20 flow path to prevent fluid from flowing through the valve. Operating the valve in difficult oilfield conditions can result in bore erosion of the valve body as the insert in the insert scrapes against the bore; They often lead to leakage over a short time. Represents the process of repairing the canal valve) such as by welding and turning; Trouble and something uncomfortable in the oil field.

Demonstrations of this technology relate to non-throttle plug valves of the mentioned embodiments of this technology. An expert in the art will understand that in alternative embodiments this technology can be used in other types of valves that have containers configured differently. however; There are many different types of valves suitable for using this technique and it is not necessary for an expert in the art to understand the perspective of the subject matter to be protected; So that pluralism is not guaranteed. In addition to the valves; Other types of high-pressure flow devices are suitable for implementing this technique. for example; The fluid is used in many well servicing applications to contain high pressure fluids; which are often corrosive and/or abrasive; Fluid fracturing in the oil and gas industry. The fluid end includes a Jie-shaped manifold body 0 and a number of components that are installed and sealed on the body; Jie suction and discharge plugs, suction and discharge valves, a stuffing box, a discharge flange discharge flange and suction manifold with those components either alone or with bushing which are illustrated .e.g. valves;operating the fluid end in difficult oilfield conditions can lead to wear of the body leading to leakage in a short period of time.5 represent Body repair is a problem and obstruction in the oil field.Improvements are needed in the internal sealing of high-pressure flow devices to increase life while reducing downtime and operating cost.What is needed is a solution that transfers corrosion (corrosion and abrasion) from the body of the high-pressure fluid flow device to a sealed component with The body There are improvements in these embodiments related to this technique in the illustrative and specific embodiments in the perspective of the elements of protection. The body The container is appended In the form of a sealing surface, the seal is fitted to the body in the cavity and is prepared to extend from the cavity beyond the body hole for sealing against the sealing surface formed by the container. 5 Some models of this technology refer to the valve having a valve body that determines the valve body hole and defines the intersection cavity with the valve body hole. The flow path is configured through the valve body. LED included

The journal anchor is supported by a placa body that allows selective rotation of the valve stem in the flow path. The valve insert is placed between the valve stem and the valve body. The seal on the valve body shall be fitted in the bore and provided to extend from the recess beyond the valve body bore for sealing against a sealing surface formed by the valve insert. Some examples of this technology refer to a fluid flow device having a body that defines the flow path »a container that is mounted on the body in the flow path; and a means of sealing between the body and the container. Some embodiments of this technology refer to a plug valve having a valve body that locates the valve body hole and a seal that is fitted to the valve body adjacent to the valve body hole.

against the trunnion 118 to contain the pressurized fluid within the valve 100 while maintaining external force to rotate the fulcrum 118 by turning the plug 110. In these illustrations the handle 124 is attached to the fulcrum 118 to allow a user to rotate the plug 110 manually. In alternative models not pictured, the trunnion 118 can be rotated by means of a Jide powered 5" wide. The plug 110 includes a bottom journal trunnion 126 which rotates in the body 102 and is secured by the packing 128. The body 102 also forms the holes 116 116b intersecting with the hole 104; Ideally indicated by an inlet and an outlet. For illustrative purposes of this description it is specified that the fluid flows through valve 100 from left to cpa) or into hole 1116 and out of hole 116[b. however; At 0 execution, either slot 116 can provide the input and the other slot 116 can provide the exit. Each insert forms 106 corresponding holes (F130 130b; the inserts 106 are fitted to the valve 100 so that the insert openings 130 can be aligned with the corresponding valve body opening 116. The plug 110 forms a pass-hole 132 allowing the user to optionally align the hole 132 with the orifices 116. Figure 1 depicts the closed position of valve 100 where the plug 110 is rotated so that the by-pass hole 132 is not aligned with the holes 116. Specifically in the closed position of valve 100 depicted in Figure 1 the pressurized fluid in contact with hole 1116 (inlet) impinges against the plug enclosed 110; sealing the rear side of the plug in a metal-to-metal seal against the insert 106b and also the seal between 0 the seal 140 fitted in the insert 106b between it and the valve body bore 104. Thus; in the closed position the Obstructing pressurized fluid from flowing through valve 100. By rotating the plug 110 to the open position (not pictured); the bypass hole 132 is aligned with the holes 116; this allows pressurized fluid to flow through the valve 100 through the LIS component flow path by the valve body (116 openings) insert holes 130; The valve stopper orifice 5 pass 132.

