Technical Field

[0001] The utility model belongs to the technical field of steam equipment, and particularly relates to a steam chamber process plugging pressure tool and a steam chamber process plugging pressure system. Background Art

[0002] During the manufacturing process of nuclear power steam equipment, process holes will be retained on the side walls of the steam chamber. The process holes are sealed by process plugs. If the seal of the process plug ages, it will affect the sealing effect of the process plug. Due to the high steam pressure, once the seal of the process plug fails, high-pressure steam will be ejected during operation, seriously affecting the safety of personnel and equipment.

[0003] Based on this, it is necessary to perform a pressure test on the steam chamber with a process plug to verify the sealing effect of the process plug and avoid the risk of high-pressure steam spraying due to failure of the process plug seal during equipment operation. However, due to the large volume of the steam chamber and its non-sealing, it is difficult to achieve pressure verification, which hinders the verification of the sealing effect of the process plug.

[0004] Therefore, how to conveniently perform pressure-maintaining work on the process plug is an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0044] The core of the utility model is to provide a steam chamber process plugging pressure tool to facilitate the pressure-maintaining work of the process plugging;

[0045] Another core of the utility model is to provide a steam chamber process plug pressing system having the above-mentioned steam chamber process plug pressing tool.

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] Since the steam chamber is large in size and not airtight, it becomes difficult to perform a pressure test on the process plug on the side wall of the steam chamber. In order to facilitate the pressure test on the process plug, a steam chamber process plug pressure test tool is specially provided.

[0048] Specifically, please refer to Figure 1-Figure 6 The steam chamber process plugging pressing tool disclosed in the embodiment of the utility model includes a transfer two-way block 100 and a process plugging pressing head 200.

[0049] like Figure 1-Figure 3 As shown, the transition two-way block 100 has a first connecting hole 101 and a second connecting hole 102 that are connected to each other. One end of the first connecting hole 101 and the second connecting hole 102 need to penetrate the surface of the transition two-way block 100 to facilitate connection with external components. The first connecting hole 101 and the second connecting hole 102 can penetrate different surfaces of the transition two-way block 100 to facilitate the assembly of external components and facilitate the opening of the first connecting hole 101 and the second connecting hole 102. In this embodiment, the extension directions of the first connecting hole 101 and the second connecting hole 102 are perpendicular to each other. It can be understood by those skilled in the art that the first connecting hole 101 and the second connecting hole 102 can be arranged according to actual needs and are not limited to Figure 1 The two are shown to be perpendicular.

[0050] The first communication hole 101 is used to connect the pressure pump, and the second communication hole 102 is located at the first end of the adapter two-way block 100. The second end of the adapter two-way block 100 is abutted against the cavity wall of the steam chamber 02 through a pre-tightening member. It should be noted that the first end and the second end of the adapter two-way block 100 are opposite ends of the adapter two-way block 100, so that when the pressure is applied, the adapter two-way block 100 can be supported in the steam chamber along the direction of the first end and the second end.

[0051] Please combine Figure 7 It should be noted that Figure 7 The steam chamber process plugging pressing tool 01 shown in the figure is only for illustration, and is convenient for showing its installation position in the steam chamber 02. The specific structure of each component of the steam chamber process plugging pressing tool 01 should be described in detail. Figure 1-Figure 6 The structure shown shall prevail.

[0052] The first end of the process plug pressing head 200 is sealed and connected to the second connecting hole 102, and the second end is used to seal against the inner wall of the steam chamber 02. That is, during the pressing, the first end of the transfer two-way block 100 abuts against the inner wall of the steam chamber through the process plug pressing head 200, and the second end of the transfer two-way block 100 abuts against the inner wall of the steam chamber 02 through the pre-tightening member, thereby completing the installation of the steam chamber process plug pressing tool 01 in the sealed chamber 02. Specifically, the second end of the process plug pressing head 200 can be sealed against the inner wall of the steam chamber 02 through a sealing gasket.

