Description

Technical Field

[0001] The present application belongs to the technical field of pressure regulating towers, and more specifically, relates to a pressure regulating tower maintenance structure. Background Art

[0002] A pressure regulating tower is a pressure regulating device usually installed in a pipeline system to regulate and control gas pressure.

[0003] In the related art, a manhole and an inlet and outlet pipe are usually provided at the top of the pressure regulating tower. The manhole mainly includes a short cylinder section (or short pipe) welded on the top of the pressure regulating tower, and a flange blind plate is installed on the top of the short cylinder section (or short pipe) through a flange. By removing the flange blind plate, the staff can enter and exit the interior of the pressure regulating tower to perform maintenance work on the pressure regulating tower. The inlet and outlet pipes are generally straight pipes or 180° elbows welded on the top of the regulating tower, which are used to connect the pressure regulating tower to the atmosphere.

[0004] In actual use, when the inlet and exhaust pipes are set as straight pipes, affected by the environment, sand and debris are easy to fall into the pressure regulating tower along the straight pipes, polluting the medium in the tower. When the inlet and exhaust pipes are set as 180-degree elbows, due to the large curvature radius of the 180-degree elbow, the 180-degree elbow occupies too much space on the top of the pressure regulating tower, which is easily restricted by the scene; in addition, the setting of the 180-degree elbow also makes the top operating space of the pressure regulating tower, which is already equipped with a manhole, more limited, affecting the high-altitude operation on the top of the pressure regulating tower. Utility Model Content

[0005] In response to the defects or improvement needs of the prior art, the present application provides a pressure regulating tower maintenance structure, which aims to reduce the space at the top of the pressure regulating tower occupied by manholes and air inlet and exhaust pipes, and prevent wind, sand and debris from easily entering the interior of the pressure regulating tower.

[0006] The present application provides a pressure regulating tower maintenance structure, which specifically includes a short maintenance pipe and an inlet and outlet pipe, wherein:

[0007] The inspection short pipe is connected to the top of the pressure regulating tower, and a switch structure for opening and closing the inspection port is provided at the top inspection port of the inspection short pipe;

[0008] One end of the inlet and exhaust pipe is connected to the circumferential surface of the inspection short pipe, and the other end has an inlet and exhaust port opening downward. The inlet and exhaust pipe and the inspection short pipe form an inlet and exhaust channel connecting the inner cavity of the pressure regulating tower and the external atmosphere.

[0009] Through the above technical scheme conceived by the present application, compared with the prior art, the intake and exhaust pipes and the inspection short pipe in the present design are connected as one, and the inspection short pipe serves as a part of the intake and exhaust passage, so that the intake and exhaust pipes do not need to be bent 180 degrees to make the intake and exhaust ports face downward. This design reduces the top space of the pressure regulating tower occupied by the intake and exhaust pipes and the inspection short pipe (i.e., the manhole), making it difficult for wind, sand and debris to enter the interior of the pressure regulating tower, while also saving materials for the inspection structure.

[0010] In addition, the inlet and exhaust pipes in this design are connected to the side of the maintenance short pipe, and the inlet and exhaust pipes do not need to be independently welded to the top of the pressure regulating tower. This design can reduce the number of openings in the pressure regulating tower. In addition, the staff can pre-connect the maintenance short pipe with the inlet and exhaust pipes on the ground, saving the amount of high-altitude construction work on the top of the tower.

[0011] As a further preference, the inlet and exhaust pipes are 90-degree elbows, obtuse-angle elbows, or acute-angle elbows.

[0012] As a further preference, the air inlet and exhaust pipes are circular pipes or polygonal pipes.

[0013] As a further preference, a filter structure covering the inlet and outlet ports is fixed to the end of the inlet and outlet pipes.

[0014] As a further preference, the inlet and exhaust pipes are connected to one or more on the circumferential surface of the inspection short pipe.

[0015] As a further preference, the inspection short pipe is eccentrically arranged at the top of the pressure regulating tower, and the air inlet and outlet pipes are located at an end of the inspection short pipe away from the center of the top of the pressure regulating tower.

[0016] As a further preference, the top of the inspection short pipe protrudes circumferentially to form an annular flange for mounting the switch structure.