Figure 2 is similar to Figure 1 but depicts an upper entry plug valve 100 dus done according to solutions (gal performed ale) includes plug valve 100 and C1106 inserts 106 > configured as sections for an open vacuum cylinder hollow cylinder instead of inclusions 06m6b in Figure 1 which are sections of an “open hollow cone” ie the conical surfaces 0001681 in Figure 1 are replaced here with cylindrical surfaces. For the purpose of this description it is understood An expert in the art knows that the details of the construction and use of this technology apply equally to each of these valves, as well as other types of valves that are used to control a high-pressure fluid. Only of the pre-implemented solutions. By means of the 140 seal, which is compressed by B n The outer conical surface 108b of the insert 106b and the valve body bore 104. The insert 106b includes the surface 139 defining the bore 144 intersecting with the conical surface 5 outer 108b. The term "intersect with" for the purpose of this description means the medium formed by the cavity 144 of the gap gap in the outer surface 108b of insert 106b. intersecting the configuration of the recess 144 with the surface 108b allowing the fixed end 141 of the seal 140 to be fitted into the recess 144; and specifying the size of the seal 140 such that the distal end 143 of the bore 144 extends beyond the outer conical surface 108b of the seal against the valve body bore 104. This requires that GED 104 specify the sealing surface in which Sealed engagement of insert 106b against the hole 104. Corrosive and/or abrasive fluid may be trapped between seal 140 (fitted into insert 106b) and hole 104 causing ‎ sk hole 104. The seal 140 is indicated in these embodiments for an axial seal due to 5 compressive forces surface 8b on one side and the hole 104 on the other side acting in an axial direction relative to the annular seal 140.

Although models according to Fig. 3 depict only one O-ring 140 surrounding exit 116b; According to previously implemented solutions unrestricted. An expert in the art will understand that in alternative structures more than one seal can be used to provide padding. The 0 seal can be a celastomeric seal, and in other embodiments Gal 5 types of seals such as metal seals, spring seals, and the like can be used. . to include valve seal 110 and trunnion support 118; The retainer nut 120 is notched to the valve body 102. The retainer nut 120 includes the means of sealing the hole of the valve body 104 by means of another seal 146. Similar to Insert 2106’ the Retaining Nut 120 includes the surface 0 147 defining a bore (referred to specifically as a ‘gland nut’ 148) intersecting with the OD surface 121 of the Retaining Nut 120. The nut 146 is supported in the bore 148 and is sized to span behind the outer surface 121 of the seal against a seal formed by bore the valve body 104. The seal 146 in these embodiments is referred to as a radial seal due to the compressive forces from the cap surface 121 on one side and the bore 104 on the other side in a diagonal direction Ring seal ratio 146. Although a radial seal is depicted, in alternative embodiments an axial seal, crush seal, etc. may be used instead of or in addition to the radial seal. By comparison, Fig. 4 is similar to Fig. 3 but depicts ha from The valve 150 is configured according to the embodiments of this technology.Here an insert 151 is similar in some respects but includes a Lede 0 fitted device like the insert 106b (Fig. 3).Specifically the insert 151 has an external conical surface section 153 which does not form a recess for mounting a device itching m. There is no recess in deck 153 where the recess intersects for mounting on the seal. Instead of that; The valve body 152 defines the bore of the valve body 154” and also includes the surface 155 which defines the bore 156 crossed with the bore 4. Again; The term “intersected with” for the purpose of this description and the meaning of the claims 5 includes a device in the bore 156 with a hole in the hole 154. Specifically, the retaining end 157 of the seal 158 is fitted in the socket 156) and because the bore 156 intersects with the hole 154; it is possible to specify

