Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The split vortex shedding flowmeter shown in fig. 1 comprises a display instrument 1 and a medium channel 2, and the display instrument has the same purpose and structure as those of the display instrument in the prior art. The medium channel is used for circulating gas or liquid medium.
The lower extreme of display instrument 1 is fixed with connector 3, and the connector is used for bending the calibrator and display instrument fixed connection, makes bending calibrator and display instrument can fix together. The upper end of the medium channel is integrally formed with a fixed base 4; a detection hole is formed in the middle of the fixed base and communicated with the medium channel; the fixed base is spirally connected with a connecting seat 5, and the connecting seat are fixedly connected through a bending shaping pipe 6; make the connecting seat, bend the design pipe, connector and display instrument and fix together to can follow unable adjustment base through the screw thread and dismantle, realize the components of a whole that can function independently of flowmeter, can change the display instrument many times on the medium passageway that has installed, with the change number of times that reduces medium passageway, reduce the maintenance complexity, increase of service life.
The bending and shaping pipe 6 is a shaping coil pipe, and the outer diameter of a pipe body of the bending and shaping pipe is 1-2 cm. The design snake is often used for the lazy people's support of cell-phone among the daily life, has fine bending nature and design nature to have the support performance. The utility model discloses in can support display instrument on the one hand, on the other hand can carry out the bending of multiple angle with the multiple place of adaptation to it as required. Furthermore, the utility model discloses the pipe shaft external diameter that uses will be greater than prior art's external diameter, can more accord with the utility model discloses, thicker pipe shaft has stronger holding power, enough support to display instrument.
The inside of connecting seat 5 is provided with flow sensor 7, and flow sensor's probe 8 stretches out in the exploration hole, makes flow sensor's probe can stretch into and survey the flow in the medium passageway. And because flow sensor installs in the connecting seat, will take together flow detector and display instrument to dismantle when changing, overhaul or change.
The flow sensor is fixed at the lower end of the fixed block 9; the fixed block is fixedly connected with the connecting seat, and the upper end of the fixed block is fixedly connected with a first protection frame 10; the middle parts of the first protection frame and the fixed block are provided with accommodating cavities which are communicated with each other, and wires 11 are accommodated in the accommodating cavities; the first protection frame 10 and the wire are in interference fit by winding a rubber sealing ring on the wire. The fixed block has the effects that on one hand, the flow sensor is fixed in the connecting seat, and the specific fixed connection mode can be selected according to the actual situation; another aspect is that the middle portion forms a cavity for receiving the wire.
Because the shaping pipe of bending can carry out the bending of different angles according to actual need, consequently will drive its inside wire and buckle thereupon, in order to prevent that the wire from buckling the in-process and splitting with flow sensor's joint department to set up a protecting frame. The upper end that the protective frame can the shutoff connecting seat to can fix the wire with wire interference fit and can not move in disorder, with the wire position stability of guaranteeing the flow sensor top, thereby the coupling part between protection wire and the flow sensor is not fragile. For example, the connecting part of cell-phone charging wire and plug because the bending of different degree, different angles can appear in the use of charging wire, consequently the wire fracture often can appear in the junction, and consequently the normal use of flowmeter can be guaranteed to the bearer bar, guarantees that the wire of flow sensor top is motionless, makes the difficult fracture of wire of junction.
