[utility model content]
The purpose of this utility model is exactly will solve above-mentioned deficiency and provide a kind of metering system with mass flowmeter, adopt into sledgeization design, wider to the degree of purity scope of application of gas medium, and to the almost no requirement (NR) of front and back straight length, substantially reduce the size that metering sledge takes up room, more field requirement can be met.
Design a kind of metering system with mass flowmeter for achieving the above object, comprise sledge seat 1, described sledge seat 1 is provided with metering pipeline 2, described metering pipeline 2 is provided with entrance and cuts off ball valve 3, mass flowmeter 4 and forced seal valve 5, described entrance cuts off the inlet end that ball valve 3 is arranged on metering pipeline 2, described forced seal valve 5 is arranged on the endpiece of metering pipeline 2, described entrance cuts off the inlet end of the endpiece quality of connection flowmeter 4 of ball valve 3, the endpiece of described mass flowmeter 4 connects the inlet end of forced seal valve 5, pipeline between described mass flowmeter 4 and forced seal valve 5 is provided with absolute pressure transmitter 6 and integrative temperature transmitter 7, the inlet end of the endpiece connecting integration temperature transmitter 7 of described absolute pressure transmitter 6, described mass flowmeter 4, absolute pressure transmitter 6, integrative temperature transmitter 7 is respectively by connection flow computer.
Described metering pipeline 2 is provided with two, described two metering pipelines 2 comprise metering main line and metering spare duct, described metering main line and metering spare duct are installed in parallel on sledge seat 1, described metering main line, metering spare duct are all provided with entrance and cut off ball valve 3, mass flowmeter 4, absolute pressure transmitter 6, integrative temperature transmitter 7 and forced seal valve 5.
Described mass flowmeter 4 is provided with flow transmitter 8, and described absolute pressure transmitter 6, integrative temperature transmitter 7 are arranged on the pipeline of mass flowmeter 4 endpiece.
The utility model compared with the existing technology, novel structure, simple, reasonable in design, due in the metering system of rock gas station, service property (quality) flowmeter carries out the flow measurement of rock gas, to replace traditional ultrasonic flow meter and turbo flow meter, thus avoid in traditional approach the use limitation that the cleanliness factor of medium and front and back straight length all have high requirements brought; And, by being provided with two metering pipelines, make one road as use road for normal metering, road for subsequent use, as road for subsequent use, when main road flowmeter breaks down or need to demarcate main road flowmeter time, can open and use by another road, main road is closed, measures very reliable; In addition, owing to using forced seal valve as shutdown valve in the outlet on metering road, to replace traditional partition ball valve, thus in the process of controlled valve, separator can not be made to wear and tear, the phenomenon avoiding valve leak occurs; To sum up, the utility model adopts into sledgeization design, wider to the degree of purity scope of application of gas medium, and to the almost no requirement (NR) of front and back straight length, shortens the size that metering sledge takes up room greatly, can meet more field requirement.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram at mass flowmeter place in the utility model;
In figure: 1, sledge seat 2, metering pipeline 3, entrance cut off ball valve 4, mass flowmeter 5, forced seal valve 6, absolute pressure transmitter 7, integrative temperature transmitter 8, flow transmitter.
[embodiment]
Below in conjunction with accompanying drawing, following further illustrating is done to the utility model:
As shown in Figure 1, the utility model comprises: sledge seat 1, sledge seat 1 is provided with metering pipeline 2, metering pipeline 2 is provided with entrance and cuts off ball valve 3, mass flowmeter 4 and forced seal valve 5, entrance cuts off the inlet end that ball valve 3 is arranged on metering pipeline 2, forced seal valve 5 is arranged on the endpiece of metering pipeline 2, entrance cuts off the inlet end of the endpiece quality of connection flowmeter 4 of ball valve 3, the endpiece of mass flowmeter 4 connects the inlet end of forced seal valve 5, pipeline between mass flowmeter 4 and forced seal valve 5 is provided with absolute pressure transmitter 6 and integrative temperature transmitter 7, the inlet end of the endpiece connecting integration temperature transmitter 7 of absolute pressure transmitter 6, mass flowmeter 4, absolute pressure transmitter 6, integrative temperature transmitter 7 is respectively by connection flow computer.
In the utility model, metering pipeline is provided with two, two metering pipelines comprise metering main line and metering spare duct, metering main line and metering spare duct are installed in parallel on sledge seat, metering main line, metering spare duct are all provided with entrance and cut off ball valve, mass flowmeter, absolute pressure transmitter, integrative temperature transmitter and forced seal valve.Namely the metering system in natural gas station is all generally paired appearance, and a road is used for normal metering as use road, another road is as road for subsequent use, when main road flowmeter breaks down or need to demarcate main road flowmeter time, road for subsequent use is opened and used, main road is closed; Mass flowmeter is provided with flow transmitter 8, as shown in Figure 2, absolute pressure transmitter 6, integrative temperature transmitter 7 are arranged on the pipeline of mass flowmeter endpiece.
This metering system core component mainly comprises mass flowmeter, absolute pressure transmitter, integrative temperature transmitter and flow computer, and wherein, absolute pressure transmitter is used for pressure compensation; Integrative temperature transmitter is used for temperature compensation; Mass flowmeter is used for the flow of measurement gas, to replace traditional ultrasonic flow meter and turbo flow meter; Flow computer, for gathering above-mentioned signal, through calculating, provides instantaneous delivery, integrated flow etc., for Trade Measures.
In the utility model, use forced seal valve as shutdown valve in the outlet on metering road, to replace traditional partition ball valve, its advantage is in the process of controlled valve, separator can not be made to wear and tear, and cause valve leak, can zero leakage be reached, and general ball valve type shutdown valve can not accomplish zero leakage completely.Meanwhile, also just because of there is above advantage, can guarantee that road for subsequent use does not have leakage when the normal work measurement of main road.If because road for subsequent use valve has leakage, and leakage rate does not reach the minimum metered flow requirement of mass flowmeter, mass flowmeter does not measure this part flow, thus this part rock gas leaked can be caused to be fallen by utilization in vain, and the owner of natural gas station does not obtain this part fund dealt with from user there, thus directly cause the economic loss of owner.
The utility model is not by the restriction of above-mentioned embodiment; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
