Description

A breather valve with integrated humidity indication Technical Field

[0001] This utility model relates to the field of breathing valve technology, and more specifically, to a breathing valve with integrated humidity indication. Background Technology

[0002] In modern industrial production and storage, various containers are widely used for the storage and transportation of liquids, gases, and other substances. Among them, the breather valve is a key component that ensures the safe operation of the container, and its performance directly affects the safety and service life of the container.

[0003] Traditional breather valves are often limited in function, typically offering only basic pressure and vacuum regulation, which is insufficient to meet the increasingly complex demands of industrial applications. For example, in storage scenarios sensitive to environmental humidity, traditional breather valves cannot monitor changes in humidity inside the container in real time. This can lead to spoilage or damage of stored materials due to humidity issues, resulting in significant economic losses for businesses.

[0004] Furthermore, traditional breather valves suffer from numerous structural design flaws. Their internal airflow path is often complex, with pressure release and vacuum release functions typically sharing a single path. This not only increases gas flow resistance and reduces the valve's efficiency but can also lead to interference between the pressure and vacuum release processes, affecting the valve's stability and reliability. Simultaneously, this flawed airflow design makes it difficult to integrate other functional modules, such as humidity indicators, into traditional breather valves, limiting their functional expansion.

[0005] In terms of ease of operation, traditional breather valves also have significant shortcomings. When there is residual pressure inside the container, opening the container often requires specialized tools or complex operating procedures, which not only increases the labor intensity of operators but also poses certain safety hazards. Moreover, traditional breather valves are often not ideal in terms of material selection, and the seals are prone to aging and wear, resulting in a decline in sealing performance. This necessitates regular on-site maintenance and replacement, increasing the company's maintenance costs and downtime.

[0006] Therefore, developing a breathing valve with novel structure, diverse functions, convenient operation and reliable performance is of great practical significance. Summary of the Invention

[0007] To overcome the shortcomings of the prior art, this utility model provides a breather valve with integrated humidity indication.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a breather valve with integrated humidity indication, comprising a valve body, the valve body mainly consisting of a spring seat, a valve stem, a second nut, and an adjusting nut, wherein a first spring is elastically connected between the second nut and the spring seat, a transparent cover is installed on the right side of the valve body, a button nut located on the right side of the transparent cover is installed on the right side of the valve stem, a second O-ring seal located in the recess of the transparent cover is installed inside the valve body, a second sealing gasket is installed on the right side of the spring seat, a first nut is provided above the valve body, a first sealing gasket is installed on the right side of the first nut, a first O-ring seal located between the first sealing gasket and the transparent cover is provided above the interior of the valve body, a locking nut located on the right side of the first O-ring seal is installed on the right side of the transparent cover, and a humidity indicator disc located inside the transparent cover is installed on the right side of the valve body;

[0009] As a preferred embodiment of this utility model, an adjusting nut is provided inside the valve body, and a second spring located inside the first spring is elastically connected between the adjusting nut and the spring seat. The second spring is used to adjust the positive pressure, and the first spring is used to adjust the negative pressure.

[0010] As a preferred embodiment of the present invention, the second sealing gasket, the first sealing gasket, the first O-ring and the second O-ring are all annular and are distributed sequentially from left to right, with the first O-ring and the second O-ring being located at the same longitudinal position.

[0011] As a preferred embodiment of this utility model, the valve stem passes through the center of the valve body, and the right end of the valve stem passes through the valve body and is threadedly connected to the button nut.

[0012] As a preferred embodiment of this utility model, the spring seat is pagoda-shaped, and has two grooves inside for placing the first spring and the second spring, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] With its unique and innovative structural design, the breather valve has demonstrated a series of significant beneficial effects, bringing great convenience and advantages to applications in related fields.

[0015] From a structural design perspective, this breather valve is novel and unique, cleverly integrating a humidity indicator and a two-way vent valve. This integrated design significantly saves space, allowing the breather valve to perform multiple functions within a limited space, meeting the compact requirements of modern industry. In industrial production, many storage containers occupy limited space. Traditional breather valves, due to their single function and dispersed structure, often require a large installation space. The breather valve effectively solves this problem, providing greater flexibility in equipment layout.