ana seal 158 to extend from the bore 156 beyond the bore 154 so that the distal end 9 of the seal 158 seals against a sealing surface formed by the insert 151. The fluid ASE and/or abrasive may be trapped between the seal 158 (which is mounted on body 152) and the insert 151 which causes the surface of the outer cylinder of the insert 151 to age. Compared to previously implemented solutions, the formation according to Fig. 4 advantageously transfers the wear wear from the bore 4 (of the body 152) to the insert 151. When the wear progresses sufficiently a leak has occurred; Repair or replacement of insert 151 is significantly less complex and less expensive than repairing body 152. Body 152 includes a Lad surface 161 being another bore 160 which intersects the bore of valve body 0 154. The seal 162 is mounted on body 152 in bore 160. once again; due to the intersection with the formation of bore 160 and bore 154; The seal 162 can be sized to extend beyond Gil 154 for sealing against a sealing surface formed by the retainer nut 164. In contrast to the retainer nut 120 in Figure 3; The Retention Nut 164 does not have a lock fitted to it. Instead of that; The seal 162 is fitted to the valve body 152 and sized xual 5 from the bore 160 for sealing against the OD surface 166 of the retention nut 164. In the same manner as above; This technology moves wear wear away from the body 152 to a less complex and cost-effective mating component Dall; In this case it is the retaining nut 164. Figure 5 is a simplified depiction of the valve 150 configured according to AA technology 0 An expert in the art will understand that there are many different images in the configuration which are included in the said models of this technology that are represented in illustrative forms. Ole Figure 6 depicts a valve 170 A configured according to this technology OY each of the seals 172 (174; 176) fitted into corresponding recesses formed in the valve body 184 intersected with the valve body bore 178. The seals are configured 172 ¢ 174 176 to extend away from the corresponding recesses for sealing against the 5 sealing surfaces of inserts 180 and retention nut 182; correspondingly.

Precursor This structure eliminates the wear caused by mounting the seal on a matching component which seals against the valve body bore 178. Figure 7 is an analog depiction of the insert 106 in the previous valve design in Figure 1. In these embodiments the insert 106 marks the slots 170 is intersected with the outer conical surface 108 of the insert 106. The spring 172 is mounted on the insert 106 in each slot 170 and extends from slot 170 to contact with the valve body bore 104 (Fig. 1). as described above; Where the configuration of solutions that were previously implemented by design; By making the valve body bore 104 the sacrificial member of any wear by springs 172. Figure 8 depicts part of valve 150 (from this technique) in Figure 5; but at a different cross-section 0 passes through the recess 170 defined by the surface 190 formed by the valve-body 2. The recess 170 intersects the valve body bore 154 so that the spring 172 can be fitted into the recess 170 at a fixed end and sized to extend from the recess 170 to engage compressively in against an outer conical surface 108 of insert 106 as shown above; This technology transfers wear from the valve body bore 0154 to the less costly and complex 106 insert. 5 Referring to Figure 5 which depicts the plug valve 150 configured according to the models of this technique. An expert in the art will understand this description to mean that this technology transfers the SSH wear from the body hole 2 to the outer conical surface of the insert 151. As age leakage can occur because the free end of the seal 158 SE is away from the surface The outer conical of the insert 151. In some illustrations the repair procedure can list the details of the sole) Leveling the insert 151 0 to provide a new sealing surface for the seal 158 which is fitted to the body 152. Alternatively; The 151 insert can simply be replaced with a new one. In alternative embodiments also a single-use wear member may be located between the outer conical surface of the insert 151 and the body hole 152. For the purpose of this description and protection elements the single-use wear member may be a disposable liner 5 (not pictured) with one surface corresponding to the body bore 152 to act as effectively as the outer conical surface of the insert 151. In some embodiments the inner surface may meet

