Abstract
The utility model provides a kind of counterflow-preventing thin-wall stainless steel water meter housing, including water inlet pipe, outlet pipe and main casing, the water inlet pipe, outlet pipe is symmetrically welded at the intermediate two sides of main casing, the nozzle of the water inlet pipe or outlet pipe sets a seam allowance ring, the seam allowance ring is welded on water inlet pipe or effluent pipe mouth inner wall, the seam allowance ring is for installing reverse flow check valve device, the utility model is by adding seam allowance ring, to solve the problems, such as that the following water meter of wall thickness 2mm can not install counterflow prevention check valve device, to make water meter have counterflow-preventing, anti- autobiography, the function of anti-turn.
Description
Technical field
The utility model relates to a kind of water meter housings, refer in particular to a kind of counterflow-preventing thin-wall stainless steel water meter housing.
Background technique
Water meter housing is usually all made of also to be had using cast iron, copper, stainless steel material and aluminum alloy material newly occurred at present
Shell of water flowmeter, either cast iron, copper watchcase or aluminum watchcase different degrees of material can all occur in water meter use process and be precipitated
And polluted source, water meter industry is it has been proposed that eliminate iron watchcase, and in addition the shell of water flowmeter of monoblock type wall thickness is unfavorable for forming, and model takes
With relatively high, thin-wall stainless steel watchcase is mostly used greatly currently on the market, but since the following water meter of wall thickness 2mm can not install counterflow-preventing
Check valve apparatus, so that water meter be made to be unable to satisfy counterflow-preventing, anti-autobiography, anti-down rotating function.
Utility model content
The utility model aim is to provide a kind of counterflow-preventing thin-wall stainless steel water meter housing, by adding seam allowance ring, from
And solve the problems, such as that the following water meter of wall thickness 2mm can not install counterflow prevention check valve device, so that water meter be made to have counterflow-preventing, prevent
The function of autobiography, anti-turn.To realize above-mentioned purpose, the utility model adopts the following technical scheme:
A kind of counterflow-preventing thin-wall stainless steel water meter housing, including water inlet pipe, outlet pipe and main casing, the water inlet pipe,
Outlet pipe is symmetrically welded at the intermediate two sides of main casing, and the nozzle of the water inlet pipe or outlet pipe sets a seam allowance ring, the seam allowance
Ring is welded on water inlet pipe or effluent pipe mouth inner wall.
Further, the seam allowance ring is stainless steel part.
Further, the seam allowance ring with a thickness of 3-4mm.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, the utility model
By adding seam allowance ring, to solve the problems, such as that the following water meter of wall thickness 2mm can not install counterflow prevention check valve device, to make
Water meter have counterflow-preventing, anti-autobiography, anti-turn function.
Detailed description of the invention
Fig. 1 is the utility model entirety cut-away view；
Drawing reference numeral explanation:
1, water inlet pipe 2, outlet pipe 3, main casing
4, seam allowance ring 5, check valve apparatus
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
The utility model is further described with specific embodiment with reference to the accompanying drawing.
Refering to Figure 1, a kind of counterflow-preventing thin-wall stainless steel water meter housing, including water inlet pipe 1, outlet pipe 2 and master
Shell 3, the water inlet pipe 1, outlet pipe 2 are symmetrically welded at the intermediate two sides of main casing 3, the pipe of the water inlet pipe 1 or outlet pipe 2
Mouth sets a seam allowance ring 4, and the seam allowance ring 4 is stainless steel part, and with a thickness of 3-4mm, the seam allowance ring 4 is welded on water inlet pipe 1
Or 2 mouthfuls of inner walls of outlet pipe, the seam allowance ring 4 is for installing reverse flow check valve device 5.
The utility model passes through the utility model by adding seam allowance ring 4, so that solving the following water meter of wall thickness 2mm can not
Install counterflow prevention check valve device 5 the problem of, thus make water meter have counterflow-preventing, anti-autobiography, anti-turn function.
The above is only the utility model preferred embodiment, not appoints to the technical scope of the utility model
What is limited, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent variations
With modification, it is still within the scope of the technical solutions of the present invention.
