Abstract
The utility model discloses a measurable compressed natural gas safely unloading device. The measurable compressed natural gas safely unloading device consists of a gas discharge pipeline, an anti-explosion instrument panel and a box body, wherein the gas discharge pipeline comprises a snapping valve, an inlet valve, a filter, a flow meter and an outlet valve which are connected in series by a pipeline; an emptying valve is arranged on the pipeline between the snapping valve and the inlet valve; the pipeline between the flow meter and the outlet valve is provided with a pressure meter; the emptying valve, the inlet valve, the filter, the flow meter, the pressure meter and the outlet valve are arranged in a rectangular box body; the snapping valve is arranged outside the box body; an outlet pipeline of the emptying valve extends out of the box body; the box body is internally provided with the anti-explosion instrument panel connected with the flow meter by a lead. The measurable compressed natural gas safely unloading device provided by the utility model has the advantages that the unloading device is simple in structure, is accurate in metering, is low in investment cost, is easy to implement, is safe and convenient, can effectively prevent gas leakage caused by the flexible pipe snapping especially when the unloading flexible pipe is forgotten to be detached after unloading, prevents greater damage to people and equipment, and guarantees the unloading safety.
Description
(1) technical field
The utility model relates to liquefied natural gas facility, particularly the safe unloading unit of a kind of gageable compressed natural gas.
(2) background technique
Compressed natural gas is low using cost, high efficiency, pollution-free, use the feature such as safe and convenient to be widely used on industrial and civilian and automobile-used alternative energy source as clean energy resource.Compressed natural gas is that well head rock gas or pipe natural gas are purified to the laggard horizontal high voltage storage of compression and transportation, arrives place to use, by sebific duct and unloading unit, pressurized gas is imported to gas equipment from tank car.The unloading unit adopting at present is just provided with merely pipeline, main road valve, atmospheric valve etc., cannot measure gas flow, after can not preventing from unloading because forgetting that dismounting unload flexible pipe or flexible pipe are pulled off danger such as causing Leakage Gas.
(3) model utility content
The purpose of this utility model is for above-mentioned existing problems, provide a kind of gageable compressed natural gas safe unloading unit, this apparatus structure is simple, metering is accurate, cost of investment is low, easy to implement, safe and convenient, particularly after unloading, remove when unload flexible pipe because forgetting, this device can effectively play and prevent that flexible pipe is pulled off and the gas leakage that causes is avoided the effect of the larger harm that causes personnel and equipment.
The technical solution of the utility model:
The safe unloading unit of a kind of gageable compressed natural gas, by unloading air pipe, explosion-proof instrument dial plate and casing composition, unload air pipe and comprise Pull breaking ualve, inlet valve, filter, flowmeter and outlet valve are also connected in series by pipeline, pipeline between Pull breaking ualve and inlet valve is provided with atmospheric valve, pipeline between flowmeter and outlet valve is provided with pressure gauge, atmospheric valve, inlet valve, filter, flowmeter, pressure gauge and outlet valve are arranged in rectangular box, Pull breaking ualve is arranged at casing outside, the outlet conduit of atmospheric valve stretches out outside casing, in casing, be provided with explosion-proof instrument dial plate and be connected with flowmeter by wire.
Working principle of the present utility model:
This unloading unit is in the time of normal operation, compressed natural gas passes through Pull breaking ualve by unload flexible pipe and enters box house pipeline, through the laggard inbound traffics meter of filter, flowmeter passes to the data such as instantaneous flow, integrated flow in unloading unit explosion-proof instrument dial plate, thereby allow user obtain gas flow value accurately, enter downstream line arrival gas equipment finally by crossing outlet valve.After unloading, Pull breaking ualve can effectively prevent because forgetting dismounting unload flexible pipe, and flexible pipe is pulled off and causes the danger of gas leakage.When the pulling force that Pull breaking ualve bears is greater than rating value, can automatically disconnect, and gap two automatic-sealed, and after Pull breaking ualve manual reset, can repeat to break use.
The utility model has the advantages that: the safe unloading unit of this gageable compressed natural gas is simple in structure, metering is accurate, cost of investment is low, easy to implement, safe and convenient, particularly after unloading, remove when unload flexible pipe because forgetting, this device can effectively play and prevent that flexible pipe is pulled off and the gas leakage that causes, avoid causing the larger harm of personnel and equipment, guarantee the safety of unloading.
