Description

Technical Field

[0001] This utility model relates to the field of heating pipeline technology, and specifically discloses a heating pipeline pressure regulating device. Background Technology

[0002] Heating pipelines are a collective term for pipeline systems and their ancillary facilities specifically designed for transporting heat media (hot water or steam) in heating systems. They are a core component of the entire heating network (whether it's district heating or building-level heating), responsible for efficiently and safely transporting heat energy from heat sources (such as power plants, district boiler rooms, geothermal stations, industrial waste heat recovery points, etc.) to various heat users (such as buildings, factory workshops, etc.). Pressure regulating devices (also known as pressure regulating valves, pressure reducing valves, pressure stabilizing valves, or pressure control valves) are key equipment for automatically controlling the pressure of fluid (gas or liquid) systems. Their core function is to automatically reduce and stabilize the relatively high and potentially fluctuating pressure on the inlet side at the lower set pressure value required on the outlet side, regardless of changes in inlet pressure or downstream flow rate.

[0003] Existing pressure regulating devices for heating pipelines mostly regulate the pressure within the heating pipeline by installing pressure regulating valves between two heating pipelines. However, traditionally, pressure regulating valves are installed and fixed using flanges. Flange installation requires tightening multiple bolts one by one, resulting in low installation efficiency. In addition, the fixed structure of the pressure regulating valve cannot adapt to the connection requirements of heating pipelines with different spacing, making it inconvenient to use. Utility Model Content

[0004] This utility model proposes a pressure regulating device for heating pipelines, which can facilitate the quick and easy installation and fixing of pressure regulating valves, improve the installation efficiency of pressure regulating valves, and allow the pressure regulating valve to adapt to the connection requirements of heating pipelines with different spacings by adjusting the length of the pressure regulating valve, making it convenient to use.

[0005] This utility model is implemented as follows: a heating pipeline pressure regulating device includes a pressure regulating valve pipeline and heating pipelines located on the left and right sides of the pressure regulating valve pipeline, and a connecting mechanism is provided between the pressure regulating valve pipeline and the two heating pipelines.

[0006] The connecting mechanism includes a movable pipe disposed on one side of the pressure regulating valve pipeline. One end of the movable pipe extends into the interior of the pressure regulating valve pipeline and is fixedly connected to a limit ring. A retaining ring matching the limit ring is fixedly connected to the inner wall end of the pressure regulating valve pipeline. The other end of the movable pipe is connected to an installation ring. Multiple arrayed inclined plates are slidably connected to the other side wall of the installation ring. An inclined groove is opened on the opposite side wall of the multiple inclined plates. An inclined ring matching the inclined groove is fixedly connected to the outer wall of the heating pipeline. An abutment ring that abuts against the installation ring is fixedly connected to the end of the heating pipeline near the movable pipe.

[0007] In a preferred embodiment of the heating pipeline pressure regulating device of this utility model, the outer wall of the mounting ring is threadedly connected to an outer cylinder, and a traction ring is rotatably connected to one end of the outer cylinder near the heating pipeline. The traction ring is slidably connected to multiple inclined plates through trapezoidal limiting sliders and trapezoidal limiting grooves.

[0008] As a preferred embodiment of the heating pipeline pressure regulating device of this utility model, the outer wall of the limiting ring is fixedly connected to a piston ring that abuts against the inner wall of the pressure regulating valve pipeline.

[0009] In a preferred embodiment of the heating pipeline pressure regulating device of this utility model, a sealing gasket is provided between the mounting ring and the abutment ring.

[0010] As a preferred embodiment of the heating pipeline pressure regulating device of this utility model, the outer wall of the outer cylinder is fixedly connected with a plurality of handles arranged in an array.

[0011] In a preferred embodiment of the heating pipeline pressure regulating device of this utility model, the plurality of inclined panels and the mounting ring are slidably connected by trapezoidal limiting sliders and trapezoidal limiting grooves.

[0012] The beneficial effects of this utility model are:

[0013] Two sets of inclined plates are driven by two outer cylinders to move synchronously in opposite directions, allowing the two inclined rings to enter multiple inclined grooves respectively. Through the cooperation between the inclined rings and inclined grooves, the heating pipe can be pulled towards the installation ring, so that the abutment ring and the installation ring are tightly abutted, preventing leakage between the abutment ring and the installation ring. This facilitates the quick and easy installation and fixing of the pressure regulating valve, improving the installation efficiency of the pressure regulating valve. Furthermore, by pushing the moving pipe, the length of the pressure regulating valve pipe can be adjusted, allowing the pressure regulating valve to adapt to the docking requirements of heating pipes with different spacing, making it convenient to use.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 A pressure regulating device for heating pipelines includes a pressure regulating valve pipeline 1 and heating pipelines 2 located on the left and right sides of the pressure regulating valve pipeline 1. A connecting mechanism is provided between the pressure regulating valve pipeline 1 and the two heating pipelines 2.

[0021] The connecting mechanism includes a movable pipe 3 located on one side of the pressure regulating valve pipe 1. One end of the movable pipe 3 extends into the interior of the pressure regulating valve pipe 1 and is fixedly connected to a limit ring 4. A retaining ring 5 matching the limit ring 4 is fixedly connected to the inner wall end of the pressure regulating valve pipe 1. The other end of the movable pipe 3 is connected to an installation ring 6. Multiple arrayed inclined plates 7 are slidably connected to the other side wall of the installation ring 6. An inclined groove 8 is opened on the opposite side wall of the multiple inclined plates 7. An inclined ring 9 matching the inclined groove 8 is fixedly connected to the outer wall of the heating pipe 2. An abutting ring 10 that abuts against the installation ring 6 is fixedly connected to the end of the heating pipe 2 near the movable pipe 3.

