Description
Technical field
The utility model relates to the liquid feed device in a kind of water conservancy project field, particularly relates to the constant current liquid feed device that a kind of adjustable constant liquid supply pressure combines with the cutoff port free discharge.
Background technology
In scientific research and production,, often need provide uniform and stable fluid flow for to reach certain specific purpose.At present, the technology that adopts usually has measuring pump or adopt flow stabilization apparatus etc. in the feed flow pipeline.The former is under external force drives, and by plunger or the isopyknic reciprocal variation of barrier film, can regulate flow in a big way, realizes providing the constant flow rate of degree of precision, but apparatus expensive.In the feed flow pipeline, adopt flow stabilization apparatus be by pipeline in the variation of pressure or flow, make the elastic element distortion in the device, thereby the trend that flow increases in the pipeline is eased.But this flow stabilization apparatus can only work under the bigger condition of liquid supply pressure and flow, and can only maintain increasing flow and set near the flow, and precision is also lower.
Summary of the invention
The purpose of this utility model provides a kind of constant current liquid feed device that can realize the accurate constant current feed flow.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of constant current liquid feed device is characterized in that, comprising: bottle 2, the blow point adjusting flexible pipe 9 that is connected in bottle 2 bottoms one end and the throttle mechanism that is connected in the other end; Described bottle top has spout 1; Described blow point is regulated flexible pipe and throttle mechanism is communicated with bottle.
Described throttle mechanism comprises: throttling sheet 4, liquid outtake chamber 7; Has cutoff port 5 on the described throttling sheet; Described throttling sheet is stuck in the passage that is communicated with bottle and liquid outtake chamber by pad 3, and described throttling sheet can be replaced by other throttling sheet that cutoff port varies in size; The top of described liquid outtake chamber has air extractor vent 6, the bottom is communicated with head piece 8.
The bottle wall of described bottle is provided with scale 10, to the bottle top, is used to cooperate blow point to regulate flexible pipe 9 and accurately regulates the blow point height at the bottom of the bottle.
Compared with prior art, the beneficial effects of the utility model are: (1) by regulating the Ma Shi bottle blow point and adopt suitable cutoff port, can realize high precision, stable constant current feed flow under small flow, its flow adjustment range is big, regulates simple and convenient; (2) equipment does not need extra power, and energy savings is with low cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by specific embodiment.
As Figure 1-1, a kind of constant current liquid feed device comprises: bottle 2, the blow point adjusting flexible pipe 9 that is connected in bottle 2 bottoms one end and the throttle mechanism that is connected in the other end; Described bottle top has spout 1; Described blow point is regulated flexible pipe and throttle mechanism is communicated with bottle; The bottle wall of described bottle is provided with scale 10, to the bottle top, is used to cooperate blow point to regulate flexible pipe 9 and accurately regulates the blow point height at the bottom of the bottle.
Shown in Fig. 1-2, described throttle mechanism comprises: throttling sheet 4, liquid outtake chamber 7; Has cutoff port 5 on the described throttling sheet; Described throttling sheet is stuck in the passage that is communicated with bottle and liquid outtake chamber by pad 3, and described throttling sheet can be replaced by other throttling sheet that cutoff port varies in size; The top of described liquid outtake chamber has air extractor vent 6, the bottom is communicated with head piece 8.
Constant current liquid feed device of the present utility model is a propulsive effort with gravity, can set the feed flow flow accurately by regulating driving liquid level and throttle unit.
Working process of the present utility model is that device is filled with Ma Shi bottle 2 by Ma Shi bottle spout 1 with liquid, with spout 1 sealing; Cooperate blow point to regulate the blow point that flexible pipe 9 is set the Ma Shi bottle by scale 10, at this moment, the constant current liquid feed device will obtain stable driving liquid level; The cutoff port 5 of liquid in the device on throttling sheet 4 flows into liquid outtake chamber 7, finally leaves the constant current liquid feed device by going out head piece 8.Cutoff port 5 on the throttling sheet 4 and air extractor vent 6 assurance devices in the liquid outtake chamber are realized the cutoff port free discharge, and this mechanism and above-mentioned stabilized driving liquid level synergy obtain the accurate constant current source.By regulating the position and the throttling hole size of blow point, can regulate the flow of the utility model constant current liquid feed device easily.
It should be noted last that, above embodiment is only unrestricted in order to the explanation technical solutions of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
