Abstract
The utility model provides an anti-blocking check valve and relates to a check valve. The anti-blocking check valve comprises a valve body and a spherical valve disc. A liquid outlet and a liquid inlet are respectively arranged on the upper end and the lower end of the valve body. The sidewall of the liquid outlet and the liquid inlet are respectively provided with a liquid outlet connector and a liquid inlet connector. Flow guide limit plates are arranged in the middle of the valve body in the longitudinal direction. Water end faces on the lower portion of the flow guide limit plates are smooth oblique planes. The spherical valve disc is arranged on the liquid inlet below the flow guide limit plates. When the anti-blocking check valve is used, the anti-blocking check valve is installed on a sewage pipeline through the liquid outlet connector and the liquid inlet connector in the longitudinal direction. Since the water end faces on the lower portion of the flow guide limit plates are the smooth oblique planes, hair or other sewage in waster water can not be caught on. Even if some sewage is blocked by the spherical valve disc, the sewage can pass through the spherical valve disc when water flow slows down and the spherical valve disc is in a suspension state. When reverse liquid flow occurs, a sealing ball falls down and blocks the liquid inlet so as to play a non-return role. The anti-blocking check valve is simple in structure, not prone to be blocked, and long in effective working time, and does not affect normal operation of a system.
Description
Technical field
The utility model relates to safety check, says in detail the anti-blocking safety check that is on a kind of fluid machinery, particularly uses on the plumbing drain.
Background technique
As everyone knows, safety check is called again reflux valve, check valve etc., and this class valve mainly is that the medium mobile power that produces in tube road itself realizes opening and closing automatically, and belongs to a kind of automatic valve.Safety check is used for pipe-line system, and its Main Function is to prevent that medium from flowing backwards, preventing pump and drive motor counter-rotating thereof, prevents from that container inner medium from refluxing to release.Safety check also can be used for providing on the pipeline of supply to the auxiliary system that wherein pressure may rise to above main system pressure.Existing safety check comprises valve body, flap and leading truck, between the liquid inlet in valve body and liquid outlet leading truck is set, flap is set in the leading truck, the moving direction of leading truck guiding flap, leading truck top laterally is provided with pin, and pin stops that flap avoids affecting liquid and flow out, and the patent No. of announcing on June 11st, 2008 such as State Intellectual Property Office is 200720043177.5 ball check valve patent, three guide rods are set, and the fluid output inboard is provided with the U-shaped pin.This safety check, the complex structure in the valve body, and the parts of cross setting are arranged in valve body, and when being used for plumbing drain, the strip impurity such as the hair in the sewage can hang over choke valve body on guide rod and the pin, and often the dismounting cleaning is wasted time and energy, the impact normal operation.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, be not easy to block, the effective time is long, avoids affecting the anti-blocking safety check of normal operation.
The technological scheme that the above-mentioned prior art deficiency that solves the utility model adopts is:
A kind of anti-blocking safety check, comprise valve body and globe disk, valve body is respectively equipped with liquid outlet and liquid entering hole in two ends up and down, be respectively equipped with fluid joint and liquid inlet joint on the sidewall of liquid outlet and liquid entering hole, it is characterized in that the middle part vertically is provided with the water conservancy diversion limiting board in the valve body, the end face that meets water of water conservancy diversion limiting board bottom is smooth bevel, and globe disk is arranged on the liquid entering hole of water conservancy diversion limiting board below.
Middle part week at least three water conservancy diversion limiting boards are set evenly upwards in the valve body in the utility model.
Fluid joint and liquid inlet joint are flange in the utility model.
During use, vertically be installed in the utility model on the plumbing drain by fluid joint and liquid inlet joint, during work, sewage with certain pressure backs down globe disk from bottom to top, because the position-limiting action of water conservancy diversion limiting board, globe disk is limited in the middle part in the valve body, and sewage is discharged by liquid outlet through water conservancy diversion limiting board water conservancy diversion.Because the end face that meets water of water conservancy diversion limiting board bottom is smooth bevel, situation can not appear being tangled in any dirts such as the hair in the sewage, even there is dirt to be blocked by globe disk, globe disk is in the moment of vacant state when current slow down, and dirt also can pass through immediately.In that oppositely the liquid outflow is current, thereby falling to blocking liquid entering hole, ball sealer plays the non-return effect.The utility model is simple in structure, be not easy to block, and the effective time is long, and the frequency of dismounting is low, and time saving and energy saving and not impact system works.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Anti-blocking safety check as shown in the figure, comprise valve body 4 and globe disk 5, valve body is respectively equipped with liquid outlet 2 and liquid entering hole 7 in two ends about in the of 4, be respectively equipped with fluid joint 1 and liquid inlet joint 6 on the sidewall of liquid outlet 2 and liquid entering hole 7, as can be seen from the figure liquid joint 1 and liquid inlet joint 6 are flange, the convenient connection.The middle part vertically is provided with water conservancy diversion limiting board 3 in the valve body, and middle part week upwards evenly arranges three water conservancy diversion limiting boards in the valve body of the present utility model, globe disk can be limited to the central position of valve body, strengthens the flowability of liquid.The end face that meets water of water conservancy diversion limiting board 3 bottoms is smooth bevel, and globe disk 5 is arranged on the liquid entering hole of water conservancy diversion limiting board below.During use, by fluid joint and liquid inlet joint the utility model is installed on the plumbing drain, during work, sewage with certain pressure backs down globe disk from bottom to top, because the position-limiting action of water conservancy diversion limiting board, globe disk is limited in middle part in the valve body, and sewage is discharged by liquid outlet behind water conservancy diversion limiting board water conservancy diversion.Because the end face that meets water of water conservancy diversion limiting board bottom is smooth bevel, situation can not appear being tangled in any dirts such as the hair in the sewage, even there is dirt to be blocked by globe disk, globe disk is in the moment of vacant state when current slow down, dirt also can pass through immediately, the end face that meets water of finding water conservancy diversion limiting board bottom through experiment during from the horizontal by 45 ° of-60 ° of angles the safety check whole structure best.In that oppositely the liquid outflow is current, thereby falling to blocking liquid entering hole, ball sealer plays the non-return effect.The utility model is simple in structure, be not easy to block, and the effective time is long, and the frequency of dismounting is low, and time saving and energy saving and not impact system works.
