Abstract
The utility model discloses a fluid flow monitor, composed of a flow monitor body, a piston and a dry reed pipe. The position of the piston corresponds to the position of the dry reed pipe, the coupling of a magnetic field produced by permanent magnets in the piston can affect the dry reed pipe, and the dry reed pipe can output signals for fluid flow or interruption, so that the state of fluid flow in a pipeline can be accurately judged. The fluid flow monitor of the utility model has the advantages of high sensitivity, simple structure, low cost, convenient installation and debugging, and long service life, being suitable for the fields of chemical industry, petroleum, pharmacy, light industry, etc.
Description
The utility model relates to a kind of flow monitor that is used for the monitor fluid flow state.
At present, the utilizable flow meter is observed fluid and is supplied with and the interruption situation, but it is the isolated plant of side constant flow, can not moment reacting fluid interrupt, also should not adopt in many occasions; From pressure gauge (table), can observe fluid supply situation the pipeline, but when fluid stopped to flow, pressure existed toward contact, be difficult to promptly judge whether that fluid is supplied with or interruption.Whether the supply of fluid is directly connected to the normal operation and the safety of equipment.
The purpose of this utility model provides a kind of fluid flow monitor, and accurately monitoring fluid is supplied with and interrupted.
For achieving the above object, the utility model mainly is made up of flow monitor body, piston and tongue tube, and the fluid ostium and the fluid tap hole of mutual perforation is set on the flow monitor body, the ostium middle part is provided with back-up ring, the back-up ring leading portion is an inflow entrance, and the back-up ring back segment is a cylinder barrel, and the cylinder barrel front end is a back-moving spring, the rear end is a piston, the piston stage casing has groove, and the back segment side vertically has groove, and groove communicates with groove, permanent magnet is set in the piston, and fluid tap hole leading portion is a flow export.On the flow monitor body, parallel with ostium, be provided with the tongue tube hole, the thrust reed pipe is housed in the tongue tube hole, regulate making tongue tube corresponding with permanent magnet in the piston by trip bolt.Tongue tube belongs to passive switch, and the contact of one group of interlocking is arranged, and is the main original paper that sends signal, picks out three lead-in wires on reed pipe, and as output line, red-Lan group lead-in wire spreads out of fluid flow signal, and red-Bai group lead-in wire spreads out of the fluid look-at-me.
Flow monitor adopts screw thread or flange coupling device to be installed on the fluid line by inflow entrance and flow export in use, can connect, also can be in parallel.Flow through as fluid, fluid promotes the piston pressuring spring, the permanent magnet in the piston with keep a kind of state in reed pipe, red-Lan group lead-in wire is connected shows signal; When cutout occurring, spring forces piston reset, and piston and tongue tube relative position change, and at this moment red-Bai group lead-in wire is connected and shown the signal that stops.
Adopt said structure, the action of a magnetic field of piston internal magnet shows by signal in tongue tube, can judge that fluid is to flow or interruption, and this flow monitor is highly sensitive, and is simple in structure, and cost is low, installation, easy to adjust, long service life.

Fig. 2 is a left view of the present utility model;
Fig. 3 is the front view of the utility model piston;
Fig. 4 is the left view of the utility model piston;
Fig. 5 is a wiring diagram of the present utility model;
As shown in the figure, the utility model fluid flow monitor, mainly by flow monitor body 1, piston 3 and 7 groups of tongue tubes or, flow monitor body 1 is provided with the fluid ostium 9 and the fluid tap hole 10 of mutual perforation, back-up ring 2 leading portions are inflow entrance 11, back segment is a cylinder barrel, in back-moving spring 5 and piston 3 are housed, permanent magnet is set with piston motion in the piston 3, fluid tap hole 10 leading portions are flow export 12, with the ostium 9 tongue tube hole 4 that be arranged in parallel, in thrust spring 8, tongue tube 7 and set screw 6 are housed, turn the correspondence position that screw 6 is regulated permanent magnets in tongue tubes 7 and the piston 3.Move in cylinder barrel smoothly for equalized pressure makes piston, piston 3 stage casings have groove 13, and the back segment side vertically has groove 14, and groove 13 communicates with groove 14.Pick out three lead-in wires on the tongue tube, as output line, b-c is that cylinder-orchid group lead-in wire spreads out of fluid flow signal, and b-a is that red-white group lead-in wire spreads out of the fluid look-at-me, and outgoing signal shows on controller 15.
