The valve device comprises a hose 1 and a pipe clamping structure 2; the hose 1 is deformably disposed and has a first port and a second port communicating with each other; the pipe clamping structure 2 and the hose 1 are arranged in a split manner, so that the hose 1 can be clamped or loosened through the pipe clamping structure 2; when the hose clamping structure 2 clamps the hose 1, the hose 1 deforms to separate the first port from the second port; when the hose 1 is released by the clamping structure 2, the first port communicates with the second port. The hose clamping structure 2 can clamp or loosen the hose 1; when the hose 1 is clamped by the hose clamping structure 2, the hose 1 deforms under the action of the hose clamping structure 2, so that the first port and the second port are isolated, and fluid in the hose 1 is prevented from flowing between the first port and the second port; when the hose 1 is released by the clamping structure 2, the hose 1 returns to its shape, thereby opening the first port to the second port, allowing fluid inside the hose 1 to flow between the first port and the second port. Compared with other types of valves, the valve device adopting the structural design has the advantages of being not easy to block, not easy to bond and the like, and when the valve device is used in a fluid environment with high viscosity, the service life of the valve device can be effectively prolonged. And because the hose 1 and the pipe clamping structure 2 adopt the split structure, when the hose is blocked or damaged, the hose 1 can be independently replaced without operating the pipe clamping structure 2, and the maintenance operation of the valve device is effectively facilitated. The valve adopting the structural design can be well suitable for controlling the high-viscosity fluid, and the problem that the valve in the prior art is not suitable for being used in the high-viscosity fluid environment is solved.

Specifically, the pipe clamping structure 2 includes: a rotary driver 21, the rotary driver 21 having a driving portion 211 rotatable about a predetermined axis; a slider 22, a central axis of the slider 22 being disposed at a distance from a predetermined axis; the rotary driving member 21 is connected with the slider 22 to drive the slider 22 to rotate about a predetermined axis; the fixing seat 23, the fixing seat 23 is provided with a first guiding structure 231 extending along a first direction; the movable seat 24 is matched with the first guide structure 231 and movably arranged on the fixed seat 23 along the first direction, so that the flexible pipe 1 can be clamped or loosened through the movable seat 24 and the fixed seat 23; a second guide structure 241 extending along the second direction is arranged on the movable seat 24, and the sliding element 22 is matched with the second guide structure 241; wherein the first direction is different from the second direction.

The central axis of the sliding element 22 is spaced from the predetermined axis, that is, the sliding element 22 is disposed eccentrically with respect to the rotary driving element 21, and the driving portion 211 of the rotary driving element 21 rotates to drive the sliding element 22 to move along a circular track. Under the guiding action of the second guiding structure 241, the sliding element 22 can slide in the second direction relative to the movable seat 24, and in cooperation with the guiding action of the first guiding structure 231, the movable seat 24 can finally slide in the first direction relative to the fixed seat 23. Because at least part of the pipe section of the hose 1 is positioned between the fixed seat 23 and the movable seat 24, when the fixed seat 23 and the movable seat 24 are relatively close to each other, the hose 1 can be clamped, so that the first port and the second port are isolated. When fixed seat 23 and movable seat 24 are relatively far away, hose 1 can be loosened, so that the first port is communicated with the second port. Through the pipe clamping structure 2 adopting the structural design, the stable clamping effect can be achieved on the hose 1, and the reliability of the valve device is improved.

In practical implementation, the included angle between the first direction and the second direction may be any angle greater than 0 ° and less than 180 °, and preferably, in order to ensure the driving effect on the movable seat 24, the first direction is perpendicular to the second direction.

When the hose 1 is clamped by the pipe clamping structure 2, the central axis of the sliding member 22, the central axis of the hose 1 and the predetermined axis are in the same plane. That is, assuming that there is a predetermined plane perpendicular to the predetermined axis, the orthographic projection of the predetermined axis, the central axis of the slider 22, and the central axis of the hose 1 in the predetermined plane are collinear. Therefore, the reaction force applied by the hose 1 to the movable seat 24 does not generate a component force in a direction perpendicular to the preset axis, so that the movable seat 24 and the fixed seat 23 can be prevented from being relatively far away, and a reliable clamping effect on the hose 1 is ensured.

The central axis of the hose 1 is a central axis of the hose 1 in a non-deformed state, and the central axis is not changed even if the hose 1 is deformed after being clamped by the pipe clamping structure 2.

The slider 22 includes a rotating shaft and a rolling portion rotatably mounted to the rotating shaft; the rolling part is matched with the inner wall surface of the second strip-shaped groove in a rolling way.

By configuring the sliding member 22 to include a rolling portion, when the sliding member moves along the second linear groove along the second direction, the friction between the sliding member and the movable seat 24 can be reduced by the rolling of the rolling portion, so that the motion of the pipe clamping structure 2 is smoother.

In particular, the rotary drive 21 is positionally adjustably arranged in a first direction relative to the fixed seat 23.

Through adopting above-mentioned setting, the mounted position of adjustable rotary driving piece 21 on fixing base 23 to can drive sliding seat 24 and carry out position control along the first direction, and then play the effect of adjusting the centre gripping effect to hose 1, improve the flexibility that valve device used.