[0016] The breather valve features an independent design for both pressure and vacuum release functions, with a separate air path leading to the humidity indicator. This independent air path design avoids mutual interference between airflows during pressure and vacuum release, resulting in more precise and efficient pressure and vacuum regulation. Simultaneously, the independent air path ensures the humidity indicator accurately acquires humidity information within the container, providing reliable protection for humidity monitoring. In practical applications, this precise pressure and vacuum regulation, along with accurate humidity monitoring, effectively protects the substances stored within the container, preventing damage caused by abnormal pressure or humidity changes.

[0017] This breather valve features a large flow rate, with a maximum flow rate reaching the set value. This characteristic allows the valve to quickly respond to pressure changes within the container, promptly adjusting pressure and vacuum to ensure stable internal pressure. In industrial production processes sensitive to pressure changes, such as the storage and transportation of chemical raw materials, rapid pressure regulation effectively prevents safety accidents caused by excessively high or low pressure, ensuring smooth production operations.

[0018] The fact that the resealing pressure after the valve is opened is not less than the set value demonstrates the good sealing performance of the breather valve. During container pressure regulation, the breather valve needs to be opened and closed frequently. Good sealing performance can prevent leakage of substances inside the container, avoid environmental pollution, and also ensure the purity and quality of the substances inside the container.

[0019] The manual release button is another highlight of this breather valve. During container use, residual pressure may exist, increasing the difficulty of opening the container and potentially causing safety accidents. The manual release button allows operators to safely and conveniently release residual pressure inside the container without disassembling the breather valve, significantly reducing the difficulty and risk of opening the container and improving operational efficiency and safety.

[0020] In terms of material selection, the breather valve is made entirely of corrosion-resistant materials, with silicone rubber used for the seals. The use of corrosion-resistant materials allows the breather valve to operate stably for extended periods in harsh industrial environments, resisting the erosion of various chemicals and extending the equipment's service life. Silicone rubber seals are lightweight, flexible, and offer excellent sealing performance, further enhancing the breather valve's sealing properties and durability. Moreover, this breather valve requires no on-site maintenance, reducing maintenance costs and downtime for businesses and improving production efficiency.

[0021] In conclusion, breather valves, with their novel structural design, superior performance, and reliable material selection, have broad application prospects in industrial storage and transportation, and can bring significant economic and social benefits to enterprises.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figure 1, this utility model provides a breather valve with integrated humidity indication, including a valve body 12. The valve body 12 is mainly composed of a spring seat 8, a valve stem 10, a second nut 16, and an adjusting nut 18. A first spring 13 is elastically connected between the second nut 16 and the spring seat 8. A transparent cover 6 is installed on the right side of the valve body 12. A button nut 9 located on the right side of the transparent cover 6 is installed on the right side of the valve stem 10. A second O-ring seal 11 located in the recess of the transparent cover 6 is installed inside the valve body 12. A second sealing gasket 3 is installed on the right side of the spring seat 8. A first nut 1 is provided above the valve body 12. A first sealing gasket 2 is installed on the right side of the first nut 1. A first O-ring seal 4 located between the first sealing gasket 2 and the transparent cover 6 is provided above the inside of the valve body 12. A locking nut 5 located on the right side of the first O-ring seal 4 is installed on the right side of the transparent cover 6. A humidity indicator 7 located inside the transparent cover 6 is installed on the right side of the valve body 12.

[0026] The breather valve connects to the pressure vessel via external threads on the housing. An integrated humidity indicator monitors the humidity of the pressure vessel, features bidirectional venting, releases pressure based on the pressure difference between the inside and outside of the valve, and also has a manual pressure release function.

[0027] The main function of the breather valve is to balance the pressure inside and outside the pressure vessel and monitor the humidity inside the pressure vessel. When the pressure inside the pressure vessel is higher than the external pressure, the breather valve opens to release air. When the pressure inside the pressure vessel is lower than the external pressure, the breather valve opens in the reverse direction to supply air. It has a bidirectional ventilation function, maintaining pressure balance inside and outside the pressure vessel over a long period. It also integrates a humidity indicator to monitor the humidity of the pressure vessel and has a manual pressure release function.

