Abstract
The utility model discloses an independent automatic control constant flow rate valve which comprises an inlet, an outlet and a cavity body with a sealed bottom part, wherein the inlet is arranged in the middle part of the cavity body; the outlet is arranged on the top of the cavity body. The independent automatic control constant flow rate valve is characterized in that the inlet of the cavity body is fixedly provided with a sleeve valve seat; the cross section of the sleeve valve seat is of an 'I' shape; the cavity wall of a middle cavity body of the sleeve valve seat is provided with a plurality of through holes; a cylindrical valve core is fixedly welded on the middle part of a connecting rod; the connecting rod and the valve core penetrate through the middle cavity body of the sleeve valve seat; a floating plate is fixedly arranged on the top of the connecting rod; and a balanced hammer is fixedly arranged on the bottom of the connecting rod. The independent automatic control constant flow rate valve provided by the utility model has the beneficial effects that the flow rate adjustment is independent, an electric source and an air source are not required; as to the flow rate adjustment, even in a state of power off, as long as the regulated fluid pressure is normal, the flow rate can still keep constant. The independent automatic control constant flow rate valve is simple in structure, is convenient to machine, install and overhaul, and the control accuracy is high.
Description
Technical field
The utility model relates to a kind of constant flow valve, and particularly a kind of self-powering type is controlled constant flow valve automatically.
Background technique
Existing flow automatic regulating system because it is added with seal arrangement, easily produces and leaks and surface friction drag, affects the Flow-rate adjustment precision.And complex structure, cost is higher, is difficult to popularize.
Summary of the invention
The purpose of this utility model is to provide a kind of self-powering type automatically to control constant flow valve, and it is simple in structure, easily manufacturing, and do not use seal arrangement, and can not produce and leak and surface friction drag, highly sensitive.
The utility model is to realize like this, described self-powering type is controlled constant flow valve automatically, it comprises the import of being located at cavity middle part, is located at the outlet at cavity top, the cavity of sealed bottom, it is characterized in that: the inlet at cavity is fixed with the sleeve valve seat, the section of sleeve valve seat is " worker " font, is interval with some through holes on the chamber wall of the middle chamber of sleeve valve seat; One connecting rod is arranged, and cylindrical spool of welding is fixed in the position therebetween, and connecting rod and spool thereof pass the middle chamber of sleeve valve seat, are fixed with a kickboard at the top of connecting rod, are fixed with counterweight in the bottom of connecting rod.
In order to improve sensitivity, be interval with four wedge angles triangle through hole up on the chamber wall of the middle chamber of sleeve valve seat described in the utility model.
For the convenient definite value flow of adjusting, establish a connecting tube with valve at the chamber wall of the up and down both sides of kickboard.
The beneficial effects of the utility model are, its Flow-rate adjustment is self-powering type, need not power supply, source of the gas, and with regard to Flow-rate adjustment, even have a power failure, as long as the hydrodynamic pressure that is conditioned is normal, it is constant that flow still can keep.It is simple in structure, be convenient to processing, install, overhaul, and control accuracy is high, and undamped controlling device is not easy to occur the faults such as stuck leakage, also can not produce and vibrate or beat.
Description of drawings
Fig. 1 is the utility model generalized section.
Fig. 2 is sleeve valve seat plan view described in the utility model.
Fig. 3 is the cross sectional plan view of Fig. 2.
Among the figure: 1. cavity, 2. import, 3. outlet, 4. flange in the bottom sealing, 5. sleeve valve seat, 6. middle chamber, 7. triangle through hole, 8. connecting rod, 9. cylindrical spool, 10. kickboard, 11. counterweights, 12. connecting tube with valve.
Embodiment
Self-powering type described in the utility model is controlled constant flow valve automatically, as shown in Figure 1, 2, 3, it comprises the flange in the bottom sealing 4 of the import 2 of being located at cavity 1 middle part, the outlet 3 of being located at cavity 1 top, cavity 1, import 2 places at cavity are fixed with sleeve valve seat 5, the section of sleeve valve seat 5 is " worker " font, is interval with four wedge angles triangle through hole 7 up on the chamber wall of the middle chamber 6 of sleeve valve seat 5; One connecting rod 8 is arranged, and cylindrical spool 9 of welding is fixed in the position therebetween, and connecting rod 8 and cylindrical spool 9 thereof pass the middle chamber 6 of sleeve valve seat 5, are fixed with a kickboard 10 at the top of connecting rod 8, are fixed with counterweight 11 in the bottom of connecting rod 8.For the convenient definite value flow of adjusting, establish a connecting tube 12 with valve at the chamber wall of the up and down both sides of kickboard 10.The utility model or open the through hole of several symmetries in kickboard also can be adjusted the definite value flow.
Kickboard described in the utility model is similar to the orifice plate of differential pressure type orifice meter, but the general orifice plate that detects flow, and the pressure reduction on its both sides is that the variation with flow changes.And the pressure reduction on kickboard both sides is invariable here.Because it places a smooth circular cavity, the external diameter of kickboard is fixed, and the gross weight of kickboard and the spool that is connected with it is certain, so the flow of fluid is also just certain.It can move up and down in pipeline again as the float in the rotameter, but the rotor of rotameter is taper.And the kickboard here is a garden plate, and kickboard links to each other with spool, and spool can move up and down in the middle chamber of sleeve valve seat.When inlet valve is opened, fluid enters the middle chamber of sleeve valve seat, promote the kickboard upstroke, spur simultaneously spool upwards, owing to being interval with four triangle through holes that gradually dwindle from the bottom to top on the chamber wall of the middle chamber of sleeve valve seat, when spool moves upward, the constriction in flow area of the chamber wall of sleeve valve seat, flow descends.When kickboard descended, the circulation area of triangle through hole enlarged on the chamber wall of sleeve valve seat, and flow its kickboard that rises also increases, and the triangle through hole also turns down thereupon on the chamber wall of sleeve valve seat, finally makes flow keep stable.This is just so that the utility model becomes the reliably self-powering type automation equipment of cheapness of the simple performance of a nested structure.
