Abstract
The utility model relates to a valve control gas roots flowmeter in which a valve is arranged. The valve control gas roots flowmeter comprises a gas roots flowmeter, and the gas roots flowmeter is internally provided with the valve used for controlling the flow rate of the gas roots flowmeter. The valve control gas roots flowmeter has the advantages of: firstly, not only compact whole structure but also little possibility of being damaged artificially and good control effect by the design that the gas roots flowmeter is internally provided with the valve; and secondly, realization of wireless remote transmission control and immense improvement of the metering reliability and safety of a gas metering tank.
Description
Technical field
The utility model relates to a kind of valve control gas roots flowmeter valve-embedded in flowmeter, belongs to flowmeter and makes the 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 valve control gas roots flowmeter of gas circuit again.Design proposal: in order to realize above-mentioned purpose of design.Gas roots flowmeter 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 gas roots flowmeter 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.
Technical scheme: valve control gas roots flowmeter, it comprises gas roots flowmeter, the stepping by-pass valve control is installed by described gas roots flowmeter inflow point.
Described valve is the step motor control valve and controls its flow size and open and close by control line by controller.
The utility model is compared with background technology, and the one, the built-in valvular design of gas roots flowmeter, 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 gas roots flowmeter.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.Valve control gas roots flowmeter, it comprises gas roots flowmeter 5, described gas roots flowmeter 5 inflow points install stepping by-pass valve control 6 and are used for the flow size of pilot-gas rotz flowmeter 5, that is to say, in gas roots flowmeter 5 inflow points 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 gas turbine 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.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just mentality of designing simple text of the present utility model is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed in the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. valve control gas roots flowmeter, it comprises gas roots flowmeter, it is characterized in that: the stepping by-pass valve control is installed by described gas roots flowmeter inflow point.
2. valve control gas roots flowmeter according to claim 1 is characterized in that: described valve is the step motor control valve and controls its flow size and open and close by control line by controller.
