Description

Technical Field

[0001] This utility model relates to the technical field of thermal pressure detection and early warning devices, and more specifically to a heating station heating pressure detection and early warning device. Background Technology

[0002] Heating pipe networks, also known as heating pipelines, are heating pipes that run from boiler rooms, direct-fired turbine rooms, heating centers, etc., from heat sources to the heating inlets of buildings. Heating pipes inherently possess a certain water pressure. When water is heated, it evaporates to form steam and expands due to heat. The pressure within the heating pipes must be ensured to not exceed the pipe's withstand pressure to prevent pipe ruptures and leaks. Pressure transmitters are typically used to monitor the pressure within the pipes.

[0003] According to announcement number CN221375417U, announcement date: July 19, 2024, a heating pipeline internal pressure detection device is disclosed, relating to the technical field of heating pipeline pressure detection devices. It includes mounting blocks symmetrically connected to the outer periphery of a pressure transmitter mounting pipe. A rotating structure is rotatably mounted on the mounting blocks, and a protective cover is slidably mounted on the rotating structure. Two protective covers can be assembled into a protective cylinder that is slidably fitted onto the pressure transmitter mounting pipe. This utility model, through the design of the pressure transmitter, protective covers, and rotating structure, allows the protective covers to be assembled into a protective cylinder, which is fitted onto the pressure transmitter mounting pipe. This protects the connection between the pressure transmitter mounting pipe and the tee pipe, reducing the rate of rust-preventive oil evaporation and minimizing oxidation and corrosion at the pipe connection due to prolonged contact with air caused by excessively rapid evaporation of the rust-preventive oil, thereby preventing leaks.

[0004] In the prior art, including the aforementioned patent, the pressure transmitter uses a tee installed in the middle of the heating pipeline to allow the detection end of the pressure transmitter to extend into the heating pipeline to detect the pressure of the heating pipeline. However, since the pressure transmitter and the heating pipeline are fixedly installed, the detection end of the pressure transmitter is easily damaged due to the high temperature and high pressure working environment, which makes it difficult to disassemble and replace the detection end of the pressure transmitter if it is damaged.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] like Figure 1-6 As shown, a heating station heating pressure detection and early warning device includes an installation pipe 1 and a mounting base 2. The installation pipe 1 has a flow hole 11 and a connecting hole 111 that are interconnected. The installation pipe 1 is provided with an installation part 12, and the installation part 12 has an insertion groove 121. The mounting base 2 is fixedly installed with a detector 3 and a buzzer 4. The mounting base 2 is installed in the insertion groove 121 by locking bolts 9 so that the detection end 31 of the detector 3 extends into the connecting hole 111, and the mounting base 2 separates the flow hole 11 and the insertion groove 121.

[0024] Specifically, such as Figure 1 As shown, both ends of the installation pipe 1 are provided with connection parts 13 that connect to the heating pipe, such as... Figure 2 and Figure 6 As shown, the detector 3 and buzzer 4 are first installed on the mounting base 2. The mounting base 2 has a through hole 21. The locking bolt 9 is bolted into the insertion groove 121 through the through hole 21 so that the detection end 31 of the detector 3 can be inserted into the connecting hole 111 to achieve detection. The buzzer 4 is located in the insertion groove 121. When the pressure detected by the detector 3 is too high, the buzzer 4 will sound to provide timely warning and improve the safety of use. When the detector 3 needs to be replaced, the locking bolt 9 can be directly rotated to remove the mounting base 2 from the insertion groove 121, so as to repair or replace the detector 3, thereby improving the convenience of disassembly and installation of the detector 3.

[0025] In the above technical solution, the locking bolt 9 is bolted into the mounting slot 121 through the through hole 21 so that the detection end 31 of the detector 3 can be inserted into the connecting hole 111 to achieve detection. The buzzer 4 is located in the mounting slot 121. When the pressure detected by the detector 3 is too high, the buzzer 4 will sound to provide timely warning and improve the safety of use. When the detector 3 needs to be replaced, the locking bolt 9 can be directly rotated to remove the mounting base 2 from the mounting slot 121, so as to repair or replace the detector 3 and improve the convenience of disassembly and installation of the detector 3.

[0026] As a further embodiment of this utility model, a first stepped ring 15 is provided in the connecting hole 111, and an annular abutment 22 is provided on the mounting base 2. The mounting base 2 is installed in the insertion groove 121 to abut against the first stepped ring 15, and the annular abutment 22 abuts against the groove on the first stepped ring 15.

[0027] Specifically, such as Figure 2As shown, a first stepped ring 15 is provided in the connecting hole 111, and an annular abutment strip 22 is provided on the mounting base 2. When the mounting base 2 is installed in the mounting groove 121 by the locking bolt 9, the mounting base 2 abuts against the first stepped ring 15, and the annular abutment strip 22 abuts against the groove on the first stepped ring 15, thereby improving the sealing performance of the mounting base 2, preventing the leakage of the medium liquid in the connecting hole 111 from causing damage to the detector 3 or the buzzer 4, and improving the safety of use.

