Abstract
The utility model relates to an automatic switch nozzle cover for an air flow nozzle, mainly comprising parts such as an electric actuator (1), a bracket (2), a movable rod (3), a cover plate (4) and an air bag (5) and the like, wherein the electric actuator (1) is in angle stroke type, and can drive the movable rod (3) to rotate by 90 degrees after control signals are input from the outside of a measuring box; a cover plate (4) and the air bag (5) which are both at the top end of the movable rod (3) are rotated to horizontal positions from an outlet position of the air flow nozzle (6); and the movable rod (3) is rotated reversely by 90 degrees, and the cover plate (4) and the air bag (5) rotates back to the outlet positions of the air flow nozzle (6) from the horizontal positions. At the moment, an outlet of the air flow nozzle (6) is sealed by the air bag (5), therefore, the purpose of automatically opening and closing the air flow nozzle (6) by a remote control mode is achieved.
Description
Affiliated technical field
The utility model relates to a kind of air mass flow nozzle automatic switch nozzle cover, the particularly a kind of automatic switch nozzle cover that can realize Long-distance Control.
Background technology
Manual type is all adopted in the opening and closing of air mass flow nozzle in the past.In the air-flow measurement case that is lumped together by several air mass flow nozzle sets, in measuring process, when some air mass flow nozzles need be opened or close, the nozzle cover in its outlet was all struck with the hand by operating personnel and opens or closes.Technical specification according to air-flow measurement, in the process of measuring, require the measurement state should keep continuity and stability as far as possible, if adopt the opening and closing of manual type manipulating nozzles lid, then must in measuring process, open the measurement chamber door, this has just caused abnormal interference to measuring process, has also reduced the operating efficiency of measuring.To a measuring system that the automatic data collection functional requirement is arranged, with the opening and closing of manual type manipulating nozzles lid, the automatic conversion that also can't realize measuring operating mode.
Summary of the invention
In order to solve the problem that existing air mass flow nozzle can not open and close automatically, the utility model provides a kind of automatic switch nozzle cover, and this nozzle cover not only can open and close automatically, and can realize Long-distance Control.
The purpose of this utility model is to adopt the mode of Long-distance Control, from measuring the outside input control signal of case, drive the unlatching of nozzle cover or close by YE, thereby avoided in measuring process, opening the adverse effect that the measurement chamber door causes measuring process, also improve the operating efficiency of measuring, solved the automatic transfer problem of the measurement operating mode of automatic data collection measuring system simultaneously.
The purpose of this utility model realizes by following technical scheme:
The automatic switch nozzle cover mainly is made up of parts such as YE, support, motion bar, cover plate and air bags, and wherein, YE is an angle stroke pattern.The automatic switch nozzle cover that assembles is installed on the air mass flow nozzle fixed head.When some air mass flow nozzles is opened or closed to needs, from measuring the case outside to the YE input control signal, make YE drive the motion bar half-twist of nozzle cover, the cover plate on motion bar top and air bag rotate to horizontal level by the exit position of air mass flow nozzle, or rotate back to the exit position of air mass flow nozzle, thereby realize opening and closing automatically the purpose of air mass flow nozzle by horizontal level.
The utility model is owing to adopted the Long-distance Control mode, and technology such as YE and air bag, has solved the problem that air mass flow nozzle in the past can not be opened automatically or close.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the front view of structural representation of the present utility model; Fig. 2 is the left view of structural representation of the present utility model.
1. YEs among the figure, 2. support, 3. motion bar, 4. cover plate, 5. air bag, 6. air mass flow nozzle, 7. air mass flow nozzle fixed head.
The specific embodiment
In the drawings, YE [1] is an angle stroke pattern, and it links to each other with motion bar [3], and is installed on the air mass flow nozzle fixed head [7] with support [2].There is cover plate [4] on the top of motion bar [3], and cover plate [4] has air bag [5] on the one side of air mass flow nozzle [6], the dome shape of air bag [5] inflation back for heaving.When needs are opened air mass flow nozzle [6], from measuring the case outside to YE [1] input control signal, make YE [1] drive motion bar [3] half-twist, the cover plate [4] on motion bar [3] top and air bag [5] rotate to horizontal level by the exit position of air mass flow nozzle [6].When needs are closed air mass flow nozzle [6], from measuring the case outside to YE [1] input control signal, make YE [1] drive 90 ° of motion bar [3] reverse rotations, the cover plate [4] on motion bar [3] top and air bag [5] are rotated back to the exit position of air mass flow nozzle [6] by horizontal level, this moment, the air bag [5] on motion bar [3] top closed the outlet of air mass flow nozzle [6], thereby realized opening and closing automatically the purpose of air mass flow nozzle [6].
Claims (3)
1. air mass flow nozzle automatic switch nozzle cover, mainly form by YE [1], support [2], motion bar [3], cover plate [4] and air bag [5] etc., it is characterized in that described YE [1] is angle stroke pattern, can drive motion bar [3] half-twist behind the input control signal, rotate to horizontal level by the exit position of air mass flow nozzle [6]; Or 90 ° of reverse rotations, rotate back to the exit position of air mass flow nozzle [6] by horizontal level.
2. air mass flow nozzle automatic switch nozzle cover as claimed in claim 1 is characterized in that there is cover plate [4] on the top of described motion bar [3], and cover plate [4] has air bag [5] on the one side of air mass flow nozzle [6].
3. air mass flow nozzle automatic switch nozzle cover as claimed in claim 1 is characterized in that the dome shape of air bag [5] inflation back for heaving.
