Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, specifically a corrosion-resistant stainless steel vibration-resistant pressure gauge. Background Technology

[0002] Pressure gauges are instruments that use elastic elements as sensing elements to measure and indicate pressures higher than ambient pressure, and their applications are extremely widespread. When operating in corrosive or vibrating conditions, corrosion-resistant and vibration-resistant pressure gauges are generally required. Traditional vibration-resistant pressure gauges often enhance their fatigue limit simply by selecting the right casing material and increasing its thickness. However, this method cannot meet the long-term use requirements under extremely demanding operating conditions. Stainless steel is preferred to increase its corrosion resistance. Therefore, to address these issues, existing technologies use stainless steel to construct the pressure gauge casing and fill it with media such as glycerin to reduce mechanical vibration interference. However, the glycerin-filled casing suffers from poor sealing performance under vibration conditions, leading to media leakage and affecting its vibration resistance, indicating room for improvement. Utility Model Content
