Abstract
The utility model relates to a kind of combustible gas metering arrangement with auto-lock function, comprise metering pipeline and the bypass line being connected in parallel on metering pipeline two ends, the inlet ball valve that described metering pipeline is connected successively by high pressure pipe line, y-type filter, Intelligent Turbine Flowmeter and vent ball valve are formed, and the release valve ball with auto-lock function that described bypass line is connected in series by high pressure pipe line is formed.In the utility model device, the bypath valve of Intelligent Turbine Flowmeter is with auto-lock function, when gas company works with flowmeter one tunnel with Trade Measures function, the bypath valve of flowmeter is in blocking, effectively prevent the generation by flowmeter bypath valve gas phenomenon.
Description
Technical field
The utility model belongs to natural gas pressure regulating device technique field, particularly a kind of combustible gas metering arrangement with auto-lock function.
Background technique
Along with rapid development of economy, be that the situation day of the energy is becoming tight with oil.The fuel of people's productive life no longer only depends on coal, wet goods fuel, and rock gas becomes rapidly main flow fuel as the new energy of cleanliness without any pollution.But because gas company is in the process of dealing rock gas, usually have buyer and utilize the bypath valve of flowmeter to steal the phenomenon of gas, in order to address this problem, this just needs a kind of combustible gas metering arrangement with auto-lock function.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of combustible gas metering arrangement with auto-lock function.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of combustible gas metering arrangement with auto-lock function, it is characterized in that: comprise metering pipeline and the bypass line being connected in parallel on metering pipeline two ends, the inlet ball valve that described metering pipeline is connected successively by high pressure pipe line, y-type filter, Intelligent Turbine Flowmeter and vent ball valve are formed, and the release valve ball with auto-lock function that described bypass line is connected in series by high pressure pipe line is formed.
And, the model that described inlet ball valve adopts is: Q41F-16C DN100, the model that described y-type filter adopts is: GL41H-16C DN100, the model that described Intelligent Turbine Flowmeter adopts is: LWQZ-100C PN16, measuring accuracy 1.0 grades, the model that described vent ball valve adopts is: Q41F-16C DN100, the model that the described release valve ball with auto-lock function adopts is: Q41F-16C DN100.
Advantage of the present utility model and good effect are:
In the utility model device, the bypath valve of Intelligent Turbine Flowmeter is with auto-lock function, when gas company works with flowmeter one tunnel with Trade Measures function, the bypath valve of flowmeter is in blocking, if do not had " key ", this bypath valve can not be opened, and effectively prevent combustion gas buyer steals gas phenomenon generation by the bypath valve of flowmeter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of combustible gas metering arrangement with auto-lock function, as shown in Figure 1, comprise metering pipeline and the bypass line being connected in parallel on metering pipeline two ends, the inlet ball valve 1 that described metering pipeline is sequentially connected in series by high pressure pipe line, y-type filter 2, Intelligent Turbine Flowmeter 3 and vent ball valve 4 are formed, and the release valve ball 5 with auto-lock function that described bypass line is connected in series by high pressure pipe line is formed.
As instantiation of the present utility model, the model that described inlet ball valve adopts is Q41F-16C DN100, the model that described y-type filter adopts is GL41H-16C DN100, the model that described Intelligent Turbine Flowmeter adopts is LWQZ-100C PN16, measuring accuracy 1.0 grades, the model that described vent ball valve adopts is Q41F-16C DN100, and the model that the described release valve ball with auto-lock function adopts is Q41F-16C DN100.
Working principle
When this measuring apparatus normally runs, first the inlet ball valve of metering pipeline is slowly opened, open the vent ball valve after Intelligent Turbine Flowmeter, the consumption of the rock gas passed through is understood by the registration of Intelligent Turbine Flowmeter, thus the metering clearing that carry on trade, when Intelligent Turbine Flowmeter breaks down, with " key " the bypath valve of turn-on flow rate meter, close the front and back valve of flowmeter pipeline, to ensure the demand of the uninterrupted air feed of user, if do not had " key ", the bypath valve of flowmeter can not be opened, user is effectively prevented to utilize the bypath valve of flowmeter to steal the phenomenon of gas.
