Technical Field

The invention relates to the field of pumps, in particular to a novel pump with a rotary one-way valve mechanism.

Background

The existing water pumps can be divided into displacement pumps, vane pumps and the like according to the working principle. The positive displacement pump is a pump for conveying liquid by utilizing the change of the inner volume of a pump cylinder, and mainly comprises: piston pump, plunger pump, diaphragm pump, gear pump, sliding vane pump, screw pump, etc. The positive displacement pumps such as reciprocating pumps have strong self-priming capability, the theoretical flow rate is irrelevant to the working pressure and only depends on the rotating speed, the size of a pump cylinder and the action number. But the flow is not uniform, the rotating speed is not suitable to be too fast, the liquid pollution degree is sensitive, the structure is more complicated, more easily damaged parts are not easy to maintain, the fund consumption is large, and the like. Vane pumps transfer energy by the interaction of rotating vanes with water and are available in the types of centrifugal pumps, axial flow pumps, mixed flow pumps, and the like. At present, the used displacement pump generally has the problems of low efficiency such as pressure, flow attenuation and the like due to the fault of a one-way valve after being used for a period of time, so that the actual use requirement of a rotor pump cannot be met; meanwhile, the one-way valve is frequently opened and closed, so that the one-way valve of the pump is greatly damaged, the one-way valve is easy to break down, and the service life is short.

Disclosure of Invention

The invention provides a novel pump with a rotary one-way valve mechanism, which is used for solving the problem of low efficiency of the novel pump under the variable working condition of the pump due to the fault of the one-way valve.

The prior pump check valve is mainly opened by the pressure of water, and in the actual working state, when the pressure of water is higher and the conveying frequency of inlet and outlet water is higher, a series of problems such as large noise, low strength and the like can be caused by the common metal check valve, so that the pump check valve is very easy to cause fatigue damage. The reason is that: when the speed of pump operation improves, check valve open and close frequency will be far less than rivers business turn over frequency, causes the check valve not to play the non return effect, perhaps the check valve because the frequency is too high and strike too big and make the check valve damage, the problem that from this brings is that novel pump flow, pressure all reduce to some extent, can not satisfy the demand of operating condition.

The solution of the invention is: the force on the novel pump shaft is transmitted to the valve core in the one-way valve cavity by the transmission mechanism, the water inlet and the water outlet are opened at the position corresponding to the valve core, and the opening of the one-way valve is controlled by the rotation of the novel pump shaft.

The utility model provides a novel pump with rotatory check valve mechanism, includes eccentric shaft, triangle rotor, apron, static sealing washer, cylinder body, its characterized in that still lies in: the rotary check valve mechanism and the gear transmission mechanism are also included;

the rotary one-way valve mechanisms are arranged on two sides of the novel pump;

the gear transmission mechanism transmits power to the rotary one-way valve mechanism.

Furthermore, the angle difference of the rotary one-way valves of the two water inlets of the same cylinder body is 90 degrees, and the angle difference of the rotary one-way valves of the water outlets is 90 degrees.

Furthermore, a valve core water inlet and outlet of the rotary one-way valve mechanism and a water inlet and outlet of the novel pump are provided with a water inlet advance angle and a water outlet delay angle.

Further, the valve core is connected with the gear transmission system, and the gear transmission mechanism comprises an output shaft gear, a primary gear and a secondary gear;

further, a static sealing ring, namely an O-shaped ring, is used for sealing between the valve box and the cylinder body;

furthermore, threaded holes are formed in the two sides of the valve box and used for fixing the novel pump;

the novel pump with the rotary one-way valve mechanism has the beneficial effects that: when the rotational speed of novel pump improves or pressure improves, opening of check valve no longer controls opening of check valve by the pressure of water, introduces novel epaxial power of pump to the check valve through drive mechanism on, utilizes opening of novel epaxial power control check valve of pump, has both solved the backward flow problem, has also solved the inefficacy problem that the check valve leads to because pressure and rotational speed are high simultaneously. The service life of the one-way valve is prolonged, and the service life and the efficiency of the rotor pump are improved.
