Problems solved by technology

[0003] At present, both domestic and foreign horizontal water meters and vertical water meters are limited by the overall layout design of the mechanical character wheel gear set and the impeller. The base meter and the control valve can only be installed on the outlet pipe of the original mechanical vertical water meter. The base meter has the following disadvantages: large volume, complex structure, difficult manufacturing, many knuckles, large pressure loss, large space occupation, and high cost.
[0004] A small number of buildings are equipped with water tanks on the top, and the water supply method is from top to bottom. Since there is no vertical water meter dedicated to this water supply method, horizontal water meters can only be installed horizontally to solve the above problems.

Embodiment 1

[0016] like figure 1 As shown, a coaxial two-way vertical base meter with a valve is suitable for small-diameter smart water meters, including a water meter housing 1, a filter screen 3, a diversion inclined hole 4, a diversion chamber 5, a rotor impeller 6, a guide Flow chamber water outlet 9 and control valve 10. The control valve 10 can be selected from a ball valve, a pilot valve or a stop valve.

[0017] A water meter water inlet 2 is provided at the bottom of the water meter housing 1, and a water meter water outlet 11 is provided at the top. Water meter water inlet 2, filter screen 3, diversion inclined hole 4, diversion chamber 5, rotor impeller 6, diversion chamber water outlet 9, control valve 10 and water meter outlet 11 are arranged in sequence from bottom to top, and the central axis same.

[0018] The upper part of the rotor-type impeller 6 is inlaid with a stainless steel sheet 7, and the side of the water meter housing 1 is fixed with a metal detection senso...

Embodiment 2

[0021] like figure 2 As shown, a coaxial two-way vertical base meter with a valve is suitable for large-diameter smart water meters, including a water meter casing 1 , a screw-wing impeller 12 , an impeller bracket 13 and a control valve 10 . The control valve 10 can be selected from a ball valve, a pilot valve or a stop valve.

[0022] A water meter water inlet 2 is provided at the bottom of the water meter housing 1, and a water meter water outlet 11 is provided at the top. The water meter water inlet 2, the impeller bracket 13, the screw-wing impeller 12, the control valve 10 and the water meter water outlet 11 are arranged sequentially from bottom to top, and the central axes are the same. The base meter has large flow rate and small pressure loss, and is suitable for large-diameter water meters.

[0023] The upper part of the screw-wing impeller 12 is inlaid with a stainless steel sheet 7, and the side of the water meter housing 1 is fixed with a metal detection sensor...

Abstract

The invention relates to an intelligent water meter, in particular to a coaxial two-way valved vertical basic meter for an intelligent water meter. The coaxial two-way valved vertical basic meter comprises a meter housing, a blade wheel and a control valve. The blade wheel and the control valve are mounted inside the meter housing. the axes of the meter housing, the blade wheel and the control valve are identical; axes of a water meter inlet, the blade wheel and a water meter outlet are identical; a metal sheet is embedded in the upper portion of the blade wheel; a metal detection sensor probecorresponding to the metal sheet is fixed to the side of the meter housing. The coaxial two-way valved vertical basic meter is applicable to various intelligent water meters, has the advantages of simple structure, small size, light weight, good manufacture convenience, good disassembly convenience, high metering precision, high flow, low initial flow, low pressure loss, high interference resistance, low failure rate, low water quality requirement, low space consumption, low manufacture cost and the like, and helps fill the blank of an intelligent water meter that supplies water from top to bottom.

Description

technical field [0001] The invention relates to an intelligent water meter, in particular to a coaxial two-way vertical base meter with a valve for the intelligent water meter. Background technique [0002] With the development of urban water supply and the continuous improvement of the service quality of residents' water requirements, most of the newly-built buildings adopt the layout of water meters, and the consumption of vertical smart water meters continues to increase. [0003] At present, both domestic and foreign horizontal water meters and vertical water meters are limited by the overall layout design of the mechanical character wheel gear set and the impeller. The base meter and the control valve can only be installed on the outlet pipe of the original mechanical vertical water meter. The base meter has the following disadvantages: large volume, complex structure, difficult manufacturing, many knuckles, large pressure loss, large space occupation, and high cost. ...
