A light reflecting room is arranged in the housing wall, and a reflecting ring is arranged in the light reflecting room connected with one end of a transmitting fiber and one end of a receiving fiber; the other ends of the transmitting fiber and the receiving fiber are connected with a peripheral photoelectric conversion device. Accordingly, the utility model has the advantages of simple installation, compact structure, reliable performance and long service life.
Description
Invention field
The utility model relates to a kind of sensor of detector switch valve state, relates in particular to a kind of Fibre Optical Sensor that is used to detect Direct Travel cylinder valve state.
Background technology
In a lot of industries, the flow direction of medium is controlled by valve, therefore the state-detection of valve is to be indispensable in the automatic control of fluid, especially in the Direct Travel cylinder valve, the state issues of valve is even more important, concerning in the entire work process control to this fluid of air, and the flow of air is particularly important to the work of entire cylinder, under the prior art, the information transmitter that much is used for the Direct Travel cylinder valve is arranged, as mechanical contact-type, the magnetic reed switch formula, electromagnetic type or the like, but because the information transmitter of mechanical contact-type is because poorly sealed, cause gas leakage, leak, the result can cause contact erosion, loose contact; And the magnetic reed switch formula because the device unreliability, cause the flase drop wrong report through regular meeting.
Goal of the invention
The purpose of this utility model has in the deficiency that overcomes above-mentioned technology, provide a kind of install simple, structure is small and exquisite, the optical fiber information transmitter that is used for the Direct Travel cylinder valve of dependable performance, long service life.
Technical scheme
The technical solution of the utility model can realize by following manner: the optical fiber information transmitter of this Direct Travel cylinder valve, comprise the push rod and sleeve that is arranged on the cylinder, and the sleeve upper end is arranged with one
The shape shell, the magnet that is provided with push rod in the sleeve and is set in the spring on the push rod and is arranged at the push rod end, in shell wall, be provided with the light reflection room, one tore of reflection is placed in the light reflection room, reflection room links to each other with an end that receives optical fiber with launching fiber, and launching fiber links to each other with the photoelectric conversion device of a peripheral hardware with the other end that receives optical fiber.
Described smooth reflection room is one to be arranged at the ring cavity in the shell wall, and its inwall is a black; Described tore of reflection is a ring-type, is placed in the light reflection room, and its height is less than the chamber height, and this tore of reflection inside surface is smooth, and its material is can be by the metals such as iron of attraction; Described magnet is arranged at the movable end of push rod; Described photoelectric conversion device comprises luminescent device that links to each other with launching fiber and the electrooptical device that links to each other with reception optical fiber; Described optical fiber information transmitter be arranged at up and down two ends of cylinder, both shared photoelectric conversion devices; Described shell and rotatable not removable connection of push rod and sleeve.
Beneficial effect
The beneficial effects of the utility model are:
1. owing to be the setting that matches with ejecting rod of cylinder, install simple;
2. adopt optical fiber as sensor, structure is small and exquisite;
The susceptibility of optical fiber strong and be difficult for impaired, so dependable performance, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a work synoptic diagram of the present utility model.
Fig. 3 is that the utility model is connected the synoptic diagram when being used with cylinder valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is made further instruction.
As shown in Figures 1 to 3, the optical fiber information transmitter that the utility model is used for the Direct Travel cylinder valve comprises the push rod and sleeve 2 that is arranged on the cylinder 1, and sleeve 2 upper ends are arranged with one
Shape shell 3, the magnet 6 that is provided with push rod 4 in the push rod and sleeve 2 and is set in the spring 5 on the push rod 4 and is arranged at the push rod end, in shell wall, be provided with light reflection room 7, one tore of reflection 72 is placed in the light reflection room, reflection room links to each other with an end that receives optical fiber 76 with launching fiber 74, and launching fiber 74 links to each other with the photoelectric conversion device 8 of a peripheral hardware with the other end that receives optical fiber 76; When valve 10 is opened; piston 12 in the cylinder 1 moves up; the push rod 4 of upper end information transmitter is near piston 12; as shown in Figure 2; push rod 4 is pushed by piston 12 and moves; spring 5 is compressed; the magnet 6 of push rod movable end moves thereupon; because described tore of reflection 72 is a ring-type; be placed in the light reflection room; and its inside surface is smooth; material is can be by the metals such as iron of attraction because of magneticaction; at this moment; under the effect of magnetic force; the tore of reflection 72 that drives in the reflection room 7 moves; the illumination of sending from launching fiber 74 is mapped on the tore of reflection; and because described optical fiber two ends through polishing; be with the resilient protection pipe in the middle of it; so lightsensitivity is strong, because the outside surface of tore of reflection has light reflective, thereby this part light is reflected to reception optical fiber 76; and through receiving Optical Fiber Transmission in photoelectric conversion device 8; described photoelectric conversion device 8 comprises luminescent device 82 that links to each other with launching fiber and the electrooptical device 84 that links to each other with reception optical fiber, thereby the signal that optical fiber is passed on can convert electric signal at this, and from electric wire 96 outputs.After tore of reflection moves a certain distance with magnet, tore of reflection is blocked by outer casing inner wall, guarantee push rod by on the piston crown time, the emission of launching fiber can shine on the tore of reflection always, and magnet can also continue to move a segment distance, prolonged buffer distance, improved the reliability of information transmitter, when piston leaves push rod, got back to the reflection room bottom because of the return effect of spring makes magnet drive tore of reflection, the be reflected black inwall of chamber of the light of launching fiber absorbs, and guaranteeing does not have reflected light to enter reception optical fiber.In like manner, when piston moved down under compressed-air actuated promotion, with valve closing, the information transmitter of lower end repeated said process near piston, thereby can make down information transmitter detect the state that valve closes.
In sum, this utility model have install simple, structure is small and exquisite, the characteristics of dependable performance and long service life.
