摘要： A method of manufacturing a valve body having one or more corrosion-resistant internal surfaces. The method involves performing a casting process, which includes pouring a first material into a mold box, to produce a valve body casting made of the first material. During the casting process, a layer of a second material is formed on one or more internal surfaces of the valve body casting, the second material having a higher corrosion resistance than the first material, by: (1) applying, with an additive manufacturing technique, the second material to one or more external surfaces of a core, and (2) inserting the core into the mold box. A portion of the first material binds to the second material on the one or more external surfaces of the core while the first material is poured into the mold box.

摘要： The present invention relates to a method for manufacturing a high performance butterfly valve liner, comprising: a pre-processing step of preparing in advance a PTFE sheet and a cap in a predetermined size and thickness; a first welding step of welding the cap on a hole after forming the hole at a specific position of the prepared PTFE sheet; a second welding step of welding the end of the PTFE sheet after the first welding so as to form the PTFE sheet in a cylindrical shape; and a flaring step of carrying out flaring for spreading the end of the cylindrical PTFE sheet in the shape of a trumpet by means of a flaring tool, thereby finishing a liner. According to the method for manufacturing a high performance butterfly valve liner of the present invention, easy and simple manufacture is possible thereby reducing work time and manufacturing costs. In addition, a large-diameter valve can be readily manufactured without limitations on the size to be formed.

摘要： A gate valve includes a valve body with a flow passage intersected by a gate cavity. The gate valve also includes a gate with a gate body. The gate body has a downstream gate body face, and an upstream gate body face on an opposite side of the gate body. A seat ring is located between each gate body face and the valve body, at the intersection of the flow passage and the gate cavity. Each seat ring has a seat ring face proximate to the gate. At least one removable insert is located between one of the seat ring faces and one of the gate body faces. The insert is removably coupled to one of the faces and formed of a material harder and more wear resistant as compared to the gate body and the seat ring.

摘要： The invention relates to vanes used in butterfly valves utilized in fluid control systems requiring special relationships between passing fluid and vane rotation and furthermore can provide leak proof shut-off when in the closed valve position and due to the extended contact length between the vane and the valve bore assures low opening friction. The invention furthermore features a shape that greatly reduces the customary high dynamic torque created by fluid suction effects on a vane when in the open position.

摘要： A modular lining system for a valve body for use in fluid handling systems including fluid transport tankers, and a method for lining a valve body using the modular lining system. The lining system is slidably inserted into the valve body to protect the valve body from corrosive or other damaging materials. The liners are placed such that they are easily removable for cleaning or replacing when damaged. An actuator comprising a piston is actuated within one of the liners to selectively allow and stop fluid flow.

摘要： Methods and apparatus for selectively blocking or redirecting flow with a valve that compensates for misalignment between a seat and a gate are disclosed. In one aspect, a valve includes a gate having two discs spaced from one another, first and second seats within first and second passageways of the valve, respectively, and at least one lever arm coupled to an actuator for rotating the gate, thereby diverting flow. The lever arm is disposed between the discs and pivotally couples to the gate such that the pivoting movement of the gate enables compensation for the misalignment. A method includes rotating a gate from a first position with a plane of the gate axially aligned with flow to a second position with the disc initially contacting a seat and compensating for the misalignment by pivoting the gate with respect to the lever arm such that the gate squarely contacts the seat.

摘要： In a piston and cylinder assembly the cylinder comprises at least one annular cylinder block received in a complementary bore of a housing. A means for axially retaining the cylinder block in place relative to the housing includes a pair of slidably engaging part spherical surfaces one of which is carried by a radially displaceable member to adjust for misalignment between the cylinder block and an associated retaining component and to thereby alleviate axially offset pressure which might otherwise be applied to the cylinder block.
