Abstract
A wedge guide has two wedge surfaces. The first angled surface engages a first seat retainer positioned on one side of a gate to lock the first seat retainer in a first pocket. The wedge guide has a second angled surface that engages a second seat retainer on the other side of the gate that locks the second seat retainer in a second pocket. The wedge guide does not affect the movement of the seats that move axially between the gate and the respective seat retainers. Two wedge guides are preferably utilized on opposite non-sealing sides of the gate so that the gate slides between them.
Claims20
A wedge guide for a gate valve, comprising:
- said gate valve comprises a valve body that defines therein a flow bore through said valve body and a gate cavity that intersects said flow bore, a gate is disposed in said gate cavity across said flow bore, said gate being moveable to open and close said flow bore, said valve body defining a first pocket in said valve body on one side of said gate and a second pocket in said valve body on an opposite side of said gate, a first seat assembly surrounding said flow bore, said first seat assembly being positioned between said first pocket and said gate, said first seat assembly comprising a first seat and a first seat retainer, said first seat being adjacent to said gate, said first seat being slidable with respect to said first seat retainer, said first seat being axially movable between said gate and said first seat retainer along an axis through said flow bore, a second seat assembly surrounding said flow bore, said second seat assembly being positioned between said second pocket and said gate, said second seat assembly comprising a second seat and a second seat retainer, said second seat being adjacent to said gate, said second seat being slidable with respect to said second seat retainer, said second seat being axially movable between said gate and said second seat retainer along an axis through said flow bore;
- and
- a wedge guide, said wedge guide comprising a first wedge surface that engages said first seat retainer to urge said first seat retainer into said first pocket to prevent movement of said first seat retainer with respect to said first pocket, said wedge guide comprising a second wedge surface that engages said second seat retainer to urge said second seat retainer into said second pocket to prevent movement of said second seat retainer with respect to said second pocket.
A wedge guide assembly for a gate valve, comprising:
- two wedge guides;
- said gate valve comprising:
- a gate which is moveable to open and close a flow bore through said gate valve, said gate being mounted between said two wedge guides, a valve body defining a first pocket and a second pocket formed in said valve body, each of said first pocket and said second pocket surrounding said flow bore,
- a first seat assembly on a first side of said gate, said first seat assembly comprising a first seat adjacent said first side of said gate, a first seat retainer being mounted in said first pocket, said first seat being slidably mounted with respect to said first seat retainer, said first seat being axially movable between said gate and said first seat retainer along an axis through said flow bore,
- a second seat assembly on a second side of said gate, said second seat assembly comprising a second seat adjacent said second side of said gate, a second seat retainer being mounted in said second pocket, said second seat being slidably mounted with respect to said second seat retainer, said second seat being axially movable between said gate and said second seat retainer along an axis through said flow bore;
- a first wedge surface on each of said two wedge guides that engages said first seat retainer to prevent movement of said first seat retainer in said first pocket with respect to said valve body;
- and
- a second wedge surface on each of said two wedge guides that engages said second seat retainer to prevent movement of said second seat retainer in said second pocket with respect to said valve body.
5 more elements
A wedge guide assembly for a gate valve, comprising:
- said gate valve comprising a gate movable to open and close a flow bore through a valve body, two seat assemblies surrounding said flow bore, said gate being mounted between said two seat assemblies, each of said two seat assemblies comprising a seat retainer and a seat wherein said seat slidingly moves with respect to seat retainer, said seat of each of said two seat assemblies being movable axially between said gate and said seat retainer, said valve body defining two pockets on either side of said gate, said seat retainer of each of said two seat assemblies being inserted into one of said two pockets;
- and
- two wedge guides, each wedge guide comprising two wedge surfaces, said two wedge surfaces of each wedge guide engaging respective surfaces on said seat retainer of said two seat assemblies to prevent said seat retainer of said two seat assemblies from moving with respect to said valve body, said gate being mounted between said two wedge guides.
A wedge guide for a gate valve, comprising:
- said gate valve comprises a valve body that defines therein a flow bore through said valve body and a gate cavity that intersects said flow bore, a gate is disposed in said gate cavity across said flow bore, said gate being moveable to open and close said flow bore, said valve body defining a first pocket in said valve body on one side of said gate and a second pocket in said valve body on an opposite side of said gate, a first seat element that engages said first pocket, a second seat element that engages said second pocket;
- and
- a wedge guide, said wedge guide comprising a first angled surface that engages said first seat element to prevent movement of said first seat element with respect to said first pocket, said wedge guide comprising a second angled surface that engages said second seat element to urge said second seat element into said second pocket to prevent movement of said second seat element with respect to said second pocket.
