Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a timed automatic closing valve. Background Art

[0002] In the field of crop planting, crops need to be watered manually at a fixed time. The traditional method is to open and close the valve manually at the set time. This method requires manual walking back and forth in the farmland, which is very physically demanding and easy to cause the valve to be forgotten to be closed due to human negligence, resulting in excessive watering of crops and the death of crops. Therefore, a timed automatic closing valve is designed to solve the above problem. Utility Model Content

[0003] In view of the shortcomings of existing valves, the purpose of the utility model is to provide a timed automatic closing valve, which has the advantages of automatically closing the valve and reducing the number of manual steps.

[0004] To achieve the above-mentioned purpose, a technical solution adopted by the utility model is: a timed automatic closing valve, comprising a valve body, a valve plate, a valve stem, a valve cover, a starting column, a sliding pin, a spring 1, a damping ring and a spring 2, the valve body having an inlet, an outlet and a mounting cavity, the valve stem being arranged in the mounting cavity, the valve plate being arranged between the inlet and the outlet for connecting or disconnecting, a spring 2 for forcing the valve plate to close is also arranged between the valve plate and the valve body, one end of the valve stem is fixedly connected to the valve plate, a sliding pin is arranged at the other end of the valve stem, the valve cover is arranged in the mounting cavity for sealing, the starting column penetrates the mounting cavity and is slidably connected to the valve body, the damping ring is arranged at the contact position between the starting column and the valve body and is fixedly connected to the valve body, the sliding pin slides on the outer edge of the starting column, the spring 1 is arranged on one side of the starting column, and the spring 1 forces the starting column to move to one side;

[0005] Preferably, the outer edge of the start column further has a release groove, and the release groove is arranged corresponding to the contact side of the sliding pin; when the start column is in the initial state, it slides in the release groove, and the valve plate disconnects the inlet and the outlet; after the start column is displaced and the spring is compressed, the sliding pin is not in the release groove, and the valve plate connects the inlet and the outlet;

[0006] Preferably, the damping ring is made of rubber, and the damping ring provides resistance when the start column moves, and the damping ring prolongs the movement time when the spring forces the start column to move to one side;

[0007] Preferably, the contact end surface between the valve plate and the valve body also has a sealing ring;

[0008] The beneficial effects of the utility model are as follows: after the valve is opened, the starting column needs to return to the initial state under the drive of spring 1 before it can be closed, and the damping ring provides movement resistance while the starting column moves, thereby extending the time for the starting column to move to one side, and by controlling the depth of pressing the starting column, the time for the delayed closing of the valve can be synchronously controlled, so that the effect of delayed automatic closing can be achieved after the valve is opened, and there is no need to manually return to close the valve again.

[0014] See also Figure 1 to Figure 2 , the utility model embodiment includes:

[0015] A timed automatic closing valve comprises a valve body 1, a valve plate 2, a valve stem 3, a valve cover 4, a starting column 5, a sliding pin 6, a spring 1 7, a damping ring 8 and a spring 2 9, wherein the valve body 1 has an inlet 11, an outlet 12 and a mounting cavity 13, the valve stem 3 is arranged in the mounting cavity 13, the valve plate 2 is arranged between the inlet 11 and the outlet 12 for connection or disconnection, a spring 2 9 for forcing the valve plate 2 to close is also arranged between the valve plate 2 and the valve body 1, one end of the valve stem 3 is fixedly connected to the valve plate 2, the other end of the valve stem 3 is provided with a sliding pin 6, the valve cover 4 is arranged in the mounting cavity 13 for sealing, the starting column 5 penetrates the mounting cavity 13 and is slidably connected to the valve body 1, the damping ring 8 is arranged at the contact position between the starting column 5 and the valve body 1 and is fixedly connected to the valve body 1, the sliding pin 6 slides on the outer edge of the starting column 5, the spring 1 7 is arranged on one side of the starting column 5, and the spring 1 7 forces the starting column 5 to move to one side;

[0016] The outer edge of the starting column 5 also has a release groove 51, and the release groove 51 is arranged corresponding to the contact side of the sliding pin 6; when the starting column 5 is in the initial state, it slides in the release groove 51, and the valve plate 2 disconnects the inlet 11 and the outlet 12. After the starting column 5 is displaced and the spring 7 is compressed, the sliding pin 6 is not in the release groove 51, and the valve plate 2 connects the inlet 11 and the outlet 12;

[0017] The damping ring 8 is made of rubber. The damping ring 8 provides resistance when the start column 5 moves. The damping ring 8 prolongs the moving time when the spring 1 7 forces the start column 5 to move to one side.

[0018] The contact end surfaces of the valve plate 2 and the valve body 1 also have a sealing ring;

[0019] Through the above settings, in the actual working process, its specific working principle is as follows:

[0020] When watering crops, the start column 5 is manually pressed inwards, so that the start column 5 compresses the spring 7, and while the start column 5 moves, the sliding pin 6 moves out of the release groove 51. During this process, the sliding pin 6 drives the valve stem 3 to move upward, thereby driving the valve plate 2 to open and connect the inlet 11 and the outlet 12, so that the valve is opened to water the crops;

[0021] Delayed automatic closing process: After the start column 5 is displaced and the spring 7 is compressed, the spring 7 forces the start column 5 to move to the initial position. During the movement, due to the contact between the damping ring 8 and the start column 5, the damping ring 8 provides resistance to the movement of the start column 5, thereby causing the time for the spring 7 to force the start column 5 to move to one side to be extended, and the time of delayed closing can be synchronously controlled by controlling the depth of pressing the start column 5. When the start column 5 returns to the initial position driven by the spring 7, the start column 5 will be closed. Figure 1In the initial state shown, the sliding pin 6 is located above the release groove 51. At this time, the spring 9 between the valve plate 2 and the valve body 1 drives the valve plate 2 to close the inlet 11 and the outlet 12, thereby completing the delayed automatic closing.

[0022] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
