Multiple heating pipelines form a pipeline network. The design pressure of the hot water medium for heating is less than or equal to 2.5MPa, and the design temperature is less than or equal to 200℃; the design pressure of the heating steam medium is less than or equal to 1.6MPa, and the design temperature is less than or equal to 350℃. The design of the following thermal network, since the pipelines in the heating pipeline network operate under high temperature and high pressure conditions, the pipelines in the heating pipeline network will often be damaged and leaked due to changes in temperature and pressure during long-term use.

[0003] Since the pipes in the heating network provide residents with hot water and heating, which are very important and urgently needed living resources, if the main valve of the pipe is directly closed when the pipe is damaged and leaks, it will have a very large impact on the lives of residents. Therefore, the leak-proof maintenance of the pipes in the heating network needs to be carried out while the pipes are in operation. However, the high-temperature hot water or high-pressure steam ejected from the running heating network pipes will affect and hinder the emergency repair work of the maintenance personnel.

[0004] Therefore, it is necessary to improve the existing technology to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a heating pipe network leakage prevention device that is easy to operate. The protective plate can block the high-temperature hot water or high-pressure steam ejected from the damaged pipe to prevent it from directly spraying onto the maintenance personnel and scalding the maintenance personnel, thereby solving the problem that the high-temperature hot water or high-pressure steam ejected from the pipes of the current operating heating pipe network will affect and hinder the emergency repair work of the maintenance personnel.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a convenient-to-operate heating pipe network leakage prevention device, comprising two left and right semi-circular main plates, the inner walls of the two left and right semi-circular main plates are provided with semi-circular grooves, the outer walls of the two semi-circular main plates are symmetrically and integrally formed with semi-circular side plates on the left and right sides, the upper and lower ends of the outer walls of the two semi-circular main plates are fixedly installed with fixed plates, and the fixed plates and the semi-circular side plates on each side are fixedly connected with rubber sealing gaskets.

[0007] As a further technical solution of the present invention, the right sides of the upper and lower pairs of fixing plates are both threadedly connected with locking bolts, and the right ends of the locking bolts are threadedly connected with locking nuts.

[0008] As a further technical solution of the present invention, the fixing plates on each left and right side and the rubber sealing pads on the semi-circular side plates are integrally formed.

[0009] As a further technical solution of the present invention, protective plates are fixedly installed on the opposite sides of the outer walls of the semi-circular main body plates on the left and right sides, and mounting handles are fixedly installed on the opposite sides of the outer walls of the two protective plates.

[0010] As a further technical solution of the present invention, the protective plate is made of high-temperature resistant transparent plastic material.

[0011] As a further technical solution of the present invention, a pressure relief pipe connected to the semi-circular groove is fixedly installed on the right end of the outer wall of the semi-circular main body plate on the right side, and a valve is fixedly installed on the pressure relief pipe, and a rotating handle is provided on the valve.

[0012] The utility model provides a heat supply pipe network leakage prevention device that is easy to operate and has the following beneficial effects compared with the prior art:

[0013] 1. The utility model can fix each pair of fixing plates on the left and right sides by tightening the locking bolts and locking nuts on the upper and lower sides, thereby fixing the semi-circular ring-shaped main plates on the left and right sides. The rubber sealing pads on the left and right sides form a sealing treatment between the device and the pipeline, thereby completing the leak treatment at the damaged and leaking part of the pipeline.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution for a heat supply pipe network leakage prevention device that is easy to operate: it includes two semi-circular ring-shaped main body plates 100 on the left and right, and the inner walls of the two semi-circular ring-shaped main body plates 100 are each provided with a semi-circular ring-shaped groove 110. The outer walls of the two semi-circular ring-shaped main body plates 100 are symmetrically and integrally formed with semi-circular ring-shaped side plates 120 on both sides. The upper and lower ends of the outer walls of the two semi-circular ring-shaped main body plates 100 are fixedly installed with fixing plates 200. The fixing plates 200 and the semi-circular ring-shaped side plates 120 on each side are fixedly connected with rubber sealing gaskets 300. The two semi-circular ring-shaped main body plates 100 are buckled on the pipe wall where the pipeline 1 is damaged and leaking, and the rubber sealing gaskets 300 are fixedly connected on the left and right sides. The rubber sealing gasket 300 forms a seal between the device and the pipeline, thereby completing the leak treatment at the damaged leaking part of the pipeline 1. The rubber sealing gasket 300 on the fixing plate 200 on each left and right side and the semi-circular side plate 120 are all integrally formed, thereby reducing the gap in the device and improving the sealing effect of the device. The right sides of the upper and lower pairs of fixing plates 200 are threadedly connected with a locking bolt 210, and the right end of the locking bolt 210 is threadedly connected with a locking nut 220. By tightening the locking bolts 210 and the locking nuts 220 on the upper and lower sides, each pair of fixing plates 200 on the left and right sides can be fixed, thereby achieving the fixation of the semi-circular main plates 100 on the left and right sides.

[0023] like Figure 1-4As shown, protective plates 400 are fixedly installed on the opposite sides of the outer walls of the semi-circular main body plates 100 on the left and right sides. The protective plates 400 can block the high-temperature hot water or high-pressure steam ejected from the damaged part of the pipe 1 to prevent them from being directly sprayed onto the maintenance personnel and scalding the maintenance personnel. Installation handles 410 are fixedly installed on the opposite sides of the outer walls of the two protective plates 400. Maintenance personnel can use the installation handles 410 to carry, move and install the device. The protective plates 400 are made of high-temperature resistant transparent plastic material. The use of transparent plastic material can facilitate maintenance personnel to observe the situation inside the protective plates 400 during installation.

[0024] like Figure 1 、 Figure 2 and 4 As shown, a pressure relief pipe 500 connected to the semi-circular groove 110 is fixedly installed at the right end of the outer wall of the right semi-circular main plate 100, and a valve 510 is fixedly installed on the pressure relief pipe 500. The valve 510 is provided with a rotating handle 520. During installation, the valve 510 can be opened by first rotating the rotating handle 520, and the high-temperature hot water or high-pressure steam at the leakage point is guided out through the pressure relief pipe 500 connected to the semi-circular groove 110, thereby reducing the pressure when the two semi-circular main plates 100 are closed and installed. After the two semi-circular main plates 100 are fixed and installed, the valve 510 is closed to seal the device.

[0025] The working principle of the present invention is as follows: when the pipe 1 is damaged and leaking, the maintenance personnel can move the device to the damaged and leaking pipe wall by holding the installation handle 410. The high-temperature hot water or high-pressure steam ejected from the damaged part of the pipe 1 can be blocked by the protective plate 400 to prevent it from being directly sprayed onto the maintenance personnel and scalding them. By tightening the locking bolts 210 and locking nuts 220 on the upper and lower sides, each pair of fixing plates 200 on the left and right sides can be fixed, thereby achieving the fixation of the semi-circular main body plates 100 on the left and right sides. The rubber sealing pads 300 on the left and right sides can be used to fix the device and The pipeline is sealed, thereby completing the leak treatment at the damaged leaking part of the pipeline 1. At the same time, if the pressure in the pipeline 1 is too high, which causes inconvenience in the closing and installation of the semi-circular main plates 100 on both sides, the maintenance personnel can first open the valve 510 by turning the handle 520, and guide the high-temperature hot water or high-pressure steam at the leaking part to be discharged through the pressure relief pipe 500 connected to the semi-circular groove 110, thereby reducing the pressure when the two semi-circular main plates 100 are closed and installed. After the two semi-circular main plates 100 are fixed and installed, the valve 510 is closed to seal the device.

[0026] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
