Abstract
Abstract A fluid flow valve, particularly of the ball type, with an improved seal and mounting adapter arrangement to permit the valve to be uncoupled in place and swung out or completely removed for repair of maintenance or replacement without disturbing or disconnecting any other portion of the fluid flow system. The valve also includes an improved valve modulating control arrangement which includes frictional locking means coupling the valve control mechanism to the valve member for flow adjustment; but acting to lock the flow adjusting elements and the valve member itself against any significant change in flow control position in response to flow pressures tending to cause an angular shift or rotation of position of the valve element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
In a fluid flow control valve, the combination of a valve body, a flow control valve member mounted for axial rotation in said valve body, an adjustable control assembly rotatably mounted in said valve body and engaging said valve member to effect selective angular rotation thereof, said control assembly comprising a connector part engaging said valve member and a driver part operatively coupled to said connector part, and said control assembly including resilient contractible clutch means frictionally engaging said valve body and having end portions thereof disposed between said connector part and said drive part in the path of angular rotation thereof, said end portions being responsive to rotation of said drive part to cause contraction and release of said clutch means and being responsive to valve member-induced rotation of said connector part to cause expansion and locking of said clutch means on said body.
Claim 2
Dependent Claim
145 words
In a fluid flow control valve, the combination of a valve body, a flow control valve member mounted for axial rotation in said valve body, an adjustable control assembly rotatably mounted in said valve body and engaging said valve member to effect selective angular rotation thereof, said control assembly comprising a connector part engaging said valve member and a driver part operatively coupled to said connector part, and said control assembly including resilient contractible clutch means frictionally engaging said valve body and having end portions thereof disposed between said connector part and said drive part in the path of angular rotation thereof, said end portions being responsive to rotation of said drive part to cause contraction and release of said clutch means and being responsive to valve member-induced rotation of said connector part to cause expansion and locking of said clutch means on said body.
Claim 3
Dependent Claim
21 words
A combination as defined in claim 1, wherein said valve member is a ball having a fluid flow opening extending therethrough.
Claim 4
Dependent Claim
15 words
A combination as defined in claim 1, wherein said clutch means is a pre-stressed spring.
Claim 5
Dependent Claim
16 words
A combination as defined in claim 3, wherein said clutch means is a helical coil spring.
Claim 6
Dependent Claim
15 words
A combination as defined in claim 3, wherein said clutch means is a spiral spring.
Claim 7
Dependent Claim
21 words
A combination as defined in claim 1, wherein there is a lost-motion connection between said connector part and said drive part.
Claim 8
Dependent Claim
21 words
A combination as defined in claim 1, wherein said end portions are responsive to rotation of said parts in either direction.