[0053] The first end of the process plugging head 200 is located at a position corresponding to the process plug 03, and the process plug 03 is sealed and connected to the process hole of the steam chamber 02, so the first end of the process plugging head 200 is correspondingly abutted at the position where the process hole is located. The process plugging head 200 has a third connecting hole 204 that passes through both ends, and the third connecting hole 204 is connected to the second connecting hole 102. Since the first end of the process plugging head 200 is abutted at the position where the process hole is located, the third connecting hole 204 is connected to the process hole.

[0054] The utility model provides a steam chamber process plug pressing tool 01. When the process plug 03 is subjected to a pressure test, the second end of the process plug pressing head 200 is used to seal against the inner wall of the steam chamber 02 and is maintained at a position corresponding to the process plug, so that the third connecting hole 204 remains connected with the process hole at the process plug.

[0055] The second end of the adapter two-way block 100 needs to be abutted against the wall of the steam chamber 02 through a pre-tightening member. Under the action of the pre-tightening member, the two ends of the steam chamber process plug pressing tool 01 are ensured to be pressed against the wall of the steam chamber 02, ensuring the sealed connection between the third connecting hole 204 and the process hole. Use a pressure pump to connect the first connecting hole 101 of the adapter two-way block 100 to perform pressure and pressure holding operations. Since the third connecting hole 204, the second connecting hole and the first connecting hole 101 are in a connected state, the pressure of the pressure pump can act on the process hole to verify the sealing effect of the process plug 03.

[0056] The utility model can directly apply the pressure of the pressure pump to the process hole, and is easy to install in the steam chamber 02. Compared with directly applying the pressure of the pressure pump to the steam chamber 02, it is easier to achieve sealing, and is not affected by the large volume and non-airtightness of the steam chamber 02, and can conveniently perform pressure-maintaining work on the process plug 03. At the same time, the pressure in the steam chamber 02 in the prior art is replaced by the pressure in the steam chamber process plug pressure tool 01 (i.e., the pressure cavity formed by the first connecting hole 101, the second connecting hole 102 and the third connecting hole 204), which can significantly reduce the volume of the pressure cavity. Even if the pressure is released due to improper operation, the impact on personal and equipment safety can be reduced to a large extent.

[0057] like Figure 6 As shown, in a specific embodiment of the present utility model, the preload member is a cavity wall push rod 300, and the adapter two-way block 100 is provided with a push rod connecting screw hole 103. The first end of the cavity wall push rod 300 is a push rod threaded portion 301 that is threadedly matched with the push rod connecting screw hole 103. By adjusting the matching depth between the push rod threaded portion 301 and the push rod connecting screw hole 103, the length of the steam chamber process plug pressing tool 01 can be adjusted, and then adapted to steam chambers 02 of various sizes. It should be noted that the steam chamber process plug pressing tool 01 can also be configured with cavity wall push rods 300 of various lengths to further improve the adaptability to steam chambers 02 of different sizes. In addition, by adjusting the matching depth between the push rod threaded portion 301 and the push rod connecting screw hole 103, the force of the steam chamber process plug pressing tool 01 acting on the cavity wall of the steam chamber 02 can also be adjusted, which greatly solves the sealing problem between the process plug pressing head 200 and the cavity wall.

[0058] The second end of the cavity wall push rod 300 is a push rod abutting portion 303 that abuts against the cavity wall of the steam chamber 02. Specifically, the end of the push rod abutting portion 303 can be a convex curved surface, such as a cylindrical curved surface or a spherical surface. In this embodiment, the end of the push rod abutting portion 303 is designed to be a convex curved surface, which can significantly reduce the contact area between the push rod abutting portion 303 and the steam chamber 02, so that the abutment between the push rod abutting portion 303 and the steam chamber 02 is more secure and more stable, and the smaller contact area can reduce the degree of damage to the cavity wall caused by excessive pressing force, and the smooth curved surface can protect the cavity wall surface.

