[0033] In an embodiment, the spring compressor has M14 fine threads.
[0034] The manner in which the proposed valve is decribed, in further details in conjunction with FIGs. 1-4. It may be noted that these figure is only illustrative, and should not be construed to limit the scope of the subject matter in any manner.
[0035] FIGs. 1-3 illustrate exemplary perspective views of a pressure relief valve, according to embodiments of present disclosure.
[0036] FIG. 4 illustrates an exemplary internal view perspective view of a pressure relief valve, according to embodiments of present disclosure.
[0037] As illustrated in FIGs. 1-4, a pressure relief valve 100 (i.e. valve) is depicted. The application of this valve is integral in systems where maintaining optimal water pressure is crucial, such as in water heaters. This valve is designed to prevent potential damage to the water heater and associated components, ensuring the safety and efficiency of system, where it is attached. The pressure relief valve 100 includes a valve body 102, equipped with a set of internal threads 104 and a set of external threads 106 constructed from brass material. The internal threads are further equipped with 1/8 BSP or 3/8 BSB inch fine pitch engagement, highlighting a precise threading system. This configuration serves a crucial purpose in the valve's application, particularly in water heater systems. The fine pitch engagement ensures secure and accurate threading, contributing to efficiency and reliability of the pressure relief valve. The brass material adds durability and corrosion resistance to these threaded components, emphasizing the valve's suitability for prolonged use in demanding environments.
[0038] In an embodiment, the valve body 102 includes a stainless steel (SS) material spring 108 (interchangeably referred to as spring 108, hereinafter), as shown in FIG. 4, movably attached within the valve body to facilitate controlled compression in response to water pressure exceeding a predefined value, specifically set at 8 bar. The attachment of the spring 108 is integral to the valve, connecting to a spring compressor within the valve body 102. When water pressure surpasses the predetermined threshold, the spring undergoes compression, activating the valve to release excess pressure. The connection between the SS spring and the spring compressor ensures a responsive and reliable operation, preventing damage to the system by regulating pressure within the water heater.
[0039] The spring compressor engages with a brass nut within the valve body 102, utilizing M14 fine threads. Its purpose is to provide a means for precise adjustment of the compression force applied to the spring 108. By including M14 fine threads, the spring compressor allows for meticulous tuning, enabling operators to customize the valve's response to specific water pressure requirements. This adjustment capability ensures the valve's adaptability to varying conditions, enhancing its versatility and effectiveness in maintaining optimal pressure levels within the water heater system. The engagement of the spring compressor with a brass nut (110), coupled with the use of fine threads, underscores the importance of this component in achieving accurate and controlled compression of the spring 108.
[0040] In an embodiment, the valve body 102 includes a sealing mean (not shown) to ensure a water-tight seal, preventing any leakage or loss of water from system, where the valve is attached. The sealing mean is connected within the valve body in a manner that establishes an effective barrier against water escape when the valve is in the closed position.
[0041] In an embodiment, the valve body 102 a brass thread insert (114-a), and a brass sealer insert (114-b), as shown in FIGs. 3 and 4. The brass thread insert (114-a) serves as a robust sealing element within the valve body. Brass is commonly used in such applications due to its corrosion resistance and reliability in creating durable seals. Additionally, the brass sealer insert (114-b) is designed to enhance the threading system within the valve body, providing secure and effective engagement between threaded components. The use of brass ensures durability and resistance to corrosion in this critical area. Thus, material used for the insert sealant part are crucial for maintaining the integrity of the valve, preventing leaks, and ensuring the efficient operation of the pressure relief mechanism.
[0042] In an embodiment, the valve body 102 includes a bar spring holder 116 (as shown in FIG. 4) made of Polyoxymethylene (POM) material. This bar spring holder includes two essential components:
[0043] a) Silicon Washer 118: The silicon washer 118 (as shown in FIG. 4) is a critical element within the bar spring holder. It is specifically rated for 8 bar pressure, indicating its ability to withstand and effectively seal against water pressure up to that limit. Silicon is chosen for its resilience and capacity to maintain a reliable seal under varying pressure conditions.
[0044] b) Stainless Steel (SS) Material Spring Plate 120: The spring plate 120 (as shown in FIG. 4), crafted from Stainless Steel, is another integral component of the bar spring holder. Also rated for 8 bar pressure, the spring plate works in conjunction with the silicon washer to support and control the compression of the stainless steel spring within the valve. Stainless steel is known for its durability and corrosion resistance, making it suitable for applications involving pressure and mechanical stress.
[0045] Thus, the bar spring holder 116 (as shown in FIG. 4) contributes to reliability and effectiveness of the pressure relief valve. The silicon washer ensures a secure seal, while the stainless steel spring plate provides structural support for the spring 108, both rated for pressures up to 8 bar. This bar spring holder 116 ensures the proper functioning of the valve under varying water pressure conditions.
[0046] In an embodiment, the valve body 102 includes a bottom spring cap (not shown) and a threaded bar spring lever cap (not shown) both made of Polyoxymethylene (POM) material. The bottom spring cap contributes to structural integrity of the pressure relief valve. It likely serves as a protective barrier and base for the components within the valve body 102. The use of Polyoxymethylene (POM) material for the bottom spring cap is chosen for its durable and resistant properties, ensuring that this component can withstand the operational conditions of the valve. Further, the bottom spring cap provides a secure base for the spring mechanism and contributes to stability of the valve.
[0047] Additionally, use of Polyoxymethylene (POM) material for the threaded bar spring lever cap is chosen for its robustness and resistance, ensuring durability during adjustments and operation. The threaded bar spring lever cap is connected to the spring compressor and other components involved in adjusting the spring's compression force. The threaded nature of this cap implies a connection to the fine threads of the spring compressor, enabling precise adjustments.
[0048] In an embodiment, the valve body 102 includes a lever plate (not shown) of Stainless Steel (SS) material. Stainless steel is chosen as the material for the lever plate due to its known properties of durability, corrosion resistance, and mechanical strength. The lever plate is involved in the movement and operation of the valve, especially during the release of excess pressure. The lever plate provides structural support, particularly in lever mechanism, ensuring the reliable operation of the pressure relief valve. Further, stainless steel is resistant to corrosion, making the lever plate well-suited for applications involving exposure to water and moisture. This property ensures that the lever plate maintains its integrity over time, even in demanding environmental conditions.
[0049] Thus, the present disclosure discloses the pressure relief valve that offers a cost-effective solution by utilizing a combination of materials, reducing production costs while maintaining efficiency and reliability. With features such as a versatile spring adjustment mechanism, adaptive sealing technology, and a diverse material composition, the proposed valve ensures optimal performance, ease of operation, and long-term durability in water heater applications.
