Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of otorhinolaryngology drug administration, in particular to an anti-freezing damage valve. Background Art
[0002] In modern industrial and building systems, valves are key components for controlling fluid flow. They are widely used in fields such as water treatment, heating, water supply, and gas transmission. However, in cold environments, valves face serious freezing problems. These problems not only affect the normal operation of the system but may also cause equipment damage, production interruption, and even pose safety hazards. Therefore, designing and manufacturing valves with anti-freezing functions has become an urgent technical challenge.
[0003] In a low-temperature environment, the moisture in pipes and valves may freeze due to temperature drop. After water freezes, its volume expands, which may cause deformation, cracking, or breaking of the internal components of the valve, affecting the sealing performance and operating function of the valve. In addition, the frozen water may cause pipe blockage, further affecting fluid flow and resulting in abnormal system operation.
[0004] Currently, most valve anti-freezing measures rely on external heating devices, insulating materials, or chemical antifreeze. Although these methods can alleviate the freezing problem to a certain extent, they also have some limitations:
[0005] External heating devices: Require additional energy supply, increasing operating costs and maintenance complexity.
[0006] Insulating materials: Have certain limitations on the installation and use of valves and may have limited effectiveness in extremely cold environments.
[0007] Chemical antifreeze: Improper use may cause chemical pollution to the system and increase usage and maintenance costs.
[0008] Therefore, it is very necessary to invent an anti-freezing damage valve. Content of the Utility Model
[0009] In order to solve the above technical problems, the utility model provides an anti-freezing damage valve to solve the problems that existing valves still lack anti-freezing ability, are prone to freezing of the internal water of the valve due to low temperature, and are easily damaged by the frozen water.

[0013] A water cut-off solenoid valve is fixedly installed inside the pipe at the end of the first drain elbow far from the valve body; first control valves are arranged inside both the first water outlet pipe and the first air inlet pipe.

[0017] The internal structure of the output end is the same as that of the input end, but there is no water cut-off solenoid valve inside it; the internal structure of the output end has the same working mode as that of the input end, but without the participation of the water cut-off solenoid valve, and has the following functions: ① Anti-freezing function: The output end is designed similarly to the input end, including a second drain elbow, a second water outlet pipe, and a second air inlet pipe. These components work together to ensure the drainage of water in the closed state, preventing the residual water from freezing at low temperatures; ② Does not include a water cut-off solenoid valve: Different from the input end, the output end does not install a water cut-off solenoid valve because it is mainly used to drain water from the system, and the drainage function can be jointly realized by the second water outlet pipe and the second control valve without the additional control of the water cut-off solenoid valve.

[0038] Main components and functions
[0039] 1. Valve body 1
[0040] The valve body 1 is the core part of the anti-freezing damage valve. It connects the input end 3 and the output end 5 and is operated through the handwheel 7. A channel is designed inside the valve body for guiding the water flow through the valve system.
[0041] 2. Input end 3

[0044] First control valve 35: Set inside the first water outlet pipe 33 and the first air inlet pipe 34, used to control the inflow and outflow of water and air.
[0045] 3. Output end 5
[0046] The output end 5 includes a second drain elbow 51, a second water outlet pipe 52, and a second air inlet pipe 53. Its design is similar to that of the input end, but it does not include the water cut-off solenoid valve 32.
[0047] The second control valve 54: It is arranged inside the second water outlet pipe 52 and the second air inlet pipe 53 and is used to control the discharge of water and the inflow and outflow of air.
[0048] Working principle
[0049] 1. Valve open state <�
[0050] When the valve is open, water flows from the input end 3 into the valve body 1 and then discharges from the output end 5. At this time, the water in the first drain elbow 31 and the second drain elbow 51 flows smoothly without forming an independent space, so no special anti-freezing measures are required.
[0051] 2. Valve closed state
[0052] When the valve is closed, the water cut-off solenoid valve 32 will close to prevent water from flowing into the first drain elbow 31. At this time:
[0053] An independent space is formed inside the first drain elbow 31, and the first water outlet pipe 33 and the first air inlet pipe 34 are controlled by the first control valve 35 to ensure that the water in the pipeline can be discharged to prevent water accumulation. [[ID=XX]]
[0054] The second drain elbow 51 controls the discharge of water through the second control valve 54 and introduces air to avoid water staying in the pipeline and prevent freezing.
[0055] Summary
[0056] The anti-freezing valve, through a precisely designed drainage and control system, allows water to flow normally when the valve is open and effectively discharges the residual water when the valve is closed, avoiding damage to the valve and pipeline caused by water freezing. This design enables the valve to maintain stable performance in cold environments and prevent equipment failures caused by freezing.
[0057] Using the technical solution described in the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design similar technical solutions and achieving the above technical effects shall fall within the protection scope of the present utility model.