directly opposite the liner to the outer conical surface of insert 151. Alternatively; The seal can be provided between the inner surface of the liner and the outer conical surface of the insert. This seal can be fitted to the insert and extended for sealing against a sealing surface formed by the liner (eg with the insert 106 in Figure 1); Or the seal may be fitted to the inner surface of the liner and extend for seal against a seal formed by the outer surface of the insert. Returning to another type of flow device suitable for implementing this technique; Figure 9 Sle of a simplified analog cross-sectional depiction of the hydraulic fracturing of the fluid tip 200 formed according to previously implemented solutions. Fluid End 200 is generally a manifold used to deliver high pressure corrosive and/or abrasive fluids; Ideally used in 0 hydraulic fracturing processes in the oil and gas industry. There are sealing areas at the Fluid End 200 that experience the type of wear problems described above in plug valves. Similar to the conventional plug valve 100 pictured in Figure 1 here are a number of components and a seal to manifold body 201. Here again; The erosive member (JST) is by design; it is body 201 rather than the less complex and less expensive matching component 5. eg body 201 identifies the discharge opening 202 in these pictorial hermetically sealed models by inserting a discharge plug 204 and secured by advancing a retaining nut 206 into the body 201. The discharge plug 204 supports a seal 208 which locks against the hole defining the discharge opening 202. Figure 10 is a simplified cross-sectional depiction of the discharge plug 204 having a surface 205 defining the bore 207 where Seal 208 is mounted at an inner diagonal surface 211 of diagonal seal 208. In these illustrations the bore 207 is Ble about square but embodiments cited are not constrained.An expert in the art will understand that the bore configuration 207 is largely determined by any shape Required for installation of the type of seal chosen.Recessed recess 207 intersects with outer surface 5 215 of vacuum plug 204 Le allows seal 208 to be sized such that da not fitted in recess 207 extends beyond outer surface 215 for identification Compressively interesting

as opposed to (il) 209 which defines the discharge orifice 202. In this structure the ASE and/or high pressure abrasive harsh fluid can be injected between the seal 208 and the hole 209 due to the abrasion of the surface of the seal formed by the hole 209. This technology transfers the ISH wear from the body bore 9 to the less complex and expensive vacuum seal 204. . Fluid end bodies have traditionally been made of heat-treated carbon steel so that it is uncommon for the body 1 to crack prior to any advanced body corrosion to a point of creating leakage between the discharge plug 204 and the bore 209. However; Advancement in technology introduces a stainless steel body structure that leads to a longer operating life. As a result; This corrosion cannot be neglected but instead there is a consideration for minimizing corrosion in the fluid end structure. A leading source of bore 209 in conventional dla ends is the seal 208 fitted to and extending from the vacuum plug 204 to seal against a sealing surface formed by the body 201. Fig. 11 is an expanded cross-sectional illustration for the fluid end 230 configured according to this technique; in many places; To transfer the corrosion wear from the body to the least complex and costly component 5 and seal it with the body. The manifold body 232 forms a number of cinterconnected bores, including a discharge bore 234 that forms a discharge orifice 235 similar to the discharge orifice 202 at the conventional fluid end 200 shown in Figure 9. For the purpose of this description, the term 'discharge bore' means a surface defining the discharge orifice 235 is in the discharge plug 236 and the retention nut 238 is fitted. For clarity; although Fig. 11 overlaps with the discharge hole 234 defining 0 upper end of the discharge hole 235 to which the retention nut 238 is attached; the discharge hole 234 also refers to lower portions of the discharge hole 235 where the discharge plug 236 means of sealing to the body 2 and where the valve (not pictured) rests on the body 232. In general, for the purpose of this description the discharge hole forms 4 multidimensional diameters at different longitudinal 05 positions of the discharge opening. Discharge closed 235 by inserting the discharge plug 236 into the discharge hole and secured in position by introducing the retention nut 238. In contrast to the stopper

Conventional 204 in Figure 9 however; The plug 236 does not have a seal fitted to it which seals against the 234 hole. Instead; The seal 236 identifies the sealing surface 7 of a seal (not pictured in Fig. 11) which is fitted into a cavity formed by the surface 239 of the body 232.

Figure 12 is a simplified tomographic zoom-in depicting the structure of a seal. The body 232 includes the surface 239 forming the recess 240 crossed with the Ail hole 234. In these models the seal 2 is installed in the recess 240 to include an outer diagonal surface; Thus it is supported by body 232. As above; The awful grooved shape of the 240 bore is for illustration and is not restricted to the models mentioned. Any shape necessary to mount a coated seal is stated; where 0 is the seal elastic; pulsating (are etc. As shown above, bore 240 intersects CE 234 which allows the seal 242 to be of such a specific size that no part of the seal 242 fits into the bore 240 and extends beyond the bore 240 and beyond the bore 234 for the seal

