[0002] A remote exhaust device for a heat pipeline is a device used to exhaust gas in a heat pipeline system. In a heat pipeline system, due to the presence of gas in the pipeline, it will affect the heat transfer effect, and even pose risks such as pipeline blockage and explosion. It is necessary to install a remote exhaust device for a heat pipeline to timely exhaust the gas in the pipeline. The remote exhaust device for a heat pipeline is an essential device in the heat pipeline system and can effectively exhaust the gas in the pipeline.

[0003] However, when exhausting gas in the existing remote exhaust device, the plug cap is connected by a threaded connection. When exhausting gas, it is necessary to manually unscrew the plug cap to discharge the hot gas, and then screw the plug cap back. When in use, it is easy to encounter the situation that it is difficult to close the plug cap, and it is inconvenient to use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a remote exhaust device for a heat pipeline to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A remote exhaust device for a heat pipeline includes a heat pipeline, a remote pipe, and an exhaust device. A number of remote pipes extend from the surface of the heat pipeline, and the other ends of the remote pipes are fixedly sleeved with an exhaust device. The exhaust device includes an exhaust device main body, a sealing head, and a piston rod. A pipe sleeve is arranged at the bottom of the exhaust device main body, and the pipe sleeve is connected to the remote pipe by a thread. A sealing convex block is arranged at the top of the exhaust device main body. The front surface of the sealing convex block is an open surface and is provided with the inner cavity of the exhaust device main body. The other open surface of the inner cavity of the exhaust device main body is located inside the pipe sleeve.

[0007] A connecting plate is arranged at a certain horizontal plane of the inner cavity wall of the exhaust device main body. A piston chamber is arranged on the back surface of the connecting plate. The other end of the piston chamber is in the same vertical plane as the pipe sleeve. A piston rod is slidably connected to the center of the connecting plate. One end of the piston rod is in the same horizontal plane as the top of the sealing convex block. A piston is arranged at the other end of the piston rod. A number of air inlets are arranged on the surface of the piston chamber and below the connecting plate. An air outlet pipe is arranged on the outer surface of the air inlet and at the piston chamber. The other end air outlet of the air outlet pipe passes through the connecting plate and is above the top of the connecting plate.

[0008] Preferably, a fixing notch is formed at the inner top of the sleeve, and a filter screen fixing ring is fixedly connected to the fixing notch through a fixing bolt, and a filter screen is arranged on the inner surface of the filter screen fixing ring.

[0009] Preferably, a spring is sleeved on the surface of the piston rod, one end of the spring is connected to the bottom of the connecting plate, and the other end of the spring is connected to the bottom of the piston.

[0010] Preferably, a sealing head is arranged at the top of the piston rod, a second sealing groove is formed on the top surface of the sealing convex block, a first sealing groove is formed at the bottom of the sealing head corresponding to the second sealing groove, and a sealing ring is fixedly connected to the bottom of the second sealing groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] For a thermal pipeline remote exhaust device of the present invention, when the hot air in the thermal pipeline will compress the piston outward, the piston rod will move outward. At this time, since the hot air is all below the air inlet and no gas flows out, it prevents the unnecessary gas from flowing out when exhaust is not required. When the piston is pushed to the air inlet, the excess hot air will flow out from the air inlet through the outlet pipe and out of the air outlet, and finally flow out from the sealing convex block. Because the whole process is carried out by the pressure of the hot air, the opening and closing of the exhaust device are relatively simple, which is beneficial to use.

[0014] For a thermal pipeline remote exhaust device of the present invention, a filter screen is arranged at the remote pipe connection of the exhaust device and the thermal pipeline. A filter screen fixing ring is arranged on the outer surface of the filter screen, and the filter screen is fixed to the inside of the sleeve through the filter screen fixing ring, so as to filter the impurities in the thermal pipeline. And through the above design, the filter screen can be conveniently disassembled for cleaning.

[0015] For a thermal pipeline remote exhaust device of the present invention, a sealing ring is arranged at the connection between the sealing head and the sealing convex block, and a sealing gasket is also arranged on the surface of the piston, so as to prevent the practicability of the present invention from being reduced due to the insufficient sealing performance inside the exhaust device during use.

A sealing convex block 303 is provided at the top of the exhaust device main body 302.

The other open surface of the inner cavity of the exhaust device main body 302 is located inside the pipe sleeve 301;

[0026] A connecting plate 9 is provided at a certain horizontal plane of the inner cavity wall of the exhaust device main body 302. A piston chamber 10 is provided on the back surface of the connecting plate 9. The other end of the piston chamber 10 is in the same vertical plane as the pipe sleeve 301. A piston rod 5 is slidably connected to the center of the connecting plate 9. One end of the piston rod 5 is in the same horizontal plane as the top of the sealing convex block 303. A piston 6 is provided at the other end of the piston rod 5. A plurality of air inlets 11 are provided on the surface of the piston chamber 10 and below the connecting plate 9. An air outlet pipe 12 is provided on the outer surface of the air inlet 11 and at the piston chamber 10. The other end air outlet 19 of the air outlet pipe 12 passes through the connecting plate 9 and is above the top of the connecting plate 9.

[0027] Furthermore, a fixing notch 13 is provided at the inner top of the pipe sleeve 301. A filter screen fixing ring 14 is fixedly connected to the fixing notch 13 through a fixing bolt. A filter screen 15 is provided on the inner surface of the filter screen fixing ring 14.

[0028] Specifically, a filter screen 15 is provided at the connection between the exhaust device 3 and the remote pipe 2 of the thermal pipeline 1. A filter screen fixing ring 14 is provided on the outer surface of the filter screen 15. The filter screen 15 is fixed to the inside of the pipe sleeve 301 through the filter screen fixing ring 14, thereby filtering impurities in the thermal pipeline 1. And through the above design, the filter screen 15 can be conveniently disassembled for cleaning.

[0029] Furthermore, a spring 8 is sleeved on the surface of the piston rod 5. One end of the spring 8 is connected to the bottom of the connecting plate 9, and the other end of the spring 8 is connected to the bottom of the piston 6.

[0032] Specifically, through the design of the above-mentioned gasket 7 and sealing ring 18, it is prevented that during the use process, due to the insufficient internal sealing performance of the exhaust device 3, the practicality of the present utility model is reduced.

[0033] Working principle: For a remote exhaust device of a thermal pipeline of the present utility model, when the hot air in the thermal pipeline 1 will compress the piston 6 outward, the piston rod 5 will move outward. At this time, since all the hot air is located below the air inlet 11 and no gas flows out, it is prevented that unnecessary gas flows out when exhaust is not required. When the piston 6 is pushed to the air inlet 11, the excess hot air will flow out from the air inlet 11 through the air outlet pipe 12 and out of the air outlet 19, and finally flow out from the sealing convex block 303. Since the whole process is carried out by the pressure of the hot air, the opening and closing of the exhaust device are relatively simple, which is beneficial for use.

[0034] During the compression of the piston rod 5, the spring 8 will be compressed. During the compression of the spring 8, a certain elastic force of inward stretching will occur. When the pressure of the hot air acting on the surface of the piston 6 decreases, the piston 6 will move to the bottom of the air inlet 11, thereby realizing the closing of the exhaust device 3.
