[0022] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0023] The present invention is further described in detail below with reference to the embodiments:

[0024] like Figure 1-4 As shown, the utility model provides a modular pressure relief valve, including a pressure relief module 1 and a pressure measuring module 2. Both sides of the pressure relief module 1 are fixedly connected with mounting pipes 7, and the end of the mounting pipe 7 away from the pressure relief module 1 is provided with a connecting component 3 connected thereto.

[0025] The connecting assembly 3 includes a fastening sleeve 9, the inner wall of the fastening sleeve 9 is movably connected to the outer wall of one end of the mounting tube 7, a positioning block ring 8 is fixedly connected to the outer wall of one end of the mounting tube 7 close to the fastening sleeve 9, the inner wall of one end of the fastening sleeve 9 is threadedly connected to the drain pipe 13, and the end of the mounting tube 7 close to the fastening sleeve 9 is plugged into the inner wall of one end of the drain pipe 13.

[0026] The pressure measuring module 2 is located on one side of the pressure relief module 1. A mounting groove 14 is provided on the top of the pressure measuring module 2. A pressure gauge 4 is threadedly connected to the inner wall of the mounting groove 14.

[0027] A water inlet pipe 15 is fixedly connected to a side of the pressure measuring module 2 away from the pressure relief module 1 .

[0028] The auxiliary rod 12 is inserted into the fastening tube 10, and then force is applied to the auxiliary rod 12 to move it. The auxiliary rod 12 forms a lever force on the fastening sleeve 9 through the fastening tube 10, so that the fastening sleeve 9 is rotated and detached from the drain pipe 13 and gradually approaches the pressure relief module 1. At this time, the connection between the pressure relief module 1 and the drain pipe 13 can be released. Thereafter, the same operation is performed on the pressure relief module 1 and the pressure measuring module 2, so that the pressure relief module 1 can be detached from the pressure measuring module 2, and then disassembled from the pipeline system without removing the pressure measuring module 2, thereby saving subsequent installation time.

[0029] The outer wall of the fastening sleeve 9 is fixedly connected to a disassembly cylinder 11 and a fastening cylinder 10. The fastening cylinder 10 and the disassembly cylinder 11 are arranged side by side in opposite directions on the outer wall of the fastening sleeve 9. The coordinated use of the installation pipe 7, the positioning block ring 8, the drain pipe 13, the fastening sleeve 9, the fastening cylinder 10, the disassembly cylinder 11 and the auxiliary insertion rod 12 allows for rapid docking of the installation pipe 7 and the drain pipe 13. At the same time, the lever effect formed by the auxiliary insertion rod 12 further facilitates the disassembly and installation work of the staff. Moreover, under the sealing effect of the fastening sleeve 9, the sealing of the connection between the installation pipe 7 and the drain pipe 13 can be guaranteed.

[0030] like Figure 1-4 As shown, based on Example 1, the present invention provides a technical solution: preferably, an auxiliary insertion rod 12 is movably inserted into the inner wall of the fastening cylinder 10 .

[0031] The outer wall of the pressure measuring module 2 is provided with a limiting groove 17 , the inner wall of the limiting groove 17 is plugged with the pressure gauge 6 , and the outer wall of the pressure measuring module 2 is fixedly connected with an auxiliary card 16 for limiting the pressure gauge 6 .

[0032] The outer wall of the pressure gauge 2 6 near the bottom is clamped with the inner wall of the auxiliary clamp 16.

[0033] A rotating disk 5 is fixedly connected to the outer wall of the pressure gauge 4 near the bottom end.

[0034] The following is a detailed description of the working principle of the modular pressure relief valve.

[0035] like Figure 1-4 As shown, when in use, when pressure gauge 1 4 fails and needs to be replaced, it is separated from the pressure measuring module 2, and pressure gauge 2 6 is removed from the auxiliary card 16. The pressure gauge 2 6 is docked with the pressure measuring module 2 and inserted into the installation slot 14, which can ensure the normal operation of the pressure measuring function in a very short time.

[0036] When the pressure relief module 1 needs to be replaced, the auxiliary rod 12 can be inserted into the fastening cylinder 10, and then the auxiliary rod 12 can be pushed and turned, and the lever force formed by the auxiliary rod 12 on the fastening sleeve 9 through the fastening cylinder 10 can be used to rotate the fastening sleeve 9 from the drain pipe 13 and gradually approach the pressure relief module 1. At this time, the connection between the pressure relief module 1 and the drain pipe 13 can be released, and then the same operation can be performed on the pressure relief module 1 and the pressure measuring module 2, so that the pressure relief module 1 can be detached from the pressure measuring module 2, and then disassembled from the pipeline system without removing the pressure measuring module 2, saving subsequent installation time. When installing the pressure relief module 1, first insert one end of the installation tube 7 into one end of the drain pipe 13. At this time, the positioning block ring 8 will abut against the end of the drain pipe 13. Then, the auxiliary insertion rod 12 is inserted into the disassembly cylinder 11, which drives the fastening sleeve 9 to reverse. The fastening sleeve 9 is connected to the drain pipe 13 by the thread action, and the sealing between the installation tube 7 and the drain pipe 13 is improved by the positioning block ring 8 and the installation tube 7. The lever effect formed by the auxiliary insertion rod 12 and the disassembly cylinder 11 can save labor and improve installation efficiency.

[0037] When the pressure measuring module 2 needs to be disassembled and separated, it can also be done in the same way as disassembling the fastening sleeve 9 .

[0038] It should be noted that, in this article, the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or still includes elements that are inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element. The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
