Problems solved by technology

[0003] Among them, in order to ensure the advantages of good sealing during use, the tank bottom valve generally adds a sealing ring in the circumferential direction of the valve core, and the sealing effect of the valve core when closing the valve can be enhanced through the function of the sealing ring. However, In the actual use of the tank bottom valve, because the valve core repeatedly realizes the valve opening and valve closing actions, the sealing ring will be worn in the long run, resulting in leakage afte

Embodiment 1

[0035] A leak-proof detection device is described, such as figure 1 , figure 2 As shown, it includes: a valve body 1; a leakage pipeline 13, which is arranged in the valve body 1, and the leakage pipeline 13 includes: a valve core 9 arranged in the circumferential direction of the tank bottom valve core of the storage tank Leakage feed port 2 connected to retention cavity 15, and leakage discharge port 3 used to detect whether there is leakage in the medium; sealing member 4 is drivenly arranged on the fluid channel of the leakage pipeline , the sealing member 4 has a closed position for blocking the fluid channel, and an open position for communicating the fluid channel; during the actual use of the tank bottom valve, the valve core repeatedly realizes the opening action of the material port 8 and the opening of the material port. 8 Closing action, if things go on like this, it will cause the wear of the sealing ring, resulting in leakage after the valve core and valve are ...

Abstract

The invention discloses an anti-leakage detection device and a tank bottom valve. A valve body, a liquid leakage pipeline and a sealing piece are included; the liquid leakage pipeline is arranged in the valve body and comprises a leaked liquid feeding port communicated with a retention cavity formed in the circumferential direction of a valve element of the tank bottom valve of a storage tank anda leaked liquid discharging port used for detecting whether a medium leaks or not; and the sealing piece is arranged on a fluid channel of the liquid leakage pipeline in a driven mode, and the sealingpiece has a closing position for blocking the fluid channel and an opening position for enabling the fluid channel to be communicated. By providing the anti-leakage detection device, the problem thatthe liquid leakage phenomenon is found after liquid leakage occurs in a valve body of an existing tank bottom valve is solved.

Description

technical field [0001] The invention relates to the technical field of valves, and mainly relates to a leak-proof detection device and a tank bottom valve. Background technique [0002] Tank bottom valves are generally used in the production process systems of biopharmaceutical, fine chemical, and food chemical industries. Tank bottom valves are generally installed at the bottom of their fermentation tanks. The tank bottom valves used in these industries have high requirements for sterility. [0003] Among them, in order to ensure the advantages of good sealing during use, the tank bottom valve generally adds a sealing ring in the circumferential direction of the valve core, and the sealing effect of the valve core when closing the valve can be enhanced through the function of the sealing ring. However, During the actual use of the tank bottom valve, because the valve core repeatedly realizes the valve opening and valve closing actions, the sealing ring will be worn in the l...
