Description

Net cage balance lifting universal valve

Technical Field

The utility model relates to a balanced general type valve that goes up and down of box with a net, it belongs to box with a net valve technical field.

Background

The main structure of the balanced lifting of the net cage in water is the automatic and reasonable opening and closing of the valve, only the problems related to the valve are solved, and the balanced lifting of the net cage is not a domestic and international problem any more. The prior art of lifting the net cage is to utilize various valves to seal a buoyancy pipe, and the net cage is lifted by charging air into the buoyancy pipe and discharging water in the buoyancy pipe to generate buoyancy, and the process is that the net cage is lifted; the gas in the buoyancy pipe is discharged, and simultaneously water enters the buoyancy pipe, so that the buoyancy of the buoyancy pipe reduces the sinking of the net cage, and the net cage descends in the process. Therefore, the valve plays a critical role in the balanced lifting process of the net cage. Because many problems of the valve cannot be solved, the water in the buoyancy pipe of the net cage is not completely discharged and the air is not sealed, the balanced lifting of the net cage cannot be realized, even if the net cage can be freely lifted during trial operation, the basic problems of water discharging, air sealing and the like in long-time use cannot be solved, and the balance problem is solved far. The fundamental problem of the problems is that a reasonable valve cannot be invented, the problem of the valve cannot be solved, and the lifting type net cage cannot be applied to the field on a large scale.

The key of the balanced lifting of the net cage is the automatic and reasonable opening and closing of the valve, and the principle, the structure and the operation of the existing valve are unreasonable, so that the essential problem can not be solved.

The prior valve has the following problems:

1. the function is single, can not be general: some can seal water but not air, or has good air sealing property and unsmooth water flow, so that balanced lifting cannot be realized;

2. unreliable drainage: when water flows rapidly pass through the valve body, vortex can be formed, and the vortex can drive the valve core to move, so that the valve core seals the valve hole when water in the buoyancy pipe is discharged to a small extent, and the valve is invalid;

3. the valve core cannot be sealed for a long time: the valve core of the valve starts to operate normally and can work for a long time, and various attachments are attached to the surface of the valve core, so that the sealing performance of the valve core is gradually lost.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the not enough of existence among the above-mentioned prior art, provide a balanced general type valve that goes up and down of net cage.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

A net cage balance lifting universal valve comprises a valve shell 1, a conical structural body 3 and a valve fixing body 4 which are sequentially arranged from top to bottom, wherein a pressure relief hole 9 is formed in the top of the valve shell 1, a water through air hole 2 is formed in the side wall of the lower part of the valve shell (1), a valve core pressure relief bin 8 is arranged at the upper part in the valve shell 1, and a vortex elimination plate 7 is arranged at the lower part; a valve core 6 is arranged at the lower opening of the conical structure 3; the valve fixing body 4 is internally provided with a valve hole 5.

The water passing holes 2 are uniformly distributed at the lower part of the valve shell 1.

The valve core 6 and the conical structural body 3 are both subjected to nano antifouling treatment.

The valve core 6 is made of non-metal high polymer materials.

The vortex-eliminating plate 7 is of a cross structure and is fixed on the inner wall of the lower part of the valve shell 1.

The working principle of the utility model is as follows:

water inlet and air exhaust: water enters the valve from the valve hole 5, the valve core 6 floats under the action of buoyancy, as shown in figure 2, the water flows out of the valve through the air hole 2, the valve core 6 enters the valve core pressure-relief bin 8 along the track I or II, as shown in figure 3, gas in the valve core pressure-relief bin 8 is discharged out of the valve through the pressure-relief hole 9, and the valve core 6 finally reaches the position shown in figure 4, and the process is that the valve is opened.

Air intake and water drainage: as shown in figure 4, because of the air pressure, the water pressure in the valve changes suddenly, because of the valve core slow-pressing bin 8, the valve core 6 can not move greatly in the valve core slow-pressing bin 8, meanwhile, water flows through the air hole 2 and then flows out of the valve through the valve hole 5, at the moment, the vortex forming is eliminated by the vortex eliminating plate 7, and the valve core 6 can not be driven to sink. When the water level drops to a certain degree, the valve core 6 falls along the I or II track along with the water level as shown in figure 3. When the water in the valve is completely drained, the valve core 6 and the conical structural body 3 are in tight contact to seal the gas, as shown in fig. 2, and the process is valve closing.

Secondly, the utility model discloses use the theory of operation on the box with a net is:

the utility model discloses both can accomplish to lead to water and seal gas, can ventilate again and seal water, make the balanced lift of box with a net. The lifting principle is as follows:

when air is pumped into the buoyancy tube 12 from the outside through the ventilation water-sealing valve 10, water in the buoyancy tube 12 is discharged through the ventilation water-sealing valve 11, meanwhile, air enters the buoyancy tube 12 through the ventilation water-sealing valve 10, the buoyancy of the buoyancy tube 12 is increased, the buoyancy tube can float gradually, and the process is the rising process of the buoyancy tube 12. When the water level is lowered to the position of the water-through and water-sealing air valve 11, the water-through and water-sealing air valve 11 can seal the gas in the buoyancy pipe 12 from leaking out, and the water-through and air-sealing effects are achieved. On the contrary, when water enters the buoyancy tube 12 and the water level reaches the ventilation water sealing valve 10, the ventilation water sealing valve 10 seals the water in the buoyancy tube 12, so as to play a role in ventilation and water sealing. The multiple groups of buoyancy tubes 12 work simultaneously by applying the principle, and the net cage can be lifted in a balanced manner.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
