Accompanying drawing explanation
Fig. 1 is this antifreeze decompression water meter overall structure schematic diagram.
Fig. 2 is water flow measurement principle schematic.
Detailed description of the invention
Below in conjunction with accompanying drawing, as embodiment, scheme is further illustrated.
With reference to Fig. 1,2, with water-stop sheet 22 as separate layer, lower section is the part that current pass through, and mainly by impeller cavity 15, magnetic valve and check-valves are constituted, and are provided with impeller 14 by lower rotary shaft 31 impeller storehouse 15 in, is used for taking the amount of current process.Seal with antifreeze piston ring 11 in the lower section in impeller storehouse and can the separation mode of sliding up and down, form an antifreeze spring cavity 13a, equipped with antifreeze spring 13 in antifreeze spring cavity, when the chance freezing of water in impeller cavity is expanded, impeller cavity 15 moves down, be pressed down against by antifreeze spring 13 through antifreeze piston ring 11, i.e. the space of impeller cavity 15 becomes big, bursts water meter without swollen evil idea.The centre of going to the bottom of antifreeze spring cavity 13a has antifreeze air vent 12, when being to move down for impeller cavity 15, gets rid of the air that spring cavity 13a is, makes impeller cavity descending smoothly.Impeller cavity 15 surrounding is respectively arranged with filter screen 16, prevents slag thing in water from affecting impeller in entering impeller cavity and normally works.
Lower rotor part 32 is fixed on the top of lower rotary shaft 31, and lower rotor part 32 is fixedly mounted with lower magnet ring 24a around axle above.In the spindle nose corresponding position of water-stop sheet upper and lower surface Yu upper and lower rotating shaft, it is fabricated to the arc nest of indent, makes the spindle nose of two rotating shafts stretch in nest, but do not contact, as lower rotary shaft 31 and the Blind locating holes of upper rotating shaft 33.Upper rotor part 25 is fixed at the middle part of upper rotating shaft 33, fixes upper magnetic ring 24b around axle below upper rotor part 25, and the top of upper rotating shaft 33 is fixedly mounted with hydrodynamic(al) gear 26, and hydrodynamic(al) gear 26 is ratcheting with the counter gear 27 of its side.Fix with the axle of enumerator 1 at the axis hole of counter gear 27 and be connected.Magnet ring on upper and lower rotor is permanent magnet.
Making in the left side of impeller cavity 15 and have magnetic valve 19 and check-valves 17, wherein magnetic valve is against impeller cavity, and the two is connected.Have in magnetic valve 19 and be in the upper valve plug 23 of the upper and lower both sides of water-stop sheet 22 and lower valve plug 21, after the water yield that user is predetermined is finished, by the control of enumerator, pull open the distance of upper and lower valve plug, lower valve plug 21 falls, block current, user's water is truncated, after again have subscribed to water consumption by enumerator, lower valve plug 21 just returns to open position, attracting with upper valve plug 23, and location absorption is on water-stop sheet 22 upper and lower surfaces, magnetic valve 19 is i.e. held open state until subscribing the water yield and being finished, and is just re-closing off.
Check-valves 17 is made at the water export of water meter, i.e. user's water end (W.E.), and valve chamber is cylindrical, and under normal circumstances, valve ball 18 floats, and current flow out smoothly；When there are reverse current in pipeline, valve ball 18 falls, and blocks valve port, and the water of reverse flow can not enter water meter, plays non-return effect.
