Description

Technical Field

[0001] The invention relates to the technical field of deep-sea animal land culture chamber equipment, in particular to a reciprocating constant-volume feeding, sewage discharge and sampling multifunctional valve specially used in deep-sea simulation chambers. Background Art

[0002] The reciprocating constant-volume feeding, sewage discharge and sampling valves in the deep-sea simulation chamber are used for feeding deep-sea animals, discharging food residues / excrement / carcasses, and sampling the environmental media. The equipment is connected to a pressure chamber that simulates the deep sea, and through regular feeding, sewage discharge and sampling and testing, long-term cultivation of deep-sea animals is achieved, providing an experimental basis for research on deep-sea animals.

[0003] At present, the feeding, sewage discharge and sampling of pressure chambers in the prior art usually require different interfaces, which are generally implemented by large-diameter ball valves and small-diameter throttle valves, respectively, with low efficiency and high cost; when the pressure chamber is in a high-pressure or even ultra-high-pressure environment, when feeding, sewage discharge and sampling are performed through ball valves and throttle valves, the sealing performance deteriorates after repeated use, and the single discharge medium volume is uncontrolled, which easily causes the pressure fluctuation of the pressure chamber to exceed the tolerance; in summary, the feeding, sewage discharge and sampling of existing pressure chambers have low efficiency, high cost, easy leakage and low safety. Summary of the invention

[0004] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a reciprocating constant-volume feeding, sewage discharge and sampling multifunctional valve with a reasonable structure for deep-sea simulation chamber, which can conveniently realize the feeding of deep-sea animal food, the discharge of food residues / excrement / carcasses, and the sampling of the environmental medium. The overall working reliability is good, the efficiency is high, and the safety factor is high.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A reciprocating constant-volume feeding, sewage discharge and sampling multifunctional valve specially used in a deep-sea simulation chamber comprises a deep-sea simulation chamber, in which deep-sea animals are placed, and horizontal multifunctional valves are installed at the upper and lower parts of the deep-sea simulation chamber respectively through an upper connecting pipe and a lower connecting pipe; and also comprises an air compressor, at the output end of which a pressure reducing valve is installed, and an outlet of the pressure reducing valve branches into two paths, which are respectively connected to an upper solenoid valve and a lower solenoid valve, the upper solenoid valve is connected to both ends of the upper multifunctional valve through a pipeline, the lower solenoid valve is connected to the lower multifunctional valve through a pipeline, and a flow regulating valve and a gas silencer are connected in series in the circuit between the upper solenoid valve and the lower solenoid valve.

[0007] As a further improvement of the above technical solution:

[0008] The structure of a single multifunctional valve is as follows: it includes a valve body, the interior of the valve body is a hollow structure, and steps are arranged at both ends of the valve body, a valve core is installed inside the valve body, and extension rods extending outward are symmetrically arranged at both ends of the valve core, and guide blocks are fixedly installed on the extension rods, and the guide blocks are installed on the steps; end covers are fixedly installed on the two outer end surfaces of the valve body by screws, an air interface is opened in the middle of the end covers, and a connecting rod is fixedly installed between the inner surface of the end cover and the valve body, and at the same time, the connecting rod passes through the guide block.

[0009] The valve body is of an integrated structure.

[0010] The valve core is of an integrated structure.

[0011] The valve body and the valve core are installed concentrically.

[0012] The end cover and the valve body are sealed by a No. 1 sealing ring; the outer surface of the guide block and the inner surface of the valve body are sealed by a No. 2 sealing ring; the inner surface of the valve body and the outer surface of the valve core are sealed by a No. 3 sealing ring.

[0013] There are a plurality of connecting rods distributed at intervals, and the connecting rods and the openings on the guide blocks are in an empty sleeve structure, that is, the outer diameter of the connecting rod is smaller than the diameter of the openings on the guide blocks.

[0014] A high-pressure interface is arranged on one side of the valve body, and a No. 1 low-pressure interface and a No. 2 low-pressure interface are arranged at intervals on the other side of the valve body; and a No. 1 channel and a No. 2 channel are arranged at intervals on the valve core.

[0015] When channel No. 1 is connected to the high-pressure interface, channel No. 2 is connected to the low-pressure interface No. 2; when channel No. 2 is connected to the high-pressure interface, channel No. 1 is connected to the low-pressure interface No. 1.

[0016] The cross section of the deep sea simulation chamber is a rectangular structure.

[0017] The beneficial effects of the present invention are as follows:

[0018] The present invention has a compact and reasonable structure and is easy to operate. Through the unique design of the valve core and valve body, and the cooperation between other auxiliary mechanisms and components, it can easily realize the feeding of deep-sea animal food, the discharge of food residues / excrement / corpses, and the sampling of the environmental medium. The overall working reliability is good, the working efficiency is high, and the safety factor is high. Compared with the ball valve feeding, sewage discharge and throttle valve sampling scheme, the sealing performance is better after feeding, sewage discharge and sampling under the pressure of the deep-sea simulation cabin, the safety is higher and the cost is lower; the valve core reciprocates once, and two feeding, sewage discharge and sampling can be realized, which is more efficient.

[0019] The present invention can control the volume of each feeding, sewage discharge and sampling, thereby reducing the risk of pressure fluctuation in the pressure chamber.

[0020] The present invention can modify the valve channel caliber according to the size of deep-sea animal food, food residues, excrement and corpses, making them easier to pass through. BRIEF DESCRIPTION OF THE DRAWINGS
