Embodiment 1

[0029] see figure 1 , figure 2 with image 3 , In one embodiment, a ball valve includes a valve body, a valve stem 4, a valve ball 7, a first sealing pair 12, a second sealing pair 6, and a cleaning member.

[0030] Wherein, the valve body is provided with an accommodating cavity, and an input channel and an output channel communicated with the accommodating cavity. The valve ball 7 is arranged in the accommodating chamber. The valve rod 4 is arranged on the valve ball 7 and protrudes from the valve body to be connected with an external mechanism. The first sealing pair 12 is arranged in the accommodating cavity and corresponds to the input channel, and is used to cooperate with the valve ball 7 to seal the input channel and the accommodating cavity. The second sealing pair 6 is arranged in the accommodating cavity and corresponds to the output channel, and is used to cooperate with the valve ball 7 to seal the output channel and the accommodating cavity.

Embodiment 2

[0047] A furfural production reaction mechanism, including the ball valve in the first embodiment above. By setting the corresponding first sealing pair 12 and the second sealing pair 6 in the housing cavity of the valve body, and cooperating with the valve ball 7, the opening and closing of the inflow channel and the outflow channel are realized. 6 is provided with a cleaning piece to clean the outer surface of the valve ball 7 corresponding to the sealed outflow channel when it is opened, so as to sweep the viscous material or crystal layer condensed on the valve ball 7 and keep the crystallization of the valve ball 7 spherical surface , which solves the problem that the surface of the ball 7 of the existing ball valve cannot be cleaned and is prone to failure.

Abstract

The invention discloses a ball valve and a furfural production reaction mechanism. A first sealing pair and a second sealing pair are correspondingly arranged in a containing cavity of a valve body and are matched with a valve ball to open and close an inflow channel and an outflow channel, and meanwhile, a cleaning piece is arranged on the containing cavity or the second sealing pair, when the ball valve is opened, the outer surface, corresponding to the sealed outflow channel, of the valve ball is cleaned, so that viscous substances or crystal layers condensed on the valve ball are scraped and swept, crystallization of the spherical surface of the valve ball is kept, and the problem that the surface of a valve ball of an existing ball valve cannot be cleaned and is prone to losing efficacy is solved.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a ball valve and a furfural production reaction mechanism. Background technique [0002] Furfural is a colorless transparent oily liquid produced by the hydrolysis of pentosaccharide components in corn cobs, corn stalks, rice husks, cottonseed hulls and agricultural by-product processing waste. A lot of harmful gases will be emitted from the furfural production reaction mechanism, and some of these gases will become viscous substances or even crystals attached to the metal surface when they are cooled. For the ball valves at the top of the mechanism that are used for switching functions, at this stage, either the sealing performance is good at the beginning, but the leakage will be large after a period of use; Long-term accumulation leads to poor sealing performance or easy failure of the ball valve. Contents of the invention [0003] The technical problem to be solved by the ...