compactly against the sealing surface 237 (Fig. 11) defined by the vacuum seal 236. The structure of this seal pictured in Fig. 12 transfers wear from the body to the 5 vacuum seal. Significantly improves fluid end operations because operations involving the discharge plug 236 are less complex and less expensive than repairs involving the body 232; Ideally, it includes repair by welding «Nadam 8:-810». Furthermore it; Weld-repair body 232 is pre-cracked in the clad repaired area Longer service life can be achieved by applying an ecrosion-resistant surface treatment to plug 236; Such as high velocity oxygen fuel (HVOF) treatment; tungsten carbide coating; and the like. Therefore, replacing rather than repairing the AST 236 vacuum seal is ideally beneficial, making it advantageous for repairing a leaking valve built according to this technique in the field and thus significantly reducing downtime. Returning to Figure 11; Body 232 includes a surface 241 that defines the cross bore with hole Lay 234 5 for mounting the seal (not pictured) that extends from the bore for sealing against a sealing surface formed by a discharge valve seat (not pictured). in a form

similar; Body 232 includes the surface 243 which is a HAT bore crossed with bore 234 and is primed for mounting another seal (not pictured) that sized to extend from the bore for sealing against a sealing surface formed by a suction valve seat (not pictured) . Multiple references will be made to the same hole 234 for the purpose of ease of description and not to narrow down models cited for this technique. Whether these recesses 241 243 are machined in the same hole or different holes will not modify the perspective of the mentioned models relating to the bore for mounting the seal in the body; ag The installation of the sealing device in the bore and the means of sealing against a sealing surface of a component in the tight interlocking between them. In lie form the suction cup 247 is tightened closed by inserting a 0 suction plug 244 which locates the sealing surface 245 and locks it in place by introducing the retaining nut 246 into the body 232. Again; Body 232 in these illustrations includes a surface 248 which is the bore intersecting the bore 247 and is prepared for mounting the seal (not pictured) extending from the bore and sealing against the sealing surface 245 of the absorbent plug 4. This transfers wear from the body 232 to the absorbent seal 244 compared to the 5 advance models according to this technique were implemented. Body 2 is also a plunger opening 250 with aaa specific to receive the riffing box sleeve sda 254 which is secured in position by introducing a retaining nut 256. The hole 250 is partly formed by a hole 252 having a surface 258 specifying a bore Cross with hole 252) in which the seal is fitted (not pictured) in these illustrations. Although these illustrations use a diagonal seal, the models listed are not restricted. In alternative embodiments other types of construction are mentioned by these Technology using caxial seals, crush seals, etc. Figure 13 is a simplified cross-sectional depiction of the body 232 having a surface 257 5 forming the bore 258. Again, bore 258 intersects the bore of the body 252 which allows sya) to have an outer diagonal surface of a diagonal seal 260 to be fitted into the bore 258. Its shear extends

Another of seal 260 in bore 258 of bore 258 for compression against sealing surface 259 of sleeve 254. Although in these illustrated embodiments a diagonal seal is used; According to the mentioned models is not restricted. An expert in the art will significantly understand that there are other types of seals that may be used in place of or in addition to the diagonal seal pictured; Slug Jie pivot lock; crush seals; and the like.

Figure 14 depicts a number of additional cavities in the 232 body for mounting several devices

Sealing to move the wear away from the body 232 to the compatible component according to the models of this technology. Ole Body 232 includes the surface 266 defining the bore of the cross with the hole of the body defining the discharge opening 235. Consistent with the whole description; This allows the pivot seal (non

0 depicted in Fig. 14 (see Fig. 15) in the recess; The seal is provided to extend from the bore for sealing against the oriented face of the discharge plug 236 (Fig. 11). Figure 15 is an enlarged simplified depiction of the body 232 having a surface 267 defining the bore 273 in which the axial seal 268 is fitted. In these illustrations the seal 268 is conditioned to extend beyond a hole defining the opening of the discharge body 235 for sealing against the discharge plug 236 drilled downward by advance

5 Retention Nut 238 (Fig. 11). In the form of a cage, the structure of the simplified seal depicted in Figure 15 will not be constrained according to the models mentioned and the perspective of the technology to be protected. In alternative embodiments (Sa) the use of a radial seal or crush seal and the like to transfer wear wear from the body 2 to the junction component. A crush seal refers to a seal structure that operates at least to a certain degree axially and diagonally.

