Abstract

The utility model relates to an immediate display digital liquid flowmeter, comprising an axial flow chamber with an inlet and an outlet, an upper casing, an impeller, a worm, a worm wheel, the upper gear and the lower gear on a transmission counter and a disk face with a vertical display plate. The impeller drives the worm and the worm wheel, then drives the lower gear and the upper gear of the counter, and the upper drives the counter to rotate and displays digitals. The utility model has the advantages of small volume and high precision; the digitals can be correctly and directly read out through the utility model matching with a water conditioner; the time for replacing the filter material in the water conditioner can be known very easily, and people can drink safe and reliable purified water.

Description

The upright digital liquid flow meter that shows

The utility model relates to liquid flowmeter, particularly a kind of upright digital liquid flow meter that shows of vertical display digit.

The liquid flowmeter that uses generally adopts the pointer rotation mode at present, and shows that card is that horizontal positioned shows flow.Need during reading to read from the numeral of pointer indication, reading seems and comparatively bothers like this, and is easy to generate reading error.In addition, the flowmeter card of horizontal positioned is difficult to existing water purifier supporting, just can't know also therefore whether the filtering material in the water purifier needs to change after a period of time uses, and whether its filtering water is clean, has pollution-free.

In order to overcome above-mentioned weak point, the purpose of this utility model provides a kind of improved upright digital liquid flow meter that shows, the numeral of this flowmeter in can vertical demonstration card, straight reading dial, reading is correct rapidly, can also with the supporting use of existing water purifier, can very know easily when the filtering material in the water purifier needs to change, people can be drunk relievedly purify waste water reliably.

A kind of upright digital liquid flow meter that shows described in the utility model comprises the axial flow chamber of bringing mouth and outlet into, worm gear, worm screw, the gear sum counter, it also comprises upper shell, card with vertical display panel, promoted impeller by liquid, the transmission counting cogs and lower gear, the axial flow chamber is positioned at the bottom of flowmeter, be cylindrical shape, the left side of axial flow chamber is import, rear side is outlet, the indoor base that is equipped with of axial flow connects the taper apical axis, the apical axis upper end is equipped with worm screw and the impeller connecting shaft that tape spool holds, impeller is equipped with in the connecting shaft bottom, top is worm screw, the worm screw upper end places in the worm bearing, worm bearing is positioned at upper shell on projecting inward rear wall, the worm gear of doing radially transmission with worm screw rotates together with the worm gear connecting shaft, the worm gear connecting shaft flatly places on the upper shell interior antetheca and rear wall, the other end at the worm gear connecting shaft is equipped with transmission counting lower gear, the transmission counting that transmission counting lower gear is located on its top cogs and makes face of gear towards the engaged transmission that is 90 °, transmission counting cogs and is located in the upper shell connections that rotate of the supporting sleeve on the antetheca by it, and the transmission counting cogs and drives counter and rotate also display digit.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a kind of upright structural representation of facing that shows digital liquid flow meter.

Fig. 2 is the A-A cut-open view that Fig. 1 right side is looked.

Fig. 3 is the B-B cut-open view of the expression blade wheel structure looked of a left side, Fig. 1 bottom.

Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of upright digital liquid flow meter that shows comprises axial flow chamber 9, worm screw 23, worm gear 20, the gear sum counter 22 of bringing mouth 6 and outlet 7 into, it also comprises upper shell 16, card 1 with vertical display panel 21, by the impeller 10 that fluid promotes, transmission counting cogs 18 and lower gear 19.Axial flow chamber 9 is positioned at the bottom of flowmeter, be cylindrical shape, the left side of axial flow chamber 9 is a liquid-inlet 6, rear side is a liquid outlet 7, base is housed in the axial flow chamber 9 connects taper apical axis 11, apical axis 11 upper ends are equipped with the worm screw and the impeller connecting shaft 13 of band quartz glass bearing 12, and apical axis 11 contacts with bearing 12, and its friction factor is minimum.Impeller 10 is equipped with in connecting shaft 13 bottoms, and top is worm screw 23.Liquid enters from the import of axial flow chamber, promotes impeller and rotates together with worm screw, and liquid flows out from the outlet of axial flow chamber again.

Worm screw 23 upper ends place in the worm bearing 15, and worm bearing 15 is positioned at upper shell 16 on projecting inward rear wall 24.The worm gear 20 of doing radially transmission with worm screw 23 rotates together with worm gear connecting shaft 14.Worm gear connecting shaft 14 flatly places upper shell 16 interior on projecting inward antetheca 25 and rear wall 24.Worm screw 23 drives worm gear 20 and rotates.

At the other end of worm gear connecting shaft 14 transmission counting lower gear 19 is housed, the transmission counting that transmission counting lower gear 19 is located on its top cogs and 18 makes face of gear towards the engaged transmission that is 90 °.Transmission counting cogs and axles is housed in the middle of 18, and this is installed in the upper shell 16 in the supporting sleeve 17 on the antethecas 25, and the transmission counting cogs 18 together with this axle rotation.On transmission counting cogs 18 axle counter 22 is housed, the transmission counting cogs and 18 drives counters 22 and rotate, and by vertical display panel 21 display digits that are stained with transparent panel.When transmission counting lower gear 19 rotated a circle, the transmission counting cogged 18 and rotates a tooth, and the transmission counting cogs and 18 revolves with 1: 32 transmission speed ratio and to turn around.Counter 22 on the connecting shaft is 10 systems, and when transmission counting lower gear 19 rotated a circle, the units of counter then stirred little lattice, stirs carry to seniority sequentially with this.

The packing washer 8 that can prevent fluid seepage is equipped with in the junction of upper shell coaxial flow chambers 9 16, and fixedly connected by screw 5.

Upper shell 16 is equipped with the gasket seal 4 of waterproof with the junction of display panel 21 card face frames 2, and fixedly connected by screw 3.Whole card 1 protrudes in outside the face frame 2.

Worm screw in the utility model, worm gear, the transmission counting cogs and lower gear is made by the less nylon material of friction factor, can anticorrosion, can improve transmission accuracy again.

Upright apparent digital liquid flow meter volume described in the utility model is little, precision is high, with the supporting use of water purifier, just can correctly read to know the water purification total amount, in time change the filtering material in the water purifier, people can be drunk by water purifier relievedly purify waste water reliably.The utility model also can be used for doing in medicine, the chemical industry fluid flow counting.