[0059] Further, in order to facilitate the rotation of the cavity wall push rod 300 to adjust the matching depth between the push rod threaded portion 301 and the push rod connecting screw hole 103, in this embodiment, the cavity wall push rod 300 also includes a first tightening tool matching portion 302 located between the push rod threaded portion 301 and the push rod abutment portion 303, and the outer surface of the first tightening tool matching portion 302 is a profile structure for matching with the tightening tool. For example, the tightening tool can be a wrench, and the first tightening tool matching portion 302 can be designed as a hexagonal prism or a quadrangular prism structure to match the wrench. It can be understood by those skilled in the art that the structure of the outer surface of the first tightening tool matching portion 302 can be designed according to the matching tightening tool, as long as it can be clamped by the tightening tool to drive the cavity wall push rod 300 to rotate.

[0060] In order to reduce the sealing requirements, in this embodiment, the push rod connecting screw hole 103 is disconnected from the first connecting hole 101 and the second connecting hole 102. The push rod connecting screw hole 103 is not connected with the first connecting hole 101 and the second connecting hole 102, so the pressure of the pressure pump will not act on the push rod connecting screw hole 103. Therefore, the connection between the push rod threaded portion 301 and the push rod connecting screw hole 103 does not need to be sealed.

[0061] In order to facilitate the transmission of force, the push rod connecting screw hole 103 and the second connecting hole 102 are arranged coaxially, that is, the axis of the push rod connecting screw hole 103 and the axis of the second connecting hole 102 are located on the same straight line, and the cavity wall push rod 300 connected to the push rod connecting screw hole 103 and the process plug pressing head 200 connected to the second connecting hole 102 are also located on the same straight line. The cavity wall push rod 300 and the process plug pressing head 200 are two components that contact the steam chamber process plug pressing tool 01 and the steam chamber 02. The two are located on the same straight line, which can make the steam chamber process plug pressing tool 01 receive the reaction force of the steam chamber 02 and be located on the same straight line, avoiding the torque generated by the two forces not being located on the same straight line, which has an adverse effect on the fixation of the steam chamber process plug pressing tool 01 in the steam chamber 02.

[0062] Please combine Figure 4 and Figure 5As shown, in a specific embodiment of the utility model, the second connecting hole 102 can also be a threaded hole, and the first end of the process plug pressing head 200 is a pressing head threaded portion 201 that is threadedly matched with the second connecting hole 102. It should be noted that part of the structure of the second connecting hole 102 is a threaded hole, and the remaining part is a light hole, that is, after the pressing head threaded portion 201 is assembled with the second connecting hole 102, it cannot completely occupy the entire space of the second connecting hole 102, and a part (that is, the part of the light hole) is reserved for convenient transmission of air pressure. Of course, the second connecting hole 102 can also be entirely threaded holes, and the length of the pressing head threaded portion 201 is designed to be less than the length of the second connecting hole 102, so that after the pressing head threaded portion 201 is assembled with the second connecting hole 102, it cannot completely occupy the entire space of the second connecting hole 102, and a part (that is, the part of the threaded hole that is not matched with the pressing head threaded portion 201) is reserved for convenient transmission of air pressure.

[0063] The second end of the process plugging head 200 is the pressing head abutting portion 203, which is sealed against the inner wall of the steam chamber 02. In this embodiment, the pressing head abutting portion 203 can be designed as a frustum structure, and the outer diameter of the pressing head abutting portion 203 gradually decreases from one end close to the pressing head threaded portion 201 to the end away from the pressing head threaded portion 201. In this embodiment, the process plugging head 200 is designed as a frustum structure, and the small diameter end is set at the end of the pressing head threaded portion 201 to reduce the contact area between the process plugging head 200 and the steam chamber 02, so as to facilitate sealing; at the same time, it can also ensure that the root of the process plugging head 200 has a larger area to avoid the root of the process plugging head 200 from breaking due to stress concentration under the action of a larger pressing force.

