Description

Technical Field

[0001] The utility model relates to the technical field of rescue ropes, in particular to a modular composite exhaust valve. Background Art

[0002] The compound exhaust valve is a device used in pipeline systems, mainly used to remove air or gas inside the pipeline. It is usually composed of a valve body, a valve cover, a valve seat and a piston. When the pipeline system is running, gas or air will accumulate at the high points or dead corners of the pipeline, affecting the normal operation of the system and may even damage the pipeline or equipment. The compound exhaust valve releases the accumulated gas or air by opening the exhaust port, keeping the fluid in the pipeline running smoothly and improving the efficiency and stability of the system.

[0003] The existing patent CN206918373U discloses a composite exhaust valve, including a valve body, a valve cover, a valve stem, a valve disc and a floating ball, wherein the left and right sides of the top of the valve cover are respectively provided with a first exhaust port and a second exhaust port, the upper and lower ends of the first exhaust port and the second exhaust port are both installed with valve stem limiting frames, and a protrusion is provided in the first exhaust port and the second exhaust port between the valve stem limiting frames, the valve stem is installed on the valve stem limiting frame, a valve disc is installed on the valve stem between the protrusion and the valve stem limiting frame at its lower end, and fixed ears are installed on the left and right sides of the top of the floating ball, and the fixed ears are fixedly connected with the bottom of the valve stem in the first exhaust port and the second exhaust port by a first fixing bolt, and the valve cover is installed on the valve body. The utility model can quickly discharge the gas in the pipeline through the coordinated use of the first exhaust port and the second exhaust port, and the exhaust effect is good, thereby ensuring the smooth flow in the pipeline and reducing the damage of the gas to the pipeline.

[0004] This patent solves the problem that it is difficult to quickly discharge gas from the exhaust port, which is easy to cause certain damage to the pipeline. However, this patent still has the following shortcomings. For example, when water comes into contact with the internal structure of the valve, it will corrode the structure over a long period of time, causing the sealing surface inside the exhaust valve to become uneven or lose smoothness, thereby reducing the sealing performance and causing the exhaust valve to leak, thereby affecting the normal operation of the system.

[0005] Therefore, the utility model provides a modular composite exhaust valve. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and provide a modular composite exhaust valve.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a modular composite exhaust valve, comprising a valve tank, the bottom end of the inner wall of the valve tank is fixedly connected to a barrier assembly, and the bottom end of the inner wall of the valve tank is fixedly connected to a sealing assembly;

[0008] The partition assembly includes a partition, the bottom end of which is fixedly connected to the valve tank, the bottom end of which is fixedly connected to a water inlet column, a float is provided between the partition and the water inlet column, and the top end of the partition and the top end of the water inlet column are both fixedly connected to a sealing gasket.

[0009] As a preferred embodiment, the sealing assembly includes a limit frame, the top end of the limit frame is fixedly connected to the valve tank, the inner top end of the valve tank is fixedly connected to a sealing airbag, the top end of the limit frame is provided with a valve flap, and the bottom end of the valve flap is fixedly connected to a valve stem.

[0010] The technical effect of adopting the above further solution is: controlling the opening and closing of the valve according to the change of water level, thereby realizing the functions of automatic exhaust and preventing water backflow, and can effectively ensure the sealing of the valve in the closed state.

[0011] As a preferred implementation manner, the top end of the valve tank is fixedly connected to an exhaust column, and the top end of the exhaust column is fixedly connected to a rainproof cover.

[0012] The technical effect of adopting the above further solution is: further enhancing the exhaust function of the exhaust valve, while protecting the equipment from the influence of the external environment, thereby improving the stability and reliability of the equipment.

[0013] As a preferred implementation, the outer side of the float is snap-fitted to the partition, and the outer side of the float is snap-fitted to the water inlet column.

[0014] The technical effect of adopting the above further solution is to ensure that the float can fit tightly on the partition and the water inlet column when rising and falling, thereby avoiding water leakage.

[0015] As a preferred implementation, the outer side of the float is in contact with the bottom end of the valve stem.

[0016] The technical effect of adopting the above further solution is to ensure that the float can accurately transmit signals to the valve stem when the water level changes, thereby more stably controlling the opening and closing of the valve.

[0017] As a preferred implementation, the top end of the valve flap is engaged with the sealing airbag.

[0018] The technical effect of adopting the above further solution is that the sealing effect of the valve when closed can be made more stable, thereby reducing the wear of the valve disc.

[0019] By setting up the interlayer assembly, when the water level drops, the float sinks, triggering the valve stem to open the valve disc, thereby quickly discharging the accumulated gas or air. When the water level rises, the float rises to close the valve and prevent gas from flowing back. This design ensures that when the float floats up and down, the float and the valve tank maintain good sealing, effectively preventing gas and liquid backflow, reducing the corrosion of the internal structure caused by long-term contact with water or gas, and extending the service life of the exhaust valve.