[0022] In this embodiment: During installation, the pressure regulating valve pipeline 1 is moved between the two heating pipelines 2. Then, the two moving pipelines 3 are pulled, causing the two abutment rings 10 fixedly connected to opposite ends of the heating pipelines 2 to abut against the opposite side walls of the two mounting rings 6. Multiple inclined plates 7 located on the same side form a group. Then, the two groups of inclined plates 7 move synchronously in opposite directions, causing the two inclined rings 9 to enter the multiple inclined grooves 8. Through the mutual cooperation between the inclined rings 9 and the inclined grooves 8, the heating pipeline 2 can be pulled towards the mounting rings 6, ensuring a tight abutment between the abutment rings 10 and the mounting rings 6, preventing leakage between them. At this time, the pressure regulating valve pipeline 1, the moving pipelines 3, the mounting rings 6, and the heating pipelines 2 are interconnected, thus completing the installation operation of the pressure regulating valve pipeline 1. Figure 1 As shown, this allows for convenient and quick installation and fixing of the pressure regulating valve, improving the installation efficiency of the pressure regulating valve. Furthermore, by pushing the moving pipe 3, the length of the pressure regulating valve pipe 1 can be adjusted, enabling the pressure regulating valve to adapt to the docking requirements of heating pipes 2 with different spacings, making it convenient to use.

[0023] During disassembly, the two sets of inclined panels 7 move synchronously in opposite directions, causing the two inclined rings 9 to move out of the multiple inclined grooves 8 respectively, thereby releasing the fixing state of the heating pipe 2 and completing the disassembly operation of the pressure regulating valve pipe 1.

[0024] As a technical optimization of this utility model, the outer wall of the mounting ring 6 is threadedly connected to the outer cylinder 11, and the end of the outer cylinder 11 near the heating pipe 2 is rotatably connected to the traction ring 12. The traction ring 12 is slidably connected to multiple inclined panels 7 through trapezoidal limiting sliders and trapezoidal limiting grooves.

[0025] In this embodiment: the outer cylinder 11 is rotated, and the outer cylinder 11 moves horizontally on the outer wall of the mounting ring 6 through the thread. The mounting ring 6 drives the traction ring 12 to move. During the movement, the traction ring 12 does not rotate, and drives multiple inclined panels 7 to move relative to or away from each other through the trapezoidal limit slider and the trapezoidal limit groove.

[0026] As a technical optimization of this utility model, the outer wall of the limiting ring 4 is fixedly connected to a piston ring 13 that abuts against the inner wall of the pressure regulating valve pipeline 1.

[0027] In this embodiment, the piston ring 13 can seal the spacer ring 4 and the inner wall of the pressure regulating valve pipeline 1, preventing leakage between the spacer ring 4 and the inner wall of the pressure regulating valve pipeline 1.

[0028] As a technical optimization of this utility model, a sealing gasket 14 is provided between the mounting ring 6 and the abutment ring 10.

[0029] In this embodiment, the sealing gasket 14 can seal the mounting ring 6 and the abutment ring 10, preventing leakage between the mounting ring 6 and the abutment ring 10.

[0030] As a technical optimization of this utility model, the outer wall of the outer cylinder 11 is fixedly connected with a plurality of arrayed handles 15.

[0031] In this embodiment, the handle 15 facilitates the rotation of the outer cylinder 11.

[0032] As a technical optimization of this utility model, multiple inclined panels 7 and mounting ring 6 are slidably connected by trapezoidal limiting sliders and trapezoidal limiting grooves.

[0033] In this embodiment, the inclined panel 7 can be limited by the trapezoidal limiting slider and the trapezoidal limiting groove, so that the inclined panel 7 can move smoothly.

[0034] The working principle and usage process of this utility model are as follows: During installation, the pressure regulating valve pipeline 1 is moved between the two heating pipelines 2, and then the two moving pipelines 3 are pulled so that the two abutting rings 10 fixedly connected to one end of the heating pipeline 2 abut against the opposite side wall of the two mounting rings 6. Then, the two outer cylinders 11 are driven to rotate by multiple handles 15. The two outer cylinders 11 drive the two sets of inclined plates 7 to move synchronously in opposite directions through the trapezoidal limiting slider and the trapezoidal limiting groove, so that the two inclined rings 9 enter the multiple inclined grooves 8 respectively. Through the mutual cooperation between the inclined rings 9 and the inclined grooves 8, the heating pipeline 2 can be pulled to move towards the mounting ring 6, so that the abutting ring 10 abuts tightly against the mounting ring 6. At this time, the pressure regulating valve pipeline 1, the moving pipeline 3, the mounting ring 6 and the heating pipeline 2 are interconnected, thereby completing the installation operation of the pressure regulating valve pipeline 1.

[0035] During disassembly, the two outer cylinders 11 are rotated in the opposite direction, driving the two sets of inclined plates 7 to move synchronously in opposite directions, so that the two inclined rings 9 are moved out from the multiple inclined grooves 8 respectively, thereby releasing the fixed state of the heating pipe 2, thus completing the disassembly operation of the pressure regulating valve pipe 1.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
