Abstract

The utility model discloses a swing check valve, which comprises a valve body, a valve cap and a bent plate, wherein the bent plate is hung in a recess of the valve body; and the valve body and the valve cap are sealed by a lip shaped sealing ring. The swing check valve is characterized in that: the valve cap wrench is concave inwards. Compared with the prior art, the swing check valve has the advantages that the wrenched part of the valve cap wrench is designed as an inner octagon, so not only space but also materials are saved; the bent plate has an integrated structure, so the parts are prevented from falling apart; besides, the suspension wall of the valve body is thickened, so the valve safer and more reliable.

Description

Swing check valve

Technical field

The utility model relates to a kind of safety check.

Background technique

The valve gap of existing Swing check valve adopts outer-hexagonal or anise to be wrenched more, and outward appearance seems and the comparison heaviness just seems quite inconvenient in narrow place installation.

Summary of the invention

The utility model for the problems referred to above of solving prior art and existing with not enough, a kind of installation, easy to use, light and handy Swing check valve are provided.

The technological scheme that the utility model solves existing issue is: a kind of Swing check valve, comprise valve body, valve gap, bent plate, bent plate hangs in the set groove of valve body, and valve body and valve gap adopt the mouth sealing ring sealing, it is characterized in that described valve gap is wrenched the employing inner concave shape.

Described Swing check valve is characterized in that: described valve gap is interior concave polygon.

Described Swing check valve is characterized in that: the groove of described valve body setting is direct impact briquetting or sand mold moulding.

Described Swing check valve is characterized in that: described bent plate adopts overall structure.

Described Swing check valve is characterized in that: described bent plate directly is placed in the set groove of valve body by pivoted arm.

Described Swing check valve is characterized in that: the suspension wall wall thickness that described valve body is provided with the protection groove is not less than 2mm.

The utility model compared with prior art, its beneficial effect is: the valve gap place of being wrenched is polygonal in being designed to, not only saved the space but also saved material.Bend and pull the employing overall structure, prevent that part from falling apart, the place's thickening of valve body suspension wall makes valve safer, reliable in addition.
