Abstract
The invention provides a turning plate type air speed switch which comprises a shell, an overturning shaft, a turning plate and a position switch, wherein the overturning shaft is fixed at the upper part of the interior of the shell; the turning plate is connected on the overturning shaft and can rotate around the overturning shaft; the position switch is arranged at the air out end and downwards extends into the shell; and a sensor is arranged at the bottom of the position switch extending into the shell. According to the turning plate type air speed switch, the position switch is used for detecting the overturning angle of the turning plate; when air currents are input into the shell, the air currents act on the turning plate to generate pressure so that the turning plate moves along the overturning shaft; when the velocity of air currents reaches a specific valve, the turning plate rotates to justly touch the position switch and trigger the sensor to send out electrical signals; when wind force is less than the specific value, the turning plate can not touch the position switch, the sensor can not detect the metal turning plate and stops sending out the electric signals, thereby the function of an air speed switch is obtained.
Description
Technical field
The present invention 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.
Summary of the invention
The object of the invention 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 present invention 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 distance of the height of described turnover panel and trip shaft to position switch is suitable, 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 invention detects the turnover panel flip angle through 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 sketch map of turnover plate type Wind speed switch of the present invention.
Embodiment
Fig. 1 is a most preferred embodiment of the present invention, the invention is not restricted to present embodiment.
Referring to Fig. 1, turnover plate type Wind speed switch of the present invention 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 of the turnover panel 3 among the present invention and the distance of trip shaft 2 to position switch 4 are suitable, and turnover panel can turn to the transducer conflict and links to each other.
Housing 1 among the present invention is pipe, square tube or polygon pipe.
Operation principle of the present invention 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.
