detailed description

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The structure of the ballast valve for the aerostat according to the embodiment of the present application will be described below with reference to FIGS. 1 to 3 .

As shown in FIG. 2 , in one embodiment of the present application, a ballast valve structure for an aerostat includes a ballast valve spool, and the ballast valve spool includes: a spool frame, a sand discharge pipe, and a coil 3 . The valve core frame includes two metal plates 4 disposed up and down oppositely and two magnetic elements 1 oppositely disposed left and right. The two metal plates 4 are respectively connected with the two magnetic elements 1 to form a valve core frame. The sand discharge pipe runs through the two metal plates 4 arranged up and down, and is located in the valve core frame. The two metal plates 4 , the magnetic element 1 and the sand discharge pipe, which are arranged up and down opposite to each other, constitute a magnetic circuit. The hopper 20 is connected above the sand discharge pipe, and is used for feeding iron sand into the sand discharge pipe.

Specifically, as shown in Figure 1, the working principle of the ballast valve structure is: when there is no iron sand in the sand discharge pipe, a high magnetic potential will be formed near the sand discharge pipe due to the action of the sand discharge pipe. When there is iron sand in the sand discharge pipe, the magnetic resistance of the entire magnetic circuit is reduced and the energy is less. The iron sand cannot escape due to the magnetic attraction, and the ballast valve is closed at this time.

Further, the coil 3 is arranged in the spool frame. When the coil 3 is energized, a magnetic flux with the opposite direction and the same magnitude as the magnetic flux generated by the magnetic element 1 will be formed in the coil 3, which cancels the original magnetic flux. The magnetic flux attracts the iron sand, and the iron sand flows out through the sand discharge pipe under the action of gravity, and the ballast valve is in the open state.

Further, the surfaces of all components of the magnetic circuit are ground, and the surfaces are flat and smooth, so as to reduce the air gap of the magnetic circuit.

Further, the material of the metal plate 4 needs to have high magnetic permeability. In an embodiment of the present application, the metal plate 4 can be an iron plate, a nickel plate, a manganese plate, or other alloy materials with high magnetic permeability.

The sand discharge pipe is made of materials with high magnetic permeability at both ends, and the middle part is a hollow tube composed of materials with low magnetic permeability. Specifically, in an embodiment of the present application, the pipe bodies at both ends of the sand discharge pipe can be pipes made of iron pipes, nickel pipes, manganese pipes and other alloy materials with high magnetic permeability, and the pipe bodies in the middle part can be A tube body made of materials with low magnetic permeability such as aluminum tube or brass tube.

The ballast valve structure for the aerostat provided by the embodiment of the present application adopts the electromagnetic principle as a whole and is a normally closed valve, which can make the ballast valve structure light and compact, and save energy. When the valve is closed, the magnetic element is used to absorb iron sand at the outlet, and the outlet is open. Compared with mechanical valves or other types of valves, it is not easy to block the material, and the reliability is high.

On the lower metal plate 4, and is located outside the spool frame.

Specifically, the iron pipe 5 and the isolation ring 2 together form a sand discharge pipe. When there is no iron sand in the sand discharge pipe, a higher magnetic pressure will be formed near the isolation ring 2 . When the iron sand in the hopper 20 passes through the sand discharge pipe, most of the magnetic lines of force pass through the iron sand, and the energy of the magnetic circuit decreases. If you want to move the iron sand, you must do work on the magnetic circuit, and its gravity is not enough to provide the force to remove the iron sand. The iron sand will be adsorbed near the isolation ring 2 and will not be discharged. At this time, the ballast valve structure is closed. condition.

It is magnetized under a strong magnetic field and can maintain a constant magnetism after magnetization. During magnetization, the magnetic poles of the magnetic element 1 are not on the end faces, but on the opposite upper and lower surfaces, so as to facilitate the adjustment of the magnetic flux in the magnetic circuit. Further, the shape of the magnetic element 1 can be cylindrical or rectangular. Optionally, in an embodiment of the present application, the shape of the magnetic element 1 is a cylindrical shape, and its magnetic poles are located at two opposite positions on the cylindrical circumferential surface and the lower one.