Decompression part is made at the water inlet 7 of water meter, it is by discoidal valve block 10, it is fixed in the pull bar 8 of valve block 10 top edge apex, the upper end of pull bar 8 is affixed with pressure-reducing piston ring 5, pressure-reducing piston ring 5 is in the bottom in relief spring chamber, activity is placed on the block that sidewall bottom relief spring chamber protrudes, and uses three such blocks, being distributed in bottom relief spring chamber on sidewall on the loop line in same level face of interval equalization.Pressure-reducing piston ring 5 contacts with columnar relief spring cavity wall tight fit by the elastic colloid sealing ring on its sidewall；Pull bar 8 below pressure-reducing piston ring 5 upper side central point, an affixed slide bar vertically upward, this slide bar and pressure-reducing piston ring 5 is on same vertical line；Relief spring 2 is enclosed within this slide bar, and its lower end is affixed with pressure-reducing piston ring 5；Through hole is arranged at the top in relief spring chamber, it is easy to discharge gas in chamber, resistance when moving on piston, meanwhile, stretches out slide bar upper end above relief spring 2, a hexagonal (hexagon)nut is installed at top, i.e. may utilize and play the part of hand-held tool, under stretching from the through hole of relief spring top of chamber, pull and move on slide bar, thus valve block 10 is risen to the position of the part current cutting off inlet pipes, reach the purpose that reduces pressure.
If reduced pressure without manual mode, then when in pipeline, hydraulic pressure is big, hydraulic pressure pushes upper shifting to pressure-reducing piston ring 5, and relief spring 2 shrinks, and pull bar 8 band moving valve plate 10 moves, and the cross section of water inlet 7 is blocked a part, and in water meter, hydraulic pressure just reduces.Valve block 10 is when water inlet is shown in a fully open operation, and it is suspended in a clip slot adjacent with antifreeze spring cavity 13a position.
In the float cavity of side, relief spring chamber, place the float-controlled valve 4 of an elongated ampuliform, have the base plate preventing float from dropping bottom float cavity, in the middle of this base plate, drive the mouth of a river into, by water inlet, make float cavity be integrated with the chamber in water meter.Pressure QI KOU 3 is reduced at float cavity top, and this mouthful can accommodate the nipple plug on long bottle shape plastic float top.At ordinary times, when float cavity middle water level is low, decompression exhaust mouth 3 gas in opening, water meter is discharged from decompression exhaust mouth 3, and when water level is big, water level is high, float-controlled valve 4 moves, is closed by decompression exhaust mouth 3.Adding the thrust moved on pressure-reducing piston ring 5, the power that pull bar 8 band moving valve plate 10 moves also increases.
Antifreeze piston ring 11 and pressure-reducing piston ring 5 are all made with rustless metal material, and making on the side of piston ring has seal groove, equipped with rubber mass elastic seal ring in groove.
Outside the housing of 75-1 type enumerator used, install one stir control piece 28 and the zero shift fork 29 that counting tooth resets and subscribes water consumption, at the shell 9 of water meter, one Subscriber Application Barring Lock 30 is set with the connecting portion of upper cover；Water-stop sheet 22 is above without pool, the following is water flow spaces, and watermeter shell 9 is also divided into upper and lower two halves, in the junction of upper and lower two halves by a Joining clasp 6, by upper and lower two halves, is fastened into a watermeter shell 9.
The antifreeze decompression water meter made in the manner described above, water enters in water meter from water inlet 7, the streamline water inlet measuring the water yield is flowed out in impeller cavity 15, it is folded to magnetic valve 19 inner chamber top, turn back downwards after streamline outlet 20, from magnetic valve 19 end opening out, flow through check-valves 17, enter in the use water lines of user.After winter water meter freezing and expansion, because of the effect of antifreeze spring 13, make the water meter inner chamber of expansion, have the space moved down, thus do not burst.When hydraulic pressure is big in supply line, push pressure-reducing piston ring 5, promote and move on relief spring, extract valve block 10, reduce inflow in water meter, reduce the hydraulic pressure in water meter.The existing procucts that the water meter counter employing multiple counting of 7-11 type is wheeled, subscribe mode to playback zeroing and water consumption, solve the water supply department problem of management to user's water, after the reservation water yield is finished, utilize Magnetic valves, and water meter turns off current voluntarily；Utilize the effect of check-valves 17, cut off reverse flow, it is to avoid the reversing of water meter turbine.
