Description
Technical field
The utility model relates to a kind of wireless remote transmission gas roots flowmeter measuring tank that valve is set in the special-purpose connecting pipe of combustion gas control box, belong to flow and take into account flowmeter control box manufacturing field.
Background technology
All Granted publication CN100478653C of the applicant, title " gauging box of Roots gas flowmeter ", be positioned at the filtrator gas outlet of casing and Roots and show air intake opening and be communicated with by connecting leg, the air intake opening of filtrator and Roots show the gas outlet and are communicated with and the interface of valve inlet, outlet is positioned at outside the casing gas outlet of the air intake opening by valve and filtrator and Roots's table respectively.Its weak point: the one, valve is external manual structure, can't realize wireless remote transmission control; The 2nd, under abnomal condition, can't realize closing gas circuit automatically, there is potential safety hazard.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of wireless remote transmission of can either realizing and control, can under abnomal condition, realize closing automatically the wireless remote transmission gas roots flowmeter measuring tank of gas circuit again.
Design proposal: in order to realize above-mentioned purpose of design.1, connecting pipe is built-in with valve and is used for the design of pilot-gas rotz flowmeter flow size, is one of technical characterictic of the present utility model.The purpose of doing like this is: the one, can realize that the stepping by-pass valve control of control is built in the connecting pipe automatically, compact conformation not only, and be not subject to artificial destruction, the more important thing is instruction that it can send according to controller Open valve or valve-off reliably.2, adopting the design of the wireless remote transmission gas roots flowmeter measuring tank of connecting pipe formation, is two of technical characterictic of the present utility model.Such purpose is: the one, when combustion gas is popped one's head in detected combustable gas concentration when surpassing setting value, controller directly cuts out by the valve in the data line instruction connecting pipe, when combustion gas is popped one's head in detected combustable gas concentration when being lower than setting value, controller is by the valve opening in the data line instruction connecting pipe, but, when the detected once more combustable gas concentration of combustion gas probe surpasses setting value, controller directly cuts out and Locking valve by the valve in the data line instruction connecting pipe, overhaul until operating personnel, after resetting, valve in the connecting pipe normal operating conditions of being allowed for access, realize double insurance metering air feed, fundamentally guaranteed the reliability and the security of the metering of gas metering case.When (2) earthquake magnitude that detects when inductive probe surpasses setting value, controller directly cuts out by the valve in the signal wire instruction connecting pipe, after earthquake magnitude is eliminated, after operating personnel's maintenance, resetting, valve in the valve control rotz flowmeter normal operating conditions of being allowed for access, when having guaranteed that earthquake takes place, the reliability and the security of the metering of back combustion gas batch meter take place.
Technical scheme: the wireless remote transmission gas roots flowmeter measuring tank that constitutes by combustion gas control box special service valve control connecting pipe, it comprises casing, draft tube is communicated with filter inlet, filter outlet is communicated with the gas roots flowmeter import by connecting pipe, the gas roots flowmeter outlet is communicated with the escape pipe import, and tensimeter is installed on the connecting pipe, gas roots flowmeter by data on flows by data line to controller, described connecting pipe is built-in with valve and is used for the size of gas flow, and valve is connected with the signal output part of controller by data line and the big or small or pass by the flow of controller by-pass valve control, or open.
The utility model is compared with background technology, and the one, the built-in valvular design of connecting pipe, compact overall structure not only, and be difficult for being controlled effective by artificial destruction; The 2nd, realized wireless remote transmission control, greatly improved the reliability and the security of gas metering case metering.
Description of drawings
Fig. 1 is the structural representation of wireless remote transmission gas roots flowmeter measuring tank.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The wireless remote transmission gas roots flowmeter measuring tank that constitutes by combustion gas control box special service valve control connecting pipe, it comprises casing, draft tube is communicated with gas roots flowmeter 1 import, gas roots flowmeter 1 outlet is communicated with tensimeter 2 imports, tensimeter 2 outlets are communicated with gas roots flowmeter 5 imports by connecting pipe 4, gas roots flowmeter 5 outlets are communicated with the escape pipe import, gas roots flowmeter 5 by data on flows by data line to controller, described connecting pipe 4 is built-in with valve 6 and is used for the size of gas flow, and valve 6 is connected with the signal output part of controller 10 by data line and the big or small or pass by the flow of controller by-pass valve control 6, or open.Described casing is built-in with combustion gas leakage alarm 8 and is connected with controller 10 signal input parts by data line, and directly drives buzzer warning and close the interior valve 6 of connecting pipe.The built-in thoughts of described casing are shaken device 7 and are connected by the signal input part of data line with controller 10, and controller 10 opens or closes according to the valve 6 in the earthquake magnitude information command connecting pipe of being gathered.Described controller is the IC-card display controller, controller is installed on the casing shop front, and controller can show the remaining sum (or surplus) in operating mode, mark condition cumulative flow value, instantaneous delivery value, temperature value, force value and the IC-card of gas roots flowmeter and the opening and closing state of valve.Have IC-card card inserting mouth and battery compartment on the display controller, when battery electric quantity is not enough, can display alarm remind the user in time to change battery, in order to avoid valve cuts off automatically because of electric weight is not enough.Maybe when Sorry, your ticket has not enough value in the card, can display alarm remind the user in time to supplement with money, in order to avoid valve cuts off automatically because of Sorry, your ticket has not enough value.All data in the optional logic encryption card of the IC-card of adapted, CPU card (e-credit), the non-contact card, controller can adopt the wireless remote transmission mode, need not cabling and both can realize data remote.This valve embedding structure and flow show and the structure of control one has realized real integrated design, make its design level reach a new height.Described connecting pipe 4 is built-in with valve 6 and is used for the flow size of pilot-gas rotz flowmeter 5, that is to say, in connecting pipe 4 pipes stepping by-pass valve control 6 is installed, the data line that is used for control step valve 6 is drawn by gas roots flowmeter 5 upper end covers, and this stepping valve 6 is charged unlatching, the design of outage automatic close-type.Described gas roots flowmeter can substitute with the worm gear gas meter.Described valve 6 is controlled its flow size and open and close for the step motor control valve and by control line 13 by controller.11 is the tensimeter view window.
