Abstract
The utility model relates to the field of manufacturing of natural gas recording instruments, particularly to a natural gas flow compensator. Thenatural gas flow compensator comprises a pressure detector, a PLC (programmable logic controller) industrial personal computer, a solenoid valve, an electric valve and a natural gas flowmeter, wherein the pressure detector is connected with a gas storage bag; the PLC industrial personal computer is in signal connection with the pressure detector; the solenoid valve, theelectric valve and the natural gas flowmeter are mounted on a gas delivery pipeline, and both the solenoid valve and theelectric valve are in signal connection with the PLC industrial personal computer. With the adoption of the natural gas flow compensator, the measurement precision of the natural gas flowmeter is greatly improved, and the problem of excessive readings is effectively solved.
Description
Technical field
The utility model relates to natural gas register instrument and makes field, relates in particular to a kind of gas discharge compensator that can linear regulation.
Background technology
Because natural gas flowmeter is when the calibrational capacity precision, be at constant voltage, constant flow, constant temperature, the long-time flow of measuring in the prior art, and in actual applications, may have a lot of natural gas facilities and can adopt as pulse controlled mode and control.Pulse pulpit is to carry out regulating impulse width according to temperature control signals, during formation, open, time the process of closing, this and natural gas flowmeter do not mate very much.The rotor of natural gas flowmeter is under the prerequisite running up, pulse is controlled and natural gas valve to be cut off, but in without flow situation, flowmeter can also remain in operation under the effect of inertia, make the reading of natural gas flowmeter be greater than actual use traffic, many reaches 1.7 times.Cause deviation of reading larger, customers' responsiveness is more undesirable.
Summary of the invention
The utility model is for the deficiencies in the prior art, provide a kind of can linear regulation natural gas flow, effectively prevent pulse control the valve producing and cut off after flowmeter remain in operation and cause reading to have gas discharge compensator and the using method thereof of larger error.
The utility model is for solving the problems of the technologies described above, provide following technical scheme: gas discharge compensator, it is characterized in that comprising with gas storage bag Bonding pressure detecting device, the PLC industrial computer being connected with pressure detector signal and be installed on solenoid valve, motorized valve, the natural gas flowmeter on gas pipe line, described solenoid valve, motorized valve are all connected with PLC industrial computer signal.
A gas discharge compensator using method, comprises the following steps: when gas equipment starts to use gas, gas storage bag sets force value; The variation of gas storage bag pressure power is transferred to industrial computer PLC by pressure detector by pressure signal, by PLC output 4～20mA current signal, to step-less adjustment valve, control gas discharge, when being greater than natural gas flowmeter minimum value, solenoid valve is opened, flowmeter is started working, when gas storage bag pressure power approaches setting value, motorized valve can open or cut out by auto linear, makes natural gas flowmeter obtain linear regulation, to reduce the inertia of flowmeter, guarantee that flowmeter metering is more accurate.
The beneficial effects of the utility model: the utility model has improved natural gas flowmeter measuring accuracy greatly, effectively prevent reading problems of too.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Gas discharge compensator, comprise with gas storage bag 001 Bonding pressure detecting device 002, the PLC industrial computer 003 being connected with pressure detector 002 signal and be installed on solenoid valve 005, motorized valve 006, the natural gas flowmeter 007 on gas pipe line 004, described solenoid valve 005, motorized valve 006 are all connected with PLC industrial computer 003 signal.
A gas discharge compensator using method, comprises the following steps: when gas equipment starts to use gas, gas storage bag 001 sets force value; The 001 pressure variation of gas storage bag is transferred to PLC industrial computer 003 by pressure detector 002 by pressure signal, by PLC output 4～20mA current signal, to motorized valve 006, control gas discharge, when being greater than natural gas flowmeter 007 minimum value, solenoid valve 005 is opened, flowmeter 007 is started working, when gas storage bag 001 pressure approaches setting value, motorized valve 006 can open or cut out by auto linear, make natural gas flowmeter 007 obtain linear regulation, to reduce the inertia of flowmeter 007, guarantee that flowmeter 007 metering is more accurate.
Illustrate: natural gas flowmeter 007 has maximal value and minimum value when detecting flow, being less than minimum value flowmeter 007 does not just measure, be greater than maximal value flowmeter 007 reading also inaccurate, the pressure of setting according to gas storage bag 001, when motorized valve 006 is opened to while being greater than flowmeter minimum value, solenoid valve 005 is opened automatically, according to consumption adjusting size.When being greater than rock gas maximum flow, electromagnetic valve for natural gas 005 is closed.
The effect of step-less adjustment: gas storage bag 001 step-less adjustment.In adjustment process, play from small to large, from big to small, Linear Control effect.Make natural gas flowmeter 007 and motorized valve 006 play synchronous effect, to reduce the inertia effect of flowmeter 007 rotor.
The effect of gas storage bag 001: rock gas gas equipment and flowmeter 007 play buffer action.
