Description

Technical Field

[0001] The present application relates to the technical field of valve production, and in particular to a visual automatic control stop valve device. Background Art

[0002] The sealing plane of the stop valve disc is perpendicular to the axis of the water flow hole of the valve body. Under the driving action of the valve stem, the valve plate blocks the end face of the water flow hole, thereby achieving a sealing effect, blocking the liquid, and preventing the liquid from flowing into another pipe, making it easier for the operator to perform subsequent related operations.

[0003] In the related technology, the stop valve usually has a valve stem that drives the blocking plate to rotate, and at the same time, the blocking plate enters the inner cavity of the water flow hole. The blocking plate contacts the side wall of the inner cavity of the water flow hole. At this time, the blocking plate divides the inner cavity of the valve body into two isolated parts, thereby blocking the liquid and realizing the flow control and on-off of the liquid.

[0004] Regarding the above-mentioned related technologies, when the pressure of the liquid is high, the blocking plate may be displaced, thereby allowing part of the liquid to flow through the blocking plate, making the flow-blocking effect of the stop valve poor, thereby causing the stop valve to become disabled. Utility Model Content

[0011] By adopting the above technical solution, the fixed part provides support for the installation of the driving cylinder, and at the same time, the driving cylinder drives the blocking plate to slide in the vertical direction, and makes the blocking plate enter the inner cavity of the through hole, thereby dividing the inner cavity of the fixed part into two isolated chambers, thereby completing the function of the stop valve. At the same time, the driving cylinder drives the blocking plate to slide in the vertical direction, the blocking plate and the rack are fixedly connected, the first gear and the rack are meshed, thereby rotating the first gear, and at the same time, the first gear drives the ratchet to rotate through the first transmission member, and the single-phase meshing between the ratchet pawls enables the fixed plate to rotate only in a single direction.

[0018] Optionally, a sealing ring is sandwiched between the sealing plate and the fixing plate, and the sealing ring is fixedly connected to the sealing plate.

[0019] By adopting the above technical solution, the setting of the sealing ring can further fill the gap between the fixed plate and the sealing plate, thereby preventing the liquid from flowing out through the gap between the fixed plate and the sealing plate and affecting the function of the stop valve.

[0020] Optionally, the top wall and the bottom wall of the sealing ring are coaxially provided with guide slopes.

[0021] By adopting the above technical solution and setting the guide slope, when the sealing plate enters the through hole, the thickness of the sealing ring gradually increases, so that the sealing ring can enter the through hole more conveniently, thereby improving the connection stability between the sealing plate and the fixed plate.
