Abstract
Description
Technical Field
[0001] This invention relates to the field of deep-sea animal terrestrial culture chamber equipment technology, and in particular to a multi-functional reciprocating constant-volume feeding, sewage discharge, and sampling valve specifically designed for deep-sea simulation chambers. Background Technology
[0002] The reciprocating constant-volume feeding, sewage discharge, and sampling valve of the deep-sea simulation chamber is used for feeding deep-sea animals, discharging food residue / excrement / carcasses, and sampling the surrounding environment. The equipment is connected to a pressure chamber simulating the deep sea. Through regular feeding, sewage discharge, and sampling, long-term culture of deep-sea animals can be achieved, providing an experimental basis for research on deep-sea animals.
[0003] Currently, existing technologies for feeding, discharging, and sampling in pressure chambers typically require different interfaces, generally using large-diameter ball valves and small-diameter throttle valves respectively. This approach is inefficient and costly. When the pressure chamber is in a high-pressure or even ultra-high-pressure environment, the sealing performance deteriorates after repeated use of ball valves and throttle valves for feeding, discharging, and sampling. The volume of the medium discharged in a single operation becomes uncontrollable, easily causing excessive pressure fluctuations in the pressure chamber. In summary, existing pressure chamber feeding, discharging, and sampling methods are inefficient, costly, prone to leakage, and have low safety. Summary of the Invention
[0004] In response to the shortcomings of the existing production technologies, the applicant provides a multi-functional reciprocating valve for deep-sea simulation chambers, which is designed for constant-volume feeding, sewage discharge, and sampling. This valve facilitates the feeding of deep-sea animals, the discharge of food residue / excrement / carcasses, and the sampling of the surrounding environment. It offers high overall reliability, efficiency, and safety.
[0005] The technical solution adopted in this invention is as follows:
[0006] A multi-functional reciprocating valve for constant-volume feeding, sewage discharge, and sampling, specifically designed for deep-sea simulation chambers, includes a deep-sea simulation chamber containing deep-sea animals. Horizontal multi-functional valves are installed on the upper and lower parts of the chamber via upper and lower connecting pipes, respectively. The valve also includes an air compressor with a pressure-reducing valve installed at its output. The outlet of the pressure-reducing valve branches into two paths, connecting to an upper solenoid valve and a lower solenoid valve, respectively. The upper solenoid valve is connected to both ends of the upper multi-functional valve via a pipeline, and the lower solenoid valve is connected to the lower multi-functional valve via a pipeline. A flow regulating valve and a gas silencer are connected in series in the circuit between the upper and lower solenoid valves.
[0007] As a further improvement to the above technical solution:
[0008] The structure of a single multi-functional valve is as follows: it includes a valve body, which has a hollow internal structure and steps at both ends inside 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. Guide blocks are fixedly installed on the extension rods and are installed at the steps. End caps are fixedly installed on the two outer end faces of the valve body by screws. An air port is opened in the middle of the end cap. A connecting rod is fixedly installed between the inner surface of the end cap and the valve body. At the same time, the connecting rod passes through the guide block.
[0009] The valve body has a one-piece structure.
[0010] The valve core has an integral structure.
[0011] The valve body and valve core are installed concentrically.
[0012] The end cap 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] The connecting rods are spaced apart and have a hollow sleeve structure with the openings on the guide block, meaning that the outer diameter of the connecting rod is smaller than the diameter of the openings on the guide block.
[0014] A high-pressure port is provided on one side of the valve body, and a first low-pressure port and a second low-pressure port are provided on the other side of the valve body; the valve core is provided with a first channel and a second channel.
[0015] When Channel 1 is connected to the high-voltage interface, Channel 2 is connected to the low-voltage interface; when Channel 2 is connected to the high-voltage interface, Channel 1 is connected to the low-voltage interface.
[0016] The deep-sea simulation chamber has a rectangular cross-section.
[0017] The beneficial effects of this invention are as follows:
[0018] This invention features a compact and rational structure, and is easy to operate. Through the uniquely designed valve core and valve body, and the coordinated operation of other auxiliary mechanisms and components, it can conveniently achieve tasks such as feeding deep-sea animals, discharging food residue / excrement / carcasses, and sampling the surrounding environment. The overall operation is highly reliable, efficient, and safe. Compared to ball valve feeding, sewage discharge, and throttle valve sampling solutions, this invention offers better sealing after feeding, sewage discharge, and sampling under pressure in the deep-sea simulation chamber, resulting in higher safety and lower cost. One reciprocating motion of the valve core allows for two feeding, sewage discharge, and sampling operations, further enhancing efficiency.
[0019] This invention can control the volume of each feeding, sewage discharge and sampling, reducing the risk of pressure fluctuations in the pressure chamber.