[0028] As a further embodiment of this utility model, it also includes a sealing seat 5 having a sealing part 51 and an extension part 52 thereon. The sealing seat 5 is axially slidably disposed on the mounting part 12. A second stepped ring 16 is disposed in the communicating hole 111 to form a detection chamber 112 within the communicating hole 111. The detection end 31 is located within the detection chamber 112. The sealing seat 5 is driven to slide axially so that the sealing part 51 abuts against the second stepped ring 16 to seal the detection chamber 112.

[0029] Specifically, such as Figure 6 As shown, the second stepped ring 16 is located in the connecting hole 111 to form a detection chamber 112. When the mounting base 2 is installed in the insertion groove 121, the detection end 31 of the detector 3 is located in the detection chamber 112. When the detector 3 is working normally, the sealing seat 5 slides axially away from the second stepped ring 16 so that the sealing part 51 does not contact the second stepped ring 16. At this time, the connecting hole 111 is connected to the detection chamber 112 so that the detection end 31 can be located in the detection chamber 112 to detect the pressure of the flow hole 11.

[0030] When it is necessary to disassemble and replace the detector 3, the sealing seat 5 is first driven to slide axially so that the sealing part 51 abuts against the second step ring 16 to seal the detection chamber 112. At this time, the detection chamber 112 is separated from the connecting hole 111 and the pressure is small. Then, the locking bolt 9 is removed to remove the mounting seat 2 from the loading groove 121, so that the detector 3 can be removed from the mounting tube 1 for replacement or maintenance. The medium liquid in the flow hole 11 of the mounting tube 1 will not spray out along the connecting hole 111, the detection chamber 112 and the loading groove 121, so that the heating pipeline does not need to cut off the medium liquid to reduce the internal pressure of the mounting tube 1, thus facilitating the quick disassembly and assembly of the detector 3.

[0031] As a further embodiment of this utility model, a sealing ring 511 is provided on the sealing part 51, and the sealing part 51 abuts against the second stepped ring 16 so that the sealing ring 511 abuts against the groove opened on the second stepped ring 16.

[0032] Specifically, such as Figure 6As shown, a sealing ring 511 is provided on the sealing part 51. The sealing part 51 abuts against the second stepped ring 16 so that the sealing ring 511 abuts against the groove opened on the second stepped ring 16, thereby improving the sealing performance of the sealing part 51 to the detection chamber 112, avoiding the problem of the medium liquid in the flow hole 11 overflowing outward through the detection chamber 112 and the loading groove 121 when the detector 3 is disassembled, and improving the safety of use.

[0033] As a further embodiment of this utility model, a drive rod 7 is symmetrically rotatably arranged on the mounting part 12, and a mating hole 523 is symmetrically opened on the extension part 52, and the drive rod 7 is threadedly engaged with the mating hole 523.

[0034] Specifically, such as Figure 2 As shown, the drive rod 7 is symmetrically and axially rotated on the rotating hole 14 of the mounting part 12. The drive rod 7 is threadedly engaged with the mating hole 523 of the sealing seat 5. The drive rod 7 can be manually driven to rotate at the same time. The drive rod 7 can drive the sealing seat 5 to slide axially through the threaded engagement, so that no additional tools are needed to drive the sealing seat 5, which is convenient for actual use and quick disassembly and assembly of the detector 3.

[0035] As a further embodiment of this utility model, it also includes a cover 6. The protruding part 52 has a through groove 522 for exposing the mounting base 2. The cover 6 is provided with a fixing part 62. The fixing part 62 has a receiving cavity 621 with both ends through it. The first end of the receiving cavity 621 is provided with a rubber membrane 8. The cover 6 is inserted into the protruding part 52 to cover the through groove 522. The fixing part 62 passes through the through groove 522 to cover the buzzer 4 in the receiving cavity 621.

[0036] Specifically, such as Figure 5 As shown, the shielding cover 6 is symmetrically provided with plug-in parts 61, and the sealing seat 5 is symmetrically provided with plug-in slots 521. The plug-in parts 61 can be inserted into the plug-in slots 521 to cover the through slots 522, preventing external liquids or impurities from falling into the loading slots 121 and causing damage to the buzzer 4 or detector 3, thus improving the protection of the buzzer 4 and detector 3. The fixing part 62 covers the buzzer 4 in the receiving cavity 621 to further limit, fix and protect the buzzer 4, preventing vibration damage to the buzzer 4 caused by the vibration of the heating pipeline. When the buzzer 4 works and generates sound waves, it will form a waveform vibration in the receiving cavity 621, causing the rubber diaphragm 8 to arch back and forth. Thus, while generating sound warning, it can also provide visual warning, quickly locate the location of excessive pipeline pressure, and improve the safety of use.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
