Abstract

The utility model relates to an improved household dry type two-way tap water meter. On the basis of a dry type water meter of the Germany, after the inner pore diameter of a water outlet is enlarged, a water outlet pore canal and a water inlet pore canal are processed into the pore canals which are parallel to each other. The improved water meter has double function. A water inlet and a water outlet can be exchanged freely, and the actual water consumption can be accurately recorded on a direct reading disk of the water meter. The utility model overcomes the defects of the original water meter of difficult reading because of unreasonable structure or reversed reading of the water meter because the water outlet and the water inlet are arranged in opposite direction. The utility model can effectively prevent users from stealing water. The utility model has the advantages of small size, light weight, beautiful appearance, simple installation, clear reading, and wide popularization prospect.

Description

Novel two-way water meter

The utility model belongs to a kind of two-way tap water meter of dry type that is used for family's water consumption metering of improvement type.

The tap water metering water meter that extensively adopts is mechanical wet type vane wheel water meter at present, in use can play certain metering effect, but because structure is unreasonable, directly reading often because of incrustation scale pollutes dial plate, is not often allowed the consumption of the accurate water of readability.As the phenomenon of water steathily also can be appearred in water meter water delivering orifice and the anti-dress of water inlet.Therefore, country has determined to forbid to continue to use, and another is introduced the single current dry-type meter and has begun to adopt at home, this water meter can direct-reading, water flows into water meter by the inlet opening during use, makes the impeller rotation, by the magnetic drives of magnet ring above the impeller, central gear and impeller are rotated synchronously, through gearing mesh, drive gear on worm again, be delivered to first character wheel again, drive the transmission of eight bit word wheel by seven decimal idle wheels, thereby write down out the total amount of the water of the water meter of flowing through.But this kind water meter causes the machine of water steathily can for uncivil user owing on the structural design, after water meter water inlet and water delivering orifice are exchanged installation, will make counter become the counter-rotating operation by just transporting row.

The purpose of this utility model is the dry-type meter that design for the drawback that overcomes above-mentioned two kinds of water meters a kind of can direct-reading and anti-dial plate pollutes and water meter reverses.

The implementation method of this utility model is:

This two-way water meter is the improvement to former German dry-type meter, make it to meet the standard of China's tap water water meter, because the dry-type meter of Germany just, all makes water meter turbine rotate, cause the numeral of water meter counter to increase or reduce, this obviously is worthless, the reason that this situation occurs is due to the center line of exhalant canal and intake tunnel intersects, and that is to say that into the current in water duct flow into the total amount that water meter revolves record water along impeller rotation promotion impeller; If the duct to road, furnishing inlet opening, can be made the impeller counter-rotating equally, the water total amount that is write down reduces; For this reason, the utility model changes internal orifice dimension into the series of products that meet China's GB at the entery and delivery port place of water meter, as nominal diameter is that the dry-type meter of 13 millimeters of ∮ is all expanded as the 15-40 millimeter with the entery and delivery port internal diameter, 15 millimeters of optimum aperture ∮, and in the exit of water meter the direction in former duct to be changed be that the center line in direction and the duct that intakes of water delivering orifice inner duct intersects, the center line that becomes the water outlet duct is parallel with the center line in water inlet duct, and with water meter center line angle be 15 the degree, the roughness of its water-in and water-out internal channel is

After water flowed into from water inlet, current promoted impeller and are rotated counterclockwise, and impeller makes central gear rotate again, drive worm screw and make counter 6 counting forwards, after the user exchanged installation with water meter water inlet 1 and water delivering orifice 2, current promoted impeller along impeller 3 rotations and still are rotated counterclockwise, and make still counting forward of counter 6, therefore, this water meter has two-way function, and no matter entery and delivery port is arbitrarily exchanged, all can be accurately from direct-reading dish 8 above-noted actual used water amounts.

The advantage of this utility model is:

Owing on the principle basis of former German dry-type meter, improve, make it to form and meet China's GB water meter series of products, user's direct-reading water consumption can arbitrarily be exchanged the entery and delivery port of water meter again in use, and can prevent effectively that illegal user from stealing water, opened up the water saving new way, in addition because this water gauge body ponding, in light weight, outward appearance is novel, installations is simple, dial plate is not contaminated, meter reading is clear is the direct-reading effect again, at home and abroad market receives an acclaim, also can replace used tap water meter, application prospect is very wide.

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is " novel two-way water meter " structural representation.

Accompanying drawing 2 is " novel two-way water meter " structure schematic top plan view.

The structure of this utility model is made up of water meter water inlet 1, water delivering orifice 2, impeller 3, central gear 4, worm screw 5, counter 6, shell 7, direct-reading dish 8.The utility model only adds the original internal orifice dimension of the water delivering orifice 2 of water meter, water inlet 1 greatly 15 millimeters of ∮, internal orifice dimension direction with water delivering orifice 2 changes again, itself and inlet opening center line are parallel to each other, the roughness of its entery and delivery port internal channel is that 6.3 water meter measurements change the direct-reacting digital dish into, other parts need not to improve, and can reach the purpose of this utility model.

Claims (3)

1, a kind of two-way tap water meter of family's dry type of improvement type, form by water inlet 1, water delivering orifice 2, impeller 3, central gear 4, worm screw 5, counter 6, shell 7, direct-reading dish 8, it is characterized in that described water meter water delivering orifice internal orifice dimension expands as the 15-40 millimeter by 13 millimeters, 15 millimeters of optimum apertures, the direction of water delivering orifice inner duct parallels by intersecting to become with the center line in water inlet duct, its center line and water meter center line angle 15 degree.

2, two-way tap water meter according to claim 1: it is characterized in that: the counter 6 of water meter is the direct-reacting digital dish.