[0017] As a further preferred embodiment, the switch structure comprises a cover plate, one end of which is hinged to the top of the short inspection tube, and the other end of which is fixed to the short inspection tube via a connecting piece.

[0018] As a further preference, the cover plate can be flipped over to fit onto the protective structure at the top of the voltage regulating tower, and fixed to the protective structure via the connecting piece.

[0019] As a further preference, a handle is provided on the cover plate.

[0020] In general, the above technical solutions conceived by this application have the following technical advantages compared with the prior art:

[0021] 1. The inlet and exhaust pipes are connected to the inspection short pipe as a whole. The inspection short pipe acts as a part of the inlet and exhaust passage, so that the inlet and exhaust pipes do not need to be bent 180 degrees to make the inlet and exhaust ports face downward. This design reduces the top space of the pressure regulating tower occupied by the inlet and exhaust pipes and the inspection short pipe (i.e., the manhole), and makes it difficult for wind, sand and debris to enter the interior of the pressure regulating tower.

[0022] 2. The pipe type, bending angle and number of the inlet and exhaust pipes in this design can be adjusted according to the usage scenario and the inlet and exhaust demand of the pressure regulating tower, and the form is flexible and changeable.

[0023] 3. In the traditional solution, it is necessary to remove multiple bolts and move the flange blind plate to open the inspection port, which is inconvenient and cumbersome. In this design, when the inspection port needs to be opened, the locking state of the cover plate and the inspection short pipe is released by unfastening the connector, and then the inspection port of the inspection short pipe is opened by rotating the cover plate, so that the staff can perform maintenance inside the pressure regulating tower, which is more convenient to operate.

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The present application embodiment discloses a pressure regulating tower maintenance structure. Figure 1-3 The maintenance structure of the pressure regulating tower includes a maintenance short pipe 1 and an inlet and exhaust pipe 2. The maintenance short pipe 1 is connected to the top of the pressure regulating tower 10, and a switch structure for opening and closing the maintenance port is provided at the top of the maintenance short pipe 1; one end of the inlet and exhaust pipe 2 is connected to the circumferential surface of the maintenance short pipe 1, and the other end has an inlet and exhaust port opening downward, and the inlet and exhaust pipe 2 and the maintenance short pipe 1 form an inlet and exhaust channel connecting the inner cavity of the pressure regulating tower 10 and the outside atmosphere.

[0037] Since the inlet and exhaust pipes 2 are connected to the side of the inspection short pipe 1, and the inlet and exhaust ports of the inlet and exhaust pipes 2 face downward, in this design, the inlet and exhaust pipes 2 and the inspection short pipe 1 are integrated into one body, and the inspection short pipe 1 serves as a part of the inlet and exhaust passage, reducing the top space of the pressure regulating tower 10 occupied by the inlet and exhaust pipes 2 and the inspection short pipe 1, so that sand and debris are not easy to enter the interior of the pressure regulating tower 10.

[0038] Furthermore, the pipe type of the inlet and exhaust pipe 2 can be diversified. For example, the inlet and exhaust pipe 2 can be a round pipe or a polygonal pipe (such as a rectangular pipe), as long as it can be used for the inlet and exhaust of the pressure regulating tower 10. The material of the inlet and exhaust pipe 2 can be selected from metal or plastic.

[0039] Furthermore, the bending angle of the inlet and exhaust pipe 2 can be selected in various ways according to the needs. For example, the inlet and exhaust pipe 2 can be selected as a 90-degree elbow, an obtuse elbow, or an acute elbow, as long as the inlet and exhaust ports at the ends thereof face downward.

[0040] Furthermore, the number of connections of the intake and exhaust pipes 2 on the circumferential surface of the inspection short pipe 1 can be set to one or more, and the diameter of the pipe openings of the intake and exhaust pipes 2 can be selected according to the scene space conditions.

[0041] That is, in the actual construction process, the pipe type, bending angle, number, pipe mouth diameter, and material of the intake and exhaust pipe 2 can be selected and designed according to the scene space conditions on site and the intake and exhaust requirements of the pressure regulating tower 10, so as to improve the intake and exhaust pipe 2 in the traditional straight pipe form or 180-degree bend pipe form. The existing problems such as being too large in diameter, easily restricted by the scene, being too bulky, and inconvenient to operate.

