A kind of one-way valve that the utility model enforcement obtains with traffic monitoring effect, after being installed in the quantity-produced pipe-line system, floating body is owing to flow reduces to sink when flow is lower than certain specified threshold value, the magnet of floating body top guide bar upper end and then moves down, make the shift in position of the magnet group on the magnet carrier owing to magnetic effect, thereby make magnet carrier around upper end immovable point deflection, the support contact arm action that this small deflection makes magnet carrier top match with the sensitive switch center contact, normally closed interlock or normally open contact breakdown or closure with sensitive switch, and when playing monitoring, alarming, the effect of output control signal.Therefore, may also be referred to as flow switch.When flow in the pipeline increased, when surpassing certain threshold value, situation was opposite.Try out the occasions such as monitoring of oil mass in monitoring in the cooling water that generator set can not stop, the oil transport pipeline, be subjected to affirming and favorable comment of user, reflect following advantage: 1, compare with letters such as fluid temperature, the pressure parameter that connects the reflection flow in original supervision pipeline, both easy for installation, directly monitored flow parameter again reliably; 2, at the flow threshold of certain appointment, both carry out monitor alarm, realized the output control signal again simultaneously.If cooperate corresponding electromechanical equipment, just can realize automatic interlock monitoring to target flow threshold value in the pipeline.When being lower than certain necessary numerical value when water flow in the cooling water pipeline, the utility model just can in time be reported to the police reliably, and the reserve pump of interlocking starting simultaneously replenishes the cooling water inflow deficiency that causes for a certain reason soon; 3, above-mentioned specified threshold value, can adjust by displacement frame moving up and down on sleeve pipe easily, the utility model has been carved with corresponding threshold value scale in force on sleeve outer wall, its adjustment range can arrive hundreds of cubic metres/hours for a few tenths of cubic metre/hour.Thereby be widely used in the enterprises such as metallurgy, oil, chemical industry, medicine, food, electric power, the monitor alarm and the realization automatic interlock control of fluid flow.
Fig. 1 is the schematic representation that meets the utility model theme.
In conjunction with Fig. 1, implementation detail of the present utility model is described below: adopt Nonferromugnetic material, as castings such as copper, aluminium, and through car, dig the gold machining operation and become valve body (1) and floating body (2).In order to guarantee floating freely of floating body (2), and has certain clearance between the interlayer of valve body (1) inner chamber.Floating body (2) upper-end surface is vertical to be welded with the guide rod (3) that the upper end fixes magnet (5), central authorities on the upper-end surface of valve body (1), and vertical solid welding has match with the external diameter of guide rod (3) sleeve pipe (4) of certain surplus amount of internal diameter.In order to make guide rod (3) reflect floating of floating body (2) in the inner chamber lifting freely of sleeve pipe (4), valve body (1) must make the sleeve pipe (4) on valve body (1) top perpendicular to substantially horizontal when being installed in the tested pipeline, like this, when the variation of the fluid flow in the tested pipeline causes that floating body (2) floats, correspondingly lifting in sleeve pipe (4) of guide rod (3) is reflected in the variable quantity of measured flux on the lifting amount of magnet (5) of guide rod (3) upper end strictly according to the facts in time.
As shown in Figure 1, the top of sleeve pipe (4) is sealed, the inner chamber of valve body (1) is inserted in the bottom from the valve body upper central, outer wall top at sleeve pipe (4) is fixed with displacement frame (9) with adjusting screw (9-1), the center fixed of displacement frame (9) has magnet carrier (7), the upper end of magnet carrier (7) is bound up on the middle fulcrum of displacement frame (9) versatilely, the lower end of magnet carrier (7) is fixed with the magnet group (6) of at least 2 permanent magnet symmetric arrangement, and the top of magnet carrier (7) is manufactured with support contact arm (8) near connecting the fulcrum place.One side of displacement frame (9) is fixed with sensitive switch (10), sensitive switch (10) has at least a group switching centre contact (10-1), normally open contact (10-2), normally closed interlock (10-3) to form, can adopt the microswitch of commercially available same structure, position limit switch etc.The support contact arm (8) on the top of magnet carrier (7) closely cooperates with the center contact (10-1) of sensitive switch (10).When the monitored fluid flow in the pipeline is lower than a certain specified threshold value, be reflected in the corresponding amount of the unsteady sinking of floating body (2), thereby the guide rod (3) on the floating body (2) is measured accordingly together with magnet (5) decline of upper end, because magnetic effect correspondingly offsets to one side the outer magnet group (6) of sleeve pipe (4) and measures accordingly, this side-play amount causes magnet carrier (7) to turn over corresponding amount around the connection fulcrum of upper end, so the skew of the support contact arm (8) on magnet carrier (7) top is amount accordingly, the center contact (10-1) that this value just in time makes sensitive switch (10) disconnects and closed on normally open contact (10-2) from normally closed interlock (10-3), (10-3) inserts in monitor and alarm system when normally closed interlock, normally open contact (10-2) inserts in interlock control system, when then can realize reporting to the police, the output control signal plays the effect of flow switch.
Adjust screw (9-1) when unclamping, displacement frame (9) is at sleeve pipe (4) when outer wall moves up and down, having driven the magnet carrier (7) that is fixed on the displacement frame (9) moves up and down, the magnet group (6) of magnet carrier (7) lower end is and then moved up and down, thereby changed the relative distance between magnet group (6) and the magnet (5), this has just changed deflects into magnet carrier (7) to make support contact arm (8) skew, and the middle center contact (10-1) that causes sensitive switch (10) disconnects and closedly goes up required flow threshold in normally open contact (10) from normally closed interlock (10-3).Hence one can see that, as long as displacement frame (9) is demarcated between the amount of moving up and down of sleeve pipe (4) outer wall and monitored flow of liquid value, just can engrave the threshold value scale (9-2) of corresponding discharge, thereby realize the adjustment of reporting to the police and exporting the pairing flow threshold of control signal at the outer wall of sleeve pipe (4).In order to protect above-mentioned signal transmitting apparatus, be equipped with the electrical equipment lid (11) that covers in top on sleeve pipe (4) top with retaining screw (12).
As everyone knows, if the baffle plate of floating body (2) with unidirectional keying substituted, implementation detail of the present utility model and the above are much at one, in other words, above-mentioned the utility model that is implemented on the float type one-way valve can be used as another kind of embodiment equally, is implemented on the baffle-type one-way valve.
