Description

Technical Field

[0001] This invention relates to the field of gas pressure regulating equipment technology, and in particular to a portable gas building pressure regulating box. Background Technology

[0002] A gas pressure regulator, also known as a pressure reducing valve or gas pressure regulating valve, is a device that automatically changes the flow rate of gas passing through a regulating valve to maintain a specified outlet gas pressure. It is generally divided into two types: direct-acting and indirect-acting.

[0003] During maintenance, the gas pipeline needs to be connected to a temporary gas pressure regulator first, and then the gas pressure regulator on the gas transmission pipeline needs to be inspected and repaired. After the inspection and repair are completed, it needs to be reconnected. Therefore, maintenance personnel often need to carry the heavy temporary gas pressure regulator to the maintenance site for work. The following problems exist during the maintenance process: Because the temporary gas pressure regulator is inconvenient to carry, it usually takes two people to carry the equipment to the maintenance site, which is time-consuming and labor-intensive, and prolongs the entire maintenance and repair time. Summary of the Invention

[0004] The purpose of this invention is to provide a portable gas building pressure regulating box, which solves the problem that in the prior art, temporary gas pressure regulators are inconvenient to carry, so two people are usually needed to carry the equipment to the maintenance site, which is time-consuming and labor-intensive, and prolongs the entire maintenance time.

[0005] To achieve the above objectives, the present invention provides a portable gas building pressure regulating box, including a box body, a pressure regulating mechanism inside the box body, a lifting mechanism on the top of the outer side, and an adjustment mechanism; The adjustment mechanism includes a support tube, an adjustment rod, a locking pin, a locking sleeve, a guide plate, and a sealing device. Multiple support tubes are installed at the bottom of the left and right sides of the housing. The adjustment rod is slidably connected to and passes through the support tube. The locking pin passes through both the support tube and the adjustment rod and is slidably connected to the guide plate. The locking sleeve is screwed onto the locking pin and abuts against the support tube. The guide plate is installed on the housing, and the sealing device is located on the front side of the housing.

[0006] The pressure regulating mechanism includes a pressure regulator body and metal hoses. The pressure regulator body is installed inside the housing, and two metal hoses are installed on its working pipeline.

[0007] The lifting mechanism includes a lifting rod and a limiting plate, wherein the lifting rod is detachably connected to the limiting plate; and the limiting plate is detachably connected to the box body.

[0008] The locking pin is provided with a handle and a guide bar. The handle is integrally formed with the locking pin and a return spring is provided between it and the guide plate. The guide bar is integrally formed with the locking pin and is slidably connected to the guide plate and is symmetrically arranged.

[0009] The locking sleeve has a snap-fit ​​part on its outer side, which can be square or hexagonal.

[0010] The sealing device includes a door and a lock. The door is rotatably mounted on the front side of the box body, and the lock is located on the left side of the door.

[0011] The portable gas building pressure regulating box also includes an observation component, which includes a transparent plate and a pressure plate. The transparent plate is installed on the front side of the box door and is limited by the pressure plate; the pressure plate is detachably connected to the box door.

[0012] This invention discloses a portable gas building pressure regulating box. During use, the box can be moved directly via a lifting mechanism, thus moving the pressure regulating mechanism. Furthermore, the flanges at the inlet and outlet of the pressure regulator are replaced with elbows, and a metal hose is connected to the elbow. During on-site connection, only the other end of the metal hose needs to be connected to the gas pipeline, facilitating connection and saving maintenance time.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Example 1: like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a portable gas building pressure regulating box. Figure 2 This is a structural diagram of the locking pin. Figure 3 This is a front view of the housing. The present invention provides a portable gas building pressure regulating box: it includes a housing 101, a pressure regulating mechanism, a lifting mechanism, and an adjusting mechanism. The adjusting mechanism includes a support pipe 102, an adjusting rod 103, a locking pin 104, a locking sleeve 105, a guide plate 106, and a sealing device. The pressure regulating mechanism includes a pressure regulator body 107 and a metal hose 108. The lifting mechanism includes a lifting rod 109 and a limiting plate 110. The sealing device includes a door 114 and a door lock 115. This solution solves the problem in the prior art where temporary gas pressure regulators are inconvenient to carry, generally requiring two people to lift the equipment to the maintenance site, which is time-consuming and labor-intensive, extending the overall maintenance time. Understandably, the aforementioned solution facilitates faster maintenance.

[0022] In this embodiment, a pressure regulating mechanism is provided inside the housing 101, and a lifting mechanism is provided on the top outer side. Furthermore, the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this invention does not involve improvements to the software or methods. Finally, all corresponding components in this application can be fixed by bolts from the inside out.

