Abstract
A tilting disc check valve is provided with a valve assembly comprising a clapper assembly and an annular seal member. The seal member abuts an annular face extending about an inlet passage of the valve and the opposing face of the seal member is abutted by a clapper support member, forming a portion of the clapper assembly, having the form of an interrupted ring. A clapper is pivotally mounted on the clapper support member via a tab extending into the interruption formed therein. A hole formed in the clapper support member and intersecting the interruption thereof and an aperture formed through the tab permit the tab to be connected to the clapper support member via the insertion of a pin into the hole and the aperture.
Claims14
A tilting disc check valve, comprising:
- a body having formed therein a valve chamber, an inlet passage fluidly communicating with the valve chamber and an outlet passage fluidly communicating with the valve chamber, wherein a valve assembly pocket is formed within the valve chamber adjacent the inlet passage for positioning a valve assembly within the valve chamber;
- and
- a valve assembly disposed within the valve assembly pocket, comrpising:
- a seal member disposed in the valve chamber and sealingly engaging portions of the body about the inlet passage of the body, the seal member having a bore formed therethrough in fluid communication with said inlet passage;
- and
- a clapper assembly disposed in the valve chamber between the seal ring and the outlet passage, comprising:
- a clapper support member having the form of an interrupted circular ring, the clapper support member abutting the seal member and having a bore formed therethrough communicating with the bore formed through the seal member, wherein portions of the clapper support member forming the bore formed therethrough are disposed radially outwardly of portions of the seal member forming the bore through the seal member, the interruption extending from the clapper support member bore to an outer peripheral surface thereof and extending therebetween substantially symmetrically about a radius of the circular ring;
- a circular clapper;
- and
- a tab formed on the outer periphery of the clapper and extending therefrom into the interruption in the clapper support member, the tab being pivotally connected to the clapper support member for pivotation to a closed position of the valve wherein the clapper enters the bore formed through the clapper support member to engage the seal member in an occluding relation with the bore formed through the seal member and for pivotation to an open position wherein the clapper disengages the seal member to permit fluid flow through the valve.
A valve assembly for a tilting disc check valve comprising:
- a clapper assembly, comprising:
- a clapper support member having the form of an interrupted circular ring whereby the clapper support member has a bore formed therethrough interruption extending from the clapper support member bore to an outer peripheral surface thereof and extending therebetween substantially symmetrically about a radius of the circular ring;
- a clapper, sized to fit within the bore formed through the clapper support member;
- and
- a tab, formed on the clapper and extending therefrom into the interruption in the clapper support member, the tab being pivotally connected to the clapper support member for pivotation of the clapper into and out of the bore formed through the clapper support member;
- and
- a ring-shaped seal member adjoining one side of the clapper support member to engage the clapper when the clapper is pivoted into the bore formed through the clapper support member.
