Abstract

The utility model belongs to a device for supplying and metering pipeline gases. The utility model is provided with a base plate or a box body which is provided with a gas supplying main pipe which is closed on the head and is provided with a plurality of flow dividing openings on the pipe wall; meanwhile, the base plate or the box body is provided with a plurality of gas meters corresponding to the flow dividing openings; the flow dividing openings and the inlets of the corresponding gas meters are connected via a flow dividing pipe and a flow dividing valve, so that a channel for supplying and metering gases is formed. The inlets of the gas meters are used for installing special pipelines leading to users. The device of the utility model allows the gas meters to be in centralized management, avoids various defects of dispersed meter reading, has simple structure and easy implementation and is particularly favorable for the reconstruction of original old pipelines.

Description

A kind of feeder that is used for the gas meter, flow meter centralized management

The utility model relates to a kind of gas pipeline and carries feedway, particularly a kind of pipe air-supply device that is used for the gas meter, flow meter centralized management.

Current, the pipe gas that the city dweller uses, gauging table as coal gas, liquefied gas, natural gas etc., the problem that can not manage concentratedly of ubiquity all adopts single tube to carry their now, and gauging table disperses to be installed in every family, bring many difficulties to administrative authority, under the particularly present increasing situation of skyscraper, bring trouble for the work of checking meter, also influence user's rest and safety.It is one of method that solves the centralized management of gas-liquid gauging table that the multiple path co-pipe of Chinese patent 98108131.2 is carried feed system, has brought hope for administrative authority and user.

The purpose of this utility model provides and a kind ofly is different from the aforementioned tube pipeline conveying system, and a kind of feeder that is used for the gas meter, flow meter centralized management simple in structure, easy to implement.

The technical solution of the utility model is as follows:

This feeder that is used for the gas meter, flow meter centralized management, comprise substrate or casing, be installed in the fuel gas supply person in charge, valve and gas meter on substrate or the casing, special character is: the fuel gas supply of installing on substrate or casing is responsible for, its head sealing has several diffluence pass on the pipe sidewall; Discharging is installed on substrate or casing several gas meters, and the import of each gauging table is corresponding with the fuel gas supply person in charge's a diffluence pass; Between the diffluence pass that fuel gas supply is responsible for and the import of its corresponding gas meter, install and be connected with an isocon and by-pass valve, they are fused form the split channel of several fuel gas supplies and metering; Each gas meter has an outlet, leads to user's pipe special when installing and using in this outlet.The fuel gas supply of this feeder is responsible for, and can be mounted in the independent tubes of a head sealing on substrate or the casing, also can be the pipeline of the parallel connection of several head sealings.

This feeder that is used for the gas meter, flow meter centralized management, can not only solve gas meter, flow meter and install the problem that a place uses concentratedly, it is very convenient to manage, the various drawbacks of having avoided dispersion to check meter, simultaneously, because it is simple in structure, components and parts are conventional device and instrument, thereby easy to implement, be particularly advantageous in the transformation of original old piping system.

The utility model is described in further detail below by drawings and Examples:

Fig. 1 is an embodiment synoptic diagram of the present utility model;

Fig. 2 is that the B of Fig. 1 is to view;

Fig. 3 is embodiment 2 synoptic diagram of the present utility model;

Fig. 4 is embodiment 3 synoptic diagram of the present utility model;

Embodiment 1: consult Fig. 1, Fig. 2, one casing 2 is arranged, there is glass door 21 in its front, on the base plate 22 in the casing 2, the fuel gas supply that is horizontally installed with a head sealing by pipe clamp 23 is responsible for 1, and this supply person in charge 1 the other end has a total valve 4, when installing and using, the gas source pipeline is connected in this termination, has eight diffluence pass 11 on this supply person in charge 1 the downside tube wall; Eight cover gas meters 6 are gas measurement table commonly used, and their are arranged and are installed in fuel gas supply and are responsible on the base plate 22 of casing 2 of 1 below; Supply with and be responsible for eight diffluence pass 11 of 1, by isocon 3 and import 61--corresponding be connected of by-pass valve 5 with each gas meter 6, thereby the split channel that forms eight fuel gas supplies and measure; Each gas meter 6 has an outlet 62, the pipe special that when installing and using, leads to the user in order to connection, this example is supplied coal gas for the user who installs to eight floor rooms, therefore can use the PAP 7 of bending arbitrarily to be connected with gas meter outlet 62, its other end directly leads to required floor user, and the centre need not increase interface unit.

Embodiment 2: consult Fig. 3, a substrate 2 ' on one group of fuel gas supply that is combined by two discharge pipes up and down be installed be responsible for 1 ', their head sealing, tail end be communicated in one and be equipped with total valve 4 ', when installing and using, this tail end is connected the gas source pipeline; Up and down two row's fuel gas supplies be responsible for 1 ' the downside tube wall respectively have four diffluence pass 11 ', they lower substrate 2 ' on correspondence be equipped with two row and every row's quadruplet gas meter 6 ', gas meter 6 ' import 61 ' be responsible for 1 with corresponding fuel gas supply ' diffluence pass 11 ' between, by isocon 3 ' and by-pass valve 5 ' they are connected in one the split channel that forms eight fuel gas supplies and measure; Each gas meter 6 ' have outlet 62 ', when installing and using, in order to connection lead to user's pipe special 7 ', with embodiment 1, repeat no more.

Embodiment 3: consult Fig. 4, the present embodiment scheme comprises fuel gas supply be responsible for 1 ", substrate 2 " and gas meter 6 "; and above-mentioned two embodiment differences are: fuel gas supply is responsible for the central authorities of 1 " vertically being installed in substrate 2 ", its head sealing upwards, the both sides tube wall respectively has three diffluence pass 11 "; Be responsible for 1 at fuel gas supply on " both sides substrate 2 ", three cover gas meters 6 respectively are installed "; The diffluence pass 11 of the import 61 of gas meter 6 " " " and fuel gas supply be responsible for 1 " "--correspondence, and is connected by isocon 3 " with by-pass valve 5 ", form the split channel that six fuel gas supplies also measure; Gas meter 6 " outlet 62 " can be installed the pipe special that leads to each user.
