Abstract
The utility model discloses a fluid flow switch which is chiefly composed of a honeycomb duct, a swinging wing, a magnet, a dry reed pipe switch and a socket. The socket is arranged on the radial position of the honeycomb duct. The swinging wing movably hinges the lower part of the socket and falls freely on the fluid channel of the honeycomb duct. The magnet is arranged on the freely movable end of the swinging wing. The dry reed pipe switch is arranged on the socket and is in the circular arc line on which the magnet swings following the swinging wing. Because the utility model is chiefly composed of the magnet, the dry reed pipe switch, and the swinging wing which can swing freely, the magnet arranged on the swinging wing can swing following the swinging wing and change the distance between the magnet and the dry reed pipe switch. Therefore, the dry reed pipe switch can be controlled to switch on or switch off. Consequently, the utility model, which can serve as the control switch of the high flow capacity fluid, has the advantages of simple structure, low cost, and reliable movement.
Description
Technical field
The utility model relates to a kind of fluid detecting device, particularly relates to a kind of fluid flow switch.
Background technology
Existing mostly is the low discharge switch, as the used low discharge switch of quick electric water heater, controls on/off by the static pressure of water, so tap can only be installed in the influent side of electric heater, has limited the range of application of electric heater.In large-scale swimming pool, the flow switch that is used for controls such as the discharging of flowing water, the adding of electrolytic salt is comparatively rare.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, with low cost, reliable in action fluid flow switch, and this fluid flow switch can be used to the occasion of big flow and use.
For achieving the above object, technical solution of the present utility model is:
A kind of fluid flow switch, it mainly is made up of mozzle, the pendulum wing, magnet, dry-reed tube switch, base.Described mozzle is the tubular element of two ends conducting; Described base is installed in the radial position of mozzle; The described pendulum wing is movably articulated in the bottom of base and can freely hangs on the fluid passage of mozzle; Described magnet is installed in the freedom of movement end of the pendulum wing; Described dry-reed tube switch is installed on the base and is positioned at magnet on the circular arc line with the swing of the pendulum wing.
It also comprises nut and over cap; Radially be provided with in water conservancy diversion tube wall upper edge one with the transverse tube of mozzle vertical connection, described base is nested with in transverse tube; Between the upper surface of base and transverse tube, be provided with sealing ring; Described nut and transverse tube are spirally connected, and over cap are withheld with base be in the same place.
After adopting such scheme, because the utility model mainly is made up of magnet, dry-reed tube switch and the pendulum wing that can freely swing, be installed in that the magnet of pendulum on the wing can change with the swing of the pendulum wing and dry-reed tube switch between distance, thereby the conducting or the disconnection of control dry-reed tube switch.This pendulum wing is movably articulated in the body, if no fluid by the time, the pendulum wing is in hang all the time because of deadweight, the articulated structure of the pendulum wing is fairly simple, does not in use need maintenance and is not easy to break down, and with low cost.During use, the pendulum wing that magnet is installed will be subjected to the upwards swing of impulse force of current, when current meet or exceed preset value, dry-reed tube switch can be under magneticaction, be in conducting state, when current during less than preset value or when not having current to pass through, the pendulum wing can finally be hang because of deadweight, dry-reed tube switch is in the state that opens circuit when not being subjected to magneticaction.Thus, the utlity model has advantage simple in structure, with low cost, reliable in action, can be used as the control switch of the fluid of big flow.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is an installation diagram of the present utility model;
Fig. 2 is a cutaway view of the present utility model;
Fig. 3 A-3C is a fundamental diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of fluid flow switch, and it mainly is made up of nut 1, the pendulum wing 2, magnet cap 3, magnet 4, connector lug 5, over cap 6, dry-reed tube switch 7, base 8, mozzle 9 and sealing ring 10 (as shown in Figure 2).
Described mozzle 9 is the tubular element of two ends conducting.
Radially be provided with a transverse tube 92 (as shown in Figure 2) on mozzle 9 walls, this transverse tube 92 is with mozzle 9 vertical connections and have external screw thread, and described base 8 is nested with in this transverse tube 92; The described pendulum wing 2 is movably articulated in the bottom of base 8 by rotating shaft 20 and can freely hangs on the fluid passage 91 of mozzle 9; Described magnet 4 is cylindrical magnetic iron 4, and this cylindrical magnetic iron 4 is fastened at the freedom of movement end of the pendulum wing 2 by magnet cap 3; Described dry-reed tube switch 7 is installed on the base 8 and is positioned at magnet 4 on the circular arc line with 2 swings of the pendulum wing.
Described nut 1 is spirally connected with outer wall thread on the transverse tube 92, over cap 6 and base 8 being withheld in nut 1 from transverse tube 92 upper surfaces to inward flange 11; Between the end face of base 8 and transverse tube 92, be provided with sealing ring 10.
Operation principle of the present utility model:
Utilize cylindrical magnetic iron 4 near or away from dry-reed tube switch 7, make its working control circuit closed or disconnect.When tube fluid flow during less than a certain preset value or when not having fluid to pass through, the pendulum wing 2 of the present utility model is because of deadweight is hang, and dry-reed tube switch 7 is in off state away from the magnetic force scope; When having fluid to pass through in the pipe, the pendulum wing 2 is subjected to the upwards swing of impulse force of fluid, thereby the magnet 4 in the drive pendulum wing 2 is near dry-reed tube switch 7, when fluid flow (water) when meeting or exceeding preset value, dry-reed tube switch 7 is in closure state in the magnetic force scope, and the utility model is in channel status.
Fig. 3 A-Fig. 3 C is the operating state of the utility model in different in flow rate.
Fig. 3 A is no flow rate regime, and at this moment, the pendulum wing 2 is basically perpendicular to the longitudinal axis of mozzle 9, and dry-reed tube switch 7 disconnects;
Fig. 3 B is the not enough state of flow velocity, and at this moment, the pendulum wing 2 is an angle with the longitudinal axis of mozzle 9, and dry-reed tube switch 7 is not off-state in the magnetic force scope;
Fig. 3 C is the enough states of flow velocity, and at this moment, the pendulum wing 2 is substantially parallel with the longitudinal axis of mozzle 9, and dry-reed tube switch 7 is closed in the magnetic force scope.
The utility model can be adjusted the preset value of flow by lifting surface area, weight or magnet 4 position on the pendulum wing 2 of regulating the pendulum wing 2.
Inventive point of the present utility model just is: the pendulum wing 2 is movably articulated in the body, when if no fluid passes through, the pendulum wing 2 is in hang all the time because of deadweight, the articulated structure of the pendulum wing 2 is fairly simple, in use do not need to safeguard and be not easy to break down, and with low cost, drive 2 swings of the pendulum wing by fluid, make the magnet 4 that is installed on the pendulum wing 2 near dry-reed tube switch 7, make dry-reed tube switch 7 closed under magneticaction.When underfed, all fluid flow switches that utilizes the deadweight of magnet 4 away from dry-reed tube switch 7 all belong to the scope that the utility model is protected.
