Abstract
Description
Technical Field
[0001] This invention belongs to the field of drainage systems for amphibious vehicles, and specifically relates to a semi-automatic self-closing drainage valve for amphibious vehicles. Background Technology
[0002] Existing drainage valves on amphibious vehicles are typically connected to the vehicle via a pin cover. During vehicle movement, the valve opens due to the bumps and vibrations, allowing external water, dust, or sand to enter the drainage pipes, causing blockages or water ingress into the vehicle, thus creating safety hazards. For these reasons, drainage valves are generally located on the top of the vehicle, which limits their installation options. Summary of the Invention
[0003] In view of the technical problems existing in the prior art drainage valves, the present invention provides a semi-automatic self-sealing drainage valve for amphibious vehicles, which can solve the problem of pipe blockage or water ingress into the vehicle caused by vehicle bumps, further expand the application scope of the drainage valve and improve its applicability in amphibious vehicles.
[0004] The technical solution of this invention is as follows: A semi-automatic self-sealing drainage valve for an amphibious vehicle adopts an integrated design, consisting of a pressure cover, valve body, spring, seat sleeve and nut from top to bottom. A sealing ring is set between the pressure cover and the valve body to ensure the valve's sealing performance.
[0005] Furthermore, the entire drainage valve is connected to the vehicle body by bolts or pins, thereby fixing the valve body to the vehicle body and providing support for the valve body; the bottom of the drainage valve is connected to the drainage pipe.
[0006] Furthermore, drainage valves are installed on the roof or side of the vehicle body.
[0007] Furthermore, the spring acts on the gland through its tension, controlling the opening and closing of the gland.
[0008] Furthermore, the seat cover compresses the spring, and the nut locks the seat cover in place.
[0009] Furthermore, the sealing ring is made of rubber.
[0010] The beneficial effects of this invention are as follows: This invention achieves semi-automatic switching of vehicle drainage through integrated arrangement, and has the advantages of high integration, compact structure and strong adaptability. The integrated structure can be installed on the roof or side of the vehicle body, and the arrangement is flexible. It can effectively solve the problem of drainage valve blockage or water ingress into the vehicle caused by vehicle bumps. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings, but the present invention is not limited thereto.
[0016] like Figure 1 As shown, the drainage valve of the present invention is composed of a pressure cap 1, a sealing ring 2, a valve body 3, a spring 4, a seat 5, and a nut 6 from top to bottom. The sealing ring 2 is made of rubber and is located between the pressure cap 1 and the valve body 3 to ensure the sealing of the valve. The valve body 3 is fixed to the vehicle body by bolts, which provide support for the valve body and realize the connection between the drainage valve and the vehicle body. The pressure cap 1 controls the flow of water by opening and closing. The spring 4 acts on the pressure cap 1 by spring tension to control the opening and closing of the pressure cap 1. The seat 5 presses the spring 4, and the nut 6 locks the seat 5.
[0017] The semi-automatic self-sealing drainage valve is installed on the roof or side of the vehicle body by bolts or pins, and the bottom of the drainage valve is connected to the drainage pipe.
[0018] When amphibious vehicles are traveling on water, the drainage valve plays a crucial role in controlling the flow of water through the drainage system. During normal water travel, the vehicle's movement causes water to splash. Without the drainage valve, the splashed water would enter the drainage system and eventually seep into the vehicle, posing a safety hazard. In special circumstances where water enters the vehicle, it is necessary to drain the water. The drainage valve needs to be opened to ensure the drainage system is clear and to guide the water out of the vehicle.
[0019] The semi-automatic self-closing drainage valve of the present invention has two working states: The first state is closed. When the vehicle is traveling on water or land, the cover 1 is kept closed by the pressure of the spring 4. The sealing ring 2 on the valve body 3 is in contact with the cover 1, and the valve is sealed. Since the spring 4 provides the force to close the cover 1, it can resist the bumps of the land vehicle and the vibration and shaking of the water vehicle, and the valve always remains closed.
[0020] The second state is open. When special circumstances occur and water enters the vehicle, a drainage device is needed to drain the water. When the water reaches the drainage valve through the drainage pipe, it has a certain water pressure. The water exerts pressure on the cover 1, and the spring 4 connected to the cover 1 is compressed, so the cover 1 opens to drain the water.