[0020] By setting up a sealing component, when the valve is closed, the sealing airbag is compressed and expands outward to increase the sealing pressure, thereby improving the sealing effect and preventing gas leakage. The sealing airbag expands when compressed to provide additional sealing support, significantly enhancing the airtightness of the valve and reducing the risk of leakage.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 - Figure 3As shown, this embodiment provides a technical solution: a modular composite exhaust valve, including a valve tank 1, the bottom end of the inner wall of the valve tank 1 is fixedly connected to a partition assembly 2, the partition assembly 2 includes a partition 21, the bottom end of the partition 21 is fixedly connected to the valve tank 1, the bottom end of the valve tank 1 is fixedly connected to a water inlet column 22, a float 23 is arranged between the partition 21 and the water inlet column 22, the top of the partition 21 and the top of the water inlet column 22 are fixedly connected with a sealing gasket 24, the partition 21 divides the interior of the valve tank 1 into different areas, the bottom end of the partition 21 is fixedly connected to the valve tank 1, ensuring the stability and sealing of the partition assembly 2, the function of the float 23 is to control the opening and closing of the valve according to the change of water level, and transmit the water level signal by floating, thereby realizing automatic control of the exhaust valve. When the water level rises, the float 23 will float up, and the signal will be transmitted to the valve control system to close the exhaust valve to prevent gas backflow. When the water level drops, the float 23 will sink, triggering the valve to open and realize the flow of gas. The role of the sealing gasket 24 is to ensure the sealing between the float 23 and effectively prevent gas or liquid from leaking from the connection of the valve tank 1.

[0029] Furthermore, Figure 3 As shown: the outer side of the float 23 is engaged with the partition 21, and the outer side of the float 23 is engaged with the water inlet column 22. The float 23 can be firmly fixed on the partition 21 and move up and down with the change of the water level. When the water level rises, the float 23 rises accordingly, pushing the partition 21 to move upward, triggering the valve to close, and preventing the gas from flowing back into. When the water level drops, the float 23 sinks and engages with the water inlet column 22, triggering the valve to open, so as to release the gas.

[0030] In order to solve the problem that the sealing ring may be squeezed or deformed, resulting in the reduction of its sealing performance or failure, such as Figure 1 and Figure 4 As shown, the bottom end of the inner wall of the valve tank 1 is fixedly connected with a sealing component 3, and the sealing component 3 includes a limiting frame 31, the top end of the limiting frame 31 is fixedly connected to the valve tank 1, and the inner top end of the valve tank 1 is fixedly connected with a sealing airbag 34, and the top end of the limiting frame 31 is provided with a valve flap 32, and the bottom end of the valve flap 32 is fixedly connected with a valve stem 33, and the top end of the limiting frame 31 is fixedly connected to the valve tank 1 to ensure the stability and reliability of the limiting frame 31. The function of the sealing airbag 34 is to provide additional sealing support when the valve is closed to ensure that the gas does not leak. When the sealing airbag 34 is squeezed, it can expand outward to increase the sealing pressure. The valve flap 32 is a key component for controlling the flow of gas. When it is not under pressure, it can contact the limiting frame 31 to ensure that no deviation occurs. At the same time, the valve flap 32 is opened and closed by the movement of the valve stem 33, thereby regulating the inflow and outflow of gas.

[0031] The outer side of the float 23 contacts the bottom of the valve stem 33, and the top of the valve flap 32 engages with the sealing airbag 34. When the float 23 rises or falls, it directly affects the position of the valve stem 33, thereby adjusting the opening and closing of the valve to achieve automatic control of the exhaust valve. The top of the valve flap 32 engages with the sealing airbag 34 to ensure a tight fit between the valve flap 32 and the sealing airbag 34. When the valve is closed, the sealing airbag 34 provides additional sealing support to ensure that the gas does not leak;

[0032] The top of the valve tank 1 is fixedly connected with an exhaust column 4, and the top of the exhaust column 4 is fixedly connected with a rain cover 5. The design of the exhaust column 4 and the rain cover 5 at the top of the valve tank 1 ensures the normal operation of the exhaust valve. The exhaust column 4 provides a safe gas exhaust channel, and the rain cover 5 ensures that the exhaust system is protected from external factors.

[0033] Working principle:

[0034] like Figure 1 - Figure 4 As shown:

[0035] During use: when the water level rises in the valve tank 1, the float 23 is floated by the water, and the rise of the float 23 drives the valve stem 33 to move upward, thereby pushing the valve flap 32, prompting the valve to close. When the valve is closed, the sealing airbag 34 is squeezed and expands outward to provide additional sealing force to ensure that the gas does not leak from the sealing point. At the same time, the float 23 contacts the partition 21, and the sealing gasket 24 on the partition 21 prevents water from flowing back into the valve, ensuring that the interior is in a water-free environment. Secondly, when the water level drops, the float 23 sinks and engages with the water inlet column 22. This action drives the valve stem 33 to descend, pushing the valve flap 32 to move toward the limit frame 31, prompting the valve to open, thereby driving the valve flap 32 close to the limit frame 31, causing the exhaust valve to open, allowing the gas to be discharged from the inside of the valve tank 1 through the exhaust column 4.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
