Abstract
The utility model discloses an electric-quantity-outputting type glass rotameter which comprises bases, an encloser and a cone-shaped glass tube, the encloser is installed between the two bases, the cone-shaped glass tube is installed in the encloser, a floater is installed in the cone-shpaed glass tube, a bijection type optoelectronic switch is installed on the encloser and is composed of a transmitter and a receiver, the transmitter and the receiver are installed on the two sides of the encloser, and the positions of the transmitter and the receiver correspond to the position of the floater. When a flow rate changes, switching signals can be output to connect a warning device, a worker can find the change of the flow rate in time, and bad consequences are prevented from occurring.
Description
Technical field
The utility model relates to a kind of flowmeter, relates in particular to a kind of electric weight output type glass rotameter.
Background technology
At present, the main measuring sensor of known glass rotameter is a vertical transparent Taper Pipe and at the interior float that can move up and down, the fluid Taper Pipe of flowing through from bottom to top during work, and the equilibrium position of float can indicate measuring of flow.But this flowmeter only can be indicated flow, can not export electric quantity signal to drive warning device when flow changes, and in unattended place, the variation of flow can not be found timely, so that produced adverse consequences.
Summary of the invention
The purpose of this utility model provides a kind of electric weight output type glass rotameter, can export the switching value signal when flow changes, and is connected to can control warning device in the external circuit and send alerting signal.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of electric weight output type glass rotameter, comprise pedestal, case, tapered glass tube, between two pedestals case is installed, case is installed tapered glass tube, it is characterized in that: float is installed in the tapered glass tube, the correlation optoelectronic switch is installed on the case, the correlation optoelectronic switch is made up of transmitter and receiver, transmitter and receiver are installed in the both sides of case respectively, and transmitter is corresponding with the position of float with receiver.
According to described electric weight output type glass rotameter, it is characterized in that: described case center is opened a rectangle hole along the vertical direction, length can cover most of scale, width is the diameter of optoelectronic switch, the both sides of case are provided with opening, and transmitter and receiver are installed in respectively on the opening of case both sides.
The utility model has the advantages of and be: can when flow changes, connect warning device by output switching signal, allow the staff in time find the variation of flow, avoid producing adverse consequences.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawing: 1, pedestal; 2, case; 3, tapered glass tube; 4, float; 5, transmitter; 6, receiver.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of electric weight output type glass rotameter, comprise pedestal 1, case 2, tapered glass tube 3, case 2 is installed between two pedestals 1, and case 2 is installed tapered glass tube 3, it is characterized in that: float 4 is installed in the tapered glass tube 3, the correlation optoelectronic switch is installed on the case 2, the correlation optoelectronic switch is made up of transmitter 5 and receiver 6, and transmitter 5 and receiver 6 are installed in the both sides of case 2 respectively, and transmitter 5 is corresponding with the position of float 4 with receiver 6.According to described electric weight output type glass rotameter, it is characterized in that: described case 2 centers are opened a rectangle hole along the vertical direction, length can cover most of scale, width is the diameter of optoelectronic switch, the both sides of case 2 are provided with opening, and transmitter 5 and receiver 6 are installed in respectively on the opening of case 2 both sides.
Use principle of the present utility model as shown in Figure 1, the correlation optoelectronic switch is overlapped over against the equilibrium position installing one of float 4 in tapered glass tube 3 outsides at flowmeter, optoelectronic switch is made up of transmitter 5 and receiver 6, and transmitter 5 and receiver 6 place the both sides, equilibrium position of float 4 respectively and be fixed on the case 2.When the normal condition down-off was stablized, float 4 was stable on a certain scale, and the light that transmitter 5 sends is blocked by float 4, at this moment the optoelectronic switch output switching signal.When flow changed consequently float 4 generation displacements, the light that transmitter 5 sends was not blocked by float and is directly entered receiver 6, and then the switching signal of optoelectronic switch output changes, and makes external circuit connect warning device and sends alerting signal.On the case 2 of glass rotameter both sides, open a rectangle hole along the vertical direction in the center, length can cover most of scale, width is the diameter of optoelectronic switch, the transmitter 5 of optoelectronic switch and receiver 6 are installed in respectively on the opening of both sides case 2, and can move up and down along glass conical tube, be fixed in needed scale position.During operate as normal, float must be between the transmitter of optoelectronic switch and the receiver and can block light.Optoelectronic switch is connected in the external circuit, is used for the control warning device.Can when flow changes, connect warning device by output switching signal, allow the staff in time find the variation of flow, avoid producing adverse consequences.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; common engineering technical personnel make the technical solution of the utility model in this area various modification and improvement all should fall into protection domain of the present utility model.