[0020] This invention allows for modification of the valve channel diameter based on the size of deep-sea animal food, food residue, excrement, and carcass, making it easier for them to pass through. Attached Figure Description

[0027] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.
[0028] like Figures 1-4 As shown, the multi-functional valve for reciprocating constant-volume feeding, sewage discharge, and sampling in the deep-sea simulation chamber of this embodiment includes a deep-sea simulation chamber 7, in which deep-sea animals 10 are placed.

It also includes an air compressor 1, with a pressure reducing valve 2 installed at the output end of the air compressor 1. The outlet of the pressure reducing valve 2 branches into two paths, which are respectively connected to an upper solenoid valve 6 and a lower solenoid valve 5. The upper solenoid valve 6 is connected to both ends of the upper multi-functional valve 11 through a pipeline, and the lower solenoid valve 5 is connected to the lower multi-functional valve 11 through a pipeline. A flow regulating valve 3 and a gas silencer 4 are connected in series in the circuit between the upper solenoid valve 6 and the lower solenoid valve 5.
[0029] The structure of a single multi-functional valve 11 is as follows: it includes a valve body 1107, which has a hollow internal structure and steps at both ends inside the valve body 1107. A valve core 1111 is installed inside the valve body 1107. Extending rods are symmetrically arranged at both ends of the valve core 1111, and guide blocks 1109 are fixedly installed on the extending rods. The guide blocks 1109 are installed at the steps. End caps 1101 are fixedly installed on the two outer end faces of the valve body 1107 by screws 1102. An air port 1105 is opened in the middle of the end cap 1101. A connecting rod 1104 is fixedly installed between the inner surface of the end cap 1101 and the valve body 1107. At the same time, the connecting rod 1104 passes through the guide block 1109.
[0030] The valve body 1107 has an integral structure.
[0031] The valve core 1111 has an integral structure.
[0032] The valve body 1107 and the valve core 1111 are installed concentrically.
[0033] The end cap 1101 is sealed to the valve body 1107 by a first sealing ring 1103; the outer surface of the guide block 1109 is sealed to the inner surface of the valve body 1107 by a second sealing ring 1106; and the inner surface of the valve body 1107 is sealed to the outer surface of the valve core 1111 by a third sealing ring 1110.
[0034] There are multiple connecting rods 1104 spaced apart. The connecting rods 1104 and the openings on the guide block 1109 form a hollow sleeve structure, that is, the outer diameter of the connecting rods 1104 is smaller than the diameter of the openings on the guide block 1109.
[0035] A high-pressure port 1108 is provided on one side of the valve body 1107, and a first low-pressure port 1112 and a second low-pressure port 1113 are provided on the other side of the valve body 1107; a first channel 1114 and a second channel 1115 are provided on the valve core 1111.
[0036] When channel 1114 is connected to high-voltage interface 1108, channel 1115 is connected to low-voltage interface 1113; when channel 1115 is connected to high-voltage interface 1108, channel 1114 is connected to low-voltage interface 1112.
[0037] The deep-sea simulation cabin 7 has a rectangular cross-section.
[0038] In actual work process:
[0039] The multi-functional valve for reciprocating constant-volume feeding, sewage discharge, and sampling, as described in this embodiment, comprises a 30MPa, 2m... 3The deep-sea simulation chamber 7 houses deep-sea animals 10. Horizontal multi-functional valves 11 are installed on the upper and lower parts of the chamber via DN40 upper connecting pipes 8 and DN40 lower connecting pipes 9, respectively. It also includes an air compressor 1 with an outlet pressure of 0.8 MPa. A pressure reducing valve 2 is installed at the output end of the air compressor 1, which reduces and stabilizes the inlet air pressure at 0.6 MPa. The outlet of the pressure reducing valve 2 branches into two paths, connecting to an upper solenoid valve 6 and a lower solenoid valve 5, respectively. The upper solenoid valve 6 is connected to both ends of the upper multi-functional valve 11 via a pipeline, and the lower solenoid valve 5 is connected to the lower multi-functional valve 11 via a pipeline. The multi-functional valve 11 is connected, and a flow regulating valve 3 and a gas silencer 4 are connected in series in the circuit between the upper solenoid valve 6 and the lower solenoid valve 5. By controlling the upper solenoid valve 6 and the lower solenoid valve 5 to switch their operation once in a time-sharing manner, the valve core of the multi-functional valve 11 will reciprocate once. This allows for two feedings of 30mm diameter bait and two 50mL samplings at the top of the deep-sea simulation chamber 7, and two 50mL sewage discharges and 50mL samplings at the bottom of the deep-sea simulation chamber 7. This reduces the risk of pressure fluctuations in the pressure chamber and improves the efficiency of the multi-functional valve 11, enabling long-term culture of deep-sea animals and providing an experimental basis for research on deep-sea animals.