[0064] Furthermore, in order to facilitate the rotation of the process plug pressing head 200 to disassemble and assemble the process plug pressing head 200, in this embodiment, the process plug pressing head 200 also includes a second tightening tool matching portion 202 located between the pressing head threaded portion 201 and the pressing head abutment portion 203, and the outer surface of the second tightening tool matching portion 202 is a profile structure for matching with the tightening tool. For example, the tightening tool can be a wrench, and the second tightening tool matching portion 202 can be designed as a hexagonal prism or a quadrangular prism structure to match the wrench. It can be understood by those skilled in the art that the structure of the outer surface of the second tightening tool matching portion 202 can be designed according to the matching tightening tool, as long as it can be clamped by the tightening tool to drive the process plug pressing head 200 to rotate.

[0065] In a specific embodiment of the present invention, the second connecting hole 102 is an internal conical threaded hole, and the pressing head threaded portion 201 is an external conical threaded portion. Since the conical thread has better sealing properties, in this embodiment, the second connecting hole 102 and the pressing head threaded portion 201 are designed as conical threads, which helps to seal between the two.

[0066] In a specific embodiment of the present utility model, the first communicating hole 101 includes a first connecting hole portion and a first communicating hole portion, and the second communicating hole 102 includes a second connecting hole portion (a threaded hole portion of the second communicating hole 102) and a second communicating hole portion. The first communicating hole portion and the second communicating hole portion are connected, that is, the first communicating hole 101 and the second communicating hole 102 are connected through the connection between the first communicating hole portion and the second communicating hole portion.

[0067] The first connecting hole is used to connect the pressure pump, and the second connecting hole is used to connect the pressure head threaded portion 201. The aperture of the first connecting hole is smaller than that of the first connecting hole, and the aperture of the second connecting hole is smaller than that of the second connecting hole, which effectively saves the internal volume space of the adapter two-way block 100. If pressure relief spray occurs, the risk of injury can also be reduced due to the smaller aperture of the pressure chamber. It should be noted that the apertures of the first connecting hole and the second connecting hole can be designed to be the same, or they can be designed to be different according to needs; accordingly, the apertures of the first connecting hole and the second connecting hole can be designed to be the same, or they can be designed to be different according to needs.

[0068] In order to facilitate the connection between the first connecting hole 101 and the pressure pump, a pressure pump connector for connecting with the pressure pump can be provided on the first connecting hole 101. For example, part of the first connecting hole 101 can be designed as a threaded hole (for example, the first connecting hole portion can be designed as a threaded hole), and the pressure pump connector is threadedly fitted on the first connecting hole 101, so that the pressure pump connector can be quickly installed.

[0069] When the process plug 03 is subjected to a pressure test, first apply an anti-bite agent (i.e., a lubricant) to the push rod threaded portion 301 of the cavity wall push rod 300, and screw the push rod threaded portion 301 into the push rod connecting screw hole 103 of the adapter two-way block 100. Apply sealant to the pressing head threaded portion 201 of the process plug pressing head 200, screw it into the second connecting hole 102 of the adapter two-way block 100, and tighten it. Place the entire assembly horizontally in the steam chamber, align it with the plug hole in the cavity wall, and by adjusting the cavity wall push rod 300, press the pressing head abutment portion 203 of the process plug pressing head 200 against the process hole in the steam chamber 02 to achieve a sealing effect. Use a pressure pump to connect the first connecting hole 101 of the adapter two-way block 100 to perform pressure and pressure-maintaining operations.

[0070] The embodiment of the utility model further discloses a steam chamber process plugging and suppressing system, which includes a suppressing pump and the steam chamber process plugging and suppressing tool 01 disclosed in the above embodiment, and the suppressing pump is connected to the first connecting hole 101 of the steam chamber process plugging and suppressing tool 01. The steam chamber process plugging and suppressing system disclosed in the embodiment of the utility model has all the technical effects of the above steam chamber process plugging and suppressing tool because it has the above steam chamber process plugging and suppressing tool, which will not be described in detail herein.
