Abstract
The utility model provides a turning board type wind-speed switch. The wind-speed switch comprises a casing, a turnover shaft, a turning board and a position switch, wherein the turnover shaft is fixed at the upper part inside the casing; the turning board is connected with the turnover shaft and can rotate around the turnover shaft; the position switch is arranged at the gas outlet end of the casing and downwardly extends into the casing; and a sensor is mounted at the bottom of the position switch extending into the casing. In the wind-speed switch, the turning angle of the turning board is detected by the position switch; after being input into the casing, airflow acts on the turning board to generate pressure, so that the turning board move along the turnover shaft; after the intensity of airflow reaches a certain value, the turning board rotates to exactly reach the position switch, so that the sensor is triggered to send out an electrical signal; and when the wind power is smaller than a certain value, the turning board can not reach the position switch, the sensor can not detect the metal turning board, and an electrical signal can not be sent any more, so that the function of the wind-speed switch is performed.
Description
Technical field
The utility model relates to Wind speed switch, particularly a kind of turnover plate type Wind speed switch.
Background technology
Wind speed switch is used for general commerce and PECVD machine air cooling system, the Wind speed switch design relative complex of prior art, and the switching threshold adjustable range is less.
The utility model content
The purpose of this utility model in order to solve the problems referred to above that prior art exists, provides a kind of turnover plate type Wind speed switch exactly.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of turnover plate type Wind speed switch, and it comprises:
Housing has the gas passage of a perforation;
Trip shaft is fixed on the top in the housing;
Turnover panel is connected on the trip shaft and also can rotates around trip shaft;
Position switch, the gas outlet end that is arranged on housing also stretches into downwards in the housing, and the bottom of stretching into the position switch in the housing is equipped with transducer;
The height of described turnover panel and trip shaft are suitable to the distance of position switch, and turnover panel can turn to the transducer conflict and links to each other.
Described position switch is selected from a kind of near in switch, optoelectronic switch or the travel switch.
Described housing is pipe, square tube or polygon pipe.
The position of described position switch can up-down adjustment.
Turnover plate type Wind speed switch of the present utility model detects the turnover panel flip angle by position switch.The position of position switch can up-down adjustment.Housing can be an arbitrary shape, and can be connected with various forms with pipeline, and connected mode can be: be threaded, flange connects or plug-in type connects, the connected mode of housing and gas piping can be orthoscopic, right-angle type and other angles.
Description of drawings
Fig. 1 is the basic structure schematic diagram of the utility model turnover plate type Wind speed switch.
Embodiment
Fig. 1 is a most preferred embodiment of the present utility model, and the utility model is not limited to present embodiment.
Referring to Fig. 1, turnover plate type Wind speed switch of the present utility model comprises housing 1, trip shaft 2, turnover panel 3, his position switch 4.Housing 1 has the gas passage of a perforation.Trip shaft 2 is fixed on the top in the housing 1.Turnover panel 3 is a thin slice shape metalwork, is connected on the trip shaft also can rotate around trip shaft.Position switch 4 is arranged on the gas outlet end of housing 1 and stretches into downwards in the housing 1, and the bottom of stretching into the position switch in the housing is equipped with transducer 5.
The height and the trip shaft 2 of the turnover panel 3 in the utility model are suitable to the distance of position switch 4, and turnover panel can turn to the transducer conflict and links to each other.
Housing 1 in the utility model is pipe, square tube or polygon pipe.
Operation principle of the present utility model is that after air-flow was by pipeline input housing, air-flow acted on turnover panel and produces pressure, makes turnover panel move along trip shaft.After the size of air-flow reached a certain particular value, turnover panel turned to and just in time touches position switch, triggered transducer, sent the signal of telecommunication.When wind-force during greater than this fixed value turnover panel continue the touch location switch, make transducer be in signal of telecommunication emission state always.When wind-force is worth less than this, turnover panel can't touch position switch, and transducer can't detect the metal turnover panel will stop to send the signal of telecommunication, thereby play a kind of effect of Wind speed switch.
