the liquid of pouring desired volume in funnel into, is then pressed control button 6 again and is opened funnelled pipe 2 liquid outlets, to quantitative perfusion fluid in container.
