Abstract
Abstract A valve having at least one sealing assembly comprising a metal seat ring carried by the valve body and urged toward the valve member by circumferentially disposed coil springs. The springs are disposed within an annular retainer formed of resilient material that is U-shaped in section and which seats within the body recess. The seat ring is sealed with respect to the body and carries resilient means for sealing with respect to the valve working surface of the valve member. Preferably means is provided for injecting a viscous sealant into a region adjacent the sealing means, and means isalso provided for confining the viscous sealant to this region.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
203 words
In a valve construction, a valve body having aligned flow passages, a valve member disposed within the body and movable between open and closed positions to control flow through the passages, a sealing assembly surrounding one of the flow passages and carried by the body, said assembly including a seat ring, the body having a recess serving to accommodate one portion of the seat ring, the recess in section being defined by an end shoulder and a peripheral surface that is cylindrical, sealing means of resilient non-metallic material carried by the other end portion of the seat ring, the valve member having an annular valve surface formed thereon which surrounds said one passage for closed position of the valve member and which is disposed to engage said sealing means, means forming a seal between said first-named seat ring portion and the body, a plurality of circumferentially disposed compression springs disposed within the body recess and engaging said seat ring to urge the same toward the valve member, and spring accommodating means comprising an annular member made of resilient non-metallic material, said member being U-shaped in section and dimensioned to seat against the shoulder of the recess, said springs being accommodated within said member.

In a valve construction, a valve body having aligned flow passages, a valve member disposed within the body and movable between open and closed positions to control flow through the passages, a sealing assembly surrounding one of the flow passages and carried by the body, said assembly including a seat ring, the body having a recess serving to accommodate one portion of the seat ring, the recess in section being defined by an end shoulder and a peripheral surface that is cylindrical, sealing means of resilient non-metallic material carried by the other end portion of the seat ring, the valve member having an annular valve surface formed thereon which surrounds said one passage for closed position of the valve member and which is disposed to engage said sealing means, means forming a seal between said first-named seat ring portion and the body, a plurality of circumferentially disposed compression springs disposed within the body recess and engaging said seat ring to urge the same toward the valve member, and spring accommodating means comprising an annular member made of resilient non-metallic material, said member being U-shaped in section and dimensioned to seat against the shoulder of the recess, said springs being accommodated within said member.
Claim 3
Dependent Claim
42 words
A valve as in claim 1 in which said annular member made of non-metallic resilient material has its outer peripheral wall portion on contact with the peripheral surface of the recess and its inner wall portion in contact with the seat ring.
Claim 4
Dependent Claim
25 words
A valve construction as in claim 2 in which the outer wall portion is shorter than the inner wall portion to facilitate introduction of sealant.
Claim 5
Dependent Claim
22 words
A valve as in claim 2 together with means for introducing a viscous sealant into the recess space occupied by the springs.
Claim 6
Dependent Claim
41 words
A valve construction as in claim 4 in which the seat ring is provided with a duct serving to conduct viscous sealant from the space occupied by the springs to a region near the resilient sealing means engaging the valve member.
Claim 7
Dependent Claim
48 words
A valve construction as in claim 5 together with sealant retaining means carried by the seat ring and serving to enclose the said region into which sealant is introduced, said last means comprising a member of resilient material disposed concentric to and spaced radially from the sealing means.
Claim 8
Dependent Claim
187 words
In a valve construction, a valve body having aligned flow passages, a valve member disposed within the body and movable between open and closed positions to control flow of fluid through the passages, at least one sealing assembly surrounding one of the flow passages and carried by the body, said assembly including a relatively rigid seat ring, the body having a recess serving to accommodate one portion of the seat ring, means forming a fluid-tight seal between one end portion of said seat ring and the body, sealing means of resilient non-metallic material carried by the other end portion of the ring, said valve member having an annular surface formed thereon which surrounds said one passage for closed position of the valve and which is disposed to engage said resilient sealing means, means for introducing a viscous sealant into the region adjacent said sealing means, and sealant retaining means carried by the seat ring and serving to enclose said region, said last means comprising a ribbon-like member of resilient non-metallic material mounted upon the seat ring and disposed concentric to and spaced radially from the sealing means.