[0042] In addition, in some embodiments, a filter structure (not shown in the figure) covering the inlet and outlet ports may be fixed at the end of the inlet and outlet pipes. ， For example, a filter screen is covered on the inlet and outlet ports of the inlet and outlet pipes 2, an end cover with filter holes is installed, a filter plate with filter holes is welded, etc., to further prevent dust and debris.

[0043] In addition, the positions of the inspection short pipe 1 and the air inlet and outlet pipes 2 at the top of the tower can also be adjusted according to actual conditions to facilitate the workers to perform operations at the top of the tower. For example, the inspection short pipe 1 is eccentrically arranged at the top of the pressure regulating tower 10, and the air inlet and outlet pipes 2 are located at the end of the inspection short pipe 1 away from the center of the top of the pressure regulating tower 10; under this design, the open space at the top of the inspection tower is large, which can leave enough construction space for the workers and can leave enough installation space for other equipment or structures that may exist at the top of the pressure regulating tower 10.

[0044] Furthermore, for ease of understanding, Figure 4-6 Three embodiments of the intake and exhaust pipe 2 are shown. Figure 4 Taking the scheme shown in the figure as an example, the number of the inlet and exhaust pipes 2 can be one or more. When the number of the inlet and exhaust pipes 2 is one, the top view of the inlet and exhaust pipes 2 and the inspection short pipe 1 with the cover plate 3 can be as follows Figure 7 When the number of the inlet and exhaust pipes 2 is two, the top view of the inlet and exhaust pipes 2 and the inspection short pipe 1 with the cover plate 3 can be as follows Figure 8 As shown. It is understandable that Figure 5 and Figure 6 The number of the intake and exhaust pipes 2 in the illustrated embodiment can also be set according to the same principle.

[0045] Further, such as Figure 2 As shown, in the inspection short tube 1, in order to facilitate the installation of the switch structure, the top of the inspection short tube 1 protrudes along the circumferential direction to form an annular flange 1-1 for installing the switch structure.

[0046] Further, the switch structure can be selected as a cover plate 3, a blind plate, etc.; in order to facilitate the maintenance work of the staff, in this embodiment, Figure 1-3 As shown, the switch structure includes a cover plate 3, one end of which is hinged to the top of the inspection short pipe 1, preferably hinged to the annular flange 1-1 at the top, and the other end of the cover plate 3 is fixed to the inspection short pipe 1 through a connector. Specifically, one end of the cover plate 3 and the inspection short pipe 1 are hinged, including but not limited to, by a hinge 4; the other end of the cover plate 3 is provided with a handle 5, and the cover plate 3 and the inspection short pipe 1 are locked and fixed by the connector.

[0047] Furthermore, the connector includes but is not limited to a lock, for example, the connector can be selected as a chain, a buckle, etc. When in use, the cover plate 3 is fixed to the inspection short pipe 1 by the lock to prevent the cover plate 3 from being opened. When maintenance is required, the lock can be unlocked first, and then the cover plate 3 can be flipped open for the staff to perform maintenance inside the surge tower 10. Among them, the lock is a prior art, preferably a ring / D-shaped lock, etc., which is not shown in the figure.

[0048] Preferably, a handle or a positioning ring or other hole structure is welded on the outer edge of the annular flange 1-1 of the inspection short pipe 1. When the cover plate 3 closes the inspection port, the handle 5 on the cover plate 3 is close to the hole structure on the inspection short pipe 1, and the lock buckle is used to lock the handle 5 on the cover plate 3 and the hole structure on the inspection short pipe 1.

[0049] Furthermore, when the top of the surge tower 10 has a protective structure 20 such as a guardrail, the hinge between the cover plate 3 and the inspection short pipe 1 is set at one end of the cover plate 3 near the protective structure 20. Under this design, when the surge tower 10 needs to be inspected and maintained, the lock is first unlocked, and then the cover plate 3 is flipped open, and the cover plate 3 is flipped to fit the protective structure 20 at the top of the surge tower 10, and the cover plate 3 is connected to the protective structure 20 through the connector at the handle 5 to prevent the cover plate 3 from falling back.
