Abstract
The utility model relates to a special valve control connecting pipe for a gas control box with a built-in valve in a flowmeter. The special valve control connecting pipe comprises a box body, wherein an air intake pipe is communicated with the inlet of a filter, the outlet of the filter is communicated with the inlet of a gas roots flowmeter through a connecting pipe, the outlet of the gas roots flowmeter is communicated with the inlet of an air escape pipe, a pressure gauge is mounted on the connecting pipe, the gas roots flowmeter is connected to a controller through a flow rate data cable, a valve used for adjusting the gas flow rate is arranged in the connecting pipe, and the valve is connected with the signal output end of the controller through the data cable and controls the flow rate or the on/off of the valve through the controller. The utility model has the advantages that the design of the built-in valve in the connecting pipe has the characteristics of compact integral structure, less possibility of human damage, and good control effect; and the utility model realizes the wireless remote-transmission control, greatly improves the metering reliability and safety of a gas metering box.
Description
Technical field
The utility model relates to a kind of combustion gas control box special service valve control connecting pipe valve-embedded in flowmeter, belongs to flow and takes 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 combustion gas control box special service valve control connecting pipe of gas circuit again.
Design proposal: in order to realize above-mentioned purpose of design.Connecting pipe is built-in with valve and is used for the design of pilot-gas rotz flowmeter flow size, is technology principal character 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.
Technical scheme: combustion gas control box special service valve control connecting pipe, it comprises connecting pipe, described connecting pipe is built-in with valve and is used for the flow size of pilot-gas rotz flowmeter.
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 connecting pipe.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.Combustion gas control box special service valve control connecting pipe, it comprises connecting pipe 4, described connecting pipe 4 is built-in with valve 6 and is used for the flow size of pilot-gas rotz flowmeter, 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 the tube wall of connecting pipe 4, and this stepping valve 6 is charged unlatching, the design of outage automatic close-type.Tensimeter 2 is installed on the connecting pipe 4.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 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.
