Abstract

The utility model relates to a gas source distributor capable of realizing centralized gas supply, which is characterized by comprising a gas container, branch pipes and branch valves, wherein one end of the gas container is provided with a flange, the flange is connected with a flange of a gas source main pipe, the other end of the gas container is provided with a blow-off pipe, a blow-off ball valve is arranged on the blow-off pipe, more than two branch pipes are arrayed on the gas container, and the branch valves are respectively arranged on the branch pipes. The branch pipes can be designed into branch pipes with different calibers as needed. Compared with the prior art, the gas source distributor capable of realizing centralized gas supply has the following beneficial effects that: (1) the gas source distributor can be arranged close to a pneumatic adjusting valve and a pneumatic cutoff valve as planned so as to realize 'centralized gas supply' and effectively improve the reliability of gas supply pipelines of the pneumatic adjusting valve and the pneumatic cutoff valve; (2) if a valve needs to be additionally mounted in production, the valve only needs to be connected with the branch pipes, so that the maintenance workload in the later stage is reduced; and (3) the gas source distributor can be connected with pneumatic adjusting valves with different connectors and has good universality.

Description

A kind of source of the gas distributor of central gas supply

Technical field

The utility model relates to petrochemical industry, chemical field, relates in particular to a kind of source of the gas distributor of central gas supply.

Background technique

In petrochemical industry and chemical industry,, a large amount of pneumatic control valves and pneumatic cut-off valve have been adopted at present according to the requirement of national explosion-proof criteria and factory safety property; Complicated because of process pipe, cause the pneumatic control valve position to disperse, every pneumatic control valve is by a copper pipe air feed; Very inconvenient when planning and design supply air line, because the supply air line of pneumatic control valve and pneumatic cut-off valve is oversize, receive mechanical deterioration easily in addition; And constructional difficulties, the later maintenance amount is big, the malfunction elimination difficulty.

Summary of the invention

The purpose of the utility model provides a kind of source of the gas distributor of central gas supply, improves the reliability of the supply air line of pneumatic control valve and pneumatic cut-off valve, reduces the later maintenance workload.

For solving the problems of the technologies described above, the technological scheme of the utility model is:

A kind of source of the gas distributor of central gas supply; Comprise air-capacitor, bypass duct, bypass valve; Air-capacitor one end is provided with flange and is connected with air supply manifold's flange, and the air-capacitor the other end is provided with drain pipe, and drain pipe is provided with Blowoff ball valve; Be arranged with the bypass duct more than two on the air-capacitor, be respectively equipped with bypass valve on the bypass duct.

Compared with prior art; Near the beneficial effect of the utility model: 1) can be arranged on pneumatic control valve and the pneumatic cut-off valve according to this device of planning; Realize " unified air feed ", effectively improved the reliability of the supply air line of pneumatic control valve and pneumatic cut-off valve.2) produce in as increase mounted valve, only need valve is connected with bypass duct and get final product reduction later maintenance workload.3) can connect the pneumatic control valve of distinct interface, versatility is good.

Among the figure: 1-air-capacitor 2-bypass duct 3-bypass valve 4-flange 5-air supply manifold 6-drain pipe 7-Blowoff ball valve

Embodiment

Be described further below in conjunction with the embodiment of accompanying drawing the utility model:

See Fig. 1; Be the source of the gas distributor example structure schematic representation of a kind of central gas supply of the utility model, comprise air-capacitor 1, bypass duct 2, bypass valve 3, air-capacitor 1 one ends are provided with flange 4 and are connected with air supply manifold 5 flange; Air-capacitor 1 the other end is provided with drain pipe 6; Drain pipe 6 is provided with Blowoff ball valve 7, is arranged with ten bypass duct 2 on the air-capacitor 1, is respectively equipped with bypass valve 3 on the bypass duct 2.This distributor leaves enough pipeline quantity when design, even the later stage adds pneumatic valve, also need not lay air supply pipe again, is convenient to construction.

Bypass duct 2 bore as required is different, can be connected with copper pipe with the pneumatic control valve of distinct interface, guarantees versatility, and pipeline expense expenditure significantly reduces.

Claims

1. the source of the gas distributor of a central gas supply; It is characterized in that, comprise air-capacitor, bypass duct, bypass valve, air-capacitor one end is provided with flange and is connected with air supply manifold's flange; The air-capacitor the other end is provided with drain pipe; Drain pipe is provided with Blowoff ball valve, is arranged with the bypass duct more than two on the air-capacitor, is respectively equipped with bypass valve on the bypass duct.
