Furthermore, a slide way is arranged in the shell, and the lower pressing head is movably arranged on the slide way.

Furthermore, an elastic element is arranged between the lower pressure head and the driving arm, and the elastic element can be a spring.

Furthermore, the edges of the contact surfaces of the upper pressure head and the lower pressure head and the hose are arc-shaped.

The utility model has the advantages that: the utility model discloses a pressure pipe valve for hose utilizes the actuating arm to promote down the pressure head and remove on the slide in the casing, makes it make progress the pressure head and removes the extrusion and close the hose, utilizes the elasticity and the fluid pressure of hose to make the hose resume the open mode after the actuating arm resets, simple structure, it is with low costs. The edges of the contact surfaces of the upper pressure head and the lower pressure head and the hose are arc-shaped, so that the hose is prevented from being abraded by sharp edges; the driving arm and the lower pressure head adopt the spring to transmit pressure, so that the pressure applied on the hose can be accurately controlled, and the service life of the hose is prolonged. The utility model is suitable for a various hoses are particularly useful for the hose of low discharge. In addition, the present invention is equally applicable to non-solution suspensions, which can be effectively closed even if particles are present in the fluid.

Drawings

FIG. 1 is a schematic view of an open state structure according to an embodiment of the present invention;

fig. 2 is a schematic structural diagram of a closed state according to an embodiment of the present invention.

In the figure: 1. the device comprises a shell, 2, a hose, 3, an upper pressure head, 4, a lower pressure head, 5, a driving arm, 6 and a spring.

Detailed Description

The following detailed description of the present invention is made with reference to fig. 1 and 2, but not limited to the embodiments. For convenience of description, the description of the embodiments is described in terms of the orientation of the positions shown in the drawings, and the orientation description does not limit the specific structure of the pinch valve of the present application.

As shown in fig. 1, a pinch valve for a hose, comprising: a housing 1, a pressure tube assembly and a drive assembly. The shell 1 is in a U shape with an opening facing right, a hose channel in the vertical direction for the hose 2 to pass through is arranged near the left end, and the hose 2 passes through the shell 1. The pressure pipe assembly comprises an upper pressure head 3 and a lower pressure head 4, the upper pressure head 3 and the lower pressure head 4 are respectively located on two sides of the hose 2, and the upper pressure head 3 is integrally formed at the bottom of a U-shaped groove at the left end of the shell and is a protruding rib at the bottom of the U-shaped groove. The casing is inside to be provided with the slide on hose passageway position right side, lower pressure head 4 activity set up on the slide, lower pressure head 4 moves about on the slide, can extrude or loosen hose 2 in the removal process to close or open hose 2. Go up pressure head 3 and lower pressure head 4 and the contact surface border of hose for the arc, avoid the damage of upper and lower pressure head edges and corners to hose 2. The driving assembly comprises a driving arm 5, the driving arm 5 is driven by a motor or other mechanical devices to move in a left-right linear mode and is used for driving the lower pressure head 4 to be close to the upper pressure head 3, and the upper clamping head 3 and the lower clamping head 4 are matched with each other to squeeze the hose 2 to close the hose 2. In order to better control the force applied to the lower ram, an elastic element, which may be a spring 6 or another object with elasticity, such as a rubber pad, is arranged between the lower ram and the driving arm.

The utility model discloses a working process: the tube press valve is first fixed to a bracket (not shown) and the hose 2 is then inserted through the hose passage in the housing to complete the installation. When the hose flow needs to be cut off, namely the pipe pressing valve is closed, a starting motor or other driving mechanism (not shown) drives the driving arm 5 to move leftwards, the driving arm 5 presses the spring 6 to transmit power to the lower chuck 4, and the lower chuck 4 moves leftwards under the guidance of the slideway to be close to the upper chuck 3 to press the hose until the hose 2 is closed and the flow is closed, as shown in fig. 2. When the hose flow needs to be restored, namely the pipe pressing valve is opened, a starting motor or other driving mechanisms (not shown) drive the driving arm 5 to move rightwards, the spring gradually reduces the pressure on the lower pressing head 4, the lower pressing head forces the lower pressing head 4 to move rightwards under the action of the elastic force of the hose and the pressure of liquid in the hose, and accordingly the pipe pressing valve is opened to restore the hose flow, as shown in fig. 1. The driving arm 5 can be controlled to stop moving according to the flow demand during the closing or opening process to achieve the purpose of controlling the flow.

The utility model discloses a pressure pipe valve for hose utilizes the actuating arm to promote down the pressure head and remove on the slide in the casing, makes it make progress the pressure head and removes the extrusion and close the hose, utilizes the elasticity and the fluid pressure of hose to make the hose resume the open mode after the actuating arm resets, simple structure, it is with low costs. The edges of the upper pressure head and the lower pressure head and the contact surface of the hose are arc-shaped, so that the hose is prevented from being abraded by sharp edges and corners. The driving arm and the lower pressure head adopt the spring to transmit pressure, so that the pressure applied on the hose can be accurately controlled, and the service life of the hose is prolonged. The utility model is suitable for a various hoses are particularly useful for the hose of low discharge. In addition, the present invention is equally applicable to non-solution suspensions, which can be effectively closed even if particles are present in the fluid.
