The sealing chamber (16) has an outer surface portion which is generally cylindrical in shape when at The pressure-seal assembly (14) is in the closed position. For example, the outer surface portion (16) of the sealing chamber (16) is a jointless tubular portion that slides over the end of the fluid flow portion (10). Sealing chamber (16) longitudinally so that the sealing chamber (16) consists of two or more pieces that seal the bas around the fluid flow gia (10). Fluid flow portion (10). The sealing chamber (16) optionally has ports 0 (not shown in the drawings) to take due, inject or relieve pressure from within the sealing system in the fluid flow ea (10) and the sealing chamber (16) Referring to Figure (2) “when the sealing chamber (16) is a split section”, the chamber seals (18) mate when the pressure-seal assembly (14) is in the closed position. Parts can be placed - Sealing in the chamber (18) along the mating surfaces in 5 sealing chambers (16) so that when the pieces of the sealing chamber (16) cas come together, the chamber (16) forms a sealed body around the fluid flow oa (10). The sealing parts of chamber (18) can be placed along the mating surfaces of the generally flat side parts of the sealing chamber (16) ass. Seals (16). Chamber seals (18) 0 provide sufficient sealing capabilities to seal against the operating pressure of the fluid flow section (10). Chamber seals (18) withstand LE pressure and are resistant to Hydrogen sulfide sulfide x (125).The pressure ram assembly (20) shall be placed at least at one end of the sealing chamber (16).In the embodiments of figures (1-2), the pressure assembly (20) shall be placed at each end of 5 Sealing chamber (16).In an exemplary example of Figure (3), the pressure ram assembly is shown

(25) By sealing the inner surfaces (23) when the inner surfaces (23) meet. And in models

cabal Engaging surface (24) provides sufficient sealing around the fluid flow part

5 (10) so that the sealing parts are not embedded in the surface (25). Each press brake (22) has an inner side (26) and an outer side (28). The inner side (26) contains the sealing chamber (16). The interlocking surface (24) is placed closer to the outer side (28) than to the inner side ( 26) so that the interlocking surface (24) is gia for sealing around the fluid flow gia (10) without the Jalil cane or without being affected by the closing of the sealing chamber (16).

0 In embodiments where the sealing chamber (16) is a divided gia; the inner side (26) of each compression piston (22) is positioned on the sealing chamber (16) so that when each compression piston (22) moves to seal sealing around oa the fluid flow (10); a piece of the sealing chamber (16) moves with that piston (22). The pressure is static with respect to that particular piece

The pressure piston (22) placed on the sealing chamber (16) is stationary compared to the sealing chamber (16). The counter pressure piston (22) which is not placed on the sealing chamber (16) moves relative to the sealing chamber (16). when the compression pistons (22) rotate when the compression sealing assembly (14) moves to the closed position; The inner side (26) of the sealing chamber (16) 5 seals against the side part (16b) of the sealing chamber (16) (Fig. 1). The pressure assembly (20) also includes an operating arm assembly (30). The actuating rod assembly (30) is connected to at least one of the compression pistons (22).The actuating rod assembly (30) moves the compression piston (22) between the retracted position (Fig. 3) and the extended position (Fig. 4). (22) In the retracted position, the push-lock assembly (14) is in the open position 0. When the push-button plunger (22) is in the extended position, the push-lock assembly (14) is in the closed position. The actuating arm assembly has (30) has a shaped end (32) and an elbow end (34). The shaped end (32) of the actuating arm assembly (30) has a machined surface with a curved side that engages with a stand engages bearing (36) of the pressure body 38 (810). It contains

The curved end (34) is on an elbow pin (40) which is Ble for a rotary connecting part. The bent end (34) extends relative to the machined end (32) to move the pressure piston (22) between the retracted and the extended position. The curved screw (40) provides a rotary connection between the curved end (34) and the pressure piston (22). and when the bent end (34) agg is extended by moving the pressure piston (22) towards the extended position; The curved end (34) rotates around the curved screw (40). This rotation causes a counter-rotation of the formed end (32); And the bent side of the formed end (32) wraps along the stand (36). The ram body (38) serves as a support structure for the ram body (22) and operating arm assembly (30). At least one of the ram body (22) pivots around the 0 pivot point (42) of the ram body (38). At least one press brake piston (22) is rotarily connected to the pressure body (38) by means of a curved pin (40) and a secondary baffle (not shown). ) the secondary baffle Ble is from the actuating arm assembly pin (30) that travels in the pressure body path (38); a machined side of the actuation arm assembly (30) that mates with the opposite side of the actuation arm assembly (38) and a knuckle between the arm assembly (5). 30) and the pressure body (38) or other known connection between the actuation assembly and the support structure 011m500. To move the actuation arm assembly (30) between the extended position and the retracted position, a Power sourcedstal (44) may be used. For example The power source (44) is a pressurized fluid source; Jie is a hydraulic system to actuate the press brakes (22) by supplying hydraulic power to the operating arm assembly (30). Power (44) to extend and retract the operating arm assembly (30) by extending the bent end (34) outside the formed end or retracting the bent end (34) into the formed end (32) as desired by the operator. In an example run; during industrial processes such as those associated with the development and distribution of hydrocarbons; At times the operator may experience a leak or anticipate a future leak point 5 in the fluid flow portion of a Jie (10) pipeline, flange, or valve assembly.

That being said, the operator can use a pressure-seal assembly (14) to contain the leak so that the operation is completed at full capacity. With the push-lock assembly (14) in the open position and the operating lever assembly (30) in the retracted position; The operator orients the pressure seal assembly (14) from the side opposite the leak or potential leak point so that the sealing chamber (16) is located at least partially around a fluid flow (10) at the leak location or potential leak point. and when the sealed chamber (16) Ble about ga section; The compression seal assembly (14) may be used at any location along the fluid flow portion (10) that is sized such that the compression seal assembly (14) closes tightly around the fluid flow portion (10). when the leak occurs at a blocked flange; or a valve component or other fluid flow 0 part having an end (Ka esd) that the sealing chamber (16) becomes a tubular ae coupling sized to slide over the end of the fluid flow part (10). In this model One end of the compression seal assembly (14) has a sealing chamber that is sealed at one end and one compression assembly (20) at the opposite end. Moves to the extended position to move the pressure sealing assembly (14) to the closed position. For example “JU” pressurized fluid may be supplied to the power supply hydraulic system (44) to move the pressure sealing assembly (14) to the closed position. og as shown illus When the pressure-sealing assembly (14) moves to the closed position, bent end (34) extends and pressure piston (22) moves to the extended position, bent end (34) turns around the bent pin (40).This rotation 0 causes a counter-rotation of the formed end (22) and the curved side of the formed end (32) wraps along the bearing (36). > Fluid (10) and such that the sealing portions are sized to seal around the fluid flow (10) and contain the operating pressure of the fluid flow portion (10); It has a margin of 5 appropriate security.
