Description
Technical field
The utility model relates to the flow measurement field, specifically is a kind of integrated vortex shedding flow meter.
Background technology
Chinese patent literature CN2537963Y discloses a kind of " intelligent gas flowmeter ", is provided with flow sensor, pressure transducer and temperature sensor on the table body, and the table body is connected with intelligent integral-counting instrument by the signal wire in pole and the pipe.This flowmeter has realized that three amount one detect, but following deficiency is arranged: the one, and the pressure detection passage exists the high temperature gas flow impact to bring the risk of harm; Two is three sensor triangularities, and distributing looses makes troubles for manufacturing and installation.
Summary of the invention
The utility model technical issues that need to address are to increase technical pattern in the pressure detection passage, to improve the protection to pressure transducer; Merge the installation site of sensor, simplify its installation and maintenance.
Integrated vortex shedding flow meter of the present utility model has a table body, in the sensor storehouse on it flow sensor is housed, and the table body is connected with intelligent integral-counting instrument by the signal wire in pole and the pipe; Also has the pressure detection passage between table body and the intelligent integral-counting instrument, it is characterized in that described pressure detection passage is, be communicated with the pilot condenser pipe of band aqua seal section on the table body, between pilot condenser pipe and the intelligent integral-counting instrument pressure transducer be housed, the signal wire of pressure transducer is connected with intelligent integral-counting instrument.In the structure that the pilot condenser pipe is established aqua seal section, the part that can agglutinate steam water is to slow down high-temperature steam or gas percussion causes damage to pressure transducer.
The aqua seal section of pilot condenser pipe can be U-bend (being equivalent to 180 °), and as preferably, the aqua seal section of pilot condenser pipe is 540 ° a coil pipe, makes the protecting against shock better effects if.
As preferably, between pilot condenser pipe and the pressure transducer valve is installed.Make this passage have break-make control, increased protection pressure transducer etc.
As preferably, in the sensor storehouse of table body second bin level is arranged, be provided with temperature sensor, its signal wire is connected with intelligent integral-counting instrument.The setting of second bin level is not only concentrated but also independently of one another two sensors, has made things convenient for installation and maintenance.
As preferably, valve is fixed on the pole by clamping bar, then can make pressure detection passage and flowmeter more firm.
As preferably, the 3rd interface arranged at the intelligent integral-counting instrument bottom, for the data output or the Long-distance Control of intelligent integral-counting instrument provides convenience.
Three kinds of sensors of the present utility model, intelligent integral-counting instrument is the commercially available prod.
The utility model is simple and compact for structure, not only pressure transducer is had better protect, and is also easy to install.
