Wherein: the valve comprises a valve body 10, an inner cavity 11, a notch 12, an inner container 20, a clamping structure 30, a positioning groove 31, a cylinder 32, a sliding hole 33, a limiting groove 34, a clamping plate 35, an end cover 40 and a bolt 41.

Detailed Description

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Embodiment, as shown in fig. 1 to 3, in this embodiment, a novel pinch valve includes a valve body 10, an inner cavity 11 of the valve body 10 is provided with an inner container 20, two ends of the inner container 20 are respectively fixed to two ends of the valve body 10 through end caps 40, and the end caps 40 are connected with the valve body 10 through bolts 41; the upper end and the lower end of the valve body 10 are respectively provided with a clamping structure 30, and the two clamping structures 30 are opposite in position; the clamping structure 30 comprises a positioning groove 31 arranged on the outer wall of the valve body 10, a cylinder 32 is arranged on the positioning groove 31 in a rotating mode on the inner side wall perpendicular to the inner container 20, an arc-surface-shaped sliding hole 33 is arranged on the side wall, opposite to the cylinder 32, of the positioning groove 31, the sliding hole 33 is communicated with the inner cavity 11 of the valve body 10, a clamping plate 35 is arranged in the sliding hole 33 in a sliding mode, the clamping plate 35 is connected with an output shaft of the cylinder 32 in a rotating mode, a limiting groove 31 is arranged on the inner wall, close to the inner wall of the bottom of the positioning groove 31, of the sliding hole 33, and the limiting groove.