Referring to Fig. 14) The body 232 may include other surfaces that create recesses for mounting various other seals. Sie Surface 270 creates a recess for mounting a seal-ready seal against the sealing surface of a suction plug (not pictured); as in Fig. 5 In the same way the body 232 may include the surfaces 272 274 276 which form recesses for mounting the seals prepared for sealing against the sealing surfaces of the stuffing box bushing

5 254 (Fig. 11); dump valve seat (not pictured); the intake valve seat (not pictured); respectively. likewise; The body can include 232 ash 278 surfaces in a cavity configuration

To install a fit-to-tight seal against the suction manifold (not pictured). Common in any case is the sealing device that composes this technology that transfers the sealing wear from body 232 to the less complex and cost-effective connection component attached to body 232. Figure 16 depicts a stuffing box bushing 254 (Figure 11) that is inserted into the plunger hole 235 so that it is fitted The seal 270 in the cavity formed by the surface 258 extending from this cavity and the sealing against the sealing surface 259 specified by the stuffing box sleeve 254. With the stuffing box sleeve 254 inserted into the position of the air pressure which is at a space specified in the clearance gap Between the outer diameter of the stuffing box sleeve 254 and the hole fixing the body of the plunger hole 235 and between the seal 270 and the seal 272 at 0 opposite end of the stuffing box sleeve 254. The air pressure exerts a force that forces the stuffing box sleeve 254 out of the plunger hole 235, which complicates the operation Fabrication and seal integrity at lower end of stuffing-box sleeve 254. (Kay) Configuration of a breather opening 4 between this space and the surrounding space above stuffing-box sleeve 254 to vent the air pressure. Figure 16 also depicts the configuration of the seal 2 Conventional 72 mounted in a 5 bore formed by a stuffing box bushing 254 and extending from this bore for sealing against a hole defining the plunger hole body 235. Said embodiments can incorporate combinations of the conventional construction and configuration of this technology where other things may overlap. Sle without ad It may be advantageous to use a stuffing-box bushing 254 pictured in Figure 16 if it is made or obtained less costly than providing an in-body bore 232 and if the specified seal position is not 0 that is not necessary for the overall design To keep the high-pressure fluid in the flow path. Fig. 16 also depicts the use of the stuffing-box bushing 254 of an open cylindrical shape and its fixation in position by the advance of the retention nut 256 (Fig. 11). This structure will be for illustrative purposes and will not be identified as limiting to technology. There are other configurations that can be used as well. For example, an expert in the art will understand that there is a conventional stuffing box which integrates a sleeve 5 the stuffing box 254 and the retaining nut 256) in a cage shape into a component which includes a bore to support a seal ready for sealing as opposed to a bore that identifies the body with a plunger hole 235. In conventional constructions

Other A stuffing box without this bore is used in combination with an ols seal carrier insert which mates with the stuffing box and presents the bore for seal assembly. In other embodiments mentioned also the sleeve of the stuffing box 254 can be modified to a structure that incorporates a cylindrical-shaped stuffing box junction with a surface seal insert providing the sealing surface 259 (Fig. 11). Returning to Figure 11. The bushing 254 also protects the hole 252 from corrosion by providing a surface of the inner diameter 264 against which the 8m sda stuffing box (not pictured) is tightened. By transferring the wear from body 232 to the less complex and cost-effective sleeve 254. In short, this technology refers to a high-pressure fluid flow apparatus that is composed of a body that determines a flow path; a container fitted to the body; and a means of sealing between the body and the container. This Description and Claims "Container" means the Gale component of the body to provide high-pressure fluid for sealing between the body and the vessel.In some embodiments the valve "container" shown includes moving an optionally positionable component to control fluid flow 5 through the valve; Jie Seal shown and other components including but not limited to wedge pestle clapper ball; clip; etc. On some Jie models the fluid end models shown “isla! Discharge stopper Absorption stopper Discharge valve seat Discharge valve seat absorbed vacuum flange stuffing box bushing; intake manifold; and the like. The term 'seal' means structures shown and equivalent 0 that mount the seal to a body rather than a contact container to transfer wear compared to previously implemented body-to-container solutions. The "seal" does not explicitly include a pre-implemented solution that mounts the seal on the container to extend from and the seal against the body. There are several alternative properties and details of the instrument configuration described here to implement the present technique which are done for the expert in light of the previous discussion; It has been understood that even the versatility and advantages of many models of current technology that were mentioned in the previous description; In addition to the details of the structure and function of dil forms, this description is for explanatory purposes only and changes can be made to it
