In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: a mechanical valve structure comprising: the valve comprises a valve body and a valve core, wherein a hollow channel is arranged inside the valve body, the valve core is a needle type valve core, a spring is arranged on the outer wall of the valve core, the spring and the valve core are arranged along the hollow channel inside the valve body, a liquid outlet is arranged at the front end of the valve body, a valve hole is formed in the tail end of the valve body, a sealing cover plate is arranged in the valve hole, the spring is arranged between the sealing cover plate and the valve core, a liquid inlet communicated with the hollow channel is formed in one side of the valve body, the front end of the valve core is designed in a conical shape, and the liquid outlet is designed in a conical shape.

Furthermore, the sealing cover plate is in a round table shape.

Furthermore, the tail end of the valve core extends out of the valve body, the tail end of the valve body is provided with internal threads, and the tail end of the valve body is in threaded connection with the valve core cover plate.

Furthermore, the liquid inlet is vertical to the hollow channel.

Further, the valve body outer wall be provided with the annular piece, the annular piece set up in the downside of inlet, the annular piece is mutually perpendicular with the valve body, both can form fixedly with external equipment, also can do benefit to when using, guarantees the perpendicular of valve body and places.

Furthermore, a first sealing ring is arranged between the front end of the valve core and the inner wall of the valve body; and a plurality of second sealing rings are arranged between the middle part of the valve core and the inner wall of the valve body.

Further, the liquid inlet is arranged between the first sealing ring and the second sealing ring.

Furthermore, the outer wall of the valve core is provided with a transition groove, the transition groove is arranged between the second sealing ring and the first sealing ring, the size of the outer wall of the valve core is smaller than that of the hollow channel at the transition groove part, the valve core does not need to be pulled completely, and only a part of the valve core needs to be pulled to finish the flow of liquid.

When the valve core cover plate pulls the valve core to move upwards under the action of external force, the spring is compressed, a gap is formed between the bottom of the valve core and a liquid outlet at the bottom of the valve body, the mechanical valve is opened, and liquid enters from the liquid inlet and flows into the lower side split charging bottle from the liquid outlet through the gap; after the liquid in the bottle reaches the required capacity, cancel external force, the spring resets gradually this moment, promotes the valve core and moves down to case bottom and liquid outlet and laminate completely, and mechanical valve closes this moment, and liquid stops flowing out.

The opening and closing of the mechanical valve can be realized by means of mechanical or electromagnetic driving of the driving part.

Has the advantages that: the liquid leakage prevention valve is simple in structure, sensitive in action and low in cost, and liquid is prevented from leaking through the valve core displacement and the resetting of the spring; when the liquid discharging device is used, the liquid discharging device can be placed to be upright, and liquid discharging is convenient.

Detailed Description

The following describes the embodiments in further detail with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3, a mechanical valve structure includes: valve body 1 and

case

2, 1 inside cavity passageway 3 that sets up of valve body, case 2 be needle type case 2, the outer wall of case 2 set up spring 6, spring 6 sets up along 1 inside cavity passageway 3 of valve body with case 2, the front end of valve body 1 set up liquid outlet 4, the tail end of valve body 1 set up the valve opening, the valve opening setting is sealed apron 5, spring 6 set up and seal between apron 5 and the

case

2, 1 one side of valve body set up the inlet 7 with the cavity passageway intercommunication, 2 front ends of case be the toper design, liquid outlet 4 is the toper design.

The sealing cover plate 5 is in a round table shape.

The tail end of the valve core 2 extends out of the valve body 1, the tail end of the valve body 1 is provided with internal threads, and the tail end of the valve body 1 is in threaded connection with a valve core cover plate 12.
