Description
Technical field
The utility model relates to a kind of flowmeter, particularly the spinner-type flowmeter that from up to down flows of a kind of medium.
Background technology
Spinner-type flowmeter, also known as suspended body flowmeter, is the one of variable area formula flowmeter, and it to be placed in tapered tube can the rotor (also claiming float) of freely up and down movement to be formed by a tapered tube and one.Spinner-type flowmeter body can be connected with measuring channel with two end flanges, screw thread or flexible pipe, is vertically mounted on measuring channel.When fluid flows into Taper Pipe from bottom to top, dammed by rotor, pressure differential is produced like this between rotor upstream and downstream, rotor rises under the effect of pressure differential, and at this moment acting on epitrochanterian power has three: fluid is to the gravity (downwards) of the dynamic pressure (upwards) of rotor, rotor buoyancy in a fluid (upwards) and rotor self.During flowmeter at right angle setting, rotor c.g. and Taper Pipe tubular axis can coincide, and act on epitrochanterian three power and are all parallel to tubular axis.When these three power reach balance, rotor just to float in Taper Pipe on a certain position reposefully.Now, gravity=dynamic pressure+buoyancy.For given spinner-type flowmeter, rotor size and shape oneself through determining, therefore its buoyancy in a fluid and self gravitation are all known constants, have fluid only and change the size of the dynamic pressure of float with incoming flow flow velocity.Therefore when incoming flow flow velocity becomes large or when diminishing, rotor will do movement up or down, and the flow cross-sectional area of relevant position also changes, until speed corresponding when flow velocity becomes balance, rotor is just stablized on new position.For a given spinner-type flowmeter, the size that the position of rotor in Taper Pipe and fluid flow through the flow of Taper Pipe becomes one-to-one relationship.The measuring principle of Here it is rotor stream child meter.
According to the principle of spinner-type flowmeter, spinner-type flowmeter usually can only at right angle setting, and medium can only be bottom-up by spinner-type flowmeter, so just constrains the scope of application of spinner-type flowmeter.
Summary of the invention
The utility model is the problem that can only affect usable range for spinner-type flowmeter medium from bottom to top, propose the spinner-type flowmeter that a kind of medium from up to down flows, make it can meet medium from up to down by spinner-type flowmeter, easy to use, do not need other utility appliance during test.
The technical solution of the utility model is: the spinner-type flowmeter that a kind of medium from up to down flows, and the measuring tube of spinner-type flowmeter is vertically placed, and the flow passage structure of spinner-type flowmeter comprises influent stream pipe, recirculatory pipe, influent stream box, backflow box,
Recirculatory pipe is vertically parallel with measuring tube measuring channel, and recirculatory pipe top arranges a flow channel entry point, is the cavity of recirculatory pipe under flow channel entry point, cavity and flow channel entry point obstructed, cavity bottom arranges a runner exit;
The straight tube of influent stream Guan Youyi root column type and an elbow pipe welding composition L-type structure, the vertical entrance in one, influent stream pipe upper end, there are two orthogonal openings lower end, straight tube is vertically parallel with recirculatory pipe, the vertical entrance in straight tube upper end docks with the flow channel entry point of recirculatory pipe, and influent stream pipe bend pipe lower end taps into the hand-hole of stream box;
Influent stream box top is offered and is portalled, and docks with measuring tube lower port;
Right side above measuring tube conical section has measuring tube to portal, and measuring tube portals and is connected on the left side open butt joint of the backflow box in the middle of measuring tube and recirculatory pipe with parallel spanning, and the right openings of backflow box is docked with upper opening on the left of recirculatory pipe;
Medium portals through the vertical entrance of influent stream pipe, influent stream pipe bend pipe, influent stream box, measuring tube lower port, measuring tube successively from recirculatory pipe entrance, the box that refluxes, recirculatory pipe, recirculatory pipe runner exit flow out.
Described recirculatory pipe runner inlet axis and runner exit axis collinear.
The top of described measuring tube arranges a capping.
The beneficial effects of the utility model are: the spinner-type flowmeter that the utility model medium from up to down flows, and increase flow passage structure, medium can enter from above, easy to use, does not need other utility appliance during test.
Accompanying drawing explanation
Fig. 1 is the spinner-type flowmeter structural representation that the utility model medium from up to down flows.
Embodiment
The spinner-type flowmeter structural representation that from up to down flows of medium as shown in Figure 1, measuring tube 6 is common rotor flowmeter structure, the flow passage structure of spinner-type flowmeter: recirculatory pipe 3 is vertically parallel with measuring tube 6 measuring channel, recirculatory pipe 3 top arranges a flow channel entry point 1, entrance is for 1 time the cavity of recirculatory pipe 3, cavity and entrance 1 obstructed, cavity bottom arranges a runner exit 4, influent stream pipe 2 forms L-type structure by the straight tube of a column type and a bend pipe, the vertical entrance in one, upper end, straight tube is vertically parallel with recirculatory pipe 3, on straight tube, end entrance docks with flow channel entry point 1, bend pipe lower end below tapping on the left of recirculatory pipe 3 passes, straight tube and bend pipe junction are welded airtight, a hole is offered on the right side of influent stream box 5, dock with influent stream pipe 2 bend pipe lower end, a hole is offered on influent stream box 5 top, dock with measuring tube 6 end opening, measuring tube 6 is vertically placed, a hole is offered on the right side of measuring tube 6, the left side open butt joint of the backflow box 7 in the middle of measuring tube 6 and recirculatory pipe 3 is connected on parallel spanning, the right openings of backflow box 7 is docked with upper opening on the left of recirculatory pipe 3.
