Abstract
The utility model relates to the technical filed of liquid height measuring, in particular to a blowing device for a frequency modulated continuous wave (FMCW) radar level meter. The blowing device comprises a ball valve and a tee joint, and is characterized in that two sides of an upper valve core of a valve body of the ball valve are provided with an upper inner threaded through hole and a lower inner threaded through hole. The upper inner threaded through hole is connected with an upper quick coupler, and the lower inner threaded through hole is connected with a lower quick coupler. The upper quick coupler and the lower quick coupler are respectively connected with an upper meter air pipe and a lower meter air pipe, and the upper meter air pipe and the lower meter air pipe are connected with the tee joint. When the blowing device is used, an upper flange on the ball valve is connected with the FMCW radar level meter, and a lower flange on the ball valve is connected with a container containing detected liquid. The blowing device is additionally arranged between the FMCW radar level meter and the container. The blowing device for the FMCW radar level meter is suitable for the technical field of liquid level measuring, and particularly suitable for liquid level measuring of liquid in a slightly positive pressure environment.
Description
Technical field
The utility model relates to the liquid level field of measuring technique, particularly relates to the blowning installation that installs additional when a kind of fmcw radar level meter uses.
Background technology
The liquid level field of measuring technique, the common radar level meter, common radar levelmeter is divided into pulse radar material level meter and CW/FM continuous wave/frequency modulated modulated radar levelmeter (FMCW) at present, the fmcw radar level meters that adopt during the interior circumstance complication of tank more; But in actual use; especially under the pressure-fired environment, measure when containing the liquids position of a large amount of solid matters; the frequent incrustation of fmcw radar level meter antenna position, ponding; cause that to measure inaccurate and measure the wave reflection rate be 0 situation; and be pressure-fired in the tank; can't in time clear up the antenna of radar levelmeter, so that fmcw radar level meter functional reliability reduces greatly.
Thus, the improving of the utility model thoughts defects, the spy concentrates on studies and cooperates repetition test, finally proposes a kind of reasonable in design and effectively improve the utility model of defects.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned shortcoming and provide a kind of make the fmcw radar level meter under the pressure-fired environment high reliability, be difficult for incrustation, ponding and can realize at any time the roll off the production line device of cleaning of radar levelmeter antenna, to satisfy industrial needs.
For solving the problems of the technologies described above the technical solution adopted in the utility model:
The blowning installation that a kind of fmcw radar level meter is used, comprise ball valve, threeway, there are upper internal thread through hole and lower internal thread through hole in the both sides that it is characterized in that described ball valve body upper valve core, upper internal thread through hole connects ready-packaged joint, lower internal thread through hole connects lower ready-packaged joint, described upper ready-packaged joint, lower ready-packaged joint connect respectively instrument air pipe and lower instrument air pipe, and upper instrument air pipe and lower instrument air pipe and threeway are joined.
During use, the upper flange of ball valve is connected with the fmcw radar level meter, lower flange is connected with the container of liquid that dress is surveyed, the blowning installation that the utility model fmcw radar level meter is used is installed between fmcw radar level meter and the container, instrument air respectively enters ball valve from upper ready-packaged joint, upper internal thread through hole and lower instrument air pipe via lower ready-packaged joint, lower internal thread through hole via upper instrument air pipe by threeway.During normal operating conditions, make ball valve be in open mode by joystick, instrument air is in ball valve, form up and down convection current, by the control instrument air pressure, so that instrument air forms isolated pressure-fired sealing gland in ball valve, completely cut off the solid particle and the steam that gush under the pressure-fired environment, greatly reduce the possibility of fmcw radar level meter antenna incrustation, ponding; During abnormal operating state, close instrument air, joystick makes ball valve be in closed condition, positive pressure environment in the fully isolated container, fmcw radar level meter one side is in atmospheric pressure state, and can roll off the production line to the fmcw radar level meter at any time operates and antenna is cleared up.
The blowning installation that the utility model fmcw radar level meter is used is installed simple, greatly reduce radar levelmeter antenna incrustation, ponding possibility, and can realize at any time the radar levelmeter antenna being cleared up under the pressure-fired environment, greatly improve the reliability that the fmcw radar level meter is measured, and sound assurance maintenance personal's safety.
The utility model is applicable to the level gauging technical field, is particularly useful for liquid level measurement under the pressure-fired environment.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Embodiment:
As shown in drawings, the blowning installation that the utility model fmcw radar level meter is used, comprise ball valve 1, threeway 11, the upper flange 2 of ball valve 1 is connected with the fmcw radar level meter, lower flange 3 is connected with container, upper ready-packaged joint 6 is connected with upper internal thread through hole 8, and lower ready-packaged joint 5 is connected with lower internal thread through hole 7, and an end of upper instrument air pipe 9 and lower instrument air pipe 10 is connected with upper ready-packaged joint 6, lower ready-packaged joint 5 respectively, another termination threeway 11, handle 4 is used for the break-make of control ball valve 1.
Instrument air is by threeway 11, enters respectively in the ball valve 1 from upper ready-packaged joint 6, upper internal thread through hole 8 and lower instrument air pipe 10 and lower ready-packaged joint 5, lower internal thread through hole 7 via upper instrument air pipe 9.During normal operating conditions, make ball valve 1 be in open mode by joystick 4, instrument air is in ball valve 1, form up and down convection current, by the control instrument air pressure, so that instrument air is in ball valve 1 interior formation pressure-fired sealing gland, the solid particle and the steam that gush under the isolated pressure-fired environment reduce the possibility of fmcw radar level meter antenna incrustation, ponding greatly; During abnormal operating state, close instrument air, joystick 4 makes ball valve 1 be in closed condition, positive pressure environment in the fully isolated container, one side of fmcw radar level meter is in atmospheric pressure state, and can roll off the production line to the fmcw radar level meter at any time operates and antenna is cleared up.
