Abstract

The utility model discloses a convenient check valve, which comprises a valve body and a valve core. The valve body is a tubular member with the two ends thereof to be opened. The valve body comprises an inlet end and an outlet end. The core space of the inner end and the core space of the outlet end are cylinders and the axes of the two core spaces are consistent with each other. The diameter of the cross section of the core space of the inlet end is smaller than the diameter of the cross section of the core space of the outlet end. The valve core is a plate-shaped member. The cross sections of the valve core and the core space of the outlet end are the same with each other in shape and dimension. The thickness of the valve core is uniform. The valve core is movably arranged in the core space of the outlet end through a hinge. One end surface of the valve core is attached to the stepped surface formed at the inlet end and the outlet end. The convenient check valve is simple in structure. When liquid flows in the valve through the inlet end, liquid easily pushes open the valve core so as to flow smoothly. When liquid flows out of the valve through the outlet end, the non-return effect is simply realized due to the blocking of the valve core.

Description

A kind of convenient safety check

Technical field

The utility model relates to a kind of convenient safety check.

Background technique

In various industry water treatment systems, all need use the device that stops medium to be refunded, just safety check.But existing safety check is complex structure often, thereby also more complicated of corresponding production process, and manufacture cost is also just high.

The model utility content

Goal of the invention: in order to overcome the deficiency that exists in the existing technology, the utility model provides a kind of convenient safety check simple in structure, cheap for manufacturing cost.

Technological scheme: for solving the problems of the technologies described above, the technological scheme of the utility model sampling is:

A kind of convenient safety check; Comprise valve body and spool, said valve body is the tubular body of both ends open, comprises entrance point and outlet end; Said entrance point inner chamber is the consistent cylindrical body of axis with the outlet end inner chamber, and entrance point inner chamber cross-sectional diameter is less than outlet end inner chamber cross-sectional diameter; Said spool is the measure-alike and uniform tabular body of thickness of cross section and outlet end shape of cross section, and said spool is movably arranged in the outlet end inner chamber through hinge, and the step surface of an one of which end face and entrance point and outlet end formation is fitted.

Beneficial effect: the convenient safety check that the utility model provides, simple in structure, when liquid when entrance point flows into, can back down the spool of safety check easily, liquid flows smoothly; When liquid when outlet end flows into, because stopping of spool can realize check function simply.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

Be depicted as a kind of convenient safety check like accompanying drawing 1; Comprise valve body 1 and spool 2; Said valve body 1 is the tubular body of both ends open; Comprise entrance point and outlet end, said entrance point inner chamber is the consistent cylindrical body of axis with the outlet end inner chamber, and entrance point inner chamber cross-sectional diameter is less than outlet end inner chamber cross-sectional diameter; Said spool 2 is the measure-alike and uniform tabular body of thickness of cross section and outlet end shape of cross section, and said spool 2 is movably arranged in the outlet end inner chamber through hinge, and the step surface of an one of which end face and entrance point and outlet end formation is fitted.

The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.

Claims
