摘要： A valve body and seal assembly comprises a valve body having one or more circumferential seal retention grooves and a dual-durometer elastomeric seal cast-in-place in at least one groove. Each seal comprises first and second sections in contact along a substantially non-planar intra-seal interface. First seal sections typically comprise polyurethane having a higher modulus than the polyurethane typically comprising second seal sections. Residual elastomer shrinkage stress present after curing of a cast-in-place dual-durometer elastomeric seal is redistributed within the seal sections to maintain beneficial preload. Seal configurations described herein are also associated with decreased shear-related elastomer fatigue and extrusion damage associated with repeated valve seat impact. Valve service life is increased by beneficial preload maintained by the synergistic interaction of first and second seal sections.

摘要： A valve body having at least one internal hollow or space comprises two separately formed portions joined by at least one cylindrical web. Internal space may communicate with space outside the valve body via a fluid passage, and internal space may be filled with a substantially incompressible flowable substance to facilitate pressure equalization across the valve body. Forging or casting valve body portions to near-net-shape prior to joining minimizes machining necessary to achieve a final desired shape. Increased valve durability and reduced metal wear arise from the reduced valve body weight and correspondingly reduced impact loading as the valve body moves to seal against a valve seat. A single-durometer or dual-durometer elastomeric seal may be cast and cured in place in a peripheral integral seal retention groove, coupled thereto in part through welding flash protruding into the groove and/or through at least one serration in the groove.

摘要： Suction valve spring retainers mounted using an access bore plug are described for use in plunger pump housings having an offset access bore and incorporating structural features for stress-relief. These pump housing structural features accommodate access bore plugs that secure suction valve spring retainers that are internally located substantially centrally over the suction bore transition area of the plunger pump housing. Access bore plugs are secured in place on the pump housing using one or more threaded retainers. Plunger pumps so constructed are relatively resistant to fatigue failure because of stress-reducing structural features, and they may incorporate a variety of valve styles, including top and lower stem-guided valves and crow-foot-guided valves, in easily-maintained configurations. Suction valve spring retainers mounted in plunger pump housings may also incorporate a suction valve top stem guide. Further, certain structural features of access bore plugs may be dimensioned to aid in improving volumetric efficiency of the pumps in which they are used.

摘要： A valve body and seal assembly comprising a top-stem-guided valve body having at least one cast-in-place elastomeric seal insert in a peripheral seal retention groove and a cast-in-place top guide stem sleeve is made by pouring and curing liquid elastomer in at least one mold comprising the peripheral seal retention groove and the top guide stem. Mold surfaces contacting the poured elastomer are adhesion-inhibiting surfaces which reduce or eliminate background elastomer stress due to shrinkage during curing of the elastomer, and which allow limited relative movement of cast-in-place elastomer with respect to the valve body. Serrations on each of the opposing walls of the seal retention groove are offset to moderate differing stress concentrations in the groove walls.

摘要： A high pressure piston for use within a liner for a reciprocating pump comprises an elastomeric seal and a metallic annular bearing ring having relatively high heat conductivity compared to the liner and seal. During the pump's pressure stroke a portion of the bearing ring elastically expands radially to narrow or close the extrusion gap. Narrowing the gap decreases the tendency for extrusion of piston seal elastomeric material, while closing the gap tends to block elastomer extrusion and establish sliding contact between the bearing ring and the liner. Sliding contact between the bearing ring and liner prevents portions of the piston hub (e.g., a transverse flange) from contacting the liner and damaging it. The heat-conductive bearing ring improves scavenging of frictional heat near the extrusion gap, extending the service life of piston seal elastomer while reducing bearing ring and liner wear. Under reduced pressure on the pump's return stroke, the bearing ring elastically contracts radially, slightly widening the extrusion gap. On the pump's return stroke the slightly wider extrusion gap allows cooling water directed generally toward the proximal flange of the piston hub to better cleanse, as well as cool, the liner wall.
摘要翻译：在用于往复泵的衬套内使用的高压活塞包括与衬套和密封件相比具有相对高的导热性的弹性体密封件和金属环形轴承环。在泵的压力冲程期间，轴承环的一部分径向弹性膨胀以缩小或缩小挤出间隙。缩小间隙减小了活塞密封弹性体材料的挤出倾向，同时关闭间隙倾向于阻止弹性体挤出并且在轴承环和衬套之间建立滑动接触。轴承环和衬套之间的滑动接触防止活塞轮毂（例如横向凸缘）的部分接触衬套并损坏衬套。导热轴承圈改善了挤压间隙附近摩擦热的清除，延长了活塞密封弹性体的使用寿命，同时减少了轴承圈和衬套的磨损。在泵返回行程的减压下，轴承环径向弹性收缩，稍微加宽挤压间隙。在泵的返回行程上，稍微更宽的挤出间隙允许冷却水通常朝向活塞毂的近侧凸缘定向，以更好地清洁并冷却衬套壁。

摘要： A valve body has one or more integral seal retention grooves and one or more interior hollows which may be manufactured using frictional or other types of welding to join two previously formed portions through at least one cylindrical web. Forging or casting valve body portions to near-net-shape prior to joining minimizes machining necessary to achieve a final desired shape. One or more interior hollows and an integral seal retention groove are formed in the welded valve body from features present on the portions joined by welding to form the body. Increased valve durability and reduced metal wear arise from the reduced valve body weight and correspondingly reduced impact loading. An elastomeric seal may be cast and cured in place in a seal retention groove.

摘要： A plunger pump fluid end assembly design in which the suction valve and seat is aligned with the plunger and the fluid end housing is constructed with multiple modules. Modules are held in a rigid assembly by staybolts that connect to the power end of the plunger pump. Said staybolts pass though bores in the central fluid module and the suction seat module and bound by a conventional threaded nut. Packing box modules are bound to the central fluid module by bolts that also pass through separate bores in the same central module. A suction valve spring retainer/plunger spacer within the plunger bore of the assembly shields the intersection of the plunger bore and the discharge bore from destructive erosion damage.
