Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:

FIG. 1 is a schematic cross-sectional view of a preferred embodiment of an adjustable contact-free hose automatic shut-off valve of the present invention;

fig. 2 is a schematic diagram of the overall structure of a preferred embodiment of the adjustable contact-free automatic hose shut-off valve of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, an embodiment of the present invention includes:

the utility model provides an adjustable contact-free hose automatic cutout valve, its structure includes: the valve comprises a valve body 9, a connecting channel 13, a piston 5, a movable pressing block 11, a clamping pin 12, a cylinder 6, a cylinder top cover 3, a downward-pressing air inlet nozzle 1 and a reset air inlet nozzle.

The connecting channel is arranged on the valve body, and the connecting channel can penetrate through the valve body and also can be in a groove-shaped structure with an opening on the side surface. The movable pressing block is arranged in the connecting channel, and the clamping pin is arranged at the bottom of the connecting channel.

The cylinder can be fixedly connected with the top of the valve body through an inner hexagonal socket head cap screw 10, the cylinder top cap is arranged at the top of the cylinder, the upper portion of the piston is movably arranged in the cylinder and divides a cavity in the cylinder into a pressing cavity and a resetting cavity, the lower end of the piston penetrates through the movable through groove in the bottom surface of the cylinder and is connected with the movable pressing block so as to drive the movable pressing block to move up and down in the connecting channel, the hose is tightly pressed or loosened through the clamping pin, and the hose is opened and closed.
