Abstract

The utility model discloses a direct type impeller meter, which includes a metal shell (1), an inlet (2) arranged on the metal shell (1), an outlet (3), a rotating shaft (4) and a rotary wheel (5) fixed in the metal shell (1), magnetization elastic wheel (6) fixed on the rotary wheel (5) and sliding connected to the inner wall of the metal shell (1), and a separate plate (7) connected to the inner wall of the metal shell (1) separating the inlet (2) and outlet (3). A gap (8) exists between the separate plate (7) and the out wall of the rotary wheel (5). The utility model mainly uses the metal shell, magnetization elastic wheel, and the separate plate to realize the elastic and magnetic seal. The running wheel always keeps sliding contacting to the inner wall of the metal shell, which can close the gap, avoid the wearing clearance, reduce the leakage, and improve the measurement precision. The utility model can directly measure the real volume of the flowing liquid passing by and can measure any flow rate without changing the value, and has a strong generality. The utility model also has a simple structure, low cost, small volume, wide range, low error, and steady performance.

Description

Direct-type impeller gauging table

Technical field:

The utility model relates to a kind of gas or level meter scale, the direct-type impeller gauging table of especially a kind of simple in structure, with low cost, dependable performance, accurate measurement.

Background technology:

At present, known direct-type gas meter has following two kinds basically: a kind of is the Roots's table that is applied to industrial large capacity meter amount, and also having a kind of is the epithelium formula gas meter, flow meter that generally uses.Roots's meter accuracy requires high, easily loses efficacy because of impurity stops up, and generally need add device for filtering impurities, and complex structure, volume is big and heavy, need take bigger space when not only installing, and manufacturing cost, installation cost are all bigger; Epithelium formula gas meter, flow meter is made up of reciprocating members such as two groups of four-bar mechanisms, pistons, slow movement not only, and need a large amount of special toolings and mould to produce, and complex manufacturing, volume is big, cost is high.

Summary of the invention:

The utility model is in order to solve existing in prior technology the problems referred to above, and the direct-type impeller gauging table of a kind of simple in structure, with low cost, dependable performance, accurate measurement is provided.

Technical solution of the present utility model is: a kind of direct-type impeller gauging table, metal shell 1 is arranged, on metal shell 1, be provided with import 2, outlet 3, metal shell 1 internal fixation has rotating shaft 4 and runner 5, be connected to the magnetization spring leaf 6 that slides and join with metal shell 1 inwall with runner 5 stationary phase, be connected to the dividing plate 7 of at interval import 2, outlet 3 with metal shell 1 inwall, between dividing plate 7 and runner 5 outer walls gapped 8.

Be provided with blade casting die 9 in the place ahead in described gap 7.

Described blade casting die 9 is pressure rollers.

Described pressure roller places in the support 10 that is connected as a single entity with dividing plate 7.

Inwall at metal shell 1 is connected to antifriction layer 11.

The utility model mainly is to utilize magnetization spring leaf and dividing plate to carry out resilient seal, be aided with formed magnetic seal between housing and magnetization spring leaf, blade in the motion all the time with the sliding contact of metal shell inwall, thereby but closing gap and avoid the generation of wearing clearance reduces and leaks, improves measuring accuracy; Can directly measure the fluid actual volume that is flow through, not need variate, small-large flow is all measurable, highly versatile, have simple in structure, cost is low, volume is little and range is big, error is little, steady performance.

Description of drawings:

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

Embodiment:

Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of direct-type impeller gauging table, it is circular metal shell 1 that the cross section is arranged, can be at metallized metal housing 1 liner one deck plastics antifriction layer 11.On metal shell 1, be provided with import 2, outlet 3, import 2, outlet 3 in the same way, incorgruously all can.Rotating shaft 4 is arranged and be enclosed within runner 5 in the rotating shaft 4 at metal shell 1 internal fixation, with runner 5 fixed bondings magnetization spring leaf 6 is arranged, magnetization spring leaf 6 can be made with the plastics that are added with magnetic, its length should guarantee to join with the slip of metal shell 1 inwall in runner 5 rotation processes, fixedly be connected to the dividing plate 7 of at interval import 2, outlet 3 with metal shell 1 inwall, between dividing plate 7 and runner 4 outer walls gapped 8.Resistance when passing through gap 8 in order to reduce magnetization spring leaf 6, can be provided with blade casting die 9 in the place ahead (the place aheads on magnetization spring leaf 6 direction of motion) in gap 8, can be pressing plate or pressure roller etc., preferably pressure roller can place pressure roller in the support 10 that is connected as a single entity with dividing plate 6.

The course of work:

Gas or liquid enter in the metal shell 1 from import 2, under the pressure of gas or liquid promotes, magnetization spring leaf 6 drives runner 5 and 4 rotates around the shaft, when below forwarding blade casting die 9 to, blade casting die 9 will magnetize spring leaf 6 to be overwhelmed, overwhelm that magnetization spring leaf 6 after (closing up) is rotated further with runner 5 and the gap 8 by dividing plate 6 belows, flick subsequently, the inwall and another gas or the liquid that magnetizes between the spring leaf 6 that are closed in dividing plate 7, metal shell 1 are then discharged from exporting 3; Flicking and closing up in proper order and carry out of magnetization spring leaf 6 also drives runner 5 simultaneously and rotates continuously, and rotating shaft 4 passes to the cummulative metering number that counter demonstrates gas or liquid, can realize the direct volumetric metering of gas or liquid.
