Abstract
The utility model relates to a leak detection device in atmospheric valve, including the blow -down pipe, install the atmospheric valve on the blow -down pipe, at the export series connection low pressure stop valve of atmospheric valve, the gaseous low pressure stop valve that passes through of unloading is after the manometer is installed to the blow -down pipe atmospheric dilution on the unloading pipeline section between atmospheric valve and low pressure stop valve, and the valve is shown to the setting pressure on the manometer in addition, and the length of pipeline section is 0.8m -1.0m between atmospheric valve and the low pressure stop valve. The utility model discloses can cross interior the hourglasss phenomenon of in time discovering the atmospheric valve, leakage quantity in depositing that the formula is rough and calculate according to the pipe, the waste of the reduction energy, simultaneously the utility model discloses the scheme principle is simple, and is with low costs, and the practicality is strong, is fit for the marketing.
Description
Technical field
The utility model belongs to the atmospheric valve technical field of rock gas mother station, particularly a kind of atmospheric valve inner hexagon device.
Background technology
Tradition exhausting pipeline technique is single, exhausting pipeline is direct discharged to air after connecting atmospheric valve, and in the system cloud gray model of reality, atmospheric valve is even has slight interior phenomenon of leaking to occur, because the slight interior of atmospheric valve leaks on measurement shoutage impact not quite, not easily discovered, but natural gas via can be caused to be discharged in air by blow-down pipe, formed energy dissipation.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of atmospheric valve inner hexagon device.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of atmospheric valve inner hexagon device, comprise blow-down pipe, in the end of blow-down pipe, atmospheric valve is installed, to connect a low-pressure shutoff valve in the outlet of atmospheric valve, emptying gas enters air through blow-down pipe after being exported by low-pressure shutoff valve, and the pipeline section between atmospheric valve and low-pressure shutoff valve is provided with tensimeter.
And, setting pressure meter valve on tensimeter.
And the length of pipeline section is 0.8m-1.0m between atmospheric valve and low-pressure shutoff valve.
Advantage of the present utility model and good effect are:
1, the utility model can cross the interior leakage phenomenon of Timeliness coverage atmospheric valve, deposits leakage quantity in formula rough calculation according to pipe, reduces energy dissipation.
2, the utility model solution principle is simple, and cost is low, practical, is applicable to marketing.
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 atmospheric valve inner hexagon device, as shown in Figure 1, comprise blow-down pipe, in the end of blow-down pipe, atmospheric valve 1 is installed, innovative point of the present utility model is, to connect a low-pressure shutoff valve 4 in the outlet of atmospheric valve, emptying gas enters air through blow-down pipe after being exported by low-pressure shutoff valve, the pipeline section between atmospheric valve and low-pressure shutoff valve is provided with tensimeter 2.
In concrete enforcement of the present utility model, setting pressure meter valve 3 on tensimeter.
In concrete enforcement of the present utility model, between atmospheric valve and low-pressure shutoff valve, the length of pipeline section is 0.8m-1.0m, effectively can detect the pressure change produced owing to leaking in atmospheric valve.
Principle of work
Close low pressure block valve under atmospheric valve closed condition, open the tensimeter on pipeline section between two valves, because between two valves, straight length is airtight, if leak in atmospheric valve, straight length pressure increase, observes tensimeter indicating value and can judge the whether interior leakage of atmospheric valve, also can deposit leakage quantity in formula rough calculation according to pipe.
