Description

Technical Field

[0001] This utility model relates to the field of heating system technology, specifically to a safety device for venting and depressurizing heating pipelines. Background Technology

[0002] In heating systems, changes in water temperature and system operation can cause abnormally high internal pressure, leading to safety hazards. Heating pipelines, also known as thermal pipeline networks, are a crucial component of the heating system. They originate from boiler rooms, direct-fired turbine rooms, heating centers, etc., and run from heat sources to the building's heating inlets. Multiple heating pipelines form a network. Generally, the design pressure for hot water is less than or equal to 2.5 MPa, and the design temperature is less than or equal to 200℃; the design pressure for steam is less than or equal to 1.6 MPa, and the design temperature is less than or equal to 350℃. To prevent damage or safety hazards caused by excessively high water pressure, pressure relief devices are typically installed on heating pipelines to release pressure and ensure the safe and stable operation of the heating system.

[0003] Traditional pressure relief devices are mostly simple mechanical structures, which are not sensitive enough and cannot monitor the pressure status in real time for automatic pressure relief, thus having certain limitations. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a heating pipeline venting and pressure relief safety device that can monitor the internal pressure of the heating pipeline in real time and automatically vent, relieve pressure, and sound an alarm when the pressure is abnormal, effectively improving the safety and reliability of the heating system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heating pipeline venting and pressure relief safety device includes a heating pipeline and a water storage tank installed on the heating pipeline. The inlet and outlet of the water storage tank are respectively connected to the heating pipeline to form an inlet pipe and an outlet pipe for the water storage tank. An electromagnetic pressure relief valve is installed on the outlet pipe.

[0007] One side of the water storage tank is connected to a connecting shell, and a pressure transmitter is installed inside the connecting shell to detect the pressure of the heating pipeline.

[0008] It also includes a controller, which is connected to the pressure transmitter and the electromagnetic pressure relief valve respectively, and is used to receive signals from the pressure transmitter and control the opening and closing of the electromagnetic pressure relief valve.

[0009] As a further implementation, the electromagnetic pressure relief valve is installed at the outlet of the water storage tank and connected to the return water tank. When the pressure in the heating pipeline is too high, the water in the heating pipeline can be released under the control of the controller to relieve the pressure, and the released water can be reused after entering the return water tank.

[0010] As a further implementation, a second valve is installed on the inlet pipe of the heating pipeline, and a first valve is installed on the outlet pipe. The second valve and the first valve control the opening and closing of the inlet pipe and outlet pipe of the water storage tank, respectively.

[0011] As a further implementation, an exhaust branch is provided between the first valve and the outlet of the water storage tank, and an automatic exhaust valve is provided on the exhaust branch to release the gas in the heating pipeline.

[0012] As a further implementation, a third valve is also provided on the exhaust branch. The third valve is installed between the water outlet pipe and the automatic exhaust valve to control the opening and closing of the exhaust branch, making it easy to disconnect the exhaust branch for maintenance and replacement of the automatic exhaust valve.

[0013] As a further implementation, a manual drain valve is installed at the lower outlet of the connecting shell for draining water during device maintenance.

[0014] As a further implementation, the connecting shell and the water storage tank are connected by a branch side pipe and a flange. The branch side pipe is provided with upper and lower branches to ensure that the temperature and pressure inside the connecting shell are the same as those inside the water storage tank.

[0015] As a further implementation, the heating pipe, exhaust branch, and branch side pipe are all welded from seamless stainless steel pipes.

[0016] As a further implementation, the water storage tank, the first valve, the second valve, the third valve, the connecting shell, and the manual drain valve are all made of stainless steel.

[0017] As a further implementation, an alarm device is provided on the outside of the connecting shell. The alarm device is connected to the controller and can issue an alarm when the system pressure is abnormal, reminding staff to deal with it in time and ensure system safety.

[0018] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses a pressure transmitter to detect the pressure of the heating pipeline in real time and sets up a controller to control the electromagnetic pressure relief valve. When the pressure transmitter shows an abnormal pressure, the controller can automatically open the pressure relief valve to release pressure, which effectively improves the safety and reliability of the heating system and ensures the stable operation of the heating system.

[0020] 2. This utility model is equipped with an exhaust branch, which can release the gas in the heating pipe through an automatic exhaust valve when the pressure in the heating pipe does not exceed the system's set operating pressure. The advantage is that it only exhausts the gas and does not drain the water, thus reducing the waste of hot water resources.

[0021] 3. This utility model has an alarm device on the outside of the connecting shell. The alarm device is connected to the controller and can issue an alarm when the system pressure is abnormal, reminding the staff to deal with it in time and ensuring the safe operation of the system.

[0031] One side of the water storage tank 2 is connected to a connecting shell 4, and a pressure transmitter 5 is installed inside the connecting shell 4 for detecting the pressure of the heating pipeline.

[0032] It also includes a controller 6, which is connected to the pressure transmitter 5 and the electromagnetic pressure relief valve 3 respectively, and is used to receive signals from the pressure transmitter and control the opening and closing of the electromagnetic pressure relief valve.

[0033] Specifically, such as Figure 1 As shown, the heating pipeline venting and pressure relief safety device of this embodiment includes a heating pipeline 1, a water storage tank 2, an electromagnetic pressure relief valve 3, a connecting housing 4, a controller 6, and a pressure transmitter 5. The water storage tank 2 and the electromagnetic pressure relief valve 3 are respectively installed on the heating pipeline 1. The inlet 21 and outlet 22 of the water storage tank 2 are respectively connected and fixedly connected to the heating pipeline 1 via flanges and bolts, forming the inlet and outlet pipelines of the water storage tank, facilitating disassembly and installation during maintenance and repair. The electromagnetic pressure relief valve 3 is installed on the outlet pipeline at the outlet 22 of the water storage tank. The electromagnetic pressure relief valve 3 is connected to the heating pipeline 1 via flanges and bolts. The outlet of the electromagnetic pressure relief valve 3 is connected to a return water tank through the heating pipeline, allowing the release of water from the heating pipeline for pressure relief. The released water can be reused after entering the return water tank.

[0034] In this embodiment, a first valve 7 is also provided on the outlet pipe of the water storage tank 2. The first valve 7 is installed on the heating pipe between the outlet 22 of the water storage tank and the electromagnetic pressure relief valve 3, and is used to control the opening and closing of the outlet pipe.