[0028] The main functions of the breather valve are to balance the pressure inside the pressure vessel, monitor the humidity inside the pressure vessel, and manually release the pressure inside the pressure vessel. When the pressure difference between the inside and outside of the pressure vessel is positive (set value), the breather valve opens, releasing gas. When the pressure difference is negative (set value), the breather valve opens in the reverse direction, supplying gas. When the pressure difference is balanced (set value), the breather valve closes. This valve must have bidirectional ventilation to maintain pressure balance inside and outside the pressure vessel over a long period. An integrated humidity indicator monitors the humidity of the gas inside the pressure vessel; the humidity indicator is reversible and changes with humidity. An integrated manual release device is used to release the pressure inside the pressure vessel.

[0029] Figure 1 shows a breather valve. Its air circuit principle is as follows: when the internal and external pressure difference is balanced, the valve is in the neutral position and closed; when the internal pressure increases, it pushes the valve core in the forward direction, opening the valve; when the internal pressure decreases, it pushes the valve core in the reverse direction, opening the valve; manually pressing the button pushes the valve core in the reverse direction, releasing the internal pressure. The breather valve is installed on the pressure vessel via threads and a sealing gasket. The number of breather valves installed is generally determined according to the size of the pressure vessel. Its main operating mode is as follows: when the internal and external pressure difference of the pressure vessel is balanced and less than the set value, the valve core is in the neutral position, the valve is closed, and the pressure vessel is sealed; when the pressure inside the pressure vessel is greater than the external pressure, the pressure difference is greater than the set value, the valve core extends, the valve opens, and pressure is released outward until the valve closes again; when the pressure inside the pressure vessel is less than the external pressure, the pressure difference is greater than the set value, the valve core retracts, the valve opens, and air is supplied inward until the valve closes again. When the pressure vessel needs to be opened, the release button is manually pressed to release the residual pressure inside the vessel, making it easier to open. An independent humidity channel is set up, leading to an integrated humidity indicator. The humidity indicator card is isolated from the outside world by a transparent cover, making it easy to observe the humidity inside the pressure vessel at any time.

[0030] The valve body 12 is equipped with an adjusting nut 18. The adjusting nut 18 is elastically connected to the spring seat 8 by a second spring 14 located inside the first spring 13. The second spring 14 is used to adjust the positive pressure, and the first spring 13 is used to adjust the negative pressure.

[0031] Among them, the second sealing gasket 3, the first sealing gasket 2, the first O-ring 4 and the second O-ring 11 are all annular, and they are distributed sequentially from left to right. The first O-ring 4 and the second O-ring 11 are distributed in the same longitudinal position.

[0032] The valve stem 10 passes through the center of the valve body 12, and the right end of the valve stem 10 passes through the valve body 12 and is threadedly connected to the button nut 9.

[0033] The spring seat 8 is pagoda-shaped and has two grooves inside, which are used to hold the first spring 13 and the second spring 14, respectively.

[0034] Working principle and usage process of this utility model:

[0035] When the internal and external pressure difference is balanced, the valve is in the neutral position and closed. When the internal pressure increases, the valve core is pushed forward, opening the valve. When the internal pressure decreases, the valve core is pushed backward, opening the valve. Manually pressing the button pushes the valve core backward, releasing the internal pressure. The breather valve is installed on the pressure vessel via threads and a sealing gasket. The number of breather valves installed is generally determined by the size of the pressure vessel. Its main operating principle is as follows: When the internal and external pressure difference of the pressure vessel is balanced (less than the set value), the valve core is in the neutral position, the valve is closed, and the pressure vessel is sealed. When the pressure inside the pressure vessel is greater than the external pressure (pressure difference greater than the set value), the valve core extends, the valve opens, and pressure is released until the valve closes again. When the pressure inside the pressure vessel is less than the external pressure (pressure difference greater than the set value), the valve core retracts, the valve opens, and air is supplied until the valve closes again. When it is necessary to open the pressure vessel, the release button is manually pressed to release the residual pressure inside the vessel, facilitating its opening.
