The utility model is characterized in that: an auxiliary pressure regulator (9) is arranged between the air inlet pipeline (1) and the air outlet pipeline (7) and is in parallel connection with the main pressure regulator (5), two ends of the auxiliary pressure regulator (9) are connected with valves. The pressure regulation appliance for gas supply of the utility model has reasonable structure, can guarantee continuous gas supply; the main pressure regulator and the auxiliary pressure regulator are shifted conveniently and the operation is safe.
Description
Technical field
The utility model relates to a kind of air feed regulator that is used for combustion gas, is specifically related to a kind of air feed regulator that combustion gas is reduced to the lower pressure 0.0025MPa of domestic gas use from higher pressure 0.3～0.4MPa.
Background technique
The air feed regulator that is used for combustion gas is most important gas transmission and distribution facility, and its safe operation is directly connected to the safe way to the user.The existing air feed regulator that is used for combustion gas is the single channel air supply system, when in case the air feed regulator of combustion gas need overhaul, just must stop the supple of gas or steam to the building of this air feed, but after stopping the supple of gas or steam again intercourse meeting this building user's the person and property safety caused certain hidden danger.
People's Republic of China's industry standard " city gas facility operation, maintenance and repairing emergency decree " of new promulgation (CJJ51-2006) explicitly calls for: the ventilation after the user is stopped the supple of gas or steam, should after notifying the user effectively, carry out.Yet, in built-up modernized city, also use existing gas supply regulator, before ventilation, notify each tame user effectively, obviously be difficult to accomplish.
Summary of the invention
The purpose of this utility model is to provide gas supply regulator a kind of rational in infrastructure, easy to use, safe.
The purpose of this utility model is achieved in that a kind of gas supply regulator, comprise admission line, outlet pipe, be separately positioned on inlet end valve and outlet side valve on admission line and the outlet pipe, and the two ends main voltage regulator and the cut-off valve of fixedlying connected with outlet pipe with admission line respectively, it is characterized in that: between described admission line and outlet pipe, set up with described main voltage regulator parallel connection, two ends are connected valvular secondary pressure governor.
Fixedly connected with an end of inlet end auxiliary-valve and outlet side auxiliary-valve through pipe fitting respectively in the two ends of above-mentioned secondary pressure governor, the other end of described inlet end auxiliary-valve and described admission line are fixedly connected on before the described inlet end valve, and the other end of described outlet side auxiliary-valve and described outlet pipe are fixedly connected on after the valve of described outlet side; On the pipeline of described secondary pressure governor outlet side, be provided with the pressure measurement mouth.
Above-mentioned inlet end valve, inlet end auxiliary-valve, outlet side valve and outlet side auxiliary-valve are to use ball valve preferable.
Inlet end at above-mentioned main voltage regulator is connected with filter and pressure gauge, and is connected with the pressure measurement mouth on the pipeline of outlet side.
In the gas supply regulator of the present utility model, main voltage regulator, secondary pressure governor, cut-off valve, filter and pressure gauge are conventional equipment, wherein the air feed minimum discharge of secondary pressure governor can be 4 cubic metres/hour～10 cubic metres/hour, keeps to satisfy that a building user is minimum to be selected with the gas load.
The air feed regulator that is used for combustion gas of the present utility model carries out the work of pressure regulation air feed by main voltage regulator when normal the use, the valve at secondary pressure governor two ends is in closed condition, and secondary pressure governor is not worked; In the time need carrying out necessary maintaining or repairing to component such as main voltage regulator, cut-off valve, filter, pressure gauges, then can enable secondary pressure governor: at first manometer is connected to secondary pressure governor pressure measurement mouth afterwards, open pressure valve, slowly open the inlet end auxiliary-valve then, the closing pressure of secondary pressure governor is adjusted to predetermined value, slowly open the outlet side auxiliary-valve again, make secondary pressure governor begin the work of pressure regulation air feed, keep that a building user is minimum to load with gas, close inlet end valve and outlet side valve immediately, carry out corresponding maintaining or repairing; When the maintaining or the repairing of main voltage regulator finishes, and during normal operation, then can close the valve at secondary pressure governor two ends, make secondary pressure governor be in stand-by state, avoided maintenance because of the air feed regulator to the problem of stopping the supple of gas or steam that the user brings effectively, stopped and eliminated after stopping the supple of gas or steam again that ventilation may cause certain hidden danger to user's the person and property safety.
Therefore, the air feed regulator that is used for combustion gas of the present utility model is rational in infrastructure, can guarantee that air feed is uninterrupted, and major and minor pressure governor handover operation is convenient and safe in utilization.
