Abstract

The utility model discloses a water meter chamber, which makes a water meter 10 arranged on a prefabricated box body 12, wherein, a heat preservation cover 13 is arranged on the box body 12; the water inlet end and the water outlet end of the water meter 10 are respectively provided with a valve 3 and a valve 14; a rubber pad 1 and a plastic pad 2 are arranged between the valves 3 and 14 and the inner side wall of the box body 12; one end of the valve 3 is provided with a jacket precursor 4; an expansion pipe 8 is connected with the water meter 10; a pipe diameter is inserted into the jacket precursor 4; then a fixing inclined plate 7 is arranged on the pipe diameter 16 of the expansion pipe 8; the other end of the water meter 10 is connected with a variable diameter jacket precursor 11; the variable diameter jacket precursor 11 is inserted in the joint of the valve 14. The connection of each part of the water meter chamber is inserting. Then the water meter chamber can stop the disassembling difficulty caused by rust threads in thread connection. The water meter chamber is prefabricated. Thus the utility model has the advantages of convenient construction and low cost.

Description

A kind of water meter chamber

The utility model relates to a kind of tap water water meter well.

In order to give the tap water user metering, the tap water water meter must be installed on the tap water water pipe.The tap water water meter well that uses is owing to build at the construction field (site) now, and bulky, cost height, water meter chamber are also very dark, brings difficulty for the maintenance water meter.Be thread connection between the front and back valve of water meter and water meter particularly, service time one is long, and screw thread gets rusty, and it is all very difficult to change water meter and valve.

The purpose of this utility model provides a kind of tap water water meter well, and in this water meter chamber, the connection between each part is all pegged graft.

The purpose of this utility model is achieved in that

Give system one casing earlier, water meter is installed giving in the casing that makes.Between valve in the casing and water meter, insert one to the valve interface place earlier and overlap mother, add a packing ring then, water meter one end is injected in the big endoporus of draw-tube, and the caliber of draw-tube inject in cover mother, the packing ring endoporus, adds fixedly swash plate then outside the draw-tube caliber; The water meter other end injects in the female big endoporus of drill holder, and drill holder mother inject in the valve interface again.

The water meter chamber that the utility model provides, because water meter is mounted in the casing of the system of giving, therefore water meter chamber is constructed rapidly, save labor, reduced the water meter chamber cost, shortened construction period, particularly the connection between each part all is to peg graft in the water meter chamber, rather than thread connection, therefore dismantle water meter easily and fast, created condition for replacing water meter, valve.

Further introduce the utility model below by accompanying drawing.

Accompanying drawing one is a cut-open view of the present utility model.

Accompanying drawing two is the front elevation of cover female 4.

Accompanying drawing three is the vertical view of cover female 4.

Accompanying drawing four is the fixing front elevation of swash plate 7.

Accompanying drawing five is the fixing vertical view of swash plate 7.

Accompanying drawing six is the cut-open view of draw-tube 8.

Accompanying drawing seven is drill holder mother 11 a front elevation.

Accompanying drawing eight is drill holder mother 11 a vertical view.

Can see that from accompanying drawing water meter 10 is mounted in and gives 12 li of the meter boxs that make, meter box 12 can be a sheet metal manufacturing, also can be other made, is subjected to freeze injury in the winter time in order to prevent water meter, and table case 12 has the case lid 13 of band heat-insulation layer.Water meter 10 is mounted in the middle part of meter box 12, the both sides of water meter 10 are valve 3 and valve 14, valve has two, in the water inlet end of water meter 10 and water side each one, rubber blanket 1 and plastic mattress 2 are arranged between the madial wall of valve 3 and casing 12, because water pipe and valve 3 are pegged graft, rubber blanket 1 and plastic mattress 2 seal.The other end of valve 3 is cover mothers 4, and cover female 4 utilizes its caliber to inject in the interface of valve 3, and cover mother 4 is joined with O type cushion rubber 5, packing ring 6 again.Water meter 10 1 ends inject in the big endoporus 15 of draw-tube 8, have also added rubber blanket 9 in order to seal.And the caliber 16 of draw-tube 8 injects in the endoporus of cover mother 4, packing ring 6.Outside the caliber 16 of draw-tube 8, add fixedly swash plate 7, fixedly swash plate 7 has two, by the two fixedly adjustings on swash plate 7 inclined-planes, the caliber 16 of just having regulated draw-tube 8 injects the length of female 4 li of cover, thus also just water meter 10 under the stationkeeping on 12 li pipelines of meter box.Water meter 10 other ends inject in drill holder mother 11 the big endoporus 17, also added O-ring seal 9 in order to seal, drill holder mother 11 makes its caliber inject in the interface of another valve 14 again, and also be rubber blanket 1 and plastic mattress 2 between the sidewall of valve 14 and meter box 12, and water pipe is injected in another interface of valve 14.

Claims

1. water meter chamber, be that water meter is installed in the casing (12) of the system of giving, it is characterized by: between valve (3) and water meter (10), insert a cover female (4) to valve (3) interface, add a packing ring (6) then, water meter (10) one ends are injected in the big endoporus (15) of draw-tube (8), and the caliber (16) of draw-tube (8) injects in cover female (4), packing ring (6) endoporus, and adds fixedly swash plate (7) outside draw-tube caliber (16); Water meter (10) other end injects in the big endoporus (17) of drill holder mother (11), and drill holder mother (11) injects in the interface of another valve (14) again.
