Double-stop antitheft sampling valve

Abstract

The invention discloses a double cut-off anti-theft sampling valve, which comprises a valve body, two closing parts are rotatably installed in the valve body, and a sealing ring is set on the closing part, and the closing part passes through the sealing ring and the inner wall of the valve body. Sliding and sealing fit, two valve seats are welded on the outer wall of the valve body, and the two valve seats are adapted to the positions of the two closing parts respectively, and two A first rotating hole that is adapted to the position of the two closing parts respectively, and a rotating post is installed in the first rotating hole, one end of the rotating post passes through the sealing ring and is welded on the closing part, and the rotating post's The other end is provided with a thread groove, and the side of the valve seat away from the valve body is provided with a placement groove. The present invention can be easily disassembled and assembled, thus can be easily maintained or replaced, can play an anti-theft function, has a simple structure, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a double cut-off anti-theft sampling valve. Background technique [0002] Existing sampling valves applied to biological fermentation tanks or experimental tanks include valves connected to fermentation tanks or experimental tanks, steam valves connected to high-temperature steam for sterilization, and sampling valves used for sampling. There are many valves, Poor sealing, not easy to disassemble and assemble. In addition, the traditional sampling valve does not have the anti-theft function, which makes the precious bacteria in the fermenter or experimental tank stolen. [0003] Therefore, we propose a double cut-off anti-theft sampling valve to solve the above problems. Contents of the invention [0004] The object of the present invention is to solve the shortcomings in the prior art, and propose a double cut-off anti-theft sampling valve. [0005] In order to achieve the ab...

[0002] Existing sampling valves applied to biological fermentation tanks or experimental tanks include valves connected to fermentation tanks or experimental tanks, steam valves connected to high-temperature steam for sterilization, and sampling valves used for sampling. There are many valves, The sealing is poor and it cannot be easily disassembled. In addition, the traditional sampling valve does not have the anti-theft function, which makes the precious bacteria in the fermenter or experimental tank stolen and lost.