[0023] Multiple support tubes 102 are installed at the bottom of the left and right sides of the housing 101. An adjusting rod 103 is slidably connected to and passes through the support tube 102. A locking pin 104 passes through both the support tube 102 and the adjusting rod 103, and is slidably connected to the guide plate 106. A locking sleeve 105 is screwed onto the locking pin 104 and abuts against the support tube 102. The guide plate 106 is installed on the housing 101. A sealing device is located on the front side of the housing 101. The support tube 102 has a vertically oriented through-slide groove for the adjusting rod 103, and the adjusting rod 103 has multiple adjusting holes. A through-hole adjusting hole is located at the top of the support tube 102. The locking pin 104 has a stepped external thread end for easy installation of the locking sleeve 105. The guide plate 106 is slidably engaged with the locking pin 104. The sealing device enhances safety. When the adjusting rod 103 is in the adjusted position, the rear end face of the housing 101 can be in contact with the ground, making it convenient for one person to adjust. At this time, the corresponding pipes are not connected. After adjusting to the required height, the housing 101 is set vertically and then connected. Anti-slip plates can be installed on the bottom of the multiple adjusting rods 103 to improve stability.

[0024] Secondly, the regulator body 107 is installed inside the housing 101, and two metal hoses 108 are installed on its working pipeline. In use, the housing 101 is moved to the testing site, the housing door 114 is opened, and the other end of the metal hose 108 is connected to the gas pipeline to replace the original gas regulator. The original gas regulator is then inspected and maintained, and the pipeline is reconnected afterward. The auxiliary equipment such as filters that work in conjunction with the regulator body 107 are not fully shown in the accompanying drawings.

[0025] Then, the lifting rod 109 is detached from the limiting plate 110; the limiting plate 110 is detached from the box body 101. The limiting plate 110 is provided with mating holes for mounting the stepped ends of the lifting rod 109 on both sides.

[0026] Furthermore, the handle 111 is integrally formed with the locking pin 104, and a return spring 113 is provided between it and the guide plate 106; the guide strip 112 is integrally formed with the locking pin 104 and slidably connected to the guide plate 106, and is symmetrically arranged. The handle 111 facilitates the pulling and sliding of the locking pin 104. The return spring 113 is sleeved and installed on the outside of the locking pin 104. The guide strip 112 prevents the locking pin 104 from rotating.

[0027] Furthermore, the locking sleeve 105 has a snap-fit ​​portion on its outer side, which can be square or hexagonal. This structure facilitates the installation or removal of the locking sleeve 105.

[0028] Finally, the cabinet door 114 is rotatably mounted on the front side of the cabinet body 101; the door lock 115 is located on the left side of the cabinet door 114. The cabinet door 114 is installed by a hinge, and the door lock 115 is used to close and lock the cabinet door 114.

[0029] In addressing the problem that existing temporary gas pressure regulators are inconvenient to carry, requiring two people to lift them to the maintenance site, which is time-consuming and labor-intensive, extending the overall maintenance time, this invention allows the lifting mechanism to move the housing 101, thereby moving the pressure regulating mechanism. Furthermore, the flanges at the inlet and outlet ends of the pressure regulator body 107 are replaced with elbow connectors, and the metal hose 108 is connected to the elbow connector. During on-site connection, only the other end of the metal hose 108 needs to be connected to the gas pipeline, facilitating connection and further saving maintenance time. Finally, the position of the adjusting rod 103 can be adjusted using the locking pin 104 to adjust the working height of the housing 101, adapting to various environments. This solves the problem of existing temporary gas pressure regulators being inconvenient to carry, requiring two people to lift them to the maintenance site, which is time-consuming and labor-intensive, extending the overall maintenance time.

Based on the first embodiment, the present invention provides a portable gas building pressure regulating box, which further includes an observation component, including a transparent plate 201 and a pressure plate 202.

[0031] The transparent panel 201 is installed on the front side of the cabinet door 114 and is limited by the pressure plate 202; the pressure plate 202 is detachably connected to the cabinet door 114. A stepped groove is provided on the cabinet door 114 to facilitate the installation of the transparent panel 201. The transparent panel 201 can be made of high-strength tempered glass or transparent acrylic sheet, etc. The inner rectangular frame of the pressure plate 202 is slightly larger than the outer rectangular frame of the transparent panel 201.

[0032] In this embodiment, the transparent plate 201 structure facilitates internal observation.

[0033] Example 3: like Figure 5 As shown, where Figure 5This is a schematic diagram of the filter plate. Based on the first embodiment, the present invention provides a portable gas building pressure regulating box. The portable gas building pressure regulating box also includes a ventilation mechanism, which includes a ventilation pipe 301, a filter plate 302, and a limiting member 303.

[0034] The ventilation duct 301 is installed symmetrically within the ventilation opening of the housing 101 and is T-shaped. The filter plate 302 is installed within the ventilation duct 301 via the limiting member 303. The disc of the ventilation duct 301 is fixed with bolts.
