Description

Interrupted flow meter

The utility model relates to a kind of metering outfit that is used for liquid meter.

The metering outfit that is used for the liquid meter aspect at present is more, common have water meter, electromagnetic flowmeter, worm gear flowmeter, a ultrasonic flow meter, these liquid flow mearuement equipment all are can only the flow of metering liquid under the continuous flow state, can not the flow of metering liquid under discontinuous mobile state.

The purpose of this utility model provides a kind of metering outfit that can the fluid flow of metering liquid under discontinuous mobile state.

The utility model realizes that the above-mentioned purpose technical solution is, a top be garden tubular (or square), upper end be equipped with liquid inlet duct, upper lateral part be equipped with run-down pipe, bottom be taper, lower end be opening, and within it portion the reservoir vessel of solenoid valve and fixing top of volume size are housed is that garden tubular (or square), bottom are that taper, lower end are that the measuring container of opening is connected together, be fixed on the support.The connection axostylus axostyle that is connected with the solenoid valve central shaft is housed in measuring container and be contained in the taper that connects on the axostylus axostyle that valve following valve stifled and biconial (or spherical) is stifled, magnetic float, floater guiding bar (or floater guiding pipe), near the float position tongue tube pillar is being housed, tongue tube (or photoelectric tube or magnetic induction part) is housed in the tongue tube pillar, and the liquid in tongue tube and the measuring container is separated, also be connected with solenoid valve, electronic counter (being electronics totalizer or the counter that removes automatic shutdown function) with lead by terminal box (electromagnetic switch).Central shaft on the opening of the opening of reservoir vessel lower end, measuring container lower end and the solenoid valve be connected the solenoid valve central shaft on be connected axostylus axostyle and be contained in that valve following valve stifled and biconial (or spherical) gets lodged on the same center line in the taper that connects on the axostylus axostyle, the opening of reservoir vessel lower end is the conical surface that tubular lower end, garden has gradually expanded form, on its conical surface O-ring seals is housed; The opening of measuring container lower end is that the garden tubular is stained with the rubber washer with bore in the top.When on the solenoid valve central shaft drive to connect axostylus axostyle, moving, make valve stifled can close store the opening that holds end, valve blocks up and can open the opening of measuring container lower end simultaneously down; When the solenoid valve central shaft drive to connect axostylus axostyle and moves down, last valve is stifled can open the opening of reservoir vessel lower end, valve is stifled down can close the opening that metering holds end simultaneously, finished simultaneously that open a pass one or the action of one open-one close.

The utility model is owing to take abovementioned technology, and compared with prior art, difference is: (1) the utility model has the mechanism that can measure the fluid flow under the discontinuous mobile state; (2) opening of the opening of reservoir vessel lower end, measuring container lower end, solenoid valve central shaft and be connected connection axostylus axostyle on the solenoid valve central shaft all on same center line, being contained in that the stifled and following valve of the last valve that connects on the axostylus axostyle blocks up is to finish simultaneously that open a pass one or the action of one open-one close; (3) indicate liquid level high and low position (i.e. the volume between liquid level and the following liquid level is gone up in indication) with the fixing measuring container of volume size by dress magnetic float within it, utilize magnetic float to cooperate with tongue tube (or photoelectric tube or magnetic induction part), control electromagnetic valve opens and closes, and solenoid valve is whenever left once discharge fixing (design) flow value; Utilize magnetic float to cooperate with tongue tube (or photoelectric tube or magnetic induction part), electronic counter, make solenoid valve whenever open the fixed flow value of once discharging and enter electronic counter once, the fixed flow value of realizing adding up measures.

Below in conjunction with a specific embodiment in accompanying drawing detailed description the utility model.Present embodiment is an interrupted flow meter that is used to measure sewage.

Accompanying drawing is the structural representation of interrupted flow meter.

This meter comprises that a top is that garden tubular, bottom are the reservoir vessels 1 of taper, in reservoir vessel 1 upper end liquid inlet duct 20 is housed, upper lateral part is equipped with overflow outlet 21, be connected with run-down pipe 24 through elbow 23, solenoid valve 3 is housed in reservoir vessel 1, by solenoid valve seat 2 usefulness screws 4 and screw 5 solenoid valve 3 is fixed on the reservoir vessel 1, it is the opening 8 that tubular lower end, garden has the gradually expanded form conical surface that top is equipped with in reservoir vessel 1 lower end, on the gradually expanded form conical surface of opening 8, O RunddichtringO 6 is housed, opening 8 is connected on the measuring container 25 with screw 22.The connection axostylus axostyle 7 that is connected with solenoid valve 3 central shafts is housed in measuring container 25 and is contained in the taper that connects on the axostylus axostyle 7 valve stifled 9 and biconial (or spherical) valve stifled 26 down, floater guiding bar 10, on floater guiding bar 10, be with magnetic float 11, at position tongue tube pillar 13 is housed near magnetic float 11, tongue tube 12 and tongue tube 14 are housed in tongue tube pillar 13, and the liquid in tongue tube 12, tongue tube 14 and the measuring container 25 is separated, be connected with solenoid valve 3, electronic counter 17 with lead 19 and logical terminal boxes 18.Floater guiding bar 10 and tongue tube pillar 13 usefulness step disks 15 are fixed in the measuring container 25.The opening 28 of garden tubular is equipped with in measuring container 25 lower ends, is stained with the rubber washer 27 with bore on opening 28.Connect axostylus axostyle 7 and be contained in the last valve stifled 9 that connects on the axostylus axostyle 7 and following valve block up 26 and the opening 28 of the opening 8 of reservoir vessel 1 lower end, measuring container 25 lower ends on same center line.Reservoir vessel 1 and measuring container 25 are fixed on the support 16.Reservoir vessel 1 and measuring container 25 can be made with stainless steel, steel plate, plastics.
